But I was wondering which would be better for a stockish type of engine

I know what sort of twin setup I would go for was thinking like twin Disco's as I hear the responce on these are great and they will support good top end.

But if I was to go a single which would give me sorta the same result.

I am happy with the stock twins but I would like to invest in a good turbo setup now which means I won't need to worry later on if I choose to go all out on the engine.....

I'm going to race the car and I would like to get as much responce out of it but still have the high end power.

Just wondering

thanks

the single turbo counterpart to the power the 2860-9 turbos will give is the 3076R. however if you go that route you have to buy all new manifold, dump/front pipe/intake pipe, intercooler piping etc. cost wise you are better off getting a set of twins.

twin disco's is a no go. there are bolt on replacements.

as everyone is suggesting, get a pair of -9s and get them installed. they are a good upgrade over stock and will make an easy 300kw.

Buy the turbos now that will suit you in the future.

There's no point buying something that suits the motor now if you're going to change the motor later IMO

Also, make sure someone who knows what they're doing does the work for you. I can think of a few Sydney GTR's that have -7's and one with GTSS's that just don't seem "right". But then i can think of a few Melbourne GTR's that have the same turbos and they go like they're made by NASA.

I wish someone would make something bigger than a GTRS in lowmount form :wub:

Its probably just my personal opinion, but if you're going to build a GTR, make it a fast one! I cant understand why people do the whole built motor thing and a catalogue of parts thrown at their car to finish with 300awkw for example. A stock one will do that! Spend the money on tires, brake discs and pads then go track it until you're sick of it, that will work out much better for your wallet

EDIT: Unless of course you kill the motor, then you're no worse off than when you started but you've had fun along the way

See I'm the other side of the coin - IMO buy the turbos to suit the application now, and then just change them later.

You can just sell them off 2nd hand anyway, or keep them incase you don't like the feel of the larger ones. You'll cost yourself what, maybe 1k... in the overall scheme of things that ain't particularly much.

Nothing wrong with putting a built motor in for 300rwkw either. R32 motors especially are long in the legs and R33's are getting there now as well.

My motor could hold 400rwkw, but I only ever intend to make around 330-340rwkw out of it. I did buy it blown, so i did have to rebuild :wub:

More for reliabilty's sake as opposed to anything else was the reasoning hence i didn't go with a running stock motor as i CBF'd pulling a stocker motor out later when it died - just build, insert, happy times.

Well, it was just personal opinion then :wub:

You make some good points aswel, i definatly agree buying a blown motor and building it up is better than rebuilding whats in the car currently.

It means the owner can take their time, get the parts they want, and the car isnt stuck in a workshop covered with dust

2860-9's for a stock 26 would be the way to go.

-5's if you defiantly want to build the motor (soon)

I wouldn't mess about trying single turbo setups unless you go for a twin scroll manifold etc.

hey, sorry im just learning about turbos, but would you go with the -9s to start with cos the A/R ratio is higher, giving more power? but the -5's A/R is lower in peak power so not-advised unless other most are coming too to raise the power?

or have i got this all wrong?

The trust T618Z 10cm kit seems to squeeze a little more power than the GTRS's... There is also rumors of a T620Z kit on it's way. Should be intersting.

You'd be mad to choose a top mount set up for anything less than 400awkw.

Didn't know anything about a new trust turbo coming out, thanks for that!

I wouldn't be betting on it though as the jap companies are all so focussed on r35's now

still, I'd love to see it happen!

      I sense an out of control build thread coming up lololol. That 450kW goal will end up being 600 to 700kW LOL.

      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

      RB25DET Neo Rebuild

      By pacman_1219 · Posted

      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.
