Icon5 I know nothing about preludes, B20A5 help

Ok, I was refered from my typical site, to honda tech, to you guys....I hope you can gimmy an answer.

I have a 85 CRX, and am in the "slow" process of doing a swap. I started looking at motors, and found a 1990, B20A5 real cheap. Not blown, but in need of rebuild. So I start picking up the parts and I with help from another forums members realze the B20A5 uses different mounting points than a typical B series motor. Long story short, Hasport makes the mounts I am going to use and they are designed for a typical B series motor.... and I have been informed, the parts will not work together.

SO..... I have the entire top end from the B20A5 all ready. Picked and paid. So, "my question" Will the P-K2 head work on any other block?

Because it sounds like the B20A5 block will not fit in my CRX with out alot of work and custom mounts....and then no one knows because no one knows anyone who has done it. I am all about rebuilding a motor, and maybe welding up a few things.... but, this sounds like a WHOLE lot of work.... 'IF" it will work.

lol, if not, I got a disassembled PK2 head for sale.... :) everythings straight, comes with distro, cover, and all the nuts and bolts....

I think you're gonna have to put the b20a5 head for sale.
PK2 heads work only on b20aX series blocks and the b21a1 block.
They dont work on any other B series blocks because of the design of the head, the angle which way it sits and b/c it's a 2 liter with a short stroke...

For your CRX, you should've picked up a b20b or b20z if you were looking for displacement and torque for your CRX. They have motor mount kits for every B motor except ours

Yup and you are correct, it will be a whole lot of work for you to make your CRX work with a 3g Prelude motor


good luck, welcome to the board.

Although now that i think about it, there was a CRX with a b20a5 waaay back in the day.
That was before the h22 came out though.
