Hi, been looking around and I can't seem to find any engines for sale with a h22a8 engine for sale, are they really rare? Or is the h22a engine the same thing? I no the h22a5 and h22a7 are different from mine. But some blocks just have the h22a printed on them and no other details ? : / appreciated the help, thanks in advance

H22a8 engines were put in 5th gens 97" onwards. H22a5's before 97" most info on h22a in above link obv different gearboxes were bolted to each but would presume they are interchangeable.

Gearboxes are interchangeable, except type-s (the atts makes it all different).

H22a8's are the least common type.
They were also fitted to type-s 5th gens, but if you find an h22a8 from a type-s, you don't want it - it won't fit because the block is different to take the atts unit on the type-s gearbox.

Other than that, differences between the different h22s are essentially different cams and compression ratios.

An h22a5 would drop straight in a non type-s h22a8 lude, but you might need the ecu from the donor car as well. Presumably the looms would be the same... Anyone? 5th gen experts? Is that right?

Edit:

might need to swap your distributor off the a8 onto the a5 as well.

H22a is found in Jdm ludes, the type s has the red top H22a with the extra bhp.

H22a8 is found in all UK manual ludes from 99 onwards.

H22a5 is found in all UK manual ludes from 97 - 99, and all UK automatic ludes.

FWIW/clarity the H22a8 above also has a red top.

I'm not sure, but this may be the first time I have ever been "On topic" in a vaguely technical thread

Good luck with it.
