Short answer: No. Medium answer: No, because you still need to conjure the things out of thin air to bolt them to a NA to make it a NA+T. Long Answer: No - The things you need to conjure - meaning a turbo, intercooling, manifolds, exhaust, intake/manifold/piping, clutch, injectors, fuel pump, AFM (?), ECU + Wiring (woo, N/A loom fun) have to come from somewhere. You could have many scavenged these things from an OEM car that someone had upgraded from and use some of these. This will be cost prohibitive now, especially so in the USA. You'd probably pay the same for newer, upgraded components that are better than old OEM stuff from 25-30 years ago. None of these big ticket items are re-usable for the N/A car. Why not buy new and upgrade while you're there? The only real consideration is turbo and fuel sizing and determining whether you want to stay within the bounds of the OEM engine or get into rebuild territory. These limits ARE lower with a N/A motor and especially N/A gearbox at the starting point. And if you're gonna upgrade those then you may as well consider having them built to begin with. Because everyone here knows you're never far from that next engine rebuild once you start making the power you want... The cars you see on the internet and SAU etc have been built over decades. If you're really clued in... you would sell your US car to somebody for what you paid for it. You would then scour AU JDM pages or SAU and buy a car like Dose's on this forum with your powerful American Dollar. This will save you so much money in the long term. Importing it could be tricky. Or it might not because USA. I have long said the only reason 90's Japanese stuff took off was because a) Japanese people had Japanese cars so that is what they used b) Australians could import these cars to Australia with very minimal changes and use them on the road here c) Neither country had well-priced access to US or EU Sports Cars. I don't believe the JDM scene would have taken off in Australia at all if we had EU priced EU BMW M offerings, or more especially the AUS V8 Scene would never have existed if we had the multitude of US cars like Camaros, Mustangs, Corvettes at the prices you folks do. After all - Do the math. I would say put a V8 in your R34 and that's the smart way forward. It is. I did it. I know this from my own experience. But at that point there's no reason to simply not buy a C5 or C6? It would be simpler and easier and cheaper and bette-

So you can then buy a more expensive, less reliable, more boring and slower replacement that's harder to work on and you have no knowledge of?

Thank god. I thought I was the only one, nobody seems to mention this (cause nobody really goes this far in Sedan land). The car's track is 10mm wider at the rear, which explains why the rears sit a little further out for the same size wheels. There's not really many options in widebody land for sedans anyway - People will just use whatever came out of the box and then buy wheels/spacers to suit. To get it perfect you'll likely need custom wheels with custom offsets if you really want to get it perfect which is what I plan to do, but I also plan to utilize more of the inboard space for tyres at the rear... which is also something nobody ever seems to do.... OR my maths have failed me after 20,000 attempts and I'm about to make huge mistakes.

The car remains in paint jail. I am now pretty convinced that the whole "RB25 Airboxes are kinda limiting to ~300kw" could be a thing. Also saw a good video from Engine Masters: (Sorry for FB link) (https://www.facebook.com/watch/?ref=search&v=761771519471924&external_log_id=c10bcbb6-2c39-4ff3-9240-287e9921fde6&q=Cold Air Considerations) Where they tested Pod Filter sizes and kept adding bends to a LS3 on an Engine Dyno to find if bends caused power loss. It's a good video worth watching - They did lose ~25hp from making an intake which had 3x90's and a 120 degree. They only lost maybe 1hp with a basic 90. I feel that by sealing up my airbox I have: 1) Created the same restriction a stock airbox would have. 2) Created a very convoluted set of intake 'pipes' by forcing all the air through the ducts. So I am pretty confident I'll be going full circle and have a huge hot air intake pod and actually see a benefit. The air does *not* stay hot once it gets flowing, aided by the ducts, and the pod can then pull air from anywhere. All the posts of yore talk about the stock airbox costing 10-15kw at 300kw+ but you know what? I f**king would very much like that 10-15kw and I remember my own pod filter in engine bay experiences. Turns out the GTT Reo and Headlight brackets really don't allow you to mount GTR items, no matter what the internet says. Various brackets have had to be made up to actually make it fit right for the front bar. Also some idiot mounted a 3L Accusump right where the bumper wants to go, so that has had to be 'relocated' To where, I am still not sure, but it's supposedly mounted in the pictures and I can't see it.

