Need help with compression
 

Hi all

I own a vauxhall/opel corsa dont know if any one knows of that car, my question is can I use a 2mm head spacer when I add boost which is in the means of a TDO5 turbo. The car is a 4 cylinder bore is 75mm and the stroke is 73,4 and piston displacement is 1297 quibic centimeters and lastly the compression ratio is 9:2:1. One of my friends told me it will definatly work but need to make 100% sure before so I dont break my car, thanks

I don't know what you mean by a head spacer, but if your compression is 9:1, just leave it, its plenty fine for boost

i think he means headgasket but that compression your at right now is very boost friendly. The higher the compression you go the more likely detonation will happen. Which BLOWS

9.2:1 compression is a very good ratio for boost.

ookay thanks 4 replying head spacer like a laser cut gasket but one that is 2mm thick and made out of god knows what, with a 2 normal head gasket on either side of the head spacerto drop the compression but you guys say that my compression ratio is all good for boost how much boost psi

It will work, but it's unnecessary.

And pics of your car would ne nice ;)

if your worried about parts breaking , leave it stock and dont finger ---- it ;)

Re: Need help with compression
 

"how much boost?" is 100% relative to the size of the turbo.

I would say that on an (approximately) 1.3 liter engine that a DSM T-25 would work nicely at about 10psi. Of course I know nothing of your engine, is it OHV or OHC? Fuel Injected or Carburated?
