Engine choices... Enter the 2JZ question

[R0ACH]

Ok, so Ive been blessed with the bad luck of having my motor pop. E39 - 528i - Head gasket, water pump, etc etc ...

Ive tracked down another motor. Its also a 2.8 single vanos like the one i got. So its a plug and play setup, i hope!!!!
Now heres where things get sticky...
For the price im paying for the 2.8, if i throw another 4.5k at it, i can get the 2JZ engine :yikes: . I know the purists out there will want to rip my heart out through my arseside and stick a sharp object in my head and give me a good :floggin: (please - just dont ban me, i couldnt handle that)
The thing that got me thinking about it is that for about 30k, ( I can do all the dirty work myself) I will have a car that will put out alotta more ponies and be reliable and have reasonable cheap engine parts too... Sure, it wont be an MFiver but it sure will be fun to drive.
The cars themselves do not have a good resale value so if i do it, I know im gonna be marrying the thing but I am kinda attached to it (sentimental bla bla).
Hey guys, Im stuck between a rock and hard place. Spend a little cash and be ok with the car and prob sell it for peanuts in a year, or spend a bit more and keep it till the wheels off but at least get a smile factor thumbs up when i put my foot in the corner.
Ok - let the games begin...

- Has anyone done this or it not recommended or whats the pitfalls etc etc...

When you say all the dirty work... Are you able to make custom mounts? Custom propshaft (I'm assuming this is needed)? And all the other additional custom fabrication that's going to be required? Does the engine for 4.5k more come with a gearbox? Are you going to need a new clutch and flywheel? Have you factored in the price of a turbo, or does the engine come with one? Have you factored in aftermarket engine management? Then you're probably going to want an LSD, enter m5 diff swap etc.

If you're not relying on the car as a daily and have cash to spend to complete the build and not halfass it then 2jz. If you rely on the car or don't have cash to do it properly, then keep it simple.

Thanx for the feedback -
Dirty work - Yip, Im ok with a grinder and a cutting torch and welder... Can even bake a cake... an evil cake :chef:
G-Box - will use the std one with an adaptor plate. I got the manual box so thats a small bonus- so the propshaft will be ok too.
Turbo - the 2J comes std with 2 of those little thingys...:coolShake:
I priced the full install at 30k with the things needed incl an aftermarket management (prob go gotech or diktator).
LSD - nah, not for now, let the tyres smoke a bit.
Its not my daily driver, its actually just a huge paperweight at the moment...:thumbdo:
and Yes, do it right or dont do it at all...

Do it if for nothing else other than to piss off the purists.......

I think a 2JZ E39 will be a sleeper of note.. :tiptoe:

I would get the proper gearbox for the engine. Its such a headache adapting a box onto an engine. Then you also need a flywheel spacer which needs to be machines to spec. Then since your pushing the gearbox I'm assuming 20mm further back is the prop shaft going to be the same length? I doubt there's space to move the engine forward more. Then you're also need extended high tensile bolts. I paid about R100 a bolt for mine. Just remember it all adds up and by the time you've had the spacer machined up etc you may as well have just gone with the proper gearbox.

Also pushing the box back further your gearbox carrier is no longer going to fit. So more custom work.

As far as the turbo goes, you're going to want more power eventually and since its not the daily why not go big off the bat? And just do single turbo?

Also I wouldn't skimp on the management system. Are the local ones up to the task of running 2 turbos? Let alone 1?

Anyway just something to think about. I really hope to see this build come to life.

And what are you going to do about brakes and suspension?

I did a 1jz on my e46 ,cost always ending up more than expected ,mad power,faster than my m5 on the 400m. I will say this ,there will always be something to do on the car,so perfect to keep one busy and entertained

There you go fixed

Just thought that a response in the language you prefer was appropriate

 

[terrencem5v10]

:ty:a bit broke is right, used to eat clutches ,it's so easy to make more power and we all greedy for that,so we keep pushing till something breaks

 

[nirvash]

not a bad idea in my opinion, e39's are beautiful chassis so putting in something beefier then the 2.8 n/a is more then welcome,

with projects like these as mentioned, always budget about double what you think you should budget, the grocery list always gets bigger so be prepared,

also the std twin turbo setup is sequential and apparently extremely difficult to get running without the std ecu, thats why i think a single turbo setup should be in the budget, thats the route most guys go,

also im not sure how the 528i box will hold up and if you plan more power in the future i would suggest going for one of the stronger toyota boxes,

even a 1jz would be nice and somewhat more cost effective, and dont have to go aftermarket single turbo with that, it runs parallel chargers not sequential so you can use whats on the motor right of the bat. nothing wrong with these engines at all, can make great power with them as well,

also just a suggestion, but maybe a 1UZ V8?

sound like a good idea, i say go for it:thumbs:

They say that life is great with a V8 --- but i would rather be blown... :=):
1JZ. Well well - will look into that. I know that the preferred is the 2J, but with what i have in mind maybe a 1J will suffice my needs.
Another reason i wanna go I6 is that i want to get the rev counter etc to still work, that means hooking up the bm sensors onto the toy motor, wherever they need to go... that is - if thats at all possible...
As for the g-box- It will have to hold the power i throw at it... until it breaks, then ill replace... remmember, if u not breaking parts, u not making enough power...:coolShake:

"They say that life is great with a V8 --- but i would rather be blown..." i agree to a degree, turbo motors, power and sounds are always fun

then again, you could always boost that 1uz, they have been known to handle it well even on stock internals especially the beefier built early model 1uz's, so thats always an option,

1uz, 1jz, 2jz, cant go wrong with any of them in my opinion, ultimately i guess its just up to what you want,

not to difficult to get an chip to convert your signals from a 6cyl to a 8cyl or whatever, not sure how hard it is on a bmw though

1jz's have been proven to handle over 400hp with completely unopened or unmodified bottom ends and heads so if your not looking at going all out crazy it shouldn't be an issue to provide you with more then enough oomph

this is getting me excited, do it:rollsmile:

 

[spawn616]

i don't see the problem of 600hp :rollsmile:

 

[Gizmo]

If I were you I would put a stock M52B28 back into the 528i and sell it, then go buy a E39 540i as there is no replacement for displacement!

---

In fact, the money you will be saving by not doing a 2jz swap could buy you an E39 M5.

 

[JayDrft]

It is probably not going to be an easy task...

Considering the fact that you using your stock box.(Which is not a bad idea - as we know anything BMW is built for power and to last).

With your standard box in pace, it may tend to pull the 2j back into the firewall, resulting in some cutting, or hard knockn for clearance on the firewall. Another factor is the sump bulge position - this might prompt you to change the sump out to fit correctly with the current suspension and crossmember position.

Clutch wise - a 4 or 6 puck copper clutch can be obtained for a couple K, while you out sourcing the adaptor plates(Gilo Engineering in JHB).

Then the debate of the 1J or the 2J...considering the price - it doesnt mean the 1j is crap compared to the 2J....the price of the 2J is higher due to demand, but I doubt that anything will stop you from producing close to what the 2J is capable of, if you willing to throw money at it. So a 1J will also do the trick, and where you save on the motor - you can use for fuel!

Enjoy...and let us have that decision soonest and we strongly urge you to document the process, specially if you doing it yourself - if you need a hand, I offer my services, as part of the learning curve of life, in return for some learning.(you just shout if you need an extra hand, and I will be obliging).
