    Engine Rebuild or Crate Motor ??

    Have a 253 that was running, 18months ago when it came out. Since then it has sat on shed floor un loved collecting dust.
    The time has come for it to be replaced in the chassis.

    Currently looking at sourcing a Supra 5 Speed Gearbox to put behind motor. Long distance country cruising

    Motor is going to need a freshen up so am after some ideas as to which way to go in the engine department.
    Currently located in Country SA

    Thanks for your help in advance

    If you are going with the 253, the simplest things for a big improvement are;
    Standard top end rebuild if it's worn
    4 barrel manifold and quadrajet carb
    Mild cam
    Leave the standard size vales in the heads
    Blue motor electronic ignition
    Extractors and a nice twin system

    Make sure that you can run it on Unleaded without additive and if possible regular unleaded.

    As above for a rebuild.... Or, leave it on the shed floor & grab a VN 5.0 litre + manual box. Fairly cheap and easy to find & go quite well. Otherwise a later LS engine, they go hard, but don't look the best under a HQ-Z bonnet (in my opinion)
    B.T.W. I have a HZ ute with 253 + supra bpx, & don't like the ratios much

    cheers

    253 is a sweet LITTLE motor. You can extract some awesome performance. But if you don't have a machine shop, go big or go home. Sorry but I have spent over 100 hours in a machine shop to get what I want. Go 308, stroke it if you have to but bang for buck do your homework.
    Should have asked if it is the original motor ?

    Thanks wbute and Vombil.

    That's pretty much nailed what I am after.
    Mild cam and carby change.


    Its just the costing of doing rebuild verse pick up turn key motor.
