Turbo now SOLD

Hey All,

Well today I purchased a new turbo for my R32 (RB20DET).

I have been told that it is the following, however he was not 100% as he purchased it as is...

R33 Exhaust Housing with Steel Wheel

Larger Wastgate - Unknown Actuator

Larger GARRETT Compressor housing with larger wheel

This came off an RB20 and was apparently a bolt up (other than an oil line that I was given)

Is anyone able to confirm this from the following pics? (Would be GREAT if you could tell me what type of Comp housing it is).

cant tell for sure but here are pics of a stock r33 turbo (by itself) and an hks 2350 (attached to manifold)

cheers skisII... how does yours go now? my Garrent housing look simalar (but I guess you would expect that :D )

Mine goes the same as before, i was not actually fitting the 2530 :)

i was fixing my exhaust manifold gasket and at the time a friend had his 2530 off the car so we were comparing :woot:

looks like its not ball bearing to me either! Dunno if i'd be putting this on an rb20!

well it was either this or a stocko r33 s2 turbo so for $500 it can't be any worse!

I believe it wend VERY well on the previous RB20 it was on so I don't know why you say that... Are stock turbos BB?

Really need to see it with the housings removed . Turbine housing is RB20/25 but core looks like water cooled T3 . Aluminium compressor backplate looks like TO4B , the compressor being 7/14 blade is probably the Buick Grand National TA34 299-4 . She's a typical bitza Hi Flow and the results are usually very average .

oh, interesting. Thanks for the educated insight... Having said that would you expect it to perform better than a stock RB25 turbo?

We will have to see how it goes, I just want to get a screamer pipe before I put it on...

if it's laggy as sin on your rb20 cat I'll swap ya my r33 turbo :(

ha, thanks for the offer Jaff but from what I have been told it worked well and I don't believe it will be but will update once it is on! should be about a month because I want to get a screamer first and will be doing my timing, water pump, pulleys ect at the same time!

series 2 rb20 turbo's are bb. Put it on and see how it goes, probably make good top end power but not too sure if you'll be too happy with the midrange. I wold probably say an rb25 turo is a far more user friendly turbo and very streetable for an rb20.

The rear wheel looks to be the same size and design as my old stage 2 highflow from gcg but mine had a bigger 6(12) blade compressor in it. I had full boost a bit over 4. I'd expect you should have something similar with your turbo, maybe a bit lower boost threshold somewhere in the high 3's.

I'll be interested to see how it goes

Well, I fixed up the coolant feed line (What a pain it was!) and took it for a run (YAY no leaking). Bit slow and no kick to it at 8psi so I wound it up to 14!

No wheelspin and has reasonable lag but pulls hard/solid. I would say I have more power now but not as useable... I am just about to go out and fix a small oil feed leak and will then take it for a real run and adjust the boost (I'd say 15psi before I get it retuned).

Not sure about it yet... Does have a LOT of top end though!

Will update when I have had a good run and play with it.

Not sure how happy I am with it really... Bit to laggy for my liking but does sound very cool! Once spooled up it goes off it's head but not good for off the lights or when you are in third and give it a punch it not responsive, you have to down shift. Think it comes in at about 3,500-4000rpm and full boost at 5000rpm.

I am already thinking about taking it off and swapping it for a R33 S2 turbo. I rekon it would go much better on an RB25!

Hmmmmm, lesson learnt I think. But will be much easier to do the swap the second time around. Might have to take you up on that offer Jaff! :D

Check the actuator is not the problem, being too long and holding the wastegate open.

Did you check that before you put the turbo on? I had a GCG on my 2.5 and it was as laggy as you describe, turned out the wastegate was being held open. Fixed that up, now nice and responsive.

