  • B6304 conversion

So time is looming closer to me starting a conversion on a 264 from prv to B6304. I have stripped the 960, engine gearbox, down pipes, all the looms from the ignition barrel to the indicators, rear diff g80 and tank pumps etc.
The 264 has the engine, gearbox and wiring from the bulkhead plug removed and a pug enthusiast is collecting the prv.

So I have been reading lots about the conversion and my question is about the gearbox choice, obvious one is to stay stock. But manual is the real want.

What are the options, well the T5 is the most predictable one but I have been reading about using an adaptor and bolting an M46, M47. Has any one done this?

I know @Philia_Bear has done this conversion but he manipulated the aw30-43?

Any input will be great weather it's positive or negative.

Cheers Gav
Have you considered going with a whiteblock M90 if you're keen on going manual? 960s with manuals in Europe had the M90 fitted from the factory.

I don't believe M46 or especially M47 will be strong enough for your long-term needs. Syncro rings and some gears are NLA as far as I know for them now.

Alternatively there's the Borg Warner / BTR / Tremec / Whatever They Call Themselves This Week T5 gearbox. DeeWorks makes a whiteblock adapter plate for T5 gearboxes, I believe @Slowbrick got one for his T5 with T5 project. AFAIK all whiteblocks have the same bellhousing pattern.

Also... what ECU do you plan to use? There are (at least) two types of Motronic 4.1 factory units, one with immobilizer and one without.

I will be following your project closely since I'm planning a B6304 swap for the 780 eventually.
M90 in 264 will have the shifter in a bad spot

Someone (I forget who) makes a nice adapter to put a Toyota trans onto the stock auto bell housing and it works stupid well

If I was doing something for long term use... I would be thinking about one of the gm manual 6 speed boxes that has the cable shifter
Agree with @Philia_Bear - look into 1UZ to W58 adapters as 1UZ toyota engines have the same auto bell to box pattern as whiteblocks - unsure of input shaft length. Nice shifting box, sturdy for NA I6 applications (how it was delivered stock) and good ratios for it. Will fit the tunnel as well.
@bgpzfm142. Wiring will be stock moronic 1.8? from 92. As far as I can gather it had a factory alarm/immobiliser and it was professionally removed, I'm not looking at any power gains or pushing more hp.

I do like the ldea of putting a shift kit or wiring the valve to day paddle shift on the aw30-40 but it's still no manual.

I have read about the T5 and there are plenty of adaptors avalible, I think vee-que even makes them, but I'm not to sure what I have to get to make it work? For a white block, flywheel etc is easy enough but the start talking about changing the input shaft, then possably making a custom drive shaft?, lots of questions

@Philia_Bear the Toyota trans is that the w58 your talking about?

Can get adapters for w58/r154/the supra gertrag 6 speed
I would not ever even think of reusing the shit stock ecu

Ms1v3... cheap and has better than stock tunes available for it... much better long term diagnostics as well
Also not afm based which makes intake plumbing easier to deal with
Yeah @Philia_Bear the stock diagnostics are a bag of shite. Again I have looked into it on the surface with Ms but at the time it confused the shit out of me. Your running ms1v3 on the tentical wagon? How do you find the paddle shift?

Ms is easy and lots of support for it here and on t-bricks

One of the pre assembled kits from diy is my recommendation for ms1 v3 running the high resolution ms extra code
Ms2 and ms3 are more complicated than you need for wasted spark batch fire on the 6 cyl

Paddle shift is just what it is
Great for towing and track use
Makes heavy traffic much easier than a manual

Having 2 do the shifting manually all the time can get old eventually in traffic

I'm going m90 in the wagon now only because I never expect to race the car ever again or drive it in heavy traffic


@Philia_Bear, sorry for all the questions, it's just the standard ms1v3 assembled kit and pig tail, wire up to the motronic plug? And I do like the sound of paddle shift.
I would run the stock ecu for registration purposes at the start. Wiring in an ecu from scratch is not as simple as mike makes it sound.

I'd go for the auto and then down the track look into a manual box. The 1uz auto adaptors are the same pattern as the Volvo auto so it's not too hard to use them.
Thanks @Vee_Que, I'm not sure if it's all the abbreviations they use with Ms, but it takes a bit to get your head around.

The car is a while off I still have to get the engine mounts made up for the 240 cross member, rebush the whole car, new Springs, shocks and strut tops etc, etc and possably a respray.

Stripping just the wiring you need out of the 960 main harness is imho far more complicated
Also the ecu can get unhappy with lack of a number of inputs from other modules

You have less wiring with MS than the moronic system and it's honestly better documented at this point than the moronic system is

Neither of them are simple at all... been there and done that 4 times now (God dam...)
Msv1 will fit in the moronic box... so.. from a engineering perspective... it's the stock ecu box
Yeah the fun bit will be stripping all the wiring from the loom and not fucking it up. I can see pros and cons to both.

Cheers, it's a one owner fsh, and 4700000ish km.
@Major Ledfoot, thanks for the link I was just reading that post yesterday afternoon.
Nice. Looking forward to seeing some pics of it and the build. Any rust in the body?

No it just has some pitting/stone chips
on it, was in the weather belt in sw WA on a farm parked up in a shed for 15+ years, the interior is very original and untouched but the mice had made a home in the engine bay.
