Ok, I have read Posts From Soletek, and Bunger. It looks like I am on the same band wagon, just a little behind the power curve. I have fast cars, but this started about 2 weeks ago, talking with a buddy, and trying to get him to get a car with better gas mileage, due to how much he drives. Anyways, one thing lead to another, and I was going to prove my point, that you did not have to buy a hybrid to get good gas mileage. Well, I found and got an 89 CRX CX, with full body mods for cheap, but with no engine or trans. I thought I had a D15Z1 Engine and trans from a VX locked down for cheap, but the guy did not get back to me, so I called a place in WA who brings in the JDM stuff. What I am trying to figure out, is which is the better way to go as far as trany. The HF gearbox, or the VX. I want to get the best Gas Mileage, and it looks like Bunger is getting great mileage. I never saw what Soletek finally got. After doing some research about the HF and VX engines, it looks like the HF til 89 was 60 HP, then the 90-91 had 72, but in 92 the VX went up to 92 HP with 98 Ft/Lbs of torque. I figure I would go with a turbo, just so I make sure the car can get out of its own way if needed, plus, I will be using the car to haul my daughter's gokart. So, any input about trans, and any issuse on what mounts have to be made for this conversion. I might be trying this with a Del Sol down the road, but need to start getting rid of some of my P-Cars.
