the cost of the custom crank will in the $5,000-$5200 range depending on exact specs selected. rods & pistons to suit will range from $2200 to almost $3500, depending on brand and exact spec. Of course the rod ratios get worse, but thats a fact of life with mods like this.

Big capacity engines are built for torque, not high revs. Simplistically, power equals torque x revs. The ideal situation is you make more torque at the same revs. That is what a turbo does. if you want to rev it harder, destroke it, and make it rev. thats what we did with special (1800cc) S blocks in Corolla rally cars.

I can do either, stroke or destroke it. for the ultimate daily driver, my suggestion is a stroked 5S, with blower, preferably supercharged. i've yet to build one, but some desktop dyno modelling has some great predictions.

who wants to fund the prototype??. I'll do a great deal. Keep up the discussions

Good work Terry & Cindy! This is the first I've heard of these cranks (anywhere in the world). I'm yet to even see a "real" 2.4L 3S, so this good news to me. What are the rod ratios like on that 3.0L 5S block?? What piston/rod combo??

we now have an australian made stroker billet crankshafts available. with correct pistons and rods, up to 2.4 litres is avalable in 3S block, and almost 3 litres in 5S block. not for the faint-hearted or weak of wallet.

we keep a small selection of forged rods and pistons in stock, but obviously not the billet cranks, which are strictly made to order.

We are starting on building a couple more 'street-tuff" 3SGT's, using slightly modified stock cranks. Anyone interested in a upgraded or stock engine should contact us directly. Budget $5000-$6000 for a street-tuff unit, depending on final spec.
