Spent an hour with a stillen rep on the phone...
He's getting together customer dyno charts and will have them for me by tonight. He was a very nice guy to be honest, but don't you have to be if you want to sell thousands of $ worth of stuff? lol.
Anyways,
I'm making him work his *** off to convince me to spend money with them, so hopefully now we can finally see some stage 3/4 dynos. I told him I wouldn't touch stillen without proof considering their forum reputation and how much criticism and negative feedback there is for them. I'll be posting them of course
"There is no way that we can get out of a stage 2 warranty" he says. I said bs, he said its true. hmmm
Also, there is no way for them to get the 2006 300hp engines past their stage "3" (stage 4 actually is what 3 is). They said that power is maxed out and any more would put the engine at risk. He did say I could "get any kit I wanted" as long as I sign a waiver, I said "haha, yeah right. I want written proof that my warranty will be covered."

Who needs warranty? While you were on the phone with them you shoulda asked them why they are using a 4banger blower for 350z kits and persuade them to make a kit that actually puts out some power.
I'm just doing a public service and getting concrete information about stillen...
for once. And this is Ronin's explanation for the size of the blower:
The following is from 350-tech

This is factually inaccurate. Yes the Stillen kit uses the Eaton M62 blower. No argument there. However the Honda Prelude kit was the Eaton M45, a 45 cubic inch blower. Vendors who integrate Eaton superchargers into their kits have almost no say over the size. Due to the effeciency rating of a roots type blower, they rate different size pumps for different displacements of engines. Eaton calls for the M62 to be used on 3.0L to 4.0L engines. While the M45 is for 2.0-3.0L engines.
Stillen could have used the M90 which is good up to 5.0 liters, but the hood clearance issues would have been even more exaggerated. Plus the stock internals really wouldn't be up for that sort of abuse. Since Stillen's goals seemed to have been ease of install, CARB approval, and relatively low maintenance... it would seem that the choices were very limited.

I dont care if it puts out less WHP or not. The kit is good for what it is supposed to be. It is designed to be a safe kit for your motor and that is what it is. All the people with Vortec and Greddy are blowing motors left and right and very seldom do you hear of people blowing motors with stillen. I will be adding one in the near future and dont plan on racing at the track or strip so it will do fine. If you bought your Z to track then you have way more money then I do, this is my only car and I cant afford to replace the motor at any given moment. That is what stillen has set out to help with and accomplished.

Perhaps, but I want to finally lay it to rest (for myself) by seeing just how far the sales rep tries to go in proving that it's a quality product. the phone convo was entertaining because i kept throwing forum stuff at him

Absolutely. Since I'm in the FI market nothing has been more frustrating than seeing assumptions and second hand data about things that cost thousands if not tens of thousands of dollars.
Frustrating. I want answers!

I bet there are more blown stillen than vortech.

Of course no FI is engine safe.... hence the word "forced."

I bet there are more blown stillen than vortech.There are also more users with more milage on a stillen forced car then vortec, at least with a stock bottom end. I agree that if you can build a block and pay for hours of tuning then stillen is not the way to go, but if you just want to spend 6k or so and be done then stillen is your best option. For the amount of money to build a block and buy a TT kit and pay for tuning you could have just bought a used viper or vet Z06 and would have been better off. Dropping 13-15k on a 30k car is not financialy smart, you will never regain even half of that money.

otherwise it can be viewed as a long-term investment in fun
if someone didn't think the stock car or simple cheap bolts ons were fast enough for them and they're worried about being financially smart, they should have bought a vette or GTO or whatever and then later sell that when the next big thing comes out. Financially it's stupid to trade up every few years anyway

And wouldn't that be the goal of the stillen kit? ;x
