1ZZ or 2ZZ scraper
The design has multiple scrapers and
directional screening. Two principal angled scrapers both
remove the oil and impart a vector with guidance towards the
sump well. This is so oil can be transported across the engine
in opposition to the g-forces trying to make it pool up into
bays 3-4 -- the weak point of the OE wetsump design at
sustained 1G+. * The pickup as seen below has two 2mm spacers
under the strut and base which are included with the kit
(spacers are discussed below). The pickup is normally farther
away than it should be from the floor of the sump for
competition use. The net effect of the spacers and thickness of
the scraper plate is to lower the pickup by 2mm. Greater depth
is possible. A 2mm doubling plate is available and recommended
for the outside floor of the stock pan (mentioned below). This
will make it much more difficult for road debris or shunts to
push the floor of the pan up and close off the lowered oil
intake.

* This technique is not pulled from
the thin air. Ford, Porsche and Mercedes engineers have
all employed it in sump designs. Here are a couple
pictures of it employed in the modern Ford Cobra 4.6 pan:
Use of the 1ZZ pan is
recommended. It needs some slight relief at the windage tray
baffle due to the 2ZZ pickup being shifted over and of greater
outer diameter. Always check pickup to pan floor
clearances when using a pan for a different engine series --
just a common sense rule of thumb. If you are using the
stock 2ZZ pan, the OE windage tray is eliminated with use of
this kit.
Regarding Moroso alloy pans...
There are many people who have purchased the excellent Moroso
alloy pan for the 1ZZ or 2ZZ engine. We make a modified
windage tray insert with suspended directional screening for
use in this product. It can be used with or without our
scraper but of course we suggest using the scraper as well.
Please be sure to tell us if this is your plan as there is a
modified version of the scraper for use with the pan and/or
replacement insert. Insert price: $149.95
Note that there are two versions of the tray insert depending on
which version of Moroso pan you have.

1ZZ or 2ZZ pickup depth adjustment kit
This kit is to
check and increase, if necessary, the pickup depth on either the
Toyota 1ZZ or 2ZZ engine.
The kits are different because the
pickups are different so you must specify which one you need.
Remember that the kit you need is based on the block you have, not
the pan you are using. [Some people use the 1ZZ pan on the 2ZZ
for example.]
Why would I want
to do this?
For a pickup to operate optimally,
Ford Motorsports recommends .25" to .375" clearance from the pickup
opening to the floor of the pan. Less than this can cause
cavitation and loss of oil pressure and more than this can make it
more likely that your pickup will ingest air during certain severe
driving maneuvers. In mm those measurements are 6.35 to 9.525.
In checking the height of the
pickup opening from the floor of the pan we noted that, for example,
the 2ZZ pickup was 11.5mm up from the 2ZZ pan floor we had here and
13.5mm from the 1ZZ pan floor that we purchased new from the dealer
and this was not including any thickness at all for gasket material.
Important! It has been established that Toyota has used
different stampings over the years for the 1ZZ and 2ZZ pan so this
is something you need to check out on a case by case basis.
This kit consists
of 2 sets of precision cut spacers for the pickup mounting flange
and the strut which supports it. The strut spacers include
locking tabs which do not intrude into the windage pumping flow from
cylinder bay 1 to bay 2. The spacers are 2mm thick so you can
increase the depth by 2mm or 4mm total. A set of bolts is
included. Clay is
included to check the depth of the pickup. Full instructions
with pictures are included of course.
What you will need to have:
Tools to drain, remove and clean the pan, oil pickup and fasteners.
A tube of high quality RTV silicone gasket maker. A single
edge razor blade or X-acto knife. A ruler. We recommend
obtaining OEM factory oil pump flange gaskets -- you could need as
many as three but RTV can be used if you are careful.
Why is the
pickup higher in the pan to begin with?
We believe that Toyota does this
to help protect the average driver from him- or herself. Many
times people will hit large objects in the road, jump curbs and so
forth without a second thought to possible damage, dents and so on,
that could occur. If it keeps running it must be fine, right?
We are presuming that the people that use this kit are those who
would always carefully inspect the undercarriage and pan for damage
following such an incident, just as any serious racing crew would.
If your pan is dented you should remove and repair or replace it.
The nice thing about this kit is that it will allow you to first
establish the existing depth and then to check it later on should
road damage occur.

Reinforcement plate for the
outside bottom of the stock 1ZZ or 2ZZ sump:
This must be welded onto the pan by the customer. Helps to
minimize the danger of road damage to the immediate pickup area:
