When I was running my 350z at 430whp...every time I got on her hard I prayed she would hold together..lol..

Built engines offer a piece of mind and allow you to have more fun vs. riding the ragged edge.

But really how much does a new engine cost vs all the built money? I understand building for 700 or 800 hp but at 600-650 I would rather just put the money in the bank and buy a new engine if something blew up. They really aren't that expensive.

How much is an OEM engine?

I can get a built one installed for that same $8k. I'll gladly go built just so I know it can handle the power.

Exactly. Why bother with another stock if you can build for same?

Because stock is stock. Tried, true, tested with tens of thousands of cars and millions upon millions in R&D. Sorry but bolting on something is one thing. You open the engine up and you could be headed for disaster.

Like I said, it would be one thing if you wanted to push the car past 650 in to the 700s but it seems like a silly thing to do for a power level that has proven to run just fine. Why not just replace the engine with something that comes stock at 650hp? Put a GT-R engine in it. I think it is safer than building.

My 2 cents.

So if you had your choice for the same money between a stock bottom end or forged bottom end you would pick stock?
