i have an 88 rx with the 13b n/a in it. im trying to figure out which way to go with this. should i rebuild and reuse or buy a 13bt and build it. im in ohio and i dont live that far from rx7store.net so i have a shop i can deal with pretty close by i would like to get some input from some people who have done the swap who havent done the swap you know both side's. im sure this topic has be over descused but i just spent 4 hours looking for the anwser to these questions and nothing so here it is. thanks

 

depends what you want to d with the car. And if you are dead set on the turbo motor why don't you just sell your NA and buy a t2? Save alot of headaches and some cash.

 

Buk is trying to tell you that the TII swap is a mojor PITA.. especially if you have little or no experience with RX's.... By the time you get done buying the parts, you could have had a running TII if you sold your car!!

Get the Bruce Torrentien(sp?) video and take a peep at that, rubilding a rotary is actually pretty easy, but its time consuming and messy (lots of cleaning involved) and you do need a couple of special tools to make life easier.

Most guys on here will jump around like lunatics at this suggestion.. but, why not just chuck a 302 in it??? Cost a lot less than doing a turbo conversion!!!

 

i want to try and drift but who doesnt these days. i dont want the turbo 2 dont want to mess around with the sequencels dont think i spelled that right. just want a single turbo. 302 would be fun but i want to stay with the rotary motor. and i have no idea about the damn thing. but i figure what the hell and try and build it. would it be easer if i turboed a non turbo motor or would i be pissing into the wind??!

 

The stock S-4 and S-5 turbo motors are single turbo. The 13b-REW (third gen engine) is sequential. So you get single turbo if you stick with a FC engine.

 

if you want performance than go t2. if you want reliability than go n/a.

t2 swap is costing me $5k. i know i could of just bought a rx that is already t2, but you don't learn anything when you do that. sides, i got nothing else to do, might as well mess with my car.

 

Have the motor rebuilt put all that extra cash into suspention and rebuilding the suspention assemblys bushings bearings mounts and all that.

 

What he said. Rebuild, give it a nice streetport. Make it handle like a bitch with all the money you saved from not going turbo.

If you have a second car to drive, I'd say give rebuilding it yourself a shot. I'm in the process right now. I don't know all that much but I have a general understanding of how it works. To say the least, it will be a learning experience.

 

i got a truck so rebuild wouldnt be that bad, how hard would it be to turbo the non turbo motor. i know i would have to change my fuel map and probley my ecu. fly wheel and all that jazz but i was going to do that stuff any ways. im trying to figure this out i got money to burn and all kinda things i want to to do

 

You need lots of stuff to turbo an N/A, not the least of which is a standalone ECU. There are several threads around about it, including a great writup on aaron cake's site.

 

You can buy a j-spec turbo engine for about 900 with shipping. and the whole swap will cost you about 2000-3000.
we got ours done with 2500. we had to buy everything, whoever in japan, that had the engine, had ripped out everything from the BOV to the clutch.... but it still only cost us 2500, used the stock wire harness and got ahold of a turbo ecu *n37X*
so it wasnt too bad.
