GT35R Journal Bearing?
 

My friend bought this turbo and never used it and ended up getting a ball bearing GT35R for his evo instead so he said he'd sell me it for $350...

Here's what he said about it:


The specs are generally identical to a normal gt35r turbo, it has a .70 ar compressor housing with a t31 turbine housing for compact engine bays which is .63 ar not ball bearing but a regular 360 journal thrust bearing but you can upgrade the chra to a full steel ball bearing if you want,

And he said it was both water and oil cooled if that matters.


So my questions are:
Is it a good deal?

What kind of power/spool can I expect with it?

I'm currently running a BNR stage 3 turbo with a 3" all the way to 2.25" duals (Greddy Power Extreme).2.5" intercooler piping to a nice big front mount. Microtech lt8s ems, stripped emissions, a/c, ps, etc...

I dynoed 300rwhp @ 11psi with exhaust leak, intercooler leak, ignition breakup..

Fixed all that but had to switch to a stock exhaust manifold (SSAC had small cracks :() and still can't get anymore than 14.5psi out of it with the adjustable wastegate spring..to top it all off I don't get peak boost til nearly 4000rpm....

So I'm looking for something with quicker if not the same spool and more power. If this isn't that great of a turbo I'll just end up getting a Masterpower T70 instead...so yeah opinions? facts?

I've got an aspec version of the GT35r in plain bearing form. They call it the GT3574. It supposdely has a slightly different turbine but I really don't know to be honest.

IMO, the turbo will work well - but not with that turbine housing as its much too small. I also don't know if the turbine wheel in that plain bearing, garrett standard, turbo would be smaller then a regular p trim or not but if it is smaller.....I wouldn't use it.

But $350 for that turbo brand new is a smoking deal. Buy another housing for ~$150 if the turbine wheel isn't too small and you'd have a decent little turbo for around $500.

The only "GT35" from garrett would be a 3571 it runs a much smaller compressor at 51/71, other than that I would question what turbo it is. The 3574 we make runs the 35 "R" 61/82 comp wheel mated to a 74mm turbine, water cooled CHRA non-BB.

Classic hows the turbo working out for you?

the .63 a/r is too small as mentioned. you need at least a .83 or so on a rotary. And obviously it wont spool as quickly as a gt35 BB. But even if you change the housing to a t4 exhaust housing with a larger a/r (.83-1.06) you should see full boost by 4000. and be able to get 360-400hp at around 15 psi. on stock ports (just guessing) and Provided it has a similar flow map as the BB gt 35

I wouldnt go journal. The BB significantly spools better

but if your looking into a journal GT35R... check out a T04s precision turbo

Really, really excellent. I moved from a T04-R to this turbo and its working very well. Transient response was much quicker, although the R seemed to pack a little more punch at lower boost levels. They're probably terrible to compare back to back given the huge differences between them (plus I ran a 1.00 on the old one vs. .84 on yours) but nonetheless....thats my story and I'm sticking to it :lol:

To be honest, in comparison to a local's FD who runs a BB GT35R, my plain bearing (a-spec version) is almost identical in response, although mine holds boost a little farther up as the FD is running a .81 open valute and peels off 3-4psi (from 15) by 8500rpm

I'll look into the brand and such that it is.. just haven't had the chance to stop by his house and get some pics. I had a feeling the hotside was a bit small since I watched 3 friends get T70s with small exhaust housings and post lower numbers than my BNR :lol: but when they threw on he .96 They put down 400+ :(

I'll check out his turbo..assuming I do get a bigger hotside and end up with the turbo for $500 total cost, how does it compare to the T70? I know my friends are running their T70 at a little over 15 psi, but none of them have meth/water injection like I do. Anyways they are putting down around 400 rwhp and get 15 psi at or before 4k rpms with streetports. Would that mean I can get more power from a T70 than this GT35R?

Thanks

Yeah. But slower spool

But you said I'd get full boost by 4k with the journal bearing GT35R, that's the same spool as my friends T70s. Or was that figure on stock ports as well?

Oh i forgot we were talking about journal bearing. The t70 will still spool slower being a larger turbo. And yes i was refering to stock ports.

FAIL: It was an XS Power POS turbo lol
