hi guy starting to build my engine so i am looking at a rb 25 VCT head

thanks in advance

Yes it will.

But you don't need to fit the TC head! The SOHC head will provide enough fasts, Loui ;)

That mod (25 vct head on 30 bottm end) is well documented on the interwebby there is a pdf you can find if you google ;)

 

As Lurch has stated you can get enough power from the single so unless you are going for the look you can leave the single cam head on for now ;)

In 8 hours I bolted on about $2000 worth of ebay/calaisturbo/R31forum parts, output of 190rwkW and 360Nm of torque..... at 10psi.... single cam RB30e FTW!

the stainles tuned length highmount manifolds surely make a difference, as well as the 'hypergear' turbo, (cheap stuff but had 12 month unlimited warranty)

This was on a mates R31 in Victoria though.....

It is a billionity times easier than turboing an L series though! Plus parts are EASY to find. My L- series setup has taken 3 years to find the right bits! (and its still not done) Shoulda just gone RB30 from the start.

 

Now I have a VG30det and Z32 5 speed sitting in the garage.... hmmm what to do
