need advise on stock evo 3 engine

[virus-v6]

hi brother's,

need some advise on a stock evo 3 engine.my bro had just converted his perdana engine to a evo 3 engine.the thing is wat are the parts to be changed or install to get atleast 1.5 bar without effecting the engine with a minimal cost.tis is becoz his mechanic told him that on a stock engine if we set the boost to 1.5 bar is dangerous to the engine.is it true n plzz advise in this matter.your advise is much appreciated.thank u brothers.....

Swap EVO stock Piston and Con rod to VR4 and use 1.5metal gasket. I think this will be much safer. But ECU need to upgrade as well I don't think stock ecu can cater for 1.5bar boost. If can change the fuel pump aswell.

Upgrade the fuel system (fuel pump, injectors), ECU (management/stand alone/piggy back), boost controller, exhaust system, cooling system, forged internals & not forgetting since you mentioned "just converted", please do an overall check up first - replace all worn belts, filters, fluids, worn hoses, spark plugs/wires, and worn/leaking gaskets & all the necessary maintainance. Btw, what's your budget in the first place?!

thank u bro mines998 and hks for the advise...anyway he already replaced all the wear n tear parts such as timing belt, plugs(ngk irridium),plug cables.he is installing a e-manage too.his budget is bout 6k after the convertion.need more advise on the aftermarkets for some boost n horsie's.n most important advise on exaust systems too.thanks

in my opinion since and from experience assuming full stock condition engine all wear and tear replaced things to be changed are:
1.Fuel Pressure Regulator
2.Walbro 255lph Fuel Pump
3.Better Clutch to Hold All that New Power
4.Thick Metal Head Gasket if you can find 2mm gasket even better since evo 3 compression is high
5.ARP Head Studs very very important
6.Management (Piggyback/Standalone)
7.Stainless Steel Intercooler Piping your stock one will leak at that boost pressure(Intercooler no need change unless you want bling bling Evo 3 intercooler very efficient already)
I think thats all required for that boost pressure with a td05 16g happy boosting
If i have forgotten anything please help me fill in :rolleyes:

1.5mm metal head gasket+bigger injectors+walbro+fpr+ext w/gate+tuned emanage = less than 6k..IMHO, with these items, i believe 1.5 bar should be achievable on a 63t

i'm using 93t with stock internals but with the items mention above, i can boost 1.3bar and no prob..63t internals are much stronger than 93t..

fpr is fuel pressure regulator..

3" inlet will do

Also, bigger HP doesn't mean the car is fast. Traction & weight to ratio plays an important roll as well...

just change the muffler first because changing to stainless steel piping is very expensive almost rm1000 for a good one id rather spend that 1000 somewhere else
all you should do for now if change it to a higher flowing muffler and remove the cat con should be able to feel a difference already

how about RVR internals?? is it the same as evo 3's???

conrod and crank should be the same just the pistons you need to check the code if you happen to do a top overhaul this can be easily spotted on the top of the pistons
for example:
evo3 piston 63DT EV
vr4 pistons 63DT
