Dura stroker and stock stroke steel billet crank

I am in the works to do a steel billet crank theese will cost in the 1400 to 1600 range

I looking to see how serious people are about a steel crank for the Dura engine both 2.0 and 2.3

Those that are i will require a 50% deposit up front and Bal when cranks are finished , If i put out the money for these thay will be in the 1800 range later

I am looking to do a stroker and a stock stroke

If we can get 6 or more the price could drop by 200 or more

Here it is now lets see how many truely want to make power with the Dura engine

Tom

My ranger crank should be good for a while, I do know when I do a sleeved block I'll use one though.

The ranger crank and the Focus crank are the same when it comes to rod and main sizes and the ranger is no stronger that i can see

yeah, but it doesn't have the big ring gear to drive the balance shafts. Cosworth had regular focus cranks breaking a bit lower than the ranger crank, so it's a bit better than the regular one. You don't have to change rods, but there is absolutely no reason to hold onto the pos stock rods as they're the part that is going to break first.

ok Tom truthfully do you have to blueprint and/or rebalance your engine after a crank like this is installed? and you might want to refresh people (like me) what are the pro's to getting this crank, how much hp do you think it can hold, and the new displacement this will be on both the 2.0 and 2.3. Thanx I trust your products are quality ones being that I havent heard any complaints for the 3+ years I've been in the scene.

What will the displacement be with the stroker crank? $1800.00 bucks is no small chunk of change for a four banger crank, the displacement gains and associated horsepower gains should be given before you ask people to commit to buying this piece.

I asked you this on another thread, but how does the 3.0 Duratec that will supposedly be in the Fusion get its displacement? I myself am a displacement/torque fan and will replace my 2.0 with at least a 2.3 this spring or summer (the wife even OK'd it!) via either a Marcy bottom end or one that I will have assembled here in Indy, just depends which route is cheaper. I also see that you will have bottom ends available (comming soon) whenever "soon" will finally be. I have time to wait, but would just like to know what the power gains for these units might be.

It's a steel crank turned on a lathe, depending on the grade of steel...............you can blow the freaking head off, crack the block, break rods and still have a crank that can be rewelded.

Hey Big bud.... the 3.0 in the Fusion gets it's displacement from two more cylinders

Fusion

This is the plan

2.0 will be offered
2.3 by adding the 2.3 stock crank to the 2.0 block and custom rods and forged pistons
2.5 by adding larger sleeves and the stock crank custom rods and forged pistons

2.3 will be offered
2.3 steel crank custom rods and pistons
2.5 either larger sleeves steel or stock crank custom rods and forged pistons
2.? steel crank custom rods forged pistons

We will also be offering the blocks with larger sleeves if you want to do a engine build your self and the cranks by there self

For easy math on HP TQ will be much much more take the HP your making now 160 divided it by the 2.0/2.3 what ever you now have then X the size of the engine you are looking at

like this 160HP divided by 2.0 = 80 then times the size your going to 2.5 = 200HP add into this cams , ported head , and you could see an easy 240hp and about 220TQ at the wheels on 91 , THIS IS QUICK MATH AND ONLY TO GET IDEAS AS TO GAIN all Foci will be Diff but this is close

Our goal on this engine is over 800 with our turbo kit and i think we can do it and keep it street legal

Tom,
Once you do something crazy like +600hp, im sure many people would want to do the same. but for people like me 300HP is more than enough.
