ka24de all motor questions......

[98frontier_islander]

time and time again youve heard it and before you say search i have.

before i dish out the cash maybe someone whos actually done this can give me some help.

200hp at the wheels is my goal.

money is tight but willing to experiment.

and no i dont want to turbo so please if you dont mind dont mention for this kind of cash you can swap in this or that motor.

now i was wondering if i can use the stock ecu reprogrammed of course without a standalone or any other sort of engine management.ill get it retuned/chipped after all mods are done. lets say though would it work with upgraded injectors.

would itbs with a plenum and maf sensor cause a problem.

revving high isnt an option due to its HCW crank so im staying realistic.

HC pistons while using 93 octane pump gas.lighter rodsstronger rings.020 overbore since the engine is quite old.mildly ported head not to drastically affect air flowoversized valvesangle job,not quite sure yet.aggresive camsvalve springs to match camsstock manifold port matched and polished, andunsure of what tb to use if the itbs dont work out.headers,no cat 2.5-3 inch exahustair intake,maybe a custom ram.(once again if itbs dont work out)nos isnt ade but after its all done maybe try it out.and every well worth bolt on, no snake oilmajor engine tune up as well.

im looking overall at a 2800 budget for a measly 50 hp upgrade but one tank armored engine.i plan on keeping this vehicle and not selling.so before i buy i would like to know if its all good.thanks guys.

well..where to start...

#1.)one of the weekness in the ka24de is the intake..itb's would be a way to bypass the week anemic intake many.#2.) the exahust ports as tiny!..having the ports widend out would shurly help that issue..#3.) the stroke!..its a long @ss stroke man..so upper rpm power is not to be had..

the real benifit of the power plant is its torque to horspower ratio..its baddass..with the rite set up you could unleash tire shredding, noise making,lung choking smoking bliss!..

there are a few ways of awaking the monster but it will be an investment.

A.) high CR pistons...10.5:1's or better!B.) Cams..this is a must! your head porting will benifit more with a good cam.C.) intake..you have to decide this bro..itb's or fuel injected....itb's are friggin leet ..but injection can be tuned to deliver fuel where your fuel map shows holes..D.) exahust..this is a must!...i suggest 2.5 all the way back!..any larger for N/A would just rob your lower end..E.) Last but not least..springs and retainers..must have.. and valves if ya can part with the coin..F.) head,main,rod studs...arp or whatever.

with all the additions listed it would be possible to get 180'ish hp...from there its tweeking on the razors edge to get to you goal...hope this gave ya some insight.

yeah, those are all good info,hhmm but you forgot to mention the stock ecu being able to keep up with the cams, and lets say bigger injectors and retuned with everything else.would this work instead of a standalone or engine management.

[locoluna825]

yes you can have the computer reprogrammed to the cams and injectors. it would come out nice.

I threw a cold air intake, light performance cams, headers, new underdrive pulley, these new things called PULSE PLUGS, an electric fan, walbro fuel pump, aluminum fly wheel, ACT clutch,aluminum one piece drive shaft, and 2 1/4 stainless steel pipping all the way out, high flow CAT and deleted the resonator. i have gotten about 35 horse horse power out of that and i still want to have the computer remapped for all my mods and im pretty confidant with the remapping ill get to to at least 50 all together.

i haven't thought about changing the injectors, a light street port to the head and 10:1 compression combined with all that it would be very nice.

to get the full benifit our of the mods man..you will have to go at least piggyback as i understand it..standalone is much better as you can controll everything..but its expencive..with the bare minimum you can piggy and controll injectors to add fuel where needed.

i honestly trie to stay away from that,i grew up learning about carbs,efi interested me but i woulnt know how to tune everything,and im DIY kinda guy.

[dc1984]

problem with that is your gonna need to tune for it, thats just the nature of the beast. there realy aint no way around trying to fix it up and not tune for it. atleast not that i know of.

[98frontier_islander]

true,tuning is key,is there something out there at least to make me get familiarized with tuning,be it na or turbo?

[98frontier_islander]

also as far as reliability, my car is my baby and not like others who build it and then sell it eventually i want it to last,in the long run would a all motor dd last longer than a turbo vehicle,also which would be less expensive after everything installed?

[dc1984]

u mention u would want to tune urself, that makes it kinda hard. the only way i could think of u being able to tune ur car urself, would be for u to hook up one of the many tuning options and realtime data logging into ur car and then u would just be able to record a pass on the freeway/track and do it urself. other than that, any tuning would need to be done on a dyno, and if ur gonna be paying for dyno time for tuning, u might as well pay the tunner to tune ur car because the price probly wont be any different.

first thing youd need to figure out is if ur willing to pay to have ur car put on a dyno everytime u need to tune for something, or if u want to try to learn how to tune urself and do it with with some sort of data logging on a highway/track. ( i recomend using a track, much safer for u and others. and its legal)
