All motor 240 ideas.

[YaItsGotAHemi]

I am thinking about keeping the ka24e and going the all motor route...
I figure the obvious place to start is the 5 speed swap. But I want to get a higher geared rear end. The car will not be a daily driver so just about anything goes for the build.

Questions:
What is the highest geared setup I can use? And can you point me into a direction to find some info on it?

Do the KA24E and KA24DE use the same exhaust manifold flanges?

[stupid nissan]

how much power are you trying to make because an all motor build on a ka24e could get quite expensive

[trsilvias13]

ka24e and ka24de uses different exhaust manifold flanges.

If you want high output off the ka24e - contact robello racing in nor cal.

If you want high output off the ka24de - look up greaser (freshalloy member)

[The ROMAN]

The highest all motor KA I've heard of are the ITA engines that make 200hp. There is one guy on here who built a KA like that too, it shoots massive flames and runs on race gas I think? They are expensive and you need to really need to know how to tune them.

If you really want "all motor" best bet is to just make it easy and get an LT/LS series V8...or just limit your goals to 140hp and keep the KA.

Here's the 200 whp ka24de that is shooting flames

I think he was not quite at 200 on that vid though, but he is now.

His nick is Greaser_, he is on some other nissan forums

[racepar1]

If all he could get is 200hp on race gas the he wasn't doing it right! The SCCA GT2 and 3 cars use KA's and the single cam's make over 250hp! Besides if you wanna go monster you can make more than that because you are not limited by any rulebook. Brian Crower has a 2.65 litre stroker kit for the KADE's. That combined with a great head (porting, BIG valves, etc...), ITB's, high compression (like 12 to 14 to 1 high), race gas, cams, and a great ECU should be able to put more than 300hp and torque to the pavement.

[EJ253]

i think its pretty easy to shoot flames when your exhaust is only 2 and a half feet long

[supergoob]

how many miles is on your engine?

[YaItsGotAHemi]

2xx,xxx don't know specific mileage but i know it has to be tired and ready for a build. I have a Neon that is going to be the turbo project so i want an all motor build with a 240 and would be happy with a mid 13 second time. don't care about power levels. just want a nice powered nice looking 240. because a neon will never look nice.

interesting. i wounder if you could do all that and just not have to use the race gas and take the hit on power.... hmmmm good post.

[racepar1]

The KA's are MUCH more potent than mose people realize. You can get 200hp out of a budget build if you do it right.

[haz-e]

I never dynod my NA KAE motor, but it was much faster than my 180whp/ftlb KAET. Had 12.7:1 CR, custom cam grind care of PDM on Nismo Blank, P&P head, Port matched, balanced, straight exhaust, and ECU work, reworked intake.

As has been said its not cheap but its worth it. Its even better becuase most people thow out great motors when they swap to the faactory turbo'd ones.

Buy an FSM and become friends with a machinist.

[johngriff]

I would swap an S2000 Engine in before building a KA.

[KA240SX808]

Cervasa on 240SXF made 187 with:
Exedy Stage 2 Clutch
Fidanza 11lbs FW
P & P w/ 5 Angle Valve Job by Cosworth
Ferrera 1mm OS Int/Exh Valves
Ferrera Dual Springs and Retainers
Bc 272 Cams
Xcessive Intake Mani
Hotshot Intake
Dc Header
Catco 3"
RS*R Ex MAg
Cometic 91mm HG
ARP Main and Rod Bolts
Wiseco 90.5mm 10.5:1 C/R Pistons
Eagle Rods
UR Crank Pulley
Sard FPR
Walboro 255lph Pump
JWT Cam Gears
Thermal Intake Gasket
DeatschWerks 450cc injectors
Deso Iridum Plugs
Magnacor Wires
Crank Scrapper

[haz-e]

Just get a decent cam, exhaust, and shave your head before you invest in a NA KA. It'll give you a little taste Contact E1 Egriego (SP?) on here for a bitchin ECU tune.

