conversion fa20 head with fb25T block

[ft86-UAE]

hello,

do some here now if we can make a hybrid between the to enignes. bigger block with fa heads?

that they share the same staff.

Thanks,

Why would you want to?

If I'm thinking about this correctly you would end up either lowering the compression on the NA motor (2.5 block without turbo with the 2.0 head) ot increasing the compression on the turbo motor (if you left the turbo on the fb25). Both would lower the end results of the build, if you want a turbo, swap in the fb, or build the bottom end of the fa (lowering compression), or if you want NA check to see if you can swap the crank from the fb into the fa to increase displacement.

yeah but the pistons will have be different with a longer stroke, the cups wont maximize turbulence to mix the air and fuel properly, plus we dont know how the new heads handle forced induction just yet or if the bigger lower block with the fa20 heads will even clear the frame, plus the the FA20 has 2 ecus, find a tuning solution first before i would attempt a Frankenstein build

plus there is not FB25T
