Of I am unhappy with spool up time I'll get them gutted and ceramic coated and we can compare

:tup:

Looking at the graph on the nismo that STS posted spool up time should be fine but every car is different

Spool up time would be the least of my concerns if the car was mine. I only mentioned it because you were told that by keeping the cats the turbos will spool faster. This is not true.

I would be worried about the cat failing and then picking the turbo in pieces.

yeah i agree, spending that much on a turbo just to have it destroyed by some debris would break my heart!

I know that would suck, I don't want test pipes and I don't think hfc would solve the problem, it's not a big concern for me and even the r and d department at STS tells me it's fine but damn u guys are making me nervous, I just don't know what route to take

I mean it will be fine for a while, its not like the whole thing is gonna blow up as soon as you start it. I would run test pipes, add resonators and call it a day.

But dont test pipes stink :(

Gas smell. Not to bad IMO.

It's not as bad as you think man, there are plenty of turbo cars out there without cats.

First off the install looks great so far! Hopefully that thing will be on the street next week.

As far as the whole "CAT issue" I basically said that the stock cats would be just fine as long as the tuning was close. There is no spool up benefit by keeping the stock cats. Sorry if there was some confusion there....

The increased heat alone is NOT going to destroy the cats. It will however make them more susceptible to failure but they can sustain far more heat than you might think. We know this from the past 10 years or so of turbocharging cars with stock cats. As I stated above, the factory cats will be fine up to a certain HP level and as long as the tuning is close.

Even if a CAT "fails" it's usually the first section of the cat that lets loose and gets clogged up in the second section. You WILL know that something is wrong since your car will feel like there is a potato stuck in the tailpipe. If anything does comes out of the tailpipe it is usually just a very fine metallic dust, usually nothing that could bend or break the exhaust wheel.

I ran well over 500whp with stock cats on my personal vehicle for years. When I swapped in a set of high flow CATS the stock ones looked just fine. The only reason I even swapped in the HFC’s in the first place was because they were given to me, NOT because the stock cats failed.

There are reasons to change or remove the CATS altogether. However, on a stock car making 500+rwhp the stock CATS are usually just fine…..

I'm just waiting for the ECU part number from the shop doing the install then I should be able to get a tune over later today!

Thanks for clarifying !

Ahhh the customer service in action.:tup:

Nice build!car looks great, your gonna love it can't wait to see your numbers.:tup:

Nice build man!

The sts kit is looking very appealing to me more and more...

Really looking forward to seeing numbers on this kit!

Gotta say watch for exhaust leaks....it killed my car on the dyno today....I'm talking almost 100hp kill...:mad:

Where it leaking from?

first pipe (intake into the turbo under the car) first splice after the catalytic converter. So I would make sure it put on correctly.

Well fix that ****!

:icon18: Working on that one. I'm hoping to have it fixed shortly. Then take to real tuner and square everything up.

Mine should be done Tommorrow or tuesday no fittings came with my gauges or enough vacuum line to get to the turbo and back so their taking a while

It seems to be going faster than my build...time bought to finish was almost 6 months. Just hope you have better luck than what I'm having. You have to cause I doubt your installers are "special" like the ones who installed mine.

Lol it'll be like a month for me but they've only been workin in it for a week

See that's about the right amount of time...:facepalm: only if my installer would of taken notes on how to do an install

I don't know about keeping the stock cats bro. Besides the fact that they are extremely restrictive and a set of test pipes doesn't cost much more especially when you've already invested so much. I remember seeing one vid on here of a member who had bad cats and trust me there was more than just "dust" coming out of the rear pipes. I personally would be terrified, one small to medium chunk of the cat filler will erase all your hard work and cost you a new turbo.

Money ain't the issue at all it's just the sound and smell you get from test pipes

And the turbo is the most restrictive part of the exhaust

I currently have long tube headers, before that I had GTM unresonated test pipes. The fumes aren't that bad, I only caught a whiff upon startup and when sitting at long lights.

I was gonna get lth but just left it stock , the car is off the lift and the install is pretty much done maybe later when I get my boost controller I'll switch em out but probly not tbh I trust STS over anyone else with this. They've done thousands of vehicles and theres like what a handful of vehicles that this happened to ? I'm more worried about the problems people have been having with the tranny

The m6 transmissions have held up under boost better than the 7at. You might want to look into and aftermarket clutch and csc but that modification is a lot less than the four grand the 7at guys will have to throw down for a built transmission.

Curious how this turns out. Pictures I've seen of the STS looks like the turbo could hit speed bumps and the like, but maybe it's just the angle of the pics?

Yes the clutch is the next thing to buy

The turbo is actually quite high the pipe that's low is the exhaust pipe comin down from the turbo and is say its about 1/2 inch higher then stock exhaust

Sub'd. Build looks great and I'm really wanting to see the results. I may purchase this kit in the future.

You have to some how high center your car on the rear end to even touch the turbo....you really have to try to hit the turbo:tiphat:

Numbers today boys! Also what's the easiest way to drain the gas tank I got older gas in it so I don't really wanna tune on that

Circle Drive at 160km/h...... :driving::rofl2:

Haha where abouts you from?

disconnect the fuel line in the engine compartment and hook it up to a hose to a gas can. Then power the fuel pump with a power probe and it will pump it out at about 255l/hr....lol
