Here's a link to a shop that does the LT1/LS1Rx7 conversions. http://members.tripod.com/~grannys/rx7.html
Scroll down to about 1/3 page and you'll see the part about the 9 RX7s here i'll just paste it.
And to the person saying it's gonna cost alot...it really doesnt. I think a kid on H-T said he totalled it out to about 6k not including the car. So if your doing an FC then it'll be around 7-7.5k for the whole project. I think the bolt in kits that sites sell cost around 2500-3000 and then the LS1 is gonna cost you about 3500-4000 for a long block
...Think the v-8 will forever ruin your handling? The August 2005 issue of Grassroots Motorsports Magazine will feature quite a few V-8 powered RX-7s that entered their $2005 Challenge event in Florida. The premise of the event is to build the best handling, best appearing, and quickest car possible for a total budget of $2005., including the price of the car and all components. You will be surprised at the wide variety of entrants and how creative they are. Check out the August issue for a feature on this year's challenge winner, a FORD POWERED 2nd gen RX-7!!! For a free copy of the magazine or to check out this year's $2005 challenge results, go to the Grassroots Motorsports website.
In the 2004 event, of a total of 76 cars that participated, a total of 9 RX-7s took part in the event, 5 V-8 powered and 4 rotary powered. In the drag race portion, all the V-8 RX-7s finished ahead of the rotary powered cars. No surprise here. The quickest V-8 RX-7 recorded a 12.636 ET, the quickest rotary's ET was a 14.323. What DID suprise a lot of sports car people is the results of the autocross competition. The quickest RX-7, a V-8, finished nearly 4 seconds ahead of the quickest rotary version. Among the 9 RX-7s present in the autocross, V-8 power captured 4 of the top 5 spots. Don't listen to those who tell you that a big V-8 will ruin your handling!!!
Daryl Evans's ZZ4 powered RX-7 solo car was last years local, regional and Canadian Western Champion in E Mod.
4 SECONDS AHEAD OF THE FASTEST ROTARY LOL 4 SECONDS IS ALOT
