I don't think there is any gain from swapping those heads. But you are right TURBO is the way to GO GO GO GO!

 

I've got -
11.6:1 CR pistons
Total Seal rings
Port/Polished head
Shaved Head
Garrett T3 (about 5 psi, just a little)
FM Intercooler
NX Wet system (50 shot)
Downpipe back exhaust (Fake cat with straight-through muffler)
294 Cam
ECU Upgrade
370 Injectors
Front and Rear Upper Strut Bars
Rear lower strut bar
Lowering Springs
16" Borbet Wheels w/ Kumo Ecstas
CF hood
NISMO Style Body Kit

Various other CF parts i've made

 

Sounds really cool road kill. Have you dynod or ran at the track with it, What exhaust manifold are you using? SOunds really cool.

 

As you read from my other post, the motor is in the process of being put back into the car. The cams have changed to a 300 duratino and .507 lift from PDM Racing. I decided to do the super charger instead of turbo. I actually built my own manifolds. I built the turbo one for the T3, then i decided to do the super. So then I built a 4-2 header and am planning to run dual exhaust. Or I might just do a single, then they would be 4-2-1. My company may start building these to sell because i know there aren't any turbo manifolds really out there for the KA. I wanna see how they work before I start selling them, I dont want to sell crap. We may strat selling a head-back exhaust system. I want to wait untill i hear mine. The muffler, if i do a single, is made for a Corvette C5R. It sounds sweet and since the corvette is a dual, I think that the KA will make it sound almost the same, so I will just see.

And when this motor is broken in. DYNO

 

a supercharger????? since when could we fit one?

 

Since i made room

I've removed everthing but the waterpump and altenator.
The fit really isn't to bad. When I put the motor back in, I'll post some pics.

 

what kind of supercharger are you using. and i would love to see pics of this setup

 

me too

 

i dont have any real hp numbers for you guys but the dyno in my seat read improvements with each part.

injen intake, 5zigen catback, hotshot headers: if i mashed on it at about 3grand in 1st, it would break traction then at redline i would grab 2nd and it would keep spinning til 5grand when the nittos would grip and i would bog like a champ

then after awhile my clutch started slippin... so i cant do it much anymore

not too bad for s14 with heavy *** 18s and nittos

eibach sportlines, luv em, trust front strut bar, nice and stiff

 

Well, I have a Fast 240 as well:

Catback 3"

I've been wondering about that whol skyline motor swap. How do the rb25's fit in the s13's?? Do they drop in or do you have to mod the mounts?? I would love to drop one in, i just dont have the time right now.
