Yeah - I've been afraid to cut too many wires incase I need them later. I plan on cutting them after I get the engine in there and getting rid of every unecessary items. I'm planning on retaining the AC too so not sure about that either. I just bought some Hookers Block hugger Headers off ebay - hopefully they work out but they were cheap enough at $200 so not complaining too bad. there is a local guy selling some GTO manifols on CL so if they don't work maybe I can pic those up cheap - they look alot like those LS2 C6 manifolds

HaHa - just noticed my sig - expected completion date - sept 2006 - WOW!

Heres my 4L80E in the tunnel with no dents or cuts. Man these Z31's have big tunnels! I t=will need to mod it a little with mr sledge

Make that 3 of us - 6.0 LQ4 here. I'm using a 4l80E transmission with hope of adding some boost down the road. I thought I was buying an LQ9 but I checked the piston tops and they are dished so it's definitely an LQ4. It's an 05' Electronic Throttle engine that will be retained due to the ease of retaining cruise ontrol with a simple 3 wire hook-up. Right now I'm struggling with oil pan clearance issues and weather or not to buy a new pan from Moroso or Autokraft, or buy the new LH8 Styled cast oil pan from retroLSX.com. they are all about $400 and I'm leaning towards the Moroso pan but the shorter LH8 cast pan from retroLSX looks likea good option too. Thanks for your pictures of the LS2 LS6 manifolds - definitely answers the question as to what headers to use. I'll try to post pics soon. Ken

Yeah, what jason said..... Both are awesome powerplants, both have the cool 80's look to them, and they both have great potential. If I had to choose I would go with a VG in a Z...as personal preference, and that alone. when I had my old junkyard VG on 20psi it planted down 450rwhp with an $800.00 turbo, $500 JWT ecu, $300 intercooler setup and a $400 exhaust, and a few $$ for misc items and some man hours, you are looking at ~$2500 for a screaming 500hp monster and it sounded like a freaking Jet...seriously, it did pretty good deal to me considering most complete turbo upgrade kits cost more than that and make less power. and on a plus side, the z31/VG community are coming up with some pretty trick stuff that won't break your budget either, like the Romulator, Poly engine/trans/diff mount, custom aluminum transmission crossmember, and all sorts of other cool gadgets to set your car apart from the others. If you go with the 7m, do the head gasket at the minimum, upgrade the compressor side of the CT26 turbo, and do some fueling and I'm sure you can do the same thing the VG can. and most importantly...have fun!
