Yes pictures would be great of where the main hoop and support bars are. Does anybody have any input on cutting the main hoop at an angle and mounting it to the rear fender well? The hoop is already made and goes out to the inside wall of the car. The inner fender well seems strong, curved in three dimensions. If I put the 6x6 mounting pad and weld the main hoop to it with a brace to the shelf would it be safe? I don't plan on having to use the roll bar as anything other frame brace but as everybody knows stuff happens. Don

I bought the Art Morrison 8pt bar kit, I think it is the same as the S&W. The question I have is, if you mount the hoop on the shelf it is along side of the seat back. In my car (71z) the cross bar would then go through the seat. I think it is ok to mount the upper braces to the shock towers but I would mount them to the top of the main hoop to keep it from bending foward or back at the time of needing it. The way I read the nhra rule book they want the upper loop between 3 and 5 inches above your helmeted head, not in front of it and no more than 6 inches behind it. In a Z car yea right. All I can figure is to mount it to the fender well, then the cross brace would be behind the seat and not contact the seat back. I havent thought about the side bars yet. I kind of thought I would need the hoop in first. So far the hoop is "sitting" in the car and the straight pieces just laying on the floor beside the car. If anyone could shed some light on this it would be a great help.

Yes I am very intrested also, I would like ones for the 240sx. newer, easer to find .... Let us know how it works out. DP

Well a Z32 is what I thought the rear housing came out of as I was told it came out of a 90 or newer. The housing is the shorter style when compared to the 83 turbo R200 that I have sitting on my bench. I also had a R230 and the housing had the same mounting points as the newer R200. The newer R200 was labled viscous LSD on the back cover and the cover is held on by 10mm bolts insted of the older R200's 8mm. The cover is finned on the lower part and the mustache bar mounts have a wider mounting than the older one. The viscous carrier is temparly mounted in the 83 housing just to see if it would fit. I would need to find ring gear bolt bushings to put it in and use it. I have the ring gear held in by two bolts just to see, and it seems to have the fit and feel as the open diff I took out. I took the R230 back as I could figure out a easy (cheap) fit in a 71. I could be wrong what the viscous diff came out of but I don't think so.

Someone please tell me if I am missing something in the above post. If Z32 R200 LSD 's are real common it could be a cheap way to get LSD. Gotta go the F1 race is going to start. Don

The Z32 is a viscous type rear diff. The carrier will fit into an older (Z31 and before ) R200 that uses 12mm ring gear bolts. The viscous carrier will need to use the axle stubs that came out of the z32 housing because they are diffrent lengths from the earler units. Now the question is how do the half shafts connect to the companion flanges. What I did is cut off the CV cup at the base before it curves up to form the cup. I then had it machined flat and what is left is is a perfect place (dia of 2 3/4 inches)to weld a 1/4 inch flat plate. Have it turned to cut the space for the raised locating ring on the half shaft. Line up the halfshaft and use a transfer punch to mark the bolt holes. After drilling the bolt holes you should be able to bolt up the U-joint half shafts. I haven't figured out CV's yet. My car is not running yet so I have not tested it yet, but it looks to work. Yea I get to go pick up my roll bar on Saterday.

Speaker you also might check on the pin of those rods. I know I am building a ford but I think this will be the same. My eagle H beam rods are for a floating pin and TRW does not make a piston with pin locks at least in my engine. I had to go with JE pistons. If those are the same type of rods, then as per what I was told they are heaver than the stock rods and the TRW pistons are heavy also. I don't know, I am just a ex pontiac fan building a ford (I can't belive it myself). [This message has been edited by Dp351zcar (edited March 22, 2001).]

I too will never go old. Never, never, never but reality does sometimes set in, like when I realize that it has been 21 years since I have had just a block and a whole bunch of boxes. It sucks being able to remember decades, late 70's a gto had my thoughts then 80's motorcycle roadracing, 90's wife house and kids. Now I'm 41 and I can't get my Z out of my mind. Well I guess some things don't change as I still want to build something to go fast.

My z goes 66,000 miles/second I think, and thats on jackstands as it travels through space on this world. I think it sometimes will be faster when I get the engine and suspension on.

MSA sells them. Or at least a stock replacement.

TFL I was in Kennewick today (Tuesday) working. I would like to have seen your z as I have not seen a modified z yet. Also I was wondering do in your area do the farmers always move their dirt fields by way of the air? By the time I had gotten to Prosser I had driven through walls of dirt moving through the air.

Terry's right, also all fords that I know of have the oil pump at the front of the engine. On the rear sump pans the oil pick up at the rear of the engine has a long tube that connects it to the pump.

I think that almost any engine (automotive engine) will fit in the z car. You just have to raise the engine up higher if is going to be a tighter fit before you trip the quick release on the hoist. Gravity will do the rest.

Differential plate? I do not know what that is. My quest for knowledge would be boring if I knew everything. Are you thinking of putting in a standard rear in, or keeping with IRS. If putting in a standard it would need to be narrowed and then it could be installed like someone in members cars (I think) has done. If you want to keep with IRS a magazine that could prove help full might be Street Rodder as street rodders are into any trick type of rear end that they can fit in there. A dana 60 would be a very heavy rear. What do you have that could blow those like that? Don [This message has been edited by Dp351zcar (edited March 10, 2001).]

I think a 302 is a better choice than a sbc as they lighter and a better package for a z. What you would look for is one with a rear sump oil pan. I think they came in the trucks and newer mustangs. What I am stumped on is how do I want to bolt the engine in? I want the rear most weight I can get. Do I extend the motor mounts forward to the stock mounts on the cross member or do I build up mounts where the ones on the block are. Then there is a front motor plate, but wouldn't it attach to the mount towers on the cross member and there by being the same as the extended motor mount? I don't know. Also I would like to have room for the headers I plan to make for it. Don

Track days at sir? When? I can hear cars sometimes when they run on the roadcoarse at sir. I would love to see a v8z out there (I have never seen a v8z at all) and see how it goes. I am a year away from my 351 z running I think. I am building it for open coarse events, autox and drag racing for fun.

I also would like to know the diffrences in roll bars between scca and nhra

In the nissan motors book the pt# for the 12mm carrier is 38420-RS660. The one listed for the s13 and the s14 is the same. I ordered a 38420-RS650 from MSA it is the same as part as nissan sells, in fact they ordered it from nissan motorsports and charged $120 less for it than nissan. Anyway it looks the same size as the newer z32 carrier and and older 280zx open carrier sitting on my bench with it. I have as I said a newer style LS and on the back cover it said it was a viscous type. I took carrier out and put the ring gear from the older (83) R200 on (with two bolts to hold it) and put it in the older housing. It seemed to fit just fine. I then put the newer companion flanges in (which I have modified for U joints) and it looked like it would bolt in my 71 Z. If you do use a new LS carrier in an old R200 housing you will need to use the companion flanges from the new carrier as they are not the same length as the old R200 shafts. Beware that the ring gear bolts on the z32 carriers are 12mm. [This message has been edited by Dp351zcar (edited February 03, 2001).]

Motorsport Auto has the same carriers for $120 less. The difference between carriers is 10mm and 12mm ring gear bolts.
