Racing engine build

I meant the aftermarket one, goes on pulley, or balanced cranks i see sell for around $200

 

which im pretty sure is built into the crank pully right?

 

Ka24de is my opinion, dont listen to rumors, they rev fine, if u wanna live at high rpms just get a harmonic balancer

KA's do vibrate, you just may not feel it. The insides tear themselves apart and they can break cranks. The full race KA's use good dampers to stay alive, like one from Fluidampr. But that's a whole can of worms as all the pulleys must be custom fabbed to fit.

The charger is at my uncles. I can't sell. I like it too much. The thing is not streetable at all and the engine smokes like a bitch now. And I'm not about to say what I want to do with my car. I'm looking for something fun to do and something different.

 

So ka. Is it worth finding a 91-98 ka or just any? And what gave the 91-98 ka a few extra horse power?

Is this the yellow datsun that keeps up with the datsloco crowd on the fun runs? Lol i hear good stories, props

 

Depending on budget u can probably get a ka barb'd and pass smog and all

Yep this is Shelby the misfit. Runs hard and loses it in the corners but since I drive it in the hills all the time I got used to it sliding a little.

I'd say KA-T

Lz's are great sounding and great to look at, but more money to make hp vs KA.

 

If you balance a KA and put a good damper like above on it, and put some nice light and strong rods and pistons in it, it'll turn 8000. Your not going to turn a hopped up stroker lz more than that anyway. Mine will turn 8000 but isn't Makin any power there.

 

My balanced lz with a z22 crank/ ATI super damper combo if definitely smoother at high rpm than the stock l20b.. when I balanced it, it was only off about 6 grams or so on each end which isn't that bad. On the other hand, the flywheel was out a ton.

'89-'90 S13 were KA24E (12 valve ) heavy block and crank girdle 225mm clutch

'90-'97 D21 were KA24E (12 valve ) 240mm clutch

 

'91-'94 S13 were KA24DE (16 valve) heavy block and crank girdle 225mm clutch

'95-'98 S14 were KA24DE (16 valve) heavy block and crank girdle 225mm clutch

'98 and up D21 were KA24DE (16 valve) heavy block 240mm clutch

 

The DE makes maybe 10 HP more than the E, probably the better breathing 4 valves per cylinder. Ten hp isn't near enough reason to run it over the other.

This is the best reason to make it your race car. When I raced in the 70's and 80's I used "race cars", not the cars I drove and depended on all the time. But it is obvious no one can tell you anything, so go ahead and fuck up your Datsun

Why would it do that??? If you spend so much time, and presumably like driving, why not fix this and keep up??? Lower the car, excessive over steer has causes that can be cured..... larger front (only) sway bar/ remove rear bar, stiffer front springs, firmer front shocks....

Stop calling it a 510 unless you really have a 510. It's an A10 so call it an A10.

 

So how does that engine run now after spinning the rod bearings and scoring the crank? Is this why the talk about a 'race engine'?

 

 

Actually Mike you and I were wrong. The bearings never spun. And the crank was smooth. It wasn't the bearing by the way.

 

I wasn't wrong I was only going by what you told me about your clearances. So you measured then incorrectly???

No they were out but. There weren't any marks and the hearings were intact. I made a rookie mistake on what the sound was. Now I'm going to tell you what it was. But flat all at back off and if I hear about it after this canby won't be very fun. Now like I told Mike. After it popped out of hear getting on the freeway it redlined. Not long but long enough to make a matalic metal on metal sound. I get home. I hear it coming from the top end. I check the valves clearance. All good. It was only when accelerating. I pull the wires one by one and #1 cylinder when disconnected made the sound stop. So I figured "must be the bearings or pin. I pulled the pan. Replaced the hearings. Started it up and it still clicked. Now I'm mad. I pulled the head pulled the crank pulled the Pistons. Take them to the machine shop. Got the crank ground down because the mains were out of spec. I got the head rebuilt and new valves because they were bad. Checked the Pistons. All good now right? Put it all together mad as hell because i just rebuilt the damn thing less then 5,000 miles ago. Not the head but the block. I put it it back in the car. Started it up. And still clicking. Louder. I said fuck it and drove it that way for a week

 

 

 

 

 

 

 

 

 

 

What was the clicking sound?

 

 

 

 

 

 

The fucking fastener for the flare tube that goes into the exhaust. Just every time it fired on 1 it would slide a little and make a ticking sound.

 

 

that fucker was rusted to the manifold when I got it. Now it comes loss?!

Must be a race car. I can tell by the fancy seats and the racing seat belt and shoulder harness set up

 

I put racing 3 in lap belt and 2 in wide shoulder harness in my truck. Not racing seats but larger than stock bucket seats. had to go with lap belt and harness to get my seats to go back far enough, stock retractor prevented them from moving back. So do I have a race truck now?

About those. I got rear ended and it broke my seat so i needed new one. Since I had the money at the time and I'm always driving in the hills figured it would be good to put a harness.
