Oil Cooler - Oil Cap

[vatos_p]

i am looking for a cheapest way to put an oil cooler to my m42 , and not VICTORY ( 255 $ + shipping )...

does anybody know any ???

[rob_e30]

Having a Victory cap in my posession now I can tell you that it's a lot more than just a cap. You might be able to tap into the oil housing to get it done but this is not a project you want to do on the cheap.

Having purchased the cap and pulled together my own oil cooler, steel braided lines, and fittings you don't even save much (provided you purchase the same quality parts) versus buying the whole thing from VPD.

Don't Forget That I Am From Greece , And The Shipping For That Thing Is More Than The Cost Of It For Me...

[vatos_p]

like all greek people , the patend is in our blood , i managed to find a person that fibricated one oil filter cap with oil cooler output for me , for only 70 eyro .

Sweet! Does it have a thermostat?

[e9nine]

+ 1 on the existence of a thermostat? Nice to see you guys have some "resources" available for such projects :)

1. the oil filter cap is larger in hight and in width

2. the central hole for the holder screw is bigger , also the hight of the screw got longer and the diameter of the screw head is bigger with o-ring under it...
!!! attention the screw (diameter) itself did not, exept the head,got bigger to leave place for the oil to goi all the way up...

the pick-up hole is a T hole... ( see pictures )
bottom end is for oil pick-up (oil line to cooler ) , left end is for oil press sensor ( outside ), and right end is oil passage for both...(it goes all the way to the center screw )

the return hole is also T hole ( see picture )
bottom end is for oil return (oil line to cooler ) , left hole is for oil return to the oil filter ( inside ), and right hole is on top of the cap (outside) for oil temp sensor...

if you have any questions please ask..

Thank you. What is the distance center to center of the main pick up and return? I see that the return line travels to the center of the cap, where does the pick up pick oil up?Thanks
here are the drawings, not sure where to put the pick up hole in the cap.

I Think You Can Understand Now...

I Did Not Think This My Self...i Copyied The Idea By Factory One And Victory... And Combined Them Together With A Very Talented Lathe Expert And I Got My Result...

[m44power]

i want one too! :D i love greek patent :P but we need some ideas for a thermostat

[nobrakese36]

I see oil is picked up from the center of the oil filter housing!!

[nobrakese36]

Is you oil cooler up and running, also how is your turbo project?

[vatos_p]

about thermostat look at the pictures...

http://www.m42club.com/forums/showthread.php?t=2077

ford cosworth uses these , (my bmw also uses this now ) so you can use this also..
yes my oil cooler is already working , and it is working fine...
from the day i put it on , i haven't seen oil temp more than 90 celcius with full throtle and 220 Km/H ( have in mind that oil is also heats up in the turbine ) so i think it does a very good job...

about my turbo project , is has now 2 mothns working fine ( without intecooler ) because i have just finished fabricating the new hood i am going to use for my top mount intercooler project..

hope i finish soon and post pics...

[nobrakese36]

Any more pics of turbo set up!!

[vatos_p]

here 2 pics...

if you want more , you must wait until i finish..

that is where the intecooler will stand , when i finish my hood , i will also keep apart the engine and the intercooler with a carbon wall so heat wont come on the intercooler ...

you will see..

[nobrakese36]

Awesome, on a internal wastegate turbo, how do you adjust boost? Is it in the lever arm?
Also what are you doing for tuning, look into the smt 6 from www.perfectpower.com, i am saving up for one!

[vatos_p]

i am already using SMT-7 witch is the smt-6 with electronic boost control intergrated...( so i have answered both your questions )

I just bought a '90 318Is. I had one 15 years ago, when they were rather new ones. Since then i have involved Porsche 944 Turbos. Have own one almost ten years. I bought this IS mainly because it has MTech II body kit, which i used to have 15 years ago. The colour is also the same Brilliant Rot like my old car used to have. so i am takeing a time travel back to early '90's ;)
I first plannd just to take body kit from this car and but it to a 325 i also bought.... But this 318IS is in much better condition, so i sold 325. Since i have a lot of Porsche 944 Turbo parts around i plan to get M42 turboed. I am going to use original Motronic with tailored chip. Also 944 Turbos engines wiringharness will be install to M42 with Motronic DME & KLR boxes. KLR box handles the boost and knock. I am not going to use original air flow meter, i use AFM Link box with MAP sensor. I am going to use M42 Motronic, because 944 Turbo has only two hall sensors loacted on the flywheels and does not have a similar set up like M42 has. There will also be low CR pistons and more cubic cm's; i will convert it to 2.1 L. The turbo will be KKK 27/8, with modified Holset inserts. Inter cooler will be a modifed Porsche 944 Turbo unit. With similar modifications i tooked 368 hp from 2,5 liter 944 turbo engine with 1,2 bar boost. I am currently in the middle of building a 3 liter engine with bigger turbo to my 944 Turbo, so i have a lot of parts available for M42 turbo project. The plan is to keep this as simple as possible, so most likely i will only take about 250 hp from M42 engine. I am going to use VEMS standalone system with my 944 turbo, so if the results are good enough, i will also adopt it to my 318IS.


That modifed oil filler cap looks nice. Do you thing it's possible to produce more of them? Since i am also living in europe, EU area, wreight & customs won't be any issue.

Great thread, Thank you for sharing, i just have a question of how it works:o:
Am i correct in understanding the oil feed comes up through the oil filter centre and returns on the outside of the filter?:confused:
If so, when the external thermostat opens the cooler up, does the filter get by-passed? It obviously works well:cool:, i'd just like to know the principle.
Thanks

As I understand oil cooler is connected paralel to the filter?


1. the oil filter cap is larger in hight and in width

2. the central hole for the holder screw is bigger , also the hight of the screw got longer and the diameter of the screw head is bigger with o-ring under it...
!!! attention the screw (diameter) itself did not, exept the head,got bigger to leave place for the oil to goi all the way up...

the pick-up hole is a T hole... ( see pictures )
bottom end is for oil pick-up (oil line to cooler ) , left end is for oil press sensor ( outside ), and right end is oil passage for both...(it goes all the way to the center screw )

the return hole is also T hole ( see picture )
bottom end is for oil return (oil line to cooler ) , left hole is for oil return to the oil filter ( inside ), and right hole is on top of the cap (outside) for oil temp sensor...

if you have any questions please ask..

yes , the oil cooler retunrs the oil inside the filter again but unfiltered , but the amount of the oil not filtered is not so great , and the oil is filtered anyway all the time , so i don't think there is a problem... but if you want it otherwise , you can make the same cap adapt all the oil for the filter sent it to the cooler , and then filter it with a remote filter , and then retunt it to the factory oil filter housing... but i don't see why...

[romkasponka]

but i don't see why...

because:
1) you suply unfiltered oil to the engine and imho that is not good,
2) circulation through oil cooler is not known, maybe it is 10% of all oil? :)


It is better to make plate with in and out holes for whole filter housing replacement with external filter and radiator, or just replace your filter cartridge with steel (or aliuminium) pipe with two O rings in the ends.

I think the flow is compromised, But it sounds like the flow plus an increase in oil capacity is enough to improve cooling:cool:. It may take me a while :( but i'll share my results. Thanks again
