Future KA-T build,Opinions?

[8Nismo9]

I decided to turbo my KA,i am going to do a mild build.Nothing crazy just to get me boosting.Im looking for 280hp reliable.As of now this is what i have.Any Help would be great and things im missing from my list.Also thinking of throwing some cams in.Now what spark plugs to use and gap.i know 1-2 heat ranges colder and i heard gaping at .35 for starters.i know its different for everyone since it depends on their build,so what would be suitable for mine?

S15 Spec R T28
Nismo 550cc Injectors
Megan racing Test Pipe
JGS t25/28 line kit
Blitz Blow Off Valve VD
255 walbaro
N60 Maf
Powered By Max Flex Cobra DP
Powered By Max High mount intercooler
Powered By Max T28 Turbo Inlet
boost,oil pressure,wideband gauge
z32 fuel filter
ISIS V2 Turbo manifold(bottom mount)
3in cat-back blitz nur spec exhaust(since i already have it)
Enthalpy Tune

dont worry about cams, the stock KAs arent to shabby, your list looks like youre ready to go, might wanna get at least a wideband and a boost gauge though.

[punxva]

as stated above you really don't need cams at this point. Don't forget an intercooler good luck on the ka-t.

Im looking for 280hp reliable.

Are there any reliable KA-Ts?

[sirfallsalot243]

That turbo wont get you 280whp. But itll be in the ballpark. I'd also add a z32 fuel filter, and youll probably want a turbo manifold of some sort id assume. lol.

[redpotatoes]

Go with a little bigger injectors, 550cc if possible.
You can get N60 instead of N62 if you want.
No need for a Z32 filter.
Koyo rad isn't necessary.

Yes there is a lot, my setup is very reliable. Tuning is the key

agreed the only reason i blew mine was i dented the oil pan and starved the motor of oil. It's all in the condition your motor is in or how it was built and how good your tune is

pros/cons between them?I know some of you said don't need cams but i hear some people use the s13 cams,guess its all preference for what I'm going for.

also updated my list a little bit

[redpotatoes]

N60 is usually cheaper than N62 and can be found on maxima 89-94. Either one is fine.

S13 cams is a upgrade but need to be degreed properly, the 4ccw method will work but it won't be optimal.

Ah OK.did a little readying,seems n60 would better suit me since im not going for big numbers.And with the cams ill just leave the s14 cams in

[ATLspeed]

Don't bother with the 248/248 cam (s13s cam mod) unless you adjustable cam gears...but either way its not needed. If you don't plan on shooting for more than 280hp then the 550cc's will be fine...but if you can snag a bigger flowing set of injectors do it as you WILL want more after the bug hits you

Yea I'm not gonna bother with the cams.I'm going to try my hardest to not get bit by the bug but it seems that everyone gives in.

What other opinions do you need? On what topic/parts ?

anything really,just trying to make a soid build here.Actually i was gonna see if i should use a JWT ECU since im not going for big numbers.

Last time I turboed my KA it had 270whp @ 9 psi with the A/F ratio @ 10.8 (rich). My set up was:
Garret T3/T4
Z32 maf
SR 370cc injectors
255lph walbro fuel pump
malpassi [email protected] fuel pressure regulator
Ebay FMIC Kit
Ebay TM manifold
Ebay 38mm wastegate
SAFC II


New set up coming soon :), GL with your project!

pretty much right around what I'm shooting for.ill see what numbers i can push around the same PSI.thanks

Your welcome, if you need help on anything, feel free to ask bro.

Your welcome, if you need help on anything, feel free to ask bro.

someone said a wide band O2?still geting trying to understand everything.Kinda new to turbocharging but iv been doing my homework.

[GroundPerformance]

You're list pretty much covered the turbo,exhaust,fuel systemand etc but missing the critical of all which is Tuning. While at the power goal your aiming Rom Tuned ECU will be just fine with an SAFC for fine tuning. I would still recommend Nistune for future expansion. As for the turbo manifold the best one out there is the ISIS V2 KA24DE. I can prove since I actually had the P2M,SSA,ISIS and by far ISIS stands out bar none. GL with the project.

No isis, no ssac, no none of that noise. Just find one of these. And pay the quality price for just that. And prob the best made ever for the KA. www.ka-t.org :: View topic - AMS turbo manifold group buy (http://www.ka-t.org/forums/viewtopic.php?t=31087&postdays=0&postorder=asc&start=0)

Perhaps you didn't read the OP specs list. While AMS is the best quality turbo manifold they don't make one for a T2 Based turbos. Now let's say for some reason they make just for you for all that noise you're making as well. Now we are talking 1000+ just on the manifold. The way you're going at it might as well throw in a AEM EMS for tuning. These are nice cool parts no doubt but now we're more $$$ for a 250whp+ car.

Ditto. That's just rediculous to spend that amount of money on a manidold unless your going for baller points. Just get the ISIS V2 bottom mount (better then the thin walled ssac manidolds) and heat wrap that bad boy to keep temps down in the bay and near your BMC.

If i had the money and my build was different i would be all over that but thats not my direction nor in my price range.im trying to build a kit around the same price for the greddy kit but with more gain in power for the price

go big or go home. There are others out there that are somewhat similar for a couple hundred less. But good luck to you.

How about build something and stop day dreaming.

baby steps my friend baby steps.thanks for you input

thats what im doing,done day dreaming about motor swaps and big numbers.i just need somthing to have fun with and reliable

[sliptones629]

Did I miss the part about why bottom mount and not a log?

[8Nismo9]

Did I miss the part about why bottom mount and not a log?

never talked about it.i chose bottom mount for heat reasons and easier down pipe fitment

[sliptones629]

so go to jgs or the fs section and get a log or make one for the best clearance. moves more away from sensitive areas. if you buy flanges, its easy to have someone fab you a d/p to fit your setup. maybe you can get a deal and they can do your i/c piping too.

[keistyle]

Are you going to rebuild first?

yea i could do that.i got a buddy who could weld it for me

Are you going to rebuild first?

im not sure my motor is at 128,xxx as of right now.I think with my set-up and a good tune,my motor should hold up just fine.I did some research and enthalpy seems to be a good candidate with a SAFC

[keistyle]

Gotcha.

I want to do ka-t too. .

I am for sure going to replace piston rings and all the bearings.

might as well do a head gasket too

[Turbo Nismo]

And don't forget to put some ARP Head Studs.

[GroundPerformance]

If you have a good running KA I would just rock it as is and not touch it other than prepping the motor for boost by removing emission crap and replace intake/exhuast manifold gaskets. With a good setup and tune you will be fine. If you're experienced with rebuilding and know howto check for proper clearances,bearing grades and torque specs/sequences go ahead they are on the FSM anyways. I just don't want you to waste a perfectly running KA. If you still insist go picked up a KA with a bad HG and mess with that.
