The customer wanted a T400 because of cost and reliability. It should cruise fine on the hwy with 3.08 gears.

As far as clearancing, the head of the passenger side motor mount bolt had to be ground flush, and a small section of the top of the motor mount bracket had to be clearanced. The GT35R's fit much better. As to which turbos are better, the GT35R's have a 61mm compressor wheel and the PT67's have a 67mm compressor wheel. The 67's should be capable of a bit more power but I won't know until we run a similar combination with the GT35R's.

The turbo system will absolutely not work with the stock K-member.




Looking awsome guys.....

Yeh, Jim actually is the designer of this awesome kit, which i just spoke to Frasier on the line about, wink wink. I am currently seeking the ball bearing setup, which rates around 9200, not bad considering i already got my BS3 from the Mrs. for Christmas!!! Awesome Kit, i wish i had more footage to see..

if you spent 20k-30k and resulted with 625rwhp would you feel cheated?

now dont get confused im speaking in a general sense, not trying to knock speed inc or their products because they do a hell of a job, but that set up should yield a whole lot more than 625 on 93 oct.

As stated, I believe good gas is cheap insurance. Their is nothing about this combination that would allow you to push it -less- than any other on pump gas.

The only way to find the true limit is to push it on 93 until it breaks. If you want to donate your engine for testing I'll be happy to find out that limit, but generally our customers would prefer us to stay conservative when pushing nearly 1000 crank horsepower with their brand new combination.

hell, id love to donate my motor i bet t60's on my stock block would be fun as hell, unfortuantely for the time being ive got a stock everyting block haha. ive got the "college cam" just a bottle in the back. once i graduate ill have lots of free time and money. i do admire you guy's work, but all the gas i can get around here is 93, and i drive my car way too much to get anything better. i did forget to take into consideration that the combo had a th400, and no i have no real world experience with ls1's and turbos, but i hope to change that in a couple years

Jim, do you tune the cars with a dual spark map? The way I have mine setup is to pull 4 degrees of timing accros the board if the computer senses low octane fuel. That way I can have my cake and eat it too! basically it is a fail safe incase the pump it putting out something lower then 93 octane. This allows you to run around with 800+ rwhp and not worry.

nice Jim.....you and your shop do good work.

I just wished that HP tuners made a 3-bar SD conversion for '98's.......I'd turn mine up to 20+ PSI.....

Thanks for the compliments guys, I appreciate it.


Nitrorocket- I prefer to stay conservative enough with boost/timing/octane to stay out of knock alltogether at this HP level. I just don't feel comfortable trying to run alot of boost on 93 octane and relying on the knock sensors to kick it down to a lower octane timing table. (which just tells me it should be running better fuel)

Wow Jim those kits are really making some killer power!! We're going to have to turn mine up a notch or two!

I think what Jim is trying to say is that they keep it at a very conservative 625 RWHP for pump gas, the kind of conservative setting where you could beat on it at WOT for 5 miles at a time and have the car not skip a beat. I'm sure you could push it harder, they just don't want anyone with busted ringlands coming back to their shop and complaining. Not to mention this is through a T400 with what looks to be an unlocked converter, so you're seeing a ton of loss through that. 625 RWHP would push you into the 9's with even a heavy F-body.

Your forgetting we're on LS1 tech. Everyone wants 1000rwhp on 87 octane and getting 30 mpg!

Yeah Jim would not tune a 93 pump gas combo to the edge and then give it to the customer.

Andy why don't you hold off until tuning it up until around September, let me catch a bit more, I'm over a second slower than you right now.
