What motor for carbed sandrail setup
1 Attachment(s)
This is my first post and I am totally new to rotaries. I have a sandrail that right now has a 1915cc aircooled VW engine with a non-intercooled turbo on it. I want to go rotary, but don't know what to buy and most importantly where to buy a motor from. The car weighs 1400 pounds and with the gearing in it I am doing 60 mph at 4000 rpm in 4th gear. 1st-4th are all super close together. I am a firm believer in the keep it simple philosophy. So a carbed NA setup (using premix) would be my first choice. Probably with a Holley offroad carb. Right now my VW will only rev it out to 5500 rpm.
Which motor should I get? Which port job type should I get? Who should I get it from? https://www.rx7club.com/attachment.p...1&d=1194133390 |
welcome to the board. :)
non turbo 13B definitely. you can get a Weber setup for it. porting will really depend on what kind of power levels you want and what your tranny will handle - 60 MPH in 4th kind of makes me uneasy for an engine capable of 8000+ RPM. anyway, you would need to know what neighborhood of HP you want, then decide on which port. on a sidenote, why not just work on tuning the air-cooled VW engine? you'll keep weight down right off the bat by not having to deal with an extra radiator (i will assume you have an oil cooler on it somewhere, if not, get one) and all the fluid and piping it will need. parts to hook up old Dub engines are pretty inexpensive if you do the work yourself. either way, looks like a cool project. have fun. be safe. :) |
