Aha! Thank you. For some reason I was not thinking about the right
Mine is a 53J 1R, listed as "Unknown" and most think it's a JDM engine but some
think it's a USDM engine. Yay for confusion!
Apparently the only sure way to tell is to pull the head and see if
the pistons are
dished or flat.
My '91 SE-R is a 53J 6L Which isn't listed at all, but I know it's
original. It certainly
had more oomph than my 93 did, which makes sense with earlier vs. later cams.
The engine in the G20 certainly has a lot more low-end torque than the SE-R, but
then the SE-R at this point has a header (with 2" collector) and a
very open 2.5"
exhaust. The G has a header (with 2.5" collector) and an OEM-style
So some of that may be exhaust gas velocities and it's hard to do
I have to say I'm loving the G. The interior was ratty, but I got a
full set of seats from
a junker that were in beautiful shape for $44 for both fronts and
rear. E-bay header
and Bosal exhaust to replace all the pieces falling off the car and
it's decently quiet.
Got a set of manual seat belts to convert over to when I get the time.
Suspension has a million clunks and the engine mounts are *shot* like
I've never seen,
but that's all little stuff to track down as time goes on.
Two weeks and the SE-R runs for the last time this season, and heads into the
garage to complete the cage, but I'll get to keep driving the G, and
that makes me
