sounds cool!

Blow through huh? I thought about doing that as well. I ended up finding a AEM ecu and am gonna run a map sensor instead. Just out of curiosity, how do you like that setup? Any issues? I was thinking that you could not use the factory PCV setup and would have to get a catch can.

What kind of fuel management are you using? do you have afm or maf style sensor? If you do, it is preferable to have a "bypass" valve and not a "blowoff" Something that can vent the released air back into the air intake so it does not confuse the air flow sensor. If you just realease the air, you will get a very rich condition causing black smoke or even flammage out your exhaust pipe between gear shifts.. LOL

If you are planning on going fuel injected/turbo... grab the turbocharger, ecu, and maf sensor.

I mounted my AFM in front of the rad like you are suggesting. Just lengthen the wires and mount it sideways. This way you can have your filter up front for cooler air as well. Funny how I did mine, I really lucked out. My buddy had a n/a 85 300zx parts car. I noticed the plastic air intake was 3" and just about the right dimensions/shape to make a cold air intake on my 76turbo Z! It worked like a charm.. just used the stock rubber boot from the turbo, into the 300zx air intake, then the AFM then the filter. If you can't find that piece, you can also use some 3" mandrel bent pipe.

I was going to buy a diff out of a 87/88turbo z31 once. I would have had to remove it myself in some poor conditions so I decided to confirm that the car indeed had a LSD before I would bother going to all of that work. I Got the serial number from the car and went to the dealership to see if they could verify anything for me. After spending a few minutes on the computer the parts manager told me that this car was a fully loaded model with every bell and whistle. However there was no evidence that it had anything special about the diff. In fact he told me that he could find that there was no evidence that there was anything special about ANY diff in ANY z31. I did not bother to remove the diff and kinda assumed that there was difference between Canadian and US models.

Seeing it as the fittings for a oil cooler are already there I would take advantage of it and use it. You should be able to get Metric to SAE hose adapters at a good hydraulics shop. Then just ask them for some "push on" hose ends. Make up your own custom lines and run a oil cooler. You could even run the hoses in a closed loop for the time being if you want to hold out on getting a cooler. If you do want to remove the system altogether, I think there is a hex that you can get a wrench onto at the base of the threaded shaft the oil filter screws on to. Of course you will need the parts from your old block to replace them with.

I haven't gotten to doing mine yet, but I am planning on using a 3.5 inch downpipe. I think I will get a ring machined with a 3.5 ID and a 4.0 OD (or whatever that turbo actually is) with a bevelled edge to match that of the turbo Vband. I figure if I gotta make one, I might as well make several and sell them. However this wont see the light of day until at least April.

Back in 99 I got a phone call from a buddy that knows I'm into Z's. He asks if I am interested in buying one, before I say a word I hear the guy in the background saying.. "tell him it's got new brakes and clutch and yada yada..." I laugh and say.. yeah, ask him how the frame is.. I hear "it's mint" Yeah right it is I think to myself, not in this part of the country. Anyway we are all out one day and decide to go take a look at it just for kicks. Damn, sure enough the undercarriage is in very good shape, quite a find. Still in need of some body work however and it does not run, interior full of misc. parts and junk. So I say to the kid who owns it.. well you got a decent project car here, but unfortunatly I'm not really interested as I already have a 280zx project. He only wanted $600 for it but I also told him he would have to find the right buyer as it is a bit of a basket case needing who knows what to be able to pass a safety inpection to get the car registered for the road. I wished him luck and said have a nice day.. I got a call a couple weeks later from him.. he asked me if I would by it. I said no, not interested. Then he says, look I don't have money for rent and I really need cash, if I gave it to you for $300 would you take it? I was like.. ?? for $300... yeah I suppose I would. Brought the car home and found the car was in actually alot better shape then I had ever guessed. The interior was actually really good, it had brand new brake parts for the car still in the package, under all the junk. I replaced the fuel pump and the engine ran good. Bought a couple of new fenders from Victoria and the rocker repaired and painted her up.

