I have tried searching but found nothing. Would it be a good idea to put a supercharger on my 1998 4runner with 148,000 on it? Would it reak havoc on my motor or could she handle it? I really want some more power so I thought this might be a wise investment?

 

Really depends on how it was treated its whole life.

If it was babied with synthetics, and driven easy, then a supercharger would be ok.

If it was beat up and driven hard, you may want to hold off until its time for a rebuild so you could do it right.

 

Well since I have owned it she has only had the best as far as filters and synthetic oils. I really dont know about the time before I owned it?

 

148K is baby miles for a toyota. A blower wont hurt it as long as you maintain you eng right and your fuel system is operating correctly. Abuse your truck and you will be asking for trouble

 

Yea I work for a parts store so I have no problem maintaing it. It runs great!

 

you should have no problems then! Buy me a S/C while you are at it k? lol

 

Were is a good place to pic one of these up? preferably new.

 

new is from the dealer mainly since toyota ownes TRD. You will be looking at anywhere from 1900-2600 depending on who you get it from. Look for used low mileage blowers on ebay. Ive seen alot and you can always get them for less than 1800. If you have a wholesale acct you may be able to get one cheap from the dealer

 

I have always been told that you should have a compression test (and leak down test if needed) done before going to a forced induction system. If all cylinders are within spec the miles shouldn't matter.

 

This is where I got mine:

Great service and prices!

 

Dealer quoted me $3,800 for the entire kit.

 

I purchased mine on ebay brand new for a little over $2K......... there's usually a few on sale everytime I check.

 

Did that include the TRD 7th injector or something? Sounds pretty steep unless it included the 7th. Mine was about $1950, new, from the link I posted earlier. I did spend another $1000 for fuel mods (URD) http://www.urdusa.com/

Don't put it on until you can do the fuel mods too.

 

You really dont NEED the fuel mods unless you are using a smaller pulley. Its not a bad idea tho. At least a 7th injector would be good.

The dealer is lookin to pay for his vacation by quoting you $3800 for that. Shouldnt be any more than $2800 at the most

 

I second that. Also the IPT valve body mod is something to consider if you have an auto trans, but its not necessary immediately. All this might sound like a $$ trap at first, but its def worth it and will save your 4Runners life if you do it right from the beginning.

 

Well Iam stuck between puttin the money into a suspension and other thing on my 88 pickup or a Super Charger. Decisions Decisions......

 

where can i find crome rims for 01 4runner stock chrome.

 

So I went to the dealer and they priced me out a TRD Supercharger kit for my 4runer at 2800 bucks. I dont think that is too bad for one. Iam gonna start saving. Iam half way there! In the kit does it come with a boost gauge?

 

Also how much tuning is really nessary for the install?

 

From my personal experience, I would advise adding the SC. However, it should be done in proper order and set up correctly to give the best performance and longevity to your engine. My recommendation would be:

1. Buy/install a REAL AFR (air fuel ratio) meter - not just LEDs. Install it and get use to monitoring your fuel mixture. It is a MUST to correctly assess the mixture if you want longevity with your performance.

There is a "lean condition" documented that created havoc with some engines. With the TRD 6 psi pulley, you are likely to be OK, but you want to be sure.

The AFR meter's sensor would mount in a bung welded in your exhaust down pipe, so if you are considering adding headers, you could do them both together.

2. Get your SC "new", but an OTS TRD Gen IV unit exceeding $2200 would seem excessive to me.

3. If you have an auto trans, a valve body mod is suggested. (IPT of NJ can do that on a quick-turn if you ship it to them for about $500). They provide step-by-step instructions on how-to. Manual trans - ignore.

4. Install the SC and drive it carefully. Watch your AFRs for all conditions, but especially when you go to WOT (see if your fuel system is able to supply the required fuel). If the AFR is higher than say 12.5 to 1, you may want to consider the URD fuel upgrade kit. (If you are MUCH leaner, you have no choice). Most AFRs for stock-pulley SC 3.4s will be OK, but some aren't.

A boost gauge is also good idea, but not critical. A fuel pressure gauge would be a luxury too, but not required.

5. The URD kit that includes the tuning calibrator, (piggy-back for the ECU) provides the optimum setup. (You would also need an OBD II scan tool ($80) and a cheap laptop to do your own tunning).

The URD fuel Kit is a complete solution, containing the larger injectors, fuel pump, Iridium plugs, thermostat, and other essentials that do the job VERY nice. It adds more horsies than the TRD SC alone, while eliminating any fuel mix issues you might have - OR WILL HAVE.

(Add the URD 2.2" pulley too if you want even more fun). The 3.4L engine loves this combo and runs excellent - with no threat of ills - as long as it is set up correctly.

6. If you can't go "whole hog" in buying all the accessories right-off, then do it in increments. Contact URD by sending them an email. They will give you sound advice that will help you do what's right for your situation and help you work within your budget.

They might even have a "little something" you could add on instead of TRD's SC. ......Check out their web site!

My only regret when doing my truck was me adding it all on at once. I did not observe the stock fuel system behavior before throwing in all the money. I might have made better decisions - who knows. But the end result was totally impressive.

I installed the TRD SC, the URD fuel kit and 2.2" pulley, a trans valve body mod, a trans cooler, and the headers too.

Wow, what a difference!

I have a ten year old truck that I still love driving every day.

Good luck with whatever you decide!
