  1. also posted in toyota performance, sorry.

    ok, i am in australia [if that matters], and i have a 78 RA40 coupé.

    it runs a "stock'' 18-rc sohc.

    i dont want to run a non-crossflow head, as it hampers my performance, and restricts boosting options, due to space contrictions... [temporary blow-through setup, tb03 turbo, 38dgms weber ect].

    this car is earmarked for a 1g-gte conversion, so dont just say swap the engine.

    what i want to know is, are there any sohc/dohc crossflow alternate heads for said engine?

    and on what vehicle are they most commonly found.

    thank you for your assistance.

  3. ohhhhkaaayy,

    for a custom 4a-gte i say one of these:

    garrett gt25---good response, ball bearing and can safely boost past 25psi

    garrett gt 30 as above but bigger, 30+psi

    garrett gt45 for total overkill drag-racing motors, pick a psi

    or if you want useless wa|\|k factor, as this will not spool, a trust T-88-34D.

    or not...lol

    but go the garretts. :thumbsup:
