    3VZE Upgrades - Looking for Suggestions

    Hey Guys,
    I am currently doing some minor mods to my 1991 Pickup 3VZE and was wondering if you had suggestions for a cold air intake system.
    My plan was to remove the stock airbox and just put an filter on the inlet to it, skipping the whole box entirely.
    Any idea's on a good air intake system you can get in Canada?
    Also, looking at an electric fan conversion as well. Suggestions on that?
    I was going to install a Borla Turbo muffler, any thoughts on that? LOVE the sound matched with the 3VZE.

    Any other cheap performance/easy performance mods you guys can think of?
    Insight welcome, thanks!

    save your $$ and don't buy any of that and instead swap the motor with a 3.4!

    skip trying to make an air intake just put in a factory style K&N filter in the airbox, I am running the a borla setup very pleased with the sound. I just ordered a set of the Thorley Headers to help out, they will make a huge difference with power about 10-13 hp. I'm also going to drop about a $1000 on getting the heads done. I talked to magnem machining in burnaby. Most will rant just to put a 3.4 in it but I like the 3.0s there a solid engine, they just need a little help to produce sound numbers. You can also check out http://doaracingengines.com/ I'm contimplating getting the bored throttle body but not 100% convinced on overal performance, I will be doing more research on the TB.

    If you get rid of the stock airbox you won't have an airflow sensor. It's located in the top of the airbox. It will result in less power and a shitty running engine.

    93 Toyota flatdeck 4x4 (Sold that too)
    96 F-250 Powerstroke. It's got me to work in Fort Mac, and took me on vacation to Baja California.

    DO NOT REUSE THE FACTORY STYLE AIR BOX! The factory style air box on 3.0L trucks and 4runners takes air from directly behind the drivers side headlight. If you hit any sort of deep puddle and water rushes up to your headlights your fucked. Bam goes the 3.0L. Your best bet is to purchase a k&n cone filter and an adapter for your mas air flow sensor. Then re route the filter up near your master cylinder out of the way of water. I plan on just using ABS pipe but you can use stainless or aluminum.

    have a look under your hood. there is a tube that enters your stock air box and sits wide open directly behind your drivers light. the cone filter adapter just allows you to use your stock mas airflow sensor with a cone filter and get rid of the stock air box. The k&n FPK system uses the same principle. kind of like this:

    Make your own intake. I made mine out of 3" exhaust tubing, 2 rubber couplers to attach it to the TB and Stock airbox and two brass fittings threaded in for the two lines going to the intake (to the valve covers). Cost me $25.

    I do like the stock airbox tho, I hate k&N filters and toyota air boxes sound like screechy ass when you throw one on...

    don't expect performance gains from an intake aswell. The exhaust hurts the motor alot more.

    Re: 3VZE Upgrades - Looking for Suggestions

    here is the after pic of the air box removed and changed to k&n filter setup with a few more mods i put the air flow meter right @ the intake {better throttle response time}


    taking out the air box gave me room to install a second battery



    i also drilled out the center of the old pcv valve and put new pcv hose on it and ran it to a new location put on a new pcv valve and a new hose and ran that to intake {now i never have to take off the upper intake again to change pcv valve}



    put a breather valve on the driver side where the hose comes off the valve cover {no oil going into intake and it looks cool}



    and last but not least put on new and Bigger ground wires to the block




    If u need Help with these mods pm me i will as much as i can
