[QB]J6R is the 2 litre atmo engine that came in all Fuego's imported to Australia. I say its same as J7R except for carbie vs turbo/injection of J7R. But im not sure of what internals they have in common. I predict that the J7R, being a turbo motor should have a stronger bottom end than the atmo J6R (dont know for sure) plus obviously compression for J7R has been reduced somehow.
J6R - 2.0 Fuego Oz spec, J7T R21 & R25 unleaded 2.2 Renix injection (V. nice) and the juicy one J7R 2.0 as fitted to R21 Turbo (especially yummy in Quadra format). All 2.0's are the same bottom end - just modified head for lower compression for turbo. 2.2 simply use a longer throw crank.
The best engine is to use the J7T 2.2 botton end, J7R turbo system, and the 12 valve head fitted to R21 TXI. Stupidly fast in a Fuego!!!! Might have to fit the R21 Quadra driveline to get the power down!!
Cant remember the link, but I've seen pics of a black Fuego in Germany with the J7R turbo fitted. Solves gearbox problem by fitting R21 Turbo gearbox - easy. If you have friends in Europe willing to send you an R21 turbo engine and gearbox, I'll beating on your door fot contacts!!
