Rb25det Neo vs Rb25det

Hey guys, new to this page, currently building a motor. I have a reb25det neo block, got some forged pistons that are rb25neo pistons, are neo pistons only compatible with a neo head or could I use a standard head with it? Cheers

Hey Bailey

Im guessing your new to forums. Mate before you get smashed can I give you some advice? 

It is etiquette to do some searching before you post up a question, use google to search this forum as it works better ?

Of course if you cant find what you need, post up. But Jesus and his deciples were toying with RB's long before you and I started playing with them so 9 times out of 10 it will have been covered 50 before.

hope I got in before the less subtle deciples just gave you both barrels

oh and you will find your answer ???

Hi mate, welcome to the site.. lots of good advice on here but lots of shit too.. if you look up most people have gone the total other way to you. People put the neo head on a non neo block for the vct and solid lifters ect ect.. so cant understand why your going opposite way? It does seem like it can be done BUT with alot of stuffing around and headaches as the tops of the pistons are different and stuff.. your best off getting the neo head to match as nissan put alot of work into the neo with the vct ect ect.. if you do end up needing a neo head please just pm me as im about to change mine over as ive just had 1 fully worked so i will have a spare soon and in perfect condition.. anyways i hope u can find what your looking for but i think most will tell you the same.. Cheers mate

You have to use a neo head. If you use a standard head with neo block the comp ratio will be way off and too low. Neo head and standard rb25det heads have different chamber volumes.

I learnt this the hard way

[Scott Black]

Yep neo chamber is heaps smaller than the non neo, so the neo pistons would lower the comp of a non neo head a stupid amount
