M35 250t Buying

[andy65b]

Yeah sorry my bad. The series 1 & 2 stageas run at 7-8psi (i used to own a s2). You're quite correct - the M35 is about 0.8 bar.

1bar is definitely too high for these turbos...given the number of posts on here about the stock ceramic turbo (skylines, earlier stageas) disintegrating around 14psi. I'm assuming the turbos, if not the same, are very similar to that of the earlier stageas?

The M35 turbo is quite unique. IE. nothing like it at all.

It is a ceramic turbine but ball bearings on the shaft.

It seems that most of the turbo problems have happened after our very hot summer. There seems to be merit in the larger intercooler. I am told that the turbo is in such a tight space and close to the engine that heat tends to be it's undoing.

It is not described as the most efficient turbo but it does suite the purpose on this engine quite well.

Cheers

I'll just add another question to the thread .

I've seen a few photos of custom/aftermarket exhaust system for the M35 and are wondering what the extra pipe/cylinder is on the main pipe is just before the main pipe ducts back over to the muffler. I gather it's some type of noise damper? I've also seen an extra bit of pipe in one of the front downpipe photos as well?

Photos I'm talking about are here: http://www.skylinesaustralia.com/forums/St...amp;hl=axis+m35

Cheers.

Yep, it is a resonator to help keep the Fujitsubo Legalis under JASMA sound limits.

The "extra" pipe is on the dump and is a pretty standard way of doing them, don't ask me why, I don't know.

I would have thought that a bellmouth design would have been more efficient.

Cheers for the reply.

So going the custom exhaust I would need to fit a couple more resonators and a good muffler to keep the noise down when not having the Fujitsubo Legalis design?

Not necessarily. The Kakimoto exhaust (forgot the name) uses a mid muffler (not large) instead of the resonator to keep it quiet.

When I say quiet, I mean ~88db with the stock dump & front pipe.

If you happen to put a de-cat front pipe on (like I have - there is still a cat on the OE dump), the volume will increase but you get a lovely deep burble. Luckily for me the Fujitsubo still keeps it under control.

Just in case you did not read it in another thread, my exhaust consists of the stock dump, Kakimoto front pipe and Fujitsubo exhaust.

Great setup, high flow, great sound, but will set you back quite a bit with the current exchange rate.

What was the improvement like, better response, petrol bill?

I have a good friend who can build me a nice custom setup, does a lot of work on the Skyline as he owns one himself. He should be able to sort a good setup for the Stagea.

Thanks.

Response was the same up until 3500rpm, although I was able to have a lighter foot when going uphill.

Boost increases from 0.8bar to >1bar at 3600rpm and pulls strong all the way to redline.

Petrol bill is about the same.

Went from 9.3km/L to 9.1km/L on my old route to work... but that may be because I just wanted to open it up more often

Economy now sits at 8.3km/L with only short burst driving (lots of lights & round abouts).

On the whole, wouldn't change a thing.

The engine spins alot more freely, power is made with less effort (particularly torque) and it sounds ace.

Only thing I would change if I could, would be a free-er flowing dump (with cat).

Picked up my Stagea a couple of days ago and drove it back home for a good 450km's.

Quick impression:

These things eat motorways no problem .

Low down grunt makes it so easy to drive.

Handling is pretty good for a large wagon, bit of roll at the start then stays flat.

Plenty of room inside.

The model I have is the 250T RS Four with leather interior.

Few marks on the front and rear bumper and interior that will need sorting but in pretty good order.

Things planned are towbar, full 3" exhaust and open up the airbox. Will post some photos later.

Will be posting up a few more question about bits (after I've done a search )
