Popular Post sheepers Posted April 20, 2024 Author Popular Post Posted April 20, 2024 Dipstick. I didn't have one with the engine parts and I had to move the location. The 7M Dipstick location is right where the 4M engine mount goes so I had to drill another hole in the block. No drama the boss is cast into the block, just had to drill it. Then I set about modifying a jz Dipstick tube to work. I drilled the hole to big for the jz tube so I had to weld it to build it up then machine it to size. I fluked the size and got it perfect, its a good tap in fit. I cut the stick to length and used the 4m in the crown to get the oil level marks right. Then I put the sump on, probably not for the final time but it's on. 28 Quote
Popular Post sheepers Posted April 20, 2024 Author Popular Post Posted April 20, 2024 Triggers for the ecu. I couldn't use the stock 5M dizzy because it sits exactly where number 1 throttle needs to be. So after a bit of indecision and fucking around I decided to run a crank angle sensor off the front pulley. I machined the inside of the pulley to an accurate size then I made a boss to press into the pulley. The pulley is cast so I can't weld anything to it. She's a fucking tight fit in the pulley so it ain't going no place. By pressing this hub into the inside is not affected by the rubber isolation layer which can cause erratic triggering. I'll laser cut a trigger wheel and use it to accurately drill 4 mounting holes. Then all I have to do is mount the sensor off the front of the motor somehow. 23 1 Quote
Popular Post sheepers Posted April 28, 2024 Author Popular Post Posted April 28, 2024 I've never really had a lot of luck restoring plastic parts. Usually ends up full of scratches or looking just as bad as it did bit with a shit paint job on them. This time however I'm pretty happy with the result. As is fucking Usually the story I was too useless to take a picture before I started. You'll just have to take my word for it being 40 odd years old and fucked, full of scratches and discolouration. Now it looks ace, I'm really happy with this. The 4 square millimeters of it you actually see will look amazing. 30 1 2 Quote
Popular Post sheepers Posted May 11, 2024 Author Popular Post Posted May 11, 2024 Crank and cam triggers done. Crank trigger is fairly self explanatory. Cam trigger was a bit more difficult. Is basically the eccentric cam that would have driven the fuel pump. I welded a lump on it and filed it up to make a tang. The sensor can reach the 40 odd mm to get a signal. I don't know how I'll time the engine because the lay shaft that this is on can go anywhere. That can be future sheepers problem. So the front cover and the sump is on for the final time. It's taken so much work to get to this point, what the fuck am I doing...... 35 Quote
Popular Post sheepers Posted May 26, 2024 Author Popular Post Posted May 26, 2024 Painted some more engine bits. Big woop. Also made a round object to put in a round hole. 22 Quote
Popular Post sheepers Posted June 16, 2024 Author Popular Post Posted June 16, 2024 Made a water pipe. Factory one is mild steel. And 40 years old so it's pretty fucked. Bought some 16mm bends and a T and made a new one. I think I'll stick another bracket on it then it's done. I have no idea what the water circuit is going to look like with the ITBs and whatnot but I'll figure that out as I go. 56 Quote

Popular Post sheepers Posted August 18, 2024 Author Popular Post Posted August 18, 2024 Cylinder head is on. What's it been? Like 2 years or something. Anywho to recap, 13 to 1 compression 1mm over sized stainless valves Custom valve springs with 80 pound seat pressure Approx 3mm higher lift/custom cams Ported head Probably some other shit. 41 1 Quote
Popular Post sheepers Posted August 31, 2024 Author Popular Post Posted August 31, 2024 Some engine got built today. I pre lubed the lifters and got all the air out of them. Assembled the cams and valve drive train. Chucked a few random parts on. Hilariously this engine has 5 temperature sensor locations. Like that's going to fucking help. Also I have some other cam covers on the way for it, these are just too keep the shit out. 39 Quote
Popular Post sheepers Posted September 16, 2024 Author Popular Post Posted September 16, 2024 I made a tool to to spin the oil pump shaft with the drill and got some oil pressure into the thing. Obviously the motor wasn't turning, just the oil pump. It got pressure up and went up to 60psi on the drill. Then it was like a relief valve opened and it dropped to 30psi after about 5 seconds. I turned the motor 180 degrees and tried it again and it did the same thing. No idea why it did that tbh but I'm going to get the whole motor spinning on the starter and see if it still does it. Then I guess I'll have to figure out why if it's still doing it with the whole thing turning. 14 Quote
sheepers Posted September 16, 2024 Author Posted September 16, 2024 it could be the bypass valve in the filter (Z9) opening becasue with the motor stopped there's not nearly as much flow? what do you think?? Quote

Popular Post sheepers Posted October 4, 2024 Author Popular Post Posted October 4, 2024 i have been fucking around with a manifold design. i have been looking at the EFI hardware stuff, mainly becasue it looks like it might work. be keen to hear what your thoughts are on the different options for generic throttles. the EFI hardware stuff can give me a throat spacing of 90mm which i think i can get to fit. we have a rapid prototype machine at work now so i can probably print myself a test manny to see how things might workout. anywho, here's wonderwall. 27 Quote
Popular Post sheepers Posted November 25, 2024 Author Popular Post Posted November 25, 2024 Printed this at work. It fits pretty well considering the sizing was a complete guess. I might angle the throttles up higher a bit? I need to guess what some of the clearances might be 30 Quote
Popular Post sheepers Posted December 4, 2024 Author Popular Post Posted December 4, 2024 Printed some throttles to get a better idea. It's pretty good, I'll guesstimate how it might work in the engine bay and take it from there. 27 Quote
Popular Post sheepers Posted December 4, 2024 Author Popular Post Posted December 4, 2024 hey, also it should be made very clear that i have no idea what I'm doing. I'm literally just doing whatever looks good, there is no science in anything here, diameter of the throttle? - fuck knows, whatever will kind of match up with the head and still be big so it looks cool. length of the runner? - 80ish mm because that the number that i pulled out of my arse. angle of the throttles in relation to the motor? - 15 degrees because i have no idea why. if there's something that seems fucky please speak up, like i say these is no science in this at all it should also be noted that this engine isn't really destined for great horsepowers, its a fucking 5m, if i wanted max powerz i wouldn't have started out with such a turd. any input would be appreciated, unless your a shitposting dickhead, then its not. 18 2 9 Quote
Popular Post sheepers Posted December 11, 2024 Author Popular Post Posted December 11, 2024 I bought a 5M-GX exhaust header kit. As it the style with this type of kit there is some assembly required. 26 9 Quote
