    Are you planning to turbo the 420a? The stock internals can't handle more than 6 psi boost.

    You'll need forged internals and MS II

    With the 420? How bout the gst? Think I’m going for it instead. Kinda want awd but damn it’s hard to find a good one without breaking bank twice

    For the GST you'll need link instead of MS II, and I'd still upgrade the internals to be safe. I bet they could handle 400 crank hp, but to the wheels you'll need an upgrade. But even with the crank hp they"ll get fried after some time

    I follow Miguels DSM. It is NOT an easy swap. Custom drive shaft, hard to find EVO ? front axles, cut and weld front sub frame for tcase clearance and fab rear engine mount. There's probable other stuff that I'm forgetting.

    I believe he was referring to the 420a->4g63t swap not the 420a->awd and 4g63t

    Either way requires fab work, and is not for beginners or low budget builders.

    This is everything you need to make a EVO 8 swap with the 420a engine


    MOTOR: -Evo 8 engine -Front,rear and passenger side 420a mounts - EVO HKS 272 cams - ARP head studs - Powder coated valve cover - Oil drain line gasket - Cam Seals - OEM Water pump pulley - OEM timing tensioner pulley - OEM timing belt pulley - OEM timing belt - OEM balance shaft belt - OEM belt tensioner - OEM water pump - OEM idler pulley - AC delete belt - Valve Cover gasket - Cam gear bolts - NGK BPR7ES Spark plugs - Mobil 1 Oil Synthetic 10W-30 - OEM Oil filter - Manifold Spacer - Rack and Pinon/Oil cooler bolts - Auto relay fuel pump rewire - SS fuel feed line - Evo 8 rear main seal



    DRIVETRAIN: - 3g Eclipse trans (2.4L) -3G axles - 3G transmission plate - 3G lower transmission plate - 3G trans bolts - 3G motor mount bolts - Evo 8 flywheel bolts - 420a mount inserts - 3G trans mount - 3G slave cylinder - 3G shifter cables bracket - Pennzoil trans fluid - shifter cables 2g and 3000gt - 3G starter - 3G Clutchmasters Fx400 clutch - 3G Clutchmasters flywheel

    GENERAL: - ETS FMIC piping - Turbo gasket - O2 gasket -Down pipe - EGR delete plate - Evo 8 alternator - Tubular manifold -Heat wrap - Maf/adapter - AEM intake -Punishment Racing FMIC - Greddy type S BOV - Evo 9 turbo - Evo 8 Mishimoto half radiator - Mishimoto Slim Fans -Fuel lines - Hallman boost controller - AEM Boost gauge - AEM Air fuel gauge -Fuel lab

    FUEL: -DeatschWerks 415LPH High Flow In Tank Fuel Pump Kit Eclipse/Talon 420a fuel pump - FIC 1200cc injectors -Base Map/Tune


    Just a basis of what is needed to do the swap from 420a to EVO 8 without a lot of fabrication (some fab still needed but not nearly as much)

    Half of that stuff is optional. Also not sure why you included brands, as any brand of the same part will work.
