As the title says.

Only replacing it 'cause I am doing a manual conversion. I've never driven the car with it in so can't guarantee anything. Money back if it doesn't work :)

Southern Sydney - If you want to organise freight to pick it up from my house, know yourself out. Otherwise pick up any evening.

Cheers,

Daewoo

I'll take it, pending the time to swing out there to pick it up! Wont be till June or July.

Probably won't be here that long...

I don't have any garageing... all work is done in the driveway, and I don't like the place looking like a wrecking yard... send me a PM about it if you like...

BTW - how freaking heavy are they... ditching that weight is a performance mod on it's own...

Cheers,

Daewoo

What year MR30 is this from? I'm after an 84/85 four speed auto and would gladly pick it up.

I've thought of another angle, even if this is a three speed it would be a good exchange unit to get shift mods done. I can't PM you (not enough posts), can you PM me?

Peter - PM Sent.

It is a 4 speed i.e. has overdrive.

Cheers,

Darryl,

That sounds great. I'll be in the metro area on Saturday (live in the Blue Mountains), please PM me where and when. If Saturday's no good, any time to suit you.

Pete.

I realise this has already gone but have a general question...

Does anyone know if these 4 speed autos will bolt straight into an earlier series MR30 (to replace the 3 speed auto)?

Yes & no...

If you have the correct flex-plate, they will mate up to the engine no-problem.

BUT, the gearbox x-member is different - you'll need to remove the gussets in the transmission tunnel that provided mounting points for the 3-speed, and drill the floorpan to suit the bolt pattern of the 4-speed member. The correct shifter plate, tailshaft and console surround are also required. (Note that the spline on the extension housing for the tailshaft yoke is a different count to the 3N71B, and FSxx71x series manual boxes...)

Thanks for the reply. More changes required than I first thought. Looks like all the way down the driveline (and maybe the diff too?).

It's probably more sensible for me to fit a 'younger' or reco 3sp auto trans.

Depends on what you can get from the donor car... other than cutting out the gusset, and drilling the floor, if you are stripping a car that had a 4 speed, you should just grab everything, and you will have everything you need... The thing I would be most concerned about is whether the ECU is the same...

Thanks for the info. Don't have a donor car unfortunately so...

I'm looking for a flex-plate, tailshaft, shifter plate and console surround for series 2 R30 4 speed auto. Does anyone know if any R31 items will fit?

(So far have located 4N71b auto trans, cross-member and VL driveshaft).

      S15 Spec R

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
