Z U L8R Posted February 12, 2008 Share Posted February 12, 2008 i sold my 280z and i'm in love with my 72 510. i have a ka24de in it at the moment. i have gsxr1000 itb's i plan on putting on it and making a plenum. but in the meantime i'm beefing up the suspension/drivetrain/brakes. my goal: 450-500rwhp my line of reasoning is that ka with 20 over pistons, rods, bearings, head gasket, arp studs (cams are a possibility but still indecisive) should be able to support that goal. and being oversized it should make the displacement comparable to an rb25....with that as my thought foundation. i will probably be going with a gt35r or a gt30/76r + nitrous (for the quicker spool to the 400 range then the extra shot for back up to reach my hp # goal. was just curious to hear from other ka-t people on what their set ups are with what kind of numbers they're making to give me an idea of what some been there done that options are, thx, Dave =] Quote Link to comment Share on other sites More sharing options...
mannyvig Posted February 12, 2008 Share Posted February 12, 2008 A guy from work here has a 98 240sx with a KA-T and Unreal suspension. It is a time attack car. He built it with CP pistons, Cometic hg, ARP everything, custom top mount manifold, GT30r and the full AEM EMS system. At 18-20lbs of boost it put down about 430 but was kept at 14lbs dyno tuned at 356hp at the wheels on a mustang dyno. I have driven this car and can attest to the fact that it is stupid fast even on the low boost. However, after much abuse the rods apparantly weakend. He was giving me a ride to an appointment I had and cruising at about 2800 rpm it died nothing loud though. We tore it apart and found the no.1 rod snapped and ripped through the girdle and block. This weekend we put the new motor together with the new Carillo rods and new CP pistons. This time it has a ported head though . It should be wicked fast for another 8 months before it breaks again. were gonna finish it up this weekend and have fun all next week.

Z U L8R Posted February 12, 2008 Author Share Posted February 12, 2008 lol i like how u said "it should be fast for another 8 months before i breaks again" = the story of my life >_< so far i've got 6 grand in the 510 walboro 255lph inline fuel pump, 1" front sway bar, rear quicker bar, 280z front suspension /w 4 piston toyota brakes, wilwood rear disc brakes, and old tired ass 240,000+ ka24de that i got from a friend for free front coil overs /w 225lb springs and camber/caster plates. i have a front strut bar off a 240sx, the bolt pattern is the same but i need to shorten the bar to make it work next on the list *rear coil overs 200lb springs /w 16 way adjustable dampening *300zx tt lsd (3.69 ratio) in the back and shortening the cv's *300zx na 5 speed tranny + uber driveshaft for it *9 second roll cage and possibly stitch welding the chassis up (i really don't wanna twist this chassis, it's too pretty lol) *sissy gas tank with a cheesy fuel pump so i don't run out of fuel when cornering.....(or doing wheelies ) that should take care of the suspension/brakes/drivetrain then after a couple sidework motor swaps *77 Rabbit 22x13" aluminum racing rad + FAL slim fans ($400 for all @ summit) *aem ems *i already have some gsxr1000 individual throttle bodies, i'll get a plenum made for it, and get those on the ka's intake runners *GT35R (i've decided to go with that *I already have a log manifold /w t3 flange and 38mm external wg flange in it *Tial 38mm i already have *i have 550cc injectors but i may go bigger *9:1 wiseco pistons *Eagle rods *Commetic HG *ARP head/main studs *Brian Crower stg 2 cams /w springs & retainers *Port the head *possibly a 50-125 shot of laughy gas *i can't afford another OS Geiken super single, so i'll probably go with a clutch master sprung 6 puck *3, maybe 3.5" exhaust *i'm indecisive about water-air or just all air fmic, i just don't have much room up in the front *Blitz Bov times 2 and that's my recipe for this Datsun go-kart, that thing's a blast to drive with ~110rwhp, i get beat by a 1-2 cars vs my friend's with stock sr'd 240's so with 500rwhp it's gonna be a blast. my goal is to have it all done and painted by the end of the year.... i'll keep you guy's posted....or just post some vids when my "talk" turns into a tangible street car thx manny =] any more ka-t guy's?

