4agze internals?

[trdee]

And I was running 20psi on my 4agte revving to 7750rpm

Same engine was also involved in four engine bay fires, two BIG oil pressure loss events (but I shut the engine down immediately in both instances), 3 years of heavy abuse at the track running 11psi through the supercharger. And when i originally bought the engine, it came out of a halfcut which had been clearly raced and rolled previously....

They are strong nuggets. No doubt about it. Change fluids regularly, make sure it has a good tune, and you wont have issues..

Not indestructible though
Stock as a rock 4A bottom ends will do 8200rpm without issue
