Make sure you get a dyno run, and check your fuel pump is flowing enough juice in it's current form, and the car is making the power it should. I'd personally upgrade the fuel pump as one of your first mods. For a couple of hundred dollars, it could help prevent the car lean out, and will provide enough juice to support the mods you want to install.

I'd then do (in the following order):

- Turbo back exhaust (3inch - will be above the legal limit, but it's impossible to get a sports exhaust below the legal limit.. even stock WRXs are 89DB, the noise limit is 90DB). Go to your local exhaust shop for this. $1000 - $1500 depending on what you get

- Replacement air filter in standard airbox. You can order this online, or get your local Repco etc to order one in for your skyline. $100

- Front Mount inc piping. You can order this online. Price depends on what brand you want. Estimate about $1000 or so.

- Boost controller (turn it up to 12psi, on a dyno, to make sure it's running ok). Buy from most performance workshops, or order online. $100 for a T Piece mechanical controller.

- ECU (PowerFC). You can order this online from Japan to save some money, or just buy one second hand. You could just get a SAFC or something similar if you are on a budget. $1k for the PFC + ~$500 for tuning

Also invest in some good tyres to get traction.

This is too open ended of a question, you really need to specify a budget if you want exact answers and recommendations.

i wanna beat my mates silvia with sr20 inside. It has the exhaust and intercooler as mentioned above, and hks pod filter, its pretty darn fast. Dont mind spending, as long as i see him in the rear view, and 110% LEGAL.

LOL

this will end in tears!

if you want it legal.. dont change a thing. Even an engineers report will not stop you copping issues from the police.

You can try the obvious things first..

A. 10psi

B. Front Mount Intercooler

C. Full Exhaust

D. Aftermarket ECU

E. DRIVER TRAINING!

I dont know where you plan on racing your mate, if its at the track then you should get some training as its worth alot more than mods when it comes to a cars speed.

also learn how to launch properly, i mean its a bit hard to but u may snap a driveshaft who knows, launch like the japs put all pressure on the clutch and then let go, dont rev up and just pop the clutch, puts too much strain on the shaft, bring the clutch up to friction point before pop'n it :thumbsup:

u can chop his sr20 with just a few mods but uve got like 200kg more weight or so... but doubt with the mods he has he wont be able to pull more than 160rwkw but if u do it right for sure around 200rwkw just depends on tuning etc

On my old car I had a custom 3inch front/dump/cat with a 3inch Nismo cat-back and a 4inch nismo tip. I had my exhaust tested probably 10x in the 2.5yrs I had the car and never had an issue.

* K&N Panel Filter

* Turbo-back 3" Exhaust

* Bleed valve @ 10psi

* FMIC

* PowerFC

Cya in $5k's time.

    • I mean it's a bit late to say "This won't have any tangible effect and it is not worth spending more than about three seconds on it, please just enjoy the car" But I said it anyway. Does the pod actually get any airflow in that position behind a bumper like that?
    • Hey guys - apologies for digging this up. Has this website been shutdown or is the outage temporary?
    • So, went shopping at Just Jap for things that might work for the intake  After some trial fitting there I ended up with a 3" x 45° silicone bend, a 3" x 300mm alloy straight, and a humped joiner, some minor trimming will be required to shorten some of the stuff, but nothing that is beyond my "ham fisted" skills The guy at Just Jap was most helpful as we had all sorts of joiners,  bends and stuff out trial fitting  Laying it out above the stuff in there it seems everything will fit nicely, and looking at it, it is probably the way I should have been looking at doing it from the beginning, probably..... In the end it is a front bar off job anyway to remove the original stuff behind the front bar that is taking up the required realestate needed, so maybe a Thursday or Friday job And because I'm a hopeless consumer, I grabbed some new steel wheel nuts, the current ones are a spline drive type with a "security" socket, that somehow someone keeps misplacing, the new ones are a basic black steel 17mm hex socket In other news: I just did my "final" tax return, I am now officially a old retired veteran pensioner, and I'm milking the system for all it's worth,  life is good
    • I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!  
    • Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out
