t3/t4 turbo on a NA 6 port
Alright first off i'm not looking for people to tell me not to turbo my NA I am doing it, I'm just looking for all the info i need so that my car will be down for as little time as possible. I found a guy that said he will sell me a manifold that will bolt up to a t3/t4 flange. What type of turbo and wastegate would i need hat will bolt up, or be best off with, so that i can control the boost and not over boost? i'm probably looking to run 6-8 psi. I've heard that some older american cars came with stock turbos hat would bolt up and provide enough boost is this true? which cars have em?

I am thinking about doing the same thing to my car, but I would like to rebuild the motor before I put on the turbo. Can I get some help as to what would it take to make it with stand a turbo. Please help me out this is my first RX-7 and I love this car so far. Except for the dam sunroof.

You can either go custom, or move it out 2.5" (which you might as well just go stock with if you're only running that ammount of boost). I've got a stock s5 turbo strapped to my 6port block running 13psi with no ill-effects yet.

I'm with sonicrat here... I've been thinking long and hard about the turbo'd 6port, read a lot of stuff, thought some more, asked questions, read, thought, etc
I've also thought about a different turbo than the stock s5 with a custom manifold, but really, on an n/a block I don't think I'd ever hit boost levels to make it worth it to me to get a custom manifold made and a better turbo. The stock s5 manifold and turbo are plenty good, and if sonicrat is running 13psi with no ill-effects, hell I'm ecstatic, because that is exactly what I was hoping to run when I end up doing this.

My stock Series 4 N/A motor had a pretty customised T3/T4 turbo on it before I blew it up.
Had a custom manifold aswell, moved the turbo further forward (Series 1-2-3 style).
Went pretty hard.
Will be putting turbo back on in the next few weeks in a new high comp, big street ported 6-port motor.
If you'd like to see exactly what I did and what I had to change do a search for my username and 6-port turbo or something, i'm sure you'll find some good threads.
Will take too long to type it all out again here..

I'm paying 150 for the minifold if i get it and i was told it is a stock manifold that has been modified to fit a t3/t4 turbo, all i want to klnow is the kind of turbo that would work best for a turbo'd six port sumthing that will spool quickly too

If it's a stock manifold modified, it certainly won't fit unless they somehow extended it all out another 2.5". The stock turbo (s5) will spool by 2500rpm on the 6port, however the s5 is a bit tougher to fit.

i know i need the spacer and I will probably notch and reinforce the frame as i belive arron cake did, this is much easier than you all are making it. The guy has a stock manifold which he modified the flange on, maybe enve removed an weled a diff flange on that will bolt to a common t3/t3 turbo. I want to know what turbo with this flange will bolt up and spool early?

Simply relocate the wastegate actuator and use bicycle cable to actuate the wastegate. Now the actuator doesn't interfer with the inner fender/frame.

thanks arron cake for the waste gate relocation tip, and as far as being overkill i'm just asking since i found this manifold, and a freind of mine has 3 t3/t4 turbos one he said is a t3 drag ball bearing but needs a rebuild. what i'm realy looking for tho is a car that i can get a turbo from that will bolt up, since the stock turbo won't bolt to the flange

I'm a bit worried about how it was modified, it makes me think it'll stick out further, and as is, it's such a close fit with the stock that I'm kind of weary about the angles the other will sit. It might work better, it might not. That's the crappy part. I know my S5 just barely fit, and I had to hammer in a section so the rear exhaust housing on the turbo could fit. But my wastegate fit just fine after I cut the square edges off the bracket it's mounted to. I just think that if you maintain only about 6-8psi (basically you can just loop the wategate straight to the nipple on the stock turbo) you could be at this level for probably cheaper than the T3 route, and you know it'll fit since many people have gone that route. But regardless, if you go with the T3, be sure to let us know how it goes, saves other people from guess work!
