I'm saving up to do my 240 project, and am in the midst of my research phase.

As such I thought I'd get some input from a more knowlegable base then... well me.

I'm looking to do an S14 prefer the 96-98 but if all I can find at the time is a 95 I'll live. I'm hoping to find one bone stock so I can develop a relationship with her :)

The goal here is to run from 200-300 rwhp with handling to match in an otherwise unmodded (read as sleeper) car. Also would like to keep the KA... in my area the torque is better for you, and honestly I am too damn cheap to have to worry about expensive SR replacement parts. Also hoping to not Turbo Charge. I live at around 7k feet so the benefits of a turbo slip a bit from the sea level folk!

So what engine/transmission/suspension mods would you do. Assume a 4000 budget (that's after procuring the car) and I'll be doing all the work myself. nothing is out of range, from complete rebuilds to simple bolt ons it can be done.

Be specific please as I'm trying to compile a price list and budget out the entire project through the winter!

Thanks!

whats wrong w/the 95's the only difrance is that they have OBDI instead of OBDII.

200-300 RWHP with no turbo? You'ld need forced induction or NOS to get there. Especially at higher altitudes. High altitudes affect NA cars as well. With a turbo you can turbo up to boost to achieve the same Mass rate of airflow and should make nearly as much power as it can at lower altitudes. The biggest limiting factor being the heat generated from the additional boost, especially if it starts to operate at a point where it is not as efficient. An NA motor will be limited to only what the weight of th atmosphere can push in. Which will be less than at sea level. To achieve the kind of HP you want without forced induction or NOS, you're gonna end up with a motor that you have to wind out, probably won't idle at less then 2-3000 RPM, will require race fuel, and probably wear out quickly.

:Werd

that kind of power is gonna be very diffiuclt to get w/o forced inductino of any kind.

95! I know everyone likes the mean look of the koukis (97-98) but the zenkis (95-96) grow on you and you can always do the conversion. OBDI > OBDII ;D 200-300 N/A HP is definately possible but on a 4000 budget it will be hard. A lot of shopping around and you'll have to DIY. If you want to keep the KA around just get the GReddy turbo kit IMO. I understand you're at a very high altitude, so the benefits of turbo aren't as great but the GReddy kit should get you to 200RWHP. My friend makes like 230ish RWHP with the GReddy turbo kit, intake, downpipe, testpipe and cat-back @ 6PSI at around sea level.

200-300 RWHP is definately possible on the KA. The GReddy turbo kit will get you over 200RWHP on the KA...

why would you say that?

it is posible, just goiing to be very hard on a $4000 budget

Trying to double the stock output of a KA without forced induction sounds difficult to say the least.Doing it on a $4K budget is even more challenging.And doing all this on a street driven car will be nearly impossible. From my understanding, 200whp from a NA KA24DE is near the practical limit.Airflow is a determining factor in making power. It will be very difficult to flow that much air thru a KA without compressing the air (or using a 100shot of nitrous).

First off...

Really have nothing against the 95... it's just that they seem to be, as a whole, in worse shape then the later years. I actually like the 95/96 front better then the Kouki. Also seeing as the hope is for a car with around or less then 90k miles if I can, the later the year the more likely the low miles!

Second off... I'm in the lovely foothills of Colorado

Third: 4000 is the stating budget. It can only grow from there as new parts are added!

So what I'm hearing thus far is that without Turbo charging I'm outa luck with my stated goal... fair enough that's why I asked :pface That's a-ok with me, just always had a hard time with tuning turbos, but a boys gotta learn sometime.

So again back to specifics, For a turbo setup running an expected 6-12 PSI what is the best Cam/Valves/Header and such. Also what CAI and Catback would you recomend.

And finally, what are the best Bang for buck Coil overs ATM. I want something Adjustable that will allow for better handling then stock, but not Outrageous in price.

Coilovers = Tein or JIC

CAI = dragon intakes/weapon-r

Cam = JWT

Header(or in the case of a turbo an exhasut manifold) = Greddy

Catback = Apex'i or Greddy (many people will probably say BRM

these are just my preferences

Greddy sells its manifold separately from the kit?And youve seen over 200whp from a KA without nitrous? I'm sure they had high comrpession pistons and some great standalone management. With those kinda prices, its cheaper per horsepower to go turbo. If youre a NA kinda guy, then more power to ya, but I dont think you can beat a turbo's bang for the buck.I dont know much about NA KA. The 200whp is a number if heard used a lot on this board.
