tbolt clamp sizes

[tntdiablo]

i am installing a precision front mount and i need to know the size clamps that i need,it looks like 3 1/4" for the pipes,but what size do i need for the step down hoses to the throttle body and the turbo?turbo is a ta60.thanks

Stock t-body takes a 2.5" t-bolt clamp.
70mm t-body takes a 3" t-bolt clamp.
TA-60 turbo takes a 2" t-bolt clamp at the turbo and a 3" t-bolt clamp at the intercooler pipe.

IC pipe to IC is two 3" t-bolt clamps.
IC pipe from IC to t-body takes three 3" t-bolt clamps and whatever size t-bolt clamp to match your throttle body.

Here are the part numbers that PTE uses.

2" T-bolt clamp = Five Star 235-69
2.5" T-bolt clamp = Five Star 200-76P
3" T-bolt clamp = Five Star 250-82

You will need a 2" to 3" reducer hose to go from your TA-60 to the IC pipe.
You will need a 2.5" to 3" reducer hose to go from a stock t-body to IC pipe.
Or, you will need a Straight 3" hose to go from a 70mm t-body to the IC pipe.


And just for reference sake,

3.5" T-bolt clamp = Five Star 250-83
3 3/4" T-bolt clamp = Five Star 250-94
4" T-bolt clamp = Five Star 250-100


Hope this helps.
