I have a N/A motor that is in good condition and I want to a build a turbo motor with it. I have all turbo manifolds and front cover for turbo oil line return. Do I need to change irons and rotors housings too or do I have enough to build the motor? Can anyone help with some technical advice or experience with this build?

 

See 2nd gen FAQ, engine section. Port matching the lower intake manifold and getting oil feed/drain locations are the major issues.

 

yeah the FAQ has the answer u need, but as for the oil feed and the front cover u can tap into your oil pad for the oil dump and racing beat sells a sandwich plate for the oil pedestal u can use instead of tapping into your motor for the oil feed, i advised you to make sure the oil pressure is restricted some how and not run actual engine oil psi... again the faq has many different threads that you can view with everything your gonna need for technical q's
good luck

 

aaroncake has an awesome write up for port matching the turbo2 lim to 6 port n/a block

Can I swap a Turbo engine/Jspec engine/13BT/etc into my Non Turbo?
Yes, check these links:

How do I add a turbo to my NA 13B?
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:

Ok so I basically have a N/A block that runs I have acquired the tII irons all the intake manifolds and exhaust manifolds from an s4 tII basically is only b reusing the rotors eccentric shaft and rotors housings from the n/a block will I b able to use the tII stock ecu? And can this work or do I need to change rotors too

 

y r u taking this running motor apart? just slap the turbo manifolds and accessories on the thing..

 

Do not use any stock ECU if you're building a high compression turbo. It's not worth blowing the engine because the fuel and timing maps are nowhere near safe for it.

 

You're building an engine with compression 1.1 points higher than the factory turbo, so the stock ECU won't do the job.

The easiest thing for you to do at this point is to just build a TII 4 port engine, using the TII rotors.
