im in the process of collecting parts for a 16v turbo and have been playing around with the idea of moving the turbo to the exhaust manifold. why spend 2k on a exhaust manifold and another 2k for a intake manifold. the oil filter will most definitely have to be moved to a different location to make room for a wastegate. i did a search on this topic but theres not that much info.

doing some work on my brothers car and have the head off so i put the 16v head on and have a john deere tractor turbo laying around to get an idea if its even possible. here are some pics. the turbo would sit around 3" lower. what do you guys think?

rear mounted turbos are useless IMO. major lag, more pipes to be ran to the front, not good when raining since water could get past the filter.

or maybe something like this

im not talking about rear mounted turbos. sry i need to change the thread title

This was at the Mille event in ATL last November.

What are you talking about then? I'm curious since I plan to give my car 8 more valves here in a few months, and I cant look it cause your pics wont display for some reason.

edit: the second set of pics loaded, thats a very interesting set up. How is the crossover routed in that scenario? what are the benefits and draw backs? seems like it would make routing even more difficult, but might allow for easier placement and indexing of a turbo larger than would comfortably fit in the stock location?

awesome thanks zeff. now i know that theres enough room for a down pipe. thats a cool setup but i kind of want the down pipe to be straight.

MooreBoost

so my pics arent showing up? there will be no crossover pipe. benefits are better efficiency for the turbo, cooler intake temps and probably more im not thinking of.

im trying to mount one of these

oh gota ya!

there really isn't room on the side, i'd love to get my turbo on the other side.
how much room do you have infront of your engine, like the pictures Zeff posted?
will the turbo fit there?

Interesting looking thing. Did you get more pics of the car?

I know Rod explored this whole thing a fair way into his 968 build. Check out the exhaust system! https://rennlist.com/forums/968-foru...o-project.html
While there is the upside of less lag with this turbo positioning I'm not so sure about the downsides outweighing them. I wonder if you could sit the motor upright and lower it with a dry sump system. Then have the turbo away from the radiator and belts?

Zeff

Nope, those are the only two pics I have of that car. Maybe some of the ATL guys will see the thread, I think Josh B might have taken some pics of this car.

Interesting that they have gone to quite a lot of trouble in that 968 and stuck with 8v?

exhaust difference & reduction of major turns on a 951 vs a mid-mounted/low mounted turbo would be immeasurable from your ***-dyno.

I run a mid-frame turbocharger on my 928's, no lag, great throttle response: You cant merely "theorized via forum" that it won't work because the distance is too far & too much heat is lost. I've been doing it for 7 years on 11 different 928's: works great. The biggest problem you may face is controlling the additional heat in the engine compartment: gotta wrap the crap outta that those pipes. I think TurboKraft has a low mount passenger side exhaust manifold for 4v heads he sells: run an electric scavenge pump like I run: works fine. Mark

are my pics showing up in post #1? if so that how i want to mount the turbo. same position as in my pic just a bit lowewr.
