I'm guessing your swap is in a 90 hatch? And you only did a 15.1? Honestly that sucks. Either something's wrong with your car or you simply can't drive.

My friend had an SiR in a 90 hatch and did a 14.5 with I/E. An SiR in a 2100lb CRX should do atleast mid 14's stock, and with I/H/E should be yielding very low 14's/high 13's. With a better clutch, lightened flywheel, and a 55 shot, plus some good tires up front...hello 12's.

I'm just basing my estimated 1/4 times off of experience (my car with a 55 shot and bolt ons did a 14.45 and that was on a bad day where my best N/A run was only a 15.8 instead of the usual 15.4), other people's 1/4 mile times, and common knowledge.

There's just no reason a 1900 lb car (after being stripped, probably less weight even) with around 180 flywheel shouldn't be running 13's.

Here's a 1/4 mile calculator which can usually give a rough estimate of what to expect based on weigh and horsepower: http://robrobinette.com/et.htm
I know it doesn't take alot of things into consideration but nonetheless it gives a rough estimate.

My point of this thread was really just to learn what I would need other than the motor itself, to get the CRX running. I guess it was partly my fault that this got misinterpreted as what I needed to get it running 13's, which is not quite the same, and as I am not as interested in what it will run because I sort of already know.

An example would be: axles, ecu, mounts, etc etc

Thanks!
