I've gotta send Harvey my GT28 cause its died for some strange reason after just 4k miles Thing is, if it gets replaced under warranty then thats fine but if not and I've gotta buy a new turbo, then I'm thinking of going to the next stage, my basic engine spec is:

low comp 7.5:1
long studded
polished and ported head
ahmed inlet cam, std exhaust cam
WRC triple layer head gasket
Grey's
radtec 500 cooler and alloy rad
air 2 air
blah de blah

was running 1.9bar on the GT28 with approx 400BHP

How much are GT30's, can they be used without external wastegate?

How many extra ponies do you think in conjunction with my spec engine?? I was thinking 430BHP????

cheeRS

 

T38 mate..

440 at 26-28 psi !

 

400 from a GT28, thats no mean feat!

At that level i would go for the GT30 instead, or the GT3071R or something like that.

Cost is about a grand.


430 sound reasonable enough to me.

 

No idea, but, are you using a d/v ? If not, that could be the reason it died so quickly, Simon (SECS) had similar problems IIRC.

 

yes mate, allways used a dump valve

 

Scott - you will need to change the cam's if you go for the gt30 mate cause those in your car are same as mine - good for t34 - crap for anything bigger.

 

fook! will have to speak to Harvey if this warranty claim gets thrown out about which direction to go in

 

DIng - are cams too lairy for a bigger turbo?

 

Nope mate - standard zorst

 

i ordered a GT30 from AET last week (with -31 & internal wastegate)
the better model retails at £1200+vat.

 

the courier just delivered it, it looks the nuts

 

sav a look then lad

 

i'm selling a GT30 (external wastegate one) for £1250 ono..

 

Well the Harvey GT28 is nothing like a "real" GT28, its more like a flashy version of a T34

 

400 horses out of T-34 on pump gas is a feat too isn't it?

 

i just in, i'll do some pics shortly

 

errrrr NO !

come to England mate, loads of T34 400BHP motors over here

 

I remember Mike Rainbird saying not long ago that octane ratings of petrol are dropping so bad that it's becoming very hard to achieve that levels with such a small turbo.

Still levels of Ford tuning I can see here are amazing to me. My car is considered by some a VERY VERY fast car here in Poland, it's very slow in England :-/ It's only problem of money though.

I will have fast one one day

 

just bring it over here to get done mate

 

The first thing I do when I win a lotery or something....

 

 

you git



Thats awesome

 

Its for the fiesta

 

i'm liking the look of that mate

 

Reyland Motorsport

GT30 is £895+vat

http://www.reyland.co.uk/Parts.asp?ID=2

 

GUZZLER, what size e/h is that? the wallet is burning a hole in my pockets bet you wish youd paid 895 + vat

 

when i ordered there was a few differant versions, i wanted the top of the range one as it needs to be able to cope with around 550bhp, hence i went for the top one, not the budget version

 

.8 A/r compressor holy shit! what is the exhaust A/r ?
cadbury's caramel style 400+ bhp at 1.5bar

 

GUZZLER, the differences being what?

 

400bhp from a t34

Only on the dyno not in real life LOL....

 

Fair play thats the bollocks

BUT you got to realise, like the Harvey GT28, its not a normal/official GT30, its AETs version, nothing like a normal one.

Looks the bollocks tho

You wait till you hear the fookin row that thing will make when spooling up with that ported shroud inlet- will sound like a fookin jet engine

 

steve, explain?

 

Actually, semi-ignore me I was thinking of a different turbo

Compressor side its 100% GT30R, but the exhaust housing is a cossie fitment one (.63 EscCossie or RS500? Not sure) rahter than the usual GT30R hosing with the 4 bolt outlet.

Can only presume exhast wheel is a proper GT30R one, ie 60mm 84 trim

What a/r housing is it? GT30Rs come in .63 .82 1.06 but as that looks like a actual cossie ex housing im guessing .63

Leecavturbo-- Its .60 a/r, not a .80!

 

Itsmeagain, The exhaust housing is a custom cast unit for internal gate the rest is pure Garrett, Mad ade,s 185mph car has this unit on.

Mark

 

That Turbo does look the tits tho!

 

strange my GT2540r is .7 A/r so i just presumed it would be bigger

.

 

Lee, A/R ratio isnt relative to an actual size, ie a .70 isnt necicerily bigger than a .60.

For example, a GT40R has a .58 a/r compressor and is fuckloads bigger than than your one.

 

nice turbo...

 

What would cause your gt28 to die after 4k miles though??

 

you tell me mate, its not just the turbo thats done 4k miles, the engine has had a full rebuild too.................Harveys gonna investigate when I send him the blower
