1990crxproject

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

1990crxproject

so your aying a b16 huh? thats where im not sure what to do, where to get the parts from and such....any info would help......im still not sure, stay d series or go into b series and i dont wanna do a k so

wolfsbain

well congrats on the crx, im doing the same thing, but im planning on a b18 and boost, wish you luck on the build and tons of fun with it when you get it running.

soon2befast

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.

soon2befast

i mean b16a not a1 sorry

1990crxproject

yeah so im thinking its down to a b18 or b16.....im reading up on the parts and just seems the b18 wold be alot easier and better with the bigger displacement so, im gonna keep reading and hope to hear from you guys

1990crxproject

oh and i forgot to as for everyone who might have an idea......i know the b16 is vtec but is vtec worth it? and i heard it was ment to rev high.....just throwing some questions out there........anyone know where there i can read up on a good comparison

soon2befast

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

soon2befast

an ls can handle 8ibs allday i would just stud it and do a different head gasket. and its not that hard to street tune it u can probly find somone clouse to were u live that has done it time and time agine if u dont wont to do it your self trust me i done this with my old ef hatch and its still running around town on 8ibs

but if he has the money why not get a gsr motor and trans?

EF-Monster

LsVtec bored 2.0 type r tranny with ls 5th gear!

TheEf2Kid

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.

TheEf2Kid

bro you talk about a ls turbo. same thing no traction. honestly i've seen H2b cars beat turbo cars. my other friends car smoked a cbr600 on the freeway, the cbr hit governor at 163mph. and my friend flow right by him.

Sandman77

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?

TheEf2Kid

hybrid tranny, 1st & 2nd b16, 3,4,5 ls. im here in the central valley as well. and i run into freeway races a lot.

Sandman77

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.

TheEf2Kid

bro my friend has a h2b in his rex fully built with turbo and he pushing 400-500whp! i dont remember exact but its in between.

Sandman77

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.

1990crxproject

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

str8shooter

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.

TheEf2Kid

^^^^ THANK YOU!

Sandman77

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.
