different pistons working together

[Shift n Drift]

ok so i blew my s14sr, rod through the side of the block.
i have everything in good condition in another block, but its s13sr block, so ima source out an s14sr block, but in the block that blew i have now 3 good Wiseco pistons, dont kno comp, or size, but will when i open that motor, and i also have 3 good cp pistons 86.5 size and 9:0:1 compression, im thinkin of putting the cp's in cylinders 1 and 4 and the wiseco's in 2 and 3, so when it fires it goes

CP-WISECO-CP-WISECO, 1-3-4-2

i think ima say screw it and do it, any input/opinions about this are welcomed/wanted

the head is going with an hks step 1 256 with 10.5 on intake and greddy easy 264 with 11.5, going along, suby yellow top 550 or 525 injectors (whatever they are), a g20 60mm throttle body instead of the 50mm, and an apexi power fc, i have all this right now.

input on setup is greatly appreciated

Why would you mix and match pistons?

[180wanabe1]

the big thing i would worry about is weight between the two companies. if you can balance them all to the same weight i don't think there would be two much issue. but also if the ratios are off then you could potentially have problems there as well.

Just weigh them and get them within a gram ir even closer and do the same with your rods...then balance the rotating assembly together should not be a issue...as long as they the same compression

yea ill findout exactly what ratio the wisecos are next week when i pull it apart, the weight of them i think is about the only concern, cause each cylinder does its own thing,

the motor that blew, i got from gippy87, and i put a good 10,000 miles on it.

why mix pistons, i dunno, my theory is i have 6 good aftermarket pistons and each cylinder is its own individual, im just trying to make ends meet

[PoorMans180SX]

You can probably buy one piston from Wiseco.

[Shift n Drift]

if I can, shit, then again maybe I wil

[gotta240]

as stated above, you should be able to get a piston from either manufacturer. I see why you think mixing would be ok.....but honestly, its asking for disaster. Just spend a few bucks on one new piston

[Memberofthe600hpkaclub]

On a side not e...we had a 347 that burned a piston...we endend up using a chevy piston just in the one hole and its still going strong 20k later

Then again we were already using 6cylinder chevy rods in a ford block
