turbo AR

On a side note I really like your ute.. Nice work!

The s475 is a 75mm turbo from memory? (Compressor inducer size)
In my opinion anything over 360ci can really benefit from at least a 80mm turbo, T6 in the 1.00 range.
Of course the s475 will work and make plenty of power, and will definately put a smile on the dial! But a good matched turbo will produce more power easier and be more efficient.

An PT88 precision, Garrett GT4788 or borgwarner s480 would be a great match for yours, with the correct housings and trims

Only reason I have my 76mm is because I originally planned on using a 318 lol, how plans change!
But once all up and running I plan to run a PT88 and some custom headers.

The twin 50mm bovs are not really needed as such, more a cosmetic thing I wanted, but I've gone overboard with most things, bovs, 4" dump pipe, aeromotive fuel system, 2000cc injectors, 1500hp rotating assembly..All so I don't have to upgrade when the wick is turned up :)
I plan to get a Ritter block in the future and shoot for over 1000hp at the tyres.

Yep it's a ve regal sedan, have a build thread on here if you wanna search for it
