rossman Posted April 3, 2014 Author Share Posted April 3, 2014 Ok, so here it is spring time and the dash is still sitting in my dining room! I finally managed to figure out that the FSM wiring diagram and my car's hand brake wire does not match. Finishing up the dash seems simple enough but now I have other interests that are consuming my limited time Quote Link to comment Share on other sites More sharing options...
rossman Posted September 16, 2014 Author Share Posted September 16, 2014 (edited) Axles finally complete, Dash is in, wiring is a mess! My house is for sale and is supposed to close mid-October. I would love to drive the car to my new apartment rather than have it towed. I need to get the car again running soon! Missing a few straps but you get the idea... I'm trying to figure out where all these bullet and spade connectors go: Edited September 16, 2014 by rossman Quote Link to comment Share on other sites More sharing options...
rossman Posted October 5, 2014 Author Share Posted October 5, 2014 I drove the car for the first time in two years this morning. Its hard to believe it's been that long! I'm moving so I'm under the gun to get it going to avoid having it towed. Its very rough but good enough to drive it the mile or so to my new place. It was kinda funny, as soon as I pulled out of my steep ass driveway it died, restarted but barely ran, died and would not start again. The wideband was showing super lean. I was like WTF???? I could not for the life of me figure what changed in that instant. Did something fall off? Did the drivetrain or suspension pull off a low hanging wire? What the heck could it be? Maybe it ran out of gas? Naw that can't be it. I put 5 gallons in it....maybe I'll put some more in just in case. Fired right up. Sometimes it's the simple things.

rossman Posted October 25, 2014 Author Share Posted October 25, 2014 (edited) I got the car registered and inspected today. The inspector guy was highly annoyed because he couldnt figure out the clutch. He even called it a pos under his breath. What a jerk! Anyway, I got my sticker .The car feels VERY fast and I only have a 5 lbs spring in the wastegate, no boost controller. Baby steps.

rossman Posted December 5, 2014 Author Share Posted December 5, 2014 (edited) Well, I think I may have trashed my differential. It was the first time I held it to the floor all the way to redline (7500) 1st, 2nd, 3rd, 4th...>60mph then let off due to major pucker factor . I coasted down to <60 mph then hit the gas to maintain speed and heard a howling sound from the rear of the car. I drained the differential when I got home and found LOTS of shavings on the magnet . Gonna pull the diffential tomorrow to see what's going on. Oh, well, I needed a higher ratio anyway . I'm thinking 3.51...any other options that fit a z31 LSD?

texis30O Posted December 5, 2014 Share Posted December 5, 2014 Do the Ford 8.8 swap. wfrittz is making a kit. I am using it. I should be on the road by the end of the month. Quote Link to comment Share on other sites More sharing options...
RJ280ZX Posted December 5, 2014 Share Posted December 5, 2014 Z32 or Q45 diff swap is what I recommend Quote Link to comment Share on other sites More sharing options...
rossman Posted December 30, 2014 Author Share Posted December 30, 2014 (edited) I am hoping to keep the current setup. The 8.8 swap sounds awesome but it's more money/effort than I want to spend right now. I pulled the differential and inspected. The bearings are trashed but the gearset looks good. Ther is scoring and heat damage. The guy who assembled it put a TON of shim on the side bearings. Maybe he shimmed it too tight? I dunno. There is also a bunch of metal shavings inside which I assume contributed or caused to the bearing failure. I need to find the source of the shavings. I did drive it for ~100 miles with considerable clutch chatter. Clutches are coming out this weekend for inspection.

texis30O Posted December 31, 2014 Share Posted December 31, 2014 Well I would take it back to the guy who put it together and make him make it right. I have a little over 1k in my diff, not counting the kit. FYI. It is worth it though. I have a little more horsepower than you do I think.....

