it’s an expensive engine to learn on is what he meant.
If brenton does all the measuring, and pre checks etc. the final assembly is the easy part.

Hi mate, sure here it is, yea look I appreciate what your saying, I was (am) nervous about tackling it myself also. But I spoke to IJ and he reckons to have a go, and when I dropped the parts down to Brenton we spoke about it, and he also said he thought I should. Its actually a big reason to put it on the engine dyno afterwards though, as any issues will show up then. I feel like its the one part of the car I haven’t really been involved in, at least this way I will only have myself to blame if anything goes wrong

WOW was that assembled in a Sand Pit?
Did you cut the filter open to have a look Gary?
Looks like it’s been in bypass more than once.
Could pcv running via un filtered air intake played apart? Could of got some debree in the oil

Posts: 5 777I said above, I took it down to Brenton Marusic on Saturday, he carefully looked at it all, heads, pistons, crank etc and he looked me in the eye and said and I quote “that is all caused by the tune 100%” No I haven’t cut open the oil filter yet. Cav there are literally thousands of race cars etc that dont run an air filter, they dont end up looking like that. Its done, it happened, I’m moving on.
Good thing you pulled it out for a look rather than leave it.
But yeah reckon most of it caused by tune first having it super rich glazing bores maybe even some extent washing the bearings too contaminating oil.
Heard of a few blokes popped headgaskets just to get their cars through epa/engineers.
Sucks bottom end couldn’t have gave got away with good hone & clean.

Posts: 5 777Yea exactly, that’s pretty much exactly the scenario Brenton described, makes sense. Poor engine really from day one being sold totally the wrong injectors didn’t help, all started there washng the bores and contamination the oil. I am really hesitant to talk tuners, I always try to focus on the future not the past, its done, I am comfortable I understand the failure mode.
But for sure I am very pleased I pulled it when I did, alot of the thanks for that need to go to IJ, I spoke to him at length to pick his brain once I saw what was going on and he was the one who pretty much said dont risk it. Lucky I did.
Its going to kick ass though hopefully in its new incarnation, cant wait.

Posts: 5 777Btw as a side issue, i started trying to change over the pics on this thread to Imgur, best part of an hour to do one page, and theres bloody 70+ of them fml.
Photobucket can go EAD!!!
Sadly that’s part of the hobby we love having to navigate through con artists & shoddy work just to end up fixing it ourselves.
Makes it much harder to hand over the cash when finally do find good tradies.

Posts: 5 777So true, do feel a bit like the main issues I have ever had are only when I hand it to someone else. But unfortunately I can’t tune, and tbh don’t really have the desire to learn.

Posts: 775hey Gary this most likely in the post some where but di you just get the motor with out intake and is that why the wrong injectors in there , dam I wish I could have the lsa motor but sunk cash into other bit of land instead

Posts: 5 777Yes it’s buried back there somewhere… Basically the Australian Jenvey distributor recommend Marelli IWP injectors. Problem is they are a great injector, but designed to be mounted at the top of the trumpet spraying in like in a racing Ducati. Consequently they have a very wide spray pattern. But on my intake it means the outside of the spray cone at lower rpm hits the inside wall of the intake runner and falls out of atomisation and doesn’t burn washing the bores. We discovered the issue during emmisions testing.

Posts: 5 777Dropped off the parts to Brenton at THR as he wanted the main caps etc for when he is boring it. Got a nice tour of the workshop, very cool. Didn’t realize along with the engine dyno, they do their own engine machining as well as restorations and chassis work, lots of cool are in there. Had a good look at the engine dyno room, also very cool from an engineering perspective. So machining process starts tomorrow, I think the plan is a light hone first to see what its like, then go from there. Everyone drops off 454 parts using the 911 ute dont they!!

Posts: 775Thanks for explaining the injectors and spray pattern makes more sense now , I tried to reply to that post but didn’t work
am I doing it wrong

am I doing it wrongNot sure mate, I have quoted you to make sure its working. But if you have issues let me know and i will see if Georgie can sort it out.
To give you an idea, the Marelli injector cone angle was 50 degrees, whereas the ID’s are like 10 degrees. A massive difference.
This is why its so important

Posts: 5 777Well gotta say I am less than impressed with the quality of how this thing was originally put together. Seems there’s evidence of fretting between the main caps and the block. There is only one cylinder that’s half decent. Good news is we should get away with a 5 thou hone, but will line bore the mains whilst we are at it make sure its perfect. Block has to be faced as well, he can feel the ridges with his fingers. I wont lie I am bit gobsmacked. Part of me is pissed off, the other is so glad I pulled it when I did.
Very ordinary to say the least. Does the engine not have a warrenty at all?

Posts: 5 777I really dont think so Cav, I bought it over 3 years ago, and so much has happened over that time. I think its really poor though, I mean how could the top of the block be that rough, nothing I have done or could do, could cause that. The heads have never been off. It just was never faced properly.
