Default LS swap in CRX

alright i own a 1990 CRX Si, im doing a ls swap into it and this is all the stuff i have for my swap LMK if theres anything i need i might be missing.

-OBD0 LS Longblock
-Cable B16 Tranny
-Cut and welded B series shift linkage
-90-93 teggy axles
-mounts (HCP)
-ECU
-OBD0 Alternator
-OBD0 Dizzy
-OBD0 b series injectors
-starter
-clutch/flywheel /prss plate
-90-93 thrttle cable
-90-93 integra rear bracket

also, even if im using aftermarket mounts for the swap do i need too hammer in room for the alternator?

PLZ give me all the help you can give i wanna make sure i got everything!

Yes you will still need to hammer the frame some to fit the alternator

You also need axels. I can't remember if you need 90-91 or 92-93 axels or if there is even a difference.

-rear bracket from a 90-93 integra
-axles from a 90-93 integra along with the halfshaft
-throttle caable from an 90-93 integra or 88-91 si throttle cable
-clutch cable from a 90-93 integra, although i used my stock dx one and it worked fine
-as far as banging the frame for the alternator, i did this and after hooking it up i see i didnt need to do this. use a shorter belt if it rubs

what about your hubs? I'm pretty sure the 90-93 integra axles do not fit into the stock crx hubs. you'll either need to re-use your crx outer joints or swap the whole front brake assemblies with a set from a 90+ teg or 92+ civic.

plus you'll probably have to cut the front mount off the crossmember.

doesn't the HCP mounts come with the rear bracket?

Read alot about this "shorter than stock alternator belt" is it just the stock ls belt, or is it shorter than that one? so you can avoid the banging just in the belt?

Everything sounds good but if you want to do the swap right integra axles will get you by but i have found they are a little to long for this application it rides rough compared to the stock length when i did my swap i had a company in Florida called http://www.raxles.com make the proper axles to fit identically as you would factory.

That means you have shitty mounts. Mine fit perfect and have all the free play they will ever need in any driving condition (over 20XXXkms since I went B series).

DA Throttle cable and bracket, makes it a bolt on application, if not a custom mount will be needed.
DA clutch cable, the stock one will work but you will NOT be able to adjust your clutch.

It depends on your cltuch/release brearing/ mounts. I would just find one at a wrecking yard and use it. I did it, and I get 100% adjustment that you would get in a B series cable car, like a DA integra .

do you have a mid shaft? youll need one of those with the axles. also youll need headers to bolt to your exhaust, the ls bolt holes dont line up, at best, or youll have a 2'' gap between the headers and the cat
