T04z On A 34gt-t

[Downforce]

you going for an internal gate or an external ?

I think the Plazmaman one might fit the 34s.....as it uses the standard runners.

Just need to find out of the runners are the same on 34s are they are for 33s.

Internal gate, HKS GT2835 Pro-S. Should tun nicely on the RB25 and be responsive enough to use on the track

Yeah I've seen the plenum kits sold by unique autosports.. but they are more expensive at $1500 than the GReddy ones! Plus they use the existing runners whereas the Greddy replaces the whole lot. For $1500 i could think of better things to spend it on.

Yeah thats the turbo Ive had my eye on for awhile....but im now weighing up the costs on getting the R version and getting a manifold and wastegate to suit.

Gary I'll look into that , a lot of people would be very inerested in an 86ARR T3 flanged exhaust housing for that turbine .

I'll be back , A .

[Binky1970]

I thought about the RB26 conversion, but couldn't justify the money when there already is a perfectly good engine in the car

I couldn't just use an normal RB26 anyway, i'd at least have to use an N1 or mabey even a Tomei engine.

[discopotato03]

HKS do kits for R32/33/34 2WD but can't find details of turbine housing ARR .

Nengun I think are advertising kits for RB's but won't let me in with Yahoo E mail .

The HKS USA site shows an SR20DET doing 300.6 TQ and Hp at the treads which sounds about the go . Yeah I know another SR 2L ally 4 .

Im outa here guys the trouble n strife and th tin lids are out and home brew awaits !

Chow for now , A .

hmm to sorta get back on track with the topic heading..

Just curious but with the added "benefits" of the NEO head...

when would a T04Z come on boost ? 5000rpm? more ? less?

[Binky1970]

My tuner said he would be able to get one to start boosting as low as 3500rpm.

[Morgs]

I think your tuner liked my turbo

I'd expect on a stock RB25 it wouldn't make full mumbo till at least 5k-5500rpm. Set of cams and cam timing may help to bring it up a bit quicker. Mine made 1 bar 4000-4500rpm on a built 26.

[discopotato03]

With a small enough turbine housing thats entitrely possible and .58's are around , HKS option a .61 for the TO4Z .

[R31Nismoid]

My tuner said he would be able to get one to start boosting as low as 3500rpm.

yeah, start making boost @ 3500... meaning 1psi.

You couldnt see anthing moderate 15psi+ till around the 5000rpm mark, give or take a couple rpm

Making boost and actually going somewhere are two different things.

You'll also be limited by the higher comp of the NEO

[Steve]

the larger the cams, the later the boost comes on but will give better flow (and power) once boost does come up.

If you want boost to come on earlier, try the smallest turbing AR that is available, port the head, and get the best flowing exhaust you can find - but definately not larger cams.

Sorry guys, but going back to the injector discussion on page 2, would GTR injectors be a good option for the 250-270rwkw range? They are top feed so they should fit sreight into the NEO correct? I have similar power goals in mind (270rwkw max) and was wondering if GTR injectors are a viable option for my power goal, as they flow 440cc. They can be bought for around $350 here in NZ, MUCH cheaper than the big name brands.

Hi Guys

I also have a R34 NEO, great thread on the turbo upgrade which I hope to do it in the near future. Need the $$$ first, working on the exterior mods atm. Btw, do we have to change the CPU as well if upgraded turbo?

[satanic]

I'm also in the game for a turbo upgrade this year... only thing holding me back now is a reliable and relatively cost-effective ECU option for the auto transmission

Once that is sorted then I guess the GT-RS is a good option (or at least something similiar).

GCG Hi-Flow option seems to get a good wrap around here as well...

Yes I can see that :lol: that's a mighty fine looking GT-R badge you have there... nice GTT though
