aight so i just bought a 1990 GXL FC rx7

its practically in mint condition and the engine only has 55k miles on it

and ive learned that its hard to push anything over 200 hp on a NA engine so



Do i need to buy anything other than:



* TII engine (does it matter what year it is?)

* TII transmission

* TII drive shaft



and instalation fee https://www.nopistons.com/forums/pub..._DIR#>/dry.gif



how much is this gonna run me?

and how much could i get if i sell the NA engine as is?



(dont waste your time flaming me, cause it wont impress anyone https://www.nopistons.com/forums/pub... )



thanks guys!

if your goin to just swap to a t2 only you will need the following

s5 t2 motor

engine harness and matching t2 ecu

all the t2 spacific sensors

t2 tranny

t2 drive shaft

t2 diff and axels

at minimum t2 fuel pump or a turbo 255lph

basicaly all the t2 drive line components and a t2 starter

then there is some odds and ends you may want to go with like springs and suspention upgraded and posibly the radiator as the na rad doesnt cool enuff in hot weather for the hp a turbo can put out.



its not rocket sience here you want a t2 swap you will need everything t2 under the sun to do the job right what can you posibly be confused about



randy

well excuse me randy for not being a rocket scientist

but thank you for your information

Actually, here is a real list of what you need, if you don't have the time or resources to get everything TII all at once.



-TII complete engine

-TII ECU

-TII engine harness

-TII AFM, boost sensor

-TII throttle cable

-Some kind of aftermarket boost gauge

-TII, FD, or some better fuel pump (Walbro 255lph if you plan to go big.

-TII hood



Put your NA flywheel on the TII engine. That way you can use the NA driveline, and starter.



Your FC looks familiar.

if you go with a na drive line your trans , diff and axels wont last long. if your goin to tear into the car to do a swap do it right the first time , do all t2 drive line parts so you wont have to redo the drive line at a later date.

If you are a mad tyte dorifto king, then yes you should change the driveline.

If you are a 1/4 mile king, then yes you should change the drivelline.



If you just drive about enjoying your turbocharged FC, then no, the N/A is fine. Ever heard of Aaron Cake? Enough said.



Oh, and going on 3 years with the NA driveline. 2 trips to Deals Gap, and alot of random tire destruction.



But maybe my car will self destruct tomorrow because I 'cheaped out'

thanks everyone , ill be sure to give the updates when i get the cash



(around march) haha



and yeah i do plan on drifting the crap out of this thing so

...i guess im changing the driveline lol

dude seriously you are one of the lucky ones, we go threw 3 na trannies a year road racing an ITS s4 with a non ported motor, i broke 1-3 gears in my s5 with only a 50shot . i know alot of other guys that have na trannies that smoked with what had seamed like they just looked at them wrong.



randy

i bought a JDM front clip, its the easiest way to go all you need is the diff and shafts. it costed me 2400 including shipping.

I like to keep my fingers crossed.



I am actually getting rid of my 17's and sticky 255's out back in favor of some BBS vert wheels with 225's all around. That should put less stress on the driveline and prolong the inevitable.

i have a TII motor with a T70 with pretty nice power. NA everything behind the motor. holds up nice. and the longer gears make it nice on road. i have seen many NA drive lines hold up to plenty of power.

I agree, not as weak as people make it out to be. But def not a racing setup.

All in how you drive.



Worst case scenario is you get to eventually swap it once something does snap...

Dont forget their are two kinds of NA trans depending on the year.



Swap the T2 stuff in, the NA driveline is weak and if you have a T70 w/ an NA driveline, you must not be making the power you should be or you havent driven the car hard enough. Even FD guys pop difs and trans from time to time at the track... you mean to tell me the NA driveline is stronger than an FD's?

well, mine is a 91 NA tranny.



obviously not stronger than a FD or a TII tranny. no one has ever said that. It's just people make it seem like any power put to a NA tranny will break it. very untrue. TII is the better choice of course. but an NA will hold up for quite while until you have the money for the inflating prices of anything TII. and i like the gearing of a NA tranny also. matched with a 4.3 GTU rear i think is a match made in heaven.

so would it be okay to just buy the engine and the trany and install it

and then when i get the money swap the drivetrain?

swap the TII motor in and keep the NA tranny until you have the TII rear end, axles, and drive shaft.

*you'll need to swap the NA flywheel and clutch to use the NA tranny on the TII motor.



if you want to use the TII tranny now, then you'll have to buy the drive shaft for it from Mazdatrix (waste of money if your going to take it out later)



either way is ok.

i just asked my uncle about this situation



and he recomended a supercharger instead of buying a whole new turbo engine

anyone ever done this or have any knowledge about it???
