T2 Swap

[Justin51982]

I figured the other thread had run its course. Since I have decided to start to RX7 now and decided on a T2 conversion, I am gathering up parts and stuff to get the car completed. I was able to pick up a set of Speedline Corsa wheels for the car. I went up to the car today (It's in Gainesville right now, I am bringing it Kennesaw the weekend of the 13th), and put the new wheels and tires on it. That alone made a big difference.

Pics are below:

did the wheels magically clean the car as well?

Looking good, looking real good.....:goodjob:

No that was the rain and a pressure washer. :)

Thank You!

i know. atleast it has matching rims now. hows the interior looking?

[yomomspimp06]

If you're interested I've got a S4 T2 swap going up for sale as soon as I pull it out of my vert. To run in an S5 I think you're going to need the S5front cover and oil pump unless you decide to run premix(chime in here Kain for clarification)

[yomomspimp06]

your car looks great BTW

[Justin51982]

Yeah the wheels that were on it, well two were old skool toyota sawblades, the other two were spare tire wheels. Interior is a little rough, Dash and console is excellent, the rear carpet is excellent, door panels are excellent, but are grey (I want black) seats are rough and cockpit carpet is rough.

Should come alone. I was thinking doing to doors and seats in black leather with red stictching.

totally doable, but not needed. just premix, or leave the s5 omp hanging by the harness and geet the s4 unit in there and working.

but the s5 requires the omp. limp mode will be induced sans omp.

[Justin51982]

I'm weighing my options on this engine and the S5 I have my sights on. I have a few things to look at with both. So I will have to see.

[kain]

the s5 is also beefier. especially in the rear iron. the s4? not so much. but still 400 whp capable.

What is the S5 capable of?

never thought of that because the s4 is mechanical versus the electric S5 right? This one is in working order so I suppose just leaving the S5 hanging at the harness wouldn't be a bad option.
Both engines are capable of pretty much the same power. The advantages of going with the S5 is mainly in the stock turbo.(wastegate is larger for boost creep and the they ditched the stupid twinscroll) The turbo on the motor I'm selling has the wastegate ported and the flapper for the twin scroll is locked in open position BTW. Do your research but hopefully you pick up my motor. Either way you'll be getting a good one because Japan2La sales great motors.

Part of my problem too is regardless I need a new wiring harness. My car sat for years before I got it from the PO. In that time, critters of some type managed to get and chew through the harness in at least 3 different places (that's is from what I can see from the engine bay, it may be more. So to me I will need a harness regardless of which way I go.

[yomomspimp06]

whatever you do get a N/A harness...much easier to adapt to the car than the T2 harness

[Justin51982]

I could see that to be true I think. Hopefully, regardless of what I end up chosing to do, I will get some help on the car. I am stoked to get this thing back on the road.

the block? the rear iron doesnt crack. people make 800 wheel hp in those, but thats with new studs and other mods to reinforce it. the s4 iron cracks in a certain spot as the engine wants to twist, it cracks. not bad, but still, enough to piss you off and have to remove the iron. still... 450 or 500 wheel hp till it cracks is pretty safe for daily driving.

the harness is chewed? remove the NA harness and see how much of the actual chassis and other harnesses are actually chewed.if the chasis harness is chewed, then that can be rebuilt and not worried about.

the difference between s4 and s5 t2 engines is a lot. the s4 has lower compression rotors, crap turbo and crap waste gate, and the intake is on the small side. not to mention the s4 rear iron. also, the spark plug locations on the s4 vs the s5 rotor housings are slightly different. s5 is basically the better engine hands down. turbo is better (compressor wheel is better with a better waste gate in the turbine housing ), rotors are higher compression, the iron doesn't crack, and the intake manifold has huge ports.

as i have suggested many times over and over, just ditch the stock electronics man. new wiring harness with new clips is SO nice to have. especially when they dont break when the wind blows wrong.

Wow, you are very knowledgeable, and I appreciate the help and the advice. The S5 engine will come with a new harness, so that might be the safe bet. It sounds like the S5 might be the way to go, especially if I have future plans to add more power to the car. I am grabbing the car from my mom's the weekend of the 13th, next month. That being said. As soon as it get's here, I will try to find an engine hoist to use, or buy, pull the engine and see how bad the damage is to the rest of the harnesses. I also have to pull all carpeting out of the car too for either cleaning or replacement, so it might be pretty easy for me to re-route a new harness anyway. As I said before I might ask you to come by to get your input.

[yomomspimp06]

I thought the intake manifold having the larger ports was only for the N/A....learn something new everyday. Everything said is very true except for I've never really heard of problems with the rear iron cracking under high HP conditions...Guess I need to start doing my own research.
When you get ready to do the swap I'll lend a hand too

Thanks man, I appreciate it. Its always fun to meet with some other rotary guys.

[Boosted FC]

Justin, hit us up if you need help. I'm right in Dallas.

For sure! You are really close. As I said, right now I am planning on a Feb 13th pick up, but if I can do it sooner, I will.

this is what happens when you abuse an s4 engine. is the dowel pin right at the oil filter pedestal. the s5 turbo engine has thicker material around this area.

the intake ports are the same, the runners and the runner diameter for the intake manifold is different.

