M370 or some pulleys?

Appreciate the input, Cant decide on next mod - whats your take

Fancy either an M370 or an underdrive pulley with matching belt etc.

Current mods. (sticking with stock cats for current project) ART pipes again later.

I am curious to do pulleys myself, I might do that when I have some extra money I can put towards the car but with your mods, I don't know if the M370 will show any large gains as you have completed the breathing mods.

I'm a little worried about the posts about improper pulley installation damaging the engine.

The IM will move peak torque lower... be interesting to see what you can get out of it with a tune.

Probably break even up top, but potential for a sh!tload more torque down low. How's your traction now?

both man, but pulley for now and get M370 when your ready for tune

iam running a stillen lightwheight crank pulley,installed it myself,never dynoed before and after but it did seem to allow engine to rev up thru the bottom end a bit quicker,its a good value to

I think it's a good value if you can install it yourself.

I didn't, and am glad I did not attempt it. Took the garage two hours to install my set (not Stillen) and I was watching them the whole time so I know they were working on it.

Thing was hard to get off, then had to sand the new crank pulley to get it to fit.

Seems nice now but at $190 + $140 installation...well...that's not a big bang for your buck by any means.

I can't tell much difference really performance wise, but we are only talking 5-10 hp here. It did seem to smooth things up a bit though.

Would imagine it has to rev a tick faster (those are some heavy pulleys that came off).

I say go for it... it worth the money, but buy their belt too because the stock belt will be kind off lose with NST kit.

Kastley85891 · 03-19-2011, 12:57 PM

Thx - worth knowing - best go shopping for a puller

I went with the NST pulley kit & Belt and I felt a definite improvement over the stock pulley. The car feels smoother, slightly quicker and switching from 3rd gear onward, the car feels faster. I also had gas mileage slightly improve but then again it could be from the new filters I installed along with the pulleys. No issue during pulleys install.

I've been dealing with a Nissan Master Tech and he stated that the M370 would likely reduce HPs but increase torque, the loss of HP can be easily regained through tuning. I plan on doing this once done with other upcoming mods

Kastley85891 · 03-19-2011, 01:09 PM

Any recommends on 'good' deals on the NST kit with belt etc?

Appreciate all the input
