i have a 87 4runner 22re going to instal doug thorley tri-y headers on it, i was wonder what kind of cam shaft would best fit the headers.

 

268 engnbldr cam works real well for my set up , that said more info on your motor would be a big help so you don't get over/under cammed

 

anything in the upper 260's will be a benfit with a header. Dont have to neccasarily go with engnbldr. You can get your own cam milled at a local camshop plus other sources. I have a 260 cam on a 22R I got thru Delta Cam in Tacoma, WA for a VERY awesome price, bring em your stock cam, walk out with whatever cam timing you want. Great place!

Honestly tho, overall performance increase isn't amazing so dont expect a mircale with whatever cam timing you go with. It's still a normally aspirated 22R(E) but expect a marginal performance increase.

 

my engine is going on 200000 miles, i'm in the process of rebuilding the engine now and is gpoing to remain mostly stock. i also have a k&n cone filter, high flow cat, flowmaster 40, and 2 1/4 exhaust pipe to install.

thanks that sounds like the way i'm gonna go, bring it to a shop. i'm a aware of the little perfomance up grade but i heard all the parts to gether u can notice something. A little something is better than nothing

 

Hey Frisco,

Ted, from Engine Builder, did a great right up on 4x4wire, I believe, on exhaust. He said 2" all the way to muffler then 2.25" after the muffler.

Are you in Cali, Frisco? If so, which 'high flow cat' did you get? Everyone I've tried to get is like 8MILLION DOLLARS! lol. Jk, but it's HIGH

 

Do you have a link?

 

Hey Dove ,

I think I do, but I'm on my laptop outside, workin on my rig, "ChefYota4x4's '87 4Runner Build up" thread. I'm doing the LCE 4-1 Y-type to CAT, 2" on to Muffler(haven't figured out which Muffler), and then 2.25" out the back.

Here is Ted's email to me, ....

"There is lots more gains in exhaust system improvements, a 2" pipe size into the muffler with 2 1/4" on exit creates directional flow and puts around 6-10 ponies to the ground.

The 261C is OK for hills, and good if you get offroad a lot. The 268C is the best choice by far for highway and towing/hauling or dealing with hills.

For wires, we use OEM, you can't find better.
Ted"

 

Hope that helps, GOOD ON YA!

PS> My homie is in Eugene.....HATES IT, lol. Nah, he loves it, but he misses the Cali Sun....he's always whining to me about that rain up there! lol. BEAUTIFUL though!

 

It's been too cold up here lately! I'm ready for a 70 degree day. It is May after all!

I have to do something with the exhaust on my 85. Muffler has holes it it. I have no idea about the cat. It looks like the original. Doesn't Ted recommend against headers, just because they don't realize that much hp gain?

 

I'm in sf bay area and I have a high flow cat, and it passed smog lol I'll dig through the reciept to see what brand it is. I wanna say magnaflow becuase thr muffler is a magnaflow and both were installed at the same time

 

THANK YOU GUYS FOR ALL THE HELP!


to drew,
how would i go about asking a shop to machine my cam shaft to get 268 out of it.



chefyota,
i can't remember the kind of cat it is. but i did pay an arm and a leg for it , i think they even took one of my big toes

 

great information
