I hear its a hard car to swap. What makes it so hard? Do mounts line up and stuff?

 

If you get a 86-87 Si then there are a couple of swaps that are not to hard. If you get a carb motor then its ALOT of work to get it swapped over to MPFI

 

the 1g crx is a carberated engine car 2g is fuel injected

all first gens are?

 

the first gen SI's are FI.

 

I think I may just stay away from the first gen then.

Why is that? Because all the 1g Si models were fuel injected...don't listen to the 16 year old. He wasn't even born while they were still in production.

The real problem with the 1g, and this isn't even specific to Hondas, is the condition of your find. A lot of 1g are nearing the end of their useful life and it shows...especially in the North with the salted roads and the rust that follows. Some replacement parts are getting hard(er) to find than they used to be.

Compare a 1988 Si and a 1985 Si, both in brand new condition, and you'd find it harder to pick a winner than you think.

 

there was no 85 civic si.. only 86.. am i right ?

 

don't do it! get the 2nd gen one lol much better crx

If you want to split hairs, there was no Civic Si until 1986...but the CRX Si came out in 1985.

To answer the original question...For a relatively easy bolt in swap:
D16a1 - 113hp(86-87) or 118hp(88-89)...the 88-89 will be slightly more wiring
JDM Browntop DOHC ZC at 135PS(133hp)....it made 5 more hp than the much more popular, later blacktop ZC (for you obscure Honda trivia buffs).

There is a Hasport B-series mount kit for the 1st gen...it works best with the B16 but people have made the B18s fit with some minor compromises. Its a tight fit though.

And from what I've read, the stock 1st gen engines were a little more robust and boost friendly than the 88+. Mugen even sold a whole turbo kit back in the day.

Considering the weight of a 85 Si(1890 lb), a fairly inexpensive dohc ZC at 133hp makes for a screaming little performer with slightly better power to weight ratio then the best/fastest B16 second gen.

To be fair, theres more aftermarket support for the second gen and the looks are a little sleeker. But why, inevitably, does some tool always show up and say something like "second gens rule!" when they each have their own merits and are both gifted with the CRX name? Save it for the Del Sols.

 

^^ damn it I think you always beat me to the truth on 1gen.

85 CRX Si actually has slightly different connectors just a little did you know.

Also the 1g CRX/3g Civic are completely different compared to 2g CRX/4g Civic. The 1g use torsion bars and solid axle beam in the back.

The 84 CRX HF is the lightest CRX out there , convert it to fuel injection drop in a b-series and you are golden.

There is actually a b20vtec turbo'd with a/c. For real these guys were crazy. I don't know where my link is to it. but its a red 1g CRX.

Also if you are converting to 88-89 d16a1 converts the ignition system from Vacuum advance dizzy to electronical.

Thats pretty much the biggy on it.

All SI models 85 and up are Fuel Injected. all other Crx/civc from 84-87 are carberated.

nevermind guys... the guy had no idea what trim it was, but it's carbed so I hung up.
