1jzge/2jzge experts please

Took my 1995 130 Crown wagon up to Auckland handles way better with new shocks; but the factory non-VVTI 2.5 n/a 1j is slow as shit... The wagons too heavy for it. I'm keen on the idea of throwing a 2jzge in there; the 3.0 will make the wagon get along a lot nicer and turn it into a nice cruiser. And Don't  want to go down the 2jzgte track, So there's a low km non VVTI 2j n/a on TM for sale for $2500 from a JZZ31 94 soarer... Or 1500 without ancillaries... Questions I have is:

1) will the 1j ancillaries bolt onto the 2j?

2)will the 1j ECU run the 2j?

3) do I need a cert for the swap?

anything else I need to consider in what appears to be a straightforward case swapping the sumps and dropping it in???

Cert will be required, driveshaft hoops may also be required.

If you're going to the effort of replacing the engine, at least get a VVTi engine.

Will it be much harder to drop in a VVTI into a non VVTI wiring wise?

[Yowzer]

As long as you have a complete loom and computer it shouldn't be too bad.

Is there something wrong with the 1J? Surely it should boogy the wagon along no worries. If you want a slug, try an NA diesel.

Yeah E1 TE1 that thing and see if it chucks some codes

Nah there's nothing wrong with it; I've had n/a 1J Crowns before; they will get going if you push them but I've also had a 2j 155 Crown and that had loads of power; just would like the wagon to get along better and have the engine they shoulda thrown in from the factory. Probably get better mileage too.

How much more power do the VVTI's put out in relation to the non-VVTI?

[Yowzer]

I dunno, I think max power is still about the same but they have a much wider torque curve.

How about changing diff ratios? To get some more rpms.

I also am surprised it's as bad as you say... 

I do worry that you could spend lots of money and get fuck all gains.. why don't ya get it on a Dyno and see if hp is where it should be and ask them if they have had na 2js on there that they could compare it with.

Even a decent tunable ECU may way it up better than a swap.
