cinq turbo owners...

After deciding to keep my car and not sell it, I'm going to go ahead and fit the turbo I bought for it (I think).

The thing is, I keep hearing different stories about the engine. Some people say the turbo will go on no problem, and others say it will blow it to bits unless I get the pistons skimmed to lower the compression. I've got an intercooler for it, and I've been told fitting the turbo without the intercooler will be safe enough.

So what I'm asking is, all the cinq turbo owners out there, have you done anything to the engine like piston skimming etc. or did you just wack the turbo on?

I feel a 1242 turbo coming on...

Oh yeah, I'm running a punto 1242 engine if that makes any difference?

If you drop the boost to 0.3 bar you won't need to skim the pistons. At 0.6 or so (which is what yours is set to) you will. If you have the intercooler, I'd fit that anyway as it'll reduce the heat of the air going into the engine and reduce the chance of detonation or melting. Also, cooler air helps make more bhp as it's more dense - it contains more oxygen.

High boost pressure on an unmodified cento engine is a recipe for meltdown.

IMO fitting the intercooler will be vital to get the most out of the Cinq at a relatively low bar.

If the air supplied to the turbo is warm/hot, you wont be getting the full potential. You've spent a few squid getting this far, so fit the damn intercooler! :D

Another day...another problem...

so how exactly do I go about lowering the boost of the turbo? At the end of the day I don't want Subaru Impreza beating performance. I'd rather sacrifice a bit of power and not blow my engine.

Have the wastegate pressure setting adjusted - needs to be done on a rolling road by someone who knows their stuff, also they have to have a boost gauge attached. It'll need rolling roading anyway to set up the fuelling.
