EDIT: Scroll down to the 2nd post, i have a ton of videos there of the truck over time including some burnouts and street pulls!

Howdy, long time no see ya'll.

I am sure a few of you remember me, i still see a few familiar faces floating around here. Been some time since i have really posted on here since i have been busy working on my MR2 the last few years.

Well i blew the old motor in the MR2 up a few months ago and while i am waiting on the new one i decided to catch back up on the 4runner and do some mods to it that i have been wanting to do for a long time.

As a refresher on who i am since i am sure 99% of you don't have a clue who this guy with way too many posts suddenly posting is. I have the 2000 Limited 4runner 4WD that I supercharged a few years back with a 1st gen supercharger on a budget.

Here is my old build thread from 2 years ago: https://www.yotatech.com/forums/f200...begins-146485/

http://www.youtube.com/watch?v=hvGSvHTPX3M

Mod list from that point in time was

TRD 1st gen supercharger
URD 7th injector kit
Doug Thorley headers
Gauges and tuning tools

On the stock pulley making about 5psi of boost this is what i dynoed just after getting it running:

Not too bad seeing as i had some issues that day as well.


So thats the back story, so now for a long term update. Been driving it for 2 years now, i have beat the living heck out of it during that time. including but not limited to towing MANY cars some upwards of 200 miles and weighing 5000lb+. Plus i drive all my cars like i stole them. It has held up GREAT, not a single issue in this time at all.

Just normal oil changes. My Gas mileage has even been pretty good, on the highway i have seen as much as 21-22mpg. Power has been great as well, i am VERY glad i did this even though i now have MUCH faster cars (that MR2 above should crack 500rwhp+ in the coming weeks). The extra power is so nice just normal around town driving, makes the truck so much more fun to drive. I do not regret for 1 second supercharging my 4unner, one of the best things i ever did.

Here are some pictures of how it stands now:








Here it is doing some mall crawling, sorry no pictures of it off-road, although i have the messed up front end alignment to prove it has been there.



So thats up to the current as of last week. Now for the mods i have done in the last few days.

Biggest thing i did was install an AEM water/Methanol injection kit that was donated by the MR2 (it is moving on to bigger and badder things). I am making a video that will go into great detail about the install and setup but here is a quick rundown.

Installed it using the factory washer fluid reservoir and in a fairly "sleeper" setup. I am using a 7gpm or 450cc nozzle, this is a little bigger then they recommend for a 3.4l motor but it is what I had on the MR2 so i used it (well actually it had 1 450cc nozzle and a 900cc nozzle for a total of almost 1400cc but thats another subject, although i would be happy to go into it if ya'll want).

I played around with different mixtures of water/meth and settled on a 50/50 mixture (vs the 100% pure meth i was using in the MR2). On the stock pulley i noticed some gains for sure, my boost also went up by about 1psi. After some tuning the power gains were VERY noticeable. I was able to zero out my timing map on the URD with no signs of knock.

I then installed a URD 2.2 pulley i have had in the garage for 2 years, it upped the boost by another 1-1.5psi and at this point the power gains were VERY noticeable. It is a whole new truck! Butt dyno says ~250rwhp.

The rest of the details i will explain in the video i am working on, should have it ready in a few days.

Here are some pictures of the meth install:





Here is how i tapped it into the stock washer fluid tank:

And here is the status light mounted next to my wideband, this will let me know when it is spraying, if it is low on fluid and if there are any shorts:



Smaller URD pulley:



Fuse block i am VERY proud of, installed this a year ago or so, $5 each from pepboys and makes any wiring on the truck SO much easier and better.



I have done a LOT of work and playing around with water/meth injection so if ya'll have any questions about it feel free to ask! I will do my best to help you out. Get me interested enough in 4runenrs again and i might stick around lol, i have been bit by the speed bug so thats where most of my spare time is spent latly, trying ot go faster.

First off here is the first video most of you have seen of the first start:

Next is the dyno i did a few weeks after getting it running with the stock pulley making 222rwhp:

http://www.youtube.com/watch?v=SKQ7mjjeoCg

Here is when I took it to the 1/8th mile drag track and ran it with a few hundred pounds of MR2 stuff in the back, still on the stock pulley and still managed to beat a miata:

wow...long time no see...that truck is amazing...

Texas_Ace

Thanks! Good to see somone remembers me, i have been lurking from time to time just don't post much since i am always working on the MR2.

