BUILD: My love-hate relationship with the latest SW20

I might run that next time. I'll still need the friction modifier though as my diff is nuts.

I'd look into the 2 way LSD installed to find out what fluid will work with it. I know that they can be fairly tempermental which could limit your fluid choice. Early style TRD's used something similar being a clutch pack type but from what I know were not all that successful. The gen 3's are viscous but can produce mixed results as they pre-maturely wear out.

The GEN3 Viscous doesn't care what gearbox oil or friction modifier you use. It's a sealed unit and doesn't really wear out, the fluid inside just gets hot and stops working properly when driving for a while. They aren't the best sort of LSD anyway.
The TRD is a clutch pack type and these types can be noisy and do react to what oil you use.

I'll have a look when I pull it out and then I can finally know which lsd it has. The only info I have is in this picture. Which isn't much help

The early factory open diff looks like that in the middle but so does a TRD LSD. The open diff should spin one wheel one way and the other the other way. But you've said it's noisy so it will be LSD. The viscous LSD you can see right through the diff.

Well everything seems to go wrong at once.

Managed to get 220kw on the dyno tune at 1.2bar, tapering back to 1bar by 7krpm. He coukd have pushed more but the intake temps were spiking.
Tuner reckons it's got an issue with 4cyl 3 intake valves. Either a bent valve or the seat/clearance isn't letting it close properly.

Also the drivers door loom had gone faulty so none of the window controls or central locking work.

Title seems appropriate haha

Seem's like Tuner is running at quite a high RPM which is beyond the peak torque figure. Its hard on the dyno to get decent engine cooling as fan is generally pointed at front radiator rather than side vent. Is your A2W heat exchanger up front?

So what's the plan now?

[tooomanyprojects]

Plan now is to figure out my next steps.

Either way I have to pull the box out. So I may as well do the head at the same time.

If I'm pulling the head again, do I get some porting done and just go all out with cams etc?
I still want a streetable car. And I'm at the point now where any futher money spent on mods is beyond what I can get for the car. (Car only owes me 8k at this point including the forged rebuild) so im wondering if i just fix it and then enjoy it.

I've got a lot to think about before make any decisions.

Be good to get other opinions though.

Just an update,

Took the car away over Xmas. it was running great (apart from 4th gear) until it suddenly wasn't. struggled to idle, missing, running really rich and all 4 plugs fouled up.
this happened while driving in the rain, but never cleared up once everything was dry (don't know if its relevant but thought id add it anyway)

strange thing is once your are going, it seems to sort itself out. AFR at idle sits around 11.5-12.5 but once its cruising at 50-100 it would settle down at around 14.3-14.7 ish.
the link didn't throw any codes, and the tune hasn't changed, tried new plugs and new fuel but neither fixed it.
I will be pulling it apart anyway to fix 4th so I'm gonna pull the head and see if its the valve issue getting worse. (i hope nothing is too broken)

if anyone has any other things i can try, let me know. otherwise ill crack on and add some pictures. when i get it apart.

[Benckj]

I wouldn't be tearing into the motor to fix an ignition problem. Could be in ignitor, dizzy or wiring if it effected all cylinders. Might even be a common injector ground not making contact.

[tooomanyprojects]

I know I have valve troubles already, and I need to pull the box apart to fix 4th.

But ill give the ignition a good trouble shoot before I rip it completely apart.

Cheers.

Do you live in feilding?

I used to. I live out near bulls now. Whys that?

Was wondering if you were the guy I saw at the gas station, if you need a hand on the car let me know

[tooomanyprojects]

Yeah mate, that's was me.

And cheers I might have to hit you up if i get myself in too deep
