d16a1 on 87 rex?

[89rex]

hey whats up ?well i just got an 87 rex si the d15a3 has a blown head gasket . i been trying to search for this but i cant get the rite anwer. i read that a d16a1 motor from a 89 teg. fits my 87 rex. is this truth ? and if it is will my si tranny bolt to the d16a1 motor? and if not how hard is it to fit it. thanx for any help.

The d16a1 from the 86-97 teg will drop right in. 88-89 teg's have different mounts on the block

[89rex]

do i have to switch the tranny and front suspention too?? or i can use my tranny ?

[SOHCinWA]

the D tranny will work just fine. Why would you have to change suspension???

[89rex]

well i heart that when using the motor i have to change from the tranny axels shift link and all the front suspention from the integra . is it worth swaping the d15a3 for the d16a1 ? or is it anything that i can do with the d15 engine?

[SOHCinWA]

IMO I would keep the D motor... But thats just my $.02

the 86-89 Integra D16A1 will bolt right into your 87 Si - you will need to use the Integra transmission, intermediate axle shaft, front knuckles/hubs and shift linkage - all of that bolts right in since the early Integra and the 1st gen CRX used the same chassis platform - the least amount of work would be to use the 86-87 D16A1 since it uses the vacuum advance ignition like your Si - you would need the 86-87 Integra ECU - the 88-89 D16A1 used electronic ignition advance and using it will result in you needing to add wiring for it and using the 88-89 Integra ECU - although it is a little more work, using the 88-89 engine is the better option since it has about 5 more horsepower and a better intake manifold and throttle body set-up - it is also a better engine all things considered - the D15A3 that came in your car is not like any other D-series engine

[89rex]

is it any other option available apart from changing everything from the integra chassis?

No, not really. A freind of mine did all this to drop a built B. If he would put a week or so of work into it, the car would be a freaking monster.

Anyway, the DOHC D in the CRX is really worth the trouble. It is a lot more fun and will really chage teh character of the car in a good way.

Heres a writeup I found on rpr.com. A little searching goes along way, especially when countless others have already traveled the path.
