NEW Garrett GBC22-300/350: Ultra-high response S15 turbo killer?
Every now and then I jump on the garrettmotion website to check out turbine housing options and such for their latest models. Looks like they just came out with an interesting lineup of very small turbochargers with the latest aero, but journal bearing center sections and ductile iron housings. The two that particularly caught my eye were the GBC22-300 and 350, very small rotor groups capable of 300 and 350hp respectively. These seem like the perfect unit for someone looking for something like an S15 turbo, but with better response and higher output. Looks like retail is around $900 too, so really a bargain all around!

Hahaha, the turbine flows another ~1.5lb/min of air over the 2560 too!

Oh man, one of these would be sweet for a low power seat time drift car or street car. If I weren't trying to purchase a house I'd snag one for my S13!
Have a VG30DE laying around for my Z32 as well, a pair of the 300hp rated ones would surely make for an interesting TT setup! All of the twins capable of this power will run you well past $2500, but these make a compelling option for under $2k and probably outperform the competition in every aspect! Oh man, they are oil cooled too which could clean things up on most simple setups! Not that two coolant lines on an SR cause much headache, but the engines that originally don't have a coolant feed/return it is a huge plus.

this would be killer for a stock block sr20 with MHG, cams, 740cc injectors, etc

Right? The only thing that would need to be checked is if the compressor housing can be clocked correctly to clear the stock manifold with the wastegate actuator where it is. I don't think it would be an issue with aftermarket manifolds.

I've been searching for a .64 a/r 2871 for a little now and have pretty much only been set on older period-correct turbos but the performance, SR compatibility, and price have peaked my interest in this piece.

I've sold one and checked it out in person. Great quality I've yet to see someone install it though.

1: it def needs to be re-clocked, both so that the compressor outlet points the same direction as a normal t25/28, but also so that the chra oil drain is on the bottom instead of on the side 2: the WG actuator uses a bent rod instead of a straight rod, how did you orient it so everything lines up correctly? I can?t see how it would work without chopping the rod and welding it back together, or somehow twisting the rod in the diaphragm housing, which I?m reluctant to try. 3: did you have to weld an extension on to the compressor outlet? I?m reluctant to put a silicone coupler that close to the manifold |

It definitely had to be reclocked. I had to twist the WG rod a hair, and it is maxed out on its adjuster (as I have it installed). I used a t28 drain that i had to modify a bit. I am going with a silicone 90 out of the outlet for now. I am a bit hesitant on that as well, but worst case I will just weld a 90 on to the outlet. Shoot me a message on IG @krustycoupe and I can send you some pictures. Havent had time to host images.

Looked in SR POWERED facebook group (awesome resource) and couldn't find anything. Also curious to see how this would do on an SR.

I spoke with my Garrett distributor and he said it is gonna be a bit small for an SR and fall off pretty hard on the top end, they were mostly designed for powersport applications. Ended up going with a GTX2867R and still very responsive and makes great power

I've always been a fan of a properly sorted SR with S15 T28 BB, but i'm down to experiment with newer tech and see what comes of it. Crazy to me that an SR is still a relevant and competent engine in 2022 with the right tweaks. Saw a 1767hp billet SR drag car the other day and it still had a factory crank lol

Please do! My friends over at Whalen?s Speed just ran one on a Can-Am and it made 340hp at the hubs on race gas (expected to make 360 on ethanol). So we know the compressor works as intended. It?ll just be a matter of which wheel hits it?s limit on a two liter first.

I'm looking for 300wheel with good response, so it made sense. Are they running them with the internal gates? No issues to report with being able to bleed enough exhaust?

This is probably a big pic, but here is it next to a Gen II 2860.

Literally just that. It adapts from the 5 bolt flange, to vband for ease of serviceability.
