Yep, the 1.8 is physically larger so the head, manifolds, etc. (anything that is part of the longblock really) won't work together.

If it were a Honda (got the idea from you, hustler) they would be incompatible on a B-H series level.

Figured but i know i remember reading something about a head swap....must've just been the "high flowing" '99 head to another 1.8?

Thanks,
Brian

1.8's will swap the 94 -> 97 bottom end with all heads, the same with the others... The biggest issue is with the 01+ heads with the VVT... you need something to control it.

The 99/00 with VCIS... will swap to an M1 1.8 without issue... you just need to swap the CAS in, and make sure you have something to control the VCIS... a solinoid or something like that... <G>

Well documented on m.net and solomiata... <G>

Sometimes I wish I found a 99 head for mine when I put the used 1.8 bottom in... instead of a low-mileage 97. The advantage was price and availability... since I got the head from a buddy who was doing a motor swap at the same time. <G>

Dave,
