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.

    • We have a huge update coming in the next few months, version 5 of Invision will be released. I'm holding off any changes until after this change as I'm not sure what features will be removed or introduced.
    • Yeah, plenty of air flow, there is a dedicated path that feeds the air in to the OEM intake tube behind the bumper As for a "tangible effect", maybe, but getting the pod/intake air out of the hot engine bay is worth it psychologically to me, even if it gives no performance difference, so the tangible effect in my Lizard brain saysss yessss  In the end, to me a tangible effect isn't always about performance, sometimes it a sound or a look, or even a...... feeling  Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga
    • yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching
    • Quite right, if you make it to that pension you deserve every cent
    • Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!
