whats your opinion

[mad_dicer]

here is the deal. i have a 86.5 NA supra with 5 speed tranny.its now showing signs of a bad head gasket. what would you do. rebuild(or JDM) stock motor,do a 7mgte conversion, do a 1jz twin turbo conversion, or do a 2jz conversion?
i can easily get a 7mge JDM motor. i also know someone that has a lexus with a 2jz engine but has a blown auto tranny i could get for next to nothing.but if i went that route how hard is it to do a 7m to a 2jz conversion? so hit me with your input. links would rock to on write ups on conversions from 7mge to 7mgte and 7mge to 2jz(or 1jz).
thanks

also how hard would it be to a turbo conversion to a 2jz?

i think the question should be : how much money does this conversions cost
and how much money do u have

well here's my two cents
cuz ur going exactly where i was abotu a month ago

you can rebuild the engine with no problem
+side : you got a brand new engine, healthy and fesh
-side : unless u get is torqued and machined while ur rebuilding it
ur gonna go there again and take everything apart which means time and money

you can also, get a jdm 7mgte
+side : the engine is very available, and u get aftermarket support too
-side : its so hard getting them to pass emission

the 1jz conversion
+side : you get a twin turboed engine, good powerplant
-side : limited aftermarket support, and ur stuff is most likely going to have to be customized which mean, u guessed it money and time

the 2jz conversion
+side : yes it is the holy grail of toyota engines, any toyota car/truck
that has that engine with proper tuning will reign supreme
-side : the things costs so much, so hard finding a usdm 2jz, unless ur getting one from an aristo, it is not the same one from a supra
and if u get a jdm 2jz engine, ur going to run into the emissions problem too

but i really do think that ur best bet will be to find a usdm 7mgte engine
and work ur way up from there
if ur gonna get work done to an engine
why not the 7mgte, it is also a very powerful powerplant despite of the headgasket problem

plus a lot 1000hp supras are only using a singal turbo anyway

[Supra2NR]

yup, and even if u wanted twins,
i've heard of customized downpipes to accomodate twin turbos
so i believe its a win-win situation for u
