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.

    • Nope.    Grab a varex and turn it down as you get close to home, win win? 
    • So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?
    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks
