Some say it cannot be done but if you test it before install you can just drop some Jspecs in. From what I can judge from other posts that read, it seems most are good to go when they arrive.

Other misconceptions:

1) You cannot install a TII trans without the rear end.
2) You cannot reuse your original NA harness/ECU
3) You need a TII air flow meter
4) You need a TII pressure sensor
5) It cost $200-$250 for shipping (B.S.)

My car is running great with a smooth idle (~750rpm AC on or off), and I get the stock 6-7 psi of boost (for now). As for the rear end, I used the front yoke of an auto driveshaft with the NA shaft and rear yoke to make my "hybrid" shaft. It cost me $155.00 to have the components switched and 2 new ujoints installed with the caps tack welded since the clips won't them hold properly. The harness had to be rerouted in a few places and some wires had to be lengthened. overall it was not too bad after I got some vacuum bugs resolved.
Now for the shipping part, I honestly knew there was a chance I may get ripped off on the motor so I asked them to ship it freight collect where you pay the shipper when he drops it off. That way he could'nt possibly "F" me on that too. That was the smartest thing to do because even with a home delivery charge it was still only $95.96 to my garage floor! after he quoted me about $200 for shipping. And that was for BOTH an engine and trans. shpping from CA honestly would have been more though but it shows that rates can be not so bad.

$800.00 after negotiation for Jspec motor and trans.
$95.96 for HOME DELIVERY shipping

$895.96 TOTAL!

.....7 psi to pass that jerk who cut you off, priceless.

If you are sitting on the fence take the plunge, if the motor has problems you will have a core to rebuild at the least.



My Home Depot Racing intake setup (temporary)

 

you could use the n/a rear end if you made your own driveshaft

 

I did...... from the front yoke of a auto driveshaft and the rear section of my stock NA one.

 

Not bad, makes me wanna swap one soon...if my NA doesnt hold up that is...

 

i got a s5 turbo 2 so it cost a little more ($850)i had a n/a and i was able to use the wiring harness,air flow meter,and for now till i get a turbo 2 rear end i drilled 4 new holes in the turbo 2 driveshaft so it could fit on the n/a rear end,dont need the pressure sensor cause i bought a acv blockoffplate.doing the swap was a lot of fun highly recomended to anybody thinking about doing it.

 

I thought of that but did'nt have the driveshaft from a TII

 

its good to hear positive Jspec stories from time to time

 

Just FYI. IF I were you, and I'm not, I'd buy a turboii ECU and pressure sensor to go along with the fine work you've already done. The Non-Turbo ECU and pressure sensor cannot retard the timing when at full boost. That really, really should be happening when your boosting.

But on the positive side, I've done the same thing with one of my cars and am pleased as punch with it. Especially the *priceless* remark you made above in your first post.

 

How can you see the effects of the different pressure sensors, I just can't see how mine cannot see the boost like the TII one will, plus the aspec vert. ECU is supposed to be the same as the one in the turbo JDM verts.

 

how much power can the NA rear end handle?

 

and what company did you get that deal from?

 

I searched......see we use it sometimes...... I searched for jspec and turbo posts to get familiar with where to buy from and what to expect and found some post from one guy telling another to call a number for a Jspec. It was Japan Star in Monasses VA they had a 1-800 number (I forgot what it is), and one guy there seemed to speak decent english, they had this Jspec with trans for $900 I talked it down to $800 and got them to send it freight collect. I got lucky, I would'nt expect it everytime but this time I got pretty lucky since everything including the trans and clutch work fine. One motor mount was bent and the fan was kinda trashed so the car was probably wrecked and that made me even more confident it would run. Chances are if a car was wrecked it had to propel itself fast enough to hit something else pretty hard. Cars with blown motors only wreck if they roll down a hill by accident. :-)

 

how can calio64 say he doesn't need a pressure sensor just because he blocked off the ACV. i'm afraid he's got the facts mixed up. somebody help the man.

