S52 Stroker using S38 components???

[e30polak]

Is it possible? that would be sick to do a 3.6/3.8 s52!!! Anyone with info please post up. BTW I haven't found anything with the Search function.

Any other stroker options?

I think you can do an m30 stroker with an S38 crank......but not S52.

im pretty sure this is correct. A S52 stroker just sounds mean. I think some of the only options will be aftermarket.

There are people out there who have offset ground cranks to attempt this. PTG did stroker S54 for a while also, I think. I would imagine they had the budget to have a new crank made.

I wouldn't touch an offset ground crank with a 10 foot pole. 3.2 is plenty for plenty of power, and if you want more (especially in a street car) go for boost, not displacement.

especially if it will see over 6000 RPM

It's ok. The M50 head flow sucks over 6000 rpm anyway.

With factory port-work, you're right. : )

M50 head casting is the same as the S50/S52 as far as ports and combustion chambers. Assuming you meant head as a complete piece aka with cams where as the cams are inferior. :)

What is your opinion (or Dad's) on VAC's Stage I and II heads? I want to Sunbelt my S52 down the line and am looking into my options...
