Have been reading about the V8's with limited space for turbos under the engine bay, so here's a hypothetical for you guys.

I know the N/A blocks wont work with the stock or most aftermarket Turbo manifolds since the 6-port manifold interferes and space is tight, in most cases requiring a custom intake and exhaust manifold combo to make it work...

I have two N/A cars and just for fun I might try to do a remote mount setup using the stock S4 Turbo outside the engine bay. Doing this allows for much easier fabrication of the exhaust flange to turbo and use, depending on the turbo location an electric oil pump, use water/methanol injection and the TII ECU.

Again this is just hypothetical but might actually try it with all the extra parts I have stored.

Any thoughts?

I think if you were to go through with all this trouble then you might as well go ahead and go for a bigger turbo. And if you going to go with a bigger turbo, then you might as well go with and aftermarket ECU. But besides that, I don't think I'm qualified to answer this question.

I think you should try it to see how amazingly crappy it is.

i've got an old cartech manifold, it lets you fit a T4 turbo and keep the NA intake intact. there is plenty of room for a turbo and the NA intake, it is just that everyone tries to use the stock T2 turbo and manifold

When I turbocharge N/A engines, I use the 6 port intake manifold and a short but fitting T4 exhaust manifold. Its less money to just setup a typical turbocharging system.

This guy could put his Turbo in the back seat.

or you could pick up a stock turbo II intake system and modify it to fit the 6 port block.

but you might be disappointed in how craptastic the 6 port flows with a turbo in this combination. it does spool rapidly and makes tons of power quickly. but the top end sucks big time, power peaks at 6k and then barely holds as the turbo runs out of breath, unless you run something larger than a stock framed turbo.

the last setup i did could barely squeak past 14psi and then rapidly dropped to 9psi after 6k and slowly tapered off after that, with the wastegate basically clamped shut and the boost controller at max duty cycle.

Well I do have a full TII swap that will get rebuilt using 9.4:1 rotors, and I am maby buying a 89 Turbo 2 Rx-7 w/ 89k miles

That being said I would love to turbo charge a 6 port as a side project while keeping the 5th and 6th ports functional just for fun, of course with proper fuel and timing.
