We are starting with a 260 hp Acura 3.2 Type S motor.
I think the motor put's out somewhere around 220 to the wheels in it's stock form.

Day I got the motor:

Sure! That is a neat looking engine. It looks like it was in excellent shape when you tore it down. Any idea on how many miles it had on it? Clay

It had 110k.
And with these engines people do a major service at 105k,water pump and timming belt and timing componets.

When I pulled the engine apart the water pump looked brand new and the timming belt and t belt tensoiner only looked like it had some dust on it so I assume they took care of it and had that service done right before I bought it.
It came out of a rear ended car.
Got a pretty good deal.
Funny thing is when I picked up the motor I was only going to by some valve covers to repaint for the motor I already had.
I get carried away frenquently,that's what the acura website has done to me and being car crazey does not help either.

I can't find any before's of the intake side or the exhaust side off the heads but,this lower runner picture is the same size as the head was before. I had to even retake this picture of a already developed picture so I would have atleast something to compare to.
I have gasket matched and opened up everything as large as possible.
If you look at how the gasket sits at the top is where the injector comes into each chamber.
[img]
here's the intake side of the head all but blending the last area right before the sit looks done.
These are old pics to me so the description I'm giving you is by looking at them my self.

[/img]
Here is one of the lower runners
[img]
[/img]
Here's pics with the lower runner against the head just balancing it there to take the pictures,they are not tightend up but they match perfectt when the are bolted together.
[img]
[/img]
This is a 2" Manifold spacer from a mdx that was opened up larger for me.
matching to the other side of the lower runners.
before



[/img]
Same side after
[img]

Other side

In the rough after

A couple more manifold pics
I don't have any before pics of the horns but they lined up really bad with the manifold.
[img]
And if you look inside at the butterflys they had flat squared edges in front of the blades
[/img]
I have a couple of internal mods that others dont ,I will show one.
Now if you look at these pics I have made wide mouths that will help with the flow.
[img]
[/img]
[img]
Some TB work, before
[/img]
Opened up the front
[/img]
Cleaned up the back side too. Took out all casting rings
[img]
Tappered 2/3 of the TB blade for better throttle response.
Showed another one of my little extra's
[/img]
Matching the TB to the manifold,in the rough
[img]

More later.....[/img]

1971 Chevrolet Chevelle

Looking at the block if this is an all out effort engine I would look into the weld in deck plates. The cylinders are open at the top with no support. I have seen this done on high end Honda builds in the past. I have been trying to find a pic but have had no luck. Basically the plate fits into the gap around the top of the cylinder in the deck. It can either raise the deck with sleeves or weld into the deck as is and have it milled after.

This was the best I could find but it shows what I was talking about.

I will be going all out beside using billit forged lower end.But,the lower end I have is a factory forged rotating assembly so it is better than cast pieces and the pistons do have coating on the tops and skirts.
I really don't like downloading files from forums but, If your talking about making a semi closed deck to prevent cylinder walk this is what I will be Exactly going with.

That is what I was referring to. The file is a pdf. Not a virus. Besides if I put a virus up here smoke would kill me.

Ok guys I'm about ready to start on the build.
Took a break because I got tired of collecting parts and not seeing anything new with the car.
I went on a little lighting kick since my last post.
I got a
CF hood
CF trunk
light weight seats
light weight battery
got rid of windsheild washer stuff
got rid of frame dampers
and added full CF di noc interior trim pieces
and weathertech rain visors
So I have been doing things but,just got tired of buying engine parts to just sit.

I have my pistons,rods,and rings assembled now so I'm ready to drop them into the block.
I just need to get it cleaned and pretty first.
