New Garrett Gtx2860R / 2863R / 2867R

Are the tomei REAL 3 inch dumps? That´s the only one I could find where you can see the custom dump pipes...but it was before the GTX came in.

Series 1 are 72 mm internally.

Series 2 are 68 mm internally.

[farch]

Meh, HPI's are bigger!!!

[Deano 1]

I've got the S2's, so 68mm they full into a 3inch full tuned length front pipe into a 4inch merge.

[AndyStuttgart]

I have to measure again, I think I used 80mm pipes and bends, so 76mm inside diameter for each turbo until the cat converter, then 88.9x2mm to the back...as the cat is the biggest restriction anyways.

That´s why I used two catalic converters on the GTR, and after the middle box there´s a 114.3x2mm pipe towards backbox + end, as this was the biggest possible diameter between rear axle and LSD

nicely done!

[AndyStuttgart]

What diameter is that? No middle or backbox? Surely no street car then

[R31Nismoid]

I can prove otherwise on my own car. do a bit of clearancing with a die grinder, wrap the dump pipe, done.

Give it 18months and then see.

I killed 2 silicone joiners on a low mount setup /w heat shielding over the course of 2 years simply due to radiant heat.

Sean has certainly done it right the first time. I'd never silicone in that area again.

[black bnr32]

Its twin 3" to 4" and the backbox hasn't been welded on yet, and thanks for the tip Nismoid - I'll keep an eye on it.

Spat a bolt out of the turbine housing on the rear turbo, so exhaust leak...

My fault as I only used bolts and washers to attatch the rear housings, as they don't come with attachment hardware.

Permanent fix this time with the correct half retainers from some other turbo's in the shed.

Next time I go on a dyno, I'll put up a sheet.

[Marko R1]

sorry to hear the news - looks like u pulled out the turbo's yourself...fun job isn't it?

i just bought a 12mm S spanner to get to the exhaust manifold nuts on mine

[GTRsean]

Yeah do everything myself at home including engine builds lol....

Yep twins are fun, 6th time ever on GTR's now....probably 4-5 times with engine in the car, stubby ratchet ringies are your friend

here are some pics of a local newcastle engine builder & his latest project.

gtx snails with a few other goodies...take note of the intake plenum & flux capacitor. absolutely awesome fabrication work!

[GTRsean]

A lot of work right there. Will be interesting to see how it goes!

[Marko R1]

Sure is a lot work in this project.

Another nice pic

I can see one of the goodies from here... that sneaky Newcastle fella!

Had a play with a nice GTR with a set of the GTX's (modified -5 front covers) last week we ran out of spark (see dip) @ 460rwkw on E85 @ around 23psi definitely good turbo s even with the hybrid front cover..
