top mounted turbo exhaust manifold options

sr71sss · Post by **sr71sss** » Fri Mar 26, 2010 11:22 am

looking to see if anyone has made a top mounted turbo exhasut manifold.

Seeing that my swap into a datsun roadster has very narrow frame rails I can't fit easily the stock exhasut manifold that mounts turbo on the bottom.

I know that JGS has a DIY kit that is reasonably priced but just want to see if anyone has any other options out there, looking to mount a std size t3 turbo think disco potatoe garrett.

Bill hincher are you out there I tried calling you the other day?

What I did for mine was to cut an ebay t3 manifold at the flange, flip the flange upside down, and had it rewelded. Turned out fairly well for only paying someone 40 bucks to do the cutting and welding for me

Just make sure if you rock the ebay stuff you brace the turbo somehow to keep as much weight off the manifold as possible

well I like those manifolds that were suggested but those are big bucks and I really dont need anything but a simple log manifold with a T3 flange

I have one of those ebay specials too but I'm looking at just using the flange at best and start from scratch with some 90 and t's to build a simple log, I'm sure some of you are wondring why I dont want something that will build more power is that my project is at best 2000lbs and using 195 50 15 tires!

Power to weight ratio is going to be insane if I make more than 300hp-fun but dangerous at the same time

shooting for more instant boost power than big boost spiking power up top

project in question is a '66 datsun roadster

eh, I realy don't see the point of a 500+ hp setup in a light little car unless its a dedicated dragster. Yes you get a TON of power but a terrible powerband with a little itty bitty sliver of rpm. It's gonna haul arse no matter what, ever with a 16g. Might as well get as much power band as you can...makes it a better daily driver and (my opinion) more fun to drive.

OP, where are you located?? I have made a few manifolds but if all you are wanting is a log style mani with the flange on the top......................it isn't that difficult. I would be more than happy to do it for you.
