Sold! Thanks prime

I bought the setup that Titaniumdave made, ran it for a couple years then the car sat for a long time. I am now selling it after starting to drive the car again and switching to the SOS twin turbo kit. You can search this thread for the story of the original build: intercooled 2.3 L...

Whipple does sell pulleys and they have a selection of them on their shelf. They are pretty reasonably priced (<$100 shipped). BUT they will just ask you "what kit is it for" and since the NSX kit wasn't one of theirs, they can't just ask you what diameter you need and be done with it. There...

That would require removal / disassembling the motor. Given that the issue is fixed, and that any blockage is immediately upstream of the filter screen on the spool valve inlet, I'm going to let the sleeping dog lie. - C

Unfortunately, no. The motor has been gone through a couple times; it's the mystery of the ages as to what is really going on. There's only a short length of passage that I bypassed, and it works now... so there's obviously something in there or could also be an issue where the passage goes...

Fixed the VTEC problem by running an external oil feed from the rear head to the front head. Now having a 3.75" pulley made to install before going back and finishing the tune. Car does run very well with the VIPEC; feels like a stock EMS to me.

Well, the bypass worked and now both spool valves are showing ~70psi in VTEC. Ended up pulling the two 16mm x 1.5 allen galley plugs in the heads (located on the flywheel end of the motor by the spool valves) and replacing them with AN fittings connected by -6 hose. Let me tell you how much...

After taking the cam pipes and front cam holder off (thanks Larry B for the tip about removing one cam pipe at a time and bolting down the other cam holders with washers), the results were..... puzzling. Dowel and O-ring were in place in the center of the cam holder. Rocker shaft restrictors...

Not quite sure why your timing would impact your VTEC engagement, but glad you got it sorted out nonetheless. Mine is a mysterious issue with the oil supply to the spool valve at the front head. After much investigation, I have come to the conclusion that it is some blockage in the oil...

I had debated whether or not to do this when modifying the snout for the new throttle body. In the end I decided it wasn't worth the changes it would require to the bypass valve routing, the airbox, hose routing, etc. We just made sure the inlet had a greater cross sectional area than the...

Probably should change the title of the thread to "Worlds slowest 2.3l whipple SC build"... Had a bit of a delay waiting for tuning, but got it on the dyno and got it up to just over 400hp @ 11psi before discovering that one of the cylinder banks wasn't going to the high cam on VTEC...

Okay, I'm digging into it Friday, we'll see what we uncover once we get in there....

Yes, not removing the belts would pretty much make my day. So, I'll try the "one cam pipe at a time" approach with putting the bolts back in with washers. Do I need to rotate the engine to try to find a place where the cams are more unloaded from the valve springs?

Thanks Angus! At first my guess was a VTEC pin, and I expected to see oil pouring out from between a set of rockers when I did the pressure test. When it all came out the VTEC relief hole.... I knew it was probably something else. I'll check out dowel pin and let you know what I find...

First - thank you for the reply, very helpful! I doubt I'll find anything in the pan as this motor has been completely rebuilt and the problem was there before the rebuild, we suspect. I think the pin is long gone. So... am I correct in thinking I can leave the cams in place and just remove...
