i'm considering upgrading turbo to something larger and have found a gt35r with internal wastegate, its t3 flange, and i am wondering if there is enough room for it to fit on my stock manifold in the low mount position, any help would be appreciated

thanks

Will need a spacer plate to clear the manifold.

But yep, can be low mounted.

I'm pretty sure this applied to RB20/25 manifolds if I am correct, because I know this is how it works on an RB30 manifold..

But someone feel free to correct me if I am wrong.

Basically because of the size of the turbo, front cover/housing, it will either touch the manifold or just not even get close, which means the flange on the turbo cant sit all the way up to the manifold..

A spacer plates sits between the turbo and the manifold flange to allow the turbo to sit a little lower down from the manifold, allowing clearance for the front cover to have space between it and the manifold it self.

Hope that makes some sense, if it doesn't I will have to bust out bad ass Microsoft Paint! And you don't want that shit!

if your talking about the garrett GT3582R-IW

then yes they fit fine.i was running mine low mounted for nearly a year, and have only recently changed to a high mount manifold due to my stainless low mount cracking. (as they do)

if your interested i have the spacer and custom stainless dump pipe you will require for installing it.

and i also have a stainless oil feed, and return to suit.

And then have it crack and have to remove/fix the setup half a dozen times... ye no.

Too much of a pain

im using a 250 dollar manifold.. ill make sure ill let you know WHEN and IF mine cracks :)

i know of a couple of people using them.. and they have not cracked in a couple of years of VERY hard driving..

willing to show me different ash?

well then speak to leigh at extreme turbo manifolds to weld you up one..

and

yes you can use it on a stock one.. you will needa punch a hole in it for the gate where it all merges (near where you bolt the turbo on) and you will need a space for clearence..

And then have it crack and have to remove/fix the setup half a dozen times... ye no.

GKTECH make a stainless manifold that has been personally tested by Greg on one of his track cars.

Took a good thrashing with a decent sized GARRETT turbo, constant abuse on the track with no issues.

He also does a lot of stainless manifolds for RB30 which have been running on some high power engines for a fair period of time.

I agree, some stainless manifolds are poorly made and are prone to crack, but some are good quality and do last.

Cast would still be the safest bet by far though.

    • Yeah, hard to find and a pain in the ass to change with the transverse engine. I’ve worked on a GTiR before and it’s not a job I’d ever want to do again. theres a company in South Africa that makes RS3 gearbox adaptors for the AWD SR20 including gearbox mounts, so I could modernise it and go a dual clutch with paddles. For now tho, it ticks all the boxes. Super cheap, can throw the kids and their junk in the back, and SR20 that I can turbo cheaply, a CVT that’s not a dog’s breakfast like the V35, and has 80% interchangeable parts with stuff I can source from the wreckers cheaply…. But it’s still unique. I love the wagon back of the Autech version. It’s cheap enough that I can buy another stock manual FWD Primera with SR20VE, swap the gearbox to the N15 pulsar short gear ratio box, swap out the brakes to the R32 ones I pulled off my 32, register it on club plates and take it racing. $1300 shipping from NZ. Heaps of parts and aftermarket builders for transverse SR20’s in NZ.
    • Hard to say, just pop the rocker covers off and have a look if you think it's cammed. You probably need to replace the valve cover gasket/half moons anyways.
    • From my youth: GTi-R clutch change is a massive pain. The gearboxes are fragile? But the car is super cool and I want one 😢 
    • Remember this is 1988 tech.
    • Driveline vibration is resolved. I ended up loosening all my engine mount and trans mount bolts, giving it a good shake then retightening everything and it's gone... Let's just say I was surprised that fixed it.  I've been happily driving it around again but unfortunately put zero time into my direct port/constant pressure WMI setup. I'm on vacation next week, so I'll try and finalize it then.  On a different note, I spent all week fuel/ignition mapping 2x 216L V16 engines. Turbo's were burning glycol and we swapped them out for larger units. We also had planned emissions testing on site, so I figured I'd be there the same week to use their instrumentation and massage any emissions issues out if needed. This was a first for me. Fuel management is similar in certain ways to automotive (i.e air density as load variable) but very different in others. It's all PLC based and AFR's are controlled by air and not fuel. They use a control valve between the turbo and air manifold to control pressure which in turn controls AFR's. Due to this, target AFR tables supplied by the OEM are in pressures and not mass which really through me off. They use air pressure vs fuel pressure tables. I also relied on an O2 concentration sensor the emissions team had in the exhaust. Ignition timing was also all over the place and we were losing a fair bit of power. They're now happily sitting at 16-40BTDC depending on load. We were making about 1600kw at 900rpm at 90% load. Engines were running a lot smoother as well.
