Looking at a Precision turbo for my rb25det Neo.

From what I've gathered the 6266 0.84 should match nicely. Motor is internally stock but will be running E85.

I'm thinking about spending the extra cash on a twin scroll setup, going to be in a light S15 so I'd want power delivery as smooth as possible.

Any graphs or comments for a similar setup

Hey dave do you have any specs on whats done to the head? Im guessing its got some $$$'s spent on it? As good as the 6466 is dave I would still keep the good old HKS T51R. :) TILL THIS DAY, They still sound the best out of every turbo out there when spooling and cracking that big gate open. Not to mention how farking PORRRRN they look in a skyline engine bay. Haha. How much more do you reckon the t51r has left in it on your setup dave?

At this stage piggaz has talked me into going a pt6262 on my built rb25 with a r33 gtr 2.6ltr crank in it. After seeing all these 6466 30/25 or 30/26 setups making such grouse power makes me just want to build a 30 bottem end and go 6466.

Why would you wanna change it when it sounds like this :D

Took a snap of the graph from the 6466 on the RB26 that JEM tuned the other month.

Soooo much midrange for the power output.

+1 on getting specs of this motor. 950 ftlbs and 30psi at 4700rpm from a 64mm turbo on 2.6L? how is that even possible?

I'm pretty sure it's just a basic build.

Forged pistons and rods, drop in cams etc.

TS 6466.

We went out on a cruise sat night with a few other big HP GTRs and this thing annihilated everything, every bit as responsive as the graph suggests.

Loving the sound of this

Richard had to drop the motor as it was sitting too high and the plazmaman was hitting the bonnet, I was there on Thursday dropping off some E85 and Richard said that it was due back from the exhuaust shop later that day then they had to drop the engine and finish off some of the connectors and a few hoses here and there and then it will be ready to start and hopfully tune. He said should be ready by mid this week

God. I can hear the money burning by the hour.

I hope it turns out well for you mate :thumbsup:

Not the same on the street?

How much more than the 6262?

With the hubber they are usually about 300-500rpm better on the street. With the roller it's usually closer but even if it was the same as the dyno it would still be awesome

We'll, forgive me for being a sceptic, but I need to see a timeslip or data log to believe. This thing still makes 200 ftlbs more than I thought possible and spools earlier than a 35r. Crazy!

When I had a GT35R it was on song (26psi) by 4400rpm. This thing is laggier than that, id say T04Z territory.

These aren't a big turbo physically which is surprising to see what they produce. Looks like a GT35R from the front but the rear housing looks quite large.

The blade design on the turbine side is also something I haven't seen before, it is like the blades are convex. (if that makes sense)?

Just to add, I have seen 2x SR20VEs with these turbos making more power and on earlier than my T51R KAI RB30/25.

One ran 154mph and the other 148mph, both 5 speed H pattern cars.

    • 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.
