Going h23 and have a couple q's
 

I own a 5th gen coupe.

I've decided on an h23 because of the torque and cost. I know I need a Bigger radiator, like the Dual Core del Sol radiator, and Special Mounts. But which Axels should I use?

Also, is there a big gap between the Catalytic Converter and the Header downpipe? How is that setup once the motor is in my car?

Also, I know I will have to remove A/C, but will there be enough room for say a T3/T4? How is the space on the motor.

And Finally, How bad ass is this motor in a civic? Haha thanks.

I used a Fluidiine civic radiator with my H22 and it worked fine.

The axles you'll need to use are dependent on the mounts you will use. Just ask when you get your mounts what they recomend to run.

If I remeber right and the H23 and H22 are similar, the header down pipe is actually longer, so your exhaust will need to be cut to fit.

About the turbo, I would assume it would fit, but don't know for sure.

you will ahve to cut to fit no matter what...the h23/h22 headers are much longer than civic ones. you can put in a/c with teh a/c bracket that comes with the Hasport and HCP kits now, and then for power steering you have to customize some.
in my 94 hatch i pulled the a/c and have lots of room for probably a t66 or more...
