OEM mini header install for 2.7L*(Pics)* - Page 4

I know right..Im not very picky about looks, And I think the headers would look OK sans the shield, but the shield makes everything look complete and normal.

Thanks for the kit again Josh, You da man !!!

Try looking HERE; search for Tacomas 01-04.

Not very many 4runners came with the mini-headers, although it seems a few did. My understanding is that the mini-header was a mid-year model change in 2000-2001. 2000 was the last year that 4runners were available with the 3RZ and the vast majority sold came with the V6. So unless you find a 3RZ 4runner from near the end of the 2000 production run, they will probably have the older style cast manifold.

EDIT:Mini headers came on all 2000 California 3rz's and 2001-2004 3rz's both Cali and Fed. So it is likely that only California 3RZ 4runners have the mini-header stock.

Anybody have the torque specs for the STUDS? Tired of looking for them.

**DeathCougar** · 06-07-2009, 12:27 PM

which studs, on the manifold or the pipe?

dport · 06-07-2009, 03:14 PM

for the studs themselves, going into the head

This is the closest I think you will get

Thanks a lot. I ended up just cinching em down a bit, and torqueing the nuts to 36 ft lbs. It's all together now and running great. I'll have to load a pic of my busted manifold later.

gornish_hick · 06-10-2009, 08:01 PM

looks good man.

is the manifold crackin like that a common problem with the 2.7?

**DeathCougar** · 06-10-2009, 09:58 PM

Very very common. In fact, I have found that its not a "will it happen" issue, its a WHEN will it happen issue.

dport · 06-11-2009, 10:18 AM

Mine lacked about 1 1/4 inch before becoming two pieces with only 148K on the truck.

Sorry for bumping an old thread and asking a question that might have been asked before. But I think it might help others in the same situation as myself.

I have a 98 4Runner with the 3RZ. I am looking to do the OEM mini-header install as a precaution. I have found a manifold off a 2003 Tacoma with a 2.4L motor. I am pretty sure that the manifolds are interchangeable between the 2RZ and 3RZ. I was hoping that one of the experts can kindly confirm if this is in fact true. Should I be concerned with the flange size (3.75" vs the 4.25")?

Thank you very much.

Manifolds have different part numbers according to Toyota. Not really sure why.

tonythebullet · 07-03-2009, 09:57 AM

I think the part numbers are different because the heat shield mounting bolt locations are different on the cast iron vs tubular manifolds. Both manifolds use the same gasket to mount to the block so there shouldn’t be any problems in that aspect. I mostly have doubts over the downpipe flange - the part numbers for that particular gasket are different. Its taken me 2 months of rigorous hunting to get a great deal on the manifold locally so hopefully I won't have to pass up on it.

I replaced mine with LCE headers when I bought it. It had a giant crack. I ripped it in two just for giggles with my bare hands (have the video, if anyones interested ill put it on youtube).
