TII swap

[TokyoDrifterxo7]

I have a 86 rx7 na and i want to get a turbo motor in it. i was wondering if anyone knows of shops in so cal that can do the swap for me. if so how much would that run me?

[Cobra_R]

well, i dont live in socal, but my advice would be to check the phone book and just look for a place that specializes in Mazdas, the swap isnt something that needs to be done by a rotary shop, its farely straight forward. just look for a shop specializing in mazdas....or ask on rx7club.com.

[nasty nate 7]

why not just do it yourself? youll learn a lot, im in socal area and most of my friends are rx7 buddies. we're also on the forums too

[TokyoDrifterxo7]

i dont have the means to do so. if i did, i would be doing the swap by myself. where in so cal are you? ever done a TII swap?

[s13daver]

t2 sway is much more work then a normal turbo motor swap, you have to swap out all the drivetrain with t2 drive train(tranny,diff,driveshaft).upgrade fuel pump, something with the dash harness you have to do i think.i hope you did your homework on the swap.

[TokyoDrifterxo7]

yeah i read all about it. i wanna get a price quote on it to see how much it would run me. if it is too much im just gonna sell the car and get something else. not quite sure at this moment.

[nasty nate 7]

well lets see, you need the rear end, tranny, driveshaft, might wanna change engine mounts, the s5 or s4 T2 wiring harness and the block. if you go to a mechanic alone, id say they'd charge you about 1200 to do labor(40 dollars an hour at my mechanic). rear ends are worth about 150(tops), trannys go for 250 - 350, wiring harness uncut will cost about 70 - 100 bucks, blocks will cost you about 1200 -1300, engine mounts around 50 bucks brand new, driveshaft about 30 to 40 bucks. parts alone will cost about 2k. so id say get rdy to spend about 3200. the good side to this is that the base models are lighter than the turbo models. you can have your own race bred car
im in the 626 area

i heard if i have an S4 its best to stick with all S4 parts. im kinda having second thoughts on this swap. I really want a turbo but could save money by getting my motor ported and rebuilt and just add a aftermarket LSD. Upgrade the tranny for the abuse i put it through. i have the money but i heard so many bad stories about people getting bad engines and they blow. i dont wanna get screwed. but for sure eventually i will go turbo. i guess i could hold out on the TII swap for awhile and just get NA upgrades and see how i like it. anyone know the HP potential of a NA 13B? i wanna push around 280-300hp to the wheels. possible for a reasonable amount of money? and is it daily drivable? get what im sayin?

[Cobra_R]

you really cant get 280-300 hp out of an NA unless you do a huge port like a bridgeport, plus tuning and other things. if you look around RX7club.com, most people are having trouble getting to 200 on an NA...one thing you could do tho, is turbo your NA. but youre gonna have to find someone who knows how to do it. which i doubt you will, but you might. i kno someone who could do it, but he lives in walnut creek.

if youre tuning your FC for drifting, you might wanna just spend money on suspension, get a rebuild, maybe a streetport, couple other small things...but 280-300 on an NA is almost impossible, you could do it, but it wont be smoggalbe and would cost a furtune, and i doubt it would be a very good daily driver.

the n/a motor of the rx-7 could handle probly 200whp with out a rebuild. my friend is going n/a on his rx-7 and he figures with greddy emanage ultimate,upgraded fuel,race header,exhaust and modded intake,ignition that he will get his goal. as for 280-300 you need to do a very big port and a REDBUILD with new rotors and such. i dont know much about rotories but i know fuel is an essienial upgrade before you do anything to them.you can very well build a n/a 280whp rotory for about 3g's i would figure and based mapped.i say why not?

N/A is BEST!

you can turbo your n/a if you put t2 rotors and housings in it.. turboing a stock n/a will raise the compression to high and your motor will blow sky high.

i guess i will just go with a rebuild and street port for now. can always go turbo later! well thanks guys, much appreciated! anyone know of some good engine management that will work with the NA 13B? I've been looking at like ECU piggyback systems and stuff, but i have never used that before. somethin not too costly, under 1G preferably, unless its gonna create crazy HP, but i really doubt that. anyone kno if apex makes a FC commander for a na 13B? i heard those are really good for tuning. if you guys have NA 13B setup, feel free and post it and tell me how you like it.

