JUST bought my new to me '06 IX SSL a week ago. Full bolt ons, ported head and exh mani, FP Black, catch can...nice stock block power.
4/28/15 - I take her to a local guy's house/shop to get a VBand welded onto a stock cat and installed, for inspection purposes.
4/30/15 - Go to take her to get tags/title/inspection. Crank her over...she starts...chugs like a dying tugboat (worse than usual, cold start is horrid...tune needed adjusting)...then died within a minute. Refused to restart, sounded very angry from the bowels of the motor. Heavy knocking/tapping. Battery works, fuses are good, full tank of gas. Didn't have a second set of hands to check fuel pump voltage or spark plug firing. Pulled upper timing belt cover off and saw the belt nearly falling off (see pic below). At that point I know I'm screwed...head is probably trashed. Got her flat bedded to my friend's shop to get her diagnosed for sure and start the teardown. He pulled plugs to check easy things first...and saw they were donskies. Dropped a camera down the plug port and saw broken bits of valve on the piston heads. At THIS point we know it's really bad...but until Monday when the head comes off we don't exactly know HOW bad....
I think the cause was a failed tensioner/pump causing timing to jump at startup. Just a theory. Mechanic thinks high EGTs (he's obsessive about them, old school) dropped the valves and jumped timing/killed tensioner. That makes less sense to me since the belt is obviously a thicker kevlar belt. Seems more logical that the thicker belt killed the tensioner or the tensioner was bad to begin with (changed 15k miles ago, two owners ago). I can't blame the guy I bought her from, from where I sit this was a freak accident/time bomb.
At this point (early, I know), I'm assuming the head is done (ported stock head, though HOW ported I don't know), pistons done, and probably some good scarring on the cylinder walls. Rods are probably good, but who cares they were probably going to get replaced anyway. I had been planning a build next spring...just gonna do it early I guess.
The Plan:
-MAP 2.1L stroker block
-MAP Stage 5 head
-FIC 2150 High Z injectors
-Buschur double pumper
-STM ported intake manifold
-Buschur 65mm throttle body
...Mated to what I have now:
-JB FP Black (rebuilt by FP 6 months ago)
-Toxic Fab exhaust manifold
-Buschur DP
-Buschur FMIC
-Buschur UICP/LICP
-Buschur 4" intake with Perrin filter
-Custom catch can setup with battery relocate
-GSC S2 cams
-built Sheptrans/tcase
I think with this plan I'll find the limits of 93oct well before the block/head/turbo. Thoughts? Yes I'm sad, but strangely calm about it...this isn't my first Evo but definitely my first motor build. I know it won't be easy or quick.
My questions revolve around the options on the Head and injectors...not sure what I need or should get. Not sure if there's anything else I need to get. Had also considered the new SS housing for the Black, but not really feeling a new downpipe and wastegate.
