newbie questions
i've searched
does the oil squirters for the pistons make that much of a difference, can't you just put those components as a mod?
why do people swap their engine when they have the mighty 2jz in NA form?

Guys may tell you otherwise, I feel they're very usefull in cooling the piston, but big hp has been made without them. Yes, you can modify the GE block for oil squirters, but most don't bother since a new GTE shortblock is so reasonably priced.

Is the engine swap REALLY worth the time, effort, and money as opposed to drilling?

I'm with Lex on this one. Oil squirters *are* that important.
No one has put 1k crank hp on a stock NA short block, but it's been done on a stock TT short block which is proof enough for me.
You can't under estimate pulling heat out of the piston. It increases the strength of the piston due to lower operating temperatures. The TT piston also benefits from an oil gallery that is cast into the top of the piston just under the "dish". The oil enters one hole and exits another hole diameterically opposed from the entry point. Installing squirters on the NA shortblock probably won't hurt, but you'll only get the full benefit if you have TT pistons to go along with the squirters. Otherwise, you'll just end up squirting oil onto the NA piston wrist pin.
Methanol/water injection in the intake air has been proposed as an alternative to oil cooled pistons, but until someone puts 1k hp with meth injection only on an NA shortblock, I'm not a believer. For those of us running high boost on an NA motor, however, it's the only option right now.

You make a good point, but honestly though I don't really think many people here will be trying to achieve 1k at the crank. I'd say that if you were doing upto like 800 hp or less you would be ok using the na block and save alot of time and money on the swap.

NA being the 1JZ or 2JZ? Technically neither one are turboed in the short-block form, hence I'm a wee bit confused... lol. Where did you get it??

Correct me if I'm wrong, but the word I'm hearing is that oil squirters become detrimental at high high horsepower. At 2000 degrees, oil begins to cook against the walls.

Get to 700rwhp then worry about oil squirters.

...Get to 700rwhp then worry about oil squirters.
... I wouldn't trust any off-the-shelf engine mechanic to mimic a carbon copy of the Toyota assembly line's squirter specs, but maybe I misunderstand the difficulty of the job.
