estimating future power on my N/A

im wanting to bore out my N/A block as much as possible, maybe port/polish my heads or vr4 heads, racing cams/gears, ferrea racing valves...i really dont want to swap to the 6g74 or make it forced induction at the moment,,,,,if i do these upgrades what kindof power would i have?

hey im just wondering, why do you plan on spending all that money to stay n/a, is it because of the maintenance of forced induction? because with that kinda money you're lookin at, you can accomplish a whole lot more going forced induction

im not sure on numbers but with all those mods you will definitely gain a good amount of power, but the way i see it is your eventually gonna just hit a dead end where you cant do much else to your n/a, whereas with turbos it seems neverending

well yea i heard the upkeep on vr4's can be quite expensive, and i dont want outrageous amounts of power on this car in particular, it does a lil over 150mph right now stock, i would like just a lil mor power......i plan on oneday buying a vr4 spyder which i will make into a monster...but at this time i just want to upgrade my N/A

its hard to give numbers on that... but i'd say maybe a 50-60 hp increase... jus estimating... so once thats done... throw a 75 shot of nos on there, and blow a stock VR4 outta the water :P maybe...

you have dohc right?

intake, full exhaust, underdrive pulley, 75 shot Nitrous, used SAFC controller and you will have easily over 110 hp under your belt, and you will only have to spend under 2 grand, but you wont need to spend all that money on performance cams and gears, racing valves, port and polish, vr4 heads, because you looking at least if not more than 6 grand just for that with labor, screw that spend the money on what i said and you'll have more money to save for that VR4 Spyder and with these mods still be able to take on stock vr4's no sweat at all from a roll ...

yea, its a DOHC....thanks alot for the help guys

keeping the N/A is going to be expensive on any car. i'm planning on doing a twin turbo conversion myself. i think the outcome of a forced induction on a fwd, compared to the n/a is more worth the cost.

To get peak power out of the n/a you have to considder a full through route.
new intake, ported n polished heads, head work, bored cylinders, higher compression pistons, new connecting rods, a balanced crank, new clutch/flywheel, i would remove the cats, only because i live where theres no emissions test, to a tanabe or borla exhaust, only for a maxed out 150 hp.

Also, the higher compression pistons will be a bitch trying to run on pump gas.

BTW i would not get that spyder. the vr-4 is heavy enough already.
