Engine options.

[trotty]

Ok now I won't know for sure until I do a compression test when im back in the country. But my mechanic mate has my car doin the ayc rebuild. Now he has checked the engine oil and has commented it smells like fuel. Now I will not pull this engine down if its on its way out, Ill run it till it dies.

Now the question I put to u all is if u had the ability what would u do. I have looked at some options and this is what I've decided. 1 of 3 paths.

1st. 4g63t maintaining 4wd system.
Not my preferred route but probably cheapest for outright power and ease of install

2nd. 2jz out of supra running rwd. So transmission tunnel fab work and I would probably try for an uprated LSD diff that would be bulletproof. (Suggestions on this would be nice.)

3rd. RB26tt. Same work as 2nd option.

My aim if this all goes ahead would be fastest/ most powerful legnum

As u all know I can do all the work myself. But want a motor that has ALOT of aftermarket support and reliable power. I want to chase 300-350kwatw. In a daily driver.

Let the suggestions and flaming begin. If any1 can think of any obstacles that I may come across please speak up.

Now I know the 2j has been done. So I don't see much difference in the rb. I would purchase a front cut that would supply all wireing,ecu ect ect

1st option and make it a 2.3 litre or larger.

Other 2 is a lot more work to basically make the car a commonwhore wagon

Formanth did a UOA and fuel dilution was a concern. Dont know if he will come back on the forum now that his car is sold but maybe he could elaborate a bit more.

I have spoken to Steve about it and hasn't heard of any other vr4 that have had this problem. It may not even be that bad. This could be the main reason for 5k service intervals. Fuel dilution of the oil.
I can certainly understand I'm running double the original boost so some blowsy should be expected. I did notice when I made my intake y off the maf it was filthy with oil gunk buildup.
And sleepy this will not be ur average commonwhore car. Lol.

Stroke a 4g64 to 2.6L, add oil squirters and youre away!

My head hurts just thinking about the work involved. I think your thinking into it too much and it will probably do another 100000ks lol Let us know how the comp test turns out.

Just buy a stagea if you want 300kw+

And this would bolt up to my original Gbox? I was hoping to not have to spend thousands on a forged motor.

I would prefer more work than more cost to build a motor up. That's why the rb and 2j sound so tempting. Not to mention the 2j is already 3ltr. Don't need to open motor to get the power levels I'm after.

+1

G'luck engineering any of those options. Your safest bet is a 4g63/4.
Pretty sure manufacturer states 10K oil changes. 5K is just what's been adopted in the automotive scene.

 

[Badger]

Do all 3 options and pick which one is more fun to drive lol

 

[Sleepyvr4]

Convert it to Rwd and it may as well be

I'm an engineer by trade. So the work will be more than upto spec. I don't know why ther would be a problem. I'm goin from 2.5 to 3ltrs. The car was originally turbo so that won't change. What do u see as the main hurdle in getting engineered?

I sense some disapproval?

 

[Quintenperren]

Ls1?? Haha

 

[Jakevr4]

+1 for 2jz or ls1 to truly make it a commo haha

 

[trotty]

If I was gunna go v8 I would go a toyota. 3uz-fe. But not really enough power.

 

[Jakevr4]

6g72tt pajero gearbox for Rwd

 

[Badger]

Id love to see a 2jz legnum

 

[fieldy107]

2JZ is the easiest engine to get power from but huge amount of work involved making it fit and engineering it.

I would have to make lower crossmember for engine mounts. Make gearbox support. Cut trans tunnel. And fit a stronger diff into the rear cradle keeping irs. Sounds simple enough. Lol

I know reasonably simple but have done v8 hilux conversion and fabbed all mounts before.
