I was looking at my car today and thought of an idea for a TT design that would be different from the conventional Greddy or APS style. Instead of mounting the turbo's down low, how about doing a twin turbo in the T-netics style with the turbo's up top in place of the current air intake boxes. It would make sense with the twin t-bodies to run something like this layout. Any thoughts??

I still think it would be much easier to do a conventional lower manifold mount setup, due to space constraints.

From the HR dissection thread, Sharif did say there was more room for piping long the sides of the motor. This is what got me thinking about the design. The only real re-location you would have to do would be the power steering resevoir in the passenger front. Other than that it is quite open, much like the drivers front side.
Flipping the manifold around would not be as easy as you think. This would require remounting some of the belt driven components. If you took the A/C out and remounted the P/S on one side and the alternator on the other side (who knows, maybe one of those components could stay mounted how they are now and have clearance) then you could do this. However, this would also require you to make new belt idler pullies most likely depending on where they were located and if the belt couldn't be run straight to the unit.

Yeah, I don't think changing the belt system is an option. I would think it would have to be a similar system to what T-netics uses to get the exhaust up to the turbo and back out again. Intercooler set-up would be something similar to JWT with inlets and outlets on both ends of the unit. Maybe a dual intercooler system.
i doubt the piping is the hold up.. any big company like Greddy could sort out the piping in no time.. its probably the EMS ... but one would think since the F Con completely drives the car itself.. it should be able to do that.. but maybe the harness is diff

See VQ35HR dissected thread for details.The HR kit just requires custom/modified piping changes, and a new EMS harness..that's about it.

I'm thinking of a completely new TT design that would look and function great with the new HR twin t-bodies and take advantage of the newly created space from the current twin airbox locations.

Making some custom manifolds isn't as hard as it may seem. The right shop should be able to do it no problem.
And yes, the EMS is the big holdup.
I agree with you taurran that the PS would be a problem. I would just mount it like Phunk did on his car and use the 4-rib section on the crank pulley for the PS after you remove the A/C.
i think the AEM would be the way to go with this setup just build a custom harness.
would be cool to see the turbo's in the engine bay.. but realisticly what about a rear mount setup? like STS but with twins?

Remember guys the HR has a completely different belt and accessory system than than the DE motors. The only real problem in the passenger front corner is the power steering resevoir.
