Wow, thats REAL pretty. No oil needed and washable right?

Correct. According to the website, 4 yr lifespan. Probably 3 for me, with all the dirt driven. But, still saves some money in the long run and should work really well.

I am running Mobil 1 full synthetic in this thing once I get to that point. Giving her every opportunity (besides supercharger and such) to really go.

Elvota · 12-06-2007, 05:33 PM

Got a few more things today. Was able to sneak in the headers. In some ways, they were easy to fit than on the 3.0... in others, much harder. So difficult to access the bolts.

Anyway, I checked the fit and then welded some 3 bolt flanges onto the end... and painted 'em black with some high temp paint because I don't care for chrome:

Then I started to work on the rest of the exhaust. Only have one 180 degree mandrel bent piece of tube from Summit to make this work. Better than before, when I just had to miter cut and weld to get things to work:

Old stuff... that served it's purpose well:

Parts for the new routing:

I'll re-use my cat and muffler. Plan to make my own sensor mounts for O2's. Got the clutch line in, slave installed and bled. Maybe a few other loose ends tied up that I can't remember.

Back at it tomorrow... weather permitting.

Did you run it yet? Looks like you are close.

breknraj · 12-06-2007, 06:00 PM

Great progress, Steve!

I'll bet that you're just about twitching to start it up!

Looking forward to hearing what you think, once you're running, again!

Very close. This weekend is the goal.

I have to finish exhaust, wire O2's, hook up the battery and a few other underhood connections, rear coolant lines, shift levers back on... I'll just keep plugging away.

I am anxious for sure. This will be a major project for me, so if she fires I'll be extremely stoked.

Once over that hurdle, I can't imagine I'll be depressed with the new found extra HP and torque.

Elvota · 12-06-2007, 10:31 PM

Does anyone have any detail pics or can let me know which coolant line from the back of the 3.4 goes to which coolant line coming from the firewall on my '90?

I have 2 to hook up, and can't seem to find a coolant flow diagram online for the 3.4.

Thanks in advance.

fillsrunner4 · 12-06-2007, 11:02 PM

the driver side coming from motor goes to the swich controling heat level entering heater core and the pass side coming from firewall goes to pass side going into block.

fillsrunner4 · 12-06-2007, 11:06 PM

Good thing you can use your stock y pipe to conect the both i had to use a magnaflow to join my downeys together since i tossed the original. that 180degree bend should work great to make it work.

Looking good

Sweet. Thanks for the info. I may be tackling those lines as soon as tomorrow.

You lost me a bit on this one. I will be cutting that 180 bend into multiple, shorter bends and then do my best to make them all blend together. Before, I just got bends from the local Autozone. This time, I'll try and use this piece of mandrel bent to streamline the flow and get a better finished product. I'll be making my own "Y" pipe to tie the headers together. That will run under the tranny but above the front DS. Worked well on my 3.0 and kept everything tucked up out of harms way. The dual cases give me a fair amount of room to work with.

At least... that's the plan.

fillsrunner4 · 12-06-2007, 11:27 PM

Haha i thought you were going to use the old exhaust to blend into aka tying into the old ypipe. What size pipe are you using? if the old is 2 1/4 and the new is 2 1/2 then i can see making your own ypipe but you could use the old ypipe it may be easier than making your own just IMO and if your using the stock diameter tubing.

I ran the downeys that same way and they should work and fit great. I flat bellied mine so the hardest part of mine was fitting it above my crossmember huge PITA but it worked.

Yes the duals definetly help with space lol

Elvota · 12-06-2007, 11:32 PM

Since the Downey headers terminate at 2.5", I'll be running 2.5" back from them to the cat, muffler and out the end.

That's what I had on the 3.0 before, so hopefully it will work well for this application also.

fillsrunner4 · 12-06-2007, 11:37 PM

They actualy advise not using any bigger than that and if at some point you supercharge or anything that would be optimal

as for wheeling the smaller would give you a bit better with the low end torque however since you have duals youll be plenty set

I would recomend the 2.5 as well. What kind of muffler do you have? Looks like a magnaflow

Elvota · 12-06-2007, 11:41 PM

It's just a Summit Turbo muffler. I did have a Magnaflow a while back with the 3.0, but it was really loud.

