just wanted to say hello, im obviously new to the forum and thought i would share my project with everyone and possibly get some insight as to some tips or whatever you guys may have....





ill post up some nice pictures for everyone once i get back to the house





start-> 1988 mazda rx7 se n/a, blue straight body, mint interior for $500, blown engine



purchased a 13b-re engine, great compression, wiring harness, ecu, turbo, everything for $1550

purchased a twin turbo transmission with oem pressure plate/clutch for $500



koyo radiator free

12x12 intercooler free



electric fan $100

walbro fuel pump $89

engine mounts from banzai racing $210

engine and transmission cusions $100



this is what i have so far, im in the process of ripping everything out of the car, treat the rust where the battery was, ill have to get the materials to relocate the battery for more space to mount the intercooler



sold off the interior of the car for $500 so i got the shell for free which was nice. anyone here know of anything else ill need to get the car running? if the transmission will mount up no issues, flywheel fitment issues etc....just any information would be helpful, as soon as the mounts are in ill get the engine/transmission put in provided the tranny fits without any issue.



great forum! cant wait to see what everyone thinks about this swap! for now the goal is to get the car running...my budget isnt very high, looking to get it running then maybe later ill increase the budget for more power ;P 235ish stock is plenty for now!

transmission for the swap should be a tII not 3rd gen, you'll also need a tII clutch assenbly and your gonna need a tII ECU unless your going stand alone. and the wiring harness from the re motor is usless and wiring will be required. This is goin to be alot of work. looks like you haven't done very much research. good luck

any reason why the twin turbo tranny wont work? i dont see why it wouldnt.....



and im not going to use any guages etc...just aslong as the engine runs thats all that matters....so the harness isnt useless, since i have the ecu from the re engine the seq. turbo setup should work just fine



i dont see how its alot of work really....same work as a TII into a n/a for the most part....im not using any guages or lights whatever..everything will be hard wired to a switch panel





any other inside on the tranny stuff?

jwteknix

the 3rd gen tranny is mounted w/ a PPF not a cross brace like found on your 2nd gen. As for wiring have fun. I dont think you can use any wiring orr the ECU from a re motor. And not using any gauges I find that some what ignorant how will you monitor the vital engine subsystems. Also the easiest way would be to dith all emissions and seq. Systems btter yet get ride of those shity twins and go single also there are minor wiring differnces between n/a - tII. Good luck

darinn

;P i think you read into my post just a little too deeply there....i dont exactly plan to use the oem guages/lights/etc everything will be aftermarket. i do plan to ditch all the emissions and seq system stuff and go single t67...it all takes money and suspension is very expensive to fit into the budget along with the engine...goal now is to get it running with the 13b-re



i dont dissagree that there are wiring differences in the n/a harness and the cosmo harness....thats the beauty of not having to use any of the things on that harness...aslong as the engine runs thats first priority, all other wires can be traced out and used or taken out etc....



thank you on the info about the transmission, i put a deposit on the transmission waiting on the motormounts to come in, not that big of a deal, the guy here will let me transfer that to a tII tranny, only problem is its going to be 2-3 weeks until he gets a TII transmission in from japan.

jwteknix

well you also need a tII driveshaft and rear. unless you get a custom shaft made or buy a mazdatrix one that allows the n/a rear to mate w/ the turbo trans, if going large single your best bet is to swap in all tII stuff i just did all of it on one of my cars wasnt too hard. as for the harness i dont think you can use the re harness for anything the easiest way is to use/ moddify the n/a harness

darinn

i just purchased a tII transmission locally for $225, the jdm import here where i live will refund the money thankfully since we had talked about the fd one not fitting inside the fc.



i am on the lookout for a tII driveshaft already and a rear diff. i dont think the n/a rear is strong enough to support the power im looking to get in the long run which isnt real bad...just 300hp, def a large single is the way to go when the finances are right, i spent alot of money on misc things ie fuel cell, seats, steering wheel, fuel lines and fittings...it becomes very expensive very fast unfortunately.



one of my main concerns with the na harness i have now is that it is older, wires are brittle in certain places, etc...in your opinion what makes the re harness not useable now that you somewhat understand my goal with the swap..just getting the engine running now and everything else later, perhaps wire length? oem guages arent being used so i dont need to combine the 2...not ruling the idea out..just like clarification as to why you dont think it will work.



also will be doing some research on clutch kits. i see they go for $250-400ish on ebay depending on brand...just have to findout what brands are super crap and which ones are decent for the money, any suggestions? i know the clutch/pressure plate/flywheel arent areas to really skimp out on but there is a budget so cheaper the better to a degree...thanks for your input man ive read alot of posts by you on here already...either way this will be a fun swap

darinn

just an update:



got the t2 transmission and t2 rear diff with halfshafts, t2 drive shaft is on its way



i have my eye out for a t2 wiring harness just in case i cant get the jspec 13b-re harness to work.....noone has yet to give me any reasons why it wouldnt work....

jwteknix

its a completely different harness from a different car. a cosmo was never even produced over here, which i believe only came in automatic, theyre also rhd. you will need a US tII harness and go through all the bullshit wiring I just spent weeks on or you can mod the n/a harness you already have. you will need to runn a tII ecu or a PFC w/ banzai adaptor unless you go full stand alone. no if ands or buts about it. srry bout being a dick

haha no biggy man....im just anxious to get it working correctly with the least hassles....i have a 350z engine and tranny setup i was going to use but to fabricate everything and make that work..it was way more of a hassle than the 13b-re which can easily be made to make the same hp......thats the only reason why i went with the 13b-re....



let me read your thread
