Twin turbo upgrade R33 GTR

[Mlads33]

Heya folks, 

Just got home from a drive and my turbos decided to shit themselves.

I actually had it up on the market but now it looks like that's being put on hold till the issue is fixed.

 

The car is in amazing condition and I don't want to do any big single upgrades or anything like that. Since I'm pulling them out may as well put something a little better in there.

 

Any recommendations on some decent twins that aren't going to break the bank?

 

I don't want to have to change the manifold or anything like that so it would have to be something that bolts straight in. 

 

Thanks in advance!

Either rebuild what you have by @hypergear, find a second hand set or 2860-9 upgrade.

Exactly. 2nd is quicker to do and might cost a little more, and you will get 20% more whoosh.

You'd be mad to convert a GTR from twins to single these days unless it is for genuine race only use

Just find a set of -7s or -9s bolt on and keep the boost low

This what you boys mean by the -9s?

Also, while we're here - since they're blown and the car is sounding like a hilux, does this mean I shouldn't be turning it on at all and tow, or is it ok to not hit boost and drive it to the workshop?

Usually when the wheel falls off the back it fill the exhaust up with oil so not a good idea to drive it

I wouldn't allow the engine to turn until you've verified that you haven't gotten a bunch of ceramic bits from the turbine going backwards from exhaust gas reversion. Letting off at high rpm you can see the manifold pressure reach high levels of vacuum.

Yes, those. That kit includes the slightly different oil drain fitting you need.

And no, don't run or drive it. Depending what has happened exactly there could be crap all through your oil. Also, it is worth having someone check it out and make sure turbos are the only issue, they don't generally die on their own and there is a chance they can do other damage

[r32-25t]

And yes that’s what we mean by -9

Nismo R3 turbos for the Nismo logo in the compressor housing. It adds 50 horsepower at least.

Why?

can always put the shit lag wagon twins back on. 

A weekend in the garage and it’s “as it was as Nissan intended” or some other dribble that GTR guys love to froth over. 

As Brett said, -7’s/-9’s or if you want a bit more poke a set of -5’s. The as it’s been for the last 20 years.

It's not 2010 anymore mate, the world has moved on. An R series GTR is no longer for making big power out of, breaking parts that can no longer being replaced, leaving in the garage for years, then repeat.

It is for keeping standard as possible, putting genuine nismo accessories and maybe some period rays wheels on, and shipping to the US when you win GTR lotto.

People don't have to like change but it happens anyway. Ask anyone who wanted to own a GT Falcon or even a Torana in the last 20 years.

Removing or installing the twin turbo setup with the engine in the car is a pretty miserable experience. I have no idea why anyone would bother with that.

Since the turbos are coming off, might as well pull out the motor for ease and at the same time add in a head drain/sump breather, Nitto oil pump, extended baffled & gated sump, fresh bearings, ARP stuff top to bottom, Nitto OR Tomei head gasket, all fresh seals.

If money permits, a Samsonas too.

Who the f**k pulls the engine out to change turbos? I can have a set of turbos out of a gtr in about 2hrs,

better ring maatouks, crd, jem and etc and let them know what GTRs are for now because they’re building more then ever and finished examples are fetching huge money

It was more aimed at the post above yours where they recommended to pull the engine to change turbos

A lot of workshops I talk to don't even do intake plenum/collector with the engine in the car.
