Rebuild N/A to Turbo questions!

So I need to rebuild my engine. 86 GXL so its 13b N/A 6port. I have a turbo in my possession that is a t3 flange. U know what im driving at . My question is, can I rebuild my N/A block with stronger parts to handle some low boost? I bought some 3mm rotors off a guy on here already, should I be using T2 parts? Is that even possible? haha If there is a big thread on this subject I would love to see it so I dont have to bother u guys with questions undoubtedly asked hundreds of times...

those NA rotors have higher compression, which is typically not ideal for a turbo. get some turbo rotors. Than tap the according parts for oil and water for the turbo.

aaroncake.net would help quite a bit I think. If I'm not mistaken, he ran up to +10 lbs on a stock turbocharger, which is pretty good.

Copied directly from the FAQ:

What Turbo kits can I add onto my non turbo RX-7?
There are no longer kits formally made at the time of this post, however there are companies from time to time that do make available non turbo to Turbo Kits. Because most of these companies stop building the kits, or go out of business in short time, it is impossible to keep active links for them.

Most people that turbo a non turbo make their own kits:
Using the stock TII turbo, exhaust manifold with spacer, NA intakes and NA ECU:

How to use the TII lower intake on the NA block, which lets you build a "6 port TII" by bolting on all the stock turbo stuff:

"Turbo with a T3 flange" means nothing really. T3 is just a flange size and range of turbine housings. But it is probably too small.

A 60-trim T3 compressor wheel pretty much the same thing as the compressor on the stock turbo (inducer a little bigger, but exducer a little smaller). And the turbine side will almost definitely be too small since it was intended for a small piston engine. In other words a stock turbo would be a better route.

Compressor chart: http://www.fc3spro.com/TECH/TURBO/tmodels.html

More important issues are: Fuel injector size, fuel pump and what you're going to use to control it. If high compression rotors stay in, An Rtek 2.x or standalone will be the only safe ways to go. If low compression rotors are used, you could get away with a TII ECU, SAFC and FCD. If low compression rotors are used, and you keep the boost at ~8-9 psi or lower, just a TII ECU could be used.

Way too small.

How much power do you want to make?

The stock turbo is only a valid choice because it is convenient and cheap. Other then that it is an inefficient 40 year old POS.

Well I'm rebuilding it now with streetported irons and 3mm cut rotors removing emissions with dual exhaust hoping for 200 at the crank...if i go the turbo route i dont ever want moar than 300 at the crank. So prettymuch a relatively easy/cheap build i hope?

Why are you using 3mm apex seals when the 2mm apex seals should be more than adequate?

Got a great deal on them and It seems they would provide a little better seal and miniscule increase in compression ratio

I'm not sure about that they seal better, to be honest, I heard the reverse, but if I recall they are durable, which I think is the only thing going for them. Can anyone comment on 3mm apex seals.

3mm apex seals are more durable but create a worse seal. The conversion must also be performed correctly or you will jeopardize your whole build.
