Does anyone know FOR SURE what the engine code for the Infiniti J30 is? I have several sites telling me it's DOHC, while this site http://www.freshalloy.com/cars/nissa...n_engines.html says it's a VG? Just thought it might be a good engine swap possibility based on it's 210 hp. Has this ever been discussed before - if so, please excuse my ignorance...

What size socket will I need to remove my crank pulley when I replace my timing belt?

Is an under drive pully worth the cost? If I get one, I seem to remember reading I'll need to use a different timing belt - if so, what belt? Seeing as this will be my first timing belt replacement effort, will an under drive pulley and different belt dramatically increase my risk of failure - in other words...., is it MUCH more difficult to do?

I know that's a lot, but I appreciate the input and insight you guys offer. Thanks.

both sites are right it is dohc and vg its a vg30de like used in the 300zx

Yeah..., I see that now. Was previously under the impression that the VE was the DOHC and VG was always SOHC - guess that's not the case tho (learn something new every day....)
I'll have to do some more research into compression and such, but in theory, I wonder if a timing belt, heads, computer swap would be all that's needed to get a stock VG to 210 hp??? Man......, that would be nice...
Doubt it'd be that easy tho....

unfortunately it's not that easy...the compression ratio of the vg30de is larger and then we have the issue of converting from sohc to dohc.
on a positive note: i've heard that the infinti j-30 with that engine had tonnes of problems with flooding. that's definately not an issue with the vg30e.
