1.8 turbo

[Vecken]

there is a good running DOHC 2.5L on craigslist right now, if you want to tackle the engine management system nightmare.

what nightmare? the 1.8 ecu will run it

EJ25D's are drop in, wont make full power from what I was told but you will have more. I have yet to find the displacement of 1.8 heads compared to 2.2 heads. With those numbers a compression ratio bump could be determined. I believe I ran some assumed numbers which ended up with roughly 140 hp at the crank for a 2.2 with 1.8 heads. Could be more but who knows.

2.5 with 2.5 heads only puts out 160ish.

140 for the 1.8/2.2 is the theoretical number, wouldn't surprise me if its only 130 in the end. For reliability sake I recommend just running a 2.2 as it is.

2.2/1.8 heads are the same

they both suck

Yea I agree. After some advice from Meyagi I think 2.2 is the way to go. But I'll hold onto my 1.8 in case I ever have money to spare, then put the 2.2 heads on the 1.8 and drive a boosted time bomb

just gotta get through this winter so I'm thinking 2.2 to get me by. Wouldn't mind a 2.5 at some point. Ill see what this summer brings.
