The rustiest and only one I'm saving is mine. I'm probably crazy to do it, but I already own it and it's "my" Z and it will live again. Below is my passenger floor for reference. Commit to the time and you'll get there.

Looking for a OK condition 2+2 roof / pillar emblem set. The ones with the "Z" over orange. Let me know what you have. Thanks

FYI to others who might try this, the pump found on the vehicles below is easier to come across than an LT1 unit. The other nice thing is they have a nice section of wiring harness that has a dedicated fuse/relay block you can chop out to make wiring easier.

FYI, I bought this eBay can and it's worthless. There doesn't seem to be any separation of oil/air.

The standard two bolt ones for a T3 and similar fit, so it should be easy to find one.

Well, something didn't like the punishment too much. I've developed a problem with the number one cylinder. It still runs strong, just 5 1/2 cylinders strong though. Still only boosting to 10 PSI. I saw some excess blow by coming out of the VC breather one day and decided to do a compression check. #1 = 120 psi (dry and wet) #2 - 6 = 165 psi dry Next, since I don't have a leak down tester, I put a compressed air nozzle with a rubber seal in the plug hole at TDC. The air was easily exiting out of the oil fill hole in the VC. When I covered the VC the air came out the PVC breather. It was then I fully realized I was screwed. I'm not sure why the compressed air comes out of the VC at TDC so easily. All I can figure is the head gasket has a breach to the oil orifice. That, and I feel pretty certain #1 piston is screwed. Perhaps there was a preexisting weakness on the 120k mile org. block. The plan is to run this setup into the ground until winter. Maybe with one last 16 PSI huzzah to put it to bed proper. Then I'll tear it down and build back up with a p90 and forged pistons. I've searched around and found some info on forged pistons, but nothing conclusive. I'd gladly accept any suggestions on what to get for a low price. I'm hoping to use the 280 rods / p90 head / flat top pistions / and 8.0 to 8.3 compression. Everyone who gets a ride fears for their life. And I'm the only one who thinks it needs to be faster. Adam

I too was staving for fuel when I first resurrected my Z. Your poping is probably front firing in hte intake from going lean. I didn't start finding the problem until I put a fuel gauge under the hood and found I was running half pressure. This was after having the tank professionally cleaned and putting on a new fuel filter. So, what was the culprit? There is a screen in the inlet of the stock fuel pump that had collected a pile of rusty crap. I dug it out of there and my problems went away. I've been running that same original pump for the last 4 years. See if this applies to you.

wigenOut-S30, Here is some data on boost threshold for my setup: Flooring it at 2500 rpm 2500 = 4psi 2600 = 5psi 2700 = 6psi 2800 = 7.5psi 2900 = 8psi 3000 = 9psi 3100 = 10psi The wastegate was set to 10 psi. I think you would have to wait until 3500 rpm to see 15 psi. These numbers would probably improve with an EBC. The response between shifts is very quick if you're shifting where the next gear leaves you above 3500 (and I would think you would be when driving hard). The power builds in a nice linear fashion and lets me hammer each gear after 1st without cooking the tires too bad. More is better, but this is nice currently since I'm operating inside of what the tires can handle (215/60/14). The Mega Log Viewer lets you put in your drive train ratios to display MPH. I logged a full effort blast through the gears and found the following: 0-60 mph = ~5 sec. (the tail end of second gear) 0-100 mph = ~ 12 sec. (the beginning of fourth) I'd like to see those times lower and I think there is a little more to squeeze out of this setup yet.

Shhhh, don't talk like that, you'll get TonyD on you about boost threshold. I looked through my logs and couldn't find anywhere that I was trying to boost much below 3000. It takes ~1.5 sec to reach 12 psi from 3000 rpm vacuum based on current logs. From memory, I don't think I get more than 7psi too much below 3000. However, after about 3k it's like a runaway freight train right up to the rev limiter. I'm curious now for logs on the low end. I'll stand on 5th at 2500 rpm and see what I get.

Thanks Prox. Last night I felt pretty fast. There is a 4 lane road near me with a 6% grade that lasts for about 3/4 mile. I was pulling out at the bottom of the hill from a side road. Before I was even half way up the hill I was passing the last car that had come by at a 100 mph. The Z was going as fast up that hill as it does on a flat. Wee

Thanks for the kind words. gearheadstik: those are 450cc DSM injectors, now I realize that wasn't mentioned anywhere else. cygnusx1: we're going to have to do some information sharing on MSII tuning I'm going to try and share any insights I learn along the way that go against traditional Z thought. Like how I can be pig rich (if I so choose) at 6k and 10 psi with the old stock fuel pump. I have a better one but haven't needed it yet.

Just a little thread to announce the success and pseudo completion of my turbo conversion. I couldn't have done it without this site, thanks to those who run it. I have added a Holset HY35 to my stock N42 L28, gritty details can be seen here - NA to HY35 build diary I can highly recommend this turbo, it seems like a perfect match to the l28. BigPhil, you were definitely my inspiration, though I hope to keep mine together longer . I'm currently running 10PSI and that coupled with 8.3 CR and the HY35's efficiency leaves me well pleased. I have more tuning to do but the thing is impressive already. I can't wait to get some sort of benchmark. So far I only have the logs to go by. They show that stomping 3rd at 50mph turns into 90mph in 4 seconds. Here is a run down of what came together in this build: Stock N42 block/N47 head 2003 Holset HY35W 6"x18"x3" vertical intercooler 3" mandrel turbo back exhaust Megasquirt2 with EDIS ignition 450cc DSM injectors LC1 wideband I'll post some kill stories and such as things go on.