Mine was great for years too!

YES. If you have a walbro on stock wiring gauges it WILL melt. Perhaps if you are some level of amazing crimping genius it may not. It may seem fine for ~8 years with bulkhead connectors and then melt when you're interstate in NSW and need a 1000km tow home after waiting 10 hours. Ask me how I know. This depends on whether your car is stockish, or whether you need to keep it going in the meantime. Depends on the power you want. The JJ DeatschWerks kits can utilize (and do) stock wiring/pump/plugs. They won't do much more than 320 (?) kw on depending on your boost level and E85 use. They flow more on 98. If you need more than that... and have the cash and are going to do it anyway? Do it now. I would not be putting a Walbro 525 in my car without some upgraded AN fittings/bulkheads/etc that Frenchies use. just do the FPG hat/bulkhead fix at the same time and never worry once you put it all back together and have peace of mind.

Nah, I definitely do that kind of stuff with my car. I do drive it around as a daily! It's just that mindset about building a car to actually still use/retain it's function as a car is rare. If you modify your car into a weekender, IMO you've ruined 5/7ths of the fun. It should remain fun to do daily errands in.

I am glad someone's project fun car is out doing stuff like this.

Yeah - I found the same information too.. 30% open is like 85% of flow etc. So it's probably going to be minor if not completely imperceptible. I also have a larger pod filter here, will swap that on and see if there's any difference. The hardest part is finding a place to uh, test this. It's quite noticable just how much having ducting to the otherwise completely open pod cools the intake temps down. It's better boxed, or shielded but driving for 30 seconds really makes it plummet to near ambient temperatures. I recall in the past when I was a RB land and had a nice flowing airbox - - Then I took the lid off and put a pod there, and gained 9 psi of boost and about 60kw from the restriction I didn't know I had - with the controller at same duty cycle. However finding people using over the radiator intakes having similar KPA drops at WOT on built setups makes me think there restriction could be the exhaust or potentially the headers. Either way though, there's no real estate to play with and nothing that can realistically be done about it. The original dyno plot without the airbox, and the larger pod had a better curve. It was later I added the ducting and airbox, and a smaller pod to make it fit in there...

The problem with FB/Insta/Reddit etc comments relating to cars is simple. You get to ask a question once, and get one round of replies. For things that can actually be answered in a few lines of text, once, it's fine. After 6 hours, your original question is lost to the void. There are no follow ups, additional questions, anything. No project car is ever such a simple list of questions to ask. You need discussion.

They're notoriously difficult if you traverse forums... the 102TB and FAST102 are so bad that most people actively don't buy it unless they REALLY want that extra 1hp. The idle stuff isn't really that hard. The cam is pretty manageable and while it acts like a larger cam the whole car actually drives smoother than before. I like to just tinker so if I can get 50rpm less variance or rule out situations where it does 'unexpected' things it's fun for me. HOWEVER If you just let a tuner give it a guess for a couple of hours and had no way/desire to test and tweak it yourself you'd spend a lot of money at the tuner or be pretty frustrated, that's for sure. But yeah. Drives great. (then I drive partner's Civic Type R and I think.. well, more tweaking to do) But for what it is (cam, TB, intake, manual etc) it does commute around really great once you figure out how the idle tables and GM's systems intend to work.

