    Have ordered gaskets and ARP head studs from Mace engineering so will get this thing set up and ready to drop in ASAP. I've got a set of spare pair of Ecotec heads that look good but think I'll give them a valve grind and new stem seals. I'd like to give them a tickle in the ports remove some casting marks and reduce the protrusion around the the valve stem. Exciting times but it's been 20 years since I've swapped a car engine and not one with so much ancillary shit sure I'll be fine as long as my garage roof doesn't fall down.

    New engines getting some ARP head studs gaskets and another sump with a bigger drain so I can tee the catch can in to it. Might squirt some paint on too. Bought all the stuff 4 years ago it's just been on shelf waiting for this to die.

    I never intended to turbo the current engine I just mocked everything up on it and well it ran and continued to go and go. I finally got the tune on point and got a few good rips out of it I just probably shouldn't have got greedy and dialled up 16psi easily 400+ HP at that boost, smoked up the 275s stomping it at 80ks it then lost crank sync made a horrible sound and stalled. Restarted and sounded like hammers in a clothes dryer. My guess the crank pushed forward and side loaded everything or ate into block it has 3-4mm of end float so the thrust bearings fucked out years ago. Its had a ticking lifter at idle for a few weeks its possible it's that. but I'm not hopeful I've thoroughly beat snot out of it since drag day it had a great run.

    So as you do dragged out my spare block and realised my scored bores turned out to be schmuts that wipes off with CRC fan bloody tastic it's good to go let's whip the sump off check the bearings, even better they're mint no end float so I'm going to order some bits and get this ready to throw in. Even better it's a L67 so is boost friendly already. A list of abuse this old engine has tolerated Multiple 220kph runs down a airfield runway most mornings for 12 months 20,000k services while I was doing massive ks a week during Covid working in Auckland from Waikato. I ran it on waste kerosene for about 6 months Ignored 4mm of end float for 5years so much so it would lose crank sync occasionally and I'd have to push crank back with my foot for it to start. Fitted a turbo at 500000ks ran at 10psi for 6 months with basically stock timing (I pulled a little out but always ran 100octane) 40+ passes down the drag strip. And finally the 16psi of boost that killed it. I'm absolutely OK with how much this thing has tolerated what a trooper! Now I've had a taste of what it's capable of I'll get this new engine together and maybe fork out for some dyno time. 12's at drag day this year is the new goal.

    Well Flashed in the Big Beautiful Tune Today i've been working on took for a test drive, Ultra Peppy let it warm up a bit before leaning on it too hard 70% Throttle breaks traction at 80kph WOOHOOO! on same boost. took a log everything is happy gave it a full stab holy shit. checked logs again yup nothing to worry about lets stick 2 clicks in the boost controller........ WAAAAARP..........shit. so 2 clicks is too much.
  6. Muncie
    Woohoo!! Spun it to 6200rpm last night log only showed 2 knock events (not audible) in transition and I've got a whole heap of headroom now to up boost and have timing adjustable to go with it. Its ultra rich with weak timing as basically I'm starting from scratch again but I think I've got my head around how to get it set up and make decent power. Cheers HP academy without which my rods would have fallen out a long time ago.

    On another note did some more tuning got the new version that can be tuned all the way past the moon out to about saturn! Behaving nicely had to do some bizarre shit to the timing but I've now got it not freaking out under boost. Turns out what I thought was degrees of timing was an adder/subtractor number what I was looking at was plausible for timing numbers but wasn't....... More you know. So now I know which way to alter things to get the timing output going where I want it.

    Picked some scabs today as they were getting pretty worrying rust oozing out clearly some bad bad work in the past. About 5 mm of artisan applied schmoo! There's more cracking up further back but it's not open to the weather yet, plan will be dig out the bad stuff get some etch primer on and back fill and blow the sides of car the original colour again. Will sleep a bit better tonight knowing what was under the paint, was bugger all really but under bog it looked major.

    Made some center caps off aliexpress bits for about 10 bucks long wheel nuts are yuck ill get to those soon

    Well just learned if you blow an intercooler pipe off after the MAF turbo moves so much air through the system the injectors go max duty cycle and foul the plugs near instantly...... I rolled 1.5ks home and made it up drive and couldn't push brakes hard enough to not go into fence so handbrake to rescue! I may need to extend some pipework so I can get everything pushed in nice again, pretty sure I rushed the installation of the maf too maybe left a clamp loose. Goes great though!

    Nice and cold tonight quick squirt up road to grab dinner. Way more induction noise than before maybe the old maf was a restriction. Logged on weekend upt to 4000rpm air/fuel is safe could do with a bit more under boost to get it to magic 12:1 fuel ratio recommended on these things it's only mid 12.5:1 so I won't stress for now. I need to get the Blow Off valve on I'm paronoid of blowing another turbo. Overall big MAF appears to have fixed a few things it appears it wasn't as rich as I though once warm doesn't stink like first start so I could pull some fuel out on start up. Feels faster but I've been driving a diesel Holden Colorado all week could be placebo. Going to pull some timing and tidy up fuel a bit more..... Maybe crank it up to 15psi see what falls out.

    Current engine is starting to get a bit of a rattle at idle and on logs it's starting to lose sync on Crank angle sensor occasionally. That end float I've ignored for 5 years is starting to get worse. I've got a supercharged block with 2 scratched bores, I think I might try honing them see if they "Buff Out" and replace the 2 pistons if damaged. That'll get it a strong bottom end for a around a 1k. If not rebore and new standard pistons is probably reasonable too.

    Chucked in new airflow meter today fired up fairly easy running quite rich so I'll need to adjust fuel to suit. Just fudged wiring together till I'm happy to wire in permanently soldered ends and jammed in original plug. Its linear on wide band though so I could be able to get away with fudging some injector tables to bring it back in spec.

    Pm me what ya after will have a think

    I have been eying up some massive BMW brakes for quite a while but they would need some machining im just not up for at moment. I've had this thing up to 220kph now and there its still pulling hard at that when you see sparks as your slowing down it makes you nervous, Keen to hear how you go with the vf upgrade once your done.
