sorry to burst your bubble but your not going to even come close to 250 crank hp with that setup. Maybe 180-190 with all supporting mods. I hope your going itb or some kind of short runner setip. My good buddy had a ka built at Grigg's Racing for offroad use, with 12.5-1, a ****load of head work, schnieder custom grind cams, worked crank, rods, ng conversion, he made like 210 hp. 7-10 hp of that was from the ng conversion. Its in a 92 4x4 hardbody, he crawls at alot of events, its caged and nasty, he said it was in ORE a few months back.

id put you at as high as 190hp at the crank with that setup.

[neverlift]

and stup

way more has been done and less achieved.... I say go for it and let us know tho. Make damn sure you tune it good,stock can gain around 10hp...

[Bigvinnie]

Your going to need an engine management system and a short runner manifold to make those HP numbers. But the flow chart looks excellent, I know people that use the super tech valve train, it's good stuff!!!!

[artemous]

Nice looking ports but what about thoes nasty edges in the combustion chamber around the valves. I'm betting that unshrouding the valves would help a bit more.

As for input, Coat the combustion chambers, pistons, and exhaust ports with appropriate coatings, Swain or some reputable company. Run total seal Plasma moly ductile rings (not some generic junk), retard the intake cam a couple of degrees (reduce overlap and shift hp up a few rpms).

And honestly, run a thicker head gasket and reduce your compression. Your trying to run high rpm parts (compression and porting) with lower end parts (camshafts and shrouded valves). My experience adv. ignition timing brings torque and compression brings hp. Which one do you want? Trying for both will only leave you annoyed. (unless you run 100+ octane)

I'm agreeing with the 190 numbers for hp, but adding a note that I believe you will have a very narrow power band and be totaly unhappy with the current set up.

Get some better cams, those S13 cams are going to severely limit your output.

No point of having a head that can breathe if you don't have the cams that will allow it!

[Bigvinnie]

Brian Crower cams stage 3 are the biggest bang for your buck cams!!!!!!!!

[SimpleEnigma]

Won't he have to flycut those 11:1 CR pistons in order to make room for the large lift those stage 3 BC cams provide?

[Shift_Kouki]

Is he going to lighten his crank and rods? I mean while he's at it, I figure he might as well.

[Bigvinnie]

Yes he would, I forgot about the SOHC pistons being to raised. Those stage 3's work better with clover leaf welded heads.

well that is not even his head. that flow bench sheet is my head. it says ka24dett.

here is link to what he does for ppl.

be aware.

makes me rough about his work.

[teambuiltnissan]

he sales alot of KA stuff on ebay as well under the same name on here...

just be aware of him

So would this be your work or his...http://cgi.ebay.com/ebaymotors...ZWDVW

[teambuiltnissan]

that is the same picture I got from him.. except flow number are different. however, picture is my head. I doubt he can make exactly the same head. since his port job is pretty rough as you can see. couple of other member are complain about roughness of the porting job.. therefore, even if you buy this head from him, I doubt you will get the head exacty same head like mine. also he is selling longblock that is my flow bench test, and picture of my head.. so I doubt he is selling those because I have them here.

some ppl went thru 2-3 head with him trying to figure out what is the world he did. because they put this PERFORMANCE head and somehow they have to take it back out because mahcine work on head is not even in spec, leaking this and other.

I am not saying dont buy his crap, its up to you guys but I wouldnt want buy anything from him after I went thru. 1100 for machine work and assembly.. now my motor is trashed.

What do you mean by rough? Was intake side sanded/finished with 80grit like it should be. Or are the walls out of spec and never been flowed on the flow bench????? From what I understand intake side is slightly rough. While exhaust ports are suppose to be smooth and polished.

Also looking at the flow data that head can't be used for KADE's only det's. The ebay add claims that DE and DET's can use it...... I highly doubt it.

[teambuiltnissan]

rough as mean as you pay alot of money for un-even ported job and not even surfaced the intake or exhaust surface.

I would assume reputable/real machine shop will do complete job.

on my cylinder head, I had to ended up buy brand new intake and exhaust guide ( which was about 250 bucks) and have them installed.

other customers head is same way like fully assembled head, where you can take the cam out, and wiggle the valvesprings then it has crap load of play in it. this is not a push rod motor or anything like that I dont know how he can even do anything about machine job.. everyone seems like ended up pulling the motor apart and replacing/or fixing parts after he finished the parts. everyone can do the same job if you have to take a part and fix it again. I mean that is not a professional job.. there is liek 2 -3 guys complain the same thing so must be something that he likes to do ...

[Brandon93240]

I think this entire thread is bs and should be locked. Someone is saying someone else stole their work and pictures, that guy hasn't responded since this other guy who can't type for **** called him out. Basically I wouldn't read to much into this thread guys.

[96nismo240sx]

I did all the port work and flow testing to my head along with teambuiltnissan's who managed to totaly screw it up after I worked on the R+D for 3 months. I've been building heads for a lot of people out there and so far this guy is the only one thats unhappy. I guess everyone else out there knows how to set valve timing...
