whanting to crack the 400bhp barrier so ithink ill need greys 403s is it best to buy second hand or buy new???

 

you would be better going for Siemens injectors mate,83Lb/hr flow rate is good for that kind of power and all the good tuners can map them no probs on L8/P8........They have a very good resolution compared to a grey and can be made to run very economical on closed loop systems....

 

What Turbo more importantly???

 

Damo V
it a stage 3 t34 hybrid sama as yours ithink???

 

will struggle with 400 brake ... 380 ish ideally

 

so what turbo would you go for????and GT may be???

 

Probably the T38 hybrid thing

but then to get the most out of it you will need headwork and a cam

 

Surely if yuor spending that much on an engine build, you'd buy new ones, if only for peace of mind?? - how much is a set, inc a fitting kit?- 300 quid max???

 

Dont think he is rebuilding yet..
