Be selective when picking out the blower kit also. A bigger blower can always be toned down with pulley sizes. The bigger cc blower will allow more scfm with less boost pressure. So you can actually add more hp with less boost. My cobra was at 21psi which could have done the same power at 15 psi with a bigger blower. Lower psi and more scfm will help with longevity. Lots of people producing big power with these cars and have never cracked a valve cover off. Wouldn't worry about oil pump gears honestly. If you turbo on the other hand, good luck with any and everything.
Makes sense.

Yep - that's what I plan to do with Marilyn. When I replace the engine, either I build her up all forged, or crate Aluminator. Then Whipple 2.9 or Kenne Belle.

I have the OEM OPG's now because, well, my blower (and most folks' blowers) are "kits" - and they're mostly bolt on for the most part. Take off the manifold, and injectors, and voila, you're 90% done. If I did a full BUILD, yes, I'd have swapped the OPG's and other parts.

It would be more than 20k. The Aluminator itself is about 10k and then you need the other little tidbits that go with it and then the new 2.9 supercharger and so on. Oh, and then there's install. Ask me how I know,........lol

hmmmmm
edit: something to think about... assume 25k for the complete rebuild. 25k is the price of a topped out Honda Civic or Toyota Corolla. So either I can get a Civic/Corolla ORRRRRRRRRRR an 800-900hp beast. hmmmmmmmmmmmmmmmmmmm

Oh I'm doing the install... me and my buddies. He has a shop, etc. I can guarantee I can I get the Aluminator for less than 10k. I also already started pricing a build of my current motor (bore, stroke, sleeved, forged, etc...) so for 20k, I can get that built, plus get the Whipple, injectors, fuel pump, etc. and Dyno Tune. I don't believe that included the upgraded clutch and driveshaft though. So, you're right, it's probably over 20k. But still. That's CHEAP compared to getting a 60-70k Shelby or ZL1.
hmmmmm

Where are you getting this Aluminator from? I searched and searched, but they are all about the same from place to place. About 10k, before three other key components you need to purchase separately. Or, are you talking about building your current engine to make it hold more power for less than 20K?
I was referring to this,

If you're doing the work and spending the $$ on FI, why not spend the few hundred more for the billet OPGs? Seems like it would be worth it just for the peace of mind. I know it's a PITA to do, and more work, but you've done 2/3 of the work by taking the chains off already anyway.

A loaded up Civic sounds better though! LOL

If I could do it all again, I would have just gone ahead and done the OPGs when I installed the blower.
I definitely don't want to take everything apart again just to do them though.

The failures are due to poor belt tensioner design. Then Harmonics. Then RPM's.

Most belt tensioners bottom out hard enough to bend them and break them off of their mounts. That takes CONSIDERABLE force. That force is transmitted to the crank snout. It's no different than hitting the balancer with a big hammer. Which goes right through the oil pump gears.

I've seen them break. And I've seen them break off the timing cover.
And even if they didn't break. How hard do you think you would need to hit a tensioner with a hammer to bend it? 5lb sledge? You've seen bent ones before right?
