I am having no luck getting the motor to run like it should. I guess I thought while the motor was taken apart (mostly) to change the head gasket, it was a perfect time to add some HP.
The motor was stock but had a 16g and FMIC when I bought it. I mainly did the cosmetics first (body and interior) and then ordered DSMlink. I installed that and unfortunately I overlooked something and it over boosted and the head gasket was the victim. So I decided to start ordering parts while it was down.
The parts that I installed during the downtime were:
FP hta68 turbo that used an external wastegate.
New O2 housing made for the Turbosmart 40mm wastegate and dump tube.
S90 throttle body.
WeaponR sheet metal intake manifold.
CX exhaust manifold.
AEM afpr.
Bosch 1600cc injectors.
Walbro 255 fuel pump and rewired.
600hp rated FMIC and new piping for the turbo set up.
Agency Power 4" catless exhaust.
9.5mm plug wires.
STM short tube intake off turbo with K&N filter (No MAF).
Speed density set up with IAT sensor and GM 3bar with harness for factory plug and play.
Vacuum hoses deleted using diagram found on this site and using a turbo timer instead of coolant lines ran to turbo.
Blox boost controller (turned all the way down).
And obviously New gaskets for the head, intake manifold, exhaust manifold, tb and have done boost leak tests and checked sensors.
The headgasket blew 5 months ago and have not been able to get it to either idle or drive properly since everything has been installed. Rix Racing did a remote tune and was cut short and determined that the 850cc injectors were bad so that's now replaced with the 1600's along with a new fuel filter.
It's like a monster that has so much power but ended up having down syndrome. Did I do something wrong in choosing parts or is that just a bad set up?
Any suggestions would be so appreciated and have posted logs and have done everything suggested and still can't get off the handicap bus. I'm so excited to drive it running properly and so proud of the time, blood, sweat and tears I've put into it.
It's keeping an ok idle but can't drive it for more than 5 feet without it bogging down and dying. Should I pull the motor and completely start over? Have I invested wasted money?
Basically where should I even start or am I just missing something small???
