whats the difference between the civic R motor and Integra R motor? i know the displacement is difference , but what about the internals and tranny? which motor would you prefer inside a EG?

 

Crank rods and pistons make 1.6L 10.8:1 CR.
CTR and ITR blocks themselves are the same. As are the cylinder heads.
Intake cam is different also.
Trans is same as USDM ITR and 96spec R transmission.

1.8L B18C is always better.

 

What about a ITR motor with CTR Pistons & CTR Intake Cam. How much better would that be from stock ITR motor?

 

The CTR carries the longer gear ratios of the SiR not the ITR's info via Hyper Rev.

 

No, CTR has same as 96 spec/USDM R transmission. Obviously the ECU is a bit different to deal with all the changes that Stephen mentioned.

 

Actually no they didn't in 97-98 CTR used the 97-98 SiR trans with 2-3-4 gear ratio shorten. This is the Main reason the CTR 98' loses to ITR 98' in 1/4 mile run. Which can be seen in the Best MotoRing vol1 R legend edition and also mentions the SiR trans when the test concludes.

I think Racer X settled that one.
