im turboing my 420a ....wat all do i need besides turbo, front mount, o2 housing, piping, n BOV? i dnt plan on running anthing over 7 lbs of boost till i build the engine so i just need the basic don get all fancy pls....n yea i kno its a 420a i dont care if ur gonna talk shit dont write anything at all

 

you are going to need oil feed lines also and a boost gauge, turbo manifold. good luck with it. have anymore questions just ask. ill be happy to help out!

 

Probably need some kind of AFC since your stock MAF might get angry. Maybe at least some 450cc injectors?

 

i would recoment apr head studs and a metal head gasket since you're already there.

 

RS/GS models dont use a MAF, they use a MAP sensor. You'll need an FCD or a missing link to keep the MAP from seeing boost. 450's won't work without a resistor pack. 7PSI can be achieved with a 12:1 FMU on stock injectors, (Cheapest) but you'll need a Walbro 255HP model fuel pump. Also your injectors will be nearing 80-90% duty cycle with a 12:1 increase in pressure. An SFMU is more ideal, then you can utilize 450's with a resistor pack and run a little more boost. (Provided you're not using OEM internals.)

You'll need an oil feed / return setup. You'll need to weld a bung in to your oil pan for the return. You can tee off of the OPSU location for the feed.

Obviously things like a turbo manifold, BOV, boost gauge, aftermarket oil pressure gauge / sender, and EGT gauge (I cannot stress this one enough.) Wideband is always nice, but at 7PSI you can forego it if necessary. Unless you're planning on an SFMU and 450's; As it becomes necessary at that point.

An AFC is a moot point at that level; If you're going to tune it either go with Megasquirt or a PortFueler.

 

i don't know if you'll run into this problem like i do but you'll also need money

boost is like a good whore. it's expensive but you want to keep hitting it

 

ok ima have 16g turbo dump pipe n manifold this friday...ima have o2 housing ,wastegate, fmic ,BOV n piping in 2 weeks any kno a good place to get the oil feed lines? n does it matter what size wastegate i have? and is 7 psi gonna be ok on my stock internals until i start to build i dnt plan on running it until then either..

 

lol you were being an ass before anyone even had the chance to be one for you. so.. dude its only a 420a!

I personally would NOT run a metal head gasket on that car with a stock bottom end. it's better to blow a head gasket then destroy a bottom end. something has got to give, a head gasket is the fuse.
