Brad-ManQ45

if it can idle properly, then it is definitely not the injectors causing the problem - it is as I suspected - not enough resolution or the tuner ain't gettin' the 300ZXT maps/settings right. I personally wouldn't even fool with the mass air conversion with the 300 zxt stuff. It's gonna be MS for me!

Saw that last night before I created this thread. I think his problem is the ECU not having enough resolution (300zxt). He hasn't stated what his A/R is at idle. Large iknjectors for the cylinder size present a problem, not only at idle, but off idle as well. If the ECU doesn't have enough resolution, you have problems. What I am trying to determine is at what size does idle become a problem maintaining a 14.7 a/f ratio, and does the injector type have an affect. Once again, from what I've read, the disc type injector is supposed to be the quickest in terms of opening/closing, so I am looking for empiracle evidence to support this. I didn't want to put this in the MS forum, although the MS Extra Hi-res code and MSII should have the resolution to provide a valid platform for such a test.

I'm putting this question in this forum, because I don't think it belongs in the Fuel Delivery forum. I am asking if anyone has experience with the 2 or more of the 3 basic injector types in a high hp/displacement turbo'dengine. From what I have been able to gather, the disk type injector seems to be inclined toward opening/closing faster, therefore making them what would appear to be the injector type of choice for small displacement high boost engines. I am assuming the fuel injecton system has enough resolution to make use of them in order to provide a good idle (not rich). Has anyone tried 550cc injectors of the disk type (Rochester/Lucas) and one of the other pintle or ball type injectors that can share their experience? Thanks

Nice Phil... Maybe after I get a few restaurants opened up I can start work on stripping and painting my '83ZXT, then I will MS and convert to an overdrive automatic... I DID buy a welder and compressor, an dtook welding classes - that was because of my '75 project car though - it needs floorpans and subchassis connectors and patch panels. The '83 needs a couple of rust throughs fixed on the body and battery tray firewall work. Since it will be my daily driver, I'm gonna learn on it first.

ScottiGNZ has already proven that the base of the windshield is higher pressure - he had to close the baqck side of his hood scoop off in order to get his car to cool properly of course, this was an RX7. Datsun also had that (IMO ugly) hood for the Z with the opening ON THE SIDE of the scoop.

How about an early GTV? Always been partial to 'em...

Coat both inside and outside.

After I have used either flapper disk or a roloc disk to clean, I go over the metal with acetone, then spray OSPHO on the metal.

Man, it could be really easy to hate some of you guys - if I could ever get past the jealousy stage!

I bought a Jet Bandsaw for my plate cutting.

I think it would be interesting to dyno an engine that has been set up to run both methanol injection and water injection to see what the differences are. Basic assumptions: At a particular boost level - let's say 20 psi, maximize timing, fuel, and both water and meth, then see what the power and torque curves look like. Reason for wanting to know: I believe that water injection will provide more torque, due to the expansion of the vapor. I believe that water will also keep the valves and combustion chamber cleaner. Please Note: These are just beliefs with no foundation, but would like to have them either proven or disproven.

You might want to do a search for SiliconeBoy's TTLT1 setup...

I wish - but I doubt it could even fly in California.

JTR mounts put the engine too far back in the ZX - you really only need spacer plates.

Unless you are using good quality housings (think Cibie or Hella), I doubt you'll ever be satisfied with H4's. Of course I am talking E code headlights here. I have had Cibie on all cars that had 4x6, 7, 5.25 or 200mm lights on them and have always been impressed with thir control of the light pattern, unlike what cars come with nowadays (non HID).

If you were going to do that, think about an air/water system. That will get the core doing the air cooling as close as possible to the turbo/TB are. You could then use evaporator coils to cool either the radiator portion OR the intercooler portion or both, and possibly utilize other methods to cool also - like NOx, CO2 or dry ice. You would have the ability of having a second radiator to use for the dry ice mounted wherever.

Good news! thanks for the writeup - i think this should be a sticky under FAQs...

I would get some contact cleaner and clean all the contacts for the FI system. When cleaning the contacts at the computer, unplug and replug 5 or 6 times.

Welcome aboard! Awsome cars. Really hope you can make SEZ in March!

I have a Ruger Redhawk .44 Mag that I used to go javalina (pig) hunting with in Texas. I also have a Witness 10mm that I wouldn't hesitate to use - but not at 100 yards - the barrel is just a bit short. Handloads for either scenario. Funny thing about the 10mm Witness, even with hot loads, I can shoot it better than my .45 Witness.

She looks like she's into heavy metal...

Sounds like my Q45. I have no doubt that SAABs were born from Jets - the jets that precede turds. Any way you look at 'em they stink.

ZX gas tank=19.8 gal, LS2=~16 In tank fuel pump = more hassle to replace, and if you aren't aware of it, you shouldn't run the tank below 1/4 full in order to provide enough cooling for the in tank pump (warm climate). This is one of the neat ways that manufacturers use to help dealerships make money on sevice - they don't make much selling cars... Personally, I would use your stock tank, and modify it for bigger fuel lines if necessary, and use a bigger external pump. Let's see now, more capacity, less/easier fab, easier maintenance. Sounds like the ZX tank wins to me...

Caused a few drib - I mean drizzles here too...

I've always liked the Opel GT and the Manta. My brother had a Manta (75) until he totalled it. I think it's a great idea to get one back on the road!
