more HP for 86 EFI

[roderunner]

Have an '86 EFI 22R-E with 250K miles that works fine. Have kept it up since new and want to get more HP so I can haul my little travel trailer faster. It has the heavy duty package/ 5 speed manual with A/C and power steering assist. Can I add turbo or increase cubic inches, or what? to increase power?

 

[dorton]

Sure. How much horsepower do you want to spend $$$?

Engnbldr has complete, and bare heads available with oversized valves, and also different cam shafts. LC Engineering has bolt on performance kits, turbo kits, and superchargers. They also have stroker kits, and stroker complete engines. It gets expensive hp per dollar pretty quickly. How much do you want to spend? Are you mechanically inclined?

I would stick to the normal bolts ons. Intake headers exhaust should help out a lot.

This comes up a lot. A google search will give you lots of options, but if you're looking for more pep towing and climbing, going from up a ratio or two from your stock gears will help a lot. I have a cam and header on my 22RE, but the biggest thing that gives my truck pep is probably the gears (5.29 with 33" tires).

Dollars to spend not set yet

Thanks to you all-I will check out these many options to see what's best.
I do have the tools and know how for most work, but don't want to get too complicated, and no 33" tires for me.:hello:

Pulling Camper

I also pull a small camper with an '86 22re:




I did several mods to make this manageable. First I did a complete rebuild, which I needed because it had 300k and was burning a lot of oil. Doesn't sound like you "need" this, but if you're going to tear it down, it's not that hard or expensive.

Bored 20 over at the machine shop.

Put on custom head with larger valves, bought from engnbldr. Used his 268 RV cam also.

Added LCE down tube headers.

All of this seemed to help quite a bit, but I really only noticed a huge jump when I also did the "82 supra AFM" mod. I don't think that mod made all the difference, but I think it allowed the other ones to really do their thing.

I can tow this little camper 70mph with no issues at around 18 mpg.

Without the camper I'm getting 25mpg. Before this rebuild I was only getting around 19 and had nowhere near this much power.

This is awesome. I've got the engnbldr head on my list, but I was planning on skipping the Supra AFM. Are you running the stock airbox or a cone filter?

 

[txclimber]

It's a small cone filter.

Re-gearing is great and will indeed give you these power upgrades, but nothing's free. You gain these at the expense of your hwy speeds and gas milage. No problem if it's your wheelin' rig, but if it is your daily driver, you will grow tired of high rpm highway driving. Essentially, it's like giving up your 5th gear in favor of more torque. Ride around at 75 mph in 4th gear for a while. If you're ok with that----re-gear.

Good points. At 80 mph I'm at around 3500 rpm. The motor doesn't mind that RPM, but it is loud. On the flip side, I climb mountain passes like a goat on 'roids and don't bog down in headwinds like I used to, so it's a tradeoff I'm content with.

Regearing doesn't seme to affect rpm's as much as i thought it would. My gauges also read 3500rpm @ 80mph. Been through a zillion "how fast you're going" things at different speeds, they've all indicated that my speedo is spot on.

All I know is I went from 3000rpm at 70mph on 31's and 4.10s, to 3000rpm at 68ish on 35's and 4.88's. But it now "feels" like the gears are closer-ratio than stock.

As has been said, because the 22re is a cross draft motor, the more you can let lt breath the better it will run. my 84 has a 22r bored .40 over, with 1mm oversized valves both intake and exhaust, Tri-Y header with 2.25" exhaust with a weber 32/36 DGV and It pulls great. These are great little motors and can preform well. Do lots of reading there is a huge base of knowledge out there. and by the way there is a supercharger that is available for this as well.

TXclimber-What you've done sound really good, were the mods mostly ready to bolt on? Did you have to do anything to the gear box or differential? I'm not burning much oil but am getting closer to rebuild-if I can find a reliable machine shop in Albuquerque, as I've done most of the work myself but when I take it in to get something done I end up losing small parts that no one knows how?

 

[txclimber]

Everything was bolt on and pretty easy. If you decide to get after it, PM me with any questions and I'll help the best I can.

When you take your block in to the machine shop, there are no little pieces. It's totally stripped down, so there's nothing they can loose.

If you do the 82 Supra AFM it's mostly plug and play, but you will have to fashion up some bracket or other way of holding it in place. I used the supra's bracket and bent the hell out of it until it lined up where I wanted it. Then a couple of zip ties and called it good. I'm sure there's a prettier way, but I've never been a "fashion over function" guy.

Txclimber, what size tires are you running?
