ive seen a decent share of 13b's around here now, and ive got around 4 grand to spend on my little 1rst gen. im sorta new to the rotary dealio, and even more so with carburaters (sp?), but ive seen the setup from rotary shack that basically swaps in a 91 turbo 13b in and some mild needed parts, including a weber 45mm carb that kicks out a lot of power

couple questions:1. where, or could you have an intercooler? can someone explain how you replace the existing setup for the weber?

2. labor shouldnt matter, but 4k is reasonable, correct? im basically talking everything getting mildly upgraded except for porting, ill save that for later. (the clutch, flywheel, downpipe, all that is what i want)

3. is it an easy swap? i really like the fact that if i get around 200whp, or possibly more (trying not to be too optimistic) that it should be a little rocket.

thanks for the help

 

Just talk to the guy that runs the rotray shack. If thats what you want to do.

 

Do a search,... this stuff is all over the board.

Have you thought about keeping it fuel injected? You can pick up a Microtech Lt for around 850 these days. Your wallet will thank you (gas prices aren't getting any cheaper). I guess if you aren't gonna drive it as a daily driver milage won't matter, after all it's gonna be a high performance rotary beast!

 

the only reason i havent though of keeping it fuel injected is because it will be my weekend car, and because i heard that the weber really helps it pickup a lot of power... can someone explain how you change from fuel injection to carburation? ive seen it done but vice versa (carb to fuel inj)

ill look through the searches for more info, and thanks for the replies

 

The Weber is probably the least expensive way to make horsepower but you can get just as much if not more power (and torque!) from a '89-'91 intake and an aftermarket ECU. Driveability can be much better with the 2nd gen intake than what you will typically get from a Weber also.

I had a 13b with a Weber 48IDA and liked it, I switched over to an S5 intake and Haltech F10 and LOVE it.

 

i agree i was 13b with weber 48IDA it was snappy, had good power

 

IMO, Holley is much easier than weber's. I have had both Holley and Webers, and the Holley's are more straight-foward with me.

Purple's right on, I searched for info on the carbed set up prior to purchasing my microtech and in addition to horrible gas milage, all of the shops I spoke with said I would get a much better powerband with the fuel injection (especially torque). I then looked into one of those custom aftermarket intake manifolds for fuel injection that they sell in Australia but those shops that sell them steered me away from them saying they were more suited towards race engines and convinced me to stick with my stock series 5 intake manifold for my intended use of the vehicle (daily driven and track on the weekends, not drag. From my research, running fuel injection is no more expensive than a carb set up if you don't go overboard and get a motec or something super expensive like that. Most of the turbo carb set ups seem to run 2500 and up (I still haven't figured this one out, maybe the price comes with a great turbo, exhaust, blowoff valve, wastegate, ect.) Even the most basic efi system will be worlds more advanced than a carby any way you look at it. Whatever you decide, It will be better than what you have now right? Just some food for thought

FYI, some of the guys on the microtech board are claiming up to 25 mpg on their vehicles once they got them tuned (this is normal driving ofcourse and not flooring it).
