Uber Deaf One Posted October 20, 2011 Report Share Posted October 20, 2011 Hi guys. We finally got the KA 510 on the road last week... been dialing it in and working out some issues. It's a dual cam KA, freshly rebuilt, 2.5" straight through exhaust with a Magnaflow muffler, and a custom intake which is the same length as stock.... no other mods. Also running a 3.70 Subaru LSD and some cheap offbrand 195/50/15 tires. Rear alignment is -1.3 degrees and 1/16" toe in. I'm not really sure how fast this thing should be, but it seems like I should be able to easily spin the tires through at least first gear? That doesn't happen It feels quick, but does seem like it's down on power a little bit... I'm going to get some 0-60 numbers tomorrow. Anyone with KA 510s care to chime in? Are you able to spin the tires easily? Or does my 510 just have a lot of rear grip? It sure feels like it.... this thing grips the turns like nothing I've ever seen, and the rear end doesn't lose grip at all in the twisties. Quote Link to comment
510kevin Posted October 20, 2011 Report Share Posted October 20, 2011 My tired ka, with 3.90 open rearend punishes tires all the way through 3rd gear :) Quote Link to comment
INDY510 Posted October 20, 2011 Report Share Posted October 20, 2011 . You can drive a KA24DE with a backwards firing order ... and almost spin the tires in first ... . . . just sayin' .... :blink: Quote Link to comment
philcas1987 Posted October 20, 2011 Report Share Posted October 20, 2011 You're doing it wrong. That can take some abuse. Worn out single cam can spin through third Quote Link to comment
Uber Deaf One Posted October 20, 2011 Author Report Share Posted October 20, 2011 I figured.... now time to figure out wtf is wrong with this thing. :( Quote Link to comment
INDY510 Posted October 20, 2011 Report Share Posted October 20, 2011 I figured.... now time to figure out wtf is wrong with this thing. :( Check the firing order ...... .. sounds like you might have a dead spark plug Quote Link to comment
Uber Deaf One Posted October 20, 2011 Author Report Share Posted October 20, 2011 We checked the timing the other day and it's about 5 degrees out of spec (advanced) but we're still running the distributor kind of in the middle of its adjustment. If we retard it anymore, the car backfires and pops. If we advance it more the car runs really hot. The weird thing is this thing runs great, very smooth, just seems down on power a bit. Will check the plugs tomorrow... Quote Link to comment
Creepy Cruiser Posted October 20, 2011 Report Share Posted October 20, 2011 My tired ka, with 3.90 open rearend punishes tires all the way through 3rd gear :) X2 Mine with a low mile dual cam and great great tires, has a tough time keeping any sort of traction at all, lol. Quote Link to comment
Uber Deaf One Posted October 20, 2011 Author Report Share Posted October 20, 2011 I weighed the car today.. 2040 lbs. And it'll do 6 second 0-60 mph runs... does that sound about right or should it be faster? Quote Link to comment
bonvo Posted October 27, 2011 Report Share Posted October 27, 2011 sure its wired right Quote Link to comment
dennis Posted October 27, 2011 Report Share Posted October 27, 2011 I weighed the car today.. 2040 lbs. And it'll do 6 second 0-60 mph runs... does that sound about right or should it be faster? Depends on the driver 1 Quote Link to comment
CCAT Racing Posted October 28, 2011 Report Share Posted October 28, 2011 Depends on the driver Yeah, that helps him... :rolleyes: I think he is asking if that is a fair # with a stock engine/clutch @ 2040 Lbs... You guys would know best what it should be performance wise. A lot are saying it should spin the tires no problem just flooring it! Ours does not! It hooks up and goes! It seems to NOT want to spin the tires (hence why Uber is trying to figure out if times are in check). From a dead stop it pulls hard to 6500+ all the way to top speed! The suspension is set up with equal spring rate, good traction shocks, and alignment dialed in by my buddy at the alignment shop to our specs. Camber -2.5 Front, -1.5 Rear, 1/16" toe in Front. 1/8" toe in Rear, 2.5 deg Caster Front. It beat my wifes 05 GLI 1.8T 180 hp seemingly easy! Although she wants a re-match with her driving the GLI! LOL Our best estimate averaging a Smart phone app, and a G-Tech Meter we come up with about 170 hp at the rear wheels, 0-60 6 sec or less, 40-60 2 sec... Anyone have input? We are going to get some vids up soon of it running and driving, but it runs GREAT driving it! Quote Link to comment
