All You Every Wanted To Know About Moding A Vq25det(m35)

[andy65b]

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.

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

Andy

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!

I love it.

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!

yeah def a plenum spacer

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

[[[d a n n y]]]

yeah FMIC will be good

probably make it as a whole replacement set up
