Eclipse GS--n00b
I have a 97 eclipse GS 420a motor. I wanna slap a 18g or 20g turbo on it. My question is does the 420a have forged internals and if not how important is it for me to get forged internals if i only want around 320 hp? I'm a V8 guy and new to turbos so any info will help! thanks!

Whoa. No, the 420a does not have forged internals.
Very important, lol. 320hp might not sound like a lot if you're a V8 guy, but you're almost tripling the stock hp. We make around 140hp stock. There's a LOT you need to convert, but it's VERY doable. Lemme see if I can scrounge up some info!

"On to a list of things you should do to build your 420 for pressure. This does not include machining of the block/head and/or labor:
Stronger connecting rods------------------------Air fuel controller (AFC) or some other type of tuning device
Stronger pistons and rings-----------------------Larger fuel injectors
Metal head gasket---------------------------------Larger fuel pump
ARP head studs can’t hurt------------------------High flow exhaust
- (for a lower hp build you can use bolts)-------Fuel management unit (FMU) a 1:1 fuel pressure regulator is best(AFPR)
Turbo charger--------------------------------------Turbo manifold to fit your turbo
Oil lines---------------------------------------------Coolant lines depending on your turbo
Down pipe or O2 housing-------------------------Wastegate if not internal
Blow off valve (BOV)------------------------------Boost gauge
Boost controller------------------------------------MAP sensor check valve (missing link)
(if higher boost is desired)
new rod and main bearings
Suggestions
Upgraded ignition system-------------------------Vacuum line
Light weight crank pulley-------------------------Copper 110 exhaust gaskets
new oil pump--------------------------------------new O2 sensors
turbo timer ----------------------------------------new water pump
timing belt, pulleys, tensioner--------------------new seals
Intercooler-----------------------------------------Charge pipes"
