Forged K1 rods and Wisco pistons

[luke 3mps]

Being bad again. next mods will be internal engine mods. K1 rods and Wisco pistons, cams, fully balanced crank, rods, pistons.. Im looking at increasing the RPM to 7500-8000rpm. This will happen ( all going well) after the barthurst cruz. I can get the rods and pistons to me for under $1000 at the moment. I will be doing all the install myself, will have to send the engine away to get it balanced. i can afford to have the car off the road by than as i 'may' have a 3rd car to get around in..

Any thoughts on this guys? as im starting to gather parts info and tech info now.. i have a far knowlage on how to rebuild engines, but not a lot of knowlage about these.. i have been reading about timing tools for this engine etc.. any info will be greatly appreciated

Just checked them out, nice! go the oversize, that way all your tolerences after machining will be spot on!

you will need a a heap of good measuring tools! The timing tools are essential, diamond washers I recommend for the cam sprokets!

I dont like the single row timing chain design in these motors, 8000rpm scares me Luke! So many little things you will come across while your building an engine, dont waste your money if the part isn't right to start with

[KRNAGE]

awesome! glad to see someone doing it here so i can hopefully do the same............much later on though

[premhk]

then you can NOS it.

I will monitor this Luke, this was my plan for next year once out of warranty, I've only ever balance and blueprinted V8's all my life. The 4 should be good for 8000rpm , I use to rev the 351 to 8000rpm with a race cam grind for road use and yes I have owned fords but prefer Holdens

This will be interesting. Keep us up to speed on progress. Good luck. Is it (going to be) matched with upgraded induction, exhaust and turbo?

[luke 3mps]

I have already got a 3' tbe, and bnr turbo. might later down the track go to a garrett 3076. the aim for me is not massive power i want to widen the power band more increase the rpm, to make use of each gear. with the way the car is now it just keeps 3rd gear breaking free but the power comes on 2500- 3000rpm than slowly goes over 5000rpm i still want it to pull at 2500rpm but i want the pull to last longer. if i start to push 240kw+ on road tyres it will be pointless to drive, couldnt use the power.. so i looking at 220-230kw but with a wider band/pull to 7500rpm maybe 8000rpm. if i have to change up turbo's i will, run lower boost..

[Doug_MPS6]

Sounds good. The BNR has piqued my interest. I'd definitely beef up the internals if going beyond where I'm at now.

But given your "if i start to push 240kw+ on road tyres it will be pointless to drive" I reckon this is why sending it through FOUR wheels is better!! ;-)

This is why I love the MPS6 anyway. Whether applying power to avoid a sudden hazard, skirting around obstructive minnows or seeing some presumptuous wally off at the lights, I love the way it doesn't matter how you put the power down, suddenly or in a smooth build-up, the 6 just points itself and goes like a giant hand just grabs and flings it, and gets the job done with no wheel-spin or drama, even in the wet.

But I do find that one can be so preoccupied with making sure you don't run over that which you intend to overtake that it is easy to lose track of rpm building, so I've come to figure that both rpm and boost alerts are important.

The 3's do suprise with teh amount of grip they get, did me ... im tryn to take what the engine does good and improve what it doesnt, reliability and higher rpm power i feel needs to be looked at. SO in goes the rods/pistons and balancing

[Doug_MPS6]

LUKE, I agree. Given the number of blow-ups reported, I think once one starts pushing these engines past reasonable margins of OEM design or intent, the best insurance is tougher components. I don't criticize the manufacturer for this at all. 90% of the cars perform exceedingly well without any issues. Even if a few stock engines come apart, it's the 10% of us "tweakers" that explore higher limits that are most exposed.

It's interesting that the world is stressing over a few Toyota issues like stuck throttles and leaky brake fluid reservoirs, but we hear SFA about MPS blow-ups being the subject of recalls. If it was an endemic problem, then maybe there would be a recall. As it is, most folks seem to be living with a blow up as the consequence of enthusiasm. But maybe I'm wrong...
