well as far as im aware, most tuners dont intentaly blow up engines. ive had one let go.turns out it was the third second hand piston that was slapped in the engine. (poped 2 times prior and a second hand piston and rings got thrown in...

from what you have said its a slapper with oe strength parts pushing 3x oe power.. you dont really have anyone to blame. was the tuner aware of cast pistons being used? either way. the bolt ons you have are capable of over powering the bottom end..

id be throwing some rods and pistons at it.

did you gap the rings yourself? or did the machine shop do that?

shop did it

yeah he knew they were cast pistons. said hees done heaps around 500-550rwhp. even 600rwhp hees done on one. although im not sure how the mahle pistons compare to standard nissan ones. he said theyd be ok but

I'm not a professional tuner, however I can tune my car the way I want it to run ie: economy off boost and power on boost or if I choose (but I don't) to shoot flames on every downshift. It "should" be a given that someone who tunes cars all day long wouldn't make a mistake like that. I know I wouldn't and I only tune mine and a couple of mates cars. No det here.

Pretty sure both tuners I have been to made me sign a disclaimer before they would tune my car, saying that I understood and accepted there were risks in putting my car on the dyno and they would not be held responsible if anything went wrong.

Joe, you're on an Internet forum, how do you expect us to give you an explanation??

I cant disassemble your engine from here and measure it with a micrometer.

Have you even pulled it yet?

well youve given the diagnosis its all my fault. yous have gotta know what from.

Mate without giving you shit about it I would say read a stack of books about professional engine building and (almost) memorize them and thoroughly understand them. Hey at least it ran right?! So you have a basic foundation of knowledge there. Don't stop learning now, we learn from our own, and others mistakes. It takes years to gain the skills to work on cars properly. I'm 30 and pulled my first stromberg carby apart when I was ten. I'm still learning. I would say, pay to get it built next time and then you'll have the car/engine you that will last too. In the mean time get reading those text books or get a mechanic apprenticeship.

    • This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.
    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
