hello..sorry my english but i m italian.
I would like to ask you some questions..
i have an evo 7 stock block,i would like to a big turbos precision 5858..it's a good idea?
I want to structure it so:
manifold full race wga tial 44mm (v band) precision turbo 5858 v band 25psi?
cams gsc s2
injector 1000cc
greenspeed solenoid
arp rod bolts
intercooler hks type r
exhaust 76mm

say that the head gasket keeps? it's possibile? (25psi)??
my evo has 100.000 km
Also replace belts and water pump

thanks for answers..

 

A 5858 has been done on the stock block many times. Just keep the torque down and you'll be fine. A good set of ARP head studs wouldn't hurt either. A buddy of mine has 90k miles, or 150,000km, on his stock block Evo IX and he just put a precision 6266 on it and made almost 600whp. Get a better intercooler than the HKS though. Look into ETS, AMS, AGP, etc. and get a full 3 inch exhaust, if I'm not mistaken 76mm is a little less than that.

 

thanks for your answer,
how much torque can I do?
for the pressure I have no problems?

I would not want a rod that comes out or jumping in the air head

 

Keep it under 400wtq and you'll be fine

 

Check my sig. Fun car! Good luck man!

 

You have no sig

 

Haha, Sometimes it shows up don't get it man.
