Kinkstaah

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.

I think the concept is highlighting the various scenarios where thicker oil helps, and thicker oil potentially doesn't help and only generates heat and costs power, in turn for safety which isn't actually any safer (unless you're going real hot). If anything this does highlight why throwing Castrol 10w-60 for your track days is always a solid, safe bet.

I don't think there's any way someone is push starting this car.. I honestly can barely move it, and moving it and steering it is just flat out not possible. I'm sure it is, but needs a bigger man than me. I have a refurbished starter now. The starter man was quite clear and consise showing me how nothing inside a starter really should contribute to slow cranking, and turned out that for the most part... my starter was entirely fine. Still, some of the wear items were replaced and luckily it didn't show any signs of getting too hot, being unfit for use, etc. Which is 'good'. I also noticed the starter definitely sounded different, which is a bit odd considering nothing should have really changed there.... Removed and refit, and we'll pretend one of the manifold bolts didn't fully tighten up and is only "pretty" tight. GM only wants 18ft/lb anyway. I also found a way to properly get my analog wideband reading very slightly leaner than the serial wideband. There's Greg related reasons for this. The serial output is the absolute source of truth, but it is a total asshole to actually stay connected and needs a laptop. The analog input does not, and works with standalone datalogging. Previously the analog input read slightly richer, but if I am aiming at 12.7 I do not want one of the widebands to be saying 12.7 when the source of truth is 13.0. Now the source of truth will be 12.65 and the Analog Wideband will read 12.7. So when I tune to 12.7 it'll be ever so slightly safer. While messing with all of this and idling extensively I can confirm my car seems to restart better while hot now. I did add an old Skyline battery cable between the head and the body though, though now I really realise I should have chosen the frame. Maybe that's a future job. The internet would have you believe that this is caused by bad grounds. In finding out where my grounds actually were I found out the engine bay battery post actually goes to the engine, as well as a seperate one (from the post) to the body of the car. So now there's a third one making the Grounding Triangle which is now a thing. I also from extensive idling have this graph. Temperature (°C) Voltage (V) 85 1.59 80 1.74 75 1.94 70 2.1 65 2.33 60 2.56 55 2.78 50 2.98 45 3.23 40 3.51 35 3.75 30 4.00 Plotted it looks like this. Which is actually... pretty linear? I have not actually put the formula into HPTuners. I will have to re-engage brain and/or re-engage the people who wanted more data to magically do it for me. Tune should be good for the 30th!

Welp, I have been driving it around (a bit) and messing with idle and return to idle characteristics. This is all well and good until I discovered my starter motor... is nearly dead. This is unfortunately after I booked my exhaust and tune in. This is the new section of my exhaust, after losing my mind with vbands and clamps. Yes I now have 4 mufflers. The two middle ones are 5in body 3in pipe round straight through mufflers or incorrectly named 'resonators' whatever you want to call. How does it sound? Muffled. Car runs richer now in low load. Is it restriction? Or lack of exhaust leaks. I also figured out a way to make the Analog Readout match the serial WB Readout. All of this requires a car to you know.. *start* to tune the maths, which was not ideal when I needed it to get to the exhaust shop and back. It started when cold. 30 mins after the car got home, it was time to get stuck into it. Unfortunately this thing has no identifying marks on it at all. I contacted Mal Wood and asked if he could send me a replacement and he asked me to remove it because they've changed starters with their kits a few times over the years. I asked other companies with LH LS starter conversions and they all use different starters unique to their kits. I did find CAE performance supply Mal Wood - But they are out of stock for this starter for the next 3 weeks. The tune is booked for Friday 30th. Here's hoping the local starter motor repair place (which interestingly has a 5 star review from Trent @ Chequered) can get this rebuilt/sorted out so I can get it on and put the car on the dyno. Here's hoping!

I mean, the 240i is not a Supra... make it drop a few hundred kg, have a sportscar chassis, clearance for wheels etc... Maybe I want a hardtop Z40i XDrive or something :p I do agree with you though and have long said the B58 Supra/240i/340i/440i is the new R Chassis/JDM90's turbo rocket for mod lovers to ... not always appreciative response lol. Doesn't make it not true though.

AWD MK5 Supra when?

You sweet summer child, if only you knew the intricacies of the world of LS you would come around to the lego construction of them and truly praise the LS1, the greatest of all. This of course depends on your use case. That said, LS7 is actually down towards the bottom of the list. The amount of info on the subject puts SAU's 20 year knowledgebase on RB's and R chassis to shame.

Fuel use with a LS is about the same as a RB. Slightly better than a modified RB with a responsive turbo. :p You'd need another excuse to not go LS (there is no excuse to not go LS)

these are not the same

All motors are consumables. This thing costs $250,000-500,000 and makes 640hp/430 KW, naturally asipirated. It has a competitive advantage in being more reliable than other cars it competes against. They rate these engines in hours before rebuilds. Are you going to out-engineer half million GT3 car manufacturers in a garage? People really need to be honest with what they are going to do, and remember that 99.9% of the people on the internet are not honest with how they use their car and what it holds up to and how much power it makes and how easy/hard it was. Anyone worrying about the block limit of anything is the kind of person that will be unable to do a single track day, for example, perhaps not even a single session. Build the kind of car you would want to have if you could never tell a single soul about it and nobody would ever know.

I'd leave the series 2 bumper on there. Anything else is gonna be a bit janky TBH :p (or at least keep it)
