I'm hitting a rhythm so hopefully soon I will start the next phase of upgrades the the rx7. Finally getting my new shop in order. I now have a 30x60 shop with nice clean concrete, insulated, heated and plenty of lighting. Have 4 projects in it now with plenty of room to work on everything. Helping a friend with a Polaris ATV rebuild, watching one of my son's friends get a miata ready for spec racing, I'm working a stock rebuild of a 95 GMC Jimmy and then the rx7 is setting there waiting to be taken up a notch with suspension, body work and boost. Sold both of the rx8 cars so I can focus my efforts on the rx7. The Jimmy rebuild I to give me a cheap clean winter commuter. I was in a pretty bad car crash in July. Got rear ended by a distracted driver, never hit the brakes and hit us at like 45mph. We never had a warning. My wife may take up to a year to recover. Pretty crazy, but we are learning to enjoy what we have each day and keep overcoming obstacles. I have missed keeping up with everyone's projects. Blake is probably building some nicely thought out project and Zach Brown is prbably in the sevens by now.  :poke:

Sorry to hear about the crash Bryan, that sounds terrible;  glad a little good can come out of it.

And yes, I'm building a massively over-thought-out project, in fact.  Haha

My odyssey PC680 battery bit the dust. It lasted about 10 years using harbor freight float charger on it all the time. Picked up a new one and back running.

Updated my MS3 FW to 1.5.1, replaced wideband sensor and added a simple on/off air valve to help cold starts on e85. Here is a pic of the new garage. My wife got her C3 vette. Miata John and Mirage doing some brake upgrades. The jeep project was for a cousin, we put a steinjager long arm kit on it. Who put gas cans under the welding table,  :)

Ok, finally going to sort the 8.8 on this. I have had problems with the out bearings and the clutch LSD doesn't work that well unless you burn out and then hit it once to lock it up. I asked a shop for prices on installing the ford 9" outer bearings, changing the axles to support that and putting a T2 Torsen locker in there. Any advice going down this road? Oh, and I orderd a Ronin widebody kit. Spent all these years on engine and nothing on body.

Been a while since I caught up on the project Bryan.  Looks like you went through a rough couple of years so I'm excited Ronin gets to be part of some joy here really soon.

Joel, I'm looking forward to the Ronin parts. I pulled the airdam and crash bumper off today to start planning how to fit the FMIC and piping, oil cooler, trans cooler, large air filter hopefully in a cold air location. I will add some new steel up front to reinforce and give me a mounting location for the FMIC. Looking like I might want to buy a new intercooler that has inlet/outlet on drivers side. Also thinking that the car will look nice so I need to work over the engine bay and interior.

Scariest part of wide body install is over, going to the greyhound terminal at 8:30pm  :secret:

OK, got projects out of the way.
Installed the Aeromotive FPR to handle larger return flow at idle.
Installed the Walbro 450 pump.
Ordered Cleco clamps for widebody rear panel fitment.

NEXT: PAC1218 valve springs and Brian Tooley push rods
TO FOLLOW: Oil Cooler, Trans Cooler, Intercooler installation and fitment with new air dam

Intercooler setup along with trans and oil coolers plus the large RU-3220 air filter will take some time to fit up front but be worth it I think. Piping inside the engine compartment is no problemo, just move the PC680 battery forward a little more, it has couple inches left to move forward.

Made a push to midnight with help from the wife and got the following done:

  • Pulled the injectors to inspect since E85, I also run pump gas and switch between so turns out the injector are clean.
  • Changed valve springs to PAC1218
  • Changed pushrods to Brian Tooley
  • Changed plugs to BR7EF gap .028

Car is dirty, maybe I can wash it up this weekend?? Dirt road country dust eater. But the views are nice out here and it is quiet.

re-fired and tested, seems ok with the new parts.

I spent some time this weekend looking at wheel offsets and combos to work with the widebody kit. I have BC coilovers on order, waiting for those to arrive to see if they make any difference for clearance on the front to the strut tube. On the back I already had sort of coilovers using QA1 springs on stock struts. Since I have the TASA setup my rear offsets are a lot different than Joel's setup. I have wider axle rotor to rotor. This sort of makes an issue, now I need more postive offsets on the back, face of wheel flat. Then on front almost negative offset so face of wheel is dished. It would require too much spacer on the front to use similar offset wheels front and back. At least this is my first real look at it. Thinking I may buy a couple cheaper wheels to get me started and see how I can fit things. I could even out the problem because I need to change to the ford 9" outer bearing so this requires cutting the axle tubes and buying new axles. So narrowing the rear is an option so that front and back would use similar offsets. I doubt I will do that. As it is I would end up with something like 18x11 with +25 offset on rear and 18x10.5 with zero offset on front( but still need spacers I think or go negative for offset). I think it ends up like a ~2" difference on offset of front and rear.
