Need info about n/a - Turbo
What would i need to go from a N/A 90 rx7 gxl to turbo, i want to do this but i dont know what i need, i read in other forums that the manifolds dont bolt up so wht would i have to do to get it turboed. Would it be cheaper to get turbo accesories and bolt them on or buying a T2 engine and getting it instaled. plz let me know asap

There is an alternate method that i'm currently doing. Its more expensive but considerably easier.
you'd probably be looking at 700.00 for all the parts at least.
I wouldn't recommend this swap unless you have a good reason, example being, your motor is completely healthy, and not wanting to spend the cash on a turbo motor that you have no idea the condition of.
very delicate process and it requires careful planning, as you are turboing a high compression motor.

The best thing to do is buy a t2 engine with the wire harness and ecu thats what i did and my project is comming along just great and it would be cheaper to go that rout than to bolt up because the rotary is not a engine that you can just throw bolt on parts and go thats what makes it so great but anyways invest in a t2 engine try this website www.jspecauto.com

Only thing i dont like about that idea is that if you order an engine that is trash, your out that much money.
that place offers no warrenty? they could just be selling **** motors on purpose and your screwed. I wouldnt deal with that place =/

too much trouble to turbo a n/a in the end its not worth it because you r going to have a blown up motor w/ a turbo save your self a headace buy a tII w/harness pull it apart rebuild,port,misclaneous mods, and put back together. in the end if you go that route you will have more power and reliability.

Here are some things that I didn't read or see while searching about a T2 swap.
-If its a jspec engine, keep in mind that the ecu is on the opposite side, so your going to have to wire in your N/A harness or find a aspec harness.
-Make sure you get a reputable seller of the engine, mine didn't come with a bov, drive-shaft, starter, ECU, slave cylinder, and a MAF sensor.
If I could go back I would have bought a T2 or I'd have one badass 1G DSM now..
I guess **** happens when your bit by the rotary bug.
GL man.

screw all this conversion crap. The other day I saw a guy that threw a turbo on his na, he just had a custom exhaust mani with a turbo and a fmic from a starion turbo. He used pretty much stock everything(as in stock na manifolds) except for the stock ecu. He used a megasquirt to control it.

You should consider buying a T2 (the whole car) and selling your NA RX7 to make up some of the cost.
Or buying a full T2 swap: engine, ECU, transmission, driveshaft, LSD, rear half-shafts, sway bars, brakes, (5 lug if you don't even have that). And after it's installed and running, selling the NA parts you took out.
Anything less could end up being more work and more money.
However you do it, I suggest getting the money together in advance and buying all the parts you need at once. If you find and buy things as you go, you might change your mind before you found everything you need.. or get half the parts and find a good deal later on a whole setup and you'll have extra parts and wasted money.

In this case, I think a TII swap is likely the best bet.
However, done properly, a turbo NA setup will not be any more likely to blow up then a TII setup, and will make more power on the same amount of boost due to higher compression and larger port area (with much later port closing).

I found in seattle a shop with 2 complete conversion for na -> Turbo
They are JDM half clips with rear ends that have turbo axles and hubs and brakes and everything. One of the setups actually comes with a Tomei two way diff!!! He's asking $3250 for that one. It's a Series 5 turbo.
The other is a series 4 turbo with all the same stuff, but just a stock Diff. he's asking $2500 for that one!
PM me for more info!!
