the A-series type oil front sump pan.
There is a replacement baffle for the sump but
with trap doors. The one in the pan measured had two
attachment points that were cracked and broken. The
replacement is made from heavier gauge steel. Also included is
an anti-surge baffle with a trap door leading to the rear of the
pan. Both of these baffles are to be welded or brazed into
place. $99.95

NEW!
Internal baffles and incorporated crank scraper for Nissan
SR20DE, SR20DET, SR20VE, SR20VET, SR16VE. These new parts are backwards
compatible with our crank scrapers and windage trays for the SR20 that sit
nestled in the girdle (see next product description in this section). The
versions for the SR16VE and SR20VE and SR20VET will look slightly different due
to the absence of a girdle and the partially counterweighted crank. There
is another point of variance and that is if your block is of the narrow or wide
form. The narrow form has both pan rails close to the girdle whereas the
wide form (pictured below) has one pan rail that is substantially further away.

The baffles above serve to direct draining oil from the head
away from the rotating assembly and to more smoothly guide windage past the
girdle arms. There is a crank scraper for the rod area incorporated into
the baffle. On wide blocks there is another scraper present on the
mounting frame. This scraper can be made into a TeflonŽ version if so
desired. Baffle assembly $249.95; add $100 for TeflonŽ if you have a wide
block.

To determine if you have a
wide or narrow block is very easy:

SR20
NEW! Please
be sure to read the last section -- there are now scrapers and
windage trays available for the SR20 with complete coverage for the
fourth piston bay. The SR20 design we make is actually a two-layer combination crank
scraper and windage tray. Both layers nestle within the
existing main bearing girdle and attach to the existing mounting
points for louvered pan baffles. The layer closest to the
rotating assembly has two scraper louvers for each of the first
three piston bays.
They are chisel edged with the second larger louvers being relief
cut so that it follows the contour of the factory rods and
counterweights (other rods can simply be adjusted for by grinding).
The louvers can be bent down or up to get very close tolerance fits.
The last piston bay has a single louver that is bolted to the
scraper. It is made to be removable so that it can be more
easily adjusted. The lower layer is a windage tray that has
offset oval drain ports so that the oil removed by the scraper can be
ejected but the stream of oil running underneath the tray to the sump will not be
directly in line with the louver openings. This makes it far
more difficult for the ejected and draining oil to be re-entrained into the
windage cloud. This tray also allows that layer of
draining oil (that allowed by the original cast sump floor) to be
even more isolated from the rotating assembly. This is a
continuation of the design philosophy seen in the SR20 which already
has extensive windage control features. The new windage tray
also slopes in the same manner as the sump floor it shields.
The SR20
already has a louvered plate that covers the forward two piston bays
so why is the scraper and windage tray offered here an improvement?
First, the chiseled scraper louvers in the first three bays approach the
rotating assembly much more closely and exactly. Second, the fourth
piston bay is highly obstructed by a cylindrical indentation in the stock sump
-- despite this a scraper louver is included forward of that inward
facing bulge. So now all four bays have active windage
control. Third, the incorporated windage tray further isolates
the entrained oil that is skimmed from the windage cloud as well as
the draining oil from other areas of the engine that passes along
the floor of the sump. In the stock engine this skimmed and
draining oil is still exposed to the rotating assembly.
The lower
scraper tray alone is available for $89.95; the combination scraper
tray and windage tray is available for $109.95.
We also have a
design for the RWD version of these engines. Two major
differences might help you to identify them: the oil pump pickup
attaches to the front edge of the girdle and the indentation in the
sump for access to the torque converter bolts is longer (see pics
below). Please be sure to mention if you have this type when
you order.

We have also added a version
for knife-edged cranks. Please enquire for more information.
NEW!
The louver openings in the scraper plate are now covered with
directional screening.

installed combination scraper and windage tray are below:

NEW!
Now available with complete
coverage for the fourth piston bay: scraper louvers and directional
screening. The hump in the pan providing access to torque
converter bolts needs to be removed by the owner or a local shop.
A formed piece of aluminum is provided to weld into this area to
close the pan. Obviously this modification is not recommended
if you are running an automatic transmission. Add $35.00
--------------------------------------------------------
KA24, KA24e, KA24de: There are dual scrapers available which
operate on both the up- and downstroke of the engine. $74.95
There are also windage trays available for the Ka24, KA24e and
KA24de engines. The windage tray is designed to work with the stock
pan -- the directional screening panels nest above areas not
previously shielded from windage. $169.95
Here is a picture of both the dual scraper and tray for a
KA24de installed:
New! As of 11-07, there is an updated KA24DE three piece dual
scraper design to make fitment easier while the engine is in the
car:

NEW! L6: L24, L26,
L28 -- Now there are dual scrapers for these engines that
operate on both the upstroke and downstroke. Only $74.95

We can do a pattern for the L28 Diesel (stroker)
but there is a plastic template charge of $35. You must fit
the template to your particular rotating assembly and then return
the pattern to us. There are TeflonŽ versions of these
scrapers available for the upstroke scraper.

NEW!
Scraper for the QR25DE: $59.95 in steel and $159.95 for a
TeflonŽ bladed version. We have versions for the earlier
partially counterweighted crank and the new fully counterweighted
crank. Will work with or without balance
shafts installed. It is totally compatible with the
JWT
balance shaft removal kit as well.

TeflonŽ version with baffle:

Fully counterweighted crank; steel and TeflonŽ
versions:

TeflonŽ frame installed (baffle with trap door
mentioned below is visible):

NEW!
Pan baffle with swinging trap door for the QR25DE. The key
weak spot in the alloy upper sump is the ability of the oil to move
out of the sump well and into the shallow end of the pan under
sustained hard turns to the right. This baffle raises the G
level that can be sustained in such turns and brings it more into
line with the performance of the pan in other maneuvers. This
baffle works with or without the balance shafts and will work with
the
JWT balance shafts removal kit if about 10 mm is removed from
the lower baffle plate edge nearest to it -- this is a very simple
modification that will allow the trap door to swing freely.
$59.95

NOTE: It is very
important to check to see if your upper aluminum pan matches the one
in the pictures. The door it fit specifically to the interior
of this pan. Baffles for other sumps are probably possible but
you would need to send us the sump (pics first, please).
