b17 swap to my 91 rs. comolete noob here sorry

Hey guys just joined up I have enjoyed reading posts here. Yesterday I bought a b17 with everything… Ys1 tranny LSD axles, ecu etc. Was a pretty good deal and I thought it would be a good swap for my car. Anyway I have questions about engine mounts wiring and what to look out for. I will be accumulating parts for the next month so any advice on what to buy would be greatly appreciated.

Bump

Search our Teg Tips and google. Swap is similar to all obd1/2 into obd0 chassis.

LSD? What’s the story behind that? The YS1 didn’t come from the factory with an LSD here in the US or Canada. It was available as an option in Japan though. You should double check to see that the seller wasn’t lying.

And take Tegfan’s advice and check out the engine swap guide, it’s old but it’s all still relevant and good reading. I’d suggest converting to OBD1. There are also multiple write ups on how to do that both here and elsewhere online.

Thank you guys I will do some more research. As far as the lsd goes I have no idea where I got that idea. The seller didn’t tell me that. I wish it was lol. Anyway thanks I’ll post an update when I get it started.

I ran my 00 jdm itr swap obd0. I used the obd0 harness for the engine, used a obd0 b16a vtec distributor and obd0 vtec ecu. I did run the obd2 injectors, other plugs like distributor and fire wall plug was all obd0. Took my pwo ecu to get chipped fir my set up and done. I did have to run the vtec line and add vtec pressure switch, hook up the knock sensor.
I guess it would be much easier to get jumper to obd1.

dang ya that makes sense, however very much over my head. If I had someone helping me who had done this I would. But Im going to try the jumper anyway. Sounds like your build was pretty mean do you still have it?

With the current jumpers that are available I’d say converting to OBD1 isn’t any more difficult than staying OBD0. They just require different parts, so mostly it depends on what parts you have on hand or want to buy to complete the swap. Personally I don’t see any reason to stay OBD0. It could be easier, it could be cheaper, but it also could be more problematic in terms of how well the car runs, finding parts later on…etc. Converting to OBD1 allows you to use a stock ecu and KNOW that it’ll run right, parts are easier to find, more available and compatible with newer cars, and the biggest benefit is that your tuning options are wide open.

Since your engine came with the wiring, dist, and ECU you’re basically setup already to convert to OBD1. It’ll be easier to source the conversion parts you need than it will be to source an OBD0 ecu and distributor.

Read my write up on the conversion and feel free to post or email if you have any questions.

Colin is right about making the jump to obd1. I managed to get by with obd0 since I know what it take to keep it going. I never did have any issues with my set up other than a leaky rear breather box.

My car was stolen and found 3 days later as a non rolling shell. Winners don’t quit so she’s back as a sleeper now.
