busted ring lands... own3d

[silvertuner98]

just figured id share this with CC as well. well a buddy of mine layed down 310whp 230wtq with a boosted b18c1 (stock) @ 12 psi and a very conservative tune. well finally he started having smoking issues and sucked up a little water. we have a feeling this problem was started a little BEFORE the water and boost spiking issues. here are the results of this. we pulled the engine and took it apart and found something a little wrong. please note that all the busted ring lands are on the INTAKE side of the pistons. as well i am posting the stage 5 unsprung clutchmasters clutch he uses to show what it does to a stock flywheel and the pressure plate . leave some feedback, thanks

those have definately seen better days, haha, but as for that clutch and flywheel looks like pretty normal wear and tear (from what i can see of the pics at least)

was the flywheel resurfaced before the clutch was installed?

Welp... Something is wrong. Sorry... I drink

LOL, wow, we JUST pulled teh pistons out a my spare DOHC ZC block and SAME thing on 3 of the 4 pistons.i think the guy ran too much boost on them.

the were also on the intake side only. thats supposed to be the thrust axis. amazing

 

[Chris.]

imagine that....same type of problem on two diff motors by two diff people! no wonder i got that block and the SI motor and all the s**t i got for 200 bucks!

 

[silvertuner98]

yea about that thrust axis... lol. he had boost spike to 20 psi and ran it through a puddle too so umm yeah lol. the clutch is normal, thats after only 3k miles tho lol. cant wait to get this thing back together. 400whp is in the future

 

[Steven.]

i caint wait to get my zc backtogether, i miss my hatch

after seeing someone blow up 3 d-series engine with MILD boost, ive decided against any D-series and most likely will pursue an H swap with some boost

 

[Steven.]

ZCs are stong D series, im only goign with about 6 psi. KKK K26 turbo, external wastegate. Chipped ECU with turbo edit, 450cc injectors. DSM BOV, HKS turbotimer. and some other goodies.

 

[silvertuner98]

those are some huge injectors for ur set up. but better to have too much then run 104% duty cycle i guess

I don't know why everyone goes with huge injectors right away I'm using 310's and I have my fuel maxed all the way down but then again I'm tunning with a safc2. It's better to run rich than lean I guess

 

[silvertuner98]

yea but its also not good to run ur injectors above 90% duty cycle either. i suppose 25% duty cycle is better then 98% duty cycle tho

 

[slowhatch]

RC recommends 80% duty cycle max

I bought an Alfa Romeo once for $500.

the #3 piston looked like that. It smoked like a b***h when it warmed up. Like SeaFoam X100.

It wasn't from boost. It was from being Italian and poorly made LOL!

 

[Chris.]

lol seafoam x100 lol

lol

im using turbo edit so it will automaticly adjust idle and fuel maps for 450cc injecotrs, plus i got them for free. and i have a larger fuel rail.
