peter, christian, thank you for your help..Come to find out the 7th injector does not work w/ my 98. so it looks like the URD fuel upgrade kit is the way to go! Im gonna go with 2.2 " pullleys as well .Ill be in touch w/ the updates

i have a K&N cold air deal(before i discovered yotatech)
1.does this all go away? do i need to reuse my stock stuff
2. if this doesnt go away, does Amsoil make the cone i can replace the existing with?

 

Kenny, you might keep your eyes open on ebay because every now and then someone pulls their system off and has it for sale (including the URD kit). I saw one go just last week (I think it went for about $1770 total, S/C and fuel mods).

Just a thought anyway.

 

I was wondering the same thing in the next few years, At an avg of 45K a year I will want another motor in about 2 years or less currently 120k. And currently having the same conversation with myself either same 3.4L/w Super or non Iforce v-8 1UZFE. Was trying to figure total cost for each.

Yes, I definitely love my 4Runner, I wouldn't want it any other way. On a side note, I get about 21mpg on the hwy (@65mph taking it easy, it goes down to about 18 at 75 ). I drove my mom's 2wd 4Runner the other day, and I kept thinking there was something worng when i pressed the gas and nothing happened... I kept having to tell myself that I was missing about 150hp. 4Runner's were made to be S/C IMO.

Yeah, that's really bad, mmkay? You're leaning out because you have no fuel mods.

 

You mean the FIPK with heat shield? Your best bet is to sell that on ebay (I see them fetch $150+ regularly) and get a stock system back on there. Then, once you get the URD kit all dialed in, you can do the deckplate mod with Amsoil or Truflo filter. The deckplate mod is good for an additional 5WHP on the dyno.

 

BOOYA even if its a second gen. Keep on preaching brotha.. You've found a great support group here.

 

hmmm...if it was me, i'd save the $5k and put it towards a SAS...you don't need to go fast on the rocks

 

To each his own, I plan to get LT IFS and enjoy going 80 over the desert/dunes. Forced induction will definitely help

 

Im not sure who or why they threw out that number, but he drives a manual so the tranny isn't an issue.

SC 1850$ new
URD kit 1000$ new.
labor 0$ it's easy.

if you get those two and get it calibrated properly you should be good to go for about 3K.

 

His URD kit will cost something closer to $1146, since it's '98. Also, he will need a BR3 Scan Tool ($93) and a wideband kit ($350-400), plus a dual gauge pod assuming he gets the wideband ($70) (I'm also assuming he already has a laptop). When all is said and done, you should plan on spending about $3500-$4000 depending on what kind of gaskets and belts you replace along with the install. And of course, almost $5000 if you are auto and need the VB upgrade.

I'm just throwing out what you will want to have saved up, because it would suck to get delayed due to lack of proper planning..

 

Sorry to dredge up an old thread, but I've been looking into a Supercharger for Project SportRunner. This 2002 4Runner SR5 is my third Toyota truck with the 3.4L and I've eye balled the SC with each vehicle, but always steered away from them due to all the "extras". I downloaded the install instructions yesterday and it looks pretty easy to do. One thing I saw was the FAQ at the end of the document. Those FAQs went over adding new injectors, or transmission upgrades etc. Each time the TRD doc says nothing else is necessary. Now I know you guys have tons of experience with this thing and are living proof that the fuel and auto tranny upgrades are a must, but my question is if Toyota claims they're not IN WRITING and even IN THE INSTRUCTIONS at that, wouldn't that make them liable for the damage that occurs when you don't upgrade these extra components?

Page 18 of the instructions even state that installing the supercharger does not affect warranty at all, and in fact if you have the dealer install the charger even it will have a 5 year warranty.

How is Toyota not losing their ass with blown tranny's and burned up motors with this statement?

One other question. Does the VB upgrade make the truck shift more abruptly? I'd like to have the add'l torque of the supercharger, but I don't want to lose the nice drive ability my 2002 4Runner has now.

