I had a new turbo built for the PhatKA-T.com project car and slapped it on today and made some passes on the dyno.

404 RWHP @ 5500 and 409 TQ @ 4100 16 psi boost

Power band is HUGE with 300+ TQ from 3200 rpms to redline!!

I cant believe how much power this motor is making in stock form. Something has to give... right?? The car makes clean pulls without any hint of ignition issues or missing a beat. Not a peep out of the knock sensor (I hope its still working).

What is the record for stock long block KA power anyway?

On a side note, while adjusting the boost controller, we accidently made 18 psi for about second before we let out of the throttle and made 431 TQ.

What all is done to the engine? And what are some specs on other stuff? Does this car see actual street/strip time boosting that amount? If you don't mind.

Hmm the difference here is you dont have to buy and SR when you already have the KA? SR what indeed. for a diff of 140 hp I would rather turbo the KA haha save yourself 2500 plus shipping and other miscellanous stuff to make the engine work.

Yes this motor is bone stock. Never been opened up. The same pistons, rods, cams, head gasket, etc that was on the car 13 years and 114,000 miles ago when Nissan built it are still living under this torture.

I hope that the Enjuku race car isnt the car that everyone keeps bringing up as the "stock" SR that made so much HP. Here is a list of some of the mods that their web site has listed for that car:

Engine:S13 Red Top SR20DETGReddy Intake ManifoldGReddy Aluminum Pulley KitHKS 272 Step 2 CamsHKS Rocker Arm StoppersFerrea Valve Spring KitER Custom 1.1mm Metal Head GasketMSD DIS 4Fidanza Lightened FlywheelEnjuku One Piece Aluminum DriveshaftBogart Flystar 15x9" Drag WheelsBogart Flystar 15x3.5" Skinnies

This doesnt exactly sound "stock" to me. Stock short block maybe, but not a stock long block for sure.

Another thing to note is that it may have made 544 WHP but ONLY MADE 412 TORQUE. The dyno run I posted shows 409 TQ and the run before that while adjusting the MBC we accidently got boost to 18 psi and made 431 TQ before letting off. I guess I didnt just shatter the KA-T record, but I KILLED the SR TQ record at the same time (for a "stock" bottom end).

Just so everybody understands, this KA has a STOCK intake manifold, TB, Cams, Valves, Valve springs, pistons, rods, crank, block, head gasket, head bolts, coil, etc, etc, etc.... All I did was put a turbo on a STOCK car, an intercooler, fuel system, and engine management. Nothing more.... OK.... It has an Apexi exhaust too... Sorry... No lightweight flywheel, underdrive pullies, lightweight wheels, etc... Just a bone stock KA with a turbo on it..

Impressive. I knew there was more power to be found in the stock KA.

Ivan, care to share what turbo you are running? If you have some proprietary specs that you don't want to share, that's fine, but as much detail as you can would be nice.

The first turbo was an SC50 which is a GREAT turbo. This turbo spooled quickly and produced the power we wanted and then some. Although it was no where near tapped out, I wanted to test out some of the new Garrett GT technology. The new turbo is a GT32 with some special twists and tweaks that allow it to spool quicker but limit the power by about 50 hp over the standard GT32.

When I got the turbo in on Tuesday, I was really supprised at how small it was. Both the compressor and turbine wheels are quite smaller then the SC50. Several of us at the shop thought that it wouldnt make as much power as the SC50. The first pull proved us wrong. The AF ratio went from 11.25 with the old turbo to 11.75 with the new turbo at the same boost pressure. This new turbo was obviously much more efficient and moving a lot more air. Spool up was a bit quicker reaching 14 psi @ 3200 in fourth gear. Over all, the turbo made more power at EVERY RPM.

definitely credit is due to ur tuning crew and aem ems. i think the hardware speaks for itself, but the magic has to be in the tuning.

No this dyno sheet isnt photoshopped. This is the way that the software prints it off. I dont blame you for doubting. These numbers are HUGE. I am still shocked with the HP numbers myself and I was there :)

Its wise to question what you see and read on the internet.

Being an established shop for the past 15 years and having the reputation we do, there is no need for us to lie about numbers. Anybody is free to stop by and see the charts on the dyno for themselves. Ask Matt, Phil, Norbert, Keith, Heath or anybody else in the area to stop by and ask to see the charts. The car is still there and will be making more runs on the dyno before it goes home. Your welcome to come watch.

The curves are jagged because this was printed without using smoothing. Just like the Dynojet, with the MD software I can click on smoothing and take the peaks and valleys out and smooth the curve.

Ah. Regardless those are amazing numbers for a stock KA. But the question now is, how long can the engine sustain those power levels?

I think most of the credit to this power and stability goes to the AEM management system, in turn, to Ivan and his crew for getting it to work and tuning it.

BTW- what kinda fuel you using for the 16psi run?

Congrats man thats insane. Will the owner be throwing in pistons, connecting rods, ect in the future? If so then it'll really be a monster.
