I have a 13b rotary in there now, but may be switching back to Toyoya...I'm sure most of you diehards will be pleased with that. The rotary is nice because of the weight aspect and the RPM's. I'm not concerned about period correct or anything. Something good for track and street. I'm sure there are a lot of different opinions but are there 6-cyl. that fit but still light and how much more work is it to get it to fit? Is it worth it from those that have done the conversion.
Or better to go 4-cyl, (turbo/intercooler) etc. Just getting ideas. I've seen a Mazda RX-4 with a Toyota 2JZ-GE (But not sure how that would handle on the track with weight). The Orange one in pictures.
Open for suggestions, again, doesn't need to be period correct, modern ok, probably better, track use and street, weight to HP main concern. And would need matching tranny 5-sp or 6-sp. Or stick with the rotary and just work on tuning that. Currently 13B GSLSE Street port with 48 Weber Downdraft IDA. matching 5-sp.
