Modified Sump / Oil Pan

[Stain]

I was looking at using a 7A-FE sump, but found out that it isn't a easy fit to a 16v 4A-GE block.
So I'm looking into modifying a standard pan. Just wondering if anyone else has done anything similar and the pros / cons to different methods.

Seems the most common design is adding "wings" to either side to increase the capacity and baffling to help keep the oil down by the pickup during corning.
Heard bad things about trap doors getting stuck and starving the engine of oil, so kinda want to steer clear of those.

steering away abit but is the 7a sump bigger than the 4a sumps?

Im running ae101 4age sump/windage tray/oil pickup on my 7a...

I've been thinking about this for a while, what are the issues? Does something foul?

The 7A-FE two piece sump bolts up to AE101/AE111 4A-GE block but not the AE86/82/92.
Because the late gen engines have the cutout in the block/sump to clear the transfer case.

16v


20v


7A-FE against a 20v

[Hen may possibly be a nut]

Are modified/baffled sumps necessary on a 4AGE? Or is it one of those "because I can" or "because all the cool cats do it" mods?

I ask because I have many times drifted flat out all night with a 4AGZE and stock sump and pickup, come off the track and noticed that my oil was off the bottom of the dipstick. Not at all smart I know, but that motor ran for four years without any sign of problems.

I agree for the most part. I've got a mildly built 4AGE 16v and it's always burning thru oil / leaking oil...
I've driven it hard on the hills / track many times and gotten home only to find that it's got almost no oil left.

But I think the main point of 'upgrading' a sump is with high RPM engines.
As the higher the RPM the quicker the oil pump is removing oil from the sump... combine that with high g-force corning/acceleration/braking,
the little oil that is left in the sump can move away from the pickup and you run the risk of suddenly drying out bearings. Thats when things go bad.

Just a point I'd rather be safe than sorry with the next engine when it comes along.

how high RPM you talking???, if you going 9 grand plus (reliable there and hits that regulary) why wouldnt you have a a dry sump setup, and yea as said above accusump is a great idea/setup jsut do that


like if you plan on welding up something yourself, and having it as a little project, awesome go for it, but i dont think it would save an engine

Bugger. I was thinking of using the 7a sump purely for more volume/more oil which I don't think would hurt, but I see the problem...
