Been selling my 53 Reg Astra Gsi Turbo for a while now with no luck

been offered plenty swaps p/x's (any1 interested pm me)

anyway, been offered a sierra cosworth plus cash

I do like sierras, but im in love with Escort Cosworths have been since i was a wee boy, but only 22 and still too young :s

this is the engine spec on the Sierra, havin been out of the ford scene for a while i'd like people view's on this spec, he's valued the car at £5500 worth it?

the guy claims 400bhp but im not sure,

any help/opinions much appreciated

its a white 2wd, 89 cosworth, lowered, 18" bk alloys, and quad lamps

200 4x4 block overboared 1mm,low compression pistons with large valve cut outs(91.775mm)
mlp heavily ported escort cosworth cylinder head with new guides
bd10 inlet and exhaust camshaft
4x4 inlet manifold with spacer plate fitted
3 inch bmw throttle body
t4 american spec xs power rx7 turbocharger with external wastegate (this spec of turbo capable of 650bhp)
both inlet and exhaust manifolds are port matched to cylinder head
tri metatic head gasket
403 grey injectors
stage 5 chip running at 1.5 bar boost
wrc spark plugs
scorpion exhaust system
L6 ecu
converted 4x4 engine loom
home made large breather system
4x4 flywheel with alcon 6 paddle clutch
pace rs500 intercooler
4x4 radiator

 

Might be around 400bhp with that spec. Theres alot of bad things said about the xs power turbo's, aka there crap and fail very quickly.

My car had a cheap ebay so called T4 on it when i bought it. The thing lasted 9days!!

Also how old is the engine and who built it? Who wrote the chip for it aswell?

 

As Nash has said really mate.

its highly possible that its a 400bhp engine.

but i would be cautious with the turbo.
personal prefference would say the BD10s will go in the bin.
spacer plate on inlet manifold wouldnt be needed at that power level and would possibly give a worst throttle response having it in there.
unsure why it would need a converted 4x4 wiring loom, especially when its still running a L6.
and a bmw throttle housing - why?

 

TPS diff and plug to main loom !!

 

i thought you only changed to a different TPS if you went L8 tho Paul.

 

ive heard bad news about the xs power turbo's before,

a mate had one on a 200sx, but which turbo would i go for? and how much would this cost?

im not adverse to a bit of work if the car is worth the asking price, the work was done by AVA in Scotland,

what cams to go for if not the bd10's?


im askin a lot of questions sorry, just want to make sure im getting the right thing

i appreciate the help

 

1mm overbore??, isnt that a little close to the mark for big power??

 

Depends what you call big power

 

absolutely right , in fact its the last chance saloon for that engine , no more after that and will fail very quickly at 22psi

 

so its a timebomb to an empty pocket/wallet/bank account?

 

would sound like it mate.

maybe not the best PX to be going for!

 

okay,

thank you for you help folks

 

i just wana say again in reply to cheap turbos there not all crap i gaurantee it. its just a matter of finding which ones are the good ones and i have

BUT the good ones i have found from america are only good for 400 hp maximum so cant comment on the turbo on this cos as i have never tried a cheap turbo of that size.
