Hey guys,

I was looking to run an external rx7 oil cooler for my gsr motor, that I will be putting in my da.

My only question is should I run a sandwich plate for the feed and return lines, or a vented valve cover?

I feel like doing the sandwich option will cause a drastic loss in oil psi, because of the distance it has to travel. I also feel I will lose oil psi if I go with the vented valve cover route, due to the oil being returned to the head instead of back to the block?

If anyone has any setups or info they care to share, I'd appreciate it. As well as info on which route I should take, meaning the sandwich or valve cover option.

Thanks guys.

 

Skip it

 

^^in for someone who has something valuable to contribute. If you don't have any insight related to the topic, don't post. Thanks.

 

The gsr already haves a half *** oil cooler , and besides unless your your taking the car around a scca track multiple times you don't need it , the only thing your gonna get out of it is you will be able to tell your home bois you have a jdm rx7 oil cooler in your honda that you drive to work and back ....

 

This will be my autox car, and what does it matter to you? If you don't have anything useful to contribute **** off.

 

I did some reading on a oil cooler.

From what i understand both B in your case and H in my case have oem oil cooler which work with the water circulating in them cooling oil.

but when i swapped to a F block that is not a oem option.

The setup i have gone for is a front mounted oil cooler with 13 rows 235 mesh from mocal. along with that oil sandwich with thermostat of 80 degree celcius to make sure it does not over cool.

Also upgraded the oil pump due to the now longer circuit of oil travel went for a KMS modified oil cooler.

I am yet to install everything or i would give you pics. I hope to ventilate the valve cover at some stage.

My 2 cents

Regards

 

okay thanks Honda 12v, will your vented vc just run to a breather? I am still lost as to which option I want to take for the cooler. I may just have to try both options and figure out what works. If anyone else as info feel free to post.

 

Have you every thought about a larger capacity aluminum oil pan? Maybe one that has fins?

 

^yes I have, but decided not to go that route.

 

With a sandwich plate there is not going to be a huge drop in oil psi , if it is for serious auto x the bigger baffled pan is a decent idea gotta remember hard turns are gonna shift the oil in the pan a lot more could cause you to hit dry spots , the Oem gsr cool is like how he said water circulates threw where the oil filter is. To keep the most pressure a small oil cooler in front of the radiator would be ideal.

Remember when you install to start the car for a few seconds shut off and top oil off. the easier solution would be sandwich plate to a an line to oil cooler to return an line to pretty much where the turbo drain line would go on a oil pan so to speak.

Make sure you have good oil pressure now befor doing this , are you running forged pistons ? If so you can delete the oil squirters in the gsr block for a couple extra psi

 

Thanks for posting something worth reading. The setup is in my dc, before I got deployed I never got a light on the dash, vtec crossed over fine, and nothing is scarred in the motor.

No Im running a rebuilt stock bottom end. When it gets put in the da I will run a psi gauge and a temp gauge for the oil. I will do the sandwich feed and pan return like you said. Thanks.

 

When I fist read your post I judged it like most of the post I read on here and sorry for that , I checked the threads you started befor and figured you just wanted the oil cooler kit for appearance so it was ,my fault.

Most auto x tracks are pretty short and you get some time befor your next series of laps , you might be able to skip the oil cooler and just upgrade the cooling like duel core rad , and better thermostat , fal fan that will always stay on.

 

On the VC i did some reading, am going the simple route

Will make two holes on the back of the VC run them to a simple catch can.

I dont know i dont want oil to run back to the sump, i prefer to throw the oil instead of recirculating the whole thing.

I have a F block with forged pistons, removed the balancer shafts to free up some pressure.

From what i understand the allu sump with a larger capacity if your best bet cause like mentioned it with hard side to side forces your pick up will still have oil. But you definitely want a thermostat so u dont over cool it.

Also if it is serious racing, why not look into a accusump setup??? I have read so many good things about that.

Regards

 

Its okay skunkedgsr, I understood where you were getting at, that's why I called you out haha. Ive been on h-t for a while just had to get my account straightened out. yes this will be my weekend racecar. If I do the option you suggested should I place my oil temp gauge running from the pan?

Honda 12v, Im not looking to get a dry sump or anything of that nature bc I am not willing to spend that kind of money.

 

well,

From what i read accusump is not a dry sump solution. Its a oil back up reservoir which holds a certain amount of oil. Which is then connected to a pressure sensor. When the pressure drops it introduces the oil to protect the engine from oil straving. When the pressure goes back it simply takes back the oil it once added.

It can be run automatic or manually. Makes sense to me honestly.

Last time i ran the numbers it was 250-300$ for the whole setup

But i maybe be wrong

Regards

 

That's really sweet, Ill check them out thanks bro.

 

personal experience with my GSR swapped hatch:

i live in the hot *** south, and track my car several times a year, during summer, at places like road atlanta, barber, etc.

running the stock oil cooler that all GSR's have, my oil temps never got above 220, measured with a temp gauge, even in 90+ degree temps and 20-30 minute sessions.

i'm under the impression that you really don't need an aftermarket cooler, even during autocross, as your sessions are much shorter. but it's your car...

 

Thanks for the advice Cynical 1 I live in NC so our summers are very hot as well; really muggy!
