Hey lads.. Im really thinking hard about getting a new Turbo for my R34 GT-T, their seems to be so many to choose.

But i dont know what would suit an R34 the best.

I dont plan to run stupid amounts of Boost, id like to go a maximum of 1bar tops and maybe short bursts of 1.1bar.

Ive been trying to find HPI mags with articles on R34 GT-T's, but to no avail.

I dont want to get anything thats huge either, as to reduce Turbo lagg. So what would you guys recommend I look at?

cheers.

Gaz

have a flick through Rb25 Turbo Upgrade, All Dyno Results might give u a better idea different results people are getting with different turbos.

i run a garret t3076r which is a lowmount with internal wastegate.

i find it to be pretty responsive however other bits n pieces will need upgrading to make the most of it. (am aiming at 1.4 bar)

if you only plan to run 1bar however you may get away without some of that.

i'd have a chat to some workshops and get their opinions then do some research based from their recomendations.

ultimately the more honest you are with what u want from it in the first place the less dissapointed you will be in the long run.

good luck with it.

Yeah, search around, I'm sure there was someone asking this exact question about 1 week ago, almost identical title.

Anyway, check the Dyno thread like already suggested and remember R33 turbo upgrades = R34 turbo upgrades.

Same same.....

Cheap options are 2nd hand following :

HKS2530 : make 1 bar fine - Robo's has a thread showing around 230rwkws and loved it (at the tme)

HKS2535 : Probably more suited to RB25 as better top end, only slightly more lag.

GCG highflow, i would say close to HKS2535, not sure which is better but so close it prolly doesn't matter.

Cheap new :

Slide highflow, heaps of peeps have em.

Pricey new:

HKS GT-RS - i won't one !! but $2300-400(?) for new but that's the whole kit delivered from Japan.

great for 240-290 rwkws i believe and super quick spoonin'

GCG highflow new, around $1750 exchange i think in the group buy section?

Good luck.

Go get yourself a Hi mount manifold with external wastegate fitment, 250~,

get an external wastegate ~300-600 depending on what you buy,

get a Garrett GT3076R from slides or soemwhere cheap, ~1800 or so,

get a computer after that, with bigger injectors and a bigger AFM,

then be happy with ur brand new car pretty much.

If you want stealth mode,

get a GT30R hybrid with IW, 1,800-2000 or so,

keep you stock low mount manifold,

get a cheap but good manual boost controller,

set it to 9-10psi and keep it there until you find money for other stuff.

No offence Pauly, but seriously, was that your 1st turbo upgrade?

I just did my own HKS direct fit job which would have been marginally harder than a GCG highflow direct swap out and man, what a headache. But only cause i couldn't source 1 particular $6 part! Held me off for over a week ! Haha. And mainly cause Pirtek didn't know thier own parts! Had a pic of it too and they still didn't know what it was. Thing it, it was a pic of a pirtek part ! Sheeet...

Although the next time around it will be heaps easier as it won't be so 'new' to me.

Yes it was.

I blew my turbo after an exhaust install which I accuse of foul play, then I decided... hmm... get a stock one, or do what I was gonna do in 6 months anyway. So I bought a GT30R turbo and havent looked back, now I need new injectors, afm and ECU, and most probably splitfires.

Theres nothing unnessesary about that for my target power of 250kw.

BTW, I just paid 700 dollars for a metal cat with 700CFM of flow and a customised dump pipe with a screamer attachment, and I wasnt gettin my money back, so I had ATS make me a kit that utilized the GT3076R compressor wheel in the RB25 housing (after being max hiflowed), and its been excelent so far.

The GT30's are great turbos and are, I think, a great replacement for those looking to see ~ the 260kw mark after they have finished engine modifications

Freegan hell! Good work dude .

Sounds like you know what you are doing

...i don't, haha but I'm getting there.

Aiming for 250 aswell but that will be the limit of the hks2535, I think the GT30's can push way more can't they? As in 300rwkws?

yes gt3040 can push well over 300.....thats my pick. But you have to know what sort of power goal you have in mind. Like are you after 230, 250, 280, 300, 350 etc there are also other mods such as cams etc etc, what mods do you have atm. its not always about how much boost you want to run its more how much power you want to make, and with your driving style whether you want ultra response or dont mind a touch of lag for that awesome rush of the bigger turbo. Also what sort of budget are you on, you have to think new turbo means in most cases new inj, new afm and in most cases a new dump pipe and a tune.

    • Nice, thanks for sharing your progress....that's a pretty long list you are putting into it!
    • Decided to upgrade my pressurised plastic coolant expansion tank for a fancy pants alloy version The OEM versions can get brittle, even the new plastic one I got when I first got the car is a starting to show signs of "stress" I wasn't cheap, but it is basically unbreakable
    • Morning all, I have an RB25DET Neo that's in need of a rebuild. Will need new pistons etc due to detonation damage. Would anyone be able to recommend a shop in Southeast Queensland who I could bring my long motor to for a rebuild? Just want someone who knows RBs and whos built a bunch of them before. TLDR - recommended engine shops for RB rebuild.
    • 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.
