Greetings,
So, I blew the engine in my 22Rlast week, loud Ka-blam, and mixed it’s oil and water. Pretty sure it’s a dead block now. Luckily I got a little cash set aside to pick up a rebuilt engine. I’d normally rebuild, or build one up, but it’s my daily driver, so I need it up-n-running ASAP. I’m pretty good with mechanics (30 year hobby) , but a little new to Toyota 22R engines. I’ve learned a bit though.
I live in West Washington State,and have narrowed my choice down to two engines from two different shops. Both shops were friendly and willing to answer basic questions. Both shops are quoting me prices without the core refund since my core is shot. My truck also has a 4” lift, 31” tires, Webber carburetor, 4-1 long header and is set up as a HAM radio rig (HF, UHF, VHF, 6 Meter and CB). It is my daily driver with a 50 mile round trip 5 days a week to/from work. The truck wont see lots of off road, but it’s my bug-out vehicle, so it’s expected to be fully off road capable. Longevity is more important than performance, but a little performance is nice if it retains its reliability and longevity as well. Thus I come to you all for some food for thought regardingmy selection.
So, here are my choices:

1) Stock 22R: $1317 after core and tax.

· Shop has little info on their website about howtheir engines are built, but they come with a 18 month/18,000 mile warranty even with my own install.
· Will give me a partial core refund of $75 if the head is good, and I bring it back.



2) 22R with 260 cam and springs: $1597 after core and tax.

· Shop has a 10 minute video that shows how their engines are rebuilt, and comes with a 12 month/12,000 mile warranty even with my own install.

Both shops will ship it to my house for free, and both shops seemed willing to answer my questions.

- Hopefully you all will have some food for though regarding the choices that lay before me.

- Last, how aggressive is 260 Cam? Will it be fine for a daily driver with life expectancy on-par/simular to a stock engine? Or will longevity and reliability suffer? – The truck DOES need to be reliable, and I don’t want to rebuild it again in a couple years… But if the 260 cam is mild, and will run fine for years with about the same time as any other good 22R, then the extra power would be a welcome addition.

Thank you all in advance for your words of wisdom, or even simple personal opinion.

Kindly,


Bat.

Thank you for the links Josh, I appreciate the info. I did however find those already on a basic search for threads on the topic. Also it seems that most threads I am finding are post `84 engines with fuel injection and ECU considerations, and that plays a major role in how the vehicle reactsto, and acts with the cam, as well as longevity due to tuning issues. I guess I’mlooking for some very specific `81-`84( with carburetor) related answers. With an 82, I am not as worried about ECU issues, injectors or sensors… for me it’s spring weights, carb and vacuum J

I did find some retail descriptions of the cams, and it seems as though the 260 cam is considered as one step up from stock, and can be used with stock valve springs. It’s commonly describes as having power in the 1200 – 3800ish rpm range, with improved low and mid range power. I had hoped to hear from someone with a `81-`84 truck that could give me some feedback on how thecam has treated them, and if they had any tuning issues, or if made much of a difference the power delivery – did they like it not? and why.

After reading on the retail descriptions, and the links,online etc, I am leaning toward the 260-cammed engine. In theory, it seems that it should last as long as an OEM, since the 260 cam has only a slight increasein profile over stock. If anyone has wisdom to dispute this, or has account that shows otherwise, I would like to hear the how’s and whys…. A good technical discussion is always welcome.


Note for correction: the "87 22R Which cam???" thread is helpful - TY - adresses Carbed engine mostly. Yay.

The 260 cam is a small cam, I wouldn't worry about legtivity or reliability with it. However the carb my need a bit of a retune if it runs too lean because of the increased air flow. I have not ran that cam or that carb yet though so it isn't personal experience, just info I have gathered with my searches over time.

My experience;

1976 2wd, I rebuilt my 20R (assembly only, I'm not a machinist), 270 cam, stock everything else except 32/36 Weber. Ran like a champ and just sold it. Needed the jets sized up quite a bit over stock. Still got near 30mpg with it and it went much better than a stocker.

My current rig is an '82. I just put a 20R head on it with some mild work, LCE street performer cam and a Weber 38/38. It's a beast vs the 2wd, and that's saying something since it's 500 or more pounds heavier.

A 260 cam is so mild you might notice a 50rpm bump in your idle speed and that's about it. Should idle/behave very close to stock while giving you a mild boost in the low and mid range. I am not familiar with factory 22R carbs, so whether or not it will be equipped to handle it I can't say. 20R carbs are garbage, but the 22R had a better carb so far as I'm led to believe.

If you're going with the time old 32/36 or a bigger Weber, you'll be doing some jetting. Down-jetting on a 38 series, up-jetting on a 32/36. It's easy. Weber has very simple instructions to walk you through the process.

A word of caution on the 32/36; it will puss out on 22R's or bigger with much as far as performance mods. I think a stock motor with a 260 cam would be getting close to a 32/36's upper limits. I tried running my 22R on the little 32/36 and it just couldn't deliver enough fuel. The 32/36 is just enough carb for a mostly stock 22R, and a 260 cam isn't much over stock so with some up-jetting I bet it would work fine in your application.

If down the road you're looking at other mods you might want to stick with a bigger carb.

Just my .02. I live in the Seattle area as well. PM me if you need carb help.

You need to find out what parts their using internally and how much there boring out. That will tell you about the longevity thing...

Thanks guys for the good replies. Well, the guys with the 260 cammed engine are using ITM parts, and the stock built engine is all NPR/Nippon parts. Also, the guy with the 260 engine went awry and gave me a wildly higher price when I called back on the day I was going to go pick it up, went up to $1800 from $1500, and then said they dont ship. He gave me a song and dance about how his employee though I had a later 22RE, and the early ones are just that much more sought after… Called the guy with the stock engine, and his quote was the same as before, for an early engine …… so…. I went and got the stock engine with NPR/Nippon parts. Bought it yesterday, and It'll be delivered to my house for free, should be here pretty soon… that’s a heck of a lot better than 1800 without delivery just to have a 260 cam that’s only going to make a slight difference in torque. For that kinda price difference, I’ll run the engine until it’s out of warranty, then build a 20R head with a mild cam and drop it in at a later date. Ultimatly, I just need my truck back


So – another question if I may…

I see a lot of clutches and various year ranges – they don’t all follow the same year/descriptions leading to a little confusion on the interchange. I seen a Luk Gold part number 16-902, but it says it’s for 84-88. It was my understanding that all 81-88 22R clutches were the same? Or am I wrong here. The Luk Gold clutch has good reputation for being a step up from stock, and reliable, and a bit less than the Marlin, but I’d like to make sure it’ll fit… And Flywheel interchange is 81-95? or 81-88?
~ Your thoughts gentlemen?

Thanks again for the help.
