I recently just purchase a 85 dx crx and my question is what will I have to do to swap a b16 ?, also will a zc bolt up to my transmission? thanks for the help.

 

Wow 85 w/ B16 thats going to be fast but i have no clue whats involved

 

Doesnt hasport have mount kits fer that year?? Check thier website...they should.....probably a bolt on conversion like the EF 88-91 kit.

 

Hasport has two generations of mounts for the 1st gen crx I believe. The first one didnt allow A/C, but I think the 2nd one does. There was one with the swap some chrome wheels (yeah yeah I know), I/H/E in an 85 or 86 in Arizona that had the first gen mounts in it for $1500. I thought the price was suspicously low, but apparently someone else on the board I was on flew in from Ohio and drove it back. Missed out on that one

 

Before you can do anything, you need to convert the car over to Si specs. The DX model has a carb and no fuel injection harness. Off the top, you'll need the Si's wiring harness, fuel pump, gas tank, and some other stuff.

It's a big job. From there, you can do just about anything if you have the $$$. A B16 will fit, but the mount kit and custom axles required are expensive (about 900 bucks for the two items).

I have an 87 CRX Si and was thinking about the B16A route, but instead opted for the 86-89 Integra engine. It's basically a USDM ZC engine. It's the only D series engine to hit US shores. You can find more info about the swap at:

Mounting the engine is the easy part. But the fuel and electrincal modifications are the hard part. Not that any of the stuff you need from a wrecked 1G SI it would be too expensive. But you are either going to have to do alot of work or pay someone else alot of money to do it for you. Regardless, I would not sell your car and get a 1G SI. The SI is alot heavier. So you would be giving up a significant performance advantage in doing so.

 

i wouldnt even bother with the dx personally thewiring is gonna be hell unless ur up for it there is no ecu in a dx so its not gonna be easy with an si there at least is a obd style similar to teh 88-91 efs wiring

 

The problem with the 1G SI is that it is really not a very light car. It is actually heavier than either a 1988 HF, 1988 DX, or 1989 HF. So if you want the lightest CRX swap possible AND you don't want to bother with carb to EFI conversion, go with one of these 2G cars. But if you want the ultimate in lightness, bite the bullet and go for a 1G non-SI.

 

Thanks for all the info. What about the zc will I have to go through the same process and can I use the same transmission?

 

The brown (note the emphasis on brown) top ZC will bolt into the 1G CRX. It requires a fuel injection system as well. The problem with brown top ZC's is that they are usually old and beat to hell. It's kind of a gamble.

The Sis were heavier, in part, because of the motor, swaybars, and rear seat slider rails.

You're adding a different (heavier) motor, you'll be adding swaybars and you can always source a lighter fixed rear seat from a DX.

In the end, the Si chassis wil only end up weighing a few lbs more, but it sure will be a lot easier to swap a motor into.
