KA-T Declaration of Specs THREAD

[byhi]

Hey guys, I just wanted to see who else in the world is KA-T. I'd love to know specs, Dyno results, thresholds, experiences, as well as see some pictures! This isnt meant to be a FAQ thread, but more of a "heres what im doing" thread

For instance.

1. posts specs/mods
2. post how long it has lasted
3. numbers you've made on the dyno
4. what and why it blew up (if applicable)
5. experiences, thoughts (pros, cons)
6. pics are always welcome


i will start, because it would be lame if i didn't

new setup for 2007

1. KA24DE block bored 0.040 thousandths over (just shy of 2.5 liters)
- Wiseco 10.5:1 pistons
- Cometic .060 (thicker than stock) Headgasket
- Head QZ removed = lower displacement + quicker late combustion sweep
- Effective compression = 10.1:1
- ARP head studs Studs
- Micropolished crankshaft
- complete head and valve overhaul (love starting fresh)

- Custom MurphyBHP tubular Manifold
- Cheapturbo.com garrett 50 trim turbo
- JGS precision wastegate

- JGS precision Motor mounts
- Siemens 560 cc injectors
- greddy fuel rail

- greddy emanage

- Fidanza Flywheel
- Spec stage 3 clutch

- V mount intercooler setup with blowthrough Z32 MAFS





2. This one is almost fully together, im super excited to tune it and get it out there. But ,my last setup was without an aftermarket headgasket, and blew the stock one at 12lbs.... .after 8 miles of driving,.... ouch, but i expected it. So i wasnt too mad. But this one should be good for 12 lbs (and thats beign careful since its a high compression boost motor.

3. No numbers yet, but with a full blown turbo power calculator and being very pecimistic about intercooler efficiency and a low duty cycly it said i should make 340 whp at around 5500 rpm, and 370 TQ at ...... 3500 rpm... wow

4. easy, it blew up because i got power hungry and i knew we were doing a full build for the 2007 season, so i had fun with it, no biggie

5. With my experiences are the common experiences with what everyone says.
- the KA makes awesome torque but has some reliability issues whereas the Sr is a good motor too, and it is reliable, jsut not as powerful without a boost-hike or a turbo upgrade.
- Also, the KA (for me) seemed liek the right choice as i have the minset that you should never give away displacement... sure we could argue about circuit cars etc etc, and im NOT a muscle car guy, i just saw the 2.4 as an advantage especially since the guy that im co-building with (learning new stuff everyday too, this kid can literally reassembly any nissan motor with not one ounce of help, its insane) has built several 500+ whp KA-T's (including his wifes) that have all been high compression turbo motors, and all have been blasts to see in action!!

6. look for a pics update in the next week, right now all i have are pics of the block and head, and other random finished parts, so i would love to wait until the motor is fully together to put up a pic or two for the fans, lol. also i will take a pic or two of the V-mount upon completion and maybe give them a post-up.





anyhow, what else are others doing out there, share your experiences, im deffinately interested to know who else is doing what. thanks
