Default B20B w/ JDM ITR transmission????

I have just finished my swap. It's a JDM B20B mated to a JDM ITR tranny w/ a clutchmasters stage 4. My next step is the B20/VTEC. As for right now the power is great but I haven't taken it down the highway(if you know what I mean). How will this setup run on the highway?? What kind of digits would I see on the speedo?

The reasonI'm asking is because me and my friends are in a very heated debate on how beneficial the ITR tranny will be on the highway versus the long geared LS tranny. One friend said b/c of my tranny I would be around the same as a JDM B16A in the big #s because I have the close ratio tranny and the large torque band. While another one says that b/c the B20 has no kind of hp that it'll die out early no matter what kind of tranny is in there.

To tell you all the truth I have no clue. 1st the JDM B16 revs out at like 8300rpm while I'm only at 7000rpm. I think that'll make a difference. Then again the tranny is close geared to keep the power up(torque). For some reason I think that if I were to run a JDM B16A with the same mods I have on the highway I would jump out on them but they would eventually catch up and run past me. Just my .02. I really have no clue. Oh and I'm not gonna actually try and find someone to test that theory out with. Just a comparison b/c I've ridden in plenty JDM B16A hatches.

This is the 1st B20 setup in my import circle of friends(had to be different). Just trying to get some insight b4 I take down the highway and see what I'm working with.

Oh and my setup is
1992 Civic CX hatch
JDM B20B
JDM ITR Tranny
AEM short ram(No inner fenders so no CAI)
JDM DC 4-1 header w/ 2.5 collector
2.5 inlet/outlet Carsound Cat
Apexi N1 full catback
Clutchmasters Stage 4
AEM adjustable cam gears

i think ur car is going to act like it has gsr w/o vtec its going to eat more gas then the ls tranny and when ur in the freeway ur gonna be at hi rpm doing the speed limit and ur not gonna have top end and the about b16a tranny and itr are the same up to 4 and final gear.

ups for lsd

I really don't see how it would act like a GSR w/o vtec. The reason I say this is because first off the displacement is totally different(1.8 vs 2.0). Secondly the hp and torque ratings are very very very different(170hp & 121 torque vs. 126hp & 133 torque). I think a GSR w/o the VTEC engagement wouldn't run anything close to a B20. Two rediculously different setups.

How about "will the B20 setup feel strong at high rpms?" then the answer is easy---&gt; NO.

I would love a B20 with an ITR tranny. very smooth power delivery throughout the rev-range and the ITR tranny short gearing makes it very usable throughout all ranges of speed/mph.

I think you will like it, but no doubt a CRVTEC will be even better.
