Default my 1990 crx project

so im coming to you guys for information. im currently overseas in iraq. in march i went on leave and found a 1990 crx and bought it with intentions of some type of swap. about a month ago i also bought a 2003 evo so now my crx will be a street driven toy. i really dont have a budget, but im not dropping alot of money into it. i want it to be fun and want to be able to rip around. i will wanna boost it but finding the right motor/tranny combo is where im stuck at now. i hope to hear from you guys......maybe a goal of 220-250hp and time isnt really important. im coming home in a couple weeks so im trying to piece together the parts list. i try to get on the internet at least once everyday or two so i look foward to hearing from you guys

Put a k20 in it if you have the money. Or the easiest would be a JDM B16a. If you get the B16, make sure to bash in your engine bay a little on the drivers side because the alternator will hit it and bend the pulley a little. Plus the swap will bolt in directly. I have a 88 Crx with the 1st Gen B16a and love it, any questions or help, let me know

i would do a b18a1. thats what im doing and they r very good for boost and easy to tune compared to a vtec motor. and u can get all the swap and all the boost stuff for as much as a b16a1.

the b16 can handle higher revs because of the shorter strock but is vtec worth it that all depends on who u talk to i think i would rather have boost and the b18a1 is grate for that. the onlything wrong with vtec boost is the fuel jump when u hit vtec makes it a little harder to tune by your self.

But if he is doing turbo you dont want to tune it by yourself anyways you run way to much of a chance of blowing your motor you would need to get it professionaly tuned no matter what motor you boost

honestly if you want a reliable and fun to drive for your rex. go H2b with a gsr tranny. less money then k20 and more impressive. torquey son of bitch and you will kill any k20 that will pull up next to you.


heres my buddies crx with h2b:

ya if you grab traction. my buddy didnt have any traction through first gear with his h22 in his prelude. and he only had bolt ons...i say ls turbo will be koo. just build the block and 250whp will be cake.

well idk where your from but freeway races arnt big here in the central valley. its all from a dig. so if you know how to drive, the boost lag can be used to your advantage. ive seen it many times. h2b the gears are too short for the torque. thats assuming youd use a b16 tranny rite?

na i wouldnt use ls 3,4,and 5. 3 and 4 will be too long. but this guy is trying to boost anyway. why throwout a h2b setup??? best engines foor boost when it comes to honda is the ls or b20 cuz the low compression. if hes after 220-250 whp build the block to handle high boost and get aftermarket studs. its perfect without a hybrid tranny. stock gsr or even ls.

thats kool man. but what was asked for is 220-250 whp. hes obviously not looking for a beast. just something he can have fun in. so your buddys 400 something horsepower h2b is irrelavent here. im sure if he wanted a "rape all" monster hed build the evo.

alright, so ive read what everyone has been posting, and i agree.....this car will be a toy, to romp on for all the little honda clowns in my town....im trying to keep the evo stock, because its an evo, really dont need much.....from what ive been looking up......b18a1 or b1 either or with a built bottom end and boost should get me the numbers.....so i plan on getting it in the car first then set it up for boost after, anyone know of a good turbo set-up for reliable 250 plus horse......i was thinking keeping ls tranny as well until i hear another good choice, i heard the h2b swap is a good drag set up, just trying to keep things easy for the parts list

For only 250 whp, I would suggest the H2B or H2D. My buddy has an H2D setup in his ef sedan making 192whp on motor, and just under 250whp on a 50 shot.

that would be nice but i didnt hear anything about spray. the best boost setup for that power would be a ls or b20 turbo. h2b and h2d are both great setups ive just experienced h series sitting out for a week or so till a part was found. b series parts are everywhere. easier when something goes out wich we all know happens.best bet is a b series turbo setup. greddy has full turbo kits you might wanna look into. i think carb legal as well if that matters.
