Dont golds only work with FRM, something to do wih matched expansion rates of the material to that of the bore?

What is FRM ?

FRM is fibre reinforced material which is a low friction coating that is put on the h22 engine sleeve. It gives the h22 low friction and wear but what it does mean is that a 'normal' forged piston will chew up the bore as it would not expand at the same rate as the piston sleeves which was why a h22 block needed have cast iron sleeves before you can put a forged piston in the block. Before Mahle introduced the Gold Series piston....

I'm using a Turbonetics T3/T4 which is really responsive on the H22 and can make good power too. I'm sure that I have seen these turbos make well over 400bhp.

Injector wise I'm using the Mitsubishi DSM/eclipse 450cc injectors that fit pretty much straight on the h22, I'm not maxing out my injectors yet, not sure what duty cycle I am running though.

Well, you have saved me alot of money in sleeving the block

I'll start saving.... And I'll start a build thread soon.

Ive got a mate running 610bhp 24psi i think it was spent around £7k on it,

BUT thats in an eg civic.
Im aiming for 400 on stock internals for now, running at 0.5 Bar for daily and 1.0 bar on strip.

That too is in a civic eg as thats where the h belogs

Haha.

Im going to do it in a 5th gen prelude. Not many have been done in the UK!

Im aiming on high boost, to be at the 400bhp mark or close. So ill see what i need to do to achieve that. Other then that, its not that difficult to boost it. Ive been getting prices today on parts!

Once the block is sleeved mate its bullet prove and 400 is easy for it you can handle 700 once its done.
I spoke to a bloke on CL who gets a block sleeved by golden eagle £900 plus postage.

Which is a wicked price buddy