Did you rate/comment on the video? lol

The truck is very fun to drive now, i really like it since the smaller pulley and water/meth injection as well.

camo31_10.50

i'm too lazy at the moment to rate and comment the video

i remember you though for sure!

that burnout in your above video made me want a SC'd 3.4....lmao i think i'll stick with a turbo diesel though

well... looks like i'm looking for the 2.2 pulley..

Good Job brother--i remember you--

Texas_Ace

Just as long as you remember later, 1 click and the comment can just be cool for all i care! lol

What do you know, guess i am not as forgotten on here as i thought.

The Diesel is also a good choice, i really thought about that myself, for a truck that spends more time off-road then mine that might be the better choice actually.

THANKS!

Interesting tidbit about that, i actually installed this pulley when i first got the SC installed. it gave a little more power but not THAT much due to me having to pull out some timing with it to be safe.

On the dyno going from the 2.2 to the stock pulley only lost me 5hp once the truck was heat soaked which is why i left the stock one on there.

On the other hand with the water/meth injection in place as well, the gains are VERY noticeable and are not effected by heat soak.

2.2 pulley = good, water/meth injection = good

water/meth injection + 2.2 pulley = REALLY good

I am really thinking about going with a 2.1 pulley actually.

I can also show anyone that is interested how to build a water/meth injection setup for $100-$150 if ya'll are interested. even a small amount of washer fluid from a setup like mine would help power a lot even if you didn't tune for it.

Good to feel loved! Commented?

Do a write up for it and submit it. Could help someone * cough* me.... Later down the. Road

I will do that, i have a video i am editing now that goes into quite a bit of details about my setup. Once i get that finished i will put together somthing for a cheap meth kit setup.

GREAT! Thanks! That jeep guy was saying he hit the 304 hits mark, so youtube won't updated his hits but every few days now. He is ahead i know that for sure.

YES!!, finally someone else using water/meth injection!!! with proper tuning of the ignition maps and the injection, you can make MUCH more power than you 7th injector weirdos hahaha... well, not necessarily so but ya know....

nice setup using the washer tank, you can actually still use it for cleaning the windshield too if you stay with a 50/50 mix, that's pretty much washer fluid minus the color anyway... (a bit stronger though).

your nozzle is mounted almost dead on where mine is, I think mine is about 1.5" closer to the TB but pretty close.

voted on your vid also, nice burnout btw...

how much boost are you making with the 2.2" pulley? I'm only at 8.2psi max, which is a tad low but curious to see what your final pressures were.

thanks, sweet runner too man.

iTrader: (1)

oh yeah, go with either a 4 or 5gph nozzle, that 7 is way too big for this setup. even my 5gph is probably a bit much, it does suck methanol but a 4 is about dead on. if you go to alcohol-injection.com they have a nozzle calculator on there, for a 3.4 4stroke running 8psi it comes out to about 4. something.

Texas_Ace

Yep, water/meth injection is truly remarkable. On my MR2 i saw gains of 20hp JUST by turning it on, no tuning past getting the AFR's back to the same point (was injecting almost 1500cc so that was a must), no extra boost, just the meth.

Once tuned i ended up with almost 30rwhp in gains at the same boost.

Here is a dyno comparison, ignore the dip on the meth pull, i was still tuning it and it had a rich spot:



That was at 14psi of boost for both pulls.

Goes to show how effective it is. You could easily get a proper methanol setup instead of a URD 7th and it would work perfectly fine. You would need a good kit though, i recomend the Aquamist HFS series.

Yep, it still works on the windshield as well. I have the nozle there because i didn't trust it in the rubber, i was going to mount it under the piping to make it truly sleeper but just no place to do it. On a SC setup doesn't really matter where the nozzle is long as it is before the TB.

I am making 7-8psi on the 2.2 depending on how hot it is outside. my roots are a little worn though so thats about 1psi of the drop, the headers are the other 1psi.

Texas_Ace

Actually it is working great, i did a LOT of experimenting with nozzle size on my MR2 (ended up using about 1500cc on a 2.0l turbo motor) and found that more meth was better, the only limiting factor is how much water you can inject, long as you can tune for it can injecto almost as much meth as you want.

In the case of my URD piggyback a 50/50 mixture is right within it's tuning abilitys. If i could not tune it, i would run a smaller nozzle.

Now if i had a nicer setup like an aquamist, i would run a large nozzle since it actually allows you to tune the meth injection.

For the last year i have don't almost nothign but play with meth injection lol. In fact you could say my MR2 is having the ulitamate meth injection setup built for it. Gonna be injecting over 8000cc of meth, litterally like putting a water hose down the intake full blast.

nice, thanks for posting that dyno graph too. There are so many kits available, some inexpensive, I don't understand why more people aren't running injection.

