aw hell yeah ... i got plans to find something more exotic

i wanna find a first gen with a 12a ... i know someone local who had one for sale but swapped it out for giant ford v-8 ... just not my style if i want a 7.

A friend of mine has a 85 with an 81 12a motor thats been built pretty well. It was a carbed turbo conversion but since blowing the turbo hes just went back to na. Hes got a full build sheet for the car including suspension upgrades. Has nice recaro seats . Was settup for scca. PM if you want more info about it.

Hey Guys, Don't mean to steal this thread but here's a concept you should all try to embrace...

Its kinda hard to judge a vehicle's performance just based on 1/4 mile times. I mean, think about it. An engine with less cylinders can rev up faster than one with more (ie: a 2-cyl bike motor revs up so much faster than a V8) So, when comparing this on short distance runs, of course a small quick spooling rotary will proove challenging to a v8. What the smaller motors have in acceleration, they lack top end. on the highway, a V8 will be able to crumble a small 4-cyl because of all that extra power available. Quick and light is the best way to accelerate. Now I'm also not discrediting the v8 and saying it can't accelerate like a smaller rotary or 4-cyl, it would just have to make up for its acceleration lag via pure brute force. Same for the rotary engine. I'm not saying it can't keep pace or even beat a V8's powerband at speeds over 100mph, its just the characteristics of these different motors make it hard to compare...

so thats the explanation as to why a lancer evolution down in florida rips on vipers, vettes and camaros all day and its a 4 cylinder? btw rotaries are pretty good on top end. (try driving a FD)

to everybodyout there that thinks v-8's are better than rotary's think again. Just of few turbo changes and fuel managment you can easily get 650+hp out of a rotary. Check out this web site they have the kits.

First of all i started reading this topic and had to join. I am on both sides of this arguement most of the time, but have to side with V8. My buddy has a rotary and it is FUN to drive. Shifting at 9000 rpm, quick, just over all fun. But anyone who thinks that a rotary will out run a v8 they are on some sort of drugs. i have a stock chassis car, with 8.5 inch slicks. it is a small block chevy, but it runs 5.20 in the 1/8th mile at 135 mph. The motor cost me bout 6000 to build and is done the right way. if yall ever find a rotary that can keep up yall let me kno and send them to tx. I will show them what a real hot rod can do!
