Can the sump be shortened in height at all and will the engine cope ok.

Why would you what you reduce your oil capacity? There is a dry sump kit for the 5 pot, but, it ain't cheap! :jaw:
Im converting to rwd and i think im gonna run into subframe issues i hope i dont have to chop the sump up.
I have seen pictures of people shortening the sumps, on other engines. As long as the oil pick stays in oil all the time, I can't see why it shouldn't hurt
Anyone ever built a dry sump?
I would think that you'll have to weld some wings on, so that you can keep the capacity.

If there was less oil capacity in the sump would it damage the engine
[quote=850Rick;465859]If there was less oil capacity in the sump would it damage the engine[/quote] It's not something I'd do, it's the life blood of the engine.
[quote=850Rick;465859]If there was less oil capacity in the sump would it damage the engine[/quote] Just a bit! Its not just the engine itself that needs oil, the turbo has to be fed to.
Don't drop the capacity. As above fit some sort of extra capacity. The sump has baffles that will be a nightmare to alter when adding wings so dry sump and accumulator may be the best method.

Why not put a big oil cooler on as will increase capacity and you could always look at making a dry sump system.

[quote=endo-t5;465912]Why not put a big oil cooler on as will increase capacity and you could always look at making a dry sump system.[/quote] That sounds like a very good idea,would i keep it as close to the sump as possible and sort of at the same level as the sump?
If you wish to 'shorten' it as you put it, then DONT even touch the lower pan. Insteadabout an inch below the mounting face cut it all the way round, you then do it again to the remainder of the sump removing the depth neede and then weld the mateing face bit back on. Thus every thing is the same except overall height. HOWEVER.................................THAT wont be your biggest problem!! What will be wil be the fact that you will need a sump with a REAR lower drain pan and accompanying filter/pipework. Pies can be made to fit relatively easy and it might be easier to pinch the lot of a rear engined car and do the bit I said about cutting the mounting face but just weld it onto the RWD sump.
Ive not got it sat in yet ive only just removed the t5 engine today.I do think i can keep some of the sump so it will be like an L shape and maybe i put the baffle lower down in to it
This is something I need to look into. I will be using a 960 sump, and Im fairly sure I'll need to alter the pan to avoid the subframe/ARB. I was thinking of possibly shortening the pan (front to back) but making it wider to keep the capacity up and maybe also to fit a pressure accumulator (if thats the right thing) just to be on the safe side.

[quote=850Rick;466241]Whats the point in using the 960 sump?you still have to chop the sump about dont you.[/quote] The 960 sump already has the 'wings' on it, got to be easyer just to shorten a 960 sump I would have thought.

Whilst I believe the pan does just miss the subframe, the ARB and steering rack are in the way. I dont want to get into moving the rack that might cause steering issues, so altering the pan seems the option to go for. Its only one edge of the pan that needs altering to clear the rack and ARB I think, but whatever I take out of that edge, I'll try to extend on another. It is possible the 850 sump may fit with less work, but that I cant tell untill the engine is suspened in place.
