I will take that as a compliment, I wish I had a Berk CBE! This is only with the Berk HFCs and the Tanabe Y pipe and the stock muffler but ultimately I will be getting a full CBE to open it up completely.

ohhh..my bad I thought you had the exhaust. I cant read ..duh..

[christian370z]

You have a right to assume, especially because my exhaust is a total of 4 different colors haha. It sounds great though and is so much more punchy than stock. Seat of pants, I probably gained 20rwhp with the HFCs and the Y pipe but I will dyno it eventually (probably at specialtyz).

Next up are lightweight pulleys and a Password JDM carbon radiator cover!

what kinda pully?

[christian370z]

I am thinking about Non Stop Tuning crank and alternator pulleys. I am not sure about the side effects of Stillen's under drive crank pulley without balancing that out with an overdrive pulley. What do you think?

this has been explored in technical detail in some earlier threads... my take is low risk but still not much gain so skip it if you have bigger power goals in mind... otherwise why not... the flip side is there are those that argue the risk is high, but those opinions are based on other engines not ours

Someone here had an issue with the pulley working loose and then damaging the seal and causing an oil leak.

hmmm... wonder if that was an install issue

Could have been, may not have been torqued tight enough. They may have been confusion over the torque specs which are 33 ft/lbs and then a 1/4 turn more. If it were simply tightened to 33 ft/lbs it would fail.

have no issues with the stillen underdrive pully

[christian370z]

So do you guys think it is fine just to get a Stillen underdrive crank pulley or would it be better to get a pair of underdrive crank and overdrive alternator pulleys?

There's no point doing underdrive/overdrive. Either do the lightweight pully which runs at stock speed or the underdrive as is. Just make sure either is installed by someone that knows what they are doing.

[christian370z]

Thanks Chris, exactly what I needed to know. I am having it installed at Stillen since I live a couple miles away, I have to look up the exact Gator belt I need to get as well but I will just go with the Stillen underdrive lightweight crank pulley now.

I appreciate the help!

I am going to add the aero package front chin spoiler shortly but wanted to balance it out with something extra on the rear of the car. I do not really like the sport package rear wing in all honesty but the rear looks a bit plain as is. I also don't want to upset the aerodynamic balance either so I was thinking about getting a Stillen roof spoiler:



What does everyone think? If it looks as low key and fits like the picture, I think it would look great.

Here is a video of what the car sounds like with my current mods. I am guessing from the seat of my pants that I should be fairly close to 300whp but most importantly the car feels and sounds so much more raw now. Sorry I couldn't get on it more, I just wanted to get all the major driving categories in from WOT to mid range part throttle to cruising. (windows are closed, camera mic gets fuzzy with wind)
