buschur cast hta35
so this is my problem, I have a buschur cast hta35r .63 kit and want to go bigger, can I upgrade the back turbo housing to a .82 or .86 the way it is sitting now or do I have to do something else, I was also thinking of taking the cast manifold off and getting a tubuler manifold any help will be great thanks.

While Mellon did well using the .63 a/r, that does not mean the larger a/r wouldn't have benefited him as well. You should see top end gains going to a larger A/R. A reduction in the flow restriction within your exhaust will provide benefit regardless of boost. However, the gains may be more significant at higher hp levels/higher boost. The expected gains will really be dependent on whether the a/r is the limiting factor at this point.

I have all the supporting mod my motor is back out of the car I am dropping in rods and pistons plus main stud and bearings, I also have the dual pumper and the rest of the things so I am just wonder I can just buy a .86 or .82 back housing for the turbo plus manifold and do the upgrade. I want 700 plus whp

I have been turbocharging cars for more than 13 years and used to sell Garrett Turbochargers so I do speak from experience. You're a typical pompous dealer on this forum who tries to belittle others who provide a different point of view. I simply provided my opinion on the matter and didn't bash you, but you somehow feel obligated to bash me.
I am always open to a good debate so let's go. You swapped to a larger compressor wheel and turbine a/r so perhaps you didn't see gains because you had flow restrictions on the intake side of the motor. Clearly you don't understand your own example and justification.

MODERATOR, WHY IS THIS VENDOR BASHING ME FOR PROVIDING MY INPUT?

p.s. now that you've mentioned your goal, the .82 and tubular header would be ideal for your setup
You are correct and that was my point as well. You only need to look up flow numbers on Garrett's website to understand a larger A/R flows more when talking comparable housings. I was very careful in my initial post to say the following...The expected gains will really be dependent on whether the a/r is the limiting factor at this point. My point was directly applicable to Mellon's issue that he lacks flow on the intake side of the motor.

you guys keep talking about theory and I'll keep producing the results. Show me somebody that got significant gains at 30psi on 93 octane with a 35R by going from a .63 to a .82 on a well prepped evo. I said there will be gains with better fuel and higher boost.

@ 30 psi on pump there simply won't be enough gains to justify the swap & the increased lag. 40 psi on e85 is a totally different story though. I think both of you are correct in a sense, just debating based on mis communicated facts.
thanks for the inputs but you guys haven't answered my questions yet but on with those great comments to each other.
I WANT TO KNOW IF I CAN JUST CALL FP AND ORDER A BACK HOUSING AND THATS IT THANKS.
and thanks mellon for those advice to get 700whp