[yomomspimp06]

hmm so I guess the question would be are you "going" to run 400whp? wanting to and actually doing it are 2 different things. At that point you can't run the stock turbo or even a BNR stage 4 and reach that power. well in one case I've read about it done on a stage4 but that was on a streetport. Japan2La hooked is hooking up with a great price right?

its even been done with stock 3rd gen twins. 400 wheel hp isnt realy that hard to accomplish.

[yomomspimp06]

whoa never seen a 3rd gen set-up on a 2nd gen. the more I talk about this stuff the more I want to continue my build

dude... rx7's are great because you are not limited by much. hell... there are people making 200+whp from turbo engines with no turbo and some porting. thats impressive.

one 1st gen member has a 13b re in his car and its making 230 rear wheel hp. no turbo, just some choice mods, porting, and a great tune.

[yomomspimp06]

well I got a guy coming up from FL to pick up my T2 set-up...whatever he doesn't take will be posted up soon. guess I'm leaving the game for now...I've got my eye on a rx8 or '10 mazda3 :)

[Justin51982]

Picked up my T2 hood. It is in awesome shape. Thought I would share....

http://i77.photobucket.com/albums/j61/Justin51982/IMG00067.jpg

[yomomspimp06]

very nice...I like the stock hood with front mount... mmmm sexy. It's not a big deal but it's just barely easier to see with the stock hood

[Justin51982]

I have a question, once you do the turbo swap, can you still run regular? Or do you have to run mid-grade or premium.

[David88vert]

Run premium on any boosted or high performance engine.

[kain]

Run premium on any boosted or high performance engine.

unless you use water injection like me. i run 87 regularly and i get no knocking or pinging.








but like david said... 93 man. or just go e85. heh

[Justin51982]

Thanks again. I'm picking her up from my mom's place this upcoming weekend! Excited to get working on her.

[David88vert]

Very true. The first knock though....

E85 would be fun.:D
Rotarys can run on as low as 70 octane without boost.

[Justin51982]

Brought the 7 home to Acworth over the weekend. Still sitting on my trailer. Waiting for it to get just a little warmer to unload it.

[Justin51982]

Thanks to Roger, I got my S5 tails today!!!

Sexy!

yah i know, in the warm months i use 93 and in the colder months i use 87. no point.

[Justin51982]

Unloaded my 7 last night, sitting in the garage. now to start pulling it apart. If anyone is bored and wants to help some weekends and weeknights when I start this, let me know!

[DVSRX-7]

Thanks to Roger, I got my S5 tails today!!!

I miss them. :cry:

Oh well I'll have some later on in life :rolleyes:

Did that guy email about the center piece for them?

[yomomspimp06]

I'm off this weekend and if Trini wants to buy my exhaust I'll drive over

No he didn't and I do need/want it. I put the S5 tails in tonight and they look good. I also started giving the car a well needed cleaning. There is a lot of work ahead, but it's gonna turn out good I think.

Oh ok. Well I'll e-mail him to see what happened.

Does your car run?

Not to my knowledge, the wiring harnesses are all messed up and the car has 160K on it. Also, someone switched the S5 Manifold with an S4. So instead of attempting to get it right I decided to go with the swap.

Oh yea I forgot.. Does that engine even spin? If it does then we can do stuff :D

[Justin51982]

Oh yea I forgot.. Does that engine even spin? If it does then we can do stuff :DIt spins by hand. What did you have in mind? But it has the wrong manifold and stuff on it, and it needs new harnesses, what is your thought?

[Me86Rob]

lol @ wheels. Same ones i have on my corolla :(

[Justin51982]

Similar style, but mine are different. I have 17" Speedline Coarsa's lightweight wheels.

*cough,cough* CARBurator :crazy:

No need for a harness :goodjob:

u still got your carb ser-up?

[Justin51982]

Nah I dont want to do a carb set up on this

[DVSRX-7]

Nope, sold that car already, wish I didn't :cry:



Nah I dont want to do a carb set up on this

Just throwing the idea out there :D

im going fuel injected for about the same price. im venturing int o the mega squirt relm.

[yomomspimp06]

hey Kain I'm messing around with a program that will help me with tuning so if you can datalog then I can quite possibly help you tune. I'm playing around with it now so by the time you go with the megasquirt I'll be able to help you out.

I have messed with EMS before but never on my cars, but carbs are way harder to deal with than EMS's dude truth be told! It's about the same shit to me. Don't know what your doing with either your going to fuck something up.. quick.

[kain]

yah i know. carbs are like... old world magic.

[DVSRX-7]

yah i know. carbs are like... old world magic.

Shut up! You just scared of touching a carb! :yes:

[Justin51982]

Carbs are a different world, not bad, not good, just different. My MG has SU Carbs as does my '69 Datsun. You have a lot of options to really tune a car with carbs. Then again, with computers, you have a lot of options with FI and adjusting the computer system. Just depends on what you want.

uh... what?

[Justin51982]

Got the S5 tails in and the T2 hood on, and starting to unbolt the engine mounts. Just and update. :)
