248rwtq

At 10 psi on the stock MAFS. I will post copies of my dyno sheet soon

setup:
SR T25
SR side mount
SR 370cc injectors
SS equal length botttom mount manifold
2.75" full turbo back custom exhaust
300zx TT fuel pump/ filter
SAFC I
ACT stage 2 clutch
Injen filter and intake

[SR20d2fourT]

Damn thats some good torque!!!!! Good job man, cant wait to see what you do w/ it :D

[go240]

nice numbers. kinda like mine - made a lot more tq than hp

[ass15]

about yr ago, on fmu 8:1 did 201whp and 237trq. started to lean so stopped before 5 rpm...

now putting together a t3/t04e setup w/ jwt ecu, sr 370cc

[SpeedMonkeyInc]

That must be fun to drive. Seems like that tiny turbo would really choke flow. How does the motor feel over 4500rpm or so?

[mistaanime]

nicceee....same setup i will be doing..juss missing the injectors, fuel pump and oil lines..where did you get your lines from?

[s14unimog]

jgc percision parts from KA-t.org HIGHLY RECOMMEND!

[BigVinnie]

I'm assuming the ecu is still stock. That is why the torque numbers are probably high.
Those are some pretty positive results, with an ecu tune you should kick some serious ASS..

[s14unimog]

yeah stock ECU with the SAFC I

A tuned ECU will help but with 370cc injectors and a T25 there is not too much more power to be had.

[AutoRnD]

whoa buddy
you need tuning badd...
that is pretty low hp...
no offense.
i got ka-t as well
not running yet
just get tuning.. and you should be good...

[SpeedMonkeyInc]

It is low HP but its typical of T25 KA-Ts.

[s14unimog]

that is straight off the dyno my friend... it maxed out my stock s14 MAFS so I need a Z32 before I go back.

[mistaanime]

yea..with a t25..thats pretty good horse power...i believe if you wanted lots more then you'd be runnin a t3 or t4 with stronger cams, pistons and crank shafts...i've been told ka stock internals can handle just about 240 horse power..before things start breakin hehe..

[2iv0 sx]

Nice for a Ka-T! how are the internals are they stock?

[golfer17]

pretty good #'s. you should be able to get a lot more out of that t25 though with some supporting mods.

btw, if its not your daily driver, you can try putting 400whp through a ka, its a strong little motor. it will eventually break at these levels, of course, but there are two guys around here who are making around those power levels and running high 11's. they are both street cars also, and even daily driven somewhat. and oh yeah, both of them have excellent tuning also with dsm ecu's (much better ecu's), so maybe that is why they havent broken yet.

[s14unimog]

yeah I really didn't want big numbers. The 248 really surprised me. The internals are stock and hopefully she will stay together for daily driving. I'll let you know if she goes out on me

[DeSantes]

Any pics of your setup?

[s14unimog]

this is a progress shot, I havn't taken any final pictures

[ranisron]

dang the BMC is sitting pretty close to the turbo manifold.... heat wrapping??

Same with the Powersteering reservor. I think the BMC is more important to be protected though. Raditor cap looks like stock 0.9 Bar one. Get some 1.2 Bar at the stealership.

nice looking :)

You where told wrong. Completly stock KAs have been known to make 350 plus for a while before the ring lands give up. Stock rods are not an issue to 400 plus. The crank is just fine the way it is.

[NemeGuero]

+1 for speedmonkeyinc with the good info.
Yes his power numbers are low, but he is using a small turbo and doesn't have any tuning.
Good job. Keep it up.

Actually this is false....
ABEL racing is running 2 KA's on stock internals, using the DSM ecu swap and 1 G sensor, CAS, and wideband o2. Max HP at the wheels is 386RWHP.

Those numbers arent that bad if you consider the 15% degredated loss from the drive train.

It is low HP but its typical of T25 KA-Ts.
This is correct alot of guy's that do the KA-T platform would usually go with a T28 over the T25 for the larger displacement of the KA (T28 is found on the RB20).
As far as the HP being low that can be corrected with shifting the power band via distributor, and advancing the cams.
I added earlier to retune the ECU which would significantly shift around some of those torquier numbers for better high end HP numbers

Agreed

[NemeGuero]

Whats this about the DSM ECU swap? Can you point me to some information about it?

Yeah elks240 is running the dsm set up and is a member of Abel Racing, he could explain it to you a little bit better.
You can find him in the KA-t forums. His car is running 12seconds at 18PSI.

You could do all that and gain some top end, or you could swap out for a turbo properly sized for the KA and get a lot of top end.

Shifting the power band via the distributer? How does that work?

[NemeGuero]

retard or advance timing. (depending on application) that's how.

[SpeedMonkeyInc]

So you advance/retard the timing and change the power output, but does it really change the shape of the power curve?

john (elks240) actually dynoed over 400whp recently and broke into the 11's. him and and efeezi are the two guys i mentioned earlier, and i hear abel is starting to build a drag ka-t with 10's in mind (might be just hearsay, but they have some really fast dsm's that are built extremely cheap). the ka is one hell of a motor, i probably should have built mine instead of selling it to john, but overall i still like the sr better.

[BigVinnie]

I mean if you think about it, changing the time in which the chamber will make ignition your changing the scope in which power is made. So if the piston ignition is sooner you would be making high end numbers, that would make HP. Think of HP as High End, and Torque as your low end. Advancing the timing through the distributor is just shifting around torque to HP. But it wouldn't properlly be done unless the cam was timed to the distributor. It is the only correct way to shift and move around numbers.
So yeah if you think about it the curve does change.

[s14unimog]

mines retarded to 13 stock is 20... safety over power

[BigVinnie]

mines retarded to 13 stock is 20... safety over power

That also explains the loads of torque your engine is producing...
You could just run a higher octane possibly, and use some iridium plugs, probably leave it retarded at about 17~18............

Changing the timing mapps to the ecu can easily put you back at 20 possibly up to 22BTDC, and with the right octane, with less use and tuning of the SAFC.

[projectRDM]

True, bringing the timing back but using an adjustment (EManage does it, but a simple MSD controller would work too) would give you full range of ignition through the powerband.
