Ok, I've been searching through the forums for most of the morning for track applications, and I've found tons of "Oh, yeah, gotta boost" posts. Originally when I started thinking about building the Sol up it was going to be a fun semi-dd/weekender, boosting the current D to about 210 whp, 7-8psi on stock internals, until one of my friends took me to a NASA event.
So, I've switched and I'd like to make the del sol a track car. I don't know much about engines yet (But I am learning rapidly through several forums and books), so I thought I'd ask advice on here.
Current auto - 95 Civic Del So Si (D16z), 109k, 5 speed. All stock with the exception of short ram and altezza taillights courtesy of the teen I bought it from.
Goal - Competitive track car. NASA classifies according to mods, weight, etc. so I should be slotted in with other cars near my own level. I understand already about upgrading the suspension, tires, etc. I'd be doing the time trial/time attack races.
Conditions:
1) Naturally aspirated. It's been pointed out to me by some of the more experienced racers in the Honda section here in Phoenix that a turbo'd D would probably blow up pretty quick on the track. It'd be fine for dragging, but I'm not going to be dragging.
2) Fairly close to drop in, if possible, and I'd like to keep the AC/PS, since I will be using this off the track occasionally as well, and no AC in Phx in the summer just sucks.
I'm still not sure of the difference between horsepower and torque. Torque is how quickly you can accelerate (which would be affected by things like chassis flex), and the horsepower is the upper limit of speed? (Someone described it as torque is how hard you hit the wall, horsepower is how far you go through it)
Given that, I've been looking at some of the B18 series because of the 127 torque. I like the CRV motor at 133 torque, but I believe because it's classified as a truck motor, it won't pass emissions for street in a Del Sol? I've also looked at the F20B long block, because of the torque/hp/price combo, but I think there is some bay shaving/cutting that has to be done, and you lose the AC/PS? Or can they be relocated?
In a perfect world, I'd also like it to be around 180-200 whp when all is said and done.
And the big one, budget. I'd love to keep it under 3000, I'm expecting 4000, and I could stretch and save if it had to be 5000. Since I can race with the stock engine for a while, saving a little while longer to do the swap right would be ok.
So, given all that, what would be the general consensus on a good swap for the track?
