How to increase VK45DE Horse power ? I have many engines get tuned and inrease their power. But , i haven`t seen VK45DE tuned.

The only actual aftermarket parts I have seen are a stroker kit. There may be a supercharger kit around or you could try doing your own turbo kit. I'm guessing there wouldn't be a huge amount of space in the engine bay so a twin screw supercharger would be your most cost effective way to increase power. A 2.3L whipple would be about perfect.

Seen a couple of fuga's in japan with light mods but its almost all custom. IMHO a twin screw supercharger set up would be the best way to easily get some power out of them. That is of course unless you are knowledgable with N/A tuning and wish to work on your own stuff.

EDIT: The nissan GT500 cars use a race version of the VK45DE thats down to 3.5L and makes 500hp from memory. From some of the pics it looks to have a magnesium block or something.

standard bits such as intake, headers, and exhaust will net you some hp.proly toss on an safc to lean out the top end some and thats proly as far as you can go without digging into the ecu which iirc is locked.
