you will need a set of grey injectors or siemens for 400bhp .
if you getting cr turbos to do rebuild on turbo you could get them to do t38 turbo if you want abit more power later on.
hope this helps ,im sure someone else will give you some info

would the t38 not make it a lag monster though
on standard internals?

Shouldn't be any worse the the T34.63

Will also be a lot more reliable at the power you are after

some people would say yes and some no

some people love the t38 but some say go for a gt sieres

ive got a t34.63 on mine and with greens /3bar/rs500 intercooler and at 25psi it made 335bhp with 363 torque and very drivable .ive spoke to a few tuners and said blue injectors and more boost would make a very nice 370-380bhp as next stage up .

speak to SCS/MAD or one of tuners on here and see what they think

If its getting a cr turbos re build then ask them to spec it to the t38 like already said..
With std cr albiet valve pockets and a bd 14 inlet and a bit of head work will see some good results and at less boost than the t34 will see circa 420-430 hp and around 400lb ft no probs..

As for injectors id go with siemens 55 lbers and once all finished to get the best from it all alive map..


cheers danny
Or a AB07 Inlet cam if you don't have valve cutouts

"whilst the T34 will give you power to around 380bhp"

So i would say... no 380 bhp from the T34 would be my best guess.

Yes but that probably means with the smallest exhaust housing (.48)?

Tbh Marty a T34 even with a .63 will struggle to do a genuine 400 imo and if it does it WON'T last long...

I just don't see the point in ringing it's neck with boost to get 400 when a GT3071/T38 will do it with ease and be safer...

+1

Why buy something that wont be what you want and have to buy a better one next time and brake this one, might as well save up for it or go for less power like 350-370 bhp as i think it is a big step up from 300.

thanks for the advice peeps
engine as far as i know has not had a rebuild the car has covered 66k genuine miles with full history to back this up. i do about 2k a year in her
no signs of any blue smoke or rattles yet lol.
i had a stage 3 saph 7yrs ago that was 350bhp with 362lbt.
so the step up from 300bhp wont be a problem
just after a genuine 400bhp cossie and while im doin the turbo
may aswell go t38.
i intend on getting the car re mapped just got to collect all the parts in.
cheers

Don't bother they will be maxed out and ruin the setup - go straight for the 83's

Get some 72lbs like mine, a nice in between..

But as Danny said, i thought 55s flowed enough for 400+

My 55Ib were maxed safe at 441 - should have never gone down that route with a bigger than a T34.63 turbo

just fit 83lbs as then you wont max them out and room from more in the future and they are the same price anyway so its a no brainer

of course its possible reliably - my moonstoner 3dr was 400bhp/lbft and that was reliable - as long as the turbo was rebuilt every 18 months.

Inlet was Mountune K2 inlet cam, ported and polished head running motorsport 400 blue injectors.

This was on a harvey gibbs engine - never even had to open it up either and it did a few trackdays and used to love hitting the limiter

So a Turbo build every 18 months you'd call reliable Ran??

Depends how much use/mileage its had in 18 months.

I've seen turbos fail within a month when pushed really hard, a T34 does seem to take it ! or I should say my mates did for the whole time he owned it which must of been 5 years !
