Engine Conversion. 2JZ-GE into MS53 Crown

[TheToyman75]

It was another sleepless night with plenty of headaches but the wagon is alive and will be at Dyno day 12 !

This will be a great conversion Rod.

Before you go too far with the conversion, in particular the steering box, you might want to do a quick test fit of the motor. When I dropped the 2JZGE into the MarkII, the standard manifold actually fouled the steering box. I was always going to get a set of extractors so I was pretty unfussed, but this might be something to check before you go too far if you plan on using the standard exhaust manifolds. The 1JZGE exhaust manifold (single piece jobbie like a 5/6/7MGE one) is slightly lower profile and might give you the clearance you need (if you need any).

GT,

I didn't bother checking the exhaust clearance when we droppd the engine in as the original plan was always to get a set of custom headers made. With the rush to dyno day I took the plunge and hunted up a 1JZ-GE exhaust manifold. It arrived on friday and with very minimal mods if works a treat, you dead set couldn't have asked for anything better.

The bottom middle two exhaust stud holes were smaller than the others and had to be opened up and to fit it past the steering box easier I removed the rearmost heat shield stud. I could put it back in now its all bolted up, but hey tin snips on the heatshield was quicker

Only has a temperary set of side pipes to get it to Dyno day, no cat and no o2 sensors . I should have the new pipes sorted soon tho. Pics to come soon

Excellent news! Pics of the 1JZGE manifold in place would be sweet.

And maybe +1 rep? LOL

Prediction 125rwkW......

[Alchemist]

Yup, great work to get it going Rod! I reckon maybe more than 125 as it's got no cat...keen to see another 2J in action, actually I reckon this dyno day will see the most 2J's ever...

Crown engine swap - 6 weeks,

Celica engine swap - 6 years.

123.5 I think it managed, mighty fine effort, this is a very very tidy install too might I add!

Anthony,

Countless hours, 6 Weeks, 5 Cases of coke, 4 all nighters, and 3 litres of on tap fun. Its no tyre frying demon but it wasn't meant to be. Its a cruiser and I'm stoked with it !

It we hadn't tackled a brake upgrade, power steering conversion, dash refurbishemnt and converted it to an Auto all at the same time I recon we could have had it finished for Xmas. I have to say a really HUGE thanks to the guys and gals who leant a hand. there were many faces who swung buy to help but in particular it was the constant support of Josh, Mos, Dav and Stitt who made it come together so quickly. Far to many sleepless nights and early mornings were spent to make the Dyno Day target.

I still have have to tidy up a few loose ends and get the enginnering side of things finalised but its basically done. I was actually expecting 115 - 118 for the dyno result, its an Auto afterall. I'm very happy with the 123.6kw but of couse the cat will make a little bit of a dent in that when it goes in. Either way its worlds better than the 49.2 kw the old 4M used to make

[Gold28]

Was just having a dig mate.

123rwkw should get Kirsty and the kids to the shops quick enough. Whats it like to drive now?

Fuel System

The fuel system was one of the biggest non engine changes so I figure it deserves some detail.

The surge tank pumps and filters are mounted under the rear on the passenger side. The custom made surge tank is 7" high and 4" in diametre. The fittings a 3 x 5/16" and 1 x 1/2" to suit the fuel lines and main pump feed size.

The lift pump is a Carter Gold and is prefiltered by a Ryco carby filter (Z14) it has 5/16 barbs. The main pump is a Bosch 070, (Same pump as a VL turbo), before the pump is a 1/2" inline prefilter. This way both pumps are protected if I collect any dirty fuel. Up in the engine bay is a Z200 EFI filter to keep the smaller shit out of the injectors.



The return line is plumbed into the factory filler neck. All I need to do now is fit the Charcoal canister and the fuel system is done

Auto Cooler - The MS65 engine oil cooler is mounted up front as an Auto transmission cooler and should do the job nicely.

Speaking of cooling, The Top radiator hose is a tight twist so a slightly larger flex hose was purchased and the spring from inside it was slide inside the radiator hose to stop it from kinking or restricting flow.
The thermo fans are triggered by an in radiator switch set to turnthe fans on at 85 deg, buyfittingthe switch at the bottom of the Radiator this seams to work well. The fans themselves are mounted on alloy flat bar and angle. There is a 12" and a 10" fan.

The exhaust manifold as previously mentioned is the 1JZ-GE manifold and fits like a dream



In fact the whole engine has been a really nice fit

[CLG]

Do you have a make and part number for the 1/2" filter please Rod?

How is it to drive........ Lets just say Kirsty won't b driving it after all The power steering, Auto and the extra ponies has madeit a really sweet cruiser. The brakes get the new master cylinder and bias adjustment next Wed so that should finish off the package really well.

Its no tyre frying demon in fact it doesn't do skids, but its gets off the line nicely and kickdown from cruise is really responsive. I honestly couldn't recommend the 2JZ-GE highly enough if your looking for an N/A engine. Sure its no 1UZ, but its close and it fits !

Best thing about the conversion tho, shut the bonnet and you wouldn't know its in there open the bonnet and it looks factory, turn the key and man it growls. ( I will deffinatly need a second exhaust for the engineer lol)



(well if you don't notice the side pipe anyway )

[Gold28]

Thumbs up on the side pipe and teh new wheels look mad. They are begging for some whitewalls though.

[CrUZida]

Fans turn on at 85degC? Are you sure?
Isn't the thermostat 82degC?

[gianttomato]

Now that is a fuggen tidy conversion done in good time. 1JZGE manifold is still snug, but I'm glad it got you out of the poo. Thanks for the picture.

I have to ask what the airbox is out of?

Mad props on the 124 rwkW!

A modern motor with actual "get-up-and-go" transforms these cars from a clunker to something that's a hoot to drive.

[MS-75]

Excellent.

Now paint that guard and hood Mister.

[Alchemist]

Sure its no 1UZ, but its close and it fits !

It doesn't have the Torque, but I'm sure your 2JZ made more than a 1UZ from last dyno day...and in a striaght line the numbers say in a similar car that the 2JZ is a little quicker, hows it bad(or am I biased...).
