OEM mini header install for 2.7L*(Pics)*

96redtoy · 10-27-2008, 05:55 PM

So this all started the other day when I was driving down the road with the windows down and the music off.

I was driving past some of those concrete highway dividers and heard the tell tail sign of a exhaust leak - tick tick tick

after further lissening (standing next to truck as some one drove) it was true

Since I have the 2.7L I knew it was the manifold.

After a brief time and a few choice words I found this-

heat sheild

the crack

I will be getting the exhaust mainfold from a 01+ 2.7L
they are like a mini header that bolt right up to the factory down pipe

part# 17141-75080 this is a direct bolt on they run around $150 from the dealer

Here are some pics of this manifold not on my truck-

I will be posting more picture as I go step by step

Those are cool! I want mini-headers for my 22re

**DeathCougar** · 10-27-2008, 06:33 PM

You caught that crack at the perfect time. I have seen manifolds cracked completely in HALF! Apparently people don't understand how bad exhaust leaks can be...ie suck a valve!

Thats a good swap idea on the 2.7L manifold. Definetly do a swap, and talk to Corey about making it a sticky. It my be a permanent fix to the terribly designed 2.7/2.4 manifold design.

96redtoy · 10-27-2008, 07:00 PM

Will talk to Corey about this swap becoming a Sticky

yeah they are the best replacment in my mind because -
they are going to seal and stay sealed
toyota made them

they flow better then the old ones
complete bolt up

TTORA has a lot of info over there on this swap

96redtoy · 10-28-2008, 04:31 PM

Went to the stealership and got a quote for $265 which is crazy. Everybody that has done this over on TTORA say 150-180 out the door at there stealership so now I am going to start calling around to find a used one.

**DeathCougar** · 10-28-2008, 06:51 PM

If they told you $150, they were simply NOT using Factory toyota parts from the dealer.

List price on that manifold from toyota is $227. $265 is still way too high, so talk to Strap22 on here and get a discounted price!

Or just go to that link I sent you above.

96redtoy · 10-29-2008, 09:26 AM

Thanks alot DC

That linked price is much better

Are those a OEM part or some knock offs that will not seal what so ever.

**DeathCougar** · 10-29-2008, 10:02 AM

Those are OEM factory parts, from Toyota of Dallas.

96redtoy · 10-29-2008, 10:14 AM

Thanks alot that is what I thought

CDUFF7 · 10-30-2008, 09:05 AM

I want one too!!!!!

96redtoy · 10-30-2008, 01:56 PM

just order from linked above

emailed them and whithin 30mins got a reply that somebody actually wrote and was very helpful

great website will use them again

I'm in the market for a mini-header upgrade for my 2000 4runner. I was planning to upgrade the rest of my exhaust- i.e. free flow cat and muffler- at the same time, but I'm struggling with the decision between 2.25" and 2.5" for the pipe.

I've heard from at least 2 knowledgeable people that its best to go with 2.25" on this 4 cylinder motor in order to maintain proper back pressure and torque. But others say 2.5" is the way to go.

I measured the stock pipe and it appears to be 2.25", at least on my truck. So maybe I should just get the mini-header and leave it at that for now.

***EDIT*** Checked again in better light and can see that the 2.25" is just the last foot or so, where it flares out slightly. The stock pipe size appears to be 2". So I will go with 2.25" for my new system.

I would like to hear what size exhaust other 3RZ 2.7L engine owners are going with.

RE dealer pricing on this item- it is worth it to print out lower online prices and give your local dealer the chance to match it. Sometimes they won't go quite as low, but you also need to factor in shipping charges. My experience lately is that with the slow economy they are more amenable to working with you, some cash flow is better than none at all!

CDUFF7 · 11-03-2008, 06:20 AM

Anyone know if there is any problem installing this on the 4Runner 2.7L ? Seems it should be the same exact thing.....

96redtoy · 11-03-2008, 06:39 AM

They are the same thing you should not have any problems doing that

CDUFF7 · 11-03-2008, 06:52 AM

Thanks! Do you guys think this will add a little power or even a deeper exhaust note? I am almost ready to get on this since I would like to do this before a crack develops in my 3rz

I've been wondering this as well. The engines of course are identical, but some of the aftermarket 3RZ headers fit Tacomas but not 4runners- I think because of interference with a passenger side frame member.

But the stock Toyota mini-header is the same dimensions as the cast version, and apparently fits the same downpipe. So I'm guessing/hoping the mini header will fit my 4runner...I plan to buy a junkyard one unless the dealer can match $170.

96redtoy · 11-03-2008, 02:10 PM

Let me know if the dealer matches your price

TOYOTA 1 · 11-03-2008, 02:28 PM

i wish i had known about this before buying a 330 dollar header

CDUFF7 · 11-04-2008, 12:27 AM

Can't wait to see the install pics, step by step. This has got me excited!!!

96redtoy · 11-04-2008, 04:24 AM

should be here by thursday can't wait

Conatus · 11-08-2008, 06:40 PM

How does this compare to an LC engineering header? I am assuming the LC header requires further mods to ones exhaust.

96redtoy · 11-08-2008, 07:15 PM

Well got it all together today pics coming soon

does anybody know what the torque specs are on the nuts that hold the manifold to the head (there the ones that go on the studs coming out of the head, don't want to pull the studs out of the alumi head)

Found it 36flbs

CDUFF7 · 11-08-2008, 09:24 PM

I am psyched about seeing how it turned out.

96redtoy · 11-09-2008, 09:04 AM

so here it goes

well i got this in the mail

then removed all the intake stuff and got to the manifold

then I removed all the nuts which I sprayed throughout the week with penitrating oil

then I had to drop the exhaust down so the studs coming out of the manifold would clear it so I could pull it off the head

had to take out those two bolts to let the exhaust drop down

also had to take off the hanger

96redtoy · 11-09-2008, 09:14 AM

then I got it off yeah

This little sucker was pretty tough to get of but I got it

taped off the ends

painted

all together

Started right up and ran real nice.

Took about 3hours and ran into no problems what so ever. I would recommend that a week before you start this project to get some good penitrating oil on all the bolts and studs that will be removed helped out alot because everything came apart like it was built yesterday. I oiled them three times before I went at it

It feels like I might have a little better throtle responce and a little harder pull in the higher RPMS If I had an after market exhaust the rest of the way I am sure it would be much more noticible.
