F22a1 vs F22b dohc

Cool. That's what I like to hear!

If you're actually doing a full build, then it doesn't matter all that much what motor you start with. The F22A, as I said before, will be easy on your pocket... and it's a very good design. The head may not look as impressive as DOHC, but it flows better than an H22 when modified.

You will want low compression for boost, But you wont want TOO low. If you are too low then out of boost the car will be slow as shit and basically you are only turbo fed power.

If you have a slightly higher compression you will still have a little pep out of boost to get you around and still be safe.

9.0 CR is still low, A f22a with carbon build up on the pistons would be close enough to 9 for all you know.

The chipped ECU alone won't cut it. You MUST get it tuned properly, or you will blow up your motor. A basemap is designed to get you to the tuner... not to rip around on the streets until you get around to tuning it. People make this mistake all too often. You must have your ECU tuned for YOUR setup. Even a tune from a similar setup won't be right.

thats what i told him. with a proper tune it can handle a good amount of boost on a stock bottom end. TUNING THE ECU IS CRUTIAL.

all i have to say is, (both motors stock) the f22b is a very nice upgrade from the f22a. once you throw the turbo into the mix, there's just too many variables.

yea...id rather go with the f22a for money reasons..and also an easier on labor.
