IGY

T66bb with a 1.00 AR Q-trim exhaust will be an excellent choice.

IGY, why didn't you mention the 68-1 yet? What turbo does that option come in? I'm guessing it's a variant of the T04 somewhere. Would that not be suitable for my needs or did you just forget to mention it?

One thing that I forgot to mention IGY.... A 1.00 exhaust size isn't available. Only .84 or 1.15 A/R. Is that going to make alot of difference. Also, I don't know how it will affect me. Is it going to take longer to spool or how does increasing your A/R affect the performance?

Smaller the turbine a/r the faster it will spool, but it will limit it on the top end/choke the motor.

Still no answers on my 68-1 question??

IGY

The 68-1 is in my opinion perfect for what you want. It will make just as much power as the T66 at lower boost, and then it will make more after 15psi. It is actually in between the T66 and T70 as far as how much air it pushes, but it does it at lower boost. I have a 67-1 which is the predecessor to the 68-1. The reason I didn't mention it is that most people complain about the price, because only Turbonetics makes it. I have also noticed that Turbonetics no longer has it in there catalog, so I assumed they didn't make it any longer. If you can find one and aren't worried about the price, this turbo will make you happier than the T66.





You should be able to get a 1.00 Q-trim divided housing or a .96 undivided housing. 1.15 is going to make you spool later and the .84 is going to choke the bridge(will probably rev to 9k pretty well, but will make less hp and have a smaller powerband).

BoostedRex, I am running a T-72 BB and unless You want to run at least 19 PSI dont bother with such a big turbo. It takes untill 4500 RPM untill You are spooled and then hang on. This big turbo is meant to be running at least 22 PSI and should be tuned for about 26 PSI. I am slowly working My way up to the low 20`s but am finding out My fuel is going to come into play. I have an extreem fuel setup with a sumped tank/10 AN lines and an Aeromotive 1000 HP pump/750cc/1600cc injectors and they are going to be maxed out before I can reach 25 PSI. I would get the T-66/1.00 exhaust BB which I think is the perfect size and run it at 18-20 PSI. It would kick but on the strip and still be fun to drive in the city. Be ready to upgrade Your driveline.

Sub-Zero,



With those injectors on a ported rotary, you should have enough fuel for 550RWHP @ 85% inj duty. Why don't you think you have enough? Does the Aeromotive flow enough volume at 66psi? The Bosch '044 does.



I bet your T72BB SINGS!

I think I've decided on the T-66BB unit. Everybody think that would be a good idea with a half bp? Just thought that I would ask. Laterz.
