got a used Power FC kit even with a turbo timer for 450$ in Chile waiting for me should be here in the course of the next 2 weeks, anxious to develop my engine will run 1 bar of boost max, 200 miles and oil change mineral oil only, then another 800 miles and oil change, oil detergent engine cleaner and switch to synthetic 0w-30 or 10w-30 if i cant find the first. Having trouble getting CO2 since the threads doesn't match with the industrial plants feeding plug (lame I know doesn't kill them to be prepared with different sizes for different tanks) I will try at a fire extinguisher company as a friend recommended since he has NOS and CO2 in his cars, also, NOS is 500$ a pop down here...co2 is about 6 dollars a pound. I will see if I order some cheap cam gears and a 264 intake cam, and retard exhaust 6 degrees. I think I might be nearing the end of this "Cheap" build thread. the DNA cam gears are cheap I cant remember where I read you might want to change the bolts for nicer ones...
So Specs might come down to this in the end,
Engine:
Forged 3SGTE
CP Pistons 9.0:1 Compression 86mm bore std
Eagle Rods
ACL Main and Rod bearings
To do:
Cam Gears DNA
Intake 264 BC camshaft
exhaust 264 BC camshaft
Pic shows 2 for 550$ I guess if not it will only be the intake cam
Hopefully new valve springs and 1mm over valves
I want to rev to 8k rpm
Turbo:
Currently the KKR480 I want to see how much juice and reliability I can get out of this thing with the external wastegate maybe planning to run 20-24 psi depending on the AFR values I get.
Fuel System:
I have a walbro 255LPH and will use that with the stock rising rate FPR Should be enough my power goals are under 500 horsepower
750cc top feed injectors on a 8an fuel rail
cooling:
Koyo Rad alluminum
Stock W2A intercooler, run the CO2 cooler ontop of it to cool it for drag runs, will run the purge under the turbo and upwards incase of a fire I will fill the bonnet with CO2 my guess being that if oil catches fire it will be near the hot turbo and if the fuel system catches fire cutting ignition and flooding the bay with co2 will be sufficient.
Had the W2A intercooler polished and sanded again because it does not shine it is a dull color so I had it painted metallic blue (cusco color) and it is beautiful.
Suspension and Brakes:
BC Racing full coilover kit
Stock brakes with new Eagle Pads
Clutch is atm stock pressure plate with a ceramic 6 puck ACT clutch disc launches fine at 5krpm on 225s no skidding and no clutch slippage either.
engine has new seals on all corners.
Any input is appreciated this build has taught me alot of things and I hope this somehow gets stickied for any novice GT4 owners looking for quick power to learn from my mistakes. Just to name a few:
Over boosting with stock pistons and rings on a used engine around 19 psi caused major blow by and permanent smoking raised oil through the dip stick and flooded the factory catch can with oil. almost caught on fire.
No matter how much boost and Water and alky injection you put in the stock ECU pulls timing and that torque pushing you into your seat is no longer present.
Read EBAY items 5 TIMES before buying, and make sure It is for the correct GEN reguarding the head/ head gaskets etc.
When you make your budget, Multiply it times 2 and that will be amount of money you need.
Make your mechanic your best friend, if not, bust his balls until he finishes the build.
recirculating the BOV and venting to atmosphere is a personal choice.
Launch control is fun as hell, loud and I recomend an exhaust cut out (electric if possible) to avoid cops and to not blow the **** out of your muffler.
CHANGE ALLL FILTERS WHEN DOING A BUILD, You do not want any past grime getting into a brand spanking clean new engine.
