Like I suspected, it is the exhaust not being completely closed causing boost issues. I reseated and clamped everything, and I can make around 3psi. Yes Brad, v-bands would be ideal. The issue is, there's no space to put v-bands how I have the exhaust now. I want the piece that runs under the oil to be completely removable, for removability and space reasons, just in case. I'm going to start looking for another set of cheap headers to chop up and combine to add a v-band, see picture for what I'm trying to do. On another note, I have a piece of "welders felt" between my turbo mount and the fender. It's not very thick, and does not seem like it would do much, but it is working pretty well to absorb and dissipate the heat. I can touch directly on the other side of the fender right after a 15 minute drive without it severely burning me. It's warm, but not burning. I'm going to throw a second piece between and pick up some ceramic washers like other suggested.

https://i.imgur.com/lmqt4nR.jpeg oh dear, every other year i have to swap stock control arms for MOT. this time i fck it up, threaded nut went loose inside body from that bolt, anyone had to cut open body from inside to weld nut back in? and oil leak is still present

I am resurrecting this thread. Attached is the picture of the '73 240z in May 2013. Today after maybe 60k miles, the car still looks the same engine is pulling harder than ever, but we need a new Transmission and Rear end. After consulting with my son, I believe we are going to go the Subaru R180 LSD route for the rear end. For the transmission, we are planning to go to the CD009 or the 240SX FS5W71C depending on what we can find.

Still Available everyone!

@calZ I saw them on the Big Willow schedule and was curious who they were. I will look into them, thanks. Season is over anyhoooo. Back in the 90's at either track already, and I don't have the right gear for that weather. Prob be back at the track in Nov. Should have the 3.1L installed in a month or so.

Take it to a muffler shop and have them install two v-band clamps...

Lucky Dog would probably be a good organization for your car. Much more fun/$ than SCCA or the like anyway.

Also just for openness, this is my current budget states. Intake an exhaust manifolds are en route. A had a lofty soft goal of doing the swap for $4k or less. Still unlikely. But not impossible.

Most likely thing to be leaking is the wastegate if it is a cheapo one. Next thing would be to check the blow off valve, normally they are springed at 6psi by default. Depending on what kind of muffling your doing, you should be able to hear the turbo spooling up and screaming.

Hi all! Sorry for being MIA past two months. I changed jobs, traveled overseas, and general parenting obligations. @JMortensen I tried it for the first time at my local race equip shop! Need to get a copy on my PC with the Logitech wheel. Not as fancy as the setup they have at the shop, but all I’m trying to do is learn the track. Great recommendation. @clarkspeed appreciate all the feedback as always! @tube80z electronic brake bias didn’t even occur to me, but in hindsight it sounds spot on. Can use transducers with feedback to set-up pre-determined increments. Brilliant. Way beyond my skill or budget but i enjoy learning about the possibilities. updates: - work on air dam is almost complete. Widened to account for the additional track, stiffened, and injected PU foam In to the cavity created to stiffen and dampen. Almost ready for paint. - added AL cladding between the air dam and the rad support to eliminate air blow-by past the rad. Made a significant different in cooling. Will eventually add a wiper on the upper rad support to block air from going over, between the rad and the hood. - added a small electric 12” rad fan to manage overheating at idle. - PIAA lightweight motorcycle headlights installed. -fixed my camber issue in the rear. Moved-out the shock adjustment nob a little more than an inch to gain-back 4 degrees of camber. Rear now sitting at -3 deg. Still need to correct the front, although it’s not nearly as bad. Next up: swapping-in the race engine (3.1L). Looking forward to ditching the SU’s for some Haltech. Unlikely I will find a wheel-to-wheel class I can race with EFI on an L-series, but I’m simply tired of having everything smell like gas (including my hands, clothes, and even my living room).

Spent some of my lunch break today in the garage. Front engine mount (now front, RWD orientation): 2.8 lbs Driver's side engine mount bracket: 2 lbs Cylinder head rear coolant bypass (plus a solenoid I likely need to put back on at some point): 2.9 lbs Power Steering Pump bracket: 1.1 lbs (boy did I think that was going to be heavier since it looked like a chunk of iron)

Not too much to report at the moment. I’ve been battling electrical problems from the leftover stock harness, slowly replacing things. Did the ZCarDepot alternator upgrade because my stock wiring stopped charging due to corrosion. I can’t seem to make more than 1-2.5psi of boost. I’m going to retighten all of my intercooler piping and make sure my wastegate is working correctly. currently running an ebay special, 8 psi spring, no boost controller. I’m assuming it’s my pre turbo exhaust piping that’s leaking. I made the piping that runs under the oil pan removable, so there’s just exhaust band clamps connecting the two ends. It’s probably leaking around those, but I’m surprised I’m not making a little more. Attached is some test drives after rewriting my charge circuit, I love the way these cars sound.

