That's it...

155.0 WHP
155.9 WTQ

wow, thats almost as much as a stock SR20DET!!!
Awesome. That thing must be hella loud.

*s13 drifta* · 02-15-2008, 02:45 PM

Yeah I would have to say the buddy club spec 2 exhaust is the best performing exhaust I have ever tried, but its louder than shit without a silencer.

It would be nice to know what those numbers are. Also are those 232/232 or 240/248 cams?

Also the over bore decreases valve shrouding so the mushroom effect in your cylinder is more efficient.

Stock bore
Stock S14 cams... 232/232

All I did was:
Hone cylinder walls...
Had machine shop measure bore and check for roundness...
New main and rod bearings... Plastigauge to check clearances...
New OEM Nissan piston ring set...
Clean everything ofcourse... Chemical clean by machine shop...
New gasket set ofcourse...
Torque everything down to Nissan FSM specs...

Here are some of the pics of the rebuild...

Oil was dropped after every event... Filter changed after every other event...
6 oil changes in the last year... Haha!...

I believe in changing the oil more frequently than using over priced oil...

Here is a video of the car starting for the first time...

I just wanted someone to prove that different oils make different power numbers. No one believes me.

You should try Eneos 0w-50. Just once on the dyno.

But I don't want to turn this into another oil thread. Nice results, makes me want to rebuild my KA!

Z U L8R · 02-15-2008, 07:54 PM

i don't trust thin oils, i use castrol gtx 10w-30 or 10w-40 myself.

on first start up i use non-detergent 30w, let it idle for a second, then hold it at 1800rpm till it warms up, burp the coolant, top it off, drain the oil. then fill'er up with Rotella T. work my way from low throttle low rpm to mid throttle mid rpm, then to just a little before redline and wot within the first 60 miles so the rings etch in while there's still a fresh hone filing them down. and basically beat the motor's ass on the lowest boost possible using Rotella T deisal oil for the first 1500miles. changing the oil every 250 miles. then after 1500 miles, i'll retorque the arp head studs, and go with the castrol... but don't ever use synthetic on a fresh motor.

comp cams swears by rotella T for break in period. it's got ZDDP in it. zinc diaphosphate blah bla bla but the zddp in it may lead to premature catalytic converter failure so don't tell the dealer that's the oil u use if your cat goes bad before 8yrs/80k miles lol .....i love old cars...cats ftl...emmissions exempt FTW!

everyone has their own system/superstition i guess. personally i think synthetic sux. just my .02

ryan hagen · 02-16-2008, 11:22 AM

this is the nissan motorsports piston for ka-e, instead of a little dish, it has a little dome. i put it next to a aftermarket 9.5:1 dohc piston.

TheJerk · 02-16-2008, 04:08 PM

Awesome numbers.

Niice job keeping up with those Porsches

DarkPhoenix · 02-17-2008, 03:23 AM

Wow!! The KA always seems to impress me. My car has 115k on it (KA24E) and the car feels faster than my Galant. (2000 Galant ES 4g64 SOHC 16V, w/ Outlander intake mani, Megan Racing cat-back, ebay short ram intake, adjusted timing and a tune. It put down close to 165HP at the wheels before the tune and timing advance. My Galant weighs 3250 lbs with me in it and full interior)

I plan on getting it dynoed as a baseline for whatever work I do. For now the car is completely bone stock. Not even a drop in filter yet.

Great job on the NA/KA build.

From what I understand the castrol GTX oil has some of the best polymers for a conventional blended motor oil. I use the 10w-40 castrol gtx and I changed to fresh oil the same day as my dyno, I actually believe it helped gain a 1 to 2 HP on the dyno, then using any other conventional oil. Most people that I know that work on Nissans often recommend castrol GTX, it's good stuff and cheaper than mobil 1, I wouldn't even mind using the synthetic if my engine was newer.

TravisSW · 02-17-2008, 09:18 AM

Correct me if i'm wrong, but isn't the stock factory HP for a DOHC 150hp?
Info:

/hides

Either way, I'm waiting to find another KA dohc to build up.

I have ITBs waiting inside my garage.

Big difference there buddy.
Degradation loss to the wheels is estimated between 12~25% depending on the vehicle.
To the wheels a stock KA DOHC will make about 132 HP on the dyno.

ryan hagen · 02-17-2008, 09:33 AM

the head bolts need to be replaced during the rebuild. how about the mainbolts? im using arp headstuds, but i did that just cause of the compression i was going to run. how about main bolts? i used arp main studs on my ka-t but didnt want to put that much $ into my n/a build, i built it mostly out of spare parts.

i could put my short block together today if i re-used my main bolts, otherwise i m waiting till i call in or go to a dealer, i priced them out a couple weeks ago, mainbolts were about $4 for several and the others $3 something.

Nikeboy355 · 02-18-2008, 12:11 PM

Shameless plug... I'm selling majority of the parts off this car to rebuild the chassis... And to build a monster NA KA motor for it...

#/f/showthread.p...95#post1827495

I want to send the chassis to get caged while I prepare another motor... Help me spread the word...
