So I've been thinking to myself about how to reduce weight of my 1st gen CRX Si to be lighter weight, however my aspirations to do that might be a bit difficult do to the fact that the 86-87 Si is the heaviest variant of my generation at a weight of 1,978 lbs. I was thinking to myself about trying to improve the power to weight ratio to something like the C5 Corvette, however that is a very lofty goal. Getting some math down:
1987 Honda CRX Si:
Engine: D15A3
HP: 91
Weight: 1978 lbs
Power-to-weight ratio: 0.046006066734075
2004 Chevrolet Corvette
3,214 lbs
HP: 350
Engine: LS1
Power-to-weight ratio: 0.10889856876167
Now, there is no way any amount of weight reduction is going to produce that kind of power to weight ratio that the vette has with the stock D15A3 engine, even if you could drop the weight to 1000 pounds, you are at 0.091, so... not quite there yet, so a balance of weight reduction and increase in power output is needed.
Now, say if a stock B16A engine is installed, that's around 160 HP. Weight would need to be reduced by approximately to 1500 lbs.
1987 Honda CRX Si
1,500
HP: 160
Engine: B16A
Power-to-weight ratio: 0.10666666666667
Now that's basically in my mind, close enough, however, I'm wondering if you can even reduce weight that much. However there is another engine that could be installed, not sure if there are any off the shelf mounts for it, and that is the F20B, makes 200 HP, you could use an H2B conversion kit to possibly make it work.
What do you guys think? Is 1500 lbs doable? Or is there a more feasible solution?