Has anyone replaced their clutch master and the stock washer bottle wouldn't fit back in? What bottle did you end up using?

Since the reply button/box is MIA in the general engine/trans weight thread, I figured I'd just start a new topic and let an admin move the post if they wanted. I recently picked up a K24A2. It's an early TSX engine with a RBB-2 head, not the later TSX K24A2. I picked up crane scale that's (in my opinion) accurate enough for what we're working with. It has a limit of 660lbs and is supposed to be accurate +/- 0.1%. I started with the engine as delivered and pulled off parts at a time cataloging the weights as I went. My "linkage" weight was 0.31lbs, but I still tared it out. The engine as it sits in our starting point has known to be REMOVED: exhaust manifold, up pipe post throttle to air box, exhaust side engine mount (is there one?) The engine as it sits in our start point still HAS: Flex plate (auto trans car), AC/PS, Alt, Water Pump, intake manifold, DBW Throttle, Wiring Harness, Starter, and Oil (yes, came wet). It didn't gush any coolant, but considering it had oil I'm sure it would probably leak some coolant if I tipped it on an engine stand. First for removal was the power steering pump (and belt): That puts the PS pump at 6.4 lbs Next was the AC Compressor: That puts the AC compressor at a chunky 13.7 lbs Next was the tensioner: Puts the tensioner at 2.4 lbs Next was the wiring harness: Puts the wiring at 5.5lbs Next up was the alternator: Puts the alternator at 12.3 lbs Next up was a bunch of rubber hoses (vacuum and coolant) that were basically just in the way. Figured I'd include them as a step as to not throw off the weight of the next part: Puts us around 0.9lbs in hoses Next up was the DBW throttle (bolts were put back onto the intake manifold, this is just the dbw throttle): Puts us at 2.9lbs for the throttle body Next up was the "upper" intake (which I find ironic since it's physically lower) manifold half: Puts us a 6.8lbs for the upper intake manifold Next up is the starter (and some wiring attached that goes from the alternator and starter to the main fuse/relay section of the chassis wiring I guess): Puts us at 8.2 lbs for starter and wiring Next up is fuel rail and injectors: Puts us at 1.1 lbs for injectors and wiring (one tip stayed in the manifold, sorry. probably not much weight there) Next up was the lower intake manifold: Puts us at 9lbs for the lower intake manifold Next up is the oil still in the pan: Puts us at 6.2 lbs of oil I removed, which equates to around 3.4 quarts, so since these are generally around a 5-5.5 quart engine you could add another 5lbs to the initial wet weight to make it more accurate for a full wet weight. So what's still on the engine: Flex Plate Front engine mount Intake side engine Mount There's a bracket for the PS I haven't removed Water Pump Thermostat Housing Rear head coolant block Various Sensors/Solenoids (VTEC, VTC and more for example) Coils Spark Plugs Balancer A few random brackets There's probably another 5lbs of stuff from above that has yet to come off that is unlikely to go back on, though not everything that's going back on I can guarantee will be lighter than the OEM parts that came off. As such I'll likely weight again once it's ready to run. And thus there you go. What does a K24 weight? Somewhere between 240 and 320 based upon what the hell you're talking about.

Posting in the definitive engine weights thread shortly....

Looking for a kit for a rx5 turbo wansja@gmail.com

height is equal of L6 genuine fits well under the hood because my engine is lowered with dry sump, same for the OHC No inspection , the block is L28, that's all

1981. Manual Air.

What year? Manual or Auto Air?

That's what I thought. Gotta pay closer attention!

Not since Christmas lol

Evening I have just sprayed the first layer of Epoxi paint and that feels good as it feels that i'm moving forward. I need to buy a new spray gun as the nozzle is to small and there are no bigger to get(cheap one for fillers and epoxi so no harm). When the new one arrives it's time for some filler.

Thx, that great info. what do you think on tire setting with 15x 8 0 offset?

When I turn my fan switch on the aircon will commence no matter what the setting. I.e hot or cold -aircon on or just normal vent setting. Aircon System is working fine apart from this.
