I was in a low speed colision the other day with a roll back. Needless to say my 87 teg didnt fair too well. i just recently finished turboing the teg when the wreck happened. Its intercooled with an afc and 450cc injectors for fuel mangement. I have all the suspension goodies on it too Koni shocks, torstion bars, and Ground control coilovers. Anyways, does my motor swap over perty easily or do i have to modify a lot of stuff. The mounts are all the the same right? I know that i will have to use my axles and ecu. Only 86 and 87 Si were fuel injected? I know that the g1 crx is a real light car so it has posibities right there. If i found a carburated one cheap that would work if i could find some nice side draft webbers. How heavy is that g1 crx, my motor has 113 hp from the factory and a turbo helps with the power.

ok heres the dealio, the 86-87 integra is basicly the same chassi as the CRX but extended in the middle, so everything swaps over pretty much, im not sure about body parts, but i wouldnt want to put any teg body parts on my CRX anyways because the CRX is basicly plastic front end.

the koni's, the motor, basicly everything will swap over.

if you are selling anything let me know i might be interested, building a T3 turbo 1.5 FI REX this winter.

OldSchool,
Check the FAQs that are pinned at the top of the 1G CRX tech section. It has all the info you need on the swap. It is just about a bolt in.

BTW,
Welcome aboard!

As of right now the konis are NOT for sale (maybe later). Any help on the swap?

Seriously here's a section right straight out of the FAQs. Heck it's even got it's own section now. Nothing is left out.

Q: I want to make my car a hybrid and install a bigger, stronger engine. What engine is easy to install in a 1st Gen CRX?
A: The 1986-1989 Integra DOHC D16 engine and transmission will bolt right into a 1st Gen CRX. At the top of the family tree for the D Series, DOHC 1600cc, 16-valve engine is the JDM spec ZC engine of 135 hp. Next in line was the Euro-spec D16A8 which makes about 120 hp. In the US, we got the D16A1 Black Valve Cover version in the 1988-89 Integra, with 118 hp. And at the end of the line is the D16A1 Brown Valve Cover version in the 1986-87 Integra with 113hp.
Many people refer to all 1986-89 Integra engines as being a ZC, but this is not technically correct. ZC is Honda's term for the top rated version of any family of engines. Not many people realize that there was a ZC version of the SOHC D16 engine that was sold in Japan. If you can find all of the JDM parts, you could build a USDM D16 into a ZC. But those parts are rare and probably expensive.
The Brown and Black valve cover version of the DOHC D16 engine are very easy to install. The 88-89 Integra engine (black valve cover) is slightly more powerful than the 86-87 engines (brown valve cover) because it has a better flowing intake manifold, domed pistons with higher compression and lighter connecting rods. The black top D16 has a very different distributor and ECU that will not ?just plug-in? to a 1st Gen CRX. You CAN NOT use the brown top distributor on the black top engine.
The BROWN Valve cover is equipped with:
-Flat top pistons
-Thicker rods
-Square styled intake manifold
-Vacuum advance ignition with external coil
The BLACK Valve cover is equipped with:
-Domed pistons
-Slightly lighter rods
-Rounded intake manifold.
-Electronic advance distributor with internal coil.
ACTUAL SWAP INFO:
Engine Mounts (total of 3 mounts on 84-87 Civic/CRX's):
Use the stock Civic/CRX mounts on the rear cross member & front timing-belt side.
Use an 86-89 Integra tranny mount for the tranny. The Civic/CRX tranny mount will make the motor sit crooked if you use it, so don't.
Axles:
Use a complete set of 86-89 Integra axles including the intermediate shaft.
Knuckle/hub assembly:
In order to use an 86-89 Teg' engine + transmission, you have to use the 86-89 Integra knuckle/spindle assembly so that you can utilize the Integra 3-piece axles. The 86-89 Integra axles DO NOT plug into 84-87 Civic/CRX knuckle/spindle's.
Shift linkage:
Use a complete 86-89 Integra's shift linkage.
Wiring harness:
Use the 1st Gen CRX Si's wiring harness. Plugs right into the 86-87 Integra sensors, injectors, & distributor.
Distributor & ECU:
Make sure you use an 86-87 Integra ECU & Distributor. That's the only DOHC ECU (besides a JDM one) designed to work with a Vacuum Advance Ignition (distributor), which only came on the 86-87 Integra's.
***Do not use an 88-89 Teg' ECU or Distributor**** Simply because it has an internal coil ignition just like all the 88+ civic/CRX/Integra use, which is completely different than the 86-87 ignition components.

Only 86 and 87 Si were fuel injected?

Someone help me, I believe that all Si's are Fuel Inected. Si=Sport Injection. Just clearin' that up, lol.

[oldschoolteg]

im thinking 86 was the year when all the automakers started switching everything to FI. Did honda even make a FI motor in 85?

[C_piddy]

the 85 si is fuel injected

chris...

si = sport injection!!!!!!!

[Dan-O]

The Acura guys next door thought maybe it was Solenoid Injection.
I guessed sequential injection.
