m20b25 with b27 head

[e30m20beast]

regardless of it fitting, the eta head is a pile of shit for making power. It's good for fuel economy and that's about it. It would be a downgrade, you already have the best M20 head.

for what I know the only thing that it will help it is making the compression higher.

b25 block with a b27 head would = higher compression , but the top of the piston would hit the head. besides whats the point lower reving?

ok I undersand what you people are saying, I don't know how or what the guy did to fit it in, I was just asking if it was a pain to put it in or you could do it just like a bolt it in thing. I also will like to know what are some "cheap" things to give power to the m20b25, I am low on budget I will be able to spend like $500 on it for now and my friend is a mechanic so I don't need to pay for help.

What I have done so far:
1.K&N drop in filter
2.Custom made exhaust (2.5" all the way back with high flow cat)
3.Grounding wires kit (a friend from BMW dealer ship told me reference points on where to put the wires)

You just need to stop, friend. You're embarrassing yourself.

it won't fit anyway. the pistons will hit the head.

but he's SEEN IT DONE!!!

higher compression until you crank it over, smash into the head and bend a rod or worse. ;)

^ Exactly.

What you've seen is the 2.7 ETA block with the 2.5 "i" head, intake, TB, ect ect...

If you've seen the 2.7 ETA head on a 2.5 "i" block, you've seen a broken engine.

That's like intentionally creating a bottle neck in the system...

The short answer is no. There's nothing to be gained from mating a B27 head with a B25 block.

[e30m20beast]

no I meant B25 block with the B27 head, I know some people do it without doing anything to the block( I have seen it)

[e30trooper]

yea i think he means 2.7i lol

[Wishno87]

I think you mean B27 block with B25 head