rossman Posted December 31, 2014 Author Share Posted December 31, 2014 (edited) I don't believe my issues are caused by the differential being too weak. It should last a long time if I can get the differential in order. I haven't seen any guys with relatively small displacement turbo engines (e.g. big phil) run into problems with the R200. Also, I don't have any plans to upgrade power-wise past the currrent setup. Frankly, I have lost interest in high-horsepower cars and I have another expensive addiction (cycling) that is more satisfying to me. Besides, the speed and power of this car scares the sh!t out of me even at it's current, poorly tuned 10 lbs of boost state! It's been over 3 years since the differential was rebuilt and I don't trust the guy to do it again. I'm going to let him know what happened and move on...assuming his assembly was the issue. Here is what's going thru my mind...I take the guy a factory set-up differential, have him swap out bearings and seals and he has to install almost 2X the amount of shims. My money is on an incorrect setup. Edited December 31, 2014 by rossman Quote Link to comment Share on other sites More sharing options...
texis30O Posted December 31, 2014 Share Posted December 31, 2014 I know you are in Seabrook ( BFE...LOL) The guy who did my set up is in Tomball ( The other side of the world from you) If you need contact info let me know. Quote Link to comment Share on other sites More sharing options...
rossman Posted December 31, 2014 Author Share Posted December 31, 2014 BFE is relative! Does your guy have experience setting up R200's? Driving to Tomball is cheaper than shipping this beast cross-country! Quote Link to comment Share on other sites More sharing options...
RJ280ZX Posted December 31, 2014 Share Posted December 31, 2014 Too bad you are not closer, I could do it for you. If you need some parts let me know, I usually get really good deals.

texis30O Posted December 31, 2014 Share Posted December 31, 2014 PowerFab is my shop I use. they have done all the swap work on my 240 and have worked on my Supra. Good guys. Dane and them are right behind them. I used Jeremy's Drivetrain guy for my set up. PM me if you want his contact info. Quote Link to comment Share on other sites More sharing options...
rossman Posted December 31, 2014 Author Share Posted December 31, 2014 I've used PowerFab before. Jeremy is a good guy. They recommend I take the differential to Houston Automatic Transmissions. Scott at HAT told me that if the bearings are shot there is a good chance the gearset is shot. I'll probably run it by there Friday for an estimate.

74Adam Posted February 6, 2015 Share Posted February 6, 2015 Hey Ross, how did you mount those Blue Sea bus bars on the firewall? Quote Link to comment Share on other sites More sharing options...
rossman Posted February 6, 2015 Author Share Posted February 6, 2015 I mounted the bus bars with sheet metal screws painted with rust preventative primer. I wet install all sheet metal screws to prevent rust. My differential is at Houston Automatic Transmission awaiting back-ordered parts. Scott is a good guy. I have confidence he will do the job right. Quote Link to comment Share on other sites More sharing options...
texis30O Posted February 6, 2015 Share Posted February 6, 2015 lol he is. Mine is still together. but I am going to beat on it this weekend just to make sure...... Quote Link to comment Share on other sites More sharing options...
rossman Posted April 13, 2015 Author Share Posted April 13, 2015 The differential is in and the car is back in action! I've been breaking in the gear set over the past week, trying to stay out of the throttle. Man it's hard; the car wants to go like a bat outta hell! There are a few issues to work out: 1) The tune needs lots of work. My AFR's jump around a lot, even at some crusing speeds. Just need to spend some qualty time with it. 2) I'm getting a lot of buzzing after it warms up at the fuel filter mount on my firewall. It only happens when the car is warmed up at idle. The filter is clean. Not sure what's going on. It may be that the A1000 pump is just too choked off at idle. I have 5/8" feed and 1/2" return lines so you wouldn't think that is the case. I do have a pump speed controller which isn't set up yet, right now it runs full speed all the time. It should should help as it will reduce the pump speed by up to 50% at idle, thus lowering the fuel pressure and stress on the pump. It also means I have to re-map the ECU but that *should* be pretty straight forward. Quote Link to comment Share on other sites More sharing options...
