  1. I had a new impeller fitted and used vortech themselves in the states I took the opportunity to upgrade to the si impeller over the sci which netted a few more psi 

     

    I definitely wouldn't trust anyone other than vortech to do the job and I don't think they will sell you parts 

     

    This being said I did come across a UK guy the other day thats rebuilding a load of chargers and seems to do things correctly so might be worth a chat with him regarding the aftermarket impellers you talk of

    Good luck

    Nice pics, it looks pristine.

    I'll be stripping my block down over Christmas and was wondering;

    Did you fit new rings on the same pistons or did you need a rebore and oversized pistons?

    Did you get away with std main & big-end bearings on the crank?

     

    Block was bored to take new JE pistons and we used the black ...I think they are grade 1 bearings on the crank

  3. Long overdue update on this.

    life well and truly got in the way this year and I ended up buying a stop gap love or hate the looks what a car it is to drive and dose all the family duties realy well so think it might stick around for a while.

     

    Anyway you're not here for that!

    now life has settled down a my focus is back on getting the z ready to enjoy next year

    so here's some progress pictures 

    I have also had a koyo rad matted to the stock ac condenser to keep things cool

  4. So finally had chance to drop the engine off to the machine shop today with @350Butcher

     

    It's gone to https://ricwood.com/ for the work my buddy has him build all his race engines so he should be good enough for my old z😅 we also managed to find time for a good old breakfast to fuel us up 

     

     

    The engine should be back in a couple of weeks and the build can start going in the right direction ready for summer 🌞

    I have always seen 1/4 to 1/2 thou change in measurements, it isn't just in the vertical clearances that changes when fitting studs. I am not a big user on Main studs TBH.

     

    Decided against them to after a chat with the machine shop today

  6. In a bid to keep the z cool with the new motor I thought a nice rad upgrade wouldn't go a miss.

     

    I had previously ordered a mishimoto rad as it keeps the AC but the quality didn't look the best so I opted for koyo and will have the stock AC condenser mated to the koyo 

     

    The welds on the koyo are much tidier than the mishimoto for a start so that a good sign some care was taken in the making of it 

     

    There will be a little trimming involved here and there  but at this stage we are far from stock configuration so it's all about what works from here on in 

     

    Heres some koyo porn

  7. Bit more work done this weekend and we're almost ready for the machine shop 

     

    I was hoping in a way to see a obvious failure but nothing was really apparent apart from  little  inconsistencies on the gasket as if the coolant and washed it a bit but that's clawing at straws.

     

     Hopefully It was just a case of what the yanks call head lift due to the massive cylinder pressures experienced when adding boost to a high compression motor.

     

    Once the parts are cleaned up a bit and the heads are stripped down it will go off for machine work and I'll have the block checked for any cracks etc but on visual inspection it all in realy good order.

     

    But as for the rest of the engine it's all in realy nice condition which is testament to a good calibration from Litchfield and excessive oil changes and maintenance.

     

    so if you're thinking of boosting and if it ruins your engine the answer is no just don't ad to much boost 😂

     

    So enough waffle here's  some pictures

  8. A little more progress today it's to the point of opening up now.

    Exhaust manifolds off 

    Intake manifold off 

    Remaining coolant hoses off 

    Fuel rail off injectors out 

    Coils and plugs out 

    I'll be sending the injectors for flow testing and cleaning before they go back in last thing we want is a injector ruining the new engine.

  9. I don't fully understand it all mate I was led by Bennett on the initial set up for boosted application

    The one thing I would like to do this time is have the ones that had filters on into cans that would be ideal I think.

     

    If I remember rightly it came down to packaging last time and the very limited space to put anything

     

    Theres no rush this time around and the engine bay might even receive some dress up 🤣
