Sumps

The easiest way to identify an engine is by the sump location. All engines feature an alloy sump that adds rigidity to the block with a bolt on pressed steel cap for the sump pan itself. LS400/Lexus/Celsior all have a front sump. I suspect the Aristo does too. These work best with Hiluxes/Surfs/4-Runners and Altezzas. Crowns have a centre sump, whilst Soarers and ambulances have a rear sump (well, further rear than the centre one). Rear sumps work best with GA/MA/JZA-70 Supras. I had previously been led to believe that centre sumps were Soarers and Crowns were rear, but this information was incorrect.

Front sump engines need some minor modifications to the steel pan to clear the suspension/steering in Hiluxes etc; VVT-I engines have a clearance already built in.

Generally front or rear sumps are the most sought after. Rear sumps are the least common. If you have an engine with one of these and need the other, odds are you can swap it for the opposite with someone else (once you find them). Centre sumps tend to be the least popular (as they invariably need modification to fit anything) yet most common, so being able to swap one for a front or rear is less likely. I actually managed to swap a front for a rear plus made $200 on the deal (I was quite happy just to do the swap, but when they offered money as well…)

Some people have fabricated new sumps complete, but I would be wary of losing the rigidity the alloy casting provides the block. Be aware that front and rear sumps both have fully external dipsticks; centre sump engines have a hole for the dipstick drilled into the top of the block, which becomes an issue if you swap a front or rear to centre – you will need to drill into the top of the block…

If you do decide to swap sumps make sure you get everything, as you need to replace everything including the alloy casting and steel pan below (which differ between the 3 sump locations). Not only are the internal pick up tubes and windage trays different but the bolts are a different length also. Oil filters are either front or rear mounted, but the pump outlet remains at the front, so the centre sump engines have external hard lines going to effectively a remotely mounted filter. Don’t forget the dipstick either.

Be warned that IFS Hilux/Surf conversions will generally require an aftermarket remote mounted oil filter as there is no room for any of the factory set ups, although you could conceivably custom modify the factory set up if you are patient enough. We have found it costs around $500-600 to remotely mount the filter using braided line and Aeroquip type fittings. Throw in even more money if you want to add an oil cooler. The good news is the VVT-I engines run a different set up that clears the chassis.

The oil filter mount on a rear sump engine fouls the sway bar on a Supra; the Crown remote type rear oil filter assembly fits but makes oil filter access a little difficult (depending on fuel line location). I ended up getting a custom sway bar made that cleared the factory oil filter mount.

Many conversions will still require the steel sump bowl to be modified to a minor extent to clear things that want to occupy the same space. Usual story – trial fit it and chop off anything in the way!

API SG, ECII 5W-30 or 10W-30 are the preferred oil grades according to my copy of the US service manual. I use 5W-30 Castrol Formula R full synthetic. Sumps hold around 4.5 litres (there is a slight variation between them)

Oh! Is that different installs for the Soarer/LS400, what's the other one? :)

The other one is a more older car IIRC, its toyota not a lexus. It is a square shapped car. I just cant think of its name Atm


Edit: In penskis post it just said the Celsior so i would say its that :p
 
The Toyota Celsior is just the "Toyota" badged LS400, so I'd be suprised if it was different (was the one sold in Japan and Austrailia AFAIK)

LS400/Lexus/Celsior all have a front sump

In fact, there's the answer in Penski's quoted source :D

Bah!! Theres too many cars too think of with similar names :p

Then You also get then 3UZ-FE going into cars to make it harder to remember whats what :p

(I dont think the 3UZ is as strong as the 1UZ. It is lighter though but havnt heard much about the tuning capability)

You'd have real problems with a 1UZFE in a GT6, it's a massive motor - maybe the depth and length of it can be overcome but it's one wide sucker!
It'd have to be moved so far back into the bulkhead, methinks.

Measured up one for the Dolly and it wouldn't fit without substantial hacking of just about anything! :D That includes the bulkhead, floorpan, turrets, nose :p

I don't think it'd fit in a Stag without reworking the suspension turrets, so you'd have to check that though, I haven't looked at the dimensions. I know a Stag engine will fit in a Dolomite bay sans cooling pack....

You'd need a 5 series conversion for the rear end of the Stag to handle the output though - the halfshafts and crownwheel wouldn't take it :)

It may not have to be moved too far back for handling as at 175kilos it's still lighter than the Triumph 6 pot. However, it sounds like a real job to get it to fit at all. Rover is probably better, or just strap a blower and EFI to the 6 pot already in there.

As for the Stag, it doesn't sound like it would fit easily, and there's better metal to put in there than this by the sounds of it.

I'm thinking about the Monarch 3 series kit for the Stag anyway. I'm just not sure if I want to change it, go for the scimitar, or just forget the lot and buy a Jag S-Type R or M5. I roughly guesstimated the cost of the scim the other day and I was looking at around £25k for the lot (chassis work, respray, retrim, ICE, etc. etc.). That's going on a brand new engine and box though. But if I made the changes I wanted to, putting in a cheap, tired motor would be a waste of time.

yes, I know the Jag or BMW wouldn't have that classic charm, but it has air bags and crumple zones and wouldn't automatically kill me if I was involved in a head on at more than about 40mph, like the GT probably would (at least I wouldn't be walking again, even if I didn't die, my knees press against the bottom of the dash in both cars).

Ho Hum, decisions, decisions!