 

Yeah, i installed the S/C on my truck before finding this site. I dont have any mods done xcept the the free fmu mod. Not a big help but enough to get me by. So far i havent had any problems with it pinging, but thats because i have been a granny driver latly(free fmu mod sucks gas down). But anyways, i need to send my S/C(1st Gen, Grey) in to magnuson soon. Sounds like a bearing is going to let go very soon. While i have it off, im most likely going to get the urd kit and install it while everything is taken apart.

How hard is it to swap out fuel pumps? i know on some suv's theres a plate under the back seat that allows access to the fuel pump w/o dropping the tank itself. do the 4R's have that? havent bothered to look yet.

Ohh and with the cost of the S/C & urd kit the grand total will cost me $2,000

But anyways, kennyracer77, How you like it?

 

How many miles are on your charger for it to need service?

I'm weighing it all here.

In most of my analysis over the years performance usually costs $100 per HP gained. If the charger adds 75 by itself that's only $25 per HP which is awesome. Add in another $1000 for the URD fuel upgrade and $600 for the auto tranny VB upgrade and you're still at around $40 assuming the fuel upgrades bring your total gained HP up to 90HP. This is all assuming you do the work yourself.

However, dumping close to $4K into a 5 year old 4Runner is the decision I'm having trouble making.

 

Same issue I had. Your almost better off buying a rig with one in it!

 

I bought the unit used off my buddies aunt who t-boned somone(not her fault). And the stealer ship tried to say the S/C was bad to keep it and resell it.

My truck had 98k on it when i put the S/C on it and im not at 106,700 mi.

she found the original reciept when it was installed on hers and it was like @ 55k and after she took it off it was at 160k. So its looking at a good 100k - 150k ish give or take.

 

I would get that SC'r rebuilt ASAP, especially if the oil hasn't been changed in it. If it gives up the ghost, it can ruin the entire top end of the engine (according to Gadget anyway).

Magnuson was awesome. I have a thread about them somewhere on here...

You have to drop the tank to do the fuel pump. It's a 3-hour job from start to finish if you're decent at wrenching. I did mine alone.

 

ill probly be taking off the S/C this weekend. and putting the stock manifold back on for now, or just cover it all up real good and use my bros super duty for a while. i just saved up enought for the urd kit then the s/c started getting louder from when i first put it on. and im pretty good with gas tanks. Took the gas tank off my 88 beretta 3 times in one day, and the first time i took it down it was full. atleast it is low to the ground to begin with. but a pain in the arse to manuver through a straight welded exhaust.

 

Just for your reference, I made a write-up for installing a URD kit on my website ('98 4Runner), and it covers installation of an aftermarket fuel pump.

URD Fuel Upgrade Kit Install

 

uhh ohh, looking at your pics on the injectors part. i noticed you have the free fmu mod. i connected my boost part to the wrong thing . i hope i didnt hurt anything by doing so. looking at the pic that 96runner showed me was the wrong regulator connected the boost port to the regulator on the TB. this will be changed immeadiatly. i didnt know the fuel regulator was on the far back side near the driver side. i went and tried to find it and couldnt see it.

 

Lemme jump in on some of your other questions...

If you burn up your engine, Toyota will deal with it provided that you don't have anything extra installed. I think there are people around here that have gone that route.

Much of what we preach is based on watching things like EGT and A/FR and knowing that the numbers on an un-modified install are just wrong, and in the "damage" zone. So, call our babbling "preventative soapboxing based on paranoia according to physics with occasional pieces of empirical data". I mean, it's not rocket science to get from 1550* EXHAUST temps to "you burned a hole in a piston!".


I think you and I have talked about this, but I have a thread running called "3.4 rebuild" that has pictures of the aftermath of running lean - and I _did_ have the mods. Something went south, we may never know just what.


Correct.


Depends on what your threshold of "drive ability" is.

It kicks pretty hard, not like a drag car, but hard enough that you'll lurch as you drive around town. Some folks turn down the adjustment on the kick-down cable to soften it a bit. Personally, I lived with a slipping tranny for so long that I _like_ having that kick. You KNOW that sucker's locked up!
