Been wanting to strengthen my automatic transmission (change wave springs and weld planetary) in my evo GT-A, however over the past month ive called up numerous transmission specialists, all of which have turned me down because my car is a grey import ==; Seems like if your car isnt a Holden or ford, they wont help ya, unless you are doing something simple like swapping a clutch or servicing the tranny.

Anyone know any good places around melbourne??

Ive spoken to my tuner (RTR), and they said they can send the transmission over to Adelaide and get it built (fully manualized for $3000), but thats such a hassle, and i dont really want to spend all that money manulizing the auto, rather just strengthen the weak points of the box(wave springs and planetary). Surely there's someone local that works with JDM transmissions. Guys over at Sydney with the same box managed to strengthen their GT-As for 1.5k

Thanks in advance!

I was in the same situation but for a R34.

Ripping it out and having it sent to MV in Adelaide is not a bad idea. I had a great experience with DTM Autos in Geelong, they really know their stuff.

However, a GT-A Auto may not be the same as a R34 Auto.

However they can be fairly busy. Their bread and butter is 'normal' transmissions, so getting something highly specialized in there can take some time before they can dedicate the cranial space to thinking and getting it going.

I am sure you've heard it but manual conversssiiiiooooooon.... is what I wish I did, if my Auto ever dies :P

Thanks man given me some hope!, ill give DTM a call, see what they have to say. The places ive called seem to not want to touch Japanese cars full stop haha. If they do skylines hopefully they'd do evos too!

Hahaha yes manual conversion is also an option which i have considered a lot...., so much more fun to drive on weekends! but so irritating driving in bumper to bumper traffic, which is where most of the driving takes place sadly. To convert to a manual ill need the transmission itself, ECU, clutch, flywheel, GSR speedometer cluster, transfer case, gear shift, pedals etc... Then get the new ecu re-flashed, looking at a whole load of cash and time haha. But yea im keen on seeing how a GT-A would do with 250-300awkw. Already beating Manual Evo GSRs with 20+awkw on me hehehe :P

But yea which ever is cheaper, If all else fails then off to Adelaide it goes :/

When I was looking at getting my auto built the only shop I could find in Melbourne that might have been able to help was GZM Automotive in Thomastown. They used to do the Keas shift kit, the only alternative I found to the MV autos kits. Perhaps give them a ring.

That said I don't have any first hand experience with the work of either shop as I ended going with manual conversion. Is that an option for you at all?

Thanks mate! Yea ill give them a ring too, need all the specialists i can find!

Umm yes and no. Although i love the manuals, I wanted to build something a little more unique and the GT-A caught my eye, the taller gear ratios, the ability to tune the transmission via the ecu, and no loss of boost between shifts was a massive win. There arent many (if any) 300awkw evo GT-As around so i thought it would be neat to build one myself. The transmission sadly was the weakest point.

That being said though i have considered it, and if converting to manual ends up being cheaper, then ill go for the manual conversion. Still, I'm so curious to see the performance of a GT-A with a built INVEC II tranny.

    • yeah i agree paint match stops it from standing out so much, oh that's actually really good to know i was wondering if it would help with air flow now actually having an outlet in the bonnet. Will have to focus on ducting into and out of the radiator now to make the most of it.
    • I would paint match the whole thing to avoid unwanted attention  I had a similar bonnet, paint matched, on my old R33 GTST, but mine was a fibreglass jobbie made by Blitz in QLD, they work extremely well for radiator efficiency and under bonnet temps
    • Does anyone run this kit with factory plenum? Does the adapter and bosch tb fit under factory strut brace? I wanted to get this setup before going forward facing manifold. Thanks
    • small update time, after always wanting a "cool" looking bonnet for my car and always struggling to find one for the series 2 that i liked and wasn't an insane amount of money. Saw one i liked on RHDjapan from D-speed in Japan the price was very good for a carbon bonnet so good infact i was a little unsure how much i trusted it, decided to bite the bullet and with the help of jesse streeter in not long at all it was at my door. Once it was delivered i ran in from work and quickly unboxed it and to my surprise the quality was actually pretty good i quickly removed the old bonnet and placed on the new one to test it out and even the fitment wasnt too bad at all. Then decided to paint the little grille in the bonnet black to stop it sticking out so much.   I decided to not mess around with the hood latch and just install some aero catch hood pins, having never installed them before did some YouTube university classes and i was good to go. fair to say it is not a fun job at all from making brackets so the pins sit nicely and actually cutting through the bonnet but also being very scared of cutting the holes too big it took wayyyy longer than i would like to admit but finally got it there. Then it was time for a quick test drive to ensure the latches actually worked and thankfully the bonnet looked very stable. I still think paint matching the bonnet and leaving just the part that sticks up as carbon would help make it all look alot neater as im not sure how i feel about all that carbon on a very fridge white car but will leave it as is and see how i feel with time.  
    • I think it's bound to happen, you finally get it all perfect, and bam, something will happen. I took a while to get a Commodore rear quarter repaired where a P Plater clipped it. Two days after getting it back, Sarah wiped it out on a concrete pillar in an underground car park... This is why I take forever to repair them, it stretches how long until it gets bent again... 😛
