We will try to keep this list updated but if you do not see your engine listed here please ask!  We can  do custom stroker or knife-edge crank designs.  We can provide plastic templates for initial fitting and adjustment.

 

We have included some representative pictures of the scrapers we make.  If you would like to see a picture of a particular scraper please ask -- we would be more than happy to send one through.

 

Our standard scrapers cost $59.95 unless noted.  When available (please enquire) our zero-clearance TeflonŽ scrapers run an additional $100.00 to the cost of the standard steel scraper unless noted.

 

Remember, your vehicle may have an engine made by a different manufacturer so check both product lines.  If you are still unsure, please contact us.

------------------------

SR20  (DE, DET, etc.) Note: If you have a SR16VE or SR20VE, SR20VET -- skip the section below discussing the girdle unless you plan on adding the factory girdle to your engine.

There are a number of options for the SR20 engine but the very first thing you must determine is whether your engine has a narrow or wide block.

The narrow block was designed first and is used in a number of applications.  If the vehicle you obtained the engine from has AWD then it is almost certain you have a narrow block -- the narrow block allows greater room for the transaxle.

Here are some pictures to help you determine what block you have; click on the pictures to make them larger:

Narrow:

 

Wide:

Below are some oil pan pictures.  Do not pay attention to the lower steel part and do not expect your pan to look exactly like any of the pans -- look at the upper alloy section that bolts to the engine block itself.  You can see that the one on the right is visibly narrower than the one in the middle and left:

 

Now, in both the narrow or wide engines it is possible to have a crank scraper with directional screening windage tray that bolts into the girdle. 

Both layers nestle within the existing main bearing girdle and attach to the existing mounting points for the factory 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. 

This part costs $109.95.

Here are some pictures:

The picture below shows the scraper and tray from the interior of the girdle.

From the top ...

Underneath ...

There is an option with the girdle scraper ...

The flow of air in the fourth piston bay is highly obstructed by a cylindrical indentation in the stock sump.  This indentation is designed to allow access to torque converter bolts.   It is highly desirable to remove this inward facing bulge if you are running a manual transmission.   This means you will have to take the sump into a welding shop that is experienced with working on automobile parts this large.

Bulge:  

Example of a removed bulge:

If you decide to do this modification we can supply you with a precut piece of aluminum that will assist the shop and we can expand the scraper and windage tray screening to cover this area.  This would add $35.00 to the cost of the girdle scraper and windage screen. 

Here are pictures of the resulting parts:

This picture shows the screening and scraper without the relieved openings for a pickup tube -- this is for a dry sump setup or for those variations of the engine that have the pickup support strut attached to the side of the girdle rather than the interior.  If you are unsure where your pickup strut mounts then simply order the standard version.

If you have any questions about your application -- please ask.

The next option for the SR20 engines is again for both the wide and narrow versions.  This option is designed to work with the girdle scraper and tray.

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.  The frame mounts on top of the main bearing caps underneath the girdle.

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 $299.95; add $100 for TeflonŽ if you have a wide block.

Teflon version for wide block

If you do not want the baffle assembly AND you have a wide block then it is possible to get a steel scraper ($59.95) or a Teflon bladed scraper ($159.95) alone.  These scrapers are ideal for the VE versions of the motor which have a wide block and no girdle.

We also have versions of this scraper for knife-edged cranks.  Please enquire for more information.  Here is an example:

 

--------------------------------------------------------

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:

   

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; the separate piece by the flywheel accomplishes this:

We have made many custom scrapers and trays for these engines. 

KA24e tray and dual scraper; the tray seen below is custom as it includes the area at the rear of the pan where the indent has been bumped out:

This picture shows how a stock KA24E tray fits within the pan; it works with the existing structure:

----------------------------------------------------

 

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

 

There are TeflonŽ versions of these scrapers available for the upstroke scraper.

 Upstroke L28 scraper installed:     

-----------------------------------------

VG30 series dual scrapers.  Please specify whether you have a VG30E  (ET, etc.) or VG30DE (DET, DETT, etc.)  variant.   The patterns are different in the front cover area (oil pump) as well as on the side where the pickup tube (DE) passes.  $114.95   Teflon version: $214.95

 

Above: the dual scraper on the VG30DE(TT)

Below: VG30E dual scraper

Important! The VG30DETT pan (for example) has an inward bulge just over the kickout.  This is to allow technicians access to the torque converter bolts as with the SR20, KA24DE, QR25DE, RB26DETT etc.

This bulge creates a disturbance in the windage flow and should ideally be bumped out if you are not running an automatic transmission.  The VG30DETT downstroke scraper is supplied with a screening panel for that area that will fit only if you bump out the bulge.  Otherwise you will need to simply trim off the last panel.

 

 

 

-------------------------------

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):

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).
