Get rid of existing and get braided from the turbo to the block. Personally I would get something custom made from somewhere like Enzed (well actually I make my own lines using Speedflow gear, but I assume you're not game to try that?). But plenty of people on here seem to be using the Kando lines with no problems.

The 6262 sillyness is never ending... New cams just got the most power and torque it's ever made

Dale is 100% correct its a well proven fact that smaller cams in RB's aid in response. Even going from a stock cam to a type b pon cam will cost you response. Been many track guys that have thrown the

FYI both 6262 and 6266 are rated as 700HP items. I'd be chasing that 66 CEA item, better tech is where its at.

The 6262 is 700hp and 6266 is 735hp.

Don't be fooled by the CEA crap, the wheel sizes have an influence over response, and the 6262 is more responsive.

It might be that the 62mm wheel is more responsive, but by how much? You can see that the CEA wheel has better blade design and would be an overall lighter rotating assembly. Im also confident the 66mm wheel would flow a metric shit load more.

If you were going 3L down the track I can see that the 66 mil would make for an intensely fast car.. but yeah I can accept 4mm in turbine exducer isn't anything to scoff at.

Thanks hanaldo, I will look at the lines a bit, sorry for the spam on the Precision thread but did you end up re-tuning your G3 again/ killawasps?

On my car I have had a 6265, 6765,6766 and 7175. I have witnessed a 150rpm difference between a 6262 and 6265, hardly noticable, but there was also a couple of hundred revs between the 65 and 66 turbine wheels on my own car.

Yes it picked up 30hp atw but the point I was trying to make was, PTE marketed the same if not better response between the CEA wheel replacement wheels of the 65. Maybe that is the case with identical sized wheels, but from my experience not a bigger CEA vs smaller wheel. You can physically see the difference in the thickness of the older wheels.

It's funny that a 3 mm larger wheel with a 62 mm front was only 150 but 1 extra mm on a 67 was alot more noticable. Hmm.

got to remember that its 1mm on the exducer but they dont tell us what they have changed on the inducer. Could be a way larger wheel in a smaller trim... or could be a smaller wheel in a larger trim. Who knows..

PJ did you ever dismantle yours to measure the inducer on the turbine side? I have always wondered why PT dont farking advertise those figures. With the smaller stuff I had a feeling they kept it to themselves because the numbers would match up to older tech T3/T4 based things. Bad for business when your marketing 'new tech'. Obviously we know overall measurements are not the be all and end all, but it would certainly raise the question.

Yes we did, and you could be onto something there :whistling: either way they worked and worked well!

It would be interesting to back to back a CEA of the same size, but after spending 10 grand of my own money on Precision turbo's, I might leave it for one of you boys to step up :)

      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

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
