so how'd it happen?

 

What you do?

 

I was running a turbo-chipped ECU and FMU for years before I did a rebuild and even for 2000 miles after a rebuild. The rebuild was done this year with pistons, rods, blockguard new bearings and gasket etc. The motor had just broken in and I had a new fuel system and Hondata installed. I was getting tuned and supposedly the sleeve cracked somewhere at around 13 psi making 315 hp on the dyno.

The shop tuning my car told me that the chip I was using was an all motor chip and had caused detonation in the motor prior to me bringing the car in for the Hondata install. Supposedly I had caused a minute crack in the sleeve which was holding until they put it on the dyno. Im still not certain its an allmotor chip with aggressive tuning because I specifically asked for retarded timing in that chip.

My thoughts are the motor was just old and had taken a beating on stock sleeves for thousands and thousands of miles. My philosophy is raising the boost 10+ psi on stock sleeves is just luck of the draw, some people run fine some people crack a sleeve. I know people that have cracked sleeves with less psi. Tuning plays a huge role but theres only so much an older sleeve even with tuning can take. I believe a motor with less miles probably would have held out longer.

Luckily the pistons, rods, bearings practically everything internally can be saved. I had a spare block, saved for a rainy day, like today that im having sleeved with darton. I chose Darton because the sleeves cost 150 each and can be pulled out individually if something goes wrong. Its not a huge catastrophe if something goes wrong that the entire motor has to be pulled out. Everything should be working in about a week or two since darton already had a sleeved B18c1 motor. Im selling lots of things from my old set up btw. Im looking for 350 whp daily on pump and 400 whp + on race gas with new set up. Wish me luck.

 

Those are some impressive numbers. Hope everything works out for ya!

 

good luck with your next rebuild. Just curious as to who built your bottom end that blew up?

 

wow sorry to hear that. im sure your new rebuild will be faster though. gl man.

 

good luck man, those are awesome numbers

i have the same goal

 

have u still got the drag mainfold?
for sale?

 

What kind of "turbo chipped ecu" were you using?

 

same thing i was wondering about.

sorry to hear that, man.

 

Do you think your blockguard contributed to your failure? I have heard they can concentrate the heat to a point and increase the chance of cracking.

Thoughts?

Sorry turbo manifold and FMU have been sold...

Anyways, the shop that did the chipped ECU was not the shop that did the dyno and hondata install, nonetheless it is a well known shop and I dont want to ruin theyre reputation.

But what they did was they adjusted the stock fuel and ignition maps i.e Retarded timing, more Fuel...so that it would be safer to run higher boost levels.. oh yea and they removed the Speed governor and Rev limiter.

Wow, I guess block guards don't work after all..

 

no block guards for me