 

the only vert ecu that can handle boost is the n352

 

I have the n338 or 388 I can't remember, but I have been told it is turbo compatible. Plus my car boost fine right now so I guess it is working. But I am sure I am missing some safety systems.

 

well good luck, hope it doesn't decide to blow up on you

 

I plan to take it easy at first and make things safe and dependable

 

Holy crap!!!!!, Was it really for Japan star?!?!?!?! Mine is coming from there as we speak!! Makes me feel a lil bit more confident in the engine. I also got a tranny included with all the acc. on the cheap. Only difference is that I have an S5 A-spec TII wiring harness , boost sensor and AFM That I will be using.

Awesome man

 

I 'm kinda a bitch about my swap so I have an actual TII tranny and rear in my car now, but I have heard (on this very forum) not to take a stock NA much passed 200hp at the wheels(maybe higher for an S5 rear). honestly look around, the other TII driveline parts, besides the engine, are not that hard to find and aren't very expensive. got my Full TII driveline(from flywheel to rear axles) from Kevin at Rotary Resurrection pretty sheap. Might wanna give him a ring.

good luck and have fun

 

BTW, Jon Equest, what paint color/brand is that? looks KILLER

 

Nice counter to my anti-jspec thread...

However, you are just one success story out of hundreds of failures. As i said in the other thread, I did not mean to imply that all jspecs are junk, but that your chances of getting a useable one that will last more than a year are about 50% or less.

This coming from someone (me) who deals with the internals on a daily basis, and sees what most of you guys do not. You only have experience with one core, that happened to be good...I have seen hundreds, some great, some okay, many or most junk.

As always, your results may vary, do what you want to do, it's your car, blah blah. You have stated that you did things a certain way, and that thus far (not very long) things are working well for you at a very cheap cost. This is well and great for you, congrats.

For the general population, this is not always the case, so for you to go around telling all the newbie's that what you have done is the outline for a t2 swap is setting a bunch of people up for failure. Those of us who say "you shouldn't do it that way, you need this part and that part", say that for a reason. Not to mean that it can not be done, but to mean that it probably shouldnt be done for a long time period or on a regular basis.

 

hey there Kevin, that TII tranny and stuff is working great, thanks a ton. I agree that is is definately a crap-shoot, but when you get one super cheap its still pretty cool to be able to get all, or most of the neccesary TII engine components all in one shot, even if you do have to rebuild it within a year.

thanks again and much respect to ya for you and your work.

 

dont know about your turbo 2 but my pressure sensor is on the passenger side shock tower and has a vacuum line that goes from the sensor so the ACV. since i have no acv no more i dont need the vacuum line that goes from it to the sensor..there for there is no use for this sensor...so you get your facts straight..***

 

and i also got my engine from japan star...and the motor runs like a champ

good luck

 

I totally agree that many Jspecs can be junk, I was actually prepared to find myself with a 0 compression core to rebuild but at the price I figured it was worth the risk. As I said I got lucky and I would not expect to get that lucky twice in a row. I just have personally seen that so many people are afraid to fix up a car and instead, sell it or junk it and move onto the next. My suggestion was do something..... and if the motor turns out to be bad, get it rebuilt, at least then you will have a turbo motor to start with. The Aspec TII donor cars are few and far between, that combined with the fact that over 98% of all cars of this age in America have well over 100,000 miles means that even a 10% chance of the famous "30-50 mile" Jspec is pretty good odds. I also agree that unless you are willing to take more risk or if you want it done right you do need to get a rebuilt motor from someone reputable like yourself. I have a local freind (Marshall) who got his motor redone by you and I seen it, and was impressed. It looks like Mazda just made it, if mine was bad and they would'nt have honored the startup warranty, I would have sent it up to you for a rebuild. I definitly do not encourage anyone who is a new to auto repair or rotarys to drop in any old motor, I was just offering my own experience to go with the ones from people who got bad motors.
