I have a 99 LS with 86k did a compression test and got straight 185's across the board. I recently pieced together a turbo setup and was wondering what everyone thinks of it and when do you think i will build full boost at..

Garret t3/t4 57trim .63ar
Blox mani
dsm injectors w/ resistor box
greddy Type S bov
Custom 2" and 2.5" Ic piping (2.00" piping from turbo to intercooler inlet & 2.50" piping from intercooler outlet to throttle body)
Custom fmic (28,6,2.5) bar and plate
p75 ecu chipped for neptune
AEm 3.5 map sensor
ngk .30 gapped colder plugs
Tial 38mm wastegate (.5bar spring)
custom dumptube for wastegate
evo 9 fuel pump (rated a little over 200)
custom 3" DP (with custom 3" testpipe)
3" straight exhaust from testpipe
slimer radiator fan
all necessary oil lines and t-bolt clamps and couplers

thanks

 

seems pretty good.

just a few questions

why did you get a 3.5 bar map sensor when you couldve gotten a gm 3 bar for cheaper--your 440 cc injectors wont let you boost that much.
why didnt you just go for the walbro fuel pump

i think thats it

good job choosing the type s bov, I have one and I absolutely love it.

 

This is close to the 'no bench racing' rules, but I guess it can't hurt. I'd say about 5.5k you'll have 25psi. Realisticly, you won't want more than 10psi on 450cc injectors if you want it to last long. 450's are good to ~300whp with a strong pump, and I've seen 57trims hit 300+ with 10psi. Anyways, 4750 would be a good start for 10psi on a stock block.

I'm curious why you want the 3bar and evo pump. Unless you're looking to do a single hail-mary run at 28psi or get a 2nd set of injectors, it won't help you in the least. I've seen stock LX pumps run past 200whp, and stock gsr pumps to 300. But if you got both for free, then why not rock them, right?

 

I decided to go with the AEM 3.5 map sensor since my tuner told me it would best fit my setup. He said the 3 bar map sensor arent jus as good. The fuel pump was off a Evo 9 (5k or less on it) which was one of my buddies and he gave it to me for $10 and i asked a few shops near by and they said it shoudl work fine. I'm hopin to build boost b/w 3-4rpm. I hope everything goes smoothly and thanks for every1's input.
