lookforjoe Posted April 20, 2011 Report Share Posted April 20, 2011 Installed the newer head & Enem Cams today (started yesterday, but had to remove the cams twice due to issues with the reference markers/ Volvo locking tool.These cams cannot be locked from the rear as with Volvo cams, so I had to improvise to get the hubs torqued to 120Nm.reference markers indicate 1.5mm INT lift 1.2mm EXH lift @ true TDCIAT bung added to my modded ME7 NA manifoldHave to wrap up the ancillary install & get all the plumbing back in place. Has to wait until Thurs, have Inlaws visiting at the moment Link to comment Share on other sites More sharing options...
Scandia1568908312 Posted April 20, 2011 Report Share Posted April 20, 2011 Nice work Joe. . . . .Did Enem do a custom grind for you ? What are you expecting to benefit the most from the swap ? .......Dave Link to comment Share on other sites More sharing options...
lookforjoe Posted April 20, 2011 Author Report Share Posted April 20, 2011 Nice work Joe. . . . .Did Enem do a custom grind for you ? What are you expecting to benefit the most from the swap ? .......DaveNot custom grind, these are their Y21 dual VVT cams, 264/110/9.6/0.8 cam set. It's been so long since I originally researched & investigated cam options, & ordered these, that I can't recall the specific performance gains.My main goal is to improve breathing to take advantage of the turbo I'm running. I seem to have hit several walls with the stock (-'98) head & intake, and have not been able to get the level of gains one might expect from the turbo & levels of boost I have been working with. I will dyno this @ Carlisle in May, so I have some time to play with the cam timing & the tune to see what I can do with it. 312WHP was my best (FWD mode) number last May, so I'm hoping for AT LEAST 350WHP this year!! Seriously, though - the main goal is get have a truly useful powerband, not a setup that has to be flogged to death & high rpms' to get power out of it.I'm looking forward to seeing how this thing runs tomorrow!!

Scandia1568908312 Posted April 20, 2011 Report Share Posted April 20, 2011 Gotcha. . . . .Suck's when you put as much time & effort into something as you have & hit a wall that's unexpected. Hope everything work's out. waiting for your update........Dave Link to comment Share on other sites More sharing options...
Big Will Posted April 20, 2011 Report Share Posted April 20, 2011 Cool install! Hope it makes a significant difference in driveability. Link to comment Share on other sites More sharing options...
lookforjoe Posted April 23, 2011 Author Report Share Posted April 23, 2011 Warmed the engine up, checked fluids. drove around the block, low rpms, 1-2nd gears watching the vacuum, as it is markedly different with the high lift cams. Engine died as I came over the crest of a small hill. Pulled over, popped the timing cover, bumped motor over in gear to check marks. Crank & exhaust reference markers OK, intake gear had spun in the hub (CC, which should retard & increase clearance). Loosened the three bolts, rotated the cam back to center. Cranked it over, definitely has no compression.Pushed the car the block home.All intake valves bentAll pistons are marked in the valve recesstwo of the three threaded holes in the intake hub are stripped - I tried gently snugging them (they are only M6), and could tell that they weren't tightening.Still haven't figured out how I ended up with valve to piston contact - I did rotate the crank 4 revolutions before I even THOUGHT about starting the engine, to be sure that there was no interference. Obviously something was amiss.I'm going to add a second oil filler neck, and remove the baffle from the existing, so I can check actual lift on #3 cyl, instead of relying on the reference slots on the back of the cams. The head is back at the machine shop, he's optimistic that he can just change the valves, the seats don't look damaged - the guides he will check when the valves are out.

Big Will Posted April 23, 2011 Report Share Posted April 23, 2011 That's not a good day - hoping for the best case scenario. Link to comment Share on other sites More sharing options...
lookforjoe Posted April 23, 2011 Author Report Share Posted April 23, 2011 Added to second filler neck - for checking valve lift on #3Picked up the 10 new valves yesterday afternoon, so I'll drop those & the cam cover off at the machine shop on Monday Link to comment Share on other sites More sharing options...
lookforjoe Posted April 23, 2011 Author Report Share Posted April 23, 2011 This also arrived yesterday from KalmarUnion (UK) - so that has to be planned for installation Link to comment Share on other sites More sharing options...

Scandia1568908312 Posted April 24, 2011 Report Share Posted April 24, 2011 Ment to ask you over on VS, why not go with Viva's SM flywheel. I thought they were only 600. . . .and another member from SS PM'd me a link to get it for 540 from Ultrarev with free shipping. . . . .? ?.........Dave Link to comment Share on other sites More sharing options...

lookforjoe Posted April 24, 2011 Author Report Share Posted April 24, 2011 That brings tears to my eyesThe pistons come with recesses, I'm not sure it's that bad. The motor was running @ low rpms when it happened. I'm hoping for the best, I'm not dropping the bottom end in my driveway I didn't know VIVA had a SM replacement for DM setup (uses existing S60R DM Clutch) - that's what this is - not a SM replacement for SM stock.

Moot point for me, but if one is available this side of the pond, it would be good to know. Link to comment Share on other sites More sharing options...
