Hey guys, I'm wondering if anyone out there has heard of a stroker kit for the 6G75?

I'm wanting more cubes in the old ARS55 but I'm not keen on boring to much with the turbo setup. Ideally I would want around 4.2-4.5 sort of area which I assume would be about the limit you would want to go with just a crank.

I'm all for this, just have to watch the rod to stroke ratio for revability.

i'd like an idea of a 4.0 :)

Not available apparently. Hopefully the US boys come up with something or suggest to rpw to make one?

Your best bet is to find a company that specialises in custom billet cranks and perhaps seeing if they can fashion one up based upon the stock crank. Probably looking in the region of $5k though. Its a complex and time consuming job

There is a company in the states that will do these for the 6G series engines but I would have to go searching for their name ....

Here is some really good info - http://www.galanttuners.com/index.php?topic=521.0

Apparently the 75 crank can be dropped straight into a 74, giving a decent displacement increase.

Brian Crower does do stroker kits for all manner of cars, and had previously created a kit for the 6G74 for hyundais v6. Cant find any reference to it though. However, this PDF lists a cranks for a 6G72 on the last page. It might be worth shooting them an email and asking what is possible with either the 74 or 75

I'll ask the guy behind the scenes for the 4.5L stroker crank. Won't be cheap...

Jeez 4.5L just from crank? Wont that ruin the 'revability' of the engine?

I was thinking a 4.2l may be more suitable. 75 crank into 74 . What does that do?

Torque monster + blower = :eek2:

4.5 + turbo would bring back the 'revability' and great amounts of torque. I figure the head flow good enough stock to handle the turbo so the crank would be doing to low down work. Plus my 6G74 currently revs to the limiter quite easily before the turbo went on so bringing it back a little on a 75 plus the turbo would work quite well in my opinion.

Sticking to the longer stroke crank though, cant imagine a bore would be good idea - the walls are quite thin already.

Also, it might be possible to move the piston pin on the rod, or find rods that have a different positioning in combination with different pistons

I know of a badass 4.2 that exists and is in testing phase!

I do not know much more than that, but this at least means it is certainly possible.

I specifically avoided saying anything about boring the engine. This thread is purely about stroking. I understand that the walls are already thin hence the thread title of the thread '6G75 stroker kit?' is that really hard to understand???

This would not change the displacement it would change the compression ratio.

There is someone that has done a lot of research into this, and yes there is currently a test running 6G75 that is bored out to 4.2lt.

in regard to the OP's request of stroker cranks, From what I've heard there is a limit to how much extra can be achieved.

I believe the limit is appprox .4lt of extra capacity.


Using both, you go from stock 3.8, up to 4.2 with bore out, then 4.6lt with bore and stroke.

That seems to be the limits of the 2 different methods.

On the assumption no-one else has made any yet, I have been told getting newly developed Stroker cranks made up for a 6G75 would realistically require a small group buy scenario (probably 3-5 orders minimum to get anywhere near decent costs, and even then expect between $2-3K each).
