Need some tuning advice, what should I do next...

[Chaotic_Warlord]

Ok here's the story, I have a 95 S14 with a mostly stock KA w/ roughly 150K on it that I swapped in when I did the 5 speed swap. So far I have an MR Header, DP , and TP connected to a Buddy Club Pro-Spec 2 exhaust. The engine I pulled out has well over 250K on it so it will be my new rebuild project so keep in mind I am going for an all out KA-T setup, but am looking for some mild perfomance gains in the process.

Here is what I have planned which will then be carried over towards the built KAT. I have a very open breathing exhaust setup so I am looking to open up the breathing of the intake setup so I can level off the reduced backpressure fromt he exhaust. Since the exhaust is a 2.5 4 to 1 header setup that feeds into a 90MM to 115MM straight exhaust my backpressure is way less than stock but the Butt Dyno says I gained at least 5 - 10 HP on that alone.

Now I am looking at my intake and fuel options, since you shouldn't alter one without the other. My lineup for what I plan to get over the next couple of months are as follows

- 80mm Intake manifold for Excessive Motorsports- Short Ram Air Intake with the Apex'i or Blitz Filter- 370 cc Deatchswerks KA injectors - Walbro high flow fuel pump- Adjustable FPR- Steel braided fuel lines- Z32 MAF

Now with all of that I know that I am going to need to get an ECU tune but I haven't the slightest idea who is better Enthalpy or JWT or what I need if i do it myself, the whole ECU tuning is just confusing. I am half tempting to just fork out the money for the Greddy pggyback and the Apex'i SAFC (or could i just get the Apex'i NEO and swing it on that alone)

I am also looking to get a Wideband O2 setup and maybe a couple other goodies for the interior (looking into gauges right now)

Now for the flaming to commence, with this setup on a stock engine block realistically what kind of power gain could I look forward to. Once this is all done (hopefully by May) I may proceed with a small turbo install pushing a max of 8.5 - 9 psi., this way I'll have some experience with a turbo while I build up my other block.

Ok guys give it to me, does this sound like a sensible way to go or do I have things all skewed?

Nice to meet a fellow philadelphian for a while lol.

I would go into suspension first if you hadn't done it yet, maybe some coil overs,tires or lsd to help out the tractions of the power your getting.

- 80mm Intake manifold for Excessive Motorsports- Short Ram Air Intake with the Apex'i or Blitz Filter- 370 cc Deatchswerks KA injectors - Walbro high flow fuel pump- Adjustable FPR- Steel braided fuel lines- Z32 MAF

I wouldn't bother spending all your money on most of those stuff unless you find it for cheap but for a na ka no need to buy and install it. Just buy a good air cone filter no need for the piping (intake doesn't make much hp on a ka) Intake manifold you could just make one yourself (there's a thread somewhere on diy) Work on your suspesions first then save up your money for the turbo kit.

[Chaotic_Warlord]

I'm working on upgrading my suspension but want to get started on my fuel and air systems as well so that I can go turbo

[neverlift]

well if you plan to install all those fueling upgrades without control your not going to have much luck. 370's might not be enough fuel for too much more then 9 psi yeah you could push it but why try,when 550cc's are what 10 dollars more.... The walbro and afpr are good ideas but not needed till you boost....Excessive manifold IMHO is just that..... Cone filter always a good idea...Z32 maf again not needed till boost,but will give some throttle response.....

Ok just listen to this if you'd like to hear my input.. Spend the obscene amount for the manifold on a pulley,light weight flywheel,and 1 piece drive shaft(steel or aluminum) and free up what you have already... If you look hard enough you can snag all those up for less then the manifold,also a major point you should consider is the wideband GET IT FIRST!!! you will need to see your afr's once adding fuel,and with the injectors and new maf you will need to atleast get an afc to lighten up the fueling... Also some sort of timing control for the in boost areas

oh and what he said about suspension/tires....

[Chaotic_Warlord]

I already have a steel 1 piece driveshaft and I read somewhere that the lightweight pulley is just a waste of money and puts unneeded stress on your belted components. As far as the lightweight flywheel goes, I'll get that when it comes time to replace my clutch which hopefully won't be to soon. Again the suspension setup is in the works, I plan to go with the Tokico D-Spec and a set of performance springs (going to look into either the RSR ones or Espellir since they seem to be the best for the money.) I am not going coilovers just yet due to my money being tight and I'd rather have a nice spring/shock setup first and put that extra money towards my KA rebuild and boost.

Since the manifold seems to be overkill on an NA application I will take that extra money saved and put it towards a turbo setup. I don't want to go 550's just yet, I'd much rather start out with the 370's and upgrade as I make more power.

"2.5 inch exhaust"90mm = 3.5inches115mm = 4.5inchesWTF?

Dont let the ear dyno confuse the butt dyno!

Just get the Greddy E-manage Ultimate. The best thing would be to get an ECU flash and have the emissions stuff removed then use the Greddy to fine tune. The E-manage Ultimate is great because of its aux ports that will allow you to run a wide band O2 sensor, MAP sensor, and MAF all together.

[Suicide.Veteran]

^^^yeah if you can figure e-manage out.

wideband first. Innovative lc-1 data logging so you can watch the road while tuning, and its less than $200.

then SAFC. Yes neo is pretty and colorful, and I want one, but a used safc 2 will work.

then 370cc injectors, but why not get essarrrrgh 370s and save money for 460s or something later, cuz when you boost, you start to crave more.

then z32 maf.

walbro pump and fpr are best bought together imo

if your gonna boost, why get an expensive shortram? ebay 3 inch mandrel bent.

maybe 20hp max, but it's a good prep for a turbo.

I have a whole emanage setup I am selling, email me.
