aaaahh...what the ????

Really should be focused on making a tube frame IRS and IFS for a Fairlady!

then you guys would be crying that he cut up a Fairlady...

Hey if $ were no object, I'd be all over building a roadster using a tube frame, and a full carbon body. That would be superlightweight, and it would be a chance to better tune some of the rear suspension issues that haunt the real thing. Oh yeah, engine wouldn't matter either, but I think I'd still run a U20.

Will....... Will never fails to represent for us U20ers!.... WOOT WOOT for Will!

The U20 is an awesome engine that people continue to dog on. Its much like a Contenental GO-300 aircraft engine. People were burning those up as well until it was found that those people who were burning them up were also flying their Cessna 175 like it was a P51 mustang. People who flew in a more gentle fashon and took care of the engine found that they would go for a very long time with few issues. An SR DET would be cool in this concept since a real car wouldn't be cut up to make it fit, and the intake and exhaust could be routed in such a way that the current thermal and fluid dynamic nightmare could be lessend and real HP could be found. Also the body could be built to house rear wheels that would hookup with mega HP. I have some sweet ideas for this concept car, but it would cost so much that I doubt I will ever be able to do it.

Just a thought.

Hey Will, just curious as to what you mean by:

what nightmare and real HP?

I mean you have way too many angles and twists for really god flow. That and you have a ton of heat being generated in a very small area. If there were a little more room to work with, a few of the sharp bends could be removed, the turbo could be placed somewhere where else so intake temps might be lessened as well. I know you cant move it far from the block, but something could be done to lower temps in that general area. One could also set the engine back a little bit to make room for an intercooler. The thing I see now is that there is way too much restriction in the exhaust area, as well as a huge amount of heat. Its just a thought. I'm all for scratch building a roadster clone, but making it better. I just don't see the need to cut up a real one. They will be worth some $$ in the not too distant future.

Way too many angles and twists? There's a lot of generalizations in your message...

If you look at the stock Nissan routing, it is a really tortuous path. That is an aspect of all turbo applications, difficult to avoid. Now maybe not optimal, but I am not going to complain about only getting a 50 out of a potential 55 HP increase. Intercoolers create more drag than any other part in the system, they have to in order to cool the charge air.

It would be super easy to make a cold air intake fit on the roadster, for an SR20DET or any other application. If you are referring to my setup, I chose to have the intake in the engine bay because I live on a dirt road.

Placing the turbo in a more open area would allow better heat shields, but moving it a few inches does nothing for the bends and twists. Turbos are a compact device that require exhaust input, ouput, intake input and output (not to mention oil and coolant!). There is no getting around having all of that plumbing in a small area.

In the roadster, there is plenty of room for an intercooler, now in a 510 there is a challenge that could be helped by placing the engine further back and that is done on track cars, but not many street cars cut the firewall...

And way too much restriction in the exhaust area? Without meaning to be an ass, read Corky Bell's book on turbocharging a NA motor. There is a lot of basic info in there that can be applied for a good general understanding. See what size exhaust he says is optimal for a 200HP engine (the same size Nissan used)...

I agree that cutting up a roadster isn't necessary, making a clone would be cool, but is way outside my budget, capabilities and time allowed. If people are throwing away these cars, I don't see the crime in it.
