Must be very satisfying to have brought it back to life and into the family

Thanks. Its been a lot of work but it turned out well. Use it as my every day car unless its storming down. The fuel injection was a mission so if
anyone is considering bike throttle bodies on a kent pm me and I can tell you all the tricks and lessons I learned.
I am planning on putting a zetec in there now with it dressed up to look like a BDA. Will probably run webers with injectors retro fitted.
In NZ the blacktop is less common and therefore about 3 times the price. Is there much of a difference between ST and BT? Apart from solid lifters and
different stroke bore etc. Ie is it enough of an improvement to justify the extra price and me waiting weeks for a good one to turn up or is a ST
going to be just as good?
I started a topic here, ill probably be asking heaps more questions about conversion

Very impressive work on your car. Even more impressive - so much space in your workshop (he said enviously!!!).
Looking at your chassis, I note that its constructed using RHS tubing. From several posts on this forum, (e.g
http://www.locostbuilders.co.uk/viewthread.php?tid=189601), I got the idea that Lotus, (or probably Caterham now), used round tubing for
their chassis.
Is/was your chassis original Lotus/Caterham?

Lotus used both round and square. My car/chassis was made in 1987 and is a pretty close replica (dimension wise) to the first Series 3 7s. Which is
not necessarily a good thing! I did a lot of modifications to the front end and also footwell.
The three main replica 7 companies here use both round and square with square making up most of the chassis. Usually use round on corners (like in the
boot) on crossbraces and bits that arnt covered by Ali.
Round is stronger and looks nicer, square is easier to work with and more than strong enough. So you just combine the two.