1G~!? you can buy nearly ANY standalone EMS out on the market for that much. most rotary guys i know dont use the apexi power fc. They usually either go with haltech or microtech standalones. but if you want something more affordable, piggyback is the way to go. the apexi safc is a great piggyback and tuning friendly. For big results for power band, i recommend you invest in bigger fuel injectors, fuel pump(walbro), piggyback/standalone and straight pipe/down pipe/exhaust. thats where the power of a rotary truly shines... lesser air restriction

[TokyoDrifterxo7]

i've seen some expensive management systems. what size injectors should i get? so far i have the walbro 255 pump, some ignition wires (magnacore?) and a HKS intake. i think i will go with the apex safc, maybe a racing beat header, and cork sport exhaust. i wanna get nology ignition wires because they are grounded instead of my magnacore. eventually an aluminum fly wheel and organic clutch once i get my new tranny. that will probably put me at about 180-190hp

[Motdyn-Ls1fd]

Just put a ls1, lt1 or even a 5.0 motor. About the same cost. More power, more torque, more reliable.

[TokyoDrifterxo7]

will the 84-85 13b na injectors work on a 86 13b na? i would rather have 680cc then the 460cc i have. why did they go lower?

thats the way, appreciate what you have~! learn your basics. you may not know this but IMO(in my opinion) i drive in the mountains, and NA rx7s are great cars. they ARE FASTER than turbo 2s on the mountain. i know several guys who are faster than me and hull *Censored**Censored**Censored* with thier NAs and they are only at 185 to 200hp at the crank. when it comes to NA, the linear power band is a lot greater, traction is better and superb throttle response is all an advantageous factor. as for your injector sizes, i would use 680cc injectors for the primaries and 720cc for the secondaries. the stock NAs have 460cc if i am correct.

[TougeFC]

Here is what you should do. Sell your NA and find a Turbo II. Its easier to start with a Turbo II even if you find one with a blown engine.

You could always put an SR20DET in it if you dont want a V8....

[TokyoDrifterxo7]

ya the 86 NA came with the 460cc. the trick thing tho, the 84-85 came with 680cc. it's hard finding injectors for the older rx7's tho. anyone kno of a site that sells aftermarket injectors or maybe even new stock injectors? i was gonna buy some used ones off of ebay but i dont want them to crap out on me. i'd be better off gettin some new ones and have no problems.

the reason for this dude, is the 84 and 85 1st gen only use 2 injectors whereas the 2nd gen housed 4 injectors. and yes you can switch to 680cc. that would be a nice affordable upgrade for your NA they flow about the same as the greddy 720s so itd be a smart buy. they go for about 100 a pair. id say just use stock t2 550s for your primaries and stock 680s for your secondaries.

[TokyoDrifterxo7]

im gonna go 550cc primary, 720cc secondary, then get a fuel pressure regulator. looking at about 230hp @ the fly. i might switch out the walbro for a RP competition fuel pump. my 7 been running kinda rich ever since i installed the walbro. i need to get a SAFC soon

[Drift_This]

hey man. if your still looking to do the tii swap. my homie migule owns a shop in socal. hes already done one na to tii swap and worked on numerous rx-7 including ryan hamptoms d1/fd fc. his website is www.rmjmotorsports.com check him out.

[s13daver]

for a piggyback safc is great! but if you want something more later get the greddy emanage, iv heard nothing but great things about its tuning capabilities. with the emanage you can also change it to map sensored which is better for tuning and will help you find more power also. im glad you are going n/a!

[aristo]

why not track down a front clip and swap everything over? YOu'd just be a driveshaft and rear end short of a T2.

[teamINERTIA]

Luke you and your buddies aren't that bright, guys that like RX-7's should not put a domestic into an rx-7. Even your ls1 7 is pretty *Censored**Censored**Censored*! i mean seriously the 7's come so balanced that your an idiot for dropping a v8 into it. yeah their cheaper and make more power for less. but would anyone on this board buy a REAL silvia and then pull the sr20 and drop in a v8? doubtful!.

And tokyo dont trip off of not having the power figures you want even in n/a form a properly set up RX-7 is all you need to get the job done. I've owned 3 fc's over the last 6 years and I get sideways and stay there just fine. in drifting hp and torque only count for about 20% of what you need , skill and chassis/suspension tuning make up the other 80%.

and besides that i've driven v8 fc's and fd's and the push alot without the PROPER tuning and that isn't gonna be cheap to add to a swap list, Also it takes the joy out of driving the car. I mean seriously if you wanted v-8 power why buy a 7 in the first place?

Just my 2 cents on the subject so all you flamers keep your mouths shut unless you can make a valid and relavent comment.
