Jis Micheal ..dis bad news oor daai suiers van jou.... :redface: :redface:
Ek weet ons het ten duurste betaal vir wanneer ons ren motors gebou het want ons wil altyd die ligste maar sterkste pistons gehad het, want hoe ligter hoe meer H/P

voorspoed met daai herbou van jou en as jy dit kan inwerk in jou budget moet jy dit as veiligheids maat reel maar ceramic coat..... :salute: :salute:

Sorry to hear about the dramas on your troll Michael.
It just shows you how strong the TD42's are that it could take over 1 bar boost pressure for so long before this happened. At least the damaged was only on the top end and you didn't put a conrod through the block.

Just a thought, but since you've got it all apart and you're going through all the effort of balancing, etc.
Why don't you look at putting forged H-beam conrods in ? :mytwocents:
Then you know you can throw big boost at it at a later stage and it will take it like a champ :biggrin:

Errol yes I was really hoping to get stuff ceramic coated, but its just to expensive at this stage. Looking at around 3k for the piston crowns and 2.5k for the precombustion chambers.

Dustin H beams are almost 9k so its also aout of my budget.
I do however think my current ones will be able to handle the power I am aming for, they are quite strong it seems

Jammer om te hoor van die dilemma met die verkeerde pistons, wys nou maar net soos jy sĂȘ, mens moet maar net die regte parte gebruik vir die regte applikasie.

Sterkte met die herbou, hy gaan verseker sterker wees as enige ander TD42 na die episode. :woo: QQQ

Eish Michael, nou maak jy my benoud! Chuck loop presies 1 bar (met veilige EGTs), maar sy pistons is verseker ook nie van daai die super-duper turbo pistons nie.

As dinge dalk sou breek sal ek ook van daai frisser pistons insit, maar solank alles nog mooi aanhou werk ry ek hom net soos hy is...

Christo, ek moet by se dat die aftermarket NA pistons verseker swakker is as die NA Nissan pistons vir wat dit werd is.
Ek het my EGT's altyd onder 600 gehou, maar selfs dit was te veel vir hulle.

Ek het dit nie in my ander posts genoem nie, maar al my pistons het begin kraak van die gudion pin af na die piston top toe......hulle kon maar net nie vat wat ek gegee het nie
