i would say about 20 to 30 hp gain and noticeably better mileage :top:
if you're staying n/a save yourself the money and keep the stock catback. it has great mandrel bends and if you're not boosting you won't gain anything from a larger catback. i would suggest cutting the muffler out and welding in a magnaflow :top:
and instead put your money into a y-pipe! our stock y-pipes are complete garbage :thumbdown: they have bad kinks in the bends and the piping isn't the same size all the way through. the cats are also restrictive
and lastly if you have any un-wanted rasp or its just too loud for your liking weld a second muffler or vibrant ultra quiet resonator into the catback just after the y-pipe :top:

The only reason i have an upgraded fuel pump is because it was time to change the filter. And the upgraded in-line one from URD is cheaper than the stock in-tank one that Toyota sells. By far...

No gains whatsoever, that's not why u would want to replace it. The stock fuel pump filter can only be replaced as a whole unit that is over $400, when u use a Walbro 255 pump upgrade not only will u be upping the amount it could pump but ur also adding a new external filter that u can change regularly
Awesome information! Thanks so much. Question, probably a dumb one, but, when you replace the stock fuel pump with something like the Walbro 255 does the old stock one have to be removed? Also, what kind of other go fast goodies do you have sixstringdave?
Oh yeah, any other items to add to these N/A trucks to make them produce more power

The stock pump should be removed.
The other 2 goodies i was referring to would be my Hayden electric fan and the NST crank pulley i got. They dont add any HP, but free up the HP the engine already has from parasitic loss.

Torspd, that's some more good concrete info. I am coming to the conclusion that the N/A trucks can get up to 230 to 240+ hp with simple bolt on parts. Much above that and you have to go internals, porting polishing etc., of forced induction. Pretty much anyway you go = $$$

Welcome, exhaust cam gears, or exhaust cams are a pretty simple swap. Just need down time if you have cams done. But, there is no data on how much would be gained by exhaust cams alone. Heck, even a full set of cams for that matter.

Yep I have the TTC cams stage II, but were way radical for the truck without a tune, it missed a lot so I`ve been working on a EMS for a while... well 09 problems pin harness and VVTI. I think finally got a Pro efi 128 with custom harness for a Tacoma 1gr and maybe it will be in this week, will let you know about progress.
I had 241 rwhp without cams, valvetrain or fuel lines done to larger diameter, ssteel braided lines with in line fuel filter and 300 lph pump, also added a return line .......and a fuel pressure regulator and 1000cc injectors all from Dezod, we will see how much NA hp with gas and with cane juice looking for 300.

So did you get the cam shafts that they are offering or cam gears just to clarify for me also did you get valve springs as well? I've been thinking of getting a set of these for a while now as we'll as a uconn. Maybe a new intake mani as well. Strictly n/a build, I'm just on the fence about it though as not a whole lot of people have went this route and most have ran into a few issues.

Yeah I got the 4 cams and springs but no need for cam gears on the 09, they are Variable Valve Timing, on the 08 you need the cam gears as well, which the Ucon offers along with Thermostat.
Get the intake spacer from NST it is proven to make hp and torque its affordable also DTLTH and TCAI are a must for NA build

Yeah I got the intake mani spacer, afe stage 2si, jba lt's, 3" urd cb. To further my n/a build I have been thinking of the cam shafts and valve spring w/ the uconn and cam gears. And finish it up w/ a urd y pipe and new intake mani possibly if they become avail. We will see.
Another part of this decision that is holding me up is down time for x, install difficulty and technicality, and cost. Lol. I'm already on motor two so I'd like to do it but do it right.
If I don't go this route I may just go for the Trd sc,uconn, wal255, and y pipe, bbk.
Not sure what to do. I think the Trd sc would be simpler and overall easier more cost effective route. Hmmm. Hmmm???????
