okay i like the Jardine exhaust idea. The URD is out of my price range is there anything similar i can get for cheaper? thanks for all the help guys.

 

If you can't afford the fuel mods you can't afford a SC IMHO. Or I'll put it this way, you can't afford the engine damage.

 

throw in some 4.30 diffs

 

still sort of lost thinking about air filters. i figure if i am going to do an exhaust upgrade i want to do air filter as well. i havent heard great stuff about K&N so anyone else have some idea on filters not as high maintenance but a filter that will be an upgrade.

thanks -matt

 

Just do the "deck plate" and "elbow" mods and keep the stock air filter in place. Save your $$$ for fuel mods, seriously the SC will force the air in just fine. You need more fuel, not air. I run 10+psi of boost with the stock air box and filter.

 

I agree with mt goat as well on the fuel upgrade since you have the s/c, but honestly, to get the most of what you have, fuel management and proper exhaust flow are important. I have DT headers and love them (minus the PITA install...). Further back than that, be careful as to not get too big of exhaust piping. Too small or too big, both hinder the overall performance of your engine. It all depends on what you want to do first I suppose. Spending money on that s/c, you'll want to get the proper fuel mgmt with it though...

 

Does anybody know how much horsepower the stock injectors are rated for?My stock integra gsr injectors can handle right at 300 hp. So is the 7th injector really a must have. Do factory supercharged trucks come with the 7th injector kit?

 

As far as I know there weren't any 5VZ trucks from the factory with a SC. The SC was an add on thing and some dealers may have added it on.

thanks for the advice ill look into that.

 

Thanks for the info on that mt goat.

 

At the very least make sure its been setup using the "Free FMU mod" described in that 2nd link and in the new SC install instructions. If you need the new SC install instructions they can be found online here: http://customtacos.com/tech/index.php?article=45

Doing the "Free FMU mod" will increase the fuel pressure as you increase in boost pressure.

 

Unfortunately the Jardine exhaust is discontinued for the 96-02 4Runners due to lack of demand. However, I picked up a 99' Tacoma Jardine full cat-back exhaust from URD when they were on clearance a couple of months ago for $79 bucks! I then took it to my local exhaust shop where they modified to fit my 4Runner. I paid $60 to install it. So I got a $300 exhaust for about 140 bucks installed. Call up URD and see if they have any more of these cat backs sitting around.

I also performed the deck plate mod with a K&N drop-in filter. The full K&N CAI is rated at about 8 hp gain. I probably picked up around 5-7 with just the deck plate and free flowing filter and it only cost me around $60, which is alot cheaper than $300 for the full CAI.

 

Texas Ace had some interesting dyno results here comparing a stock air box to a "CAI": https://www.yotatech.com/forums/f2/t...begins-146485/

Maybe the results would be different for a non boosted engine, but clearly the normal mods that people do to increase air flow for power become at best insignificant with a supercharger or as in Ace's tests actually decrease HP.

Then there is also the possiblity he is has already boosted the air intake to a lean condition and adding more air just makes it worse.

I think anyone running an air metering system that uses a MAF (mass air flow sensor) is asking for trouble using an oiled air filter.

 

Do you know what the mods that were done to this exhaust? I just picked up the same one for my 98 and now I just need to find someone to put it on! Any help would be great! thanks

 

The jardine system is just a muffler with 2.25" pipe, mandrel bent though...

Install it yourself; it's pretty easy.

 

But I bought the exhaust for a Tacoma, and I have a 4runner, it should not be a problem to fit right?
