Default H6 Lowmount GT3788 GC8.

Have been doing this job in the last week.

Lower rad support removed. Turbo and collector fitted and levelled.



LH manifold goes low to allow for lower rad hose outlet.



RH manifold goes high to allow for dump pipe to pass under.



X over pipes and 3.75" dump.





Overall position.





Forward mounted Jeep radiator.

That is sick. My concern would be heat from the turbo heating up the coolant in the rad. Any kind of heatshielding going on that turbo? i.e. blanket, coating, aluminum/ti heat shield? Any other cooling concerns with that IC, would you mind letting us know what core that is? With such a low mount turbo what kind of underbody paneling are you planning on running? Worse placement for an intake filter than a CAI

Definitely looking forward to seeing this beast! Good luck!

So awesome. Great solution for cutting down the length of the turbo/intercooler plumbing. Between that and the displacement, that GT37 should spool really quickly for its size!

Might not have to drop the turbo manifold depending on how small his hands are and how much grip he's got... but definitely going to get oil all over it every time he changes it.

BEAST...haha love it man, and i love that its in a GC, i may own a bugeye, but i think the GCs are my favorite body, especially since i first saw the video of gobstopper. guessin you built the engine up as well, specs on the engine?

also as others have mentioned..turbo heat and radiator= not cool....literally hahaha, yes bad pun not really intended. but im sure with as nice of a built as this is you will properly address the situation.

GL on build

The engine is getting forged pistons and rods, the oil filter is just there for clearance purposes, there will only be an oil cooler adaptor and hoses and the filter will be remote.

Heat control will be sorted in due course, it is still a work in progress.

Does looking interesting, but I agree about the heat soaking issues of the IC and radiator and such. Wouldn't a side mounting option on turbo placement been more effective? What compression you going with on internals. Along with where are you sourcing them?
Last two questions. What are you gonna run for EM and will this be a track only car?

Been there and done that with side mounting a GT40 on an EZ30R. Very very difficult to fit in a RHD car. Lowmounting is stealth and keeps the manifolds short and the thickwall piping retains heat much better and keeps the heat out of the engine bay. The radiator copping radiant heat is not going to be an issue in my mind. The turbine housing and manifolding/dump are going to be ceramic coated and some simple heat shields will take care of the rest.

The car will be street registered and legal. Engine management is the usual Vipec V88.

I think the owner is going with CP's and Argo rods, same as the other EZ30R-T over here.

With the mention of RHD I would assume this is either a British or Aussie build. Likely the second.

I concure. Aus seems to be where all the H6 builds are happening lately.

Pardon my ignorance of turbo setups, but don't you need a wastegate on that? Can't wait to hear this thing.

Very nice build. The short plumbing should help speed things up. Keep posting pictures.

Thanks

Wouldn't the filter being so exposed pick up everything and get torn up pretty quick through dirt and what not. Also couldn't drive anytime theres water on the road. The turbo seems like it needs to be boxed off to help keep the engine cool and to keep the filter away from the elements. Other than that amazing build, I could only dream top do somehting like that

What are you going to be using as a scavenge pump for the turbo oil drain? Just curious, as most options out there seem to be very expensive.

Nice build so far...

VDO do a reasonably cheap scavenge pump. I believe it is OE for Porsche 930 or something.

Completed exhaust.





Wastegates.



Random shot.
