    Justin is going twin turbo...

    sweet man go for it! Why not get really into the fabrication and hook those suckers under the hood and then you could ditch the scavenge pump for some $$$$ and no oil drainback problems?

    turbocharger selection.

    I run a chrysler 10$ T3 .42/.48 on my 4.0 under the hood. It suits the 4.0 just fine for what I wanted but a 302 will be very different youll need a larger turbo or 2 T3s

    my diy 4.0 ohv turbo build

    Well first of all i push things farther than most should. Second no there is no tune, fuel, intercooler, or recurculation, and the O2 isnt hooked up im just running open loop.

    my diy 4.0 ohv turbo build

    im enjoying it i still have some work to do. the bov is venting to atmoshpere (at idle the bov is closed) unitl i build a reculculating bypass and it stumbles after a blowoff if im not on the throttle quick enough but its doing pretty good for not even being tuned. Soon a bigger pump will be...

    my diy 4.0 ohv turbo build

    I built a flange for the turbo last night it still needs a little porting that ill do tonight on break. I did some moving on resivoirs and deleted the ac compressor for more room. Then started mocking up where the turbo will sit.

    my diy 4.0 ohv turbo build

    I flipped the driver side manifold so i can run a pipe under the bellhousing to Y with the outlet of the drivers side manifold there is where the turbo will be placed. Plan is low boost no more than 5 psi on a draw thru design with the recurculating bypass. i had built a temp down pipe to...

    Need Advice on Supercharging

    fmus are junk all they do is restrict the fuel at the return line under boost to create excessivly high fuel pressure its not an accurate way of tuning. The setup will most likely run incredibly rich. you need to tune the ecu to map the new fuel curves

    4.0 Remote Turbo Buildup

    yeah i would weld in a setion of pipe to reinforce the hole. bolting two plates to the frame isnt going to support the frame as well if at all

    ...manifold that is. Im planning to turbo the truck down the road soon here after i complete my curret TT car. I plan to make it a budget build. I already have tons of pipe and oil lines. I just need to scavenge the yards for a good sizeable turbo for this application. Ive already flipped the...

    Need Advice on Supercharging

    centrifugal superchargers generally build more upper rpm power. It still may be a little sluggish coming off the line but once its up to speed :thumbsup: also youll have the motor going before the bosst starts showing so that will help. Eatons and whipples build boost fast at very low rpms which...

    air fuel gauges

    you atleast need a wideban 02 sensor to go along with the gauge. its not compatible with factory narrow ban
  30. T

    air fuel gauges

    factory O2 sensors are narrow band sensors. Dont waste time with a cheapy narrow ban gauge. Get a wideban kit. Look around for good deals on the inovative or AEM wideban kits.

    turbo 4.0 ohv

    the motor is a nonpi 281 (4.6) with a few goodies like stage 2 cams. Actually in my setup the oil is a gravity return. I have a stand alone setup. The resivoir is below the turbos for a gravity return using the shurflow to pump oil from a bottom port to the twins. It's still being built i just...

    turbo 4.0 ohv

    all the pipe i dug out of exhaust shop scrap bins. The falnges were cut out of stainless by my father. The turbos are 2 T3s off of the older chrysler turbo four bangers. The 50mm waastegates are ss autochromes with a shurflow pump and i modified an old air tank to be used as a oil tank for my...

    turbo 4.0 ohv

    you can have a remote mount for cheap. you need a turbo or turbos with small exhaust housings. Heat is lower after 10ft of exhaust but the smaller .ar will help spool the turbo. you also might want a smaller pipe to keep velocity up. You will need a scavenge pump to return the oil to the motor...

    Going twin turbo. 4.0 ohv

    boost pressure isnt produced by how many turbos you have 2 turbos making 3 psi each to equally 6 psi dosent work. The twins will be easiest Ying the outlets from the compressor housings into the manifold. You will need to have a vaccum line from the cold side to the wastegate(s) whatever the...
