Thats pretty cool!!! I have a freind in Charleston, SC that has a Triumph Spitfire with a 13b in it, its known locally as the Trazda Abomination. Even though its not a 20b its still pretty cool. That gives me an idea, how about a 4 rotor in a Lotus 7?

What would be awesome is to have the 20b N/A sound like Logan's (Defined Autoworks)car. The Cobra alone turns heads but with the sound of Logan's 20b, people would be wetting their pants.

Hey Vince! Yeah! That would be cool alright. I would love for it to sound like Logans, but I think that engine is a PP. I did'nt have the budget to do PP. I will have to find out from Logan what he is using for exhaust components. On that subject, if anyone has any suggestions on mufflers ect, please chime in. I used racing beats presilencer and muffler on my Lotus 7 and I have been pleased with the way it sounds. I would also be intrested in what anybody has used for a radiator and oil coolers. I have a set of original 20b oil coolers and was thinking about using them with maybe the addition of electric fans. One thing that I do have the luxury of, is a huge engine bay that was designed for a BB V8. I think that the 20b is going to look tiny in the engine bay. Anyway let the pant wetting begin!

Well its been awhile. But the Cobra is finally in the garage. I heard from Ernst at Rx-7 World today and he almost has the engine finished. I need to touch base with Logan to see where they are with the intake manifold. I have a fair amount of grunt work to do as the chassis has some surface rust from sitting since 1992. LOL So if anyone knows of a good product to coat the chassis with let me know.

POR-15 for the chassis.

Also, get this thing running by April 19th and bring it to Deals Gap Rotary Rally.

DO IT!!!

There is no way that the Cobra would be ready by April, I do however have a 13b powered Lotus Seven that would be a blast on the Dragon. As far as the chassis coating is concerned I would like to have to do this only once and I am not in any hurry.

Either way, I am interested in this project.

this is very interesting.

the other day, I search youtube for a conversion like this, but I wasn't successful in my search.........my thought was: a conversion like this would really urinate off a V8 guy.......I got my eyes peeled on this.

The way the lotus looks, I am sure this will be a awesome piece of artwork.

All the best, and may you be successful in your quest
