I have a 4x4 saff with 400bhp and was thinking of taking it to over 500 with a T-4 ect because i really like top end power.
It has grey injectors and fully ported head, long stud and all the usual.Im thinking of doing the work myself if poss and then having it dynoed and mapped.

Basically im just trying to get a rough idea of what extra work will need to be done to the engine.And of course what box will it need bearing in mind it wont be launched.

Cheers for any advice.

 

-Injectors
-2wd exhaust manifold
-turbo
-suitable mapping

 

400 BHP

 

maybe diff, brakes, box.......oh and loads of money

 

will need a strong gearbox with out dout, might be an idea to get a set of air injectors as well

 

100 shot of NOS

 

gearbox/diffs
different cams ( probably be easier to go straight for a touring car spec head)
multilayer WRC head gasket
uprated fuel pump
new loom ( wouldn't risk running on original wiring )

plus all of the above and probably more
