Oil Cooler - Oil Cap

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 http://www.perfectpower.com, i am saving up for one!

Oil Cooler - Oil Cap
« Reply #17 on: June 07, 2007, 05:51:23 AM »
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...

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
