2001 Tundra Cab swap 5vz to 2uz

Long tubes ultimately will make more power. But shorties will provide a bit more than long in the bottom end

 

Gibson GP603 .... would this be a good fit for me ?

 

My google fu seems to indicate those will work. You'll want to buy new gaskets. Tagging a few people that have done the job to see which gaskets they went with. @imDementeD @Darkness @Thrussn

 

Percy's header gaskets for the manifolds. Looks like they are also going by Taylor Cable as a name. You can look for Percy's 66080

Remflex #8015 I believe is this one for the collector

Also you'll want 22 new locking nuts from Toyota, a few spare studs wouldn't hurt in case yours break. You need 8 nuts per manifold and 3 nuts per collector. Might need 3 bolts per collector too, I can't remember.

 

I used remflex for the header gasket and it did fantastic. I'm going to use them again when I reinstall another header this weekend because I keep breaking my JBA shorty. I would recommend them for the collector gasket too. I'm ordering some as I type this lol.

 

i almost ordered the gibson set but seen it was only for 2wd. Thrussn why do u keep breaking the jba headers ?

 

Are those Percy's/Taylor Cable gaskets better than OEM Toyota or just cheaper? I bought OEM gaskets for about $55 for the Doug Thorley headers.

 

I've never used oem ones but when I did my headers and compared the two, the oem were pretty flimsy compared to Percy's. I think the Percy's have a little more room to compensate for any gaps between the head and flange.

I haven't heard any complaints on oem gaskets either, they should work.

 

Went OEM gaskets. Originally OEM at the header and JBA at the collector that leaked and replaced with OEM.

 

I ordered new body mounts from the dealership. also changed the fuel filter i was stressing over that one. Because we have the v6 gas tank we needed to swap fuel pumps

 

That is no small amount of work. Congrats on some quality work so far! I just spent an arm a leg and several months on an Outback XT manual trans rebuild. Every time I turned around there was a “While I’m in here I might as well ...” project. That line of thinking will double your time to finish but in the end you have a vision and you should see it through! I can’t wait to see your finished product, good luck!

 

how did that go? I'm wondering how difficult the fuel line fittings were to break loose?

Fantastic work so far..

 

used vice grips instead of wrenches but its on

 

funny with the suby man i have that same car

 

How’d the gasket on the Fuel Pump to Tank Lid look?

 

Ha! Yep same model as well. Are you on legacygt.com? I had a 2005 lgt and now an 06 OBXT.

Great minds and all that.

 

good to know. Thats on my list for next spring.

 

not really my car has a ej20x i was asking about that on one of them sites

 

thats actually supposed to be the next project on the list i have it running but i need to learn some tuning so she doesnt pop

 

the fuel pump gasket was reuseable i have 2 options for alot of parts so that does help

 

Ordered a set of doug thorley headers from urd racing. I do have a few lose ends but i am getting close to being about to install the cab. Hopefully in a week or 10 days i will have most things sorted.

Same place I ordered mine from

 

Dan, do you have quick tips to where I can find all the unhooking places for the dash... maybe a link to instructions-? I don’t have a proper manual for my 2002 that covers this.

 

I’ll check when I’m home. I’m at work currently

 

Back to no hurry, ran into a problem I can’t fix immediately, so this can wait.

 

Well guys life got in the way of progress on my old pickup truck. It was a huge mess dealing with the manifolds. I broken studs mangled treads in the heads u name it lol ..... that stuff gets me super worked up half the reason for avoiding it lol

 

Yeah. That Driver Side will break your Spirit if you let it. Spent 18 hours tucked up in the wheel well last week. Two Mangled Studs and one stuck stud (left it on and it came back to haunt me on Manifold put back but prevailed over it again with Hand Mojo). No broken Studs on mine.

How did you get your broken studs off? That had to be disheartening.

 

I feel your pain. Just remember there are guys that have rebuilt engines with lots of go fast parts and left a block plug out and roasted the whole thing while doing cam break in.

Just some perspective. I need the reminder sometimes too. I have an awesome track record of making a level 5 project cost as much and take as much time as a solid 10.

 

I just can’t finish a project

 

new nuts...... boy i guess i am doing something wrong lol. The local toyota dealer wanted over 600 dollars for 16 studs and 22 nuts I about fell over. I ended up doing an online order from dealership that was not price gouging was about 230 or so i believe. i honestly dont understand how these dealerships can charge over double the listed msrp prices but i guess it happens everyday.
