okay... so i have my spare G180 block, pistons, rods, blah blah blah... spare g180 head all that..
i really want to build it up as a turbo motor for a swap to the luv when done.
before anyone starts throwing out swap in this or that... i want to keep it 4wd. which is why i want to build the g180 up. if i pick up a 2wd at some point i will start considering some intense swaps... supra 1jz twin turbo... mazda 13bt rotary.. but for now its the g180
im weighing my options and trying to decide the best route. i picked up a second job today so im gonna be investing more in the luv soon
okay i am NOT an expert & i HAVE NOT spent years building engines and havent had the time in my life to become all knowing and wise about all of this... so im asking for some info from someone one who is and has.
I THINK the way i should go is this:
**Block**
*G180 block. just cuz i already have one.. maybe a tiny bit of decking to make sure it has a perfect surface to keep my head gasket lasting longer.
**Head**
*G200 head (bigger valves, and lower compression to allow higher boost level)
OR... take my spare G180 head to my uncles milling machine do an angled valve job and port it a bit... does anyone know the difference between g180/180 head and 180/200 head compression is???
what valve springs should i be using if i run boost? will the stock ones hold out or should i be looking for something like a 350 spring?
*reground cam. not sure on what the specs will need to be but that bridge will come when it comes.
**Manifolds**
*custom fab'd intake and exhaust manifolds
*[thinking about using fuel injectors, throttle body, sensors and harness off a boosted civic my buddy has sittin in his garage to make a custom EFI manifold with a bit more equal length between the inlet and the individual cylinders.
not sure what the best setup is going to be. any advice would be appreciated.
*i learned how to make a turbo exhaust header from Ozgemini.com going to go for an external wastegate. depending on the turbo i find. i will make a manifold for whichever turbo i get.
**Turbo Setup**
*T25-T28 or T3/T4 turbocharger (or something in that approx size range)set at about 10 PSI boost or so. depending on tuning. im sure it will be higher when im done.
then plumb the BOV and the wastegate to dump into the downpipe for a bit more stealth
front or side mount intercooler. havent decided yet.. side mount has some good potential mounting spots but front could go low with no problem.
**ETC**
*Oil cooler to help keep everything running well longer. as well as heat wrapping and whatever effective engine bay heat protection and added air flow i can get. hood vents?
im trying to make this setup as cheap as i can while still having a significant increase in power and still keep it reliable.
im fairly new to the whole performance engine thing.. im used to my motocross bikes which come factory tuned out for balls to the wall power. but i get the principle and the limits of the stock engine. which is why i wanna boost it!!!
