3RZ Power upgrades?

Howdy guys. I have a 2003 4x4 SR5 with a 3RZ 4 cylinder. I want to eventually make it a mud/offroad truck. I like the 4 cyinder because it is light weight and i think it may give me an advantage to some of those V8 knuckle heads....If it had a little more power. I have a couple ideas i just need some direction.

-Turbo with bigger fuel pump and injectors?
-Supercharger?
-N/A with fuel pump, injectors, headers, chip?
-Gears

Or any other suggestions would be greatly appreciated thanks

 

i recommend getting a new exhaust as in full catback and everything with a high flow muffler, i really like my K&N CAI on my 4 cyl would recommend def, and i'm looking into a new header for some increased lower end power. Or if you have $4000 dollars on hand then go with the supercharger haha

 

I threw a flowmaster in her and did the deckplate mod (poor mans CAI). It makes it so i can climb most hills in 4th with 32s!

 

yea the deck plate really does seem to provide some good results, close to most CAI. But i love the quality of my K&N intake and it does add throttle response for sure. Did you get a better drop in filter since you put in the deckplate? Cuz that makes an even bigger difference. And i also have a flowmaster i think they really sound good on the 2.7, can't even tell it's a 4 banger haha

 

well chris i know you are the guru on here but i have no doubt that my K&N CAI added some power, it said more my truck it would add about 7 HP which isn't much but i noticed a def increase in throttle response and i don't have to downshift for hills that i always had to before install. Which one did you dyno? Cuz i think i have the 53 series idk but it's the FIPK kind not the air charger series

 

ok i get where your coming from chris, but isn't that the point then, to build the HP quicker and thus create a quicker acceleration and once that HP is built up it is maintained so that's why i would be able to make it up the hill now without downshifting right?

Or am i completlely missing the point and talking out of my ass? haha

 

im suprised chris4X4 hasnt told u to go with the tri-y header for ur 2.7. thats what ill be getting as soon as i can get the extra $$ for it! i'll have my afe pro dry s air filter in a few days, i can pm u about it! i did the deck plate mod, & then about 2 weeks later took the intake resonator thingy off as well, & i can tell quiet a bit of difference in my truck!

 

very true with the placebo, and i would prob think i would have gotten ripped off if it wasn't for the hill and downshifting cuz there is no real way to tell if your acceleration or whatever has improved on a flat street especially with the sound of an intake cuz it's louder and cooler so therefore it must be faster haha or atleast that's what my teenage mind would tell me lol. But i'm still impressed with it, and i'm waiting till monday so i can call those guys at North West Off Road bout that header haha

 

i called them, they said they had a few left in stock, they r a bit pricy, but it would be worth the extra for the gain.

 

how much were they???

 

like $514.95 + shipping, pretty sure thats what he told me, been about 2 weeks ago!

 

holy shit! i think i may just go with the DT LT then cuz their only like 250 from URD and i'm sure the NWOR would be better but idt they'd be $250 better haha

 

yeah, steep for it, but ill just keep saving for it, i reckon. thats y i was going to try the pacesetter header for a $170, just to see, but ill stick with the tri-y!
