Thank you. Not normally, but they are close. With that said, the block deck and head have not been milled. Still, the factory head gasket is nearly .060" thick, so that helps.

I modify the pickup to fit within the stock pan. With that said, the inside of the pan is modified slightly, but there's no need to deepen the pan.

The 2.3 head will directly bolt onto the 2.4 block with 2.3 head gasket, intake manifold and exhaust manifold. You can run the small lifters with the 2.3 springs. The HO cams will fit the small lifters if you clearance the cam housing. The main issue is you can't use the 2.3 power steering system with the 2.4 housing. The easy answer is to use the 1995 2.3 cams in the 2.4 housings. They're a direct fit and a stronger profile than the stock 2.4 cams. They compliment the 2.3 head as well. After that, you'll need a tune as the 2.3 head raises compression to between 11:1 and 11.5:1 (depending on what stock pistons you have.

Copy. I was looking for the magical '95 transition cams for years but cant find them. Am building a historical "what if" gm had made the turbocharged 2.3 and/or a cobalt ss predecessor. It was nice seeing ideas ive had for years and years on some of your videos. It was easier to get an ho engine then a 95 transition engine. Tune will be no problem. Already running off a custom built engine management system. Car is running coil on plug and has sequential fuel and spark. In addition to gaining the ability to read boost pressure, the old map sensor now serves as a atmospheric pressure sensor. All of the cars original functions guages/equipment still work. It doesnt even know its lost control of the engine. As for the powersteering, i was planning on taking measurements, then destroying the 2.4 intake cam for hex drive insert then cutting, drilling and pressing the hex drive insert into the ho cam to retain power steering. Car is a 1997 sunfire gt.

Thank you. They're getting harder to find. Wrecked cars are a good starting point as they had to be running in order to be wrecked. ;) Any LD9 with over 100k miles should have the timing chain replaced along with a new water pump. If it has over 150k, replace the oil pump as well. If I had to be honest, anything with over 150k should be rebuilt.

All torque wrenches have a variance. Plus or minus a certain percentage. If it clicks high, there's no way to tell. If it clicks low, it will be corrected on the second torque attempt. With that said, there is also a "break away " torque, which is the amount of torque needed to overcome the static friction of the fastener before it begins to move. Even a low torque click will mostly not have enough of a variance to overcome the break away torque, so the fastener in question must have been quite a bit under specified torque. Bolt stretch is only a consideration if they're over torqued. One could click the torque wrench a thousand times and if I stop on the click, it wouldn't effect the bolts torque or stretch, since it didn't move. Another thing to consider is this motor is for sale and I have a buyer who is watching these videos, so it's good for him to see that everything is double and even triple checked for accuracy. Thank you for your comment.

@@LD9user sir, theres no need to explain torque wrenches. i know how they work and i know how theyre tested and adjusted. my point is that you hit breakaway torque AND THEN keep turning it. not every part is *that* important or anything, but some parts matter more than others. you dont need to "check" the torque, just do it right the first time.

¡Gracias, amigo mío! Me alegro de que los videos sean útiles.

@@LD9user No dejes de hacer vídeos, son muy utiles. Felicitaciones

That's a really good tip. Recently, I found a local industrial supply place that sells the helicoils in different lengths. Started getting the long ones.

Ebay is a good source.

Back when I rebuilt mine there was more parts availability. (Although, one site I used stopped existing thankfully they didn't just take my money.) Even then rods were hard to find. But it would be nice if a manufacturer created a big parts list you could sort by dimensions so that you could find compatible parts easily even if it is not original.

There's a follow up video coming soon. Wait till you see that crank. Looks amazing.

@@LD9user So long as the machine shop can do it 100%, it's worth doing if perfection is desired. Many times a good low mile, well maintained engine will not need crank work other than a light polish. And many more times, a machine shop that isn't 100% competent can make one worse off than it arrived.

Should be a parts diagram online.

@@LD9user when I ordered the intake cam cover gaskets, it came with an extra circular ring, Im trying to figure where that goes.

@@LD9user part 01989866 seems to be for camshaft position sensor(10456615)... so what did i scrape out of the pump kit(ac delco)? between 12578146 and 26091879 there is no other gasket... I probably messed up?

Yes. 16 LB-FT is 192 LB-IN. The threads tend to pull out of the head with the higher torque applied.

Recommend weight is 5w30. However, we're pushing these motors well beyond what a typical street motor would encounter. Turning 5500 to 7000+ lap after lap is way too much for a typical 5w30.

Thank you for the comment.What type of tensioner are you running? There have been a few different designs.

@@LD9user the second design like you show in the video. Under future investigation I realized I have the wrong timing chain and possibly the wrong cam sprockets. Rock auto has the correct ones for 92 grand am on the way so hopefully that fixes my problem!

Lowes spring numbers: 430977 422427 One spring is inserted within the other forming a double spring.

That's a good tip. This motor has the 2.3 oil pump swap.

No. This motor has the balance shaft delete/oil pump swap.

That is common. Nowadays, I simply torque the housings to 15 ft lbs.

Absolutely. Things are a little crazy around here at the moment. Will be uploading a video soon. Ring that bell! 😀

@@LD9user will do and do u have a Facebook or anything so maybe we can chat about motor stuff some time I race a toyota camry 2az fe motor just wanted to pick ur brain if u have any knowledge on that motor

You'd need to have the crankshaft turned undersized for the .25mm or the .50mm bearings to fit. It's usually not too expensive and you would end up with journals that are perfectly sized.

@LD9user 😢 Car still runs, but haven't driven it since. My only mode of transpo. Lost job as result (live in farm country). Spent every last available $ addressing timing system and top end. As "cheap" as it may be, it's still beyond my means, leaving me still stranded.

Thank you for the comment. I've done it both ways and obtained equal results. You could go forward and reverse...I feel it's a personal preference.

@@LD9user Ok. Just wanted to get your take on it.

That's possible, but that was checked.

Sí. Gran parte del trabajo se centra en darme la mejor oportunidad de terminar la carrera. La mayoría de los enduros son de 100 vueltas.

That is true. However, both bearing manufacturers are premier quality products within the industry, which leaves the oil as the main variable. I believe Castrol would work really well for a hot street car that might run a drag race on the weekends, and do so at a reasonable cost. Circle track racing is quite a different environment, however. The motors really take a beating.

Thank you for the comment. My understanding is Amsoil makes some amazing products. Can't really complain about the performance if the GP-1 oil though. With that said, oil companies are sometimes bought out (like what happened to Brad Penn) and formulations get changed. If that happens, I'd put Amsoil at the top of my go-to list.

They're held at multiple locations by me. We're going to find someplace in the spring. The onboard Gopro should be a gas.

I may have something here. Please email me a picture at mpclass3@yahoo.com.

Thank you! There's still a lot of work to do to make it reliable for an enduro, but I'm feeling good about everything so far.
