Xcceleration Performance Stage 2 kit
Has any purchased this kit for the STi or seen it in use on an STi? If so , did it seem to be good output for the price of roughly $3000.00 depending on the use of the cats. The stage 2 kit is claimed 430hp - 340 w.h.p./ 455ft/lb. Is it reliable or does it seem to be a quality kit.Thinking of adding it on my STi and need to know if I'm wasting my money.If there is a better kit out there.....who makes it and costs?

My bud has this kit. It is great! The car is soooo fast. Beat a ZO6 fast! He has the kit with the cats. And always gives xcceleration two thumbs up. He has had NO prob. at all with the car. No better kit unless you want to change the turbo. If you change the turbo it will be big $$$. It has been on the car for 3 months and he drives hard.

I suggest take each individual part they offer and find a similar product and compare pricing. The have an advantage of the catted exaust but remember those horspower numbers can not be at all real. Numbers like that will net you in the mid 11 sec 1/4 mile! With that said, the stock turbo is maxing out very easy and overspins with only a catback and intake, not to mention bad boost creep at part throttle to 3/4th throttle. Not good, creating very lean conditions! The fuel injectors are in stock trim also near maxed out so you can only imagine that It would be very difficult to net those actual #s. Maybe 320+ at best. Check around and do your reserch. They do have Quality exaust but well I just think you need to make sure you know what you are in for.

If you do a search on Nasioc.com I believe this kit has been completely denounced. The actual numbers were much lower than poster on their site. I would look for the info on Nasioc before you spend that much money and quite possibly end up very dissapointed.

DENOUNCED! You are nuts. Do you live anywhere near new york? We will take you for a ride and show your crazy a$$. The two of you don't even have the kit and talking $hit. You two need to be Denounced. For having NO CLUE! Plus we have not taken car to the track yet but if its out beating up ZO6's it must be in the 11's some were. Talk when you know what you are talking about. None of what WEST said is true.

I don't care who you are, you can't make that much power on a stock VF39. Period. It's too small.
Here's i-Clubs version of those Nasioc threads (the last post links to over there). Xcelleration.com is selling snake oil.

Sorry If I offended anyone but sure, do the math is right. I just am suggesting since most people are seeing boost taper at higher rpm's in the STI with the stock turbo plus the numerus posts of injectors already nearly maxed out etc.....
stock is what 250+ or _ Turbo back+20hp without cats CIA+5hp and tuning to max efficiency of the turbo (truely 18.5psi then tapers at high rpm if your wast gate works right) ====70 to 100hp all gains at the wheels so you get what over 500hp at the motor on stock turbo? Sorry just try it your self, I only cary an estomated opinion from what I have learned from research.

You said it yourself- never dynoed the car, never taken it to the track. What basis do you have for claiming it makes 435 hp? I've watched a lot of cars with LARGER turbos get dyno tuned, and they don't make 435 at the crank. You and your friends are full of crap on this power claim.

Let's see a scanned time slip. I'd like to see a trap speed to verify the power of this kit.
Xcceleration.com kits for the WRX and STi. All of their WRX and STi kits use a piggyback Unichip - welcome to 2002 technology. They also use a manual boost controller. Nice setup for that occasional full-boost at part-throttle condition that can lead to excessively high exhaust gas temperatures.

S2000, I don't have the kit but from all of the research i have done, everyone (except your buddy) has said that they didnt get the advertised results. Granted the STi ECU is real quirky and every single car seems to be different, this kit still has been denounced by the Nasioc crowd and there are some supremely knowledgeable people over there.
The best thing to do would be to get your buddy to bring his STi to the EVO vs. STi shootout on 9/11 at E-Town. I will be there with some friends with my STi (hopefully have EcuTek by then) and some other STis and WRXs. I am interested to see how well the Xcceleration kit does on the track, and I wouldn't mind it at all if you proved me wrong.

BAN SUVS, Anyway, I have a Supercharged S2000 It dynoed 300.3 h.p. at the rear wheels which is 348.3 h.p. at the crank. He runs on me like I am in a VW BUG. I run on C5 vetts like they are running on 4cyl. You are not talking to a bunch of kids. You sound like a punk kid,who wished he had the money to buy this kit.
Not one time in this thread have I said it has 435 h.p. I said it is fast.
