R34 Question

[Binky1970]

I'm just about to have a Blitz SBC i-D III put into my car and am wondering what sort of boost i'll be able to run without killing the engine or sending the ECU into panic mode.

My car is a 99 R34 GT-t

FMIC

3" turbo back exhaust, 3" high flow cat

K&N panel filter

The rest of the car is absolutely stockers.

Would I be able to run 9-10 PSI without needing new fuel pump, etc ??

Would it be alright to have 12 PSI as the high setting to be used every now and then ?

[Abo Bob]

I think so.

[Binky1970]

OK, cool.

New question. At what stage do I need to upgrade the fuel pump ? Also would it be worth while replacing the stock BOV with a GFB/Turbosmart pumb back one ?

cheers

[NJR 34GTT]

BOV replacement will do nothing. Stock item is fine.

[Bass Junky]

I run 0.8 bar all day everyday. No problem.

I have a PFC and PFC Boost kit.

do not repeat DO NOT get a GFB one..........had one on mine and the thing only lasted just over a year. The O ring seal came off and got stuck in the valve.

But as NJR 34GTT said the stock one is fine...if you must change than get a Greddy item and plum it back.

[Binky1970]

I've seen the Greddy Type S ones cheap as they are now a superseded model but i'd rather spend the money on something that would be more use.

what sort of work have you done to the engine in your 34 Sho ?

[shonen]

not that much...just the basics so far.......still saving up for turbo.

after the GFB one karked it I bought the new Type RS.....very nice....still waiting for the plumb back adapter to arrive but yes so far so good.

[Binky1970]

which turbo are you going for ?? I have been offered a really good price on a slightly used Trust TD05 turbo but I'm not sure what its going to be like on the car.

[Abo Bob]

You have to change a bunch of stuff to fit that turbo. Manifold, dump, etc.

Fuel pump needs to be changed definitely with turbo change but possibly before then depending on what you are doing. You wouldn't want to push anymore than about 190-200rwkw without changing the fuel pump.

Shonen is going for the biggest turbo known to man. It will be henceforth known as the Shonen Potato.

Which TD-05 is it? 8cm or 10cm wheel?

[Binky1970]

I'm pretty sure its the 8cm, but it is possible i could be wrong. I'm not sure on how all the numbers and shit that go with the turbo works, but would hte TD05 be considered a laggy turbo on a NEO engine ?? I'm not chasing big power in my car so i'm looking for a turbo that spools around 3000rpm and doesn't really run out of puff til somewhere after 6500rpm i guess.
