What he was trying to say here is...
86-89 motors use the same injectors, distributor, alternator etc..
hence you wont have a wiring job to do, only mounts

if you want an easy swap into a crx, buy a zc motor it and boost it

go to homemadeturbo.com there are tons of single cam home made turbos there to look at...

oh i definetly am going to DOHC. i just dont know which swap to do and if i can get a good block from the junkyard and build it up, i would do that. could i get the b18a bottom end, and find maybe a b18c head? or soemthing along those lines...more power is always better...

B18a bottom and a VTEC head would be a very nice motor in a CRX. If you need any pointers, feel free to ask. KJ has an LS/VTEC setup in his CRX, and from my understanding it's a pretty potent motor. With OEM internals!

ls/vtec is a great way to go... but you might be better off in the long run with a gsr motor w/ some minor mods like a intake manifold & some cams.

reason i say this is...
lsvtec can get expensive compared to a complete swap
lsvtec wont last as long 50% of the time because of it's high compression

to each is own.. i say go lsvtec in a crx... fun fun

I don't think LS/VTEC has high compression unless you make it have high compression.

GSR internals on an LS block with a GSR head should be fine. KJ? Thoughts?

heh....
why would you build an ls/vtec setup w/ stock ls pistons ?
you would be shooting you're self in the foot.
you would want atleast jdm b16 or ctr pistons with an ls crank & rods in a 1.8 block.

Never said use LS pistons. I said GSR internals.

I found this online somewhere, looks like it's mostly accurate. However, credibilty is not established.

B16a head and pr3 pistons 11.2

B16a head and p30 pistons 11.4

B16a head and p72 (ao) pistons 9.9

B16a head and p72 (00) pistons 10.5

B16a head and p73 (ao) pistons 10.7

B16a head and p73 (00) pistons 11.2

B16a head and p61 pistons 10.4

B16a head and pct (CTR) pistons 12.2-3ish

B16a head and pr4 pistons 9.5

Add .2 to all to calculate the GSR head with all of these.

Type r and b17a heads have the same combustion chamber so calculates the same.