I guess you hate torque or something then! There is absolutely NOTHING at all wrong with a N/A KA build. For the cost of swapping a stock s2k motor I could build a KA that would spank the hell out of an s2k motor! Shit s2k's barely pull on me on the straights with my stock KADE.

[johngriff]

Gotta dyno for your KADE?

[racepar1]

I dynoed it a few years ago when it was absolutely bone stock and it had about 140whp and 135 tq. It should have somewhere around 150-160whp and 135-145 tq, but the compression is a bit low and it seems to have lost it's oompth, if you know what I mean. I don't really understand why this is significant to this thread though.

[johngriff]

Because I would swap an S2000 Engine into a S13 before building a KA.

Thats why.

Greasers car is Totally radical. But, he spent money on his KA build. It wasn't cheap. ITB's and a standalone? No, not cheapening out at all.

Its just after that much money, I would rather just put an S2000 engine in.

[racepar1]

But the built KA would cost around the same amount of money as swapping in the stock s2k motor and the KA would have way more torque and most likely more horsepower too. I think Carrol Shelby said it best "horsepower sells cars, torque wins races". That is the 100% TRUTH right there. The s2k motor would rev better and have a better top end, but the brute force torque of the KA would rocket the car off the corners.

[KA240SX808]

And he's running 89.5mm Bore, my bad

[johngriff]

How much torque does a built ka make?

Well it looks like that one makes about 170lb/ft and it's only making 183hp according to the dyno sheet so it's not ridiculously built.

[KA240SX808]

Well he's got a good amount done but he still has some stuff he can do to push him past the 200 mark. He hasn't messed with the Cam timing yet, he still hasn't underdriven the whole system yet. an Z32 MAF would probably aid him with his tuning because the stock S13 MAF is an G60 60mm so, I'm pretty sure upgrading to the Z32 MAF w/ a custom 3" intake pipe could yeild a few more ponies.

[racepar1]

Things he can almost certainly do to make more power:
BIG valves
Race head porting and de-shroud the valves
HUGE bore
stroker kit
badass standalone EMS with a great tune

I'm willing to bet he hasn't done a ton of porting work on the head and manifold. He probably has the janky ass clamped on motorcycle throttlebodies rather than a REAL intake mani with throttlebodies that have the correct bore size. The intake manifold and head is where the vast majority of the power is on an N/A motor and most people don't want to break the bank there. But if there is one place that you wanna break the bank on an N/A build it is the head/mani!

[KA240SX808]

Yeah he Can still go w/ the 90.5mm Bore 10.5:1

These are his head flow numbers:

.500" = 379
Exhaust:
.100" = 106
.200" = 193
.300" = 253
.400" = 278
.500" = 281

and hes has 1mm OS Valves which IIRC are the biggest I've seen so far, head flows pretty damn well. and I'm sure and AEM EMS or Haltech could tune it better then that eMAnage Ultimate

[jspecusa]

jason's old setup:
stock KA24DE with injen cold air intake, 60mm pipping exhaust, and aem ems.
dyno'd 165 at the rear wheel.
that's without more work like bigger throttle body, ITBs, cams, ported head, header,more spark, and injector upgrade.
like everyone said NA route is fun, but not fast compare to the dollar per hp gain going turbo route.
240 are heavy cars, most NA setup are for light weight cars like honda, miata, or ser.
4.6 is the highest you can get, order it from nissan motor sport/westco justin.
I had the 4.6 on a s13 with sr20de, it was fun shifting but gets tiring after awhile.
good luck,

sam

But how does the manifold flow? The stock s-13 KA MAF is holding him back A LOT as well. Seing as 10.5 to 1 is higher compression than what he's got I'm assuming he's running pump gas, which is also holding him back. Not that I would want to run race gas all the time either. But there are a million ways to get more power, and after you think you've got all you can there are a million little tricks to get just a bit more.
