I am looking for 76mm high compression pistons. Can someone help me where to get them for good price? I am looking for compression around 12,5:1

Thank you

Lander

I can get you 75mm & 75.5mm maybe 76mm not sure.

76mm needs sleeves in a 1.3 block.

I think that 76mm is maximum what is possible with stock sleeves.

You are able to get that 76mm forged pistons, high compression? Brand? Weight? Pics? Price?

For pistons like that you may have to get them custom made. I had some forged aluminum ones made by Wiseco, I was happy with the product. Look them up they can make whatever size you want. 76mm sounds like you may crack a sleeve or toss a rod if you are not carful. For 3 pistons and rings from Wiseco cost $350 USD. That should give you a rough idea of price. Good luck

That is very good price. Where to get wiseco pistons for that good price??? Nice will be 76mm and 12.5:1 compression. Do you have pics of pistons? Weight?

Here are the piston specs from Wiseco on the build sheet.

Bore Size: 2.9520" @ suggested clearance of .0030"
Piston gram weight at inspection: 261.5-262.0

Wiseco is in Mentor Ohio (440) 951-6600. They make very good high proformance stuff.

For $350USD it came with pistons, wrist pins and pin retainers.

For your GTI motor they can cut the valve pockets where ever you want and you tell them what size and compression you want. They may need more info about other things. Give them a call or look for them on the web.

Here are some pics.

I'm working on same project just like you.

I try to put 76mm piston in my g13b DOHC.

I wonder to put daihatsu charade 1300 16v piston but with modification in the top off it. the Dc 16v piston is 3mm higher, we must chop it to put on.

Other option that people in my country do is use Honda D13 piston, but still to chop the top around 2mm. default dia 75mm, we can use oversize 1.

For best value we could try Dc 1300 16v piston, price <$100 included ring.

Please comment..

25.406mm per inch.

I'm going to suggest a cheaper way of seeing what the manufacturer has in stock and then boring the block to fit those pistons. the Honda D-series came stock with 75mm pistons, so some nice performance pistons for that engine could fit well depending on your application. I know JE-pistons makes D-series honda pistons in standard sizes and then upper sizes in 1/4 mm increments. (75.0, 75.25, 75.5....etc.). So you could check that out.

just a suggestion. Hope you find something good :)
