I have had time to go searching the net tonight looking for info on the VQ25DET.

I have come across a site about some one who has done every possible mod to the M35 inside, outside and to the motor.

Not only has he improved the turbo and the manifold but he has taken it out to a 3.5L VQ25DET.

http://translate.google.com.au/translate?h...N%26start%3D150

Have a good look over the whole site and look for items to click on as there is all sorts of information in the background.

It looks like it is a company called TEPS that does most of the mods and using a Fcon computer.

This is soooooo interesting.

Cheers

Yeah, this was first posted in the "M35 info" a little while back (nice to be able to find it in its own thread though :( )

I am currently trying to get the intake available for everyone, but this may take some time.

The turbo is a GT-RS. Similar to Craigs(?)

Done some nice stuff to it, although everything that is not a "TEPS" item is pretty much a bolt on aftermarket item.

There was another one that installed a VQ35DET and was pushing 450awPS.

Did you see the part where he installed a 20mm spacer at the top of the cylinders to increase the capacity to 3.5L.

Very tempting.

Nope. Didn't read the whole site. I am more of a picture looker :(

Love the idea though!

Didn't TEPS use VQ35 cylinders and cams or something?

I certainly do like his plenum!

You can click on a lot of the photo's and go to more specific information.

This is the section where he fits the 20mm spacer to the block. From what I can work out he does not change any of the internals at this stage.

Thanks for the link to the page, Andy.

Haven't seen that page before.

That is what we are looking at doing when I was referring to a plenum spacer. But we were looking at 10mm. May have to change that size.

From what I read it was a prototype and he seemed happy but in the end does get a full rebuild using 35 pistons and cranks etc chasing more power.

It is additive.

I was just reading about the replacing the intake before the throttle body and he talks about more consistency in boost and better throttle response. hmmm. so much to do and so little budget.

Are you referring to the cone shaped piping between the 60mm rubber intercooler piping and the trottle body?

Scotty was kind enough to modify a 300x76mm piece of aluminium piping to use as a replacement (incorporated BOV mount).

Just need the larger FMIC and make up the rest of the piping.

So much on so little? Tell me about it!

Frustrated to Hell! :(

Yes, The cone. I will wait for the HDI unit I think and see what it looks like.

      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.
