Since the ID and OD of the 2JZ springs are different,you might want to use the 2JZ retainers. You don't want those springs "wobbling".

What about using springs from a 2UZ or VVTi 1UZ/3UZ? If I have time @ work I'll try pulling specs on those model springs.

Just a thought... I wonder if there are any "Beehive Springs" that might fit our cars. I've heard great tales about these, mostly from LS1 guys.......

2 potential advantages.

For FI engines the heavier spring tension will overcome some of the lost tension due to the pressure of the intake system. If you're running 20lb boost the back of the valves have 20lb pressure on them all the time. This means an 80lb spring only has 60lb of effective tension. 80 - 20 = 60.

The second for all engines is it will fend off valve float until higher revs. They can also help down low with steep cam ramps in keeping the valv in contact with the follower.
