Oh bless you!

i dont know if it was because it was soo corny but it made me laugh soo hard...

one quick question tho... what was the whole purpose of the pair valve? from what i read its just to cheat emmisions tests but i dunno if it served any other purpose.

It's to allow oxygen into the exhaust system before the catalytic converter while the engine is warming up and under deceleration. This oxygen helps the catalytic converter to burn off the excess fuel from the very rich startup map and also from the excess fuel on deceleration. It is a check valve so it prevents exhaust from backing up into the intake.

alright I need some info from Diaz,DV8,Kenso and others...

I will have a 3.5L shortblock in two weeks to tear apart. I have a type1 block totally apart already. I have another type 2 in chicago...

Now I am doing this 3.5L on a lower budget since i have to get it running by march 31st and it will be put in my red coupe(daily driver).

I planned on having the type 2 heads done in chicago with a 3angle valve job...and then slapping them on the 3.5 like DV8 but with a more custom manifold and then throwing cams in later.

HOWEVER, i have type 1 heads sitting on a bench already so I was thinking to make things go quicker for me and easier I could have the type 1 heads milled down and cleaned up and put those on. My thoughts though are how much of an improvement are the type1 heads over the RL heads????

I also am NOT getting headers and will be porting out the exhaust manifolds...but then DV8 stated he thought the type 2 exhaust manifolds were somehow better???

I plan on building a custom y-pipe however.

So I guess the question is whether it is really that big of difference in the cam profile and heads of a type2 compared to type 1.??

The reason I am discussing this is because the C32 i have torn apart is where all the money is going.....so should i invest the type 2 heads that have the 3angle valve job for later on this engine????

I have two months...got to act fast.

I remember when you were anti 3.5.

I would use the RL heads, then you can use any intake manifold of your choosing. The RL and Type I are practically the same, while the TYPE II is better. How much better, is anyones guess-maybe an extra 10-15 to the wheels. The manifold isnt the only thing that will need to be custom if using any other head other than the RL. The manifold water passage does too.
Ultimatley the RL head with any manifold, TYPE II valvetrain, and webcams would be perfect. Machine work would be involved.

I am anti-LONG BLOCK 3.5 and the way you did your manifold. That is it. It is a very well designed block but like I have said my money is going to my C32 blocks and this is going in my daily driver.

I just am trying to figure out the fastest way to do this.

Ps-jason at AoA is kickass.! He remembered your header project.

I am only getting a 3.5 short block hence why i cant use rl heads...

Mike Diaz · 02-06-07, 09:48 AM

There's nothing wrong with RL heads. Especially the fact that there are a lot of low mileage heads around for the picking. I'll make up for the difference between Type I and Type II with my cam profile. Nothing better than knowing my engine has 200,000 miles less than the car has.

Out of curiosity, besides the extra work involved, what is your reasoning why you dont agree with the way I did my manifold?

If you need a car up and running, why dont you just get a JDM motor and do a quick swap. Sounds like the easiest and quickest route to me.

Type II valvetrain revs higher naturally and looks to me to have more rigitity with the two extra rocker bolts. Once a pair of cams goes in, the engines going to want to make power through 7k. The RL valvetrain should handle it i just dont know how well and for how long.

We'll find out next summer. I plan on sending them out this weekend after I get the money from this head gasket job.

Block-$400
type 1 heads-free
manifolds-Two spare type 1s

If i am honing and doing rings..might as well do pistons. But ....why would i do that to my C32 which i want to invest more effort in. Why use my type 2 heads on it or type 2 manifold......or swapping cams and valvetrain over.

I had a type 1....3.5 is better....3.5 type 1 hybrid should be better yet?? and more reliable and i can do it just as fast.

Good jdm with 60k is $800 plus shipping...

With all the effort you put in your engine you didn't put that same amount of effort in a good intake design. just my two cents.

This isnt a good design?

I would be careful with how you word things since you have absolutley nothing to show for and still dont. To me you have zero credibility Ben. Everything you think of doing, you post on these forums for others opinions instead of doing them. That tells me a: You want attention. B: your not 100 % sure yourself of what your doing or if it will turn out well. I like the chance your taking on the pistons, those are the sort of chances one takes for the benefit of community, but to comment on a design were one has no basis, no foundation or credibility other than "I dont like it" is like a child not liking a certain flavor of ice cream-why? Because.....

Dont respond to this unless you give me real reasons, technical reasons and then show me proof to back it.
Granted its not a custom manifold; I can find better ways of spending a few g's.

Mike, hes calling you out too since you did the same manifold setup I did.

You know what I didn't do? I did everything that you did, except for filling in the top so it would be smooth. What did you use?

I don't care what anybody thinks about my engine or my car, I know it's a fucking blast to drive, and a lot better than any 3.2L out there.

Funny, I just pm'ed you. Marine epoxy.

I'll have to grab some. My manifold is out and on the bench.

This will be the third set of intake plenum gaskets I bought in the past 6 months. The local Acura parts guy is going to think I'm an idiot.

Take pics of your progress and pack that epoxy good. Those gaskets hardly go bad, cant you reuse?