    • Gday Thought it was about time I started a build thread! As expected this project has snowballed into a huge financial liability, but unless you’re strong willed and responsible, it’s not a surprise. Background -  My first turbo car was an R32 GTS-4, got my full license and then totalled my Au Falcon a week later, so while trying to sell my RMZ450 dirtbike to buy another car a bloke offered to swap the R32 which at the time I felt like I was ripped off but looking back and seeing prices of those now ($40kish) it was a good deal, I didn’t know enough about these cars to appreciate what I had so sold it before the RB20 blew up. Between here and there, out of 12 cars I’ve owned the note worthy ones are a V8 Lexus SC400 (soarer), a couple of XR6 Turbos and my beloved S15 which I had for about 3 years, picked it up for $12500, repairable write off but she was fine, gun metal grey/pewter and bone stock/unmolested until I got my hands on it. Ended up spending about the value of the car and 280kw, 2 demerit points by the time I got defected and sold it for $14500 (also $40kish in today’s market, rip) Fast forward to the present day, I’m in a much better position financially and daily an MQ Triton (great cars, pipe down Ranger Bois), I cruised marketplace and car sales for a few months looking for another R32, the best deal I could find was an absolute rust bucket half finished project for $12000, until this R33 popped up in Port Macquarie for $18k - unregistered and barely running but decent shape, kept an eye on it for a few weeks and the price steadily dropped, $16k then $15k then $14k, that was the point where I was like shit someone’s gonna snatch this up! It was owned by a young bloke who had big plans but him and his missus just had a baby so smartest move financially for them but big gain for me. So 2 days later I’m towing a car trailer to pick this thing up. Roughly 2 weeks and $3500 later I’m cruising around Newcastle in my beat up R33 all smiles and dose noises! It only needed some basic shit to get it going, coil packs and air flow meter, electrical stuff and all fluids changed, 158k kms and running pretty good, nice smooth engine after oil and coolant flush - when I say coolant I mean it had been filled up with tap water, every gallery and heater element was filled with rust, 8-9 flushes later and still had brown liquid coming out but she’ll be right. The car was painted R34 Bayside Blue at some point but whether it was a cheap job or just not looked after is anyone’s guess, clear coat flaking like sausage roll.  Was rethinking my choices and contemplating life, had it up for sale for $22k - still cheaper than any registered R33 but got little interest, next minute I had an opportunity at work - 6 months overseas for good money, so that was a no brainer, fast forward again and here we are with a 50% finished project. Current Mods - 200ish KW according to butt dyno Was tuned with Apexi PowerFC EBC (old school Greddy Profec)  Stock turbo (more shaft play than a Tinder date gone right) 3inch turbo back Varex muffler  Aftermarket injectors of mystery size, Power FC showed 36% duty cycle at full boost so not behd good size Someone had good intentions but stuck with the stock R33 MAF so we had misfires at 6000rpm due to the MAF hitting 5.2V So far I’ve redone the entire interior with carpet form Car Mats Direct, new Seats and steering wheel from Autotechnica, also sound system by Autobarn (mainly Kicker) Also MCA pro comfort coil overs - Hands down best purchase yet, worlds of improvement over the tired 30yrold shocks Goals - 450kw/600hp on flex tune New paint job - Midnight Purple 2 Engine is at the shop getting rebuilt with forged rods a pistons, new valves and springs, ATI Harmonic balancer, Aeroflow 7.5L sump, rear head drain and oil restrictors as per oil control thread* and cam covers modded for larger breathers, other stuff I can’t recall of the top of my head Parts purchased and to be installed once the engine is done -  Engine loom from Wiring Specialties including these options: Haltech Nexus S3 R35 Coil pack conversion  PRP Dual Trigger kit Fan controller  Other Parts -  262 Kelford Cams Turbo - Hypergear ATR43SS3-ProS with T51R mod (whistly boi) 6 boost manifold (high mount) 50mm Turbosmart Pro gate (plumbed back for legal reasons) HKS Super Turbo Exhaust with High Flow Cat Custom 3.5inch dump and front pipe 1500cc Bosch injectors  Fuel Pump walbro 525 Haltech MAP and IAT sensors Haltech Flex Sensor Fenix Radiator with dual thermo fans LS1 Alternator Kit Oil Filter Relocation from EFI solutions and Cooling pro oil cooler Many other things sitting in my garage waiting for that engine to come back. Progress pics to follow -  
    • Losses have to be less with DC coupling. Provided the battery inverter has decent MPP tracking ability - which really shouldn't be a problem. It's not 2005 any more.
    • Hi, Will the R33 GTR rear brake backing plates fit a GTST? I'm struggling to find GTST ones but can find new GTR ones.   Thanks.
    • I also got the same floor mats for a bit of extra bazzaz haha
    • Some more close up pics now that I’m back to working on the car, the loop pile is nice but again haven’t compared it to the other types in person, it’s hard to tell from the pics on the website. View of the hemming on the edges too, it comes in 2 pieces - front and back, honestly very happy with it for anyone on the fence.  Also attached my previous pics from further up as it didn’t let me post them directly before. (Nothing worse than photo bucket pics that aren’t hosted anymore years later)
