Just looking to see if any other stock nissan injectors fit the sohc setup....

Basically I'm just toying around for academic purposes about a sohc KA-T because ive seen it done a few times by SDS, there is even a close to 300rwhp car from canada that road races all the time...


It'd prob be a microtech (deal that marksaccord is using) or SDS setup, low boost torque monster style, it'd prob be lots of fun even if it was ghetto... like a T3 setup, turbo from a Z31 or something.


Its def not SR, and if I really wanted to do soemthing 99% chance i'd go SR. But for some reason lets say if insurance was an issue, and or I needed LOTS of spare motors, sohc KA-T would be interesting..

 

sohc's use top feed injectors, so all you have to do is drop in some DSM 450cc and you will be good.

check the impedance across the stock injectors. if it is high (8-12+ ohms) then you will need a honda resistor box installed. if it is low, (2-6 ohms) then you can drop the dsm injectors right in. You could also run somethin glike msd72# if you erally wanted. Just find the right o rings that make both sides seal perfectly and you're ready to go. Also an injector clip change is probably necessary, but maybe not.

Good luck finding a head gasket and all that for a sohc, there's a good possibility you can use the DOHC head gasket that is metal by cometic for it, as well as using the ARP head studs for it. that's what you really need to do if you're going to boost the single cam.


Why waste money with microtech ?

Get a DIY Megasquirt system for $200 or so , and have taylor make you a harness for it.

 

MEGASQUIRT! Thats WTF it was!!! I couldnt remember for the LIFE of me what the cheap one was last night while i was making a list of stuffs.

Thanks for the help matt, I appreciate the straight badass reply

 

oh yeah, since megasquirt dosent do ignition, what will I need for that end of things (if anything)

 

MSD ignition with like a advance/retard knob like SDS?

 

actually i found a product called "megaspark" that works with megasquirt to give u full control... possibly I could get away with $600 or less for management.. so lets see...


also.. anyone remember the website with the KA24E turbo manifolds...

 

Old KA powahs here

so.. cost tally. Goals are just to have proper tuning and excellent cooling so that this car can take a few trackdays at sebring and not start detonating to all hell after a few laps.

Megasqiurt = 200-750 after wiring and depending on accessories and sensors and stuff
Manifold = 250-550 or so depending on log style or runner style
Clutch (spec 3) redrilled for KA = 400 or so?
walburo = 120
FPR = already own but if its broken then 150 + 15 for lil gauge
MAN Fuel Filter = own but if broken then 150
DSM injectors = 200 or so max?
Exhaust = 80(straightpipe)-380 (megan racing) - 450 (apexi)
Downpipe = 150?
Boost controller = 200-300 profec B or B spec II (gotta play it safe)
turbo timer = 100 (being safe as I can
MAN RADIATOR AND FANS = 400-500

Now for turbos I have a few options.

Used Z31 T3 for like 50 dollars or free
Used SR T25 for like 100 prob
Possibly a T3 T4 of some kind, but now price is going way up
Disco potato (lol more of a joke, but Scott did say it might do better on KA than SR, but more money than I wanna spend) 1250
S15 turbine (this sounds really fun and aabout 500)

so most expensive parts i can buy will run about 4135 (using S15 or T3-T4) or so. On the cheaper side of turbos, exhausts, and only running the fuel controlled megasquirt I am around 2350. Add the spark control and maybe 2500? So after guages, misc parts that act stupid and other things 3000-5000 is what i'd spend?

You cant get a basic clip swap anywhere for that. I'm not out to beat SR's, that isnt my goal. With an SR I wanted to have 300whp daily driver that is safe, reliable, and can be track day'd and drifted. That would cost me at least 8K with a blacktop to get it perfect.

But considering most SR's for 4400 or so have only sidemounts and basic swap components, I can see both of us for the same price making 200-210whp? maybe? Plus I dont have to worry about the law or insurance as much as an SR (a moot point but valid). Replacement engines are easy to find for SOHC KA, I'd prob run really low boost and be building a spare motor on the side for educational purposes.





OK gurus, what am i missing (besides labor)... Go head and stamp hard on this one, I'm not trying to beat an SR for ultimate power, but I think I can get the same reasonable goals for cheaper. If I want to get into the 280 - 300whp range I'll be hitting the line of where the SR is cheaper, but I really wouldnt have to go that far to have fun with the car, even 200whp would be lots of fun compared to 118-125 or so LOL

 

THE BLUEBIRD 370cc INJECTORS ALSO WILL FIT THE SOHC's. I'VE ALSO BEEN THINKING ABOUT DOING A TURBO SETUP ON AN EXTRA SOHC I HAVE LAYIN IN THE GARAGE, NOTHING TOO BIG EITHER. SLASH IF YOU WANT HELP...I'm all gamE.

 

I think i'd rather have the DSM 450's for insurance. Thanks for the tip tho.

I forgot a BOV, prob will go TIAL just to be safe again.
and various guages so i dunno, add 500 to the total cost maybe

 

anyone know where a headgasket could be found for this? something has to be out there.. There are 510's with sohc KA's running 9's in this world so there has to be something.
