Wasserboxer forged pistons?
Secoh - December 8th, 2002 at 01:57 PM

Where can I buy forgies for my waserboxer project? or will I have to make my own?

I'm trying to avoid doing as much R&D as possible of course, but if no other options become available then I guess I have to....

Why would you want forged pistons for a waterboxer?
The standard pistons are very tough, 1302 Steve uses them in his turboed 2.1 wbx, and I used 1900 wbx pistons in a 2ltr air cooled turboed engine with no problems.

what revs do you reguarly pull out of it? I intend on using more boost than Steve runs, and would prefer it not to go bang too quickly :P

6000 rpm and up to 18 psi boost.

have you had any problems with the heads lifting under boost yet? I'm dubious about the head stud design...

I think you will find that most pistons are no forged anyway.

Who says that they are cast ???

I think you will find that most pistons are now forged anyway.

I'm sure the Government looks at Forged pistons the same as forged $100 notes...... I wouldn't go around telling any one about this..... You NEVER know who's watching-- listening- looking - So I'd stop all this talk of Forgeries .... and stick to Beetles and Beetle parts.... and stay out of jail.....:D:D:D:bounce

Hi

I have not been able to find anyone that makes forged piston with the depression in the piston like the WBX has for its combustion chamber. The only way I could see around it would be to use a flat top piston with a very low deck, not ideal. I have looked into the Wiseco catalogue and there is a 3.8 inch = around 96 mm for the 2300 Ford motor (#K120A3 & K120A4), I think these are Pinto motors and are similar to the 2000 Cortina motor. These pistons have a valve pocket and could maybe be turned in centre to decompress them a bit more? I have not gone any further than just looking at numbers so you would need to do some investigating to see if they would work, also being only a few mm bigger you might be able to use the stock WBX cylinders and bore them out.
