I will trying the the kit with stock 02 manifolds and I also have some jba shorties on tap for comparison, I thought about the reg kit but instead of paying the extra 1000 for headers I found jbas for 300 so with some coating the kit will be pretty close to the same design other than the backwards driverside manifold. the car isnt much of a DD anymore so why not someone has to try it lol.

this will provide some very good comparison data
I'm interested to see how the two phamspeed kits measure up against eachother
I hope every thing works out well for you

I would go with the 76GTS if its used on the street. The turbo has made 987rwhp on a 355 LT1, spools 500-600rpms faster and takes alot less space. Also the 88 comes with either a 4" DP or 3" donut flange which wouldn't bolt up to the phamspeed kit unless its a custom DP. Also, running a 4" downpipe underneath the car would not be wise.

Gary, the LS1 kit that was installed on our project vehicle for testing is now coming to me 
. The project vehicle owner decided to move up to a C5 Vette and bought our Twin turbo kit for it instead "can't blame him on that one" 
. The system in reality will perform just as good as the LT1 system as long as you have the motor to take it.

I think the T76 would work better for the streets but like he said, it won't see too much street and I don't think the stock manifolds are any way resrictive for what he wants to do

The 76GTS only needs a 3" DP. The 4" I was refering to the T88 if optioned with the 4" Vband. You can run the 3" donut flange also, but no sense unless your looking for #'s above 1000rwhp. Also the 76GTS clearly outspools the T88.

send me the 88, ill fit it to my car.
also jz what psi was that 987 at? if i carried mine it would have been maybe over 930 at 23psi.. but i'm not real sure how comparable my turbo is from this gts one.
