Some progress of sorts...

The sort of progress one makes when the engine starts to run that is!!! :D

I had a remote diagnostic session with Mitch from Haltech on Thursday and I am extremely grateful for his time and even just the concept that time was given in support of a well and truely outdated product! THANK YOU MITCH AND HALTECH!!!

The ignition timing refused to act predictably during the remote session. A number of different checks were performed and a few of the many combinations of home and trigger compenstions etc. Even though the session ended without the engine running properly it was a HUGE help to my sanity and I gleaned a few insights to some of the ecu settings. Mitch left me with the suggestions of converting my VR sensor system over to Hall Effect sensors and/or changing my four flying magnet crank trigger to standard trigger i.e. removing two magnets.

As the immediate option available to my shed based tinkering was removing two magnets from the crank trigger I did just that of Friday evening. The ecu was then instructed that it has standard trigger instead of multitooth. I spend the next half hour with coughs, bangs, and sheets of flame from the intake before hitting on the combination of reluctor compenstation level 5 and motronic compensation level 2 for both sensors and next thing the engine was idling happily. After about twenty seconds of nervously waiting for an enormous backfire or similar I approached the engine bay and blipped the throttle a few times! It was getting late so I left off work till Saturday at which time I spent some time getting the timing mark on the balancer to spot on match the lock timing request of 20 degrees. I revved the engine up a few times and the timing stayed ROCK SOLID on the 20 degree mark! Most excellent! Next up is to get enough of the wiring inside tidied up and a drivers seat bolted in to see how it drives.

In other news my supercharged outlaws buddy decided a couple of months ago that he would like to try this turbo thing. Enter a second hand 454 cube big block chev crate motor scored for 500 bucks a pair of mack truck turbos, a box full of ricer bits and an old fella asking me if it would all work with the ancient predator carb sitting on his shelf! :eek: I said sure it will if you agree to put that predator carb back up on the shelf and let me put a holley carb on instead.

Apparently everyone else says it won't work so the old fella has gone out on quite a limb trusting me here... So my old 650 holley I was running on the celica as well as the MSD programmable ignition have made their way onto the engine and him and his mates have fabricated everything else mostly as I requested. With everything installed and wired up in the spare race car it was initial fire up time on Friday arvo. The beast fired straight up to life and apart from a couple of water leaks to be sorted it all appears far too happy! Being supercharged boys from way back the sound of the near standard 454 running through a pair of turbo's was not very inspiring for them. They were still laughing like idiots and consuming beers when I left a few hours later once I had demonstrated the crack-bang-huge-flames anti lag launch however!!! :cool: The anti lag is purely for amusement factor and crowd entertainment as with an auto transmission it is useless for staging but you've gotta have a bit of fun now and again eh??

Jason

Did you swap for EFI Helltech Jason ?

:D NO! :lol:

The Haltech E6X is purely in place for controlling sequential ignition with my IGN-1A smart coils as I wanted much more stable ignition timing than the distributor based system gave me last time.

Fuel wise for now I am going to see how far I can go with my own modified Quickfuel 650 carburettor on E85.

LoL as piggy style but only using the ignition ! Smart either way if you run out of fuel in the top you can mock few additional injectors :lol:

Because I can!

:lol: :lol: :lol:

Lots of work still to go. Windscreens front and rear, finish tidying up the wiring, iron out some more electrical gremlins such as the lights, sort out the transition on my Holley i.e. get the HSAB's correct, and put the hood back on!

Anyhow it was fun to take a quick drive up to the end of my street and back because this has been two years in the waiting! :D

Hmmm - yep it all turned to putty! :lol:

Then engine builder had taken ZERO care and so main bearings were stuffed as were the cam, lifters and pushrods all within 20 minutes run time.

So I organised a brand new billet comp cams bump stick and a set of nice new lifters to match a full new set of engine bearings. I have thoroughly washed out the engine block and all components being re-used.

The support bolts for the main studs in the girdle had been nipped up which had caused direct contact between crank and bearing. I discovered this when I was reassembling the bottom end myself. If I gave each or any of the bolts an eighth to a quarter of a turn past hand tight the crank became hard to turn. Having been nipped up previously the top and bottom of each main bearing had been gouged out leaving the sides if pristine condition. I did them hand tight before nipping up the retainer nut which will lift the bolt a woofteenth away from the cap leaving it in place purely for support in severe flex situation just as it was always supposed to be for...

When I went to install the brand new lifters which are identical in diameter to the old ones they just plain wouldn't fit unless you hammered them in. :evil: I had been at the engine shop when he went to fit the lifters on this build and they had been tight then - I just didn't know how tight. He had put a cover on the engine and said he would sort it out in the morning which plainly did NOT happen... I had to spend a quality morning honing out the lifter bores.

The cam had been tight to fit last time round and the engine guy informed me he had machined the cam journals down to make it fit which thing had not made me happy at the time. Since I don't have a cam bearing install tool and had not yet realised the engine guy himself was responsible for the hand grenade I went back with the block and new cam bearings to make them fit. He offered to machine down my nice new comp cam and I promptly told him I wanted the bearings fitted and shaved to suit if the cam was tight. When he gave me the block back with cam bearings fitted he assured me the cam was a nice loose fit - which turned out to be absolutely correct if you didn't bother to push it all the way home at which point it nipped up. :evil: :evil: Had to pop out the rear welsh plug and spend a large chunk of an evening nervously and carefully shaving the rear cam bearing with a Stanley knife blade...

So I had the crank, rods, and pistons all zipped up when cyclone Marcia hit. Short video out my front window below. So with the day off work I degreed the cam and was then without power for the next week. Living without power takes sooooooo much more time just to accomplish the basics! :lol: I got power again yesterday afternoon so the head is ready to be torqued down hopefully tonight and on towards engine reinstall over the weekend.

Wow i hope you got your mains line honed the right way this time to prevent crank seizure i hope this time will be just as expected!
