Hi

Im collecting parts for my turbo build (M20B25)- can someone advise me which headgasket to get (mls or decompression plate maybe?), where to get it, where to get arp bolts, and which intercooler will fit behind the valance and grill with a car which already has a/c as well.

I would like around 400bhp and will probably be looking at vems as well

standard head gasket will be fine as long as you have the later low comp engine
arps best place is the states as there expensive over here
as for intercooler that's up to you just measure In between your chassis rails
get a tape measure out and measure it

+1 for standard gaskets!!! works fine on mine. you'd be surprised at the size of cooler you can fit in there too.

i have a h reg (91) 325 and looking at puttting a turbo on, after seeing the bit about later engines the head gasket should take a turbo. would mine be ok. thanks.

yes just get some arps to keep the head down but
always check the engine code tho first a mate of mine assumed the same but was actually an early high comp engine it will have 25 6 k for a low comp and 25 6e for a high comp

Ok, cool. Thanks

I have had the head skimmed though I forgot about that.

shouldn't make to
much of a difference
