Yep, that covers 99% of the problems. I've only run into a couple of AFM issues and one bad ECM. Agreed. The beauty of it is that its such a simple system, it doesn't usually take much effort to freshen them up. I usually spend more time fixing other peoples 'fixing'. Amen.

I'll be the first to admit that the OE EFI is confining in terms of power... but in no way is it unreliable. If it is in 'good' condition (as you say), it is nearly bulletproof. I've owned and tuned countless systems and reliability has never been the 'nose wrinkler'.

You're expected to share

Olie, This probably doesn't fit your "cleanest install ever" parameter, but you could use the distributor quill shaft to run a 'cam' sensor. Certainly not the only way but, I found this to be the easiest way. If you come up with an elegant alternative solution I'd love to hear it! Keep us posted.

See it all the time with airports as well... People move next door to an airport thats been there for 80 years, and suddenly, they're pissed off about planes. Sorry for the off-topic... just had to vent.

Interesting Tony, I didn't think anybody had reached that level of efficiency. Cool stuff.

Awesome article! Thanks. If it matters... Savage's car was a VG30ET. Dave Lums 510 is a VG30DETT... to my knowledge, the only one in the country (also with an R180LSD for years now as well). I hope this wasn't 'casued' by me? I want to apologize for being stubborn with Lunar240z (over 240Hokes car). I guess I'm a little too passionate about that sort of thing Take care Buddy.

Well said, Tony I'll second that... and I'll go so far as to say always has higher exhaust pressure than intake.

My '72 240Z with LT1/T56 weighed 2450 (dry). This includes R200 LSD, sectioned struts, rear disc brake conversion, coil overs, CV half-shafts, scratch-built fuel tank, power steering pump (recirculating), aluminum driveshaft, LT1 EMS, and Panasports. P.S. I weighed it on bathroom scales... Is that OK?

Dapiper, That would be great... I would love to see it. I get the feeling we're talking about two different things... maybe the O-scope dump will clarify. Thanks,

Maybe food for thought for the next guy?

I remember, when I installed my Nismo LSD, I ended up pressing one of the bearings on after inserting the center section. There may be a better way, but at the time, it seemed the most appropriate.

Mike, I didn't really mean it THAT way

I think Pop is right on track. I may not purchase the same things that Pop would, but there would most certainly be other items (every one wants something different) that would cost roughly the same. In my opinion it is wise to give benifit of the doubt to the person whom has done it, rather than whom hasn't. That said, olderthanme, may I suggest you PM a couple guys that have COMPLETED thier LS swaps and ask them their thoughts? *edit* If I were building an LSx/T56 Z, I would not budget ANYTHING less than $5k... and that would be for a largely stock motor.

Listen to Pop.

You meant LS6, right?

What he said

I remember a time, shortly after finishing the LT1 240Z, that my wife, with me shotgun, was 'done with 3rd and reaching for 4th'... on our RESIDENTIAL street. Needless to say, I had to stop THAT. The point remains, however.... yeah, she likes cars.

Nailed it. Thank You.

Cary, I was just thinking about this a couple weeks ago. You're talking about running needle thrust bearings between the spring and perch right? Have you tried this? How much benefit are we talking about? Would they normally go top and bottom (of spring) or is one bearing per spring typical?

Guy's, This was never intended to be precise. I kept hearing rumors of 75lbs, 60lbs, 90lbs, etc. I had reasons to believe otherwise. We did what we did to see if there was a SIGNIFICANT difference. We didn't find it in the short block. Yeah, there are a few small parts missing but not 50Lbs of them. Yes, the LS1 is lighter. *If* its 55 lbs lighter, it not in the shortblock.

Do the parts weigh more installed then they do on top?

Not true. Plenty V8Z's get over 20. My LT1/T56 240z got 28+ on the highway. If you make big power you WILL burn fuel, regardless of engine, period.
