I'm not sure I understand this, you want to match the SST to the engine build it's a question of how much torque the tranny can take before slipping excessively. People with over 350 wheel tq can't use normal mode anymore since the holding power of the clutches is related to the line pressure.

You can always cram more clutches in there but until they figure out the programming it might be a good idea for long term use to stick to a power level that the SST can handle without big clutch upgrades.

First they crack the tranny tuning, then we can understand better how much power it can take, then you build an engine according to the traits and limits of the transmission. Your probably at the limit already with a 3076r.

 

Well I think by stroking it I get extra power down low and don't sacrifice anything as what I sacrafice is a top end I can't use anyway, that is my theoretical point around potentially using a stroker.

Maybe the difference between Stroking vs Boring is a negligible difference and boring is more reliable, that's one question I'd like to see answered/debated.

The question isn't 'should I build the engine?' it's 'how should I build the engine' for my situation (and for other SST owners).

If I decide I want more than the 3076R can do (likely) then I'll upgrade it but I'm not planning my motor build around my turbo.

I would like to say option 3, not having to resleeve the block means significant drop in chance of the engine builder messing something up leading to dropped sleeves/problems.

That's a good point as well and that was the one I liked the look of too.

I'm wondering what the side effects of such a big stroke is since I know AMS doesn't stroke the motors they sell (at least the ones they advertise) and I'm not sure if there's a reason for that (Cosworth sells a stroker kit though)

He is working with a good team of Australians on the SST side of things.

Correct, Beeble is tuning the car and he's doing a big motor build himself on an SST.

Some people with much more built motor/SST experience than us Aussies have run into problems with high revs and getting the SST to shift.
My understanding is that 8500 is about the limit, and beyond this the thing simply won't shift. I have no first hand experience of this because no car down here revs that high! well maybe one i can think of, but it's in another city, and i believe Kozmic had a lot to do with setting that car up anyways.

I'm a big fan of sleeves for a track car, but i can't say for sure if any Aussie shop has experience with sleeving 4B11s. Your car will be mostly street so maybe that's overkill.

If you want a safe approach i would keep stock or near-stock displacement.
heh wait and see how my 2.2 goes before deciding on anything
I suspect I'll be looking for help myself very soon, local and abroad, as we enter previously uncharted waters with tuning big power SSTs down under. I'm 100% sure we'll get there but there is some significant learning to be done.

 

Thanks mate, great info as usual. That's why I posted it up on here since I know the guys in the US have way more experience with this stuff and I want to do it right rather than cheap but when cheap is right that's even better - <$2k for the engine parts + Labor sounds pretty good (depending on how much labor is required).

Glad you're going first on the tuning front - Exciting times ahead for Aussie SST's, we've already got the quickest MR quarter mile, what's next?

^ I'm just going to pitch a tent in the corner i think.

Just sleep in my car, it'll be in the corner next to your tent

^ Same here.

Will speak about a quote when I come down to pick up my car

 

Late nights on the dyno here we come!
