1JZGTE into 7MGE MS57 crown

[JesseCrown]

hey all
my crowns head gaskets gone pop
and rather than fixing it im looking at going to 1J, cause i was planning on doing this soon anyway.
from searching it looks like a i need a midrear sump engine ?
and i've heard the twin turbo will hit the steering box, would the single turbo vvti 1J fit?
has anyone done this yet?
and would the W50 bolt up and handle the 1J? most the driving i do is pretty light.
and looks like ill need to make some custom engine mounts.
anything else i i should be considering or problems ill run into?

thanks, jesse

You need a true midsump (from a JZS131 or 133) - you can modify a JZA80 sump to work.

The rear turbo will hit the steering box. You could make a new rear manifold to high mount the rear turbo so it clears or you just go straight to a single.

The VVTi 1JZ looks like it will clear. I have seen photos of one in an MS65 (similar problem).

No but Dellow do make a bellhousing to suit. Not sure it's such a great idea - you'll blow the shit out of 5th gear every time.

Room for an intercooler (although Stitt snuck one in there), fuel system, wiring, usual other conversion crap.

One thing that will cause you grief is the dipstick - believe it or not it wants to be right where the engine mount is. There are a few different solutions but they all involve relocation.

i was hoppeing to keep it all stock and run off the factory ecu for a while.
so single turbo would be the way to go so i dont have to modify anything.
whats the best option for gearbox? im not sure what box stitts running behind his but i know theres not much room in mine for anything much bigger than a w50
are the single turbo midsumped 1J's common?

[JesseCrown]

and i dont quite unerstand this front/centre/mid sump business, im assuming that their sumps are not interchangable so i specifally need a mid sumped 1j?

[gianttomato]

All sumps interchange.
Ideally, you need this sump:

Just get a rear manifold made up so that the rear turbo misses. You'll also need to make up new dumps but that's a good thing. This way you can buy a cheap old twin turbo 1JZ and run the std turbos and ECU.
Just run a W58 - pretty sure that's what Stitt is running. Use a JZ-W58 bellhousing and flywheel.

ok so i gather its not easy to track down just a mid rear sump on its own then?
im just trying to figure out the cheapest easiest option to have a running 1j, im happy with keeping it dead stock for a while.
i would have thought getting a rear manifold made up would be pretty tricky.

so far looks like W58 is the go.
plus a stock single turbo vvti 1J

if i cant find one- a twin turbo 1J with either a single turbo conversion or mods to manifold?

i suppose a single turbo conversion would mean i have to run a aftermarket ecu?

[whatthe?]

I believe I have the pictured sump in my collection of crap. I'll check and let you know. Dont need it as my vvti 1J is in an MA61

Edit - Nope, it's another front sump Sorry!

W58 apparently will fit where a W50 used to live. Same length but different shifter locations / mounting points from what ive heard on here.

How do the turbos foul on the steering box?

If it's anything similar to the ol' 1G in a Celica then maybe the 10mm etc spacer between the mounts and rubber could suffice.

Nice to see the pimp mobile gettn so go juice

How do the turbos foul on the steering box?

It's not like they're just touching - the turbo wants to be in the same place as the steering box. There's no room to fit a std 2JZGE exhaust manifold there (see Rod's wagon thread or my 2JZGE into MX23 thread) so to fit the turbo in the same spot given that they stick out a good 30 - 50 mm more just isn't going to happen. Steve Shipway did this conversion 18 million years ago - ended up using a merger pipe between the two std exhaust manifolds and running a CT26.

If it's anything similar to the ol' 1G in a Celica then maybe the 10mm etc spacer between the mounts and rubber could suffice.

Not a hope in hell.

Only options are to relocate rear turbo, big single or VVTi 1JZGTE. As far as singles go, I have pics somewhere of a 1JZ with a HKS manifold and GT30 in an MX13 that Shifty was going to do. The fit was nice with plenty of room.

I really want to see this happen. I think it's a sweet conversion.

shoot me down in flames why dont ya GT

well thats out then i guess .. was worth a shot.



on another 1G related note IN 05 NT is running a larger single turbo on his 1GGTE on
standard ecu atm. apparently it runs rich more than normal but maybe a slightly cheaper option (if the 1j ecu can) is to bolt up a single turbo and use a fuel adjuster like safc etc to bring it back within reasonable AFR ratios?

Then later on go the full aftermarket ecu etc???

[gianttomato]

LOL...wasn't meant to sound that way. Sorry dude.

1JZ VVTi FTW. Nothing beats a factory looking conversion. Also the donks are newer, make around 200rwkW out of the box and there are aftermarket options for them if there's the desire later on.

[TA-022]

heheh its all man love in here GT no dramas.

But from old convos I thought vvti 1j's werent easy to source?

Edit: either way get some more pics up Jesse

[JesseCrown]

i got bored this weekend and did the 7m head gasket.
but this conversion is definately happening, just going to get the diff, brakes and gearbox sorted first

[JesseCrown]

so are the vvti's a lot harder to find and more expensive??
