Yeah the bit your after is part of the oil pump. They usually stuck in there pretty good, not something that would just come out. hole maybe flogged out and may need to look into other options, if just falls out. rather than the factory part

If it were some kind of issue with the injector coil like you suspect. that could do all sorts of silly stuff with the dwell time. so no, or next to no fuel could have been coming out on idle. what was wrong with the xpurt injectors? Thought about running unmodified bosch injectors?

Run it up on dyno today, changes gears revving to 9700pm so looks like gearbox issue is fixed The new old engine has gained a touch of power (different headers). was laying down 152kw pretty consistently when tuning and playing with cam timing. was doing the runs at 90degs oil temp so could keep things consistent when setting cam timing. Then done a run with bit more heat in the oil, as they spit out a bit more power. 155kw with 100c oil green line is good engine. blue is the turd with vvti. red is a kinda stock engine with my good headers and exhaust. I ran though a few cam timing settings, to see what it would do with vvti (the above graph is done at 5deg inlet advance) Holding 150kw+ for 2000rpm will be amazing video of same thing

depends where the ecu is feed from also, quite common to get volt drop if wiring not up to it. likely find if measure at alternator, will be holding stable I'll try disconnect alternator next time have something on dyno

Good engine back in and running, think it has a little intake leak. but other than that all seems well so far, after sitting almost 2 years. Have only pushed it back onto dyno rollers and ran it through the gears. which seems good so far also. clutch feels pretty much the same, nana as. can take off in 3rd on dyno. Next need to set the cam timing (was using cam gears on turd, soo all screwed up) on dyno and probably do a little tuning. I haven't had current headers on this engine. they were good for a touch more power over the other ones on the turd. unsure what they will do on this engine. Then can see if the gearbox wants to play the game.

^ That's because it was a 16v back then. 20v not enough jam to break current one Will see how it goes. no big drama to swap to something else. was just the easiest and cheapest way to pull weight out of it. almost pulled trigger on one of these,but cheaped out. has sprung center single plate

^ this Probably not ideal. But if it changes gears, not worried if it doesn't last very long. considering the amount of use the car gets

New clutch plate showed up. actually fits. feels decent amount lighter, so should help the cause. Will have to go to a whole new flywheel and clutch combo to trim anymore weight out here

Turd engine is out Would have liked to run the vvti setup for awhile longer on this engine to prove reliability. But gearbox issues and time to keep things moving Gearbox issues being; it wont change gears at high rpm. which is rather annoying when engine pulls 10k, but can only rev it to 7 if want to grab another gear. Decided to throw some new parts in the t50 to attempt to make it better. Some parts are no longer available. but managed to get syncro's and selector sleeves and a few bearings. One of the parts no longer available is this bit, the dogs that sit on side of the gear. also happens to be pretty tired on most gears. I managed to pinch one out of my pile of parts, that was slightly better for 3rd gear. The other ones from my parts box (t40) were different design and were welded to the gears. so no go Angle grinder to the rescue. No idea how well its going to work, and probably should have set it up in lathe so angles were bang on. but cant be any worse than being blended like above. gave both 2nd and 4th bit of a zing like this. All back together. much easier to work on than a w box Also got one of these on the way. kinda winging it and hoping it will fit with stock style flywheel and pressure plate. as its from a orc clutch/flywheel combo. The sprung center in the current one seems fairly heavy. so this plate should cut down a bit of weight syncros have to deal with

someone doesn't like the metric system. but looks ballpark, long as there aren't any other compensation or 4d maps adding to it. All the stuff from the states is super expensive atm, prices gone up and bad exchange rate. Looked into any of the jap brands? quite a bit cheaper getting stuff from japan if there's an option worth considering

Vac tank with 1 way valve, and 3 port solenoid would be way to go

looks like should nicely fill that dip at 6k another run with those long bendy intake runners please

Was more meaning like in this picture rather than number 2. not the scratches but the textured look. should be able to look up and compare to some pictures what it means. this is one of the mains i assume? number 2 looks like something else again Either way it looks like it was knocking right up until failure, the way the piston is so clean in damaged areas. weather that was due to some previous damage. causing oil contamination in that cylinder. or a fuel/ignition advance issue is the question I'd do a roman dave milk bottle injector test. That will test the ecu, injectors, wiring at the same time. give the loom a good jiggle around in the process, see if any injectors play up. would work just as well / better than sending everything away to be tested Any chance we can get a screen cap of the ignition map?

Nar nothing like that on this engine. the throttles are cracked open for idle speed. which is a little more than usual due to cams. I could probably run an isc and shut the throttles completely. make sure the isc is locked out at high rpm. but rather avoid any extra stuff on this setup. also seems to be more something that happened to the box or engine thats in it atm. as wasn't as bad on the other engine. i dont recall having issues changing at 9k before, now about 7k is best it will do without waiting for revs to drop wayyy back.

so helpful haha. But yeh some tuning stuff is sure to help to a point. Swapping engines soon, so will throw the new parts in box at same time. maybe a combo of things is making it trash. kinda hoping the spigot bearing is screwed in the junker engine too.

yeah few places do them, but would rather try a j160 than spend 3k on close ratio gearset for t50. I did come across another issue related to the junk engine in it. It real sloppy on deceleration, due to poor ring seal. its like popping neutral on overrun compared to the good engine. So revs will be hanging longer than they should. Also looking into super light clutch/flywheel combo.

weird texture on the bearings can be signs of knock. i assume number 4 big end bearing is a pretty beaten up? what do all the others look like?

Yuck ^ Number would be up there if it logged how many liters of oil it used

Takumi still using it bro

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

The ecu stats on link is fun game, this is off my starlet a few years back

Its just a G4 ecu. The gear cut control looks pretty basic Pretty sure its a mechanical issue. as never once got it to change at high rpm. but yeh that would be a good setup to have, to take bit of human error out. Have some new parts on order to throw at it, hopefully will make it better

Possible has had some previous damage. and has been your misfire issue all along. if that hole was burning a bit of oil. which looks like it has been, would be more prone to knock. Which will have been what ended it for good, you'll probably find the ringlands just floating around in there when pull the pistons. you can get all fancy and egt every cylinder. but making sure isn't set on the edge of knock when tuned is the main thing. checking the plugs after few pulls is good idea also. Not saying it was a tuning issue. but also make sure you tuner is using knock detection and not just using ign map numbers that worked on another engine the same.

I tested it with a crappy supercheap compression tester awhile back before put the trd head gasket on it. 130 , 130, 100, 130. can only assume its worse now. with factory cams, no body home on 3 at idle. with the bigger cams idles like junk anyway so easy to ignore. end game is to build the long rod engine properly. with the head off the 150kw engine along with vvti. around atlantic 4age numbers but with a massive power band and reliable is the goal. looks doable at this stage turd will be coming out soon, and in the meantime will be putting 150kw engine back in. probably put a vvti setup on it also Too many bits of pistons and rings coming out the exhaust, might break my camera

Yeah found the same thing. looks like couple of them maybe the same was w/g box. but not much coming up for them either dog box way out of my budget. Think i'll throw some new oem parts at it if cant find anything else. I probably didn't put a new spigot bearing in the end of crank, when put the junk engine in. so probably a suspect worth looking at that could be causing some drag if its toast. It used to work fine with 9k limiter and bigger 212mm clutch. so thought another 1000rpm wouldn't be too much to ask.
