I would imagine the issue is ATF pressure from the extra 1,000 rpm there
is to play with,
nothing to do with hp and torque going through the trans.
I have not had a problem with stock ATF coolers failing, though I have
sold two good used ones.
Iwould agree, 'not as silky smooth' ..but the extra hp , throttle
response, fuel milage, and more rpm to play with make it worthwhile.
subaru conversions can be less refined feeling than waterboxer engines.
Sometimes the exhaust is noisier, but it doesn't have to be. I use a
stock 2.1 muffler and those work just fine.
Sometimes there is noise from the power steering system , but usually I
don't have a problem with that much.
I have seen several conversions with K & N type air filters..and those
don't subdue inductior roar much at all,
but a stock subaru air box, or KEP's air box works nicely.
Resonance ....possibly ...
the shifter shouldn't buzz ....I'd lookinto that carefully .
Subaru engines arefar easier to work on in a Vanagon than in a subaru car.
Especially if the back end is lowered down some.
OTOH, there's no timing belt to think about ever in a waterboxer engine.
A subaru conversion is rewarding, quite, let's say.
the power curve is very nicely matched to a vanagon and vanagon gearing..
nice wide power band, and there's more of it, plus 1,000 more rpm to
play with.
Is it better to cruise at 70ish at 4,000 rpm with a 5,000 rpm max engine ..
or with a 6,000 rpm max engine ?
the later of course.
