    Looks like it’s time for an upgrade. I’d like to make 700whp if possible. I’ve decided to go with a teksid 4v build but I’ve got a few questions. Will my supercharger work on a 4v? What will I need to do fuel wise to support that amount of power? Any suggestions on where to look for a teksid engine? (Preferably no donor car) I’ve been looking on eBay and a few other places but I’m not entirely sure what I need to be looking out for. Any suggestions?

    Let me ask
    Why not run 2v to achieve the 700hp?

    Fuel wise: I plan to convert to a return style to support that power goal.

    I’ve considered that I’ve just always liked the idea of having a 4v. The guy helping me with the build favors them too. I agree I could get that power but won’t a 4v flow more than a 2v?

    Thanks for the link man! I like the idea of a return style but that’s all new to me and I’m not sure how to go about it.

    I’ve got the Trick Flow Race 195cc heads. I don’ t know if they’ll out flow 4v but they should put up some substantial numbers.

    I get it, the 4v does look 10x better and yes they flow well enough to run 6sec in a quarter mile straight out of the box, but certain aspects of the head make them not as reliable, although easy fixes. Locking out the chain tensioners and routine monitoring are needed, but not really required for 700hp. Best part the 4v valve springs handle the boost no problem. 2v pi head springs are really setup up for whats needed and a little extra. So thinking out loud, i see why the switch make sense.

    Found an 03 cobra motor with 14k miles that comes with the stock Eaton for $7k. Almost wonder if that’d be a better option than trying to throw everything together on my own.

    Probably - the front SC brace is the biggest challenge. A complete engine will have that.

    I would think the 03 cobra engine almost be a direct swap. Get it tuned out, be ready to roll out!

    Success rate would be much higher
