What all will this kit do for our cars?

vistapony

Hey Rygen...the link you posted shows that the stroker kit is just for the older pushrod 4.0L and not for the SOHC 4.0's we have in our stangs. Did you see it for the SOHC's in a differnt place maybe?

rygenstormlocke

Yea, he said he was working on the SOHC version.

What would you be looking at in HP/torque gain with the 4.5?

Zodiac

yeah, what he said ^.

MSP

N/A you would be looking at about 250HP and about 270TQ.. However, this is a 4.5L all Forged stroker, running a lower compression ratio.. Which means running 20-25psi of boost is a true option or 200-400shot of nitrous is also an option..

Basically, anyone who goes with this kit will be the King of Kings in the V6 world.. LOL!! To some extent.. Like Rygen would say, you still gotta make it stick to the track..

Without a doubt I am going to be getting this 4.5L shortblock for $3500.. I'm not sure when i will get it put in, however it will eventually have to get put in.. LOL!!

Its an insurance policy basically.. I will create a nice dry place for the block in the garage.. LOL!!

Everyone running boost should be making plans to get one of these shortblocks for a rainey day or just for when its time to swap..

Seriously, for the price, I would much rather go this route with with FI right off the start. Its making numbers that are comparable in my opinion for less the cost of most applications and alot more dependable. Im starting a little piggy bank as we speak to fund this thing. 3500s the goal God Id love to get an engine like that up on the dyno and let Doug have a field day with it...

I've been thinking about the stroker for awhile now. I think it would be far more dependable and long lasting than any FI option... and, down the road, toss on an X-charger for even more fun!

It seems like this kit will be a little less expensive that a lot of super/turbochargers... of course, the install costs will be greater so it might just balance out.

I want this engine to last years and years and this might be the way to go.

I hate to be the skeptic, but even with the displacement increase and a very brave 20 pounds of boost, the Stang 6's valves are still operated by an extremely overcomplicated chain driven cam system that you won't want to rev past 5500 rpms. The $3500 (forged stroker longblock) + $4500 (good turbo kit) + ~ $3000 (to get it all put together and installed/tuned in your car) puts you around $11,000. That's alot of money to pay for a motor with a valvetrain too fragile for any real revving.

MSP

The Valve train on the SOHC 4.0 for 2005 has been improved upon.. I believe Doug mentioned he feels comfortable spinning the motor to 6400-6500RPM..

In a forged longblock where the stroke is even less than stock, it should be a safe 7K RPM motor.. ???

AnotherMustangMan

Haha, Doug is a braver man than I.

"Stroker" means they LENGTHENED the stroke (hence the increased displacement).

But I guess your right, any motor is safe to any rpm if the owner has enough cash to replace broken toys.

MSP

I was kind of thinking of the longer rods, which would mean the movement of the piston in relation to the rod, in relation to the crankshaft.. The throw is alittle shorter.. I may have been thinking of a LONGROD setup.. Be nice when we can see some N/A numbers on this setup though...

scrming

hmmm... i don't remember Doug saying that... I know I won't spin my car that fast... we have it shifting at around 5800...

The other thing is the gears on the cams are not keyed! It is an interference fit...

Fazm

the 4.0 heads in my opinion arae only safe to 6000rpm, over that you are going to get valve floast. Ive already heard of some instances of valve float on 4.0 engines at 5500rpm after long use of forced induction.

MSP

You have 2 engines Scrming.. You could get this shortblock, and swap parts off of your older engine..
