Rb30det/tt Vs 2jz

[Fitzpatrick Speed Works]

Sorry if you took it to personally but have you done a 2jz conversion on a skyline?

Have you built motors?

How much experience do you have with rb's or even 2j's for that matter?

What do you do for a living, is it automotive based??

10-15k on a rb hybrid to make the same power is that besed on the fact you own a part store, or have sone these engines before?

This forum is over run by people who make statement sbased on there own opinions and no real experience (what they have read or the mates have told them) and by people who are not remotely qualified to make stupid generalisations , which is basically what this entire thread is....

Sorry to say it but it grinds my gears that theres is endless arguement about unqualified statements such as "2j head is shit" or "rb30's arent a race motor" etc... Its almost to the point where you most people with true knowledge (not saying myself by any stretch) are turned away cause they are sick to death of the dribble.

Just read my thread looks like I am having a massive go at you, sorry mate, not my intention. Seroiusly though all i ask for is when people make statements they qualify there statement with experience and genuine facts that is all, sure it is a discussion forum and people have a right to opinion and heresay, all people need to do though is make it clear when this is the case!!!

$4,500 for a 2J

Then the gearbox. Priced the good 6 speed boxes for a 2J, they're nearly that price again.

Then get all new mounts and everything made, and then, since it's not the original motor in the skyline, around another $1000-$1500 or so for an engineers cert.

I'd be assuming the 6 speed box for the 2J has now come down from 6G (Where it was around 3 years ago) to a price of around $4000

So that's $8 500 JUST for an engine and gearbox, no mounts, nothing, not even in the car, you haven't even put a new turbo or anything on it.

So, looking at $9 500 basically (Excluding labour and engine mounts) to put a 2J in your R33.

You said $10 000 to $15 000 for an RB26/30 combo? I'll go a 26/30 combo then. As for $10 000 - $15 000 that's all new turbo, manifolds, injectors, etc, whereas, your 2J is still on stock turbos.

He's got a choice - spend well over $10,000 on a RB26\30 or spend less than that for a motor that can do the same, standard setup.

You can get a well built bottom end be it rb25/26 or 30 for around 3k. Drop in a set of forged pistons and rods, thats bumps the price up to 5k. Cams and springs, 6.5k. Add an ati balancer - 7.5k.

Unsure with the 26's but the 30's have issues with more than 7500rpm when making 700hp, the stock girdle needs beefing up.

I know of a 2jz that just let go with ~450rwkw. Smashed ring lands.

It is thrashed daily, especially on the weekends.

I bet that wasn't the engines fault...

Well, I had no idea that the person wanted to purchase the engine to put into a skyline.

But unless the car is already a GTR, there is still a lot to do fitting wise.

It was fine for months and months prior..

Just one of those 'street' things. Could have been poor fuel + the weather is a touch warm etc etc..

the exhaust on 2j is on the other side of the engine bay could foul steering.
