One of these will probably land in my Impala...

acceleration video finally... short shifting still spins the 315 drag radials in first and that wasn't even off of a clutch dump. This was done after my clutch master cylinder drill/adjustability mod so now I can hit the gears 10000x better. I'll get a better video when I get a droid GPS dock.

The salvage yards are full of them now. You can get a fire damaged long block $500-$800 w/low miles. They usually still warranty them. Just have your swap ready. $800-$1400 with high milage. Sometimes you can still find low milage under $1500

low compression... time for a procharger

Car sounds great! I've still yet to see anyone really add boost with VVT. It should offer all the same benefits regardless but I've only seen a couple shops talk about building boosted VVT engines I havent really seen any MB users do it and post up about it. Not saying it hasnt been done but the info is scarce as of yet.

yeah, I keep saying that this is a brand new technology to the pushrod crowd and it will take a LOT of getting used to.

I know Mast has at least one crate motor with a TVS 2300 supercharger on a VVT motor. I bet its a beast on low end torque. I'm dying to go boosted on my L92 in my 240SX. I wish Edelbrock would come out with a system for the truck so I could line up with the pulley. I think their low profile supercharger just might get under my hood.

This is appetizing, I have not driven a stick in a LONG time. I'd like to do this to a fox body.

Do you run the drag radials all the time?
What rear gear?
OEM clutch?

There was mention of the VVT motors having less than desirable lifters, did you swap them?

first time hearing about these LY-6 Awesome car/ engine!!!!

I run Nitto 315 Drag Radials all the time, I have to. The Sumitomo 315's I had would just spin no matter what I was doing, practically. The Nittos have a hard time holding on in the cold, but once it warms up a bit it should be better. I'm still seriously contemplating a cam but haven't totally decided yet.

Rear gear is 3.42 (the m12 t56 has REALLY short gears, so I don't know that a 4.1 would be of any benefit there).

Using a LS7 clutch/PP/Flywheel from a LS7 take-off on ebay, new. It's a great clutch but you MUST do the drill mod/adjustable stock master cylinder mod to make it work properly.

I've done the drill/adjustable master cyl mod and that is, in particular, is on my top three best mods list, easily.

As far as VVT lifters, I don't think they're any different than the LS3/7 lifters.. it's only if you have the AFM motor that you get the "bad" lifters. Though "bad" is relative to the goals of your project.

I'd like an AFM motor for a truck to help boost the fuel economy, that's for sure.

Pillangenburn or anyone running a T56,
How'd you wire up the T56 reverse lockout and skipshift? Do they need to be wired up? I'm running the same exacty setup, LY6/T56 but have no harness, as it's going into a 69 GTO.

Dont need to wire in the skip shift. If its not wired it does nothing. Reverse lockout defaults to lockout however so you have to wire that in. Most swap guys wire it to the brake pedal switch so unless your foot is on the brake it wont go into reverse

Awesome build. I've been sitting in the back reading this thread for some time. I've got a '99 SS with a LS3 swap that I was contemplating converting to VVT. The benefits seem to be too amazing to ignore. I didn't do the conversion it was purchased this way. From what I have read seems to be pretty strait forward, swap in VVT parts from an L92, COMP phaser limiter, TSP VVT-2 or 3 and then get the tuning figured out. Thats were I get confused... do I need to run a ECM from the L99 or can I flash the current one I have. Circuits and wires make my head spin.

Am I naive in thinking this to be so "simple"?

Unfortunately this is not really feasible as of yet. These new e38 PCM's do not take kindly to custom OS flashes it almost always destroys them beyond repair. So you would need a matched VVT PCM along with the corresponding mods you listed above. At this stage as cool as VVT is I dont think I would bother converting an LS3 over to VVT just yet. Theres still a lot of confusion into what it takes to get these things dialed in with perfection and its not like adding VVT will produce a ton more power than a non VVT LS3 would. It is a gain but for the cost to buy the parts and the work involved to convert an LS3 over I think you could get more bang for your buck if you spent it elsewhere. But in time as this stuff becomes more and more popular it could get a whole lot easier.

The shear amount of LY6 swaps going on now is proof of this. Lots of guys are going forward with VVT builds now

I kinda figured this much. Its all new and uncharted territory for the LS world but I'm glad to see more people embracing this technology. And I agree that the performance gain is minimal and in the case of my cars current setup the VVT setup would produce a little less. Just comparing dyno charts for TSP's 229/236 and VVT-3 because my car has never actually seen a dyno. IDK its mostly the novlty and "coolness" factor of it all that has me intruiged. The power and performance gains, like you said, will come with time.

BUT... if one should feel compelled to make the conversion happen, its a matter of wiring up the VVT PCM and finding a tuner to test his skills. What about an ECM from MAST?

sorry if ive hijacked...

Just read all 10 pages. Im currently doing a ly6/t56 swap in my Sonoma. Havent gotten to the wiring and ecu part yet. Wonder if ill have trouble with my speedo also? Is the e38 ecu that your using the only ecu for vvt? What do newer non vvt manual cars use like the new camaro ls3/6speed? I have the TSP vvt-2 cam in mine cant wait to get her running. Keep up the great work!

you will have a problem with the speedo

Have you traced down any fixes? Ive been following your thread on hptuners and it seemed that you were onto something.

pillagenburn

iTrader: (2)

nah, not on to anything - HPTuners was little/no help. Which doesn't surprise me, the model year vehicle I pulled the LY6 out of was 2007 and the latest stable HPT release is dated June 2008 so I didn't expect that they'd have a stable build capable of properly flashing the e38 ecu in that timespan. Wishful thinking, maybe.
