Come in, throw me some input. LQ9 swap. Alright guys, I about have all my parts rounded up for my LQ9 swap into my 99 trans am. Wanted to get a little insight into anything else I may need, also curious if anyone knows anyone with a similar setup to guage where I will sit HP wise.
1999 Trans am, M6-
I had previously made a thread concerning a major smoking issue i came across after a simple header replacement and it turned out to be the worst case scenario. I had noticed excessive oil consumption at about 91,000 miles, along with SOME oil buildup on my #7 spark plug when they were changed and I added a 100hp wet shot ..plate kit (those plugs had over 40k on them).
It always had great oil pressure, ran mobil 1, and never seemed to miss a beat, I replaced my rear end gears and put longtubes on it at 94k and from my initial drive after install I had major blue smoke going on once the car was at operating temp..after a couple days I had gotten a catch can, checked my PCV system, and finally checked plugs, found #7 pretty covered in oil did a compression test and determined I have a broken/burnt ring on #7. compression was 150 across the board with 60-90 lbs on #7 (after oiling the cylinder).
I can only assume I had not noticed the smoking issue do to having cats on it previously...
I just got an LQ9 out of a 05 Vortec MAXX with 79K on it...
-Gonna run/swap/add:
-comp cam .80 over pushrods
-Comp gold valvesprings
-Futral F14 camshaft - 232/234 .598/.598 112LSA
-ls6 intake
-stock rockers with trunion bearing kit.
-ls6 pcv system
-catch can
-hooker LT/s with a 3" ORY pipe
-SLP loudmouth
-swap oil pan/waterpump
-C5r timing chain
-melling high volume oil pump
-stock trans
-diamond stage II clutch w/remote bleeder (just received with GREAT service from Jason @ texas drivetrain)
-SLP lid
-fresh diff rebuild with 3.73's..otherwise stock other than a T/A diff cover
-chromoly driveshaft
and pretty much leave the rest untouched engine-wise.
I would assume I will need injectors fairly quickly, suggestions?
I would greatly appreciate any input/suggestions, along with anything I may be missing to get this thing ready to run, especially someone who has done a similar swap. As it sits im doing this budget build at right about 2500-3000 dollars, looking to have a streetable, 420-450hp car.
thanks in advance
cheers
