Here's a couple of pictures of my progress so far. Im sure most of you know of the brakes so I wont post pics of that. I also have a Borg-warner T-5 from a 1983 turbu Z, a limited slip h-190 rear end, 1" front and 3/4" rear Addco swaybars, and panhard bar.

AS with most things on your truck, I am guessing the BW t-5 wasn't a direct bolt up? What kind of driving do you do with that set up? Seems a bit overkill for normal everyday driving. I really impressed with the setup. What has been the hardest part so far? You should make a short video demo of how it handles.

Im really just wondering why with all that you have invested to make the truck stop/go/turn do you still have those leaf springs. Leaf springs, IMO, should have never been installed on anything. Worst form of suspension (but cheapest in the manufacturers POV). Any plans to 4 link it????????? A parallel or triangulated 4 link with coilovers would do wonders to how the truck rides and handles.

Leaf springs have their place...They also have more load capacity than any other setup out there and with the panhard it probably handles as well as any 4-link. |

Sure load capacity is the one reason to keep the leafs. But a leaf setup will never handle as well at a link setup. And if you want to call it a 5-link, you might as well call it a 6 link too (parallel 4 link with a watts link). Leafs doubled over on themselves are not only not safe (they were never designed to be like that), but ugly, and leads to poor handling characteristics (alters spring rates). Just my 2 pennys. Truck looks good, cant wait to see it finished up! Dwight Fahrenthold

I like the agressive look your 620 has. The spark plug route is different which is kool & im diggin the gauges you installed. Is that an oil cooler behind the valance?

I agree! Love the stance and the look.
h190 limited slip??? Where'd you manage to get that? Air/fuel gauge? Hooked up yet? Which O2 sensor did you use? |

LSD he probably got from NISMO for $900 back when they were available. T5 bolts up to an L20b. Bellhousings are not even the same design as the Nissan units. Its the driveshaft that needs mods. That is all. Good looking truck. Thanks for posting pics. Get a front bumper on there; I think that would clean it up a lot. |

Thanks for all the compliments. Your right Bleach the T-5 bolts right up but the rear mount and driveshafl do pose a problem. Powertrain industries sells a yoke which presses right onto the truck driveline....problem solved. All I had to do was fab the rear mount to accomodate the stock t-5 mount. Other than that I love it. I rebuilt it for $75 using a ford non-w/c kit and I have a pro 5.0 short shifter. I also scored a 240mm lightened flywheel for $10 that im running. Mike. I did a post on the limited slip install a while back. http://www.nwde.org/extras/forum/forum_posts.asp?TID=3243&KW=lsd Its a precision gear power brute. It was $436 shipped and they are still available. I beat on it daily and hav not had a single problem. The AFR works although its only a narrow band so its really more of a suggestion than anything else. It came with an 0s sensor so all I had to do was weld in the bung. I have another innovative wide band thats going in with the megasquirt. Pac. coast. Yes its an oil cooler behind the valance. I got an earls plumbing sandwich adapter with -10an lines. It also gave me a -4an takeoff point for my turbo oil line when im ready. Aired out. I have looked into the 4 link idea but have had good luck with the leafs so far. Somewhere down the road I may cross that bridge but the rear with the panhard rod and swaybar work fine for now. The breather goes to a seperate breather tank with the internal baffles because on my old motor I had a breather directly into the valve cover and was getting a thin film of oil everywhere. The front headlight is removed for an intercooler. I cut the inner fender well and boxed that area so I can get cold air to it. The scoop on the hood is from a turbo 300zx and actually works. It is not going to be for an intake but rather cool the intake itself. I figure with a turbo sitting directly below it there will be a good amount of heat there which as you all know is bad. I have the turbo header and snail wrapped in fiberglass header wrap and I figure with the added airflow over the intake I might be able to get away with a few more pounds of boost. |

Is this what your turbo engine is going into?

Fineline, I'm gonna have apologize in advance for the hijack... Dwight Fahrenthold
Not sure why you brought up the Watts link either, as it’s just a better mousetrap (pan-hard bar). It locates the axle laterally and allows it to droop and compress without moving the axle from side to side like a pan-hard bar does.
There’s a lot more to setting up a linked suspension (1-link, 3-link, 4-link or whatever) than just attaching some bars to your frame and axle. Everything from the length of your bars, to their angle (horizontally as well as laterally), your wheelbase, tire size and more play a part in how your suspension performs. Some people are more interested in a well balanced, responsive, predictable suspension that puts the power to the ground than one that just goes up and down. Here’s a few link calculators for those that are interested… http://www.performancetrends.com/4link.htm These calculators are free… http://mysite.verizon.net/triaged/4linkcalcv15html/index.html http://mysite.verizon.net/triaged/files/3LinkV1.0bBETA.zip A really good discussion on linked suspensions if you can wade through the crap talking :P http://www.pirate4x4.com/forum/showthread.php?t=7503 BTW…Leaf springs are one of the first 4-links… …and I still say his leaves with the pan-hard bar handle as well as a 4-link and infinitley better than a poorly setup 4-link… Bleach… The only T5 I have access to was in a 300zx behind a V6…is it the same tranny? |

No. The bell housing is different and from what Ive read the input shaft is too long although this has yet to be proven.

Heres the post on it. I should be getting back into it shortly and hopefully have it up and running by summer. http://www.nwde.org/extras/forum/forum_posts.asp?TID=3622&PN=3 |

The only reason i said anything about your 5-link comment is because I have never ever heard anyone refer to the panhard as a link, but to each his own i guess. I am just wondering how many 4 links you have built and installed??? Do you speak from experience, or are you just all talk?????? Have you ever switched a leaf spring vehicle to a 4 link and driven it before and after??????? Ive installed probably about 60-70 for customers for multipule different applications (drag racing, scca racing, air suspension, street rods). When your talking about people want their suspensions to do more than go up and down, we build them to do that and much more. Dwight Fahrenthold
