Built HR *Broken Cam*
Built HR *Broken Cam*
Some may and some may not know, but my possessed Z broke a camshaft. Don't ask how I do not know. I have talked to several well knowledge sources and I have my ideas, but will not speculate till the motors stripped down.
Ill keep some updated info in this thread as progress is made at
WIN Motorsportz (In affiliation with Redline Design)
Ill keep updated pictures and answer questions if anyone has any.
Backround on this motor. Built by Engine Lab/S&R Performance
CP Pistons
BC Springs and Retainers
5 Angle Valve Job
GTM H Beam Rods
HKS Head Gaskets
One of a kind Closed Deck Block
ARP Head Bolts
Everything Cryo Treated
Factory Cams(When the motor was built none were available)
HKS Twins with Forge Motorsports Wastegate's
--------------------------------------------------------------------
This car started out well over a year ago after being one of the very few stock block HR's to Blow. It snapped a rod in two at 500whp in less than 3k miles. The motor was then built at Engine lab and S&R Performance. Since has had many issues. Leaking turbo lines, boost leaks, ecu failures, sensor failures, wiring failuers. Ill be honest im surprised I still own a boosted Z after the headaches and money I have spent on this vehicle. Then everything started to work out I put about 7k miles on this motor then one day...Snap. The car sounded like a V8 after looking into it the Intake valves on the Bank 2(driver side) were not opening. Took the Cam cover off to find the pully still tight. You can turn the motor over with the bolt that goes through the center of the cam gear, but the cam does not rotate. So only possibility broken cam. If the key had broke then turning the bolt in the center would still make the cam rotate if not atleast move, but no such luck. So motors now out at WIN Motorsportz and should start to be stripped down here in the next week. I will try to keep this thread updated.

Well I haven't seen a down side yet. Car runs at the same temps it did prior to it being done. All in all I would say it can't hurt, but who knows if it helps anything.
its actually a block guard like hondas have been using for years....

that being an example. It just closes off the top of the block. So not a fully closed deck... no cement poured around the edges or anything.. lol.
More pics of the build and past.
Piston after the stock block blew up.... Any guesses what happened .... ?
Before Block guards during build....
After block guards were added and begining stages of the finishing... Work dont by Engine Lab.
Right before polishing....
