^ Also what is the bore size of our pistons/cylinders ?
That will probally be one of the first things I need to know.

 

http://www.honda-performance.com/info-lv2.asp?id=366

forged pistons for the j series can be found there^

Do you plan on staying NA or boosting? You will need to resleeve the block if you're going to try something crazy like 3.5 + turbo... our stock cylinder walls cannot handle much.

I have an 04 odyssey crank if you're looking for a build up...

 

thanks for the link
I just want the lower end to be able to handle 150-175 shot run after run all day.
I'm pretty sure the block will handle that.
mostly worried about the rods.

Upper manifold and TB will be next in line for the pnp since I just located a type s TB.

 

sweet. but whats the compression ratio? and what kind of ring can be used? oem?

 

The vavle train set up will work on type s heads ?
It don't say how big the valves are. Looks like some people will be calling them.
Now we need to locate some sticks for a decent price.

 

A 3.5 can handle 10psi. Its when you start going for the really crazy build (3.7l + any kind of forced induction) that it goes boom.

 

hahahah like a mazda... ZOOM ZOOM BOOM

like my probe with a KLZE in it...

 

SWEET... finally some lovin for the j series, never heard of that company though

and othe performance parts are on their site for the v6

 

No PnP updates but,the headers showed up.
They look good but,I think inside the header where the 3 pipes are welded could have been cleaned up a little nicer.

TB hopefully will be here tomorrow so I can get some more PnP in.

Still waiting on the injetor base gaskets so I can open up the lower holes on the runners and match them to the heads.
I seen some one selling some in the BM and their going to open pretty large.
Once the gaskets are here manifold is coming off and getting done.
Also I think the header install will be much easier without the manifold there.

 

Damn, so shiny! I'd like to see some gains afterwards though

 

what headers are those?

 

I'm sure there will be a few found.

OBX

 

Got a type s TB today.
So I started on it but,ran out of sanding stuff. The TB plate is also knife edged.To help with flow.
It don't look too bad,I might go opening it up a little more.



Also started on the spacer.
It's trimed,and I polished 3 holes so far.
I'm going to make this piece look show quality.

 

what's that orange stuff towards the right in your tb, almost looks like high temp rtv sealent or something, but don't see why you be using it though

 

polishing compound

 

fair enough, did you do it with the plate still installed or disassembled everything

 

Plate came out but,there was no need to remove shaft and assembly.
Throttle plate was also thined and and beveled at the edges to reduce drag.

 

so it is still the factory bore just the casting marks on each end were matched with the fatory machining for the thottle plate ???

also throttle plate thinned??? like you put it on a belt sander or something to make it thinner , cause the 1 thing i be worried about it being too thin would be when you are under high vaccum (engine braking) and it collaspeing/bending inwards, then it accelerates when in realality you are wanting to stop/slow down

 

Factory bore where the plate is yes.The inlet and outlet are a little larger and all bad castings are smooth.
It's all good,The plate is thiner the last 1/8" to 1/4" .Then the back side of the blade is beveled so the rushing air will flow easyier than going over the blunt edge that was there.
I put up pics of the blade after.

 

Throttle blade, The TB is farther along than this.


Close up to see beveled edge on blade.
Again tb is further along than this,
blade is fully buffed now.

 

if its possible. id rivet in the plate instead of using them screws which can mess up the air flow.

 

I was actually thinking of thinning the shaft to picking up some more but I don't know because it might take away from the strenth.
might just try to blend the sharp edge of the shaft thou.
Quicker throttle response soon.

 

or you can be like nissan on their VQ35 engines with drive by wire (~01 to 06)(especially the car ones) where they put a tsb out about the throttle plate screws backing out and going into the engine, you know the end result with them not always warrentying them, so i would loctite them in place at a minuinum (spelling?)

yeah i proably would just smooth out the edges

 

I don't feel like messing with it anymore.
This throttle body should perform well the way it sits.

 

Did you get a new throttle plate to seal it up? If not, you may have idle issues due to air getting past it.

 

still factory bore, so new plate not really need, just the rounded edges might not seal as well, but by the looks of it, it should be alright

 

plate is perfect.
The od of the plate was never changed.
If you look at the pic above you will see I left 1/3 the thickness and tapered off the back.
It makes a perfect seal doing it like this.
also reduces on drag

 

Ahhh, I didnt read it, I thought you bored it.

 

so I was board about a hour ago and took the manifold and throttle body out.
I took a pic with the mdx spacer sitting on the manifold to show how much will be getting taking out of the manifold holes to port match.
This manifold will flow crazy when fully macth port and polished

 

nice. but wish u can do some before and after dyno's

 

little too late for the before and after's.
I'll let everyone know how it will perform from behind the wheel.


I want to get the plenums off to work the whole intake.
Is there reusable under them ?

 

If you are worried about the shaft, you could always throw in a little [epoxy of choice] to smooth the transition from the throttle plate to the shaft.

 

stripped and cleaned the manifold today.
and only opened up the TB inlet to match the type s TB.
maybe I little making it larger and when it goes threw finishing steps it will be perfect.

every passage in these manifolds has a overlap.
I cant believe how bad the passages are lined up from factory.

 

reusable maybe, but they are metal gaskets under the plenums like the lower one (next to the mdx spacer), so kinda your option i guess

 

you also gotta remember they mass produced our engines, so you gotta give them some leeway, but yeah i thought honda would be able to do it better than what i have seen on mine

 

here's another pic
TB inlet opened up a little more. everything is rough,tomorrow everything should be looking good.


This is a pic from inside the runner to see if the TB is lined up.


Tomorrow the rest of the manifold will be completed.
I finished the spacer tonight.

 

You could be in for some trouble doing that man. You may end up with a high idle. Its your can and do as you will, (I know you will) but messing with that butterfly could be bad news. Myself, I would not have done that.

Hope it works out for ya though.

Everything else looks good!

You might be able to ge a few video screens into the top of the manifold???? J/K!

 

Did you remove any material from the TB where the butterfly sits when it is in the closed position?

 

^no he didnt. thas why its gonna be all goo.

 

^ x2

here's a pic of the manifold matched to the spacer(in the rough).
