Ok.. today me and my boy were performing the conversion. and i dropped the trans, drive shaft everything. loosened the engine mounts... but when we looked at the wiring to the NA. and my JSPEC engine its a lil different. the Jspec has 4 clips for vacuum hoses. the NA has 5. 3 colors match, 2 dont. i know that japan has lower emissions than US. does anyone know how to overcome this prob?

The na harness is different from a tII.

Slightly different but not to much. It doens't have the wires for knock control and soem othe rstuff. YOu better get yourself a TII harness and the sensors for it or go haltech



THe color clips for the vacumm hose is the least of the problem to worry about, that's no big deal.

Yea, get a T2 harness or haltech, using the NA harness will only lead to problems, lol...



...not to sound like an ass, but have you properly researched this conversion?



I'll be more then happy to help as I have done this twice now,lol(as far as pulling an Na motor and putting a T2 motor in...twice)...

what kinda $$ are we looking at here. Not everyone is rich but we all want the break neck acceleration of a turbo =P

do u have that write up available for email. i am like a baby learning to walk.

IS yours running yet?Yours should be running before 1revvin7's right?

You have got to be kidding me, guess I will just link this thread.....

Lol, mine WAS running with the Jspec as far as having all the wiring harness going, I even drove the car on one rotor for about a week,lol. However, I have not yet started my new motor. In theory I should have mine running again before revvin https://www.nopistons.com/forums/pub...DIR#>/wink.png



I just need oil lines, which have been on backorder now for a lil while, I'm gonna contact the company shortly to check on there status. If they get here soon, the car will be up and running by mid to late march...and ready for track use by april.

BTW, the writeup i did was completely wiped off our server due to lack of space,lol...but I'd be more then happy to answer any questions you have...you can email me at rx7tech@1320engineering.com

haha i wonder who is causing the backorder? https://www.nopistons.com/forums/pub...#>/biggrin.png I ordered 50 from them. https://www.nopistons.com/forums/pub...IR#>/wacko.png Well if I didn't owe people cash, **** would have been running years ago.

Yea...I'm still payin for my original conversion to the Jspec, lol.



Corksport said they'd get more of the lines in this week, so hopefully my order will arrive soon...then, only then my friends, will the darkness fall upon all those who ride with "H" on the hood, only then will the hearts of every VTEC driver stop beating and then, ONLY then...will my car run,lol...sorry..went off on a lil sadistic rant mwaaaahahahahaaaa....







...seriously though, i just want the damn thing to run again, my protege is aight, but these damn RSX typeSs runnin around my town are pick'n on me!

i cant wait to get my jspec running. when my cars seals were going and it was overheating i was still rippin these freakin rsx's. not the type s.



they crack on me now. y0 that car will remain on jack stands and that jspec right next to it.



wait till the engine of this week ! ! ! thum thum thummmmmmmmmmm......

how does a haltech or any other stand-alone work? What sensors do they use?

what do you mean how does it work? You input ignition and fuel maps that play by each 1-2-3 bar map senor, whichever you have. It uses an air intake temp, water temp sensor, Tps and stock(or aftmarket) CAS, but they are many extra you can get and there is a long list of **** it can control, ie: e-fans,nitro,turbo fans,TT,X-tra fuel pumps, etc etc. But whats nice is it uses a map senor instead of a afm and map(pressure) senor in conjuction, and you easily tune for best hp safely, and ofcourse control huge injectors.

That makes me want to buy one. You should be a salesman.

haha https://www.nopistons.com/forums/pub...#>/biggrin.png yes everyone should get one! no more blowing engines yay!!! **** I could of had a big ass turbo instead of the haltech, but I wanted to keep the motor for more than a month https://www.nopistons.com/forums/pub...DIR#>/wink.png

The stocker ECU can't handle a big turbo can it?

well it can't really control bigger injectors which are needed with a bigger turbo, even with a s-afc, its hard to get the transition just right, all it takes is one time, BOOM!

Kinda figured it would lead to a case of the vosko cyndrome. https://www.nopistons.com/forums/pub...IR#>/smile.png Thanks for the info.

I'm glad to hear you are changing the tranny and the differential! I thought I could get away with doing so, and broke both in fairly short order. Here is what I did to the diff - it came out of the car in 2 separate pieces!



Jason

post another pic of your custom na/t2 manifold thats dope!!

I see theres a new vosko?Nice diff you have thier. https://www.nopistons.com/forums/pub...#>/biggrin.png https://www.nopistons.com/forums/pub...1047683894.gif

Here is a bigger pic of it. You can see some of the places I had to build up with weld to end up with a nice flow. If I remember right I used about 1lb of aluminum TIG rod on it.... The engine made great power - too much power for everything else behind it!



Jason

now if you are set on turboing an n/a motor thats how you do it!!

hey, i encountered another problem. when i went to put the engine in, i passed the new engine harness through the fire wall to connect it to the ecu and the plugs are different. now i have a N370 ecu which those plugs dont work. and i have a N326 ECU, and those plugs dont work >:/ .. thats got me in high thought. also, there is two that connect from the engine harness to the ecu, and theres one that is suppose to connect from the driver side harness to the ecu. the one from the driver side connects perfectly but the ones from the jspec engine dont.



if u have a suggest or a solution please contact me.

put a motec m880 in it lol they are only about 10 grand and can control emissions and all that good stuff https://www.nopistons.com/forums/pub...IR#>/bigok.gif



lol j/k i cant help you on that..just post whoring

Isn't the N326 ECU for the NA?I know the N370 is a S5 T2 ECU.As for your wiring....I hope rotaryman88 can help.Hes got a J-spec in his.He might know the wiring part of it.

How much power DID the engine make?

Unfortunately I never got around to dynoing it. It kept breaking things; tranny, diff, clutch, and finally blew the water seals. Had evidence of the rotor housings moving in relation to the side housings which eroded the sealing surfaces and the seals.



Don't get me wrong - it was a stock, unported 6 port using a stock S5 turbo. It wasn't making huge horsepower, but it did work quite well considering how cheap the parts were.



Jason

i want to see dyno of a turbo'd 6 port that has working aux ports



i should turbo my street ported s5 6 port/turbo hybrid motor just to see that.
