well been boosting about a year now on stock internals! t25, 450cc dsm's, and the vafc hack set 0 to 5000 rpm is set @ -40 and then -35 to the redline! been pushing about 9 psi. This is the second time its broken last time was 750 miles ago and it had a full rebuild then just rebuilt it again yesterday and obviously i dont want be doing it again! any ideas on whats going wrong? i suspect detonation/pinging! just want some views and opinions..

Thinking about buying some eagle rods and wiseco pistons/ any views?

Get some better fuel managment which can handle timing.

thanks dude, been reading not sure i understand it all but its all a learning curve! after reading i think it could be something to do with ignition timing being to advanced! thanks again

mr gsr, have a stock motor! have broken ringlands on the 3rd cylinder on 2 seperate occasions within 750 miles of each other have stripped the motor and rebuilt on both occasions and its back to n/a at the mo til i can get the parts i need to stop it happening again!

Quit using the AFC hack and get some real management like uberdata. Your timing is probably advanced to hell.

integracivic94

yeah thats what im now thinking!! **** this has been an expensive lesson so far! do any standalone fuel management systems like hondata/uberdata cover timing or should i buy msd? aswell

You need to retard your ignition timing at the dizzy for the afc hack.. PM member BauleyCivic and he will let you know what it should be at..

How do you know when you've broken ringlands? Lots of smoke or something?

I believe you can tell by a compression test.

The engine will run like crap and most of the time it will smoke it's *** off!!
