I am trying to fabricate a dual exhaust system on my 240. My knowledge of exhaust assembly is limited and i want to order piping to put together my system. In what circumstances would a person use a flex pipe like this. Is it meant to allow for twisting of the engine.Does anyone know where to find a X crossover pipe in 2". I have found 2.25"(inlet) but don't know if I can make that work with 2" pipe(O.D.)

I just finished installing a BW 5-speed in my 71. I thought I would post this short cut to my thread from CZCC so it would be available for search results. It may have some useful info for folks as far as modifying the crossmember with lots of pics. http://www.classiczcars.com/forums/showthread.php?t=25178

I am using a r200 moustache bar. The FAQ says to flip around the front mount. I can't remember what the original positon was. I know that when I flip it one way the mount is off by a couple of inches, the other way it is off by a bolt hole. There is only one r200 moustache bar isn't there?

I am installing a r200 in my 71 . In order for the diff to line up with front diff mount I have to pry the diff back about an 1/2". Is this correct? When I do the search I can not seem to come up with a definitive answer. In Carl Becks r200 swap page he talks about two different mounts, but MSA shows one part# for all Z's thru 78. I have made a Ron Tyler mount based on the stock mounting point of the original mount since I am still running the L6. So was I correct in ASSUMING(I hate that word) that this small change in the postion of the diff will not effect anything?

I am mating a bwt-5 trans to a P-30 engine and I am using the Turbo flywheel that came with the trans. I noticed the torque values for the flywheels are different for different year cars. Are the torque values mated with the crank or the flywheel. The p-30 has 101 ftlbs values while the ZXT shows 80lbs,which one do I use??

I get to drive the one of the biggest, most powerful machines on the earth. I usually have the throttle of 10,000 to 15,000HP and 250,000lbs of torque traveling 60mph. The best part is i get to blow the horn:biggrin: Class1 locomotive engineer

Beautiful engine bays guys, but how do you go about hiding the wire harnesses. I would like some ideas and direction for doing this to my car? Also the brake lines, where are you running them?

I guess I was going off of memory instead of a tape measure. I'll look at it again.

I guess I will build the mount on the car with the stock mount installed and tack it together. This way I am assured to keep it in the stock position. I am guessing that adjustment is done by spacing the polymount with washers?? I didn't quite figure this out by the posts.

3.54 might be your best bet and there are alot of them around. Like I said I think the "long time getting thru gears" is the nature of the beast with a bwt5 trans because it was set up for a turbo motor. If you go to turbo or stroker that has more low end then the 2.4 the car will excelerate much better .Don't forget to check the driveshaft yoke set -up before swapping diffs. The driveshaft is special for the bwt5 so parts are swapped somewhere!!

I guess I don't understand your answer WIGEN-OUT. It seems the pics I've seen with this mount installed show the front of the diff significantly lower or maybe they were adjusted lower with the mount? Are you telling me that the original mount is left in place and this mount sandwichs the diff?

If you look at the individual gears in the bwt5 trans 1st and 2nd gears are pretty low . The way I figured it ,running 3.54 gears coupled with the bwt5 is= 3.90 gears with a late model nissan 5 speed. The problem is the ratio spread between gears when you start shifting 3rd ,4th. If you put 3.90 gears with the bwt5 trans it would be a rocket thru 1&2 anyway.IF you go with a r200 diff you will have more options . Are you sure you have a bwt5 trans with a r180 rear?

I was considering doing this mount for a Z but I will have the original 2.4 and a r200 rear. My question is do I need to make an adjustment for stock driveline angles? From what I read this mount lowers the angle for v8 conversion.Has anyone used this with the l6 configuration . I am rounding up materials today so any help would be great.

sounds like you have the original 3.36 rear which would be way high for that set up.You 'll need at minimum a 3.54 or 3.7 with that trans. Guys have told me that the bwt-5 trans is not very good for the n/a motor. I would definitely try some lower gears and see how you like the 2.4 ;then you might decide it's pretty quick after all !

Jernut, nice car! Just curious how you like your BWT-5 trans . I am going with the same set-up with the 3.54 diff and I am anxious to see how it performs with a N/A engine. I am figuring the first 2 gears will run pretty quick but not sure about the other gears with the bwt-5 ratio spread. Can you let us know how it drives on the highway? How's the overdrive rpms, and how much downshifting to get in a good powerband? There is a lot of folks who say that trans won't work well with a n/a engine, what do you think? are you running the stock shifter? Sorry for so many ????? but that set up is a little unique:)

I've been trying to search for ideas on hiding the engine wiring harness but I am not finding much. Maybe i am not using the right phrasing in the search but can anyone help me. I am considering hiding or rerouting the wire harness altogether to clean things up. Might consider rerouting brake lines too!!
