I REMEMBER A KIT THAT WAS OFFERED FOR THE 996 THAT MADE THE ENGINE A 4.3 OR 4.6,IF I REMEMBER CORRECTLY IT WAS OFFERED BY MERIDIAN AUTO.DOES ANYONE REMEMBER THIS OR WAS I IMAGINING IT?I HAVE CONTACTED MERIDIAN AND WAS TOLD THAT THEY WERE NO LONGER WORKING ON PORSCHES(ABOUT A MONTH AGO).I WAS PLANNING ON BUYING A HIGH MILE 996 AND DO A STROKER KIT,AND OTHER MODS TO MAKE IT A NICE TRACK CAR.SOMEBODY HELP PLEASE,GENE.

 

There is no mystery about a stroker. Add your mm to the crank.

 

I UNDESTAND HOW TO MAKE A STROKER,BUT I THOUGHT I REMEMBERED A KIT ALREADY BEING DONE.IF I'M WRONG I'LL START DOING THE MATH AND CHECKING ON GOOD MACHINE SHOPS.

 

I'd love to learn about an affordable stroker kit as well for the 3.4L. A 3.8L kit would be enough! .....did I just say enough, you can NEVER have enough power. A 3.8 would be OK!

 

racerjsz,

When we stroked Killer Angel, we sent the crank to a shop in the LA area where they stroked the crank. What they do is weld additional metal around the journals and then re grind and then nitrate the crank. I'll get the name of the shop for you.

 

i think reading about the german tuner Koro offering higher displacement, as well as US tuner Protomotive. may want to contact Protomotive, i think they are probably easier to deal with.

 

Sorry for the late reply. The crank shop we used was CCR (Custom Crankcase Repair).

 

do they have a website?

 

Not that I am aware of.

 

Yes Koro offers a 4.6 GT3.

Auto Bild magazine tested it and recorded 0-100km/h 3.8sec, 0-160km/h (0-100mph) 7.5sec and 0-200km/h in 10.9sec, fast or what?



The specs for the motor are 480hp/7300rpm and 500Nm/5000rpm.

 

that 0-200km/h is FLYING! i wonder what the redline and gearing on that car is like.

 

9ff do 4.0 kits. According to Porsche that is about the limit.

4.1! I stand correcting myself.

Now this is just silly:

A 4.0 L is accomplished simply by adding 104 mm pistons.

 

the 4.0L motor features considerably more upgrades than that...

 

So what is the highest capacity obtainable with stroke and bore?
