Give your BMW M3/325/525 a boost in horsepower and
efficiency!
Throttle body port and polish exchange service.
Fits 2.5l M50 E36 325
from 93-95, 93-95 525, and 95 M3
This auction is for
the exchange of your throttle body for a ported and polished throttle body.
We require a
functioning core for all our work and have two options for your convenience.
You can send your
original throttle body to us, and upon receipt, I will mail out the ported
version OR
You can pay us a
refundable core deposit of 49$ which will be returned through PayPal after
you ship your original throttle body back within 31 days.
After payment is
received for the eBay auction I will assume you would like to take advantage of
the core deposit unless otherwise noted. I will send an invoice through PayPal
to that same e-mail address and ship out the item when I receive payment.
Also please message
me if you would like information on custom porting work for any application!
Check
out the before and after pictures!
When you are looking to improve the
efficiency and performance of your engine one of the best ways to envision it is
like a big air pump. The more air you can move in and get out the more
efficient and powerful your engine will be. The problem is that through every
part of your engine there are restrictions that rob that power.
When porting these throttle bodies I
focus on removing the restrictions from this part of the engine giving your
snappier throttle response and increased power. The first side I focus on is
where the air hits coming from the air filter. I make sure that the air doesn’t
have to hit a step as in enters the throttle body. On the back side I match the
opening to the gasket so it has a perfectly smooth transition into the intake. I
also smooth out and sharp steps left by the machining process.
The main increase in flow through the
middle of throttle body comes from removing half of the throttle shaft and
countersinking the bolts connecting it into plate. By removing this restriction
a large increase in flow through the center section is created. Just like
installing a high flow air filter or free flowing exhaust this makes more power
by allowing the air to flow more easily through the engine.
When all of that work is done we
polish the inside surface to a mirror shine by gradually using finer and finer
grits so the air doesn’t hit any bumps that would cause turbulence. Finally we
sandblast and then paint the throttle body with black ceramic engine paint,
masking off the gasket areas for leak free performance and protecting the
electrical connectors. If you would like another color message us and we can accommodate
for an extra 10$
People usually report about the same
seat of the pants power increase as a cold air intake or free flow exhaust.
Your performance gain will also depend on how modified the rest of the car is,
it will be cumulative with and other mods you have done. The more you have done
the more your throttle body will be a bottle neck and the more opening it up
will help. The computer usually takes a bit to adapt to the increased flow just
as with any other bolt on modification.