I might be the only guy to be able to go back to the dyno like:

So, in the effort of pulling apart airboxes and testing enclosures to see if this aids in MAP loss at WOT I noticed: 1) The ducts up the OEM intercooler holes from the front bar help IAT drastically, whether the pod is shielded from the engine bay by an airbox missing a lid, or an airbox WITH a lid. Plus you get more induction sound without the lid. Having half the airbox (with no lid) acting as a barrier to the headers seems to help. 2) For shits and giggles I checked the TB. This was full pedal travel. This is actually full travel of the TB. Photos aren't perfect, but there was definitely an amount of play in it and it wasn't against the stop. After much swearing and adjusting the pedal, I realised that the cable is actually too long for the skyline pedal travel to fully articulate it. Having the pedal adjusted so WOT was actually hard open on WOT resulted in an idle of 3500rpm. As an aside, this was also the TPS registering at 3.1%. I removed the above to give the pedal enough travel to actually fully open the TB. I now get a satisfying 'thonk' on full open and full closed which you can hear pumping the pedal as it hits the TB stops (with the bonnet open and intake back on). Luckily for me, the screw screws into a raised metal boss under this plastic piece that is now acting as the new throttle stop. I've gained about 20mm (ish) of pedal travel and I can move it maybe a mm or two post open-thonk before it's hard against the stop. After all of this I did a bit of road tuning because a 102MM throttle is sensitive. The difference between holding an 950rpm idle and instantly stalling is about 0.4% of TPS movement. Will that help? I suppose it can't hurt. I set 'closed' point back to where it was, I can definitely feel the extra pedal travel that is needed to actually open the TB fully. But this morning I dropped the car off at Paint Jail again, so who knows when this will re-eventuate out to see if it helps with the top of the dyno hitting a ceiling.

Take heart that everyone else seems to have found a way. The OEM S1 indicators do slot in pretty firmly. It may simply be a case of having them sit slightly looser and nobody actually ever noticed this when attempting to remove a indicator from a JSAI bar :p

I mean the stuff on the side. It really depends on what the JSAI bar has - I'll make the assumption it has the strakes and that the end is just a flat piece. Otherwise....

Apex wheels are the go-to for all things BMW. They have quite the level of information on weight, fitment and other things. A friend who had an E36 was extremely happy with the wheels he got from them. They should answer anything potentially answerable on the subject. :p https://apexwheels.com/fitment-guides/bmw/3-series/bmw-e90-e91-e92-e93-3-series-wheel-and-tire-fitment-guide

I hate to be this guy, as I just sold my bumper. But it's not as simple as merely a hole. It's actually quite contoured. This is from a GTR, but yeah. It is not just a straight shape.

I mean, I can confirm the TPS is at 100%.... I can confirm when we installed the TB and setup the cable that the TB was indeed fully open at max pedal travel.. the same 'curve' (WRT MAP vs MAP) existed with the previous setup/TB/manifold as well... No, we did not do a run with no intake connected. I would love to go back in time to do such a run to rule out the intake. It would have also been good to do a run with the airbox lid off. There's a test there where increased IAT vs more available air could be a positive tradeoff. I remember taking the lid off my R34 Turbo setup back in the day and noticing a monster increase, even if IAT's did go up. Could be similar. Hard to test unless I find a very deserted road.

Had a chat to Tony Mamo - he advised that looking at the graph's shape (regardless of number translation) it shouldn't be levelling off like that up top. He said it looks like the car is running a restrictor plate or something of that nature. Luckily the last dyno pull on E85 was saved to the PC - So I did a quick trace of Barometric KPA vs Intake manifold pressure, and lo and behold I see a copy of the 'waves' I was seeing on the dyno: I'm not entirely sure how to go about addressing this. It may be worth sacrificing IAT to run a more direct intake for the motor. Though packaging this could be flat out impossible given the constraints of the car. I should have removed the intake pipe to see if this made a difference but looking at this graph I now have something to potentially test in the future and think about. This one is from an old track day log in the OLD setup going through gears on track.

