Gcg Highflow R33 Build

[pshht]

Im at the point where i want to upgrade my turbo and considering the success had with the gcg highflow turbo thats the way i want to go. Ive read the threads on rb25 turbo upgrade but just want to ask a few questions.

Basically what other mods do i need to do to get the full potential of the turbo?

So far i have:

Pod Filter

Turbo Back Exhaust

Blitz Dual SBC Spec S

Power FC

+ the usual suspension, brakes, clutch mods that have been done.

From what ive seen this turbo is good for 250rwkw to 270rwkw?So i just want to get the right parts for this power output..

I plan on getting:

Hybrid FMIC (600x300x76)

Bosch 040 Fuel Pump

Things im not sure about are:

Injectors, what brand, size, etc?

Z32 AFM is it needed?

Thats pretty much it i think, im just after your opinions and suggestions

Cheers

if you want just ~210 odd rwkw you should be fine with the stock injectors and afm. otherwise, the mods you've listed are more than suitable.

if you want more, some 550cc injectors will help and maybe consider a FMIC that flows a bit better, if you are spending 2k on a turbo to make the power, dont just spend $450 on a full intercooler kit. Get one of the Blitz/Trust intercooler kits.

Your on the right track there mate to get the full potential.

- injectors, JDM manual S15 480cc are probably your cheepest option but may be hard to come by. Nismo ones from www.nengun.com are a direct fit 555cc will be plenty big enough and easier to tune than the 740cc's

- I highly recomend the Z32 AFM for a smoother tune

- cams will help also the tomei poncams are proven performers you can get them from www.nengun.com.

- I think the hybrid or copy cooler will be plenty good enough

With the above mods 250rwkw is achievible maybe more but its better to aim lower with your expetations.

Also do a search for threads by sydneykid and gcg highflow

cheers

Thanks for the help guys i appreciate it..

Well im pretty much sold on the hybrid cooler just for the price and opinion of others who have them.

Also i didnt realise the bosch 044 can be mounted in-tank so im now going that route.

As for injectors ill go with 550/555 (depending on brand) just looking around for the cheapest price/good brand, etc.

Z32 sounds the way to go..

But as far as turbo choice, im stuck between the gcg highflow (450hp) or a GT30 which is internally gated and has a rear housing to suit the rb25. These are both the same price but the catch is the gt30 needs oil and water lines to be changed around. Anyone have a suggestion here?

All depends on what u want...

A mate may be able to help you on here, he made 330rwhp with stock injectors and is getting a proper tune soon! Gcg hi-flows are good on rb20s and awsome on rb25s

You can always go a vg30 exhaust housing if u was searchin for more lag/power down the road with the turbo too! Lots of options

[pshht]

the vg30 rear housing gives 450hp i think so thats one option i was thinking of
