Hi,

i want put a bigger turbo or hi flow the stock one? Which is better as i dont wanna change internals but want my engine not to blow or fry a piston. What is the best turbo for minimal lag, most power and a good amount of power at the wheels with standard RB25DET.

thanks

If you're after response and good average power across the rev range, then I'd recommend a highflow - good bang for buck and should easily see 220-250rwkw with the right supporting mods.

If you have enough coin and are after more power whilst still maintaining decent response, then the HKS GT2835 ProS is also a good choice.

pfc + 740cc injectors + z32 + HKS GT2835 PRO S

Isn't 740cc overkill for anything under 350rwkw? 550cc injectors should be more than adequate.

Depends on how much power your after mate? and whether or not you may want more power in the future again!

again it depends on your supporting mods as well. sooner or later your going to need to change ur fuel pump, injectors, clutch, ecu...etc...and all of which costs more money.

imo, i'd go a HIFLOW. the hiflowed turbo will give you the best of both worlds, more power than stock and pretty good response as well. and best bang for buck!

my two cents,

goodluck mate

i would recommend the gcg hiflow, i had one of them on my rb25, got a vg30 ehxaust housing adapted to it and results were very good, i was more than happy with it. made 258kw at wheels on 15psi, my engine is built however but still expect a signifigant gain over standard turbo.

I'd go for a GCG highflow turbo. Personally tried and tested. Close to stock spool time, but huge power. It's ball bearing.

Bolts striaght up. No modding lines etc. Includes everythign you need e.g. gaskets, washers, etc etc.

Cheap -- 1750.

The precision turbo highflows in the group buy section are also good - 1550. ball bearing too. I personally haven't tested them, but I know people who have, and i'd get one.

      Pads for R32 GTS-t, R32 GT-R non V-Spec (Sumitomo), R33 GTS-t and R34 GT-t are all interchangeable. R34 GT uses a 2x piston caliper, hence it didn't fit.

      Checked with amayama and nope, the full S2 manual set is not available anymore. Unsurprising, but still disappointing as the ? on availability gave a glimmer of hope.

      I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