A Vg30 ecu would need the ignition to run the fuel injection because it needs a rpm signal. However I dont see why it would NEED the injection to run the ignition. I would just hook up a custom miniature harness to the dizzy, ecu and ignition switch. I'm sure it would work. Worst case senario is you MIGHT need a signal coming from the MAF to show you have air flow, well you could plumb that into your carb'd air intake.. LOL If you were running a electric fuel pump I would get the ecu to control the relay as well. I have seen pics of those 510's with Ford carbs on them. I don't see how it would be much lower than a FI intake manifold, especially with a air filter on top. There are also a few different kinds of upper manifolds that will fit, Pathfinder, Maxima, 200sx, Quest, Mercury Villager... maybe one of those would suit your needs?

I am gonna try one of these... http://www.bullyclutch.com/indexen.html I've heard good things about them. I know a guy with a L28et that bought one, he hasn't pushed the HP that far yet, but it has a very nice feel, lighter than stock actually...

Yeah, I don't see the point of twin turbo's unless it is a V engine. Unless you are looking for some sort of bling factor. I've also heard the old one about two smaller turbos spooling faster than one big one... Well that simply is not so as you would only be feeding it with half of your engine. It's just a more complex, cramped engine bay with double the amount of plumbing needed.

You have all that NOW? Does that mean at one time you were trying to fire it with just the coil and no trigger? I wouldn't think the driver in the ecu would like a load like that... it might damage it. Sorry if I am jumping to conclusions but without more info I don't really know what to say..

According to the Jim Wolfe site: http://jimwolftechnology.com/wolfpdf/ECU-ID.PDF You have yourself a 1981 ecu. I still have my old 83zxt ecu around, PM me if you are interested.

You didn't mention anything about the coil trigger unit. (it's the little transistor mounted right beside/with the the factory turbo coil. Two wires to to that trigger unit. From there it powers the coil. If you removed the complete unit from the donor car you shouldn't have to mess with the actual coil terminals at all. The coil trigger requires two connections.. 1. 12V+ switched ignition source. Usually Black/white 2. Signal from ecu Yellow/white

Anybody running one on a L28? Or am I gonna be the first?

That style distributor runs totally independant of the efi system, so yeah no worries.

I ran a dsm blow off valve like that one with no issues at 18psi. One thing I had to do however is get a peice of rubber hose (very small diameter rad hose actually) and connect the outlet to the air intake between the maf/afm and the turbo. Otherwise it would not run right, it would suck in a minor amount of air and mess with the afr's. Of course I don't know what setup you are running, if you have a map style sensor it is not a issue. If you do have a maf or afm, I would go with the dsm bov for sure...

it's a 87 pathfinder with a 84 Vg30et engine. Upper plenum has been swapped for a 90+ multi port Pathy plenum. No mount pics but it's stock (it was originally a VG) I had to drill and tap a extra bolt hole on the turbo block. No big deal though. The crossover runs under the tranny, alot of work to make everything fit. The crossover and DP are like a slippery snake.

I am surprised that you never found mine... click on the link for pics.. http://members.shaw.ca/icecube/PathyPipes/

I recently did some IC piping on my Z, I was really happy at the simplicity of the setup. I just got the cooler so I haven't had time to work on that. Here are some pics tho... http://members.shaw.ca/icecube/Zpipes/ I'm gonna be running a vertical flow IC

JSM, I can explain it to you, but I really don't feel like typing in a essay. Do you still have my number? Just give me a call. I will send you a PM with my # in case you don't have it anymore

The turbo flywheel uses a larger diameter clutch disk. The same flywheel can also be found on any 2+2zx (or a early Vg30 so I have heard) I was running 9psi on a stock small diameter clutch, but when I got my ecu chipped I fried it like a greasy egg. The larger clutch is much, much better.

You could always throw on this bodykit... http://www.thezstore.com/page/TZS/PROD/7AP/50-1504G

Use a ohm-meter to test for continuity when the throttle is opened. Basically it should read 0 or (out of limits) at idle, and give a reading when the throttle is like... 100rpm above idle.
