GTM Performance Engineering: MHI Twin Turbo Official Release

Alstann · 01-05-2014, 11:33 PM

Im still fully in, waiting patiently. I really do have lots of faith that this will be a great turbo kit, but every week I swing closer to ringing them up and cancelling. I have the funds, abd I want to be turbo'd.

Last week was the last week for me. I am out now just have to wait for the refund.

Yes, paid in full

BlkNismo · 01-06-2014, 01:38 PM

Ever since I bought the Z in 2011 I had plans to go forced induction.
My end goal was to have install/tune done by March 2014. I slowly picked up all the supporting mods through out year 2012 and early 2013 (nice parts pile accumulating in multple closets)
I purchased the gtm kit July 2013. If it gets delivered my March then everything will be right on schedule.

can u share your list of mods you plan to do?
I'm still in the process of figuring waht's essential to support this kit (more specifically the due MHI kit).
As far as I understood it lacks an oil cooler but ought to be safe for a stock Z?
Cheers

BlkNismo · 01-06-2014, 03:35 PM

^for starters

32 Row Oil Cooler
Clutch/flywheel/csc
1 step colder spark plugs
Intake plenum gasket
exhaust manifolds gasket
misc fluids
Electronic Boost Controller
downpipes/test pipes
catback
Gauges
Bigger Radiator

Ah yes sure, common sense, even to me

Thx m8

The choice of exhaust is still my greatest cause for headache.
Naturally I'd want a 3" catback to maximize turbo efficiency, which I only know the Greddy Turbo Ti-C has. But I don't like its sound. In fact, I haven't yet found a single Z exhaust with the right noise. I've been heavily pampered by ferocious VTEC screams of my nitrous battered Stage2 3/4 Race motor and look for a good race noise for my Z. But working on a £3k Honda is a different matter. I wanna leave my Z engine untouched. And test pipes are no option towards that goal. I got to be able to pass M.O.T. of course.

I believe the Greddy TI-C is 2.75".

Fast intentions makes a 3" exhaust setup.

That is accurate.

I tossed around the idea of running full 3" turbo back, but it being my primary car, i dont think i want all the noise associated. was very close to pulling the trigger on the fast intentions exhaust.

I have since sold the gtm downpipes and have the z1 testpipes and will run oem nismo catback.

Should be sufficient. Dont plan on running more then 7psi with stg 1 gt28's on stock block.

Not quite, the Greddy Turbo Ti-C comes as 3" as featured on Nissan's Project Z car, the non-turbo Ti-C has 2.75".
Would be interesting to 'hear' the 3" F.I. exhaust. It's non-resonated? Though, I only find the 2.5" TDX catback on their web page with a video of the (very quiet) 12" resonator option.

Would you consider the downpipe or test pipe to make more noise? Don't u have emission problems with the TPs?

Mkai0 · 01-06-2014, 07:18 PM

I'm supposed to get my refund today, We'll see..

The turbos really quiet the car down, and if you are still concerned with the noise level you can go with their HFC option that is located in the lead pipes to make it even quieter.

Yep. Between the turbos and the catted 3" FI exhaust, mines pretty quiet at anything other than wot.
