about to aquire a 91 honda crx.
Friday, October 22, 2010 10:04 AM


so, a while back i bought a 86 rx7 for $300. it's been sitting in my back yard as i don't have time or space to pull, rebuild, and reinstall the engine. so, someone made me an offer as an even trade on the above crx, it runs, drives, and comes with a spare engine that the manual trans was swapped from. i know absolutely NOTHING about hondas except vtak just kicked in yo. started the car, it ran somewhat rough, but wasn't making any ticking/abnormal noise. i figure if all else fails and i don't like the car, i can sell it easier than i could the FC.

My motor in my eg is out of an Sir crx. My buddy has a complete JDM conversion in his basement for that car. GSR motor plus LS tranny plus LSD one fun daily driver.

So what's my best bet to get a reliable, naturally aspirated 175 hp out of this car?

Bingo/\ or cheap b20+b16 head +rods and pistons + ls tranny OBD1 conversion. 3500 for 210+ horsepower around 150 torque and cheaper than a ITR swap.
Look i no me hondas. ROFL.

i'll be getting it here tomorrow. trading one lump for another

but anyway, the .org has spoiled me, the layout of this site is so friendly, i doubt i'd find a honda based site that's as good as the .org

What you give up in layout is completely outweighed by an over-abundant knowledge base. If you aren't familiar with Honda-tech.com, you will quickly learn why many of us spend time over there. You'll learn far more from Honda-tech than you ever could from this place.

What rod's and pistons are you talking about using? Also, you realize that its not a case of just putting a b16 head on a b20 and calling it a day right?

Personally, I'd go with a GSR swap. With all these people looking for LS/Vtec or K series and now even J series its made a GSR a lot cheaper. A GSR with a few bolt-ons will move that little car pretty good. The entire swap can be had for a good price. You don't want the garbage LS tranny anyways. You can either mod your harness or use one from a vtec OBD 1 car. Personally I'd find yourself an OBD1 civic harness. They use a one piece harness and its real easy to install.

I say good luck. when I totalled my Z24 back in 'o3, all I could afford was a CR-X a friend of a friend was selling. I bought it at night, so I didnt noticed the dinged-up fenders.. but thought nothing of it. then a couple days later, the motor melted down. the temp gauge wasnt working properly and I overheated. replaced the motor, and during that time, noticed the frame was bent.. whole front end was tweaked hard

picked up a strait CR-X and swapped the goods over. it 'ran rough' but figured it'd be ok.. even tho the wiring harness inside caught fire for no reason. after that, every time I hit the right turn signal, the door ajar buzzer would go off o.0 then a couple days later, it stopped starting up. sold it and no one after that could figure out what was wrong.. havent seen the car since

sold it for a Volkswagen Golf

as far as making it faster, I agree with Rabbit. GS-R swap and call it done. thats what I was gonna do with mine

Ls trannys are junk but mainly becuase they are geared higher than all the rest. which in a little crx he'll get great gas mileage and it won't affect him plus they are dirt cheap.
B20 vtec converion kits are easy to get and the rods are the weak link from what i have seen. mind you the sleeves are thin from the factory. their are many right ups on line from reliable sources on how to build one of these motors.
A gsr motor would move that little car pretty well but finding a gsr motor that hasn't been beat on is an issue these days.
Also 8200 rpms In my little b16a is pretty nuts mind you stock they run outa breath at 7500. i have a new chip for mine with a rpm cap of 7600 fuel cut 7800 and vtec 4500. now thats fun. the higher you rev the more wear on your piston rings. mind you rabbit knows more than me on hondas.

You never answered my original question. You made it seem as if you wanted to use b16 rods and pistons, which obviously that isn't correct. So what rods and pistons are you talking about using? If you were talking any type of vtec pistons on any other rods I hope you know that requires shot peening the rods. Also, its not as easy as you make it sound of "just slap a b16 head on." There is more work to it then that. The wiring isn't bad, but still needs re-wired for knock sensor, vtec and a couple others. Besides the fact of converting to OBD1. There are other things because you're forgetting Vtec is controlled by oil pressure. You need a way to supply it oil. There is a few things on the head and head gasket that need modified. This is the reason I say do a GSR swap and be done.

You say being geared higher wont effect him. How do you figure it wont effect him? Gearing drastically changes your acceleration. Sounds like a pretty big effect to me.

Rabbit, say I didn't want to swap any time soon. I believe the engine in the car now is a d15b2, I got a spare with it which I believe to be a d16a6. Is there anything worthwhile I could do with either engine?

There are a few things D series have proved. They can make good power with work. It will never be as easy to make power as a B series. Right now, most importantly they are cheap. You can boost that engine. Most will tell you "well you can boost that engine and put out as much as a B series." Ok, so? You can build a junk yard turbo setup for this car for 500 dollars or less depending on the deals you get. With no vtec you could probably tune this yourself with just a wideband and a SAFC. With a spare engine.....@!#$ i'd boost the hell out of that thing. See how much boost you can run before you blow it, lol. Have fun with it. Parts are cheap and easy to come by.

You could also do a mini-me swap. Which is basically a vtec head on your block. Thinks LS/Vtec for the D-Series. Like I said, parts are cheap and easy. I still say boost it.

Sorry, I forgot to add. You could pretty much leave the engine stock. Do suspension mods first. Then have a blast racing auto x with the car. When you do the engine swap the suspension would still be good.

What it really comes down to is how fast do you want to go? If you're just looking for a fun little car, but not a real beast that will beat everything on the road. Just swap an LS in there. They're still good motors and you can always build off that. I have seen PLENTY of LS motors that have been boosted making 300+ whp. Which in a CRX is more then enough. Hell i've driven stock LS motors with just I/E in a CRX and it was a blast. They're such small cars it doesn't take much. Think miata.....

It is a really light car... I was able to pust it into my yard one handed. Don't know if you can tell from the pictures, but it's a manual steering car and the a/c has been removed, so the only belt driven accessory is the alternator. I think really, 130hp in this car would be more than sufficient, but I. Sure I'll want more later.

Then save the money and go LS. Later on when you want more power boost it. With the K series crave B-Series parts are getting retardedly cheap.

yea, retardedly.....I just made that up.

Yeah Iknow it's work but still reativly cheap. and on rods i ment an actual forged rod piston combo designed for that combination. I am still learning.
