    250 Crossflow build

    Another old Melbourne XF Turbo originally built in the early 00's. Has hemi rods also. Sent from my SM-G610Y using Tapatalk
  2. https://www.hotrod.com/articles/build-blow-carb-less-50/ Here's another article on modding a Holley for boost. It would be a damn sight cheaper than buying a finished one. Maybe more fun too. Sent from my SM-G610Y using Tapatalk
  3. There's a link here for how to modify a 4 Barrel DP Holley for boost : http://www.hangar18fabrication.com/blowthru.html I know you don't really want to hear it, but by the time you've paid for an Aussiespeed manifold, carb, msd etc. You could have bought an E series ecu and J3 chipped it. Bosch Green 42Lb injectors, walbro 255 pump, fuel reg, xflow efi manifold & rail. Sent from my SM-G610Y using Tapatalk

    250 Crossflow build

    Yep with a stock valvetrain, just a decent set of valve springs, decent head gasket & fresh bottom end. Stock CR is perfect for a turbo.

    Change ba 6 to v8 351

    I'm not sure if you're serious but anyway. You could most likely fit the biggest fuel guzzling lump of cast iron you can find under the bonnet considering they had the physically massive 5.4 dohc from factory. The real question is why would you? Can you afford to do it? If you can then why would you start with a BA and not an earlier model which can legally run an old school V8 and be way cooler? Is it worth the fine if you get caught? Your car would also be uninsurable. You could just buy a BA XR8 or 5.4 3V, put on an exhaust and CAI, have it flash tuned and probably make more power than the tired boat anchor you put in there. It would go ok, sound good and would be legal. Sent from my SM-G610Y using Tapatalk

    HELP- Upper Control Arms

    There's a performance shop in Cardiff called Backtrack Performance. They've dealt with a lot of drag racing and drifting with Imports etc. They do fab work I believe maybe try them? Sent from my SM-G610Y using Tapatalk

    300 USA 6CYL

    You can apparently stroke a crossflow with offset grinding and a different combination of pistons and rods. The question is why would you? They're already well undersquare. If you need more torque beyond that, a smallish turbo or even a roots blower would fix that while producing more top end power. People go to extreme measures to counter the inherent problems of such a long stroke with the 250 as it is. Adding stroke would exaggerate these issues. The piston speeds would be huge with such a long stroke. The reason strokers are popular with American V8s us because most of them are well oversquare from factory and have a lot more head room to gain bulk capicity and still keep piston speeds sensible. The 300ci 6 is a different family with a 4" bore and almost 4" stroke

    250 Carby Turbo

    It's to do with the output of the e series map sensors, they aren't 0-5V GM style where you can just scale the map to suit the sensor i.e changing to a 2bar map sensor, they put out a frequency. You can get around the 10psi with a boost cut defender and rising rate fpr if you want more boost than that, not ideal though. Sent from my SM-G610Y using Tapatalk

    250 Carby Turbo

    If I were you I'd go efi, being a Ghia it should have been efi standard ? For a small budget I'd go with a factory xflow efi intake with some cleaned 440cc bosch green s/h injectors which can be bought cheap an e series distributor type ecu (along with a J3 chip) and wiring harness. A TFI dizzy if you don't already have one. Replace the stock in tank fuel pump with a Walbro 255lph unit, an aftermarket efi 1:1 fuel reg. A front mounted air to air intercooler. By the time you stuff around with buying the carby and associated manifolds, then tuning it you'll probably end up with a rough running,temperamental pile of shit. The factory e series ecu with a J3 chip allows total control over fuel and ignition for all weather conditions. I believe you can run up to 10psi before you run out of tuning resolution.

    Thinking of buying 98 xh ticford

    Pros: Having people tell you how unique and different it is going down that route. More power than N/A Cons: parasitic losses of a blower,boost rises with revs, it costs way more than the car is worth, limited resale market and therefore value if you ever change your mind, can't change boost level easily, throwing belts, less power and peak torque than a correctly sized turbo. There's way more runs on the board with turbocharging Ford 6's in both drag racing and street cars. Ultimately it's your money, different people want different things for different reasons.

  12. I'm not sure what size tube the lines are so here's a chart Sent from my SM-G610Y using Tapatalk
  13. You could get a swagelok or similar joiner so you can cut and rotate the tube. Sent from my SM-G610Y using Tapatalk
  14. Here's a CAD Alloy XFlow header flange for anyone who wants to make their own manifold. I've got it at 12mm thick for turbo manifolds. I've also got a dxf file to send directly to laser cutters to save coin having it formatted. PM me and I can email it. Sent from my SM-G610Y using Tapatalk
  15. You could drop in a 1J/2J
