Dropped off Torque Convertor to specialist to have it stall converted. My aim was to have the auto back off until boost begins to really kick in say 2300rpm. He opened it while I waited & suggested he fabricate it to kick in @ approx 2500rpm. This way I have a window between 2300-3000rpm that should see good results. Difficult to get my head around exactly how this works. Although, I better understand the theory behind stall convertors now.
I'm hoping this will allow the slow auto to comply better with boost, especially due to LPG fueling the thing.

I am very interested in how much you are been charged but the Auto specialist to pull apart the box and have it stall converted. While it is open is he looking at whether its been strengthened much?

I'm just getting the convertor stall done. The auto is still in car. Seller said it was strengthened but I only have receipt for sale of box to him. It had the spline & tailshaft housing replaced. That's all I know I'm afraid. I noticed when I shifted from park to drive, it took a few too many seconds. I read though that using incorrect oil effects gear engadgement. Hope Merc oil fixes that problem but I'll get it serviced once engine is sorted & car is drivable. Oh, cost! Not cheap sorry to say. $500 for mod I feel it is a good move though considering power train set up. Btw, how's it up there? Most of my family are up there. QLD's my old haunt lol. Spent most of my life in Brissie & 4 years in GC

Hey Guys. Work on the 300 has been mostly stagnant up til' now It took 3 engines before I got a replacement with decent, even compression. I am very reluctantly going with this 2nd hand engine as is (no re-build @ this point) as I just need car up & running & only to do short drives. If a rebuild is needed later. At least LPG/Turbo/IC/exhaust system set up will be all done & out of the way
Today I will be talking to workshop boss to finalise an ETA on dropping car off to him. At the moment I have the trans in getting a thorough check over by Merc specialist whilst car is still in my garage. I have removed cracked rear screen & there is next to no rust on the screen lip. Just a tiny bit needing only a grind & putty. There is no rust anywhere I have found after lifting carpets & checked boot Car is original red but looks as if it has had new boot lid & perhaps quarter panels replaced hence the re-spray. Unless it is normal to have dark-grey primer only on underside of boot & lid? Progress: I have stripped back all lacquered timber interior parts & painted them with red duco touch up. Spent ages & used primer, paint & clear. Came up surprisingly well. I had to break up the total black leather/vinyl look the interior had. Way too much stark black Turbo has been dropped off to workshop all rebuilt & ready to go This was done by an old-timer who knows his stuff & highly recommended Just a rehash of work to be done: a) Complete re-rout of Turbo set up which includes separate oil filter, high/low boost switch (mainly to lessen stress on engine when driving under normal conditions), full custom steampipe exhaust manifold to be made from scratch including an external wastegait to replace the rod-type & full 3" mandrel bend exhaust system right through from turbo flange to tail (nothing kept) b) Inlet manifold modified to better fit mixer c) Refurbish aluminium intercooler piping d) Complete rebuild of LPG routing. Twin Evaporators (convertors) with primer e) Dynotune .....and anything else that is needed to get it running reliably? If I get 300rwhp out of it. I'll be happy with that

Bad news back from transmission specialist. She's stuffed Needs a rebuild @ $1800. Woulda been more if I hadn't already had torque convertor worked on.
So need to consider long & hard my plans & options

Try finding a local box with low miles....should be $500-700 maybe less if you score a deal. I know finding used parts can be a bit harder over there.

Yep. Took me 3 engines to find one with good compression. My only concern is getting a trans well maintained so it will be strong & reliable

Well I've decided to get the box rebuilt & am getting a shift kit also for extra 200. This way I get a rock solid platform to work with from scratch. A 2nd hand trans doesn't seem a viable option when you need to purchase it then hope it checks out fine. Too bad if it doesn't.
Box will be ready by next Tuesday. Spoke also with LPG workshop & boss is checking over the latest engine properly to see if it has any mileage issues. Failing a thumbs up engine will be stripped down & rebuilt. Perhaps using the forgies from te orig' buggered engine car cam with. Should know by next week regardless. Then I can get the car out of the garage & over to workshop

Decision made! Rebuilding the M103 engine & seeing whether the forgies from buggered engine are worth using?
Here's to the money pit

PROGRESS!!!!!!!!
Have today off (miracle lately for the slave hehe) Spoke to Abdul (Merc spares). After waiting yet again for entire week with no return call or engine. Demanded he tell me whether or not he has an engine. NOW! He said he has a running car come in. Well. Better than en engine sitting in the yard out of some crapper 6 months ago! Demanded he do a compression test. NOW! Reminding him it will only be done by my mechanic soon as he gets it! He said OK! So, then he said he'ss ring my @ lunchtime & let me know figures. I said you better as I'm wearing thin with the patience lesson SO. Here's hoping on a star! A German star haha If I can land an engine with good compression. At least the bores will be good to rebuild. I'm not settling for risk of buggered bores & have to buy new (expensive) pistons. Besides. Then I can use the forgies if they are standard bore size? At least an option Eve though my mechanic will do a comp' test himself. Still a chance that everything will be in better maintained condition & a good, solid platform to work from. I also can get genuine parts heavily discounted from a Merc spares retailer that provides discount to forum members. Here in Aussieland. Canberra. Even found their actual website Forum Here's hoping.....hoping......hoping

Just got off phone to Merc Spares here in Melbourne. No go. Compression on 3rd engine was a pathetic 130 on all......so, will be dropping the 2 engines back to spares yard for a refund. Here I go again. At least I'll have my money back from this horrid spares dealer. Never to contact him again! Where I go from here who knows? I may even shelve the project indefinitely until I find a solid engine to use. May even look @ a possible upgrade? Just need time out consider options This has already been one hellova ride lol