Administrators RTz Posted February 14, 2008 Administrators Share Posted February 14, 2008 I've often thought a KA-t would be just about the ideal powerplant for a 510. There's a local chap that's done just that... and then some. Its one of the most impressive 510's I've witnessed... . . . . 4-link rear suspension...

The rod snapped and blew a hole in the block after shattering the girdle,but it wasnt loud...impressive! Is the engine made of lead? Quote Link to comment Share on other sites More sharing options...
mannyvig Posted February 15, 2008 Share Posted February 15, 2008 I kid you not. The exhaust is extremely loud but it didn't sound too abnormal. Quote Link to comment Share on other sites More sharing options...
Z U L8R Posted February 15, 2008 Author Share Posted February 15, 2008 very sexy. i have to measure under the core support in front of the radiator and see how much room i have for a little front mount....if i don't have much room i may have to go water-air intercooler...

Skids260 Posted February 19, 2008 Share Posted February 19, 2008 Ka-t is the route i am heading in for my 510 as well. I would be extremely happy with 300 to the tires, espically since my l20b feels like it may be putting about 65 to the ground. Quote Link to comment Share on other sites More sharing options...
jerryb Posted February 19, 2008 Share Posted February 19, 2008 Im almost finished turbo charging an 89 3 valve engine in my 240SX track car. It has a log manifold, a Z31 turbo....no intercooler (for now) Stock head. The local NISSAN techs tell me it should be able to run 5 to 6 psi with no changes. (its a real BUDGET car!) It may end up with a hole in the block as well.... haha........... KA-t would be much better! Quote Link to comment Share on other sites More sharing options...
Skids260 Posted February 20, 2008 Share Posted February 20, 2008 Z U L8r there is plenty of room in front of the radiator for an intercooler www.mckinneymotorsports.com has them for 510s. Also this is the car that sorta spraked my interest in a KAT 510 http://www.turbophile.com/feature_cars/ron-ka24de-510.html this car also has a front mount.

Z U L8R Posted February 24, 2008 Author Share Posted February 24, 2008 that's a bad ass 510, i love the primer.....just something about it makes the car more intimidating. was good meeting u, i'll definately be in touch and thanks for the ideas/help finding parts. i'll keep my eyes out for a ka, in fact i think lethal's got one, i'll try and get him down on the price lol. take care, Dave =] Quote Link to comment Share on other sites More sharing options...

Was it moreso that you already had the motor for free or did you make the decision on other factors? I was honestly thinking of putting an SR in my dime just because that's what I've always wanted, but I was intending on keeping my motor relatively stock unlike you. I was just looking to daily my 510 and maybe slap on a GT28RS or GT30 (older style) and basic supporting mods for that and call it a day. Was just thinking I'd go with a factory turboed motor? what do you think Quote Link to comment Share on other sites More sharing options...
Z U L8R Posted February 28, 2008 Author Share Posted February 28, 2008 should be fine for what you wanna do with it. rocker arm stoppers are your friend. doesn't really matter what u put in a 510, they're so light anything'll make it fun as hell to drive. i could put a 28/71 on the ka now, run 7-10psi on stock internals and probably make somewhere in the high 2's - 300 range and scare the ♥♥♥♥ outta myself. but with me it's either stock or 2000hp so i'd rather just do it right once and pray i can get a year outta the motor, beating it's ass everyday. lol Dave =] Quote Link to comment Share on other sites More sharing options...
Nismo280zEd Posted May 1, 2008 Share Posted May 1, 2008 I may be a little late in responding but I would strongly advise you to reconsider the 20 over. The KA24de is already an over bored motor and if you plan on making 400-500 hp I would NOT bore it out any more than absolutely necessary. Also check out AMS for rods, cheap and rock solid.

I agree. unless you use shorter con rods to lower compression. Actually, lowering the compression on KAs is ideal on a turbo application. What fuel management is everybody running with the KA-T?
