Honest Turbo advise please...

[Billy_RS]

Ok, In my search for 380-400bhp in my 2wd saff im aiming for the following spec:

Standard 205 block and head recently rebuilt
BD14 Inlet Cam and Verniers
4x4 Inlet Plenum
Siemens 55lb Injectors
044 pump
Full 3" exhaust
Air filter
500 cooler
Ally rad


Now then, I was going for a T34.48 with a chip to suit...... BUT...... A friend of mine who broke his cossie a year ago has a GT30 and will let me have it for a decent price.

My question is... Will a GT30 be overkill for my spec, or will it do a job?

Cheers Billy

T34.63 housing. You would be better asking your tuner I would have thought.

GT3071?? GT3076??

Dont know that part yet mate

T38,gt30 is what you need a t34.63 will be maxing out at 400bhp and if your going to that extent go for a 200 block with valve cut pistons to get beefier cams in it

[iain]

for 380-400 running 55s id go for a rollered t34 for near 400bhp and the drive would be very good

That too far for me right now Craig. I just bought a house...

This sounds like what I have been planning. Roller bearing T34.63.

P.s, was your Cossie on the cover of fast ford Feb?

I had a T34.48 on my old spec engine, made 416 BHP and the drive was brilliant!! Loads of punch and not laggy!!

how many 100 miles did the turbo last

[Billy_RS]

How much REAL difference is there between .48 and .63 on a T34?

Lag? Boost? etc......

Anyway, with a Std 205 block, I wouldn´t go much over 400 bhp.

T34.55 IMO

I dont do loads of miles any way mate, but the turbo lasted for me and had no problems at all.. was running around 30-32 psi.

I then decided to go for more power, stuck a Gt30 on and cracked my block after a few miles

I am under the impression from other members on here a T34.63 (bigger than a .48) would max out at 400bhp Mike what was the rest of the spec mate

[turbomook]

Spec was 8 injector inlet, bd14 bd 8 cams, veriners, 200 low comp block, t34.48 and i have the rolling road print out to prove.. was mapped by bluesprint motorsports

Was it a long studded block?
