oil cooler+4age

[45aken]

hey all,
i got me a ae92 smallport in the ae86 which has a oil cooler stock, but i aint got the oil cooler.
now what im wondering is which is the best way to go about this. im thinking i can either;

a) buy good oil cooler, hook it up to the stock locations with the 'rubber' oil lines
b) buy good oil cooler, hook it up to a sandwich plate with braided hose
c) get a full filter and cooler relocation kit

now a) is very simple, but has anyone has any problems running there dodgey lines near the headers?
and with b) and c), what should i do to remover the old lines (one near the bse of the filter, and one which drains into the sump bango style)

thanks

Go a full filter relocation, with oil cooler. Dont bother using the sump return, just return straight back into the side of the block.

what do i do with the sump return? just bolt it up?

im thinking i might want to keep it for when i go turbo, i can use it for the oil drain on the turbo right?

[takai]

You can just get another sump bolt from Toyota and put that into the hole. The thread is the same.
And yes, it is good for the oil drain on the turbo, but i doubt i would use the stock fitting, the angle isnt so nice for a turbo mounted above. I would be more inclined to use an Earls or Speedflow fitting when you go Tarbo.

thanks mate, the universal permacool kits fit 4ag right?

[takai]

If you get the one with the right filter OD then yes, they will.
Cant remember how much the Permacool ones are, but i got some billet alloy adaptors from .T. (Meridian Motorsport), all up they were about $150. You can get cast alloy ones locally too, for around the $110 mark fo the two parts.

The oil cooler and lines are obviously seperately.

It's not a good idea to use the old oil cooler return fitting that is already in the sump as an oil return line for a turbo as it is too low and too small. The oil return line needs to enter the sump above the oil level in order for it to drain freely. Failure to set this up correctly will give you a very smokey car.

Remember a turbo oil drain relies on gravity and unrestricted flow to do its job

Plenty has been written on the forums about oil return lines on 4AGs and what works well. When you get to the stage of turboing have a read

Cheers.

Im pretty sure that the oil return feed on the Smallport FWD engines is well above normal oil level. Mine is up around the top of the sump below 3rd cylinder.

on a similar topic just wondering if anyone has any advice as to whether i should use an oil cooler on a silvertop 20v? Just curious as the smallport had one but the 20v has no factory oil cooler.

don't mean to hijack since it is on a similar topic.

[takai]

Yes, oil coolers should be used on all cars if they will be given some stick. End of story.

thanks for the quick reply takai :thumbsup:

yeah mine is on the high point of the sump aswell. even if it is too low, a weld on fitting is only like $10 from speedflow.

on a similar topic, does anyone know a ball park price for braided lines? i heard it's the fittings that hurt (and i know they do thanks to Mr fuel setup)

It's high but not quite high enough, all the 4AGTEs put together here have the drain as high as physically possible and are 19mm ID (vertical as possible from turbo to sump and entering the sump as steeply as possible). We have tried several methods/sizes for return lines to the sump on the 4AGTE and the stock cooler return fitting just didn't work for position (both height and location) and diameter.

There was thread about all the people who had oil drainage issues on their 4AGTE setups somewhere on this forum or maybe the old one and the height of the drain position was a big issue on most of the smokey examples.

Depends if you are doign DIY braided lines, a-la Speedflow, or crimped ones from Enzed.

DIY the fittings are expensive, and it can be a pain to make sometimes.
From Enzed It is a reasonable amount cheaper, but the measuring and then unability to change things later can hurt.

How reliable is DIY method compared to the ENZED "pro" job??? Ever had any failures?
