do they have egt bungs in them or do you have to drill and tap for them? Will the work with any plug configuration angled or straight? will they work on a lt1?

thanks sorry to ask so many questions

They are drilled and tapped for 1/4" NPT from the factory, any plug configuration will work, and they will work on a LT1.

thanks 1795.00 is the price right? Ill be in touch and ordering some from you.

again thanks for all the help

Yes, that is correct. I look forward to setting you up. :thumbsup:

How about raising the turbo flange a little bit? I've heard of guys running bigger turbos and having clearance issues on the valve cover and a 1" spacer fixed it and you can still take the valve covers off without removing the turbo. Maybe as an option for those wanting to run bigger turbos on these manifolds?

Do you recommend polishing, chroming, powdercoating or heat coating these manifolds and would it be beneficial to port and polish the insides for better exhaust flow?

We no longer offer the spacer plates but they are available through most turbo resellers like Turbonetics or PTE.

Polishing, powder coating and chroming is up to the end user and his/her preference of appearance. Porting & polishing the inside of the manifold can definitely effect overall flow, performance and spool up ina positive manner.

Finally finished assembly on my banks twin turbo truck.

I got the wrong springs for the wastegate and I am going to a 2 bar map sensor for more accurate tunability.

My tuner tells me since I am using the innovative boost controller, I can have all the boost I am crazy enough to put in the motor.

I finally understand the wastegate. I think the thing I didn't understand all along was that the exhaust coming from the motor is not going to push the valve open, it is the boost from the intake side that does that.

At any rate, I think you gave me 12 pound springs and we ordered some 3 pound springs!!!!

Quite a difference.

I can't wait to get the truck on the road, my tuner is Colvin Automotive in Austin, the guys that built Lance Armstrongs GTO on overhaulin. He has had it for about a month and a half now.

Hope all you Banks guys are doing well, I sure wish the forum here was more active and I also wish I had more than 10megs of webspace to keep my pics up.

Good luck to all you installers out there in metal fabrication land and plumbers world. It's quite a project.

Rock on,

Can you tell me what size turbos come with the twin turbo kits?

Im looking at a turbo for my Typhoon that a guy is selling that says its from the newer twin turbo kits and says its a T04B with a TDO6 Turbine wheel in a 1.00 a/r housing with a 25G compressor side?

How does this turbo compare in size to something like a 60-1, or T67, or like the PTE 52 or something like that?

IS this to much turbo to run on a midly built Typhoon 4.3L V6 with a 2800 stall converter? Will it have lots of turbo lag?

Thanks

That is a turbo we used about 20 years ago. They are good turbos and are still used today by many different tuners. The actual size of the inducer on the 25G compressor wheel eludes my memory right now but I would guess around 50-55mm. Running ONE of those on a 4.3 might be a viable option but using two will be out of the question. IMHO It would be extremely laggy with two turbos on that size motor. It probably wouldn't make positive manifold pressure until 3500-4000 rpm.
