    VNT and R/T Rad+I/C - all the same?

    Are all of the VNT (CSX/Daytona/Lebaron) and R/T (Spirit/Daytona) radiator+intercooler setups the same? I have an R/T intercooler, but I'm looking for a radiator to bolt it to, just wondering what all will work...

    89 CSX TIV uses the same radiator as my 89 TII Daytona.

    Re: VNT and R/T Rad+I/C - all the same?

    The VNT radiator that is used in the 1990 models is different from all others previous. An earlier radiator will not "drop in" to a 1990 Daytona for example. And the intercooler mounts differently starting on the 1990 models, as it bolts directly to the radiator end tank. I am not at all familiar with the R/T intercooler, but I know the fan mounts differently on those radiators than on the VNT rad.

    I went through a whole bunch of radiators friends lent me to try when I needed one for my Daytona VNT (and 1990 VNT P-body rads are smaller than 1990 VNT Daytona rads). I finally found a shop that could recore mine. All replacement rads available new are the wrong radiator, btw. The numbers superceded to an N/A rad and that is the one the book lists for all the 1990 applications now.

    The I/C I have bolts to the rad tank. It's definitely different than the '89 T2 I/C I had from my '89 Daytona (that I put into the van).

    the R/T intercooler bolts to the tank with 3 bolts and the lower pin and upper mount are part of the intercooler itself. On the other bodies there are metal straps across the top and bottom that bolt into the radiator and intercooler. the straps have the pin and upper mount.

    I don't believe so. The filler neck on a T-II Daytona radiator stick up a ways and will hit the hood on a Shadow. At least it will on a '90 Shadow.

    BTW Rob: don't use the vnt intercooler.... too much pressure drop vs. the others.

    No it is not. I tried a new one a friend had for his R/T and it would not fit. And the fan mounts entirely different on an R/T rad than on the VNT rad. My fan still uses bolts to hold it in at the top and slides into S clips at the bottom of the rad. The R/T rad fan slips into molded clips built into the radiator frame/shroud and uses a bolt or two just to keep it in place.

    90 is a year of its own, but i did get a r/t rad that was being used in a VNT car i am not sure how it was mounted i did not see that
    r/t rads are the same spirit to daytona

    90' Shadows are a one year deal for the radiators. 89' shadow rads won't bolt into a 90' and 91+ rads wont either.

    I do know that a 91+ R/T rad/IC will bolt into a 91+ Shadow. As previously mentioned 90' VNT stuff is 90' specific for the shadows.

    To be more to Steve's original point, the R/T rad should be too tall to mount to the 90' shadow, and it may also be too wide since the 91+ stuff was much wider than the 90' Shadow rads.

    Re: VNT and R/T Rad+I/C - all the same?

    Well, we've gone beyond what I guess I really wanted to know - what radiator do I need to put into a '90 Daytona to go with an R/T intercooler? R/T Radiator?

    I was thinking that the CSX VNT rad I/C was the same, but I guess that's not the case.

    Use what then? T2 Rad I/C? S60 I/C (assuming I can find one)? I don't really want to go front mount...

    I have a rad that you are looking for. I just saw you found my for sale ad, it's still available.

    Bill baker used a 1989 T-II rad in his '90 VNT and it cleared the hood via leaning the rad a bit. You could also have the filler neck modified...

    best radiator/IC would be the 90 daytona VNT, it would be direct and perfect fit,
    but they are hard to find....

    Agreed. The real question is what Rob will be doing with the car. If it's going to be fairly stock the VNT IC may not be that bad. I honestly don't know that the trouble to fit a T2 IC in there would be worth it performance wise. At that point I would just go to a front mount.

    Re: VNT and R/T Rad+I/C - all the same?

    My current plan (as always - subject to change) is a 2.4 with a 420a (front exhaust) head. The side mount I/C will work very well with this setup. Front mount could work, too. But, I already have the I/C plumbing in my head for the turbo and side mount. Is there a side mount I/C that's is similar to the TD style, but better? Ford?

    Re: VNT and R/T Rad+I/C - all the same?

    IMO there is only so much surface area up there to get the job done. I can't see running a stock style IC with a 2.4 or any 16v head unless going for originality. Take two TII rads and make dual core unit. You could get a pretty mean SRT4 triple core IC in front of the rad if you make custom end tanks if my calculations are correct.