I put my first kit on my taco prior to anything else and saw incredible power gains and started getting 50+ miles extra on a tank of gas. It has all advantages and literally no disadvantages minus the initial set up cost.

glad you are able to use the larger nozzle, you're the first one I've seen running that much. I have a couple of 7gph's sitting around, maybe one day when I get bored... hmmmm.....

Yeah, I hear ya on the crappy rubber intake (as far as nozzle mounting is concerned), I used an outside mount nozzle at first but worried it would pop off (100% meth on a hot manifold seems like a catastrophic problem). I switched to an inside mount with a star washer so it wouldn't pull out which worked great and still use an inside mount on my new chrome intake tube.

whenever I get my old laptop replaced (fried motherboard) I will retune my timing map with the meth and will get it dyno'ed. I will try and remember this thread and post it up

thanks!

Texas_Ace

Meth injection is just not understood by enough people. thats actually why i have done so much playing around with it, i wanted to see what was REALLY up with it.

I have found it is truly amazing stuff with no downsides other then like you said, setup cost. Even a small 100cc nozzle with pure water/washer fluid that needs no tuning will give you gains (more so in a hot climate like mine).

Nozzle izing is also one of those myths that i have blown away, i mean just look at my MR2, they wanted me to use a 2 or 3gpm nozzle on it and said i could not run anything bigger then a 7. Well i used a 7, then i used two 7's then i used one 7 and one 14 for a total of over 21gpm, take into account the high pressure i was injecting it at, i had about 1500cc of meth being injected.

I did that just to prove it could be done and the gains i saw from it, well speak for themselves.

The sizing calculators you find online are good if you can not or will not be changing the tune. If you have the ability to tune it, then more is better up to the limits of your tuning abilitys. Meth is a fuel so you can inject a ton of it, water is the limiting factor and you can always just run a meth biased mix to counter that.

I found pure meth works better at the extreme anyways. I could go on forever on water/meth injection lol.

Only problem i have with my nozzle is that the ISR is actually filling up with water slowly lol, i plan to remove it anyways so no big deal won't hurt anything.

I am going ot make a writeup later on how to build a meth injection system for around $100 - $150, for that price there is NO reason ot not run one. As you can see, an install like mine doesn't get in the way, is easy to install and works very well. Another advantage of using the factory washer tank is you don't have to find a place for a resivor somplace else. It also holds a lot of fluid, about 1.5 gallons from my calculations.

yes, really the only major cost is a pump and the controller. everything else is cheap/easy to come by. (nozzles I get cost about $5-9 depending on what type) My kit has a shurflo pump in it, not sure what the other kits are using. Devil's own has progressive controllers, right now I'm running off my MAF sensor with decent results but most folks from what I read have slightly better performance with a MAP/boost controlled system.

I know a few folks with souped up cars and all of them run 100% meth, I did sometimes also just for fun and like you said, with a small nozzle, there is no absolute need to tune it while still getting more power. I will be playing around some more with the bigger nozzles to see what I can get!!

Texas_Ace

A fancy controller is nice and all but a basic setup with an on/off pressure switch works perfectly fine for 90% of cars and it a LOT better then nothing.

You just have to size the nozle a lot better if you don't have a progressive controller or you will bog down low.

As i said, i am putting together a list that will get you running a small nozzle for about $100, even on an NA motor i have seen 10hp gains from a setup like this just for the lower intake temps (obiously more noticable in hotter areas)

Shurflow pumps are great, 90% of kits now days use them.

I have some long writeups on what i think about meth injection on other sites but a basic rundown is there are 3 basic setups:

Cheap DIY setup, $100-$150. Works, simple but limited on the nozzle size you can run.

Basic progressive kit (forget the non-progressive kits, make a DIY kit if you want that) from a big name, $200 - $400 this will allow you to run a larger nozzle but will need some kind of tuning to get the most out of it

Top of the line kit, Aquamist HFS series $500 - $900. This is self tuning and could be used in place of a 7th injector kit. Can use a really big nozzle and will see the most gains from this.

Any will work, just a matter of what you want and what you are lookign for. if you just want an added safty margin and won't be pushing the setup, go DIY.

If you want to run a 2.0 pulley, no URD kit and want to make big power, go Aquamist.

I am loving this setup on my truck, as the ECU selfadjusts for it more and more it is getting even better. Also, no more power loss from heat soak! used to get noticable power loss after a little dirving, no more!
