so after a lot of wait and gathering of parts... that car is Boosted. dyno sheet will be up when i can scan it. but it did 160 to the wheels on 5lbs. had to stop before it kept going higher due to Boost creeping. :-\ but ill have pics up and dyno soon!!

feels great

thanks for all the help everyone who has given me advice and parts along the way!!

Pics or I call BS

haha dont worry Tweak. im at work. get off at 7. Pics will be up Tonight.

ok..posted pics. now i just need to get a copy of my dyno on the comp.

great work.

what PSI do you plan to take it ? don't tell me you did all this work for 5 PSI only.

thanks! and hell no im not just trying to stay at 5psi. lol. lookin for 12.

post a list of all the mods you did

looks good.
like the top mount turbo setup, curious as to why you mounted it with the compressor on the passanger side?

X2

ThoughI would imagine for FMIC it may be a little less piping.

-Terracar

thats exactly why it was mounted on the compressor side. just made the piping layout easier and more accessible.

Mods are:

460cc Denso Injectors.
255lph Walboro Fuel Pump
T3/T4 "ebay Special" turbo. .57 trim
Internally Wastegated with 6psi spring.
2.5" IC piping.
Big Greddy FMIC
Apexi Neo
HKS SSQV as of 1 hour ago.
Apexi Turbo Timer
custom 2.5" downpipe
2.5" full exhaust
JGS Tools Oil feed and drain kit

I guess this explains why you're getting boost creep at 5 psi.

looks good man keep it up!! update with dyno sheets please!!

but it creeps all the way to 12psi

Thats what happens on internal waste gates with free flowing exhausts.

so i either need to Bore out the whole in the wastegate more, or buy a lower spring if im not mistaken

no, tune it for 12psi. 5 pounds gets old quick.

i was thinkin about that, but i wasnt sure what the situation would be. if it woul still creep higher and higher.

I have the same boost creep problem. I have an internally wastegated turbo with an 11psi spring (it's the smallest I could find for my turbo) and it creeps to about 15psi. I'm sure it'll creep higher than that but my MAP sensor won't let it. I plan on getting a Tial external wastegate with a 7 or 8psi spring and turn it up to 10psi. Hopefully that will help the creep issue, if not I'll be in the market for a new turbo with a bigger exhaust housing.

yea i actually just took apart my buddys old t3/t4 turbo that has the same exhaust housing as mine. im gonna take a dremel to the hole for the wastegate and open it up some more. *according to my tuner, that will help with the boost creep* but im orderin my MBC in a few. so ill get that and turn down the boost for now.
