how much power am i looking at? Options

[Malhar95]

so now that i have some spare time, im looking to rebuild my old 5s...

i would like some comments and suggestions:
this is what i have in mind...

1. machine block and get pistons accordingly(if necessary)
2. machine the crank
3. grind cams if injured
4. inspect valves.
5. possibly bigger fuel injectors and a new pump?

(need suggestions of which to get)

• lighter flywheel
• lighter crank pulley
• lighter crankshaft (do they make them for the celi?)

and then just bolt ons...headers, exhaust, intake, radiator etc.


lmk if i missed anything out and if something doesnt sound rite
i need some info of what and where to get them from and then some numbers ill most likely get from doing all this?

50000hp.

what compression ratio? what bore block? what pistons? what gasket thickness? how are you tuning? target AFR at WOT? what does your timing curve look like? what altitude are you going to be dyno'ing at?

1. do not get a light crank pulley. most arent balanced and will kill your engine
2. there is NO reason go upgrade anything fuel related unless you turbo, or go crazy with NA mods


you're looking at a 2000-3000 rebuild there and u will gain ~15 HP at the most.

id go with high compression pistons, port and polish, bore, and performance ground cams and then i would guess you're looking at maybe an additional 50-100 HP at the crank WITH PROPER TUNING AND THE ELECTRONICS TO SUPPORT TUNING.

even then you're still running an autofailbox

You want to do this all in an auto? IMO thats a waste of time and money.
Regardless of Auto or Manual, Forced induction is the best bang for your buck when it comes to adding power.

3rd gen 3sge swap/4th gen 3sge swap or turbo your 5sfe. easy as that. Someone is making turbo kits for around $2,500. Plus you need to buy your own piggyback or standalone ecu on top of that...

well im not looking for anything fast like the gt4 honestly, i know turbo is the best thing, but then i hear that i look reliability....since this is my daily driver, i dont really wanna turbo it since im not so great when it comes to fixing car problems and then i dont wanna pay some mechanic to fix it....


thats why im thinking of doing small mods....


i was always under the impression that lighter pulley and flywheels give u around 12-15 horses?

my goal is about 145-160 to the belt? possible with just these mods?


what if i replace it with a 3gen 3s head?
