Rear mount turbo CRX
Ok, so. . .
First off, I am in the process of building and ls/vtec for boost. That being said, I have recently fabbed up a B18B torque mount to use a D series A/C compressor in my CRX. A/C is currently installed on a B18B that I have in my car. As I was looking in my engine bay today and thinking how the hell can I fit a turbo in there now(?), I realized that I wont be able to. Even with a sidewinder manifold and an Odyssey battery in the fender.
So...
I'm thinking rear mount turbo. I'll run a DC header I have laying around, reduce the outlet to about 2" depending on the research I find out later (it's going to be mid next year before this will be done). What I think is logical to do for this type of setup may be completely off, and I'm looking for some insight. It would be logical to reduce the exhaust all the way back to the turbo (which will be where the stock muffler would sit) to 2" or less (right?) and ceramic coat the entire length and heat wrap it to keep as much heat in the exhaust as possible. the smaller diameter exhaust would keep as much velocity in the flow as possible to keep the turbo lag to a minimum...right?
I know I'll have to get an oil pump for the return and go get a custom feed line made. that's not a problem. My main concern is the exhaust diameter, and my interpretation of the physics of this type of setup...
I've already got the EG half size radiator. I looked at it, and thought about it. The only way I'm gonna have it up front is to do the "radiator under the radiator bracket" mod. That brace between the headlights. I've seen it done, but I forgot the name of the guy that did the writeup on H-T. Then, I'd be limited to a log manifold.
Still debating what turbo I should use. A 57 trim t3/t4 or a .48/.60 Garrett from a T-Bird...Looking for 350+whp
Please, feel free to throw some information or helpful links my way.
TIA!

http://ststurbo.com/universal_system This might help these kits are crazy, there not civics but they are really SWEET!!! Horse Power did a seg on why remote is better because more dense exhaust gasses and cooling of the air dew to pipe lenght. HOPE this helps

HP TV get's it's money from companies like STS to advertise that crap. If remote mounting of turbo's was the ---- cars would come that way from the factory and all the highest HP cars, and track cars would be using it... but guess what they aren't.
STS is a hack company. You can EASILY turbocharge a B18B/C in a CRX, I've done it personally on several cars, with a/c and without.

Re: Rear mount turbo CRX
One of the fabricators that works for STS turbo has a remote mount turbo CRX. I can't remember his name now, but he's had it on there for over three years now and had no problems with it. He also lives in Utah where they salt the ---- out of the roads.
If I remember correctly, his car does high 12 second 1/4 miles passes with a stock LS/VTEC.
Anyways, if you want more info and pics of his setup, I'm sure you can email STS and ask for them. The guy is really cool.
And don't listen to people who don't have any experience with remote mount turbos. There are a LOT of myths aboout them, most of which aren't true.
I say go for it.

Hey,
I agree with Wilcox - buck the trend and try something different. If it works, great! If it doesn't, that's also okay. Everybody is entitled to their opinion - all that matters is that you are happy with it.
Good luck!
