In the states a company sells a plate that alows you to fit a subaru engine into a beetle, you use the VW 4 speed std box and just bolt them together. I believe it is not a massive job to fit the engine but wireing cud be another story! Rick
If u want it to pull wheelies stick a cozzy engine in it.
I stuck a pinto in the back of an old VW type 3, easy enough to do and performance was adequate, 55 bhp for vw engine and 105 for pinto provides an adequate improvement. A cozzy is just a glorified pinto anyway.
Talk to people who do grasstracking, they use vw gearboxes on their vehicles, powered by cozzy, honda and vauxhall units, im sure they can point u in the right direction.
You don't need to worry about engine swaps. The flat four lump can be made to pull the front wheels in the air easy enough.
BTW 'Prince of Darkness' was a beetle drag car that could run 11's in the 90's ...that was 1641cc if I recall (Met the guy who built it......clever guy, secret to his times were high revs and low weight). Get on to google, a few names to try are John Maher Racing (UK), Berg (USA) etc. Try lowbugget.com for some good tips.
Try some of the bug forums here in the UK too.
If you wanna go quick........get as much weight off the car as you can. Gearboxes are strong but you'll need to alter the ratios as theres quite a jump between 3rd and 4th (some people just keep it in 3rd through the traps....8000+ rpm!) an lsd helps too.
Make sure the front has plenty of castor - you can get spacers for the beam to do this. Try and get hold of a disk braked beam if you can. The IRS type rears suspensions are best but if your mates is swing arm he'll need to raise it slightly so that when the rear squats down the tyres are upright.
The engine can be stroked and bored up to ~2.4 litres with an aftermarket case. ~2.1 litres is the most with a stock case.
Theres huge amounts of goodies for the flat four engine - search and you'll see.
My mate has one with a scooby WRX lump in. Physically it fits in very easy, all you need to do is buy the relevant adapter plate and flywheel, normally from Kennedy Race Engineering in the States. The weak point becomes the gearbox when you start putting that kind of power through it though, my mate had £1K worth of gearbox in his car, and although the gears were fine he actually snapped the nose cone off of the gearbox by trying a 3K rpm launch at Santa Pod :O
The hardest part to do is the wiring, as the standard ECU has something silly, like 400 wires in it because of traction control and all the other useless stuff. This has to be trimmed down to 130 that are required to run the engine, takes a fair bit of time and effort, but the performance is something else! My mate has had a Porsche Carrera from the lights before, which I think speaks for itself. If you wanna see some pics go to my mates site: http://www.volksdreams.co.uk
Must be getting confused in my old age.........Im guessing now your mate has the mexican built air-cooled bug right?
If thats the case just do what I said. The mex ones have IRS too.
They also have a cat and other emissions crap that can come straight off.
New air-cooled mex = rip out everthing and tune that flat four!
New water-cooled fwd 'beetle' = stick in a TT lump - get in touch with www.jabbasport.com for TT stuff (they can source engines).
opps, just reread the whole thread.....I am getting confused! Breathing in petrol vapours for too long I think lmao
