low end garbage!! 86.5 N.A.

[bugz66]

ok,well my low end and mid range torque sucks.trying go around the twistys with great suspension set up but no low end,around 2000 - 3500 rpms.
engine is stock NA 5 speed, intake, gutted cat, 2.5 exhaust.
3.73 lsd
255/35/18 tires/rims
tuned up and timing in spec.10-12 deg

all i have is high end,pulls hard!
any suggestions on what it could be?????

thanks

Why do you have a turbo rear end? You need to get the engine into it power band just shift to a lower gear. When I cruz big sur I never drop below 3500 rpm.

Try being in the right gear?

 

[bugz66]

well its kinda hard to shift to first while going 30 - 45 mph.
im usually in second while going though some tight corners,but if rpms drop
no low end at all.

turbooooo.... And get a 4.30 rear end, will help keep the rpms high

Heel toe is your friend, plus your gear ratio isn't helping (there's a reason NA's came with the 4.30's)

ACIS working?

 

[RazoE]

definitely switch back to a 4.3...

 

[bioskyline]

the 3.73 is to high of rear end gears. 3.73 is geat for a high speed track, like a nascar oval, but for what your doing go back to the 4.30

 

[Moy]

you could even benefit from a 3.91, but yes 3.73 is WAY to high a rear end gear for N/A

 

[bugz66]

yea i was hoping it wasnt the 3.73 LSD but i think i will get a 4.30 LSD soon.
thanks for the advice and not hating(like some honda fools)

3.0L/200 crank hp/3600 lb car and it now has tall GTE diff gears and you wonder why it's slow :runaway:

x2 on ACIS

When i had the 3.91 in my old n/a car is was awesome to go through canyons staying between 3-4 and never bogging.

 

[CT26smoker]

How many NA can even pull 85% of max rpm with 3.7 or even 3.9 rear ends ?
Not many......
There are hp-mph conversions all over the net.
A wishful 200hp can not pull a car as big as a MkIII to 185 mph.

And learn to shift, or fix your syncros so that you can,
Then gear lower, and go faster.

i have the turbo rear end in my n/a i never saw it as a problem o.0.

 

[hvyman]

Which 1? 3.91 or 373? 3.91 is not that big of a deal.

 

[xzeror]

no idea, i just remember someone posted a chart showing rpms with diff differentials and transmissions. I verified i had the r154 with one of the turbo rear ends. Does anyone have that link or chart?

 

[hvyman]

The r154 and w58 have different gearing.

I got the 3.73 LSD in my n/a as well and have no problem. Great for highway cruzing at 3k.

your acis is broken.. mine does the same crap teerible low end and then amazing top end... i also have the na LSD
