Re: First car and first project.
Hi Ally
Well the minimum you are commited for is a head overhaul, or better a TC head. The TC has individual inlet tracts, so could really carry anything you wanted - up to four throttle bodies or even a pair of DCUE's.
A K series transplant would be good sport, but my instinct is that you would need to spend quite a lot on it berore you fiited it - at least the head gasket and through bolt upgrade. So it would be a much bigger project than just an engine swap. And getting a rear drive gearbox onto it could be tricky.
Much better would be a T16 transplant. This engine is essentially an O series with a 16 valve head, so can be easily converted to lengthwise using the sump and gearbox etc from a Sherpa van. In multi point injection form I believe it is good for around 140 bhp so wont be a slouch. If you can get hold of a Turbo variant it is a seriously nice motor. But there are a few issues with the front end of the turbo to turn it through 180. Webmaster Richard knows about these, so no doubt he'll reply. Again, the standard rngine could easily be run on DCOE's to avoid engine management issues, but it might be a good idea to do a trial lay up of some carbs to judge whether there is enough clearance to the inner wing.
Once you've upped the power you're likely to want to run a V8 diff, both for strength (extra planet wheels) and to realise the top speed - a bit of a screaming sprinter otherwise. And you'll defintely want to do something about the front brakes (V8 uprights and calipers are a straight swop) - but your Dad can help you out there.
