No it just takes a lil effort

Very quick answer to your question:

NA-T: Very good option if your motor is in good shape, do a compression test to see where it sits. The 2JZ block is strong enough to handle gobs of power, and the head flows very well.

JDM: You're taking a big risk with a JDM motor, consensus is that these things are beat to hell overseas and then shipped here. Also, once done you'll still be TT and wishing for single turbo. Also the more expensive option, but you'll have oil squirters yayyy!!!

If your SC is your daily driver, may I recommend buying a relatively low mileage 2JZGE (easily for less than $500), and then turbo that engine, replace all the seals/timing belt etc., then swap that in

The jdm engine is definetly the expensive route, i see cheaper 2js going for around 2k but the majority of compression tested warrantied engines seem to be 2500-4k and good luck if you want a 6 speed.
Im sure some will argue the jdm swap is better but this is simply my experience

so figure

2500-4k jdm gte engine
????- Install cost ( very large variable)
going single turbo 1-2k (cause most people go single shortly thereafter anyways)
=3500-6k+

Pros: OEM reliability and quality workmanship
No fabrication other than harness work and IC piping.
Having a cool 2j swap in your car.

Cons: who really knows how many miles it has??
Turbos will need to be replaced eventually one way or another unless usdm
Increased parts and labor cost
vs

1800ish (xs power kit or diy)
150-500 Engine management (gte ecu-map ecu etc)
?????-install cost.
tt HG and arp studs- 160-200
IC piping- 200
Injectors 200
= 2600 ish (plus if you pay someone to install or diy)

Pros: Dont have to pull engine
If your engine is well taken care of you have peace of mind
Immediately going single
Parts are cheaper

Cons: Troubleshooting issues that will arise
Requires a bit more custom work and "know-how"
Requires more tuning


Sorry for the long post, All in all for the price na-t is the most cost effective route and with the extra money save over going GTE you could build your whole bottom end and slap a new head on it too.
I imagine even with my built bottom end and new head on my na-t im still way lower budget and just as fast as any GTE swapped car.
