3/71 is too small for a rotary you should look into using a 6/71. I've heard they can be tricky to get a tune up in Ive never had a go. There is an rx4 wagon from NZ on here that runs a 6/71 and seems to go really well.
yeah iv been chatting with that dude and looking to buy his 6/71 if the 3/71 wont have enough huff. but im not going for mega hp from it just something differnt and that will do a good burnout haha
Been done back in the late 80's, Phil Alexander built 13B PP with a 3/71 that was fitted into the yellow RX-3 sedan BABY1, albeit with a carby, but I don't think injection is going to give you much extra anyway really.
The reality was that the car was also slower than other cars with aspirated 13B Peripheral Port motors.
Bill Nabham also had a 3/71 equipped RX-3 Coupe MADNES back in that same period, but fitted with an extend port motor, and was arguably just as quick if not quicker than BABY1. Here's some vids of it at Oran Park back in the early 90's.http://www.youtube.com/watch?v=wHMSB42DQEshttp://www.youtube.com/watch?v=VUoWOxdiqcA
General opinion is that for ultimate performance a 3/71 is too small. However it really depends on how much power you are looking for and for what purpose? Bills RX-3 MADNES would have been a genuine low 12 second car in "street trim", maybe a high 11 on a good day, so you are still looking at something reasonably quick, but, it has to be said aspirated BP's and PP's are going quicker so it's very much a looks over performance option to a great extent unless you put a lot of research and effort into making it all work.
thanks man yeah i was thinking the 3/71 might be to small my only problem is fitting it into the 1300 which can be a mission due to the size of the engine bay and have to keep to all to warrent and cert standard so it can be driven around the streets here
