i have a 408ci stroker kit and i am THINKING about selling it to build a 370ci motor being i bought a PT88 turbo and it is on the verge of being to small for the 408ci

at the time it is only a thought... i am still tryin to talk to a fem folks on what would be the best set up for me.. if you can help pm me or just post it please

2002 full size silverado regular cab
KB custom front mount PT88 turbo w/4" DP, 2.5" cross-over, 3" log
4l80e
230/230/ .592/.592 114

STREET TRUCK!!!

 

I dont think its too small... but it should spool up quick... PT88's are great turbos i say slap it on and see how ya like it. its easier to buy another turbo than build another motor... IMO

 

i haven't built the motor yet... thats why it would be easier to make the choice now!!

 

I say run that turbo on the 408. Should make great power

 

It all depends on how much you are actually trying to get out of your setup. If it is going to be all out race setup on race gas and you plan to spin the **** out of I then the pt88 will run out on top. If it is more of a crazy *** street setup then the 88 will spool quickly on that motor and will be a lot of fun. You could always go ahead and upgrade the Turbo to a gt series and you wouldn't have to worry about it.

 

i don't have the money to upgrade turbo, get kyle to redo my kit, ect...
would be real easy to sell my motor parts and buy new ones and put money in my pocket

but this truck is being built for the street and will do whatever 93 pump gas will allow it to do!!

 

I say finish the 408... put the PT88 on an call it good. It will spool quick but should still put down more than enough power. On the street it will be a beast if you can hook.

 

lol.. i had to learn to hook a SVT lightning with 719rwhp so i might be ok...lol
plus i like to leave black strips from 70 to 120mph.... atleast my lightning with the gts-76mm would i hope this one will...lol

 

that is something else..
why can my 331ci 8.9:1cr modular motor make 719rwhp@20psi w/76mm through a 4r100 trans
but
408ci 9.2:1cr ls motor with 16psi through a 88mm only make 853rwhp through a 4l80e and lifted a head??

it seems like the LS motors don't like the boost like the MOD motors do or am i wrong??

 

I was running a 346 with 9:5.1 cr and 14 psi and made 709hp 769tq.

the pt88 will work just fine on that 408. what A/R housing does it have?
