I have been wanting to do a V8 swap into my Sky. I was getting 312 WHP and 352lb/ft out of the 4cyl LE5 engine with DDMs stage 3 SC setup with some other additions, but it wasn't enough for me.
The engine I bought cost twice as much as I wanted to spend, but I discovered the cost of rebuilding an L33 engine plus intake, cams, heads, etc. could have easily cost an additional $2k+. Definite plus side is I get a "brand new" engine that I really don't have to do anything to and can leave as a NA for the power that I want even though I still want a supercharger. I don't mind the iron block weight penalty. Norm's Viper hood and front side fenders will help offset the 75-100lb weight diff between iron/ alum blocks. I save a little more weight since I have aftermarket seats.
So, I've been doing a lot of reading to try and figure out everything else I need. I also want to use the rear portion of the existing 2.5" exhaust (made from Race Precision (RPi GT exhaust)). Roughly $2500 remaining in a $9k budget build. Here's a list of have/ need.
Have:
- (ad read) "Iron block ls3! Life started out as a 6.0 block (LQ9) bored and balanced at city motor supply with documentation. Assembled with the stock ls3 bottom end with new bearings and rings. To finish off the bottom end motor was buttoned up with a moroso oil pan for clearance in just about in vehicle with remote oil filter fittings lines and mount, -10AN. Cylinder heads are stock gm 821 heads milled by kim barr racing to a mirror finish. Camshaft is lg motorsports g6x3 cam! Timing was upgraded with a double roller timing chain from comp cams, and a ported texas speed ls6 oil pump. The heads are kept on with arp head bolts. Comp cams double springs, titanium retainers, locks, and seals are installed on the heads to keep the valve train in check. BTR hardened pushrods connect to trunion upgraded stock ls3 rockers. Now for the intake. The intake is stock ls3 upgraded with holley ls fuel rails with ls9 injectors installed. To finish off and close up the motor is a fast 90mm throttle body. As for accessories a starter is installed and a slp 25% underdrive pulley. Think that about covers it. I had this motor built and assembled for a project that is now going another route, LS7! I used quality components ones any car enthusiast would appreciate. I also have a modified harness that is about 80% complete, needs to be lengthened, but is routed and run tight and give a flush finish."
- TR6060 transmission (pulled from a 2010 Camaro with only 20k miles)
Need:
-short throw shifter
-rear differential mount
-drive shaft
-radiator w/ fan(s) (Griffin?)
-air intake w/ filter
-misc exhaust pieces
-hoses
-tune
Advice/ tips are welcome. Missing anything?
