Spoke to AET recently about it, they seem to think they make 500+ on the correctly specced cosworth engine according to there dyno....

Hi Dunc
my gt30 is pulling hard at 3500 rpm i dont run much boost untill its live maped
ill give you the full S.P once karl ahs mapped it
for every chaseing big bhp on a GT 30 go for external version ,if not go for the internal
simple as robo chef

What controls the external wastegates? air injectors?

not sure on spool up time is quicker or not
my car is going on 1000cc injectors/late escort plelume /air injectors with a 12 postion boost controller /5 bar map sensor
see with myself one of the reasons i never went external wastegate was the screamer pipe that put me off , i do alot of track days and there has been a lot of cars that have been blackd flaged for noise because of the screamer pipe
what people have done to keep the noise down they have put a silencer on it or they have brought it into the exhaust system
some people recon when you bring the screamer into the exhaust system it loses a bit of power
i cant really give a full run down of the Gt30 external because i haven't had one
i went the easyway and i am not chasing big bhp either and the GT30 internal waste gate was the one for me
it is more expensive than the external one aswell

well this is interesting.i always thought that people steered clear of the gt range due to being fragile ?
i havent got a bloody clue on these,i know what a t3,t34 etc look like but the other week i was looking at a car that had a "gt28" on it,but it looked the same size etc as a gt30 i looked at on a car at nat day.
whats the difference?or is it all internal or is it the rear housing?

Its WANK.
THE END.
(Unless you are a Topspeed only knobjocky of course)
The GT30 is sooooooooooooooooooooooooooooooooooooooooooooooooo oooooooooooooooooooooooooooooooooooooooooooooooooo ooooooooooooooooooooooooooooooooooooooo much better its silly!
Its just a different car. Powerband is immense, third gear is STUPID on track!!! just leave it in that and drive it like a big go kart!
Ask Doug Stirling about his 4th gear trick on the road!

I think it's quite funny how people think that bolting a turbo on a car will be the miracle cure for a poorly specced engine .
My old T4 engine with a proper spec made 15psi at 3150 rpm and 32psi at 3500 .
It's not JUST the turbo, the whole engine has to be matched TOTALLY.

all madevelopments and autronic of course !
not sure of exhaust housing size

it feels like its trying to lift the car off the road !
go for it id say !

Hi Mike
i know what your saying , but what i am saying is bolting on a gt30 with internal wastesgate on my engine is 10 times better than the t34
my engine was supposed to be an exact copy of the harvy 400+bhp engine if it is or not ill will never know untill it striped
the only thing that have changed since fitting on the GT30 is the exhaust cam
it still uses the Bd** inlet
cam shhhhhhhhhh i shouldn't have said anything

My old spec was Farndon 82mm crank, standard rods, accralite short compression height 92 mm pistons (2,180cc), 7.54:1 c/r, medium port Nick Waples head, T4 mar-m 247 shafted 57 trim turbo, short duration cams timed in to bring the car on boost as early as possible, which meant that although it made peak power at 7k like a normal T4 engine, it dropped like a stone after that (where normally with long duration cams it would hold on to the power). The capacity would have only made a few hundred rpm difference, the most crucial part of deciding the powerband of a turbo engine is the cam spec / timing.
If you want a FULL detailed spec of my current engine, take a look on page 1 of my resto thread .

Remember a GT30 is not just reliant on the exhaust housing size. There are a number of different sized GT30 wheels as well. I now have the largest GT30 wheel on a .64 housing for my Cosworth Subaru Engine (turbo supplied by AET). Albeit on a 2.5ltr it acheives 525bhp / 525+lbft torque on straight pump fuel, with peak torque at 1.7bar and peak power at 1.6bar boost. With you Cossie boys..... thats pussy boost!
For a bolt on internally wastegated turbo they certainly seem to deliver.

If i were you, i should take Martin's spacer. Nice piece of work, and fits like a glove!!
Without, this is the problem.
The compressor housing hits the 2WD exhaust manifold.
