Default B21A1 Engine Swap

I was wondering if anyone out there ever took a motor out of a 90 Prelude. becouse i want to know if there is a engine mount kit available for the 97 Del Sol and also what kind of axels are suggested for this swap. and does anyone know if a GSR trans would bolt up or not.


thanks 4life

they made that motor for less than 3 years for a reason.

WORST rod/stroke ever........... plus I'm quite sure that is does not share anything with the new B-series.

Nope, that motor sucks.

Plus, you can't (legally) put an older engine in a newer chassis.......good luck getting inspection if you do.

Go with a B or H series swap. If $$ is an issue, go SOHC VTEC for now, they can be picked up for a song. What model is your del Sol? You have a 2 in 3 chance it already has a VTEC engine!!

like the doctor just said...

that is the absolute worst engine honda ever made.

no b.s.
I had to swap a head on one of those one time and i would rather chew glass and rusty nails before ever even being in the same garage as that motor again.

I dont know if it's a bad motor, I still see quite a few 88-91 ludes running around.

I assumed it was because of the really long stroke of the motor. But I looked it up:
Bore= ~94 mm, Stroke= ~79mm
