Turbo info I have the old TTi system with a Garett 70 turbo. I have the bigger down tube and air to air cooler. I know I need the bigger manifold which is $750. I would like to go with a larger turbo. Who make's a bigger turbo that would fit in the same location? Im building a 408ci with 8.5:1 cr. Does anybody know how to get in contact with

you dont necessarily need the bigger log, but with the 408 CI engine it would be a good idea.
also when getting the bigger turbo id go with a 1.06? AR housing instead of the .96 it usealy comes with.
you could also contact tubotech if you havent already

SSC5R, several builders make turbos that will fit in that location. The only problem with that kit is the on-center housing. Contact me anytime, I can go into depth with what you need and runs some numbers for you on whats best for your combo.

I was trying to order the manifold, cross over to the other manifold pipe and exhust pipe from QMP and they wouldn't sell it. I don't like the TTi version all that well. Who make a system that like the QMP? Oh, what kind of power and boost can I get from a Garett 70? Thanks.
www.stainlessworks.net made qmp's parts.. but they are not a direct bolt on to a turbotech system that i know of.
:edit.. how much horsepower are you looking for and why do you think you need a $$408$$ to get it.. just trying to save you some money.

Well first, 408ci motor and a T70, thats a big no, no. Your going to easily push that turbo well beyond its choke line. You will get alot of heat build-up and very high IAT's. The backpressure will be ALOT also due to the T4 flange and small turbine housing. On top of that, I would not run a log manifold design with a big cube motor like that. It will run in-efficient, not to mention you will have to taylor a cam with a small duration on the exhaust side to keep reversion down to a minimum and low amount of overlap. You can make power with the system don't get me wrong, but you will be way under the potential of what that motor and a good flowing system can make. I suggest a larger frame turbo, if you physically can't fit a T6 style flange turbo in, use at least a small frame PTE-88 with a .96 A/R. If you want quick spool and want to stay around the T70 range, then go with the Master Power GT-45. It uses a larger frame exhaust even though it still uses a T4 style flange. The turbine wheel is an S class wheel which will help reduce backpressure, plus the A/R is a 1.05 is a bonus. The turbine wheel is between the 76GTS/GT42 and PTE-88. The GT45 is good for about ~1000hp crank and the PTE-88 is good for ~1250 crank. If you do decide to stay with the TTI system or QMP logs, then you will be limited to your turbo selection since you will have to stick with an On-center housing. They flow less, and you can only go as large as the PTE-76GTQ. I can supply you with any unit you need thats not a problem. But first you need to decide on the exhaust you will channel it through. Also once you have decided on a combo, then you choose your cam accordingly.

Im getting a C5R block here soon. So I guess Im going to be a 427ci motor. I just got a Fast 90mm intake and T.B. Im looking to make 800 rwhp. Thank you for all your help guys. JZ 97 SS 1500, what combo do you think I should go with? I'll go with whatever you think is best.
More then likely right now the TTI race setup is your only choice. The PTK system won't be out until august. I would just buy the headers and such and then we can talk more in detail about what turbo you will need. Just e-mail me or pm me your phone # and we can discuss it.

Just my 2 cents, i'm running a 360" motor (4.1" bore and 3.4" stroke) and at 775 RWHP it's actually driveable on 17" BFG drag radials. If this were a 400+ inch motor with a 4" stroke, it would be making well over 900 torque to the ground and would light up the tires if you gave it any throttle.
Just to give you something to look at here is a rough estimate of the air that a 408 consumes at different PR, rpms, and this is using a EV of .85 which real world it will be dynamic, IAT's of 125 which is about normal for a good A/A system. This will allow to pick a turbo better suited for the combo. Of course it does not take into account T4 and T6 housings which flow will change with those factors.
