In what?

Hydrolic lifters wouldn't find it amusing,

should net a nice amount of power extra though, eith larger TB and free flowing exhaust

Its going in an rb25de neo....how much are solid lifters these days? and wat size piping you think will be best i have 2 1/4 now im thinking 2 3/4. Cheers mate

RB25 neo's already have solid lifters, not sure how much lift they can handle though. They also have crappy exhaust cams, i reckon you'll get a decent amount out of it with some cams.

As for exhuaust, its really depends how much power you think you'll get out of it... a free flowing (mandrel, good mufflers) 2.5" really should be enough to be happy at ~ <160rwkw N/A (mandrel, good mufflers etc). Not sure how much you can get out of 2.25", but i'd guess if you were making much more than ~ 135rwkw, you'd want to increase the size.

If you have future intentions for nitrous, boost, or some more serious N/A work, 2.75" wont hurt anything, just for that extra resolution (car will be happy <200rwkw).

What other mods do you have? Done anything with intake? What about management? Cams like that are going to feel fairly flat without a tune, either a piggyback that handles ignition (like emanage ultimate) or full management.

is the 2.25" mandrel bent?

If not, I wouldn't change it just for the hell of it, do some other stuff first and when its tuned, your tuner should tell you if there is too much backpressure, and if its whats choking your engine.

Can emanage ultimates alter VCT? As that will definately need adjustment for cams with that duration.

But yeah, in a nutshell, your car will love those cams with the gear it has. When you get it tuned, you will see if its being choked from the intake or exaust.

If i was you, as a next mod i'd put twin throttle body's on your intake manifold, shouldnt be too hard since it has the twin input Y peice as it is.

Granted its higher capacity, but with alot milder cams (255/8.3), my 30DE with twin 60mm throttle's, uses every last bit. Also, with exaust, it had 2.5" press bent, with a 2.25" section (decat pipe), it made 150rwkw, but tapered off quickly, it always felt flat after peak power aswell, after i fitted a 3" mandrel exhaust (2.75" wasnt available) that was no longer an issue and it held power strong until limiter.

Its not mandrel bent and not sure if you can alter vct with emanage and wouldnt vct go with new cams?