Actually, the tone was probably all right... it just sucked having my 4Runner sounding like a V8 and pulling like a 3.slow.

I know what you mean haha. I liked the sound from my flowmaster so i stayed with that for now. My buddy had a magnaflow on his 3.0 pickup and when he sold it the guy said it sounded like a v8 and he was sold. thats funny that you said that.

Wont have to worry about not pulling its wait after the swap thats for sure

Elvota · 12-07-2007, 04:00 PM

Rainy afternoon here today, but luckily got a fair amount done before hand.

Really glad I got that mandrel loop from Summit. Worked out very well, vast improvement over my 3.0 Y pipe.

The 3.0 headers went further back along the frame, causing me to run out of room and create this horrific "bend" off of the PS header. It did work, and cleared the DS. Before, when I had a local muffler shop do the job, they didn't cross over until behind the single transfer case, which put the cat at the rear axle. Believe it or not, my way was an improvement... at least to me.:

I had always planned it to be temporary until I got the 3.4. At least, I had always hoped to swap in a 3.4. Now, the much improved mandrel bent version:

The combination of the 3.4 headers being slightly shorter, my addition of the dual tranny and just a general improvement in my fabrication skills this Y pipe really came out well, IMO.

No closeups of the welds though, I still lack in that department, but getting better. They seem to hold up, so I guess that's the important part.

Nice and tight but no touching:

Was able to get it tucked up there pretty good. Should be mostly out of harms way on the trails. :

The rain then started to cramp my style. I was able to make space in the garage and plan to push it under cover to finish. Pretty much just have some wiring connections and coolant lines under the hood to figure out. If I get lucky with some off the shelf hose bends from Autozone, I should be in fairly good shape.

Who knows... may even be able to turn the key tomorrow afternoon.

fillsrunner4 · 12-07-2007, 04:05 PM

Hell ya that y pipe looks way better. You should post the shop who did it before because that is rediculous.

You should think about adding a truss to the upper part of your front axle since that motor weighs a bit more. Plus they look sick and make the axle muh stonger

Prepare for rant....

I'll try to not go to go to far off topic, but it was the Midas right near me. Spelled M I D A S. I figured a national chain, "muffler experts" and close enough to the house so I could drive there with my freshly installed open Downey headers at 7:30 in the morning. Plus they have all the experience, tubing benders, welding equipment, lifts... yada yada yada.

I have never been so wrong.

Their overall "design"... for lack of a better word. I told them I wanted it tight to the frame for running trails. I don't have a pic, but it was way lower than my frame rails when they where finished.:

Super rad tailpipe. I think the bling tip was a gimme. Sweeeeeeeeeeet.

Some of the welds.:

The Midas version of reusing the O2 sensor bung. Why would someone go to all the trouble to install headers and run 2.5" back just to have it bottleneck like this...?

You can see all the exhaust leaks. I only ran it for three weeks and then cut it all out to redo it myself. There was maybe 3 or 4 more sections welded that poorly.

When I took all the parts back up to the shop to complain and get a refund, they told me that was a no go because they didn't have a chance to fix the leaks. Thing is, you couldn't see the leaks until the system was cut out to look at the tops. Their explanation was... ."it's hard to fully weld the pipes on the vehicle". MIDAS SUCKS... at least this one does.

Should have gone to a little guy, a guy who cares... but didn't have the ability to drive the 4Runner very far without exhaust and didn't wish to incur the extra expense of towing it somewhere. In retrospect, that was a costly mistake. Live and learn.

So... that's why I do all my own exhaust at this point. I figure even if my welds aren't the best and I have a few 'odd" curves, I am still in pretty good shape.

Hmmm... after my rant I started thinking... maybe you were referring to the harsh "bend" at my 3.0 PS pipe being "rediculous". If so, you are still right, but that was me who did that.

lol sorry but that is pretty funny. Thats ok your new system looks much better

That shop needs to fire the idiot who welded that. My first welds ever was building an exhaust for my chevy 1500 and they dominated compared to those Midas welds. Ive had problems with them aswell but nothing like that

Elvota · 12-07-2007, 06:46 PM

Yes... does seem I missed the original critique. But feels good to get that whole Midas thing off my chest.

And how dare anyone say my work is "rediculous".
