^^^ The R34 Neo turbo is by far the most responsive turbo of any Nissan oem turbo, as it has a lightweight nylon impeller.

If you were going to change to a Series 2 R33 turbo expecting less lag, you would be very sorely disappointed.

How is that so?

The R33 Series 2 Turbo has a nylon compressor wheel and a 2IU rear housing

The R34 Neo Turbo has a nylon compressor wheel and the bigger OP6 rear housing

So then in theory the R33 Series 2 Turbo should spool up quicker but run out of puff much quicker than the R34 Neo turbo. This is why for those looking for the perfect balance between response and top end power the R34 Neo Turbo is the best upgrade for a RB20 when chasing good top end power (it doesn't run out of puff) whilst still retaining reasonable down low torque. The R33 Series 2 Turbo is the best upgrade for RB20 owners who still want the response of their stock turbos but a decent upgrade in mid/top end power.

I have driven both combinations and prefer the R34 Neo turbo as its still very responsive but makes tyre shredding power and torque. I have to admit the R33 Series 2 turbo is still a awesome upgrade but just doesn't have that punch. All been said any other these turbos are a great budget upgrade for a RB20.

Im not really a fan of the VG30 turbo as they are getting very old and hard to find one in good nick these days that hasn't been thrashed out. They are also a little laggy compared to the above options but still make decent top end power.
