6284T6 into a 96 960

I'm somewhat tempted to swap my motors over, but at this point they both have only one thing going for them drive train wise.
The 960 has the slow motor and has the LSD
The S90 has the faster motor with open diff

If I were to swap one into the other, one would just be a slow ass thirsty whale. What would an piggy back ems do on the S2 system/motor power wise? Or would I need to go proper rather than piggyback?

Just to confuse things- a better, shift pattern for the gearbox would seem to help too from what Alex is saying.

A simple modification to the gearbox and/or a TCU modification, swap possible?

mr300

Do you have something in mind for the shifting alterations? I'm going to the mechanics tomorrow to get an estimate on a cam swap job, but Trans shift patterns could always help if improved....

Switching it to manual shifted auto is pretty easy if I remember @Philia_Bear s thread from years ago correctly

mr300

How would that work? It's a 4 speed with 3 settings/levels?

You change the shifts from being computer controlled to flappy paddle controlled

No... I bet on a compression test they would be the same, the auto is More likely knackered.

mr300;95872 wroteYea that's why I didn't think adding a turbo would do much, because there's just fuck all lift. Do you think it would be worth doing though? Even if I just got the extra power to match my S90 which is a 6304S

Well, a little cam will make a lot more power with a turbo than without.

IIRC, the early/big cams make peak power well above the standard rev limit, and are actually pretty useless. Certainly my first (early) 964 was amusingly fast once you got the revs up, but it was pretty doughy down low and felt like it was overcammed and overgeared. Would have been passable as a manual, I guess.

The later cams made good power till 5500RPM and were overall the much better choice under the stock EMS
They had less lift but made more total torque and more usable power

The early cams work dam effing well with a turbo and stock are good for >400KW with a properly sized turbo and zero head work (and some normal bits of work like a good exhaust manifold and EMS and intake)

The intake and exhaust manifolds are both total crap
Putting on the dirt cheap ebay M50/M52 manifolds is easy and combined with exhaust can make a world of difference to the stock motor. The 6 legged squid on the intake is also.... interesting.... the tubes are a bit long and the plenum is quite large... swapping to the later T6 manifold in combination with modifying the later manifold for a front mount inlet also delivers large gains as its not tunned for off idle torque like the squid is...

RE CAM lift... the head wont support much more than 11MM from memory without extensive modifications, the NA cams are actually pretty good... volvo just compromised on everything else...

J pipe onto the stock manifolds would be mehh due to space on the RHD cars
Log manifold with a T3 inlet Holset works fine...

So I'm kinda seeing mixed things here (sometimes I over think shit) so the bmw exhaust headers and the T6 intake, what would I expect to see out of that?

Spac

Maybe the real answer is a B52x4T swap?

If you were to go down that route, bear in mind you will have to port match.
They are slightly different. Not much, but enough. Local guy here in Melbourne in the middle of this currently

Alot more work just because of the oil pan
The xr5 motor seams the better option because of the intake and exhaust stuff all pointing in the right direction

mr300

5 pot is out of the question. It's a daily so needs to be off the road for as little time as possible. Plus you just can't find a turbo 5 pot over here that isn't dead.

Im embarking on a similar journey into my 240.

I think it was the Poi who was running a B6304+T. He ended up cracking one of the cylinder liners at a moderate boost level. From that experience not many people have bothered doing the B6304 as it has no become much more economical and worthwhile to do the B6284 as the cars are getting cheaper and so are the engines.

From my reading (not actual experience) the successful formula is to grab yourself a B6284T and throw the turbo system away. Then get a BMW M50/52 exhaust manifold plate and make yourself a manifold or shoehorn in an ebay M50/52 turbo manifold. Then throw away the stock intake as its far too large to fit in a RWD layout and make your own. Nathan on turbobricks might be able to help make you one.

Then you open your B6284T and throw the rods away. You then buy yourself some new B5234T rods and pistons if you like and throw them in. The B5234T stuff is the same as the B6284T so you just get 6 of each part. The B5234T has an 81mm bore much like the B6284T.

Then you throw away your B6284T head and put the B6304 head on with the 92-94 cams. The B6284T head and cams have VVT for the warm up cycle only and is not beneficial to you. You can probably control them with your EMS but they dont provide much benefit.

If going auto you then mate it with an AW box out of a 960. If you want a manual you can now get a whiteblock to Borgwarner T5 adapter. I have one and its saaaaa nice to look at.

In regards to the turbo you will need to block one of the drains as the T6 blocks have two drain holes. I believe a 60 trim turbo would be nice for a daily driven auto for a mix between spool and power.

Then you pick your EMS, wire that shit up.

I think some people have also used the B6254 by swapping out the 3ltr crank and using the T5 rods and pistons to make it a 2.8 but I think by having the 2.8 you are already onto a good thing. The 2.9 can also be used but I believe it has an 83mm bore so cant use the T5 pistons which increases your parts cost.

A basic single turbo T6 setup should be able to make 300 crank horsepower all day everyday with little work outside the installation and a small increase in boost.

I need to move into my new place and get cracking on mine!

As soon as you said open it up I knew it wasn't going to happen. Don't have the time or money to be going inside.

However, @slowbrick's advice may be a guide on what to do with my 780 to give it some punch. The PRV, even with its Eagle Premier heads, didn't have the desired oompf when I drove it from the docks to the shed.

This is correct. If he wants a turbo then I would strongly suggest getting a T6 block or making one out of a 2.5 litre. The 3 litre just isnt cut out for the job. If using the 3 litre then keep it N/A and put a good tune on it.
