Any of you guys running this Pistons ?
Havent heard of it in Dsmtuners yet ,
Is it worth it , its 2618 alloy compared to normal wiseco which is the 4XXX alloy

Thank you

Hi!

I have them in my storage room now, HD1400 (85,5mm, 0.5mm oversize) My guess is that I have them installed and running 3months from now..

As for what alloy is better, I cannot answer that.

If you go the Wiseco site I believe the piston material for all of the 4g63 pistons are the same. The difference is the HD1400's have a thicker wrist pin, .225" wall thickness instead of the .200" wall along with a slightly higher compression ratio of 8.5 vs 8.3. These pistons probably have a higher horsepower rating than the others, it just depends on your power goals. Not sure if they cost more than the others but if they do I would stick with the cheaper pistons unless you plan on making 1000 horse.

The only person that has put up much on them is Jake (evileagle). I'd go on dsmtalk and check out his build thread, he goes into some detail on them. But basically, he's not too happy with them as they grenaded his freshly rebuilt motor at his second event of the season. In theory, they should be a good set of pistons, but with the only person to have ran them on a big hp setup shitting a motor, I'm a bit weary. Then again, not everyone is running a 42r with spray and going 8's.

I am using them mainly because I am in the process of using a very large Borg Warner turbo along with nitrous and Wiseco recommended the larger wrist pin for the extra power adder.

How do these pistons behave when the engine is running? Any trouble?
What piston to cylinder clearance did you get?

Thanks,

John

Edit: I have measured my 0,5mm oversize HD1400 pistons: 85,410mm - 85,415mm - 85,410mm - 85,410mm. This is very accurate.. Reccomended bore for this kit: 85,49mm.

All measures is done at the piston skirts, 90degrees at the wrist-pin, as specified by wiseco.
