whats hillarious is your taking a front engine car and making it a mid engine car by putting the engine further back than the strut towers. That thing will handle much much better.

Thanks for all the help everyone. I've got a major issue to tackle now though. I've got a couple of pictures of the issue....anyone have some ideas?

Does that mean that the RX8 is a mid engine car, it's engine is basically behind the strut towers...lol

Your tire is hitting your fender? I don't understand what the problem is.

stezhead54 · 07-11-2009, 12:58 AM

The problem would be the fact that the tire is sitting on the bump stop right now, so i've got no where for the tire to travel but down. So i'd be riding on the frame, which is not something i really wanna do for a daily driver.

stezhead54 · 07-14-2009, 10:12 PM

So I've come across two more questions about my install. They can both be answered at the same time though. They would be...which set of injectors are the primary, and which are the secondary? Also which rotor is considered the first one?

Raise it up a bit? Maybe some spring blocks if you're feeling ghetto

Primaries are located in the irons on the engine, the secondaries are in the lower intake manifold.

First rotor = closest to the front of the car.

Thanks....i'm all wired up now except for the coils. those will be hooked up and ready to go in a couple days. So it looks like things are gonna go pretty smoothly for the next week or so. I've got the engine out of the car again so i can weld in the engine mounts. Can't wait to get them built and in place :-D Then it's just exhaust, and drive shaft, and i'm set :-D

stezhead54 · 09-10-2010, 01:39 PM

For all those who are interested, the car is about 3 steps away from completion (drivability wise anyways). I only have to put in a small section of exhaust pipe, and some oil cooler lines, and finalize the gauges and wiring for the engine, ant it's all set. I'll be putting the updated pictures on here tonight when I can get to an actual computer. I've still got a lot of work to do on the car yet though. I've got dents and dings that I need to fix, along with the final paint job thats going to go on it. Then I'm also redoing the inside, so that's going to be some more work. I'm excited though, I'm actually able to see some progress.

NoDOHC · 09-10-2010, 10:59 PM

Have you had it running yet?

Is the 20B really heavier than the 305 that was in there? The suspension being on the bump stops would tend to indicate that it is. A fully assembled 305 weighs about 450 lbs, surely a 20B doesn't weigh that much... even with a turbo.

Now this is an interesting swap, I would like to see the finished product. The look on the faces of the American car guys will be priceless.
