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).

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.

      I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.

      What should I do next to hold the head on

      By Gareth87 · Posted

      Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.

      Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...

      Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
