there are 1000bhp sr20det's
the problem with the pulsar is the transmission, once you sort that, the engine when worked properly is plenty good enough for more than enough power
problem comes down to money...£5k plus for gearbox, £1k plus for a clutch, £1k for diffs if you can find them new, 1-2k for prop, upto £6k for driveshafts.
at cheapest a decent transmission set up, that should take the power you can get from the engine and actually put it onto tarmac is going to cost you approx. 8k
most owners wont spend that kind of money, thus very few dedicated drag cars.....infact none at this precise moment of time.
theres plenty of research work going into them, you just have to know where to look and who to talk to...
