I've heard that getting a n/a supra is not worth it because the engine cannot handle as much as the twin turbo.(mainly the reason why im looking for a n/a is because of the insurance) i was wondering is the n/a engine CAN be turbocharged or not. is it worth it? and any info that i am not aware of would be useful. thank you.
The 2jz-ge (non-turbo, n/a) engine, after 'turboing' it of course, can handle about 600rwhp* through a manual transmission (using race fuel, of course) before it needs to be internally modded. Although this isn't as much as the 2jz-gte's capability (850rwhp through the 6spd, using race fuel), 600rwhp* is usually PLENTY of power for most applications. The n/a can be turbocharged, and you could say that the $ and effort is worth it, because the horsepower can be increased reliably, BUT this depends HEAVILY upon your application: roadrace, drift, autocross, drag, street, daily driver, highway rolls, etc. For most applications, there's far more than horsepower alone to the overall performance equation. The mkiv TT is a significantly more capable overall sportscar than the n/a, in the areas of braking and suspension, and horsepower holding capabilities in the transmission and differential. So again, is it "worth it" to turbocharge the engine? Yep. Will you end up with a car that performs overall like a TT if that's all you do? Nope. Would it be less expensive overall to simply wait and save up for a TT if you do actually want/need to end up with the full performance package of the TT? Yep.

*Note: This 600rwhp figure can go up to about 700rwhp through a manual transmission, if you swap the 2jz-ge's head gasket for a thicker one (to reduce the CR).

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
