Emanage Ultimate

And then a vq35 crank and rods....

Yes the speed cut is gone and the rev limit has changed somehow, it doesnt seem to fuel cut anymore. Not sure if its higher tho, but it would be able to I think.

The ecu runs a standard map until full throttle where it dumps extra fuel. That is hard to get around apparently.

Highflow will definitely get you to 200, more if the piping was changed. Is it worth ripping the turbo out and running an aftermarket? Is there a high power housing that will fit? I dont mind fitting a new manifold, as I would make it myself.

[zei20l]

still wont take you to 3.5L

the bore is narrower on the 2.5 and youll need shorter pistons for the longer rods from the 3.5

[zei20l]

extra fuel at WOT?? weird i thought they needed leaning out

anyway, any chance of a copy of the map?? you dont have to, but it might be a good baseline for our cars when they need tuning......

[scotty nm35]

Alloy bore so no extra size unless the whole short motor fits with the 2.5 heads. You would need better pistons and rods anyway so its only the block.

The standard ecu map is doing the wot fuel dump, its just finding the best way to bypass it.

I will ask if he minds me handing the map out, that should be fine. It should get you very close with no need to spend hours on the dyno.

[zei20l]

sure ask him if its ok! i wouldnt run my car on your map, thats asking for trouble, but yeah it might help lose an hour on the dyno lol

i had a thought, the rev limit is a fuel cut, if the emanage is doing the injector pulsing, then its possible that the rev limiter can be moved...........

All of a sudden 200-210kw's at the wheels is looking very achievable

You doubted it?

new turbo and maybe injectors are a must tho. the turbo runs out of puff too easily....

You know what to do about that...

[zei20l]

hiflow time??? hahah yeah yeah

[scotty nm35]

What power will the highflow allow? The flow is the problem. I would rather spend 2 grand on a HKS aftermarket im thinking, then run 76mm piping right through. Just means making new exhast manifolds and cutting up the dump I just had made.

[zei20l]

do HKS make aftermarket turbo kits for M35s?

No.

They do a GT-RS though which fits.

[zei20l]

i had no idea, might be a better option than a hiflow stocker........ GTRS is a nice turbo!

And then a vq35 crank and rods....

Your on the same track as me!!!!

2nd motor 300awkw's at 15psi with monster torque....should be a cheep rebuild to a 3.5lt too!!....going to get the compression to about 8:1 as well.

[Angus Smart]

thats all it is right? is it a block change? or does the standard block remain and only a vq35 crank and rods used from a 350z??

i'll get that dump back to you soon hopefully, have not forgotten about it

From what my motor builder is saying its the same block with different crank, rods and pistons.

[zei20l]

the bore size is different, so new sleeves too!

[scotty nm35]

Im pretty sure these engines have an alloy bore no sleeve. I think you will need the 3.5 block with aftermarket pistons to drop compression to 7:1 or so.

If the block is taller due to the stroke being longer, it may make the engine bay tight.

Mmm ive definitely caught the bug...

There is of course the GTR's vq3.8dett

Edited July 17, 2009 by scotty nm35

[zei20l]

the GTR motor is a VR38DETT

[scotty nm35]

Ahh, probably too wide to fit anyway. I wonder if they share any parts like cams...

[Angus Smart]

according to that guys web jap blog thing for his stagea.. crank and rods.. from vq35.. but who really knows with the translation..

tho his pistons do look forged..
