Brad-ManQ45

Thanks 1seymour! I will be eventually installing MS in my '83ZXT, allthough I am thinking about EDIS for ignition... Please keep us informed about your experience and especially tuning. You might want to post what other mods you have done to your ZXT... Brad

Sure they're not 3/8"?

Have to agree w/Grumpyvette here. ScottyGNZ had Hypereutectics in his GNZ and blew a head gasket without having any problems from the pistons - the key of course being to AVOID DETONATION. IMHO, you mightg as well get forged and have peace of mind/fudge factor when dynoing and tuning on the road.

Assuming the same amount of overall flow for TT vs single T, the biggerr turbo's diameter has to increase a pretty good amount - ~1/2 to 2/3's bigger for the same amount of flow. The increased diameter causes rotational intertia to go up not by a straight factor, but exponentially. Hugh MacInnes covers this in his book on turbocharging. Road racing a V engine, he suggests using two turbos for quicker spool. Drag engines want to keep the turbo going as fast as possible between shifts, so the use of one BIG mamma-jamma is the norm (think like the latest TT Supras going to one big one)).

and musicians...

Depends on what type of wastegate you use...

The purpose of sectioning the strut tube is to allow the use of a shorter strut in the tube in order to gain suspension travel lost when using shorter/stiffer springs. If you use springs that lower the car 2", then you have lost compression travel when using the stock struts - you have moved the position of the piston in the strut downward 2". Since the Z only has a limited amount of traqvel to begin with, you haqve to have really stiff springs in order not to bottom out, which compromises ride qand handling in bumpy corners. You can use a lighter spring, have more compression travel, hold larger bumps better and ride better with the sectioned struts and shorter inserts.

I will chime in and say that for most HybridZ-ers, MIG is more forgiving and easier to learn for what we are going to be doing, sheetmetal and schassis work. If you start adding thin aluminum into the equation, then TIC starts looking good. MIG was developed for the mass production auto industry for body panels. Foir people just starting out, MIG is a great way to get into welding. I took classes, and I too bought a MM175 - this is one fine machine. I learned on LIncolns in class, but I have heard some bad stories about CS at RED that mad me pick BLUE, and I'm glad I did. I have finished my rotisserie and am awaiting time and funds for hoisting the beast up and attacking floorpans and subchassis connectors - soome warmer weather wouldn't hurt either.... I will back everyone else who has said to go with a quality product. Even professionals have a hard time with the cheap crap. For the real beginners worried about burn through on sheet metal, Harris makes a product called "Twenty Guage" that is actually .031", and is a cored wired that you use gas with. VERY difficult to burn through with it - you really have to be trying. As far as weld quality goes, MIG and TIG can meet the same standards, but it is a little harder with MIG - you simply can't see it as well because of the gun tip. I have produced some absolutely beautiful welds (mostly when practicing, of course!) - That stack of dimes can happen with MIG just as it does with TIG, but it requires a lot of experience and practice. I happen to be fortunate because Warren lives about 8 miles from me and has a TIG, we just tore out his rear suspension arms to put iin camber and toe adjusters on his 280ZXT....Possible to do without removing rear suspension member if you have a right angle dril l- heh heh!

I'd say that on a stocl 280ZX you're better off with the turbo in the stock location because there are hood vents to get heat out when idling. On a 1st gen, I wouldn't think there would be any difference, except for weight distribution...

Congrats.

I just saw that a post from another thread got here - strange....

Congratulations!

Warren whould be able to aid you....

But won't be quite as efficient....

Sweet! SB - you have accomplished more in the time that you've been working on it than I have, but then I'm so anal, I plan everything to the last detail, then come up with a better idea, and have to start over....

You might want to elaqborate on the build level of the 302 in order to match tranny's properly. ne of the early F-car T56's might be a better match than a later one, if you don't go T5...

It doesn't matter how much goop, pumice, acetone, brake cleaner I use, I still leave smudges on the white refrigerator My wife grumbles when I come in to get something to drink, and grumbles if I ask her to get me something to drink. ( substitute Bitc*hes for grumbles) I CAN'T WIN! To be fair, there WAS a period when building the rotisserie that there were a LOT of metal shavings tracked in, and black handprints, BUT THAT WAS TWO YEARS AGO. They NEVER forget...

Oh yeah....

Looking at that reminds me of why my wife no longer allows me to put her bra on for her....

Brother had one 'til he totalled it. Nice car. I remember an article about one with a Boss 302 engine in it. This was a nice car at the time - the engine was a bit doggy though...

can't use any extra code, MS2 is C whereas MSI is assembly...

Wish I could fit in one of those.....

I have pretty much had a manual transmission vehicle in the stable since starting to drive in 1970. After bbeing run over by a Lincoln Town Car running a red light on my motorcyle in '75 (leg and ankle) and having an idiot in a 2/4 ton truck towing a 25 foot boat rear-end me in a Starion in '86 (lower back & hip), I find I am simply not able to drive 45 minutes in stop and go traffic with the clutch on my '83 ZXT. Yes, it is fun to take out for a spin, but in the Atlanta area, everywhere you go is a traffic jam. I have had the ZXT since '91, and for 9 years it was basic transportation, but that was always against the flow of commuter traffic (sometimes 35 miles one way). When I moved further out and got a dose of driving it (15 miles each way, no interstate) everyday in our traffic like everyone else, I started driving the Q45 which I had bought as an "our car" for when we were both together on weekends and on trips (the ZXT and her Stanza both manuals and rather noisy on the interstates). When I get around to freshening the ZXT, I am seriously considering adapting a 200R4 or 4L60e to it and driving it more. The Flowfit seats are comfortable all day, more so than the Q's or the Lincoln Town Car seats. The Q is now my wfe's car and the Town Car is what I drive (got rid of the POS Stanza and bought her the Town Car, but she doesn't drive much, and between the miles and the cost of premium.....). I will say the that Lincoln sedats a far more comfortable than the Q45's though. The real reason autos are so popular is that they leave a hand free to apply makeup, hold cell phones and lattes and flip people off....

Stock tires on the turbos were 205/60/15...

So we have curious and curiouser....
