420a n/t engine & 4g63 n/t engine question

[ecuella]

I'm trying to rebuild my engine and get a turbo and i been reading some of the threads on this page and many of them said that the 4g63 n/t engine can handle the turbo with no too many mods. my engine has 165000 miles on it and i was wondering if i can install parts of a 4g63 n/t to a 420a n/t.

I beg to differ!

You can use the exhaust manifold studs from the 4g63 in your 420a.

EDIT: Damned old threads.
