True that, just not something people usually paint, lol. Going to paint the intercooler piping as well? It is an interesting color contrast, he have any pics of the engine bay I missed?

Hey I have a set of TII side and center housings from my Tii that I will be postig for sale......Wanna buy them.
I have 2 sets. I'm using one set to put together a 4 port engine with N/a rotors for my 1st gen. Running it mostly stock, just fuel and boost upgrades but nothing major. My 87 TII is getting a nice Cosmo engine put in it with some big fat ports like a *****!!!! LOL
Your car looks like it will be fun and all but for reliability I would strongly advise spending $250 and picking up a greddy or HKS cast iron manifold........I have used them for years and Luv them.....
I used an SS autochrome manifold about 2 years ago and it cracked after 2 weeks. Got another one and it lasted a month until we went street racing on a cool night.......Don't get me started on OBX turbo manifolds...........Tried those on a honda and they just don't seem to last through the weekend if you push more than 12psi.........
Hey do a list of your fuel system!!!!
I wanna see what it's all about............
Peace

I'm starting to get a bit sick of hearing stuff like this...
Why? You can run whatever boost you want on high compression rotors as long as you have fuel and timing support...
Yep...But does it matter? Not unless you're running a high RPM engine. The NA oil pump is more then sufficient.
Since when? And can you prove this? Because the 6 port irons have WAY MORE port area then the 4 port irons.
Well, sort of. I agree that the NA manifolds are optimized for NA operation, and the TII manifolds are designed for forced induction. But the power levels of some of the NA-turbo setup would tend to prove that the NA manifolds are hardly a problem. It can either be less or more convenient for intercooler pipe, depending on how things are setup.

Don't get me wrong, NA turboing is a great idea, for those that just want turbo power. But seriously, for high HP applications, stick to parts that were designed with forced induction in mind for overall better reliability at that high of an HP level.[/qutoe]
Aside from the ports, the castings of both the NA and TII housings/irons are virtually identicle. The only internal change in the TII engine is the oil pump and baffle plate.

We can also tell you that the oil pump in the TII is better than the NA counterpart.
I can also tell you that the 4 port Irons flow better than 6 when ported.
I can also tell you that the manifolds for the TII are far better suited for an intercooler/turbo setup than any NA manifolds.

One reason the 6port is a 6port with different setup than 4port is because it's n/a! It needed more port area to make up for the fact it had no turbo, so they coule keep power levels a bit higher still. At least that is my guess on why they did it, otherwise what was Mazda's point? Wouldn't it have been cheaper to not redesign the engine and just keep the n/a motor with the 4port irons if they are supposedly better?

I think this may have something to do with people believing that with heavy street porting the 4 port flows better than the 6.

Intake: The 6-port non-turbo engines (made from '86-'92) are a totally different story for porting. The front and rear side housings have the auxiliary ports in them, and the center housing has very small ports. Additionally, there is not a lot of casting thickness behind the upper part of the center port. This means if you go too far, you hit the water jacket, and the housing is now junk. If the two smaller ports in the end housings are made into one LARGE port, it is WAY too big. Therefore, the end ports are not changed much, and the majority of the time is spent on the center ports.

Mazdatrix is wrong IMO. There is significant porting opportunity on the end irons of 6 port engines. People who claim otherwise probably haven't ported a 6 port engine to the max.

Oh god not this again, do you have one? have you even seen one up close? Did you even read this post? we just had a big talk about that about 2 pages back why must you repost abou this.

um... obviosuly people around here dont know what they are talking about. yes i have had numerous ones. and threw them all away. and yes, i have delt with ntoonly their manifold but their waste gate, their bov, and their turbos but this topic is like beating a deqad horse with a stick. o well. i dont care. youll get the same effect as if you made one out of bees wax.
other than that i hope it goes well for you. i was planing on dong the same thing then gas went out of controle.

Not to mention your going to need it running that much boost+HP.
Just my opinion, don't rag me on it, read it and disagree if you wish.

1. "Higher boost with lower compression rotors"
Response to #1. Proper tuning will allow high boost with high compression.
2. "We can also tell you that the oil pump in the TII is better than the NA counterpart"
Response to #2. I'm not sure what your saying exactly. Does the TII pump have more flowing capacity, pressure, rate of increasing pressure??? I obviously don't know, so I ask.
3. "I can also tell you that the 4 port Irons flow better than 6 when ported"
Response to #3. Proper tuning can allow even stock size TII ports to make plenty of power. It has been proven.
4. "I can also tell you that the manifolds for the TII are far better suited for an intercooler/turbo setup than any NA manifolds"
Response to #4. Sure the TII manifolds were designed for forced induction. Proper tuning will allow the expected power to be made. It could be tricky, but it is possible.
Sorry if this comes across as a personal attack. THAT IS NOT WHAT I INTENDED. I just ask questions.

I always wanted to post that to a troll though, jeffshoots is the man!

Oh and i forgot to say that i will be putting the motor in hopefully thur or friday, just waiting for the front cover gaskets and rear main seal and front trans seals and the RB 4 puck sprung clutch

You're not rebuilding it before throwing a T70 on it?
