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.

    • New CAS just turned up from NZ Wiring. Looks like a nice bit of gear.  So, yeah. Triggered, bro. Realised I may as well do the cam belt while mucking about with it so will order one of them.
    • 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.
