What am I getting myself into?
Hi there. I have been lurking on this site for a while now. I have a fullly built ls/vtec and I am going turbo. I already have a t3/t4 60 trim .60/.63. I also have a custom tubular manifold that is stainless steel. Tial wastegate is also what i got and I still am waiting for intercooler and piping. I think I wil be using neptune for tuning but I am not sure. What are other things I should know about when going for high boost. I am aiming for 450 horse

Re: What am I getting myself into?
well since you have an LSVTEC I would really look in to what compression ratio you're at now with thoes pistons and that head.
Go on the SRP site and also open up the Cspeed compression calculator for B series engines, find out what your total CR is with the headgasket you are using, the lower the better.
For my B16 for example (semi built w/ pistons/rods but no sleeves) I'm at around 9.5:1 with a .045 headgasket and SRP 9.0:1 pistons, kinda high but It will be fine. you want to stay around the mid to high 8:1CR or the mid to low 9:1CR anyting higher and you are at more risk of detonation.
NOTE: the CR that SRP rates your pistons at is based on using a .040" headgasket, it is not with the factory HG, just remember that.
Also remember that the Cspeed calculator is not 100% accurate and gives you an approximate range give or take.
Since you said you have all the stuff to physically turbo your car then I would get a really conservative basemap made and go to a tuner with your setup, no point risking a fully built engine.
450 is alot of power by the way, maybe you can show Hotrex what its like to go past the 400 mark without destroying sleeves, and post some pics of the setup along with some good **** for the rest of us.

Re: What am I getting myself into?
I will post pics once I get time to work on it. The problem I have is there isnt a tuner up here in alaska. There is a dyno up here but the owner uses it for personal use. I was going to use the headgasket from the ge ls/vtec kit. Will that one be fine? Anybody know the size of it off hand? thanks for the reply