INDY510 Posted October 28, 2011 Report Share Posted October 28, 2011 Yeah, that helps him... :rolleyes: No seriously ... . . if a KA24DE can't spin the tires through thrird gear you are doing something wrong, , , , or you are running on 3 cylinders .... becuase it will still drive fast with only 2 spark plug wires ...... :blink: Quote Link to comment
DRIVEN Posted October 28, 2011 Report Share Posted October 28, 2011 You said it's freshly rebuilt. Are you positive the cam timing is correct? They can still be smooth and run ok but be down on power. I've been a tooth off on T-belt replacements on other cars before. It had similar symptoms. Quote Link to comment
DRIVEN Posted October 28, 2011 Report Share Posted October 28, 2011 ...and for a reference, while my 510 doesn't have a KA, it's still a 2.4 4cyl with similar advertised power output. Traction can be an issue. On wet pavement I need to be really careful past 1/3 throttle. Maybe you're down on power - maybe you just have better tires than the rest of us :D . Quote Link to comment
Uber Deaf One Posted October 29, 2011 Author Report Share Posted October 29, 2011 Can you guys get some videos of your KA 510s spinning through 3rd gear? There doesn't seem to be any videos on the internet of KA 510s, or even 510s in general... We can get our 510 to spin the tires through 1st 2nd and 3rd if we dump the clutch at full revs.... but just letting the clutch out and nailing the throttle in first gear, it hooks up and goes. Also do any of you guys have adjustable crossmembers? I know if you have lowered 510s with the stock rear crossmember you're at like 3 degrees of camber which will obviously help the tires spin.... we slotted ours and have only -1.5 degrees of camber in the rear. We checked the injectors today and they are good, no leaks, good spray pattern. We can't accurately check the timing with a light because we can't get the idle low enough. the IACV is adjusted all the way in and it's still idling at 900 rpm. However we can adjust the distributor to where if we go too far advanced about 3/4 of the way it starts pinging, and if we go to the other end of the scale it has no power and starts backfiring. The timing has to be damn close... we're out of ideas. Tomorrow we're going to check the TPS adjustment, compression was checked when we first got the car earlier this year and it was solid. We'll do another test tomorrow.... At this point we're pretty much convinced this is how it should be, and we need to see a KA 510 video or see one in person to be convinced otherwise... :unsure: The 0-60 mph and 1/4 mile numbers seem to make sense, they may not be 100% accurate but they have to be close seeing as we did many runs. I'm trying to get my dad to race me in his '09 Mazdaspeed 3 but he's scared.............. that would kinda help see how well this 510 is running :P Quote Link to comment
H5WAGON Posted October 29, 2011 Report Share Posted October 29, 2011 Video of your car? Are you running the right computer? Quote Link to comment
jesusno2 Posted October 29, 2011 Report Share Posted October 29, 2011 My ka wagon will hardly spin the tires, but i have a ladder bar setup and a limited slip It will actually push the front tires. Quote Link to comment
Uber Deaf One Posted October 29, 2011 Author Report Share Posted October 29, 2011 That looks and sounds a lot like mine What differential is that? Quote Link to comment
jesusno2 Posted October 30, 2011 Report Share Posted October 30, 2011 H-190 with a LSD. I KA isnt a rocket of a engine as many claim that it is. I describe it as the perfect power for a 510. Not to much and not to little. Quote Link to comment
VintageRice Posted October 30, 2011 Report Share Posted October 30, 2011 My ka wagon will hardly spin the tires, but i have a ladder bar setup and a limited slip It will actually push the front tires. http://www.youtube.com/watch?v=By_T9Q9uGW0 So whats faster, your WRX or your 510 ?? I got a ride in my buddies 2007 WRX and its scoots. I wonder if my mildly build/carbed KA will come close in my 510. Quote Link to comment

yellowdatsun Posted October 30, 2011 Report Share Posted October 30, 2011 "Should it be faster than 6 seconds zero to 60?" Really?? How fast are you expecting a stock 2.4 liter to be? It's not a Ferrari. Six seconds is really quick, and you should be very happy with that. "Burning the tires through 3rd gear" Sure, if you like beating the crap out of your drivetrain. I have a VG30 in my car, and it's fast, but it doesn't burn rubber through 3rd gear. But then again, I tend to be nice to my clutch. Quote Link to comment
Creepy Cruiser Posted October 30, 2011 Report Share Posted October 30, 2011 I would bet that a 510 with a stock KA in it would be a stock WRX. My dime with a mostly stock 96 KA (with a light weight flywheel and good clutch), is just slightly faster than my buddies mildly tuned 1st gen WRX. Quote Link to comment
