As of later this week I’ll be the proud owner of a 95" R33 GTS25t, during ownership I am looking to only spend around $2000 on mods. At the moment the only non-stock parts are the 3" exhaust, air intake and BOV, I'm not sure what to invest in next.

After doing a bit of reading it seems that if new PartA is installed it can put additional pressure on Partb meaning you need a new PartC, so I’m a little confused. I should note that 80% of my driving is freeway driving.

It looks like most people don’t recommend running the stock turbo over 12psi, if mine was upped to 10-11psi what mods should be added to accommodate this increase with a $2000 budget? Where does a newbie start, second hand FMIC?

Any help here would be great here too!

Cheers

Shane

with the exhaust you are probably running about 9-10psi already, so a bleed vavle by itself isnt going to do huge amounts.

first thing I would be doing is getting some decent suspension - probably cost you around 1-1.2k for decent second hand. Some caster bushes cost you about $200. Next would depend on how far you intend going with the mods. A SAFC (SAFC II new from greenline is about $425+ postage) isnt a bad thing, but if you intend going for > 200rwkw, a full management system is better. you could get a SAFC fitted and close to tuned with the change from the 2k after the suspension.

After this is done, then be thinking about cooler and bleed valve. Also good cheap mods are strut brace and pineapples. Swaybars are good too, and about $500 for adjustable selby's front and rear. Building a cold air partion is a very cheap exercise, and helps keep the throttle response crisper once the engine has warmed up.

A second hand cooler is ok if you find a good one, but you wont be able to find both cooler and suspenion for the $$$ i think.

this is one option.

you could go cooler and SAFC - but it really is worth getting suspension sorted - make the whole driving experience alot nicer :P

Some thoughts anyways.

Thanks for you reply Steve, shes already got Aftermarket Lowered Suspension and Front Bar.

Getting a cold air intake partition was in theb ack of my mind.

So it looks like Management system and IC are the next step...

Is there an abbreviations page somewhere in the FAQ? SAFC?

SAFC = Super Air Flow Controller, basically an interceptor that tricks the ECU to allow tuning of the air/fuel ratios. Most people seem to report 20-30+rwkw improvment with the fitting of one of these. With one of these and a cooler, you could expect a dramatic improvement in the performance of the car, $50 for a bleed valve (dont go over 12psi for reliability sake, or 10psi with stock cooler). Probably be in the 180-200rwkw range.

Providing everything is in good working order, i would get the sway bars (assume your bushes etc are in good order... if not replace them at this time)

with the remaining $1500 i would look at an intercooler kit. With your current exhaust, filter and a new IC you will find boost is up around 12psi without any boost controller.

Your car sounds pretty much like mine did when I first bought mine, this is what I did:

Hybrid Intercooler $705 (I did my own piping)

Profec B EBC (used) $450

SAFC fitted & tuned $650

Pineapples $95

TOTAL $1900, 188rwkw@12psi, since then I've added a dump/front pipe ($230) as I only had cat back exhaust but haven't had the SAFC retuned yet.

The 13.4second thread and the project 12second... threads start with some ideas that will come under your budget given you have a full exhaust.

The intercooler change is good when you intend a larger turbo and all the rest of the expense that goes along with it. That alone will eat up all your funds.

A light flywheel and strong clutch (if it's a stocker) are good little budget mods.

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
