It is possible, but more likely to break trying than if you build a bigger setup in the first place.
    I figured a turbo and head are in my future. And thats ok. As I've asked others, what would your suggest for a turbo assuming a good head setup?? Right now Im looking at the +1mm heads

    Re: Making an 89 Lebaron run in the 12s

    My goal is to get my full weight Shelby lancer comfortably in the 12's. I am fully confident that I will meet that goal once I build a shortblock for it. My rundown:
    TO4e 50 trim with .63ar and stage2 turbine
    TU cast exhaust Manny
    Shadow custom mandrel 3" sv and 3" full exhaust
    Lengel plenum with 1/2" spacer and Jeep 60mm TB
    This is what I have so far. Going to port a +1 swirl head myself and use either a fwd f4 or tu r5 cam. Also thinking of ditching my air to air for an air to water intercooler. I can't fit 3" pipes up front with a/c.

    - - - Updated - - -

    The lengel plenum and Jeep 60mm TB made a massive difference in drivability with the 50 trim. With a 2 piece it was generally laggy and kind of unfun to daily drive. Now it's amazing.

    Sounds like a plan👍 I assume (as I understand air flow characteristics would dictate this) that basically one of the custom intakes out there is required to utilizing on of these larger heads. I mean I know the stock manifold would be a joke compared. But on the flip side of you had a custom intake on a lightly ported stock head that too is kinda a waste???

    Cool! Am I to understand you currently have a stock head and cam then? If so you feel itís pretty happening as is?? I defiantly wanna get a turbo and head. Just wanna make sure itís worth the coin, and I choose wisely for my needs/vehicle/goal. What is the Lengel plenum. Iíll be searching for it. It in a summary is it a tried and true unit by you guys out there?? Thanks again

    A good turbo and good intercooler will get you in the 12's without running a honking load of boost.


    It is time, buckle up.

    I have a stock head and cam currently. I can't go to crazy turning up the boost because I'm on a stock t1 bottom end. Don't want uncle Rodney to come knocking.

    46 trim To4e stage 1 .63 A/R for power you need to go 12's and least amount of lag without going to a BB turbo.

    +1mm head is all you need if you want to go that far, but a well ported stock valve head is all you need.

    TBI or 88 turbo roller cam/ F4 if you want it to rev more like a stock 2.2

    I had a stock 2 piece intake manifold on my FM stage III big valves head and I had a BMF intake manifold on a stock cylinder head. The setup with the big valves head will make its peak HP around 6300rpm while the setup with stock head is making its peak HP just pass 5000 rpm. So, after experiencing what a good cylinder head can do, my personal preference is that I will start with a good cylinder head first.

    Think about it, a stock 2.5 turbo is rated at 150hp. A stock 2.0 n/a DOHC also rated at 150hp!


    What are you doing for EFI control?

    As of current using FWD Performance stage 5 with +40 injectors and 3bar map. But looking into doing the unit from here (canít rember the name) to either have some one program for me or work out my own. Itís the unit that has the small touch screen that is all been built by a member of the form

    If motor was up to the task then spray + slicks. If you just want a 12.99 then I think a lot of these expensive modifications are unnecessary. Many mods mentioned are wasted potential trying to go 12.99. Mild turbo upgrade and good fuel will probably do it on slicks.

    thanks you for that. Yeah Iíd be ok with a 12.9. Slicks are gonna happen. Iíll be also doing some of the mild options. With a few more expensive stuff just to make it get there easy. And be able to run on the top end. Thanks all!!
