Spencer Posted August 3, 2022 Share Posted August 3, 2022 So missed it but you have some china H beam rods? the ebay ones? CP make pistons? like $1000? is that the path to spin this to 9k later once this one throws a leg? Said it like three times but I didnt chuck any in the engine $ it got closed, happy to chuck in 1/10th of piston costs for the best project on oldschool. 7 Quote Link to comment Share on other sites More sharing options...

Muncie Posted August 3, 2022 Share Posted August 3, 2022 Need some dry break connectors and plugs for the loom so he can do rapid roadside engine swaps. Might need a pog style crane bolted to the roof to aid engine ejection....... 2 Quote Link to comment Share on other sites More sharing options...

Ahhh not too long, maybe 3-4 hours of mucking around. It's definitely the easiest FWD car I've worked on. The bulk of the work in this case though is other stuff. Need to strip all of the accessories off new motor, swap the head, swap the sump, fit the flywheel and so on. As well as pull all that stuff off the 2NZ. I've just got to swap the sump over then seal up the timing chain cover, then this motor is nearly ready to go in. Oh, and drill the block haha. Will tap a thread into it this time though. I checked the cam timing, and it looked correct which is a little concerning. As it's got me wondering if something else is wrong with the head. I guess I should done a compression test before pulling it out. I had a second look at the head and couldnt see any dislodged valve retainers, or slightly tweaked valves or anything like that. But if necessary I can just put the new 1NZ head on, it's just a bit of a pain swapping the valve springs over and redoing all of the clearances. I'm on a mission to get this back in and running before the weekend, as I have to leave for a few days for a work trip after that. 10 Quote Link to comment Share on other sites More sharing options...

Yeah I've got a set of Maxspeeding rods, same brand KPR uses to spin his 4AGE to 10k rpm. However, yeah it needs the pistons to go with it. I'm definitely keen to build one with forged pistons as well, but not quite yet. One of the companies makes forged 1NZ pistons for a 75-77mm bore, and anything from 7:1 to 15:1 compression ratio custom order. For around $1000 a set. Boring it to 77mm would take it to about 1570cc. But all this means the car's off the road for much longer, and costs go up considerably. I'll be keen to order some once my life is back on track with house situation though. My big goal for the moment is get it all going with a standard block, get back to the dyno with the good exhaust and see what happens. 13 Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted August 3, 2022 Share Posted August 3, 2022 Once you get your "life back in order" (then tell me how its done) can you log the number of 9k pulls this engine does? When this one goes Bang! You'll have an idea how long one lasts. But once your shit is sorted, time for Round two of crowd funding. I'd say sub one month to raise enough coin for a third engine, and a set of forgies. Then you can build it up while waiting for this engine to scatter its gizzards all over the road. This thread is better value than Netflix. 6 1 Quote Link to comment Share on other sites More sharing options...
Popular Post Roman Posted August 3, 2022 Author Popular Post Share Posted August 3, 2022 I think there's a way I could achieve this. There's two ways that my ECU can do logging. You can plug in the laptop, and it records everything to that. Or you can record to the very limited onboard memory when certain conditions are met. I never really use the onboard logging, apart from when I want to look at something with a bit more resolution (as it's 100hz vs 40hz) Since the amount of memory is small, you also need to economize which values you want to record. However, I could setup a trigger condition so that it just just records engine rpm only, at say 1hz resolution. Every time the motor goes over say 8000rpm. Then when it blows up I'll have a log of hours spent in the danger zone... I'll be honest though, when that last motor blew it rattled me a bit. I felt lucky not to have started a fire or skidded on the oil or something. (or oil filter...) It would give me the shits to do that at a track day at higher speed. Longer term the stronger pistons and rods will be a necessity for safety's sake more than anything, I think. One interesting thing that I've noticed since I've blown holes in my old block. Because the factory pistons and rods are so light, (I guess?) there's only one counterweight per cylinder. Also, here is a shitty time lapse video with some annoying generic music, of pulling a big bunch of junk off the motor. 15 1 Quote Link to comment Share on other sites More sharing options...

kpr Posted August 4, 2022 Share Posted August 4, 2022 Unsure how often it reports a "rpm limit" I shall do some testing next time its running and report back. in the meantime here is a more recent one /spam 4 Quote Link to comment Share on other sites More sharing options...
Roman Posted August 4, 2022 Author Share Posted August 4, 2022 Ahhh right! Well that makes life easy. I've never used that before. Just checking my current stats, I must have unkowingly reset it at some point. The numbers are too low for it to be all time numbers including Carina usage. 122 hours total runtime. I'll reset the stats for the new motor. A lot of these stats (like 150deg temp, or 12400rpm) are from things like a sensor being unplugged or trigger errors when first setting things up. 7 Quote Link to comment Share on other sites More sharing options...
BiTurbo228 Posted August 5, 2022 Share Posted August 5, 2022 On the crank front it's not wholly unusual to have 4 counterweights in 4-cylinders, especially as you say with light components. The main way I4 cranks bend is around the middle bearing. The other side of the first throw is balanced somewhat by the 2nd throw (and number 3 to number 4), which leaves a rocking couple between the 1-2 half and the 3-4 half as the crank wants to bend like a skipping rope through the middle. You get it a lot with inline 6 cranks, like the one in my AJ6 which is counterweighted on the outermost and innermost cylinders, missing out throws 2 and 5. High performance cranks like S54s or 4G63s tend to be fully counterweighted to sort rocking couples at the expense of greater inertia (which affects resonance), and compensate through making them super-stiff. For small engines with light components it doesn't seem like a major drawback. BMC A-Series will happily rev to 8500rpm with 4 counterweights and only 3 main bearings! 1 Quote Link to comment Share on other sites More sharing options...
