VG33 vs. VG34

[SleeperZ31]

Okay now that ive been informed of the process to buildup a VG34 i want to know if anyone thinks the extra 100cc's of displacement are worth the effort!

 

Im just looking for a good N/A motor to build for my 1987 300zx and im looking through the idea of cost-efficency vs power output, ive heard good things about the 3.3l mill and i honestly dont think the .1 liter extra displacement would make all that much of a difference, and considering the weight of the engines internals has an effect on (especially) N/A motors and the fact that overbored motors usually have lower redlines (correct?) and are more prone to failures than normal motors im stuck between a rock and a hard place (mainly my budget) im not going to build a "cheap" motor by any means, i'll use the best i can get and follow the book without shortcutting anything, i just dont want to spend a ton on custom work to get the VH45 pistons in place and working if it turns out it wasnt worth the time or I could have spent my money more efficently.

 

Im definently going to choose the VG33 as my next project but i just need some input as to whether or not the VG34 is a worthwhile project or if i should just stick with 3.3l and see what i can get..This is going to be strictly a street and sometimes strip motor (and car) i dont condone street racing at all but im always up for a little spirited driving!

 

Also, ive heard of specific coatings for cylinder walls and pistons that can help out N/A motors by increasing efficency, has anyone tried such a thing? I know to avoid Nikasil due to manufactuor recalls but I just thought maybe it might be worth a shot, i'll consider anything that can help lay down bigger numbers without the use of forced induction or NoS

 

Thanks again to all the HybridZ experts for all the help and advice over the past few months and i'm open to any and all constructive criticism
