Bringing this back to the new forum after quite a few requests

The project started back in 2003 when i acquired a coupe shell that was relatively solid from a Mr A for a silly price. The engine was a 8v SEH engine and after some thought, it was decided to keep this as the engine since no-one's done a well tuned 8 valve engine in this format.

The spec sheet grew as did the ambition. Unfortunately the wallet hasn't as yet and the car is very slowly being worked on when i have time and money to do so, but being a student dosser.. that proves very hard with a BMW 320i needing maintaining so i can work at the weekends at this place:

If you look in the gallery, that's a Group C Nissan... and yes i am working on that... Kinda a dream come true so you might understand what I'm getting to see and want to make this manta up to!

Anyway, spec is below followed by pictures galore:

That's as far as i've got so far, hoping maybe things will improve to a point where i can actually spend some serious time on the damned thing and really get the shell sorted out underneath before i start looking into getting it to a shop to have the roof sorted.

Blimey, been a few years since I was logged in here :o

Well, the Manta's been mothballed for the past few years due to work commitments at university, and for the past six months, job hunting. HOWEVER I did manage to get myself a job over at Aston Martin and due to start there soon. Once i've got settled in, I hopefully should be able to continue where i left off with this project.

I know it's been ages, but as always, life / work commitments come first :(
