I am looking to build an all out drag car out of an 88-91 CRX? My friend has one that he's willing to sell me for $500. I thought about a B-series but that's too common so I've decided to go with an H22 or a K20. I know that their will be a lot of understeer with an H22, and I haven't heard of anything about the K20. I'm just wondering people's thoughts on whether I should put an H22 or a K20 into the CRX, and what would be required in completing the swap for both engines?

First off you want to build an "All out drag car" and are worried about understeer? both these swaps have been covered in alot of detail. The h22 requires a good amount of fabbing, but there is an excellent kit that uses and adaptor plate for the b series trans and h22. Hasport makes a mount kit to drop the k20 into a crx, its an expensive swap. Search and ypu will find a good amount of info on these swaps

thanks for the help. the only reason i threw in the whole understeer thing is because I posted this on another forum as well and people kept telling me about the understeer even though it wouldn't be that relevant. Thanks.

 

Do a K20A. Put some ITB's, Hondata, and some bigger cams. It will run crazy fast in a lightweight CRX

 

dont mean to jack this thread but where would I find this adaptor for the tranny?? Thanks

 

GO k20 VRROOOOM!!!

K20 is a great motor.. an h22a would be easier and would fit better. K series are quite tall..

 

how about an h23 if ur gonna waist that much money on a 160 hp k series just get an h23

 

k20a2s (rsx s) make 220 hp dumbass

Yeah you're thinking of the shitty k20a3 (ep3 motor). K20A2 also has higher redline than h22/h23, but it is more expensive.

Then you'll need a cowl hood, or maybe cut out the stock hood, because the ITBs won't clear.

I would go for the k20. Even though the h22 is a mad torque machine, parts are expensive, and not many manufacturers spend their time developing parts for that motor.

And what's so wrong with b18 head and b20 block?

........

b makes power just fine. and it fits in a crx for less then 5 grand. could use that money you save on ENGINE INTERNALS to "make the power". how many EF k20 swaps have you completed? axles mounts wiring and the welding make it PROHIBITAVLEY expensive to the avereage honda person right now...

please tell me you joking. if not, <u>dont post again until you've read on here for at least another 6 months.</u>

spreading bad information sucks goat dick.

to the original thread starter:

if you run a k20a2, youll be my hero, thats what id really like. you can search this section of the forums for my k20 crx swap thread. its a tight fit, good amount of fab work.

2point2 [who posted above] runs an h22 turbo in his crx last time i checked, so if that floats your boat, search for his thread here on honda-tech, theres great info in there to show you all the fabrication, and theres a good amount of it, to get it into the car. neither of the two swaps you list are bolt in, not by a long shot.

but im not gonna assume your just wishing for something youll never do. right?

 

well if u wanted a fast CRX right off the bat an '88 CRX Hf is one of the lightest

 

I would go CRvetc if I were you. IMO the H22 is much too heavy for a crx, seems like you loose the point of power to weight ratio. And the k series is too new, agiain imo, to swap now. Not enough part options, and it's expensive. Give it a year or two and it would probably be eaiser...

 

im pretty sure its been proven that the h22 is not THAT much more heavier than a b-series motor.....

 

its like a 35 pound diffrence

 

u guys need to calm down he said k20 I thought he was talking about the k20 in new civic hb he said nothing about the rsx k20

you need to think before you speak. The amount of work that goes into a k20 swap is insane and he'd spend probably 4x the amount a k20a3 costs just to put it in. People aren't THAT stupid.

Plus, why would you think k20a3 when you're talking h22? k20 with 200-220hp. h22 with 195h-200hp. Amazing.

 

christ! not al h22's are 195 either

y can't we all just get along

 

The H series motor is NOT as heavy as everyone claims it to be. It just takes more fabrication, but it does have way more torque.

B16B - 170hp, 117lb torque
B18C1 - 180hp 121 lbs of torque
B18C5 - 195hp, 130lbs of torque


Now...

H22A 200hp 160lbs torque

and
K20A - 220hp, 158torque


Not that much of a difference?
B series is the top of our sport for a reason.

H22 is the best way to go on a budget for a Drag car. I autocross my H22 civic all the time. So i can personally tell you that a H22 is not as much heavier than a B series as most people think. Because i had a B series in my car before i did the H22 Swap. A matter a fact. When i first weighted in my B16 turbo, my car was 2310 pounds. Now that i am all motor H22, my car weights about 2270.

 

For all drag, go h22, you can build, and turbo it at a good price. The k20 is a FANTASTIC choice (thats what im doing), but it dosent respond well to FI, and is expensive as hell!!

It seems that everyone agrees that a K20 into a CRX would be the best choice. I've got $3000 and a friend whose willing to sell me his stock CRX for $500, so Ima see where I'm at by the end of the summer and decide what to do from there. So, to doublethink, don't worry, I am actually looking to do this, just a matter of getting the money together.
