Mocal oil cooler & sandwitch plate ordered

Heey guys, Just found out since I have the oil temp sensor in, that the motor oil in my Hachi is getting a bit hot..

During normal drive at (120/130 km/h) it is 115 / 120 Dgrs Celsius.

I have no IC mounted on top of the 4agze.. it is a bend pipe!
But during normal use that should not make the difference..

I have seen that I have also got a Oil cooler mounted..

But (according to the previous owner) it is not wired on to the block and still left from before the swap!!
Normally 4agze's do not have oil coolers he says..

Is that true??

Cause I want to wire up the oil cooler for some cooling!!
But I have a small problem. If it is not common used for a 4agze to have a oil cooler.. Where do I link the oil drains to?

I have already got a adapter ring between my filter.. Are there any original attach points?

Other thing that I have seen is a oil filter relocation kit... (Greddy)

Just some loud thinking.. There is a "feed" and a drain "side" with valves ore something? Can I put one hose on the feed side of the relocator of the block, the other hose of the relocator (relocated piece) on the "in" and then a hose from the located piece back to the block on "drain"

Hope you guys understand me

so please a bit help on this one!!

cheers,

Roel

Dont understand your story, but yes you can fit an oil cooler. Best get rid of the stock setup though, it's not very good.
I cant understand why toyota would not put an oil cooler on a boosted engine.. if anything, those need it much more than NA 4age's.

What you need to complete a stock setup:
-adapter plate (below oil filter)
-oil cooler (duh)
-some oil lines to connect everything with
-a return plug on your oilpan.

Not difficult to do, but it's a pressure bypass system, meaning it will actually work worse as the oil heats up an pressure starts dropping. It will be an improvement compared to no cooler at all though.

Otherwise, get yourself an aftermarket thermostatic bypass type sandwich plate and a decent oil cooler (stock rx7 cooler is nice too), and plumb it all in. This would be the better apporach if you want to take the engine a bit further than it is at the moment.

From what I understood in the past was that first of all the GZE is equipped with oil squirters to cool down the engine better and second of all cool the oil by the normal radiator: somewhere (most probably in the oilpan) in the engine there are waterpipes running through transporting the heat from the oil to the radiator.

That's also a reason to upgrade (if it is still stock) your radiator when fitting a GZE. Wink

owkee.. ffies in het nederlands dan maar.. want mijn engels heeft wat haken en ogen...

Hij wordt dus warm. en ik vind, té warm..
het betreft hier nog de 1e generatie zonder oliesquirters..

de extra waterleidingen heb ik nog niet gevonden tot op heden..
weet niet wat voor radiateur ik heb, zag alleen wel dat er een leiding op de oliekoeler zit, en die is weer aangesloten, op, juist, de oliekoeler!

dus daar hebben we nu niets aan,
de setjes van een relocatation kit, ik ze kennen een aanvoer en een afvoer zijde. zal wel iets van een klep ofzo inzitten.. of hoe werkt het normaal op de plaats van je oliefilter??

dus ik dacht.. aanvoer naar de oliekoeler sturen --> van de oliekoeler naar de relocator.. --> daar door het oliefilter --> dan terug naar het blok, gewoon in serie zetten, dat alles door de oliekoeler heen gaat te aller tijden..

en anders.. Ivan,

get yourself an aftermarket thermostatic bypass type sandwich plate and a decent oil cooler (stock rx7 cooler is nice too), and plumb it all in. This would be the better apporach if you want to take the engine a bit further than it is at the moment.

waar zijn die bypassen te krijgen ??
en hoe en waar precies op aan te sluiten..

relocation kit komt vanaf waar nu je oilfilter zit.

blok -> oilrelocator -> oilfilter -> oilcooler -> blok

er zijn ook kits die tussen je blok en je oilfilter komt. Deze heeft een temp sensor en stuurt de olie alleen naar de oliecooler als de olie boven een bepaalde temp komt. Dit is praktisch omdat je olie bedrijfstemp van 80 graden anders niet gehaald wordt tijdens het cruisen.

dat snap ik niek en dan staat hij dus parallel aan het oliefilter.. maar hoe wordt dan gegarandeerd dat de stroom ook door de koeler loopt.. want het kiest de weg van de minste weerstand ?

of is dat dan juist de koeler als hij op bedrijfstemperatuur is..

en dan nu de hamvraag Very Happy

waar haal je een dergelijk kitje..

oil relocator:
bv van greddy bij turboimport:
http://www.turboimport.com/catalog/corolla.htm

Dit werkt dus als:
blok -> relocator -> oil filter -> oilcooler -> blok
Ik zet de oil filter voor de cooler zodat je geen zooi in je cooler krijgt.

passracing had de sandwich, maar die is gediscontinued. Ze zijn volgens hun site komen ze met een nieuw design.

