You wanna trade that Thorley for my stock manifold now? Heard you were looking for one lol

Newly rebuilt 22RE, bored .020 over, compression ratio estimated at 9.46:1, engnbldr head with oversize valves, 261C Crawler cam.

Is 2.25" tubing - with the Doug Thorley header and 18" MagnaFlow muffler - the right size tubing?

Should all bends in tubing be mandrel bent?

I want my performance gain to be in the RPM range of 2500 to 3500.

I want more torque.

The gain in horse power at 5000 is less important for my driving style and need.

I think for the application mandrel bent isn't worth it. Yes, there is some crushing when it is bent the other way but it's not like you are trying to push massive horsepower out of it. The gains of mandrel bent will be very marginal.

[emsvitil]

No wrinkle bends.

A trick is to go up 1 tubing size for non-mandrel bends.

Do they have 2.375" pipes,   that would be perfect for going up a size....     


The tubing crush won't matter after the muffler,  exhaust gas has cooled and there's less volume.

Flip thr header and run it open. That should have a gain

299k... you locked your engine building thread because people were posting dilly dilly – a funny -  4 times instead of asking questions? 

You post a funny here, which I enjoy.  A good sense of humor is an admirable personality trait. 

Do I sense a little hypocrisy?

Go look at Sassparilla_kid's rebuild. The first two pages are people arguing about the 84 85 86 changeover years. Poor guy is just trying to rebuild an engine and theres half the forum clogging up his thread

I too think that for your application it won't make a noticeable difference between crush bends and mandrel, especially at the lower end of the powerband, and that 2.25" will be fine. If you put on a 4x9 oval magnaflow muffler I suggest adding a 14'' resonator to quiet it down and to mellow the tone.

Hey G,

Thank you for sharing.

I don't recall seeing that video - very interesting.  The resulting engine dyno test is pretty typical from what I've read and researched in my past.

There's a couple differences between that engine and a 100 HP 22RE.  First, carb vs EFI and secondly - WOT vs. street driven.  So I have LOTS of questions regarding a comparison.

So far, two 22RE engine builders have stated that 2.25" exhaust with the DT header is about right, and that mandrel bent tubing vs compression bent tubing will not be a noticeable factor in my exhaust system and engine.

I am concerned about the exhaust system being too loud, so I will want to have the option of retro-fitting another muffler if the 18" MagnaFlow muffler is too loud – at no extra cost.

299k...

If you start a "build" thread on a public forum and expect completely and exclusively linear replies – you are delusional.

I've said it before... the very BEST threads I've read have multiple tangential, emotional, highly debated and protracted discussions. 

That's only my experience on automotive forums since 1999... yours may be different.

maybe so, but I can go to any of your 41 pages and at least a large chunk of the page will be off topic. I don't like having a build page where the first page is half derailed with "dilly dilly" and external links about what "dilly dilly" is.

My build thread is one of THE most reviewed.... so it must not be too boring, cluttered, or derailed. 

I like the dilly dilly's in my thread!! 

In fact, I think every thread should at least a couple dilly dilly's.

I have a doug thorley header, 20/22r ported, o/s valve, stock cam and comp. I have switched from 2.5'' OD exhaust to 2" ID with no noticeable difference in any driving condition, exept for WOT below 2500 rpms which I couldn't test for carb related reasons which I fixed just before ripping the front suspension hangers off the frame in the trails.

As for EFI vs carb and exhaust tuning, I agree there are differences but it is still about harmonics. The differences will be much less noticeable on a 100 hp 22re between 2.25" vs 2.5" or mandrel vs crushed. For best results there are aways engine analyser softwares as engine pro which will calculate the best exhaust specs acording to intake manifold design, runner length, cam spec, displacement, wave tuning etc etc. I have never used such softwares but they are very popular in more advanced or competition builds.

I agree.

I have one of the best desk top dyno software apps available.. at least that's my opinion, and I will be doing some "mock" dyno pulls before driving my truck to the muffler shop... if just for poops & chuckles.

I believe that is factually inaccurate, especially considering how many pages you have.

For the love of all things bud light and Toyota we have a 42 page engine build thread on a darn 22re.

Hey G,

Thank you very much for bringing up the Engine Analyzer!! 

I just spent a couple hours plugging in some numbers and doing a bunch of mock pulls.  I think they are fairly close to what you suggested.... and a little  better than I expected.

I will need to compile the data in a comparison speadsheet and post it later.  It will take me another hour or so to do that.  I compared a factory stock 1986 22RE and added just exhaust mods.  I did the same thing with MY engine build specs.  I went from 1.75" to 2.50" with DT header and high flow muffler.... VERY interesting results. 

Of course, whether or not those dyno results have anything to do with reality is yet to be determined.

Before you put it in,  measure

1.   Primary tube diameter and length
2.   Secondary tube diameter and length
3.   Collector tube diameter and length.
4.   Merge angles


Might help for some understanding on header design....

Hey Ed,

I have not forgotten about your request. I have to buy a cloth tape measure today.
