So I decided the whine was too much to live with and i pulled this diff apart too.
The lsd is awesome, near new but the crownwheel and pinion were so worn that they couldnt even be lapped and used again. It also had 1 shinky wheel bearing.
So now Ive just finished having my spare 4.5s lapped, my spare housing cleaned, and I just bought enough wheel bearing kits to rebuild both diffs. The bearings alone were $400 just for the axles.
So anyhow, Im going to have it all rebuilt asap and then it should be mint!
Diff is back together now.
Rebuilt 4.5:1 with trd 2way, new axle bearings, new axle seals, penrite 140 weight lsd oil. Even a new genuine toyota lsd oil only decal for the housing. Looks mint, goes great, really the ideal ratio for a street driven 20v.
So been doing further development.
Now have a narrowband 02 sensor connected, getting better fuel economy hopefully. Seems to work fine in closed loop at low load moments.
I have now purchased an ECU data scan to monitor the ecu, and to give me a correct speedo now that I have changed final drive ratio. im in love with this thing, especially the history dash. It plugs in via the serial laptop connection to the ecu and it display about 30 different parameters that the ecu is calculating or measuring.

Made an alloy trim to guide air into the radiator. The car is running pretty cold around town, I use a 72 degree thermostat and it only opens when the car sits still, any time its moving its in the 60 Centigrade range.
what sort of economy are you getting on a full tank matt ?
I can go close to 500, over 500 on the highway. Thatd be run to bone dry pretty much.
I usually do around 400 then fill up as its not good to let the tank get too low as the pump gets louder when theres no fuel to dampen its noise.
Hows yours going now? Had it all fixed?
looking good matt. have to catch up soon, i just bought a moto so if you've still got yours, i think ot's time for a ride haha
Yeah still got mine, havent ridden since january i think, bit due to go for a blap.
Been doing plenty with this car.
Now I have fitted a wideband LC1 from innovate motorsports. Been data logging and tuning for a while, go a lot more power and driveability happening, and also found a new function on the adpatronic that does useful things for itbs. Ive refined my trim figures and all my corrections.
I relocated the radiator slightly to the passenger side and this allows more air to my inlets.
Ive ordered a new vvt solenoid as mine is starting to leak oil on my headers occasiaonally. Ive also got a new top cover gasket, oil cap seal, and top cover bolt washers to seal up the timing cover once I refinish it, it sweats a tiny bit of oil around the cap and seal so its time for new ones. I think ill ceramic the top as Ive never seen a 20v with a polished cover on top before and I think it would look porny. Going to file the cating marks off it and buff the thing with 2000 grit first to get a smooth look to it.
Presently Im trying to get in touch with Rick Sendall to find out if he can do a harness bar and some rollover protection for me so I can go hard at the track.
Went to the drags a week or two ago and did a 15.69 with the new shorter gearing, I increased rpm to 8500 to get the same speed in gear and more or less broke even on times, I did get my best 60 footer with a 6000rpm launch. 2.125.
looking goood, coming along brilliantly
looks fuckkking tidy matt, have to catch up soon, it's been too long. Your number still the same?
