You know what "thought" did!

 

STI V7 has the forged pistons STI V8 unfortunately hasn't.400bhp still should be ok.

 

So we are getting conflicting information again, it has been stated on this forum before by a top tuner that the ver8 engines have forged internal.

 

where has anyone said there not or that they are?

 

I have read a previous thread discussing this (few months ago) and Paul from Zen confirmed they are forged on a ver8.

 

it hasd been posted above and I missed it

 

will have to search back for the thread.

 

If 400 to 450 bhp was the limit on a version 8 sti,
what is the torque limit?? 400ft/lbs

what would need changed for a safe 450/450,
pistons and rods only?
Any idea what would this cost from a reliable tuner?

 

Pistons initially.... followed by the rod's if you wanted to rev up to the full 8200rpm rev limit for the JDM varietys.

 

You could stroke the engine while it is out for reasonable money, we are currently selling a package utilising your block, a new 2.5 crank,forged rods and pistons built ready to pop your heads on for £1700.
This would be good for 600hp+.

 

I stroke my engine every day.

Sounds like a bargain Martyn - how strong are the liners in there, will the block cope with 600 bhp+ ?

 

and you say I can be strange.

 

No, JD - I said you are strange

 

pot kettle black.

 

Wouldn't expect to have liner issues on 2 litre cars Duncan, of course it is all down to turbo choice and pressure levels.
Choosing a turbo that will support your power goals at a sensible boost level instead of running 2.5bar plus is a good idea.
This set up will certainly take all a T can throw at it.

 

what does it stroke it to 2.1?
