Just got the news back ... my timing belt snapped. Bent some valves.

FUC!

Basically need to rebuild the motor. Now, I may go turbo now.

 

Details, please! How many miles on the belt? Tensioner? Since cam install??

Sorry to hear about your motor - build it back stronger

 

I think you should go 2.0

Ouch dude, what happened?

 

Here's the story.

Drove home Sunday night ... all of a sudden the engine started to hesitate, felt like the throttle body was stuck. I tried to give it some gas, but nothing. Then the revs just fell til the car stalled.

I had it towed to my Acura dealership. The belt broke.

I had the belt on for roughly 30,000 miles w/ Toda "B" cams.

My tech guy said some valves were bent ... don't know how many for sure til the head is removed, which I'm not having them do ... haha.

Moral of the story ... change your belt VERY frequent with high lift cams.

I think I may go turbo. New project.

 

Or go with a Power Enterprises or Spoon timing belt.

I myself have the Spoon.

 

Why do some people have this happen? It only seems to be with Spec Bs, ive never heard of this with JUNs, what causes this??

 

This can happen with any highlift cam. It's been known that if you are running Toda Spec B's or C's you should change the timing belt every 25-30k even if it shows no wear. It's probably best to do it with JUN Cams as well.

Add another to Toda b belt breakers list. Back when this happened to me everyone slammed me "you put them in wrong". I can name at least 5 others now just from Honda-tech alone. I bent all 16 also. You should look into getting one of these for the rebuild.

 

I wonder if theres anyone who makes a timing chain conversion? Or do chins suck at high RPMS? I think the RSX and S2K motors have timing chains.

 

Aren't the valve springs the concern, not just high-lift cams? Increased pressure on the t-belt causing early fatigue?

 

don't worry I am having problems too.. damn lemons.

 

belt changed twice already here, 45K on the ticker...............

 

much cheaper than a set of valves too...

 

Would a chain break after so many x-miles with high lift cams? Someone should develop a belt to chain conversion.

 

Stiff valve springs compund the problem, but cams with high lift primary lobes, like Toda's, accelerate the wear effect. The primaries on the Spec B's and C's are almost the same length and duration as the high lift secondaries on the stock R cams. So as far as your valve-train is concerned, you're driving around in VTEC all the time.

I lost track of how many valve springs, valves, and valve guides I busted with my B's. After two timing belts and all the associated damage I had had enough.

I'll take a stock cammed 2.0L any day.

how much those belt cost and spoon belt cost? TIA

 

I think the Spoon goes for about 250, not sure on the Power Enterprise belt.

 

I'm through with N/A ... Toda cams are nice and all ... but it's true what others say. There huge cams that put a lot of stress on the engine (i.e. timing belt).

I think I'm just gonna drop in some 9.5 forged pistons, Eagle rods, block guard ... STOCK GSR head with my Skunk2 manifold and get a DragIII setup (w/ upgraded parts) with a Hondada 2b and fully tuned. Should easily put out 260WHP ...

 

Mike...I saw your springs and valves last Friday, and all I can say is that those damn things are HUGE beefy springs...
Hope everything is going well.

I got mine from Leo @ http://www.cj-motorsports.com/ for 160 shipped.

 

spoon is about $175-190

Those prices from Eric Bauer's site don't include shipping/customs fees. Those have to be taken in account. But that is MSRP in Japan converted to dollars. He also is not a seller.

 

do they make one for B18C1? or does the ITR timing belt will work fine, because GSR's head is a bit longer, don't you guys think is gonna be a problem? TIA

 

Yeah, my timing belt stripped out (on the crank pulley) with about 18k miles on the belt. The car just died at idle as I tried to get rolling and wouldn't restart. Some oil had leaked out and collected at the bottom of the timing belt cover, though. Bent all 16 valves.... cost me $1200 to get it fixed.