Dit idee is dus dat als het blok op normale temp is geen oil cooler gebruikt.
Zodra de olie te warm wordt dan leid deze sandwich plate de olie om vie de cooler voordat de olie het blok weer in gaat.

Dus
temp <max> sandwichplate -> oilfilter -> sandwichplate -> blok

temp > mas texp:
blok -> sandwichplate -> oilfilter -> sandwichplate -> oilcooler -> sandwichplate -> blok

correct me if im wrong, ben geen expert Puh

owkee.. just had an chat with a guy on work... who has got lots of experience..

but a filter relocator wil do for me.. Very Happy

and attatch a oil cooler in between. ..

But there are different kinds of greddy relocation kits available..

what is the different.. cause my oil adapter ring was suitable for toyota and nissan (same thread of oil filter)

Dsc. Size: 3/4x16UNF that is the correct thread? ?

sow a nissan relocator kit is also good ??

or what is the difference ?

If you run the oil through a cooler that is in series with the filter it will take forever to get oil temps up during cold nights and do more harm then good. Thermostatic valve to open and close the oil cooler seems like the best idea. When the oil gets too hot, the oilcooler valve opens and reroutes oil through the cooling element. You are right to assume that its not being filtered when this happens (no way to prevent that really, its a characteristic of almost all systems). As soon as oil temps drop, the valve closes and the oil runs normally through the filter again.

The water cooled system from the MR2 (the tube is a heat exchanger) is pretty nifty too. Water heats up quicker then oil so it helps get things up to temp. Max temp of water is 100degrees so it does help a bit with the cooling when things get hot. Probably not that much though. Would be a nice addition to any car if the pipe can be plumbed in easily into the AE86.
Don't see it fitting in easily though.

The oilchange is on the cold waterpipe, so it will always be less then 100 degrees, otherwise you would really have an coolingproblem. :p

My Reno 5GTTurbo had the same system in the radiator, worked perfect untill i started to make some real power.
Then i bought an Mocal cooler with an thermostat in the sandwitchplate, it was always filtering

from my untherstanding.. the mocal sandwitch plate, allows the oil to always run trough the oil filter, couse the adapters for the cooler hoses is on the "return side of the block.??

so in that case oil is always filtered before entering the oil cooler?
(see First and seccond Picture)

Iff the center of the sandwitch plate is the "In" for the oil filter and the outside the surrounding border..

also found this kit on Ebay..

http://cgi.ebay.nl/ws/eBayISAPI.dll?ViewItem&am...otn%3D4%26ps%3D42

I dont think that it has a termostat..

and also this one of mocal with the right thread ... but do not know if the total dimentions are the same like the with of the oil filter..

http://cgi.ebay.nl/OIL-COOLER-PLATE-E21-2002-E3...otoQQcmdZViewItem

in combination with these..

the auction does say that you can get an thermostat for another 20 19.99 pounds.

1st and 2nd link seems to go to the same auction btw...

Posted: Fri May 09, 2008 3:16 pm Post subject:

my mistake.. the second link is to just the sandwitch plate with termostat 3/4 UNF
and 5/8" ID hose hose ( 16mm innerhose)

so a complete kit with 16 row cooler and termostat will kost me inc shipping £ 135,- ex paypall fee..

and £ 62,- for just the sandwitchplate and hose adapters..

but I dont know of the quallity of the cooler.. and have still the ori cooler..

what do you think.. Or what cooler would be nice If I buy here just the sandwitchplate... what cooler is needed/ prefferd?

Thermostatic valve does seem like a great idea, but the more moving partrs the less reliable .

you can always do like i do ...
manual thermostat Puh

a cardboard is always in front of the oil cooler.
I only remove it on track days

but as in every manual thing you have to keep an eye on the oil temp to know if you need to remove the cardboard or not .....

and what are acceptable oil temps for our 4ages???
