1.8t in 4kq

Wed May 15 17:01:50 EDT 2002

Said it before, the 550 HP figure comes from Dahlback Racing at http://www.audituning.com/english/main.asp The upgrade to the engine costs around $3,000 installed from what I was told. You are right, no replacement for displacement unless you happen to have a newer higher tech low displacement engine against an older design high displacement. Saying it's all about swept volume is nuts, how come a Lotus Esprit turbo 4 is faster than a camero with a 305? The old Chevy 305 is MUCH larger...

But, that's not really the point, the guy wanted to know whether it can be done, not whether we like the 1.8T better than a 20VT, so let's get this thread back on track...

These figures are grossly overinflated; you also seem to have
interchanged torque and HP in one case.  Go check out the APR and
Hoppen websites for proper figures, but they're briefly summarized
here.

An APR "chip only" puts you at 200hp, 245 ft-lb.  Any more requires a
turbo change.  Congrats, you've now surpassed an unchipped 3B in
torque slightly, but you're 17 short in the HP department.

As for "stage 3 kits", Try 280hp with a turbo from APR; further
mods(III+) get you just over 300hp.  They don't list any other
options.  The III+ will give you about 30 more hp and about 30 more
ft lb of torque than a chip-only 3B.

  MTM's "chip only" is 187; chip+turbo stage 1+ is 193, stage 2 is
210, stage 3 is 240.  I'm semi-curious why APR seems to be getting
drastically higher numbers compared to MTM.  I wonder if MTM is
measuring at-wheel and APR is measuring at-flywheel.  Who knows, they
don't even put units on their charts :-)

I have no idea where you got "550 hp"; MTM's tuned RS4(which, of
course, is not 1.8t based) is around 510 hp.

I remember reading about the bimoto TT, which has around 500-600hp
per engine...but those engines are massively modified down to the
most basic specifications and probably have tens of thousands of
dollars of work in them.

The difference is that for $500-600, you've power+torque levels it
would take an 1.8t owner about $4,000 to match.

The 3B engine owner laughs, spends half as much($2000-2500) and gets
an RS2 conversion with at least 30+ hp over APR's stage III+.

What was that about "economical"?

As the old saying goes, there's no replacement...for displacement.
