Pros and Cons of TWIN TURBOS ON A MODIFIED 20B

[Mir]

Hi Guys,
 
Since I am building a new manifold, I am having wiered ideas going through my mind. :Viking
 
Thinking of installing two Greddy T88 34ds on my 20b, what do you guys think?
 
Or
 
Shall I just stick with my commitment to buy BW S595 OR S475?
 
I like to do things once, hence I dont cut corners and go for the best part available!
 
If everything goes well, I would like to have a bit of fun next year
 
Any info is appreciated.

You would be ebtter off with two slightly smaller turbo\'s than the T88 or one bigger one I think.

perhaps twin GT4088s or a single GT42?

Don\'t forget if you go to twins you will have other fabrication to do for your intercooler inlets.

Keep it simple comes to mind for me, one turbo, GT42 maybe. Or go for the biggest size on the s400 series in BW range. The s500 series are huge.

S475 job done, it will mash you into the seat when tuned up. It will make mincemeat of third gear in a stock box, best get some quaife internals in there.

Have you looked at any spec sheets of the BW turbos?

Grant the metal fabricator I have is more than competent to do the job.
 
I just want to build something which does not let me down in future. Now the car is worked on and according to Carl Hayward\'s theory "its an oppurtunity for further development" I am committed to develop it more.
 
I want something really awesome so that the piston rings don\'t fry out :Hammer:D:D:evillaugh:evillaugh and I run a fast quater mile too:Party. I am hoping for low 9s on a street set up without choping or cutting anything off.:bandit

Gearbox wise, Pip has already looked into it. He is trying to find a guy who can modify the bell house and etc etc for us. "That" gearbox is more than capable to handle up to 800RWHP.
 
ohh!! I am preparing for next year.
