Tomei Poncams R33

[RB_purr]

Hey guys real quick question in regards to purchasing tomei poncams for an RB25DET R33 the question is which ones to get.

There are many types with different lift etc which is like reading NASA blueprints to me

Engine is a RB25DET with the usual stage 1 mods and boost tee running 14psi@187kw

Im looking for bigger power in the future but i don't want terrible idle etc and just want poncams that will work efficiently with my current power and that will also work with more power in the future

Any help on what lift etc to get would be excellent and preferably people with good knowledge on them as im looking to purchase them fairly soon as im also having some top end components machined

Cheers guys hope you all had a good christmas

You want the 256 8.5mm lift and depending on what yeat your r33 is either s1 or s2 cams up to 96 generally have the old CAS so youll get s1 model and 97 ones had newer CAS so they are s2 cams.

But, FWIW, the stock cams will do fine if you spend the same money the poncams would have cost you somewhere else, and you'll probably end up with more power (if spent on power) or more fasts (if spent on handling or brakes).

[NYTSKY]

If you have an RB25DET with the metal CAS the Poncams you want have the part number ending in 020, if you have the plastic CAS the part number ends in 050. This is for non NEO engines.

Cams will not be cost effective if you are making ~190rwkw at 14psi. No way at all.

You will need a retune to take advantage.

Since you are going to need a retune anyway then a turbo change is really the only way to make much more power. Save your money, leave stock cams and spend money on injectors, turbo and tune when you have the money.

As above, cams at this stage are nothing but a waste of money

So at what stage would one start looking at getting aftermarket cams?

Once youve done the basic bolt ons and got 250kw plus and your looking for another engine mod to help your midrange abit then u consider something like poncams.

Before then there are plenty of better ways to spend the money from diffs, tyres, brakes, suspension etc.
