Help Required Please

I now have my Lovely M35 AR-X VQ25DET  and I've had fitted my hand controls and wheelchair hoist so I can get around.

Replaced the Nissan Rims with 18X8 rims with Yokohama tyres and TPMS fitted, its great to drive.

Now, what mod should I do first, Brakes , Suspension  or something else?

So if your going to suggest something I would like to know why that brand and the sizes.

Also my M35 is equal to which Skyline model as so far three people have told me 3 different models?

All advice gratefully received if not acted on.

Hi Martin,

Welcome to the M35 scene, Great car to drive isn't it.

 

The NM35 Stagea is not really equivalent to anything, as the VQ25DET engine was only for the Stagea.

No other car ever had it.

The equivalent in terms of date of manufacture is the V35 Skyline which has many interchangeable parts.

The 350Z too.

 

If yours is completely stock, exhaust is usually the first stop.

Once you fit a free flowing dump pipe and 3 inch exhaust, you'll be blown away by the difference :)

Or if you wanna keep it quiet, just do the dump ( Scotty here makes them or you can get Dolphin from Japan )

Best exhaust seems to be the Fujitsubo Legalis R is terms of flow and tone.

Next thing for me was brakes as stock are ridiculous for a car almost 1700kg.

You can get used R34 GT-T slightly modified to fit, or get V35, 350Z Brembos straight bolt on. (Track edition brakes )

I went Brembos wand kept stock master cylinder, feels like a small car to drive now, even towing heavy loads.

You'll need to check your rims fit over though and your spare !!

 

Don't go too hard with your suspension as these are common to tear and crack in the sub-frames and shock mounts.

Remember, heavy car, you can't shovel it like an R32 for long.

 

Nismo S-tune suspension lowers the car 25mm and gives it a sport feel, 20% stiffer than stock.

Not sure if it came for AR-X, otherwise BC's are heaps popular..

An other small mod is the fuel pump.

I noticed better response immediately with the Walbro 255 lph

If you run a constant power source to this pump, the stock 370cc injectors will be good for around 410cc ..( but that's 100% duty cycle ).

You can't use the variable voltage power source for this pump, like the factory set up. Gotta run one off the battery.

Someone here mentioned if you fit a straight through 3 inch exhaust, without any fuel support, you might be running lean as the stock ECU will run out of scope.

Hence possible piston damage- just something to consider.

This was attained from compression testing several cars with aftermarket exhausts..

So in a nutshell-

stage 1 - exhaust and fuel pump, brakes, suspension

stage 2- exhaust, fuel pump, highflow turbo, better BOV , brakes, suspension

stage 3- exhaust, fuel pump, highflow turbo, better BOV, injectors, Piggyback ECU, intercooler, aftermarket intake, brakes, suspension

Have fun..

 

If I was to start from stock again the first mod I would do would be a wideband and boost gauge.

Can highly recommend Innovate Motorsports SCG-1, all in one AFR, boost control/gauge, shift light with logging.

A bit of insurance and you can keep track of what the different mods do.

Next would be getting rid of the "boat like" suspension and bigger front brakes before you start any power mods.

Welcome and enjoy!

Having read all your comments and I thank you all for them.

Yes, I am really enjoying driving again for the first time in 20 years, all my previous cars were just a means of getting from A to B with my wheelchair.

Driving this is such a pleasure it makes my smile just sitting in it. As my carer travels with me and also drives it and I have to keep her safe, safety is the most important thing.

I don't know enough about engines, etc. to put in  Innovate Motorsports SCG-1 what ever that is nor do I know what it does (Sorry datmoo).

So it seems to me that as I'm in a wheelchair and very limited knowledge of mechanic's I should start with something I do understand. 

I'll get the brakes upgraded first then the exhaust,

I'm not sure about lowering the car at present because at its present height I can transfer easily form my wheelchair.

Please don't forget I'm in England so suggesting parts that are only available in Oz and really not helpful but thank you anyway.

or theoretically. 07 350z NON brembo brakes will fit front and rear giving you a 320mm twin piston front and a 308mm single piston rear with the ability to run a 17" space saver spare wheel still 

 

Stripey,

Thank you but I think 295mm Brakes all round will give me a better result as I can get  four piston ones  to fit easily.

My AR-X runs on 18 inch wheels with an 18 inch spare and putting different sized brakes on her seems wrong some how, don't you agree?

iamhe77,

             Could you please explain why as an M35 owner you suggest your choices of a transmission cooler and cooling system mod first?

I can just about understand the transmission cooler but what cooling mods would you suggest?

By the way, I have to have an automatic gearbox due to my disabilities ( nothing works below my waist) so I have ( big toe) brain problems too.

I don't think you'll need any cooling mods unless you plan to track it or launch hard at every set of lights.

And that's if you have a high flow turbo.

I think the stock cooler will do just fine where you are.

A lot of the modified M35s here are in Adelaide and Melbourne, long hot Summers with solid full weeks in the 40's

This is the cooling mod I am referring to and is a necessary item for VQ25det and VQ35de as far as I am concerned. It helps with coolant flow throughout the engine and eliminates the hotspot (and air pocket) created by the blanking plate between the heads. Nissan actually have this line from factory on the VQ40 although it is thermostat controlled.

I always install an external transmission cooler on any car I have because using the 80-95 degree in-radiator coolant to "regulate" the lines from 100+ degrees C in the trans fluid just doesn't seem efficient to me for cooling. Cooler trans fluid temps have been shown to extend the life and lower wear on the transmission components.

It is a pretty extreme setup that cools transmission temps too much (I did manage this with a VQ25det Stagea - two external coolers, no lines to the radiator and outside air temps below 2 degrees C).

conan,

Thanks for the advice regarding mechanics and breakers but as Stagea's are still uncommon in the UK I think breakers are few and far between.

Luckily we have a very good Stagea Club Chairman in Green Machine who can get most parts and if not knows a man who can.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