Well, I'm tired. I'm tired because about 4PM yesterday, before today's appointment someone immediately bought my bumper. They couldn't get it any other day as they're on the way back to NSW. So I had to do that big GTR conversion I had been planning. Unfortunately, the information on SAU about what you need and how this is done is incomplete. So what should be a simple bolt on affair, yeah, it's not. Did you know if you use all GTR items the bonnet won't close? This little manuever sent me into about 1am the night before trying to dodge a way to get it closed. I will have to revisit this in the next few days - or maybe not, I may let a body shop figure it out. It all needs to come up and my motivation to pull the bumper off is low. It also seems to hit things in the bay where the GTT bonnet didn't. Yes I used 100% new OEM GTR items. Today, I had the joy of driving to the dyno looking like this: Given I had roughed in the fuel and given sensible but pretty conservative timing, I didn't really bet on having the car drive out any real difference than when it drove in. Sadly due to a miscommunication and laptop fun and games (and almost bricking the dongle, prayers and firmware updates indeed), I ended up using HP Tuner credits to licence the car that was already licenced. So in the end my laptop was used. It turns out my butt dyno is still well calibrated after all this time. The 325kw was on 74% Ethanol, the 313kw line was on 98. The other line is the 'before' line which was 281kw. While the numbers are pretty low, they're pretty in line with what you'd expect. Even if US dynos bump the whole result up about 50KW, gaining 10-15% is similar gains. The curve of the cam is pretty much spot on with what was discussed as well. All this said, it still feels bad to not see the number you secretly want to see. Even if the car drove great beforehand, and I knew pretty confidently the car would drive out much the same way it drove in due to the nature of a wellish dialled in LS1 not gaining much if anything at all from being tuned from where it was. As expected, the car isn't particularly sensitive to running it at anywhere between 12.0 and 13.0 - And the initial timing at 20deg and 12.0 made 308KW. So 3 degrees of timing, and leaning it out to 12.7 for 5kw, anything above stopped giving any benefit until E85 (which has an additional 2 deg as before). Car itself behaved entirely fine. I found out that 100C = 1.15V! IAT at about 7pm was 19C. I might mess with the bonnet mounting.. but given the REO NEEDS TO BE CHOPPED TO FIT A GTR BAR this is possibly something I may leave gathering (more) dust until it returns to paint jail.

I guess when I say it's a POS I mean.. the solution and the stuff has the capacity for maybe... 1 spot. You know, as a spot cleaner. What I really *want* is the ability to do an entire car, all upholstery, all carpet, mats, all seats, door card inserts, A pillars, roof liners, etc. In one go. I get lured by all the jank that comes out and think "I'd like to be able to clean to that degree"

I got a hand held bisssel one and it's a piece of shit. Doesn't work for more than about 5 seconds. So much so that I nearly refuse to believe any wet dry vac actually works or has enough suction to clean the carpet of a car. I'm discouraged as all the good ones are $300+ for an unknown result. I saw MCM did a Ryobi video where they use this thing: https://www.ryobi.com.au/products/stick-vacuum-cleaners/18v-one-hptm-brushless-spot-cleaner-tool-only Anyone have any experience actually using a tool like this when not paid to showcase it?

That could very well be the thermistor, but the ECU only sees Volts. VDO don't seem to provide a 0-5 volt curve, only the resistance curve.... (or line).

I already have the ability to datalog the voltage... what I can't do is correlate it to what the gauge is showing when I'm looking at the data at a later date. Or something like this. Except getting the oil to 125C+ involves me going 200+kmh at the track so you can imagine this is a little tricky unless I do something like note what the voltage is when I am at the top of 5th gear so I have a point to reference on. Drove car today. O2 still reading richer because hopefully not a leak instead of massive restriction I've introduced. Car really doesn't sound like a LS. It's quite strange. Pulled a bit of fuel out up top. This does potentially explain why my spark plugs looked like the car was running pretty over-rich. If I was tuning it to a ~12.7 which in reality was far richer than that in the past. It will be handy to have the dyno WB to compare my WB to to compare notes that's for sure. At this point I'm happy to just sit in the passenger seat and tune the thing given I've got about 7 million hours on the platform lol.

Yeah - Half the problem is I know this sensor actually goes to 150C.. I'm pretty certain it is min of 11C. So still more data required I suppose. It's really quite hard to get the oil temp to 100+ then immediately pull over and take a reading before the temp drops. Annoyingly I suppose the range I really 'want' is likely 80 -> 120C. TBH the ecu can't really *do* anything with it, and the gauge itself is very visible... ...but you know how it is.
