J30tt progress

[95-J30tt]

thank you all for your feedback, happy new year to everyone;

i thought that i would find some machine shops open today but i didnt, so i'll see what i can do in regards to the oil filter bracket by tomorrow, i'll try to get mine redone to fit.....

thanks a million to drape123 for all of his help since i started this project, i'd really appreciate it if you can supply a part number, and the brand of the bracket shown above. i'm going to try to fabricate joints for the bracket that i have now via machine shop, if that cant be done, then i'll have to get the bracket in the last picture above, "and most likely that it is going to be the case", sorry for if i dont make sense, i'm still hung over from yesterday and on no sleep

i'll update again once i'm fully awake, thanks again everybody

[J30Guy612]

Nice job! Glad to see your making a bunch of progress!

Besdies the oil relocator kit, what other major problems have you run into?

Drape, nice to see someone on these forums that has already completed the conversion! Congrats!

I noticed your signature says 396HP, is that crank HP or wheel? Also, what mods do you have on your J30, besides that TT motor running at 14PSI, and the ECU Re-Flash?

If your running just an ECU Re-Flash, 14PSI, and making that much power thats awesome!

You guys are both badass!

[drape123]

Sorry about dying on ya'll, i've just been consumed with other projects. i am spending most of my time these days on my 240sx, KA-T. Just finished the fully built motor going to test drive her today

[drape123]

I had one cnc machined from a local machine shop, but i checked ebay a few months ago and the same type of one i paid $100 for was selling for half that!

[drape123]

396 to the crank, so about 350 to the wheels

the ecu reflash was made by me in house, just little old me and a wideband

95-j30t will be running the same code! its the funniest thing, smoking a Camero SS with a J30 Sedan. the look on the drivers face is priceless.

[J30Guy612]

Ya smoking a SS in the J30 would be pretty badass =)

Including the motor, and all the little odds and ends Drape, what would you estimate the total cost of the swap? Just a ballpark would be great!

Are you using the ZX TT auto transmission or the J30?

How are things holding up, and how long ago did you perform the swap? Is the car just as reliable as a stock J30?

Thanks a ton, sorry about all the questions, just questions I've had!

Keep up the great work guys!

Nice job 95-j30t!!!

Can't wait to see the finished product!!!

[DominickJ30]

Id say 5k total for the swap is optomistic.

[95-J30tt]

finally chiped the ecu, this picture shows the stock ecu chip (the one that has a sticker on it), this is the 300zx ecu by the way, the J's ECU is a 16 bit and it is reletavely hard to chip compared to the 300zx which is an 8 bit, and the J's ECU CAN NOT be used for the swap, you have to get the 300zx tt ecu, i believe that the auto ecu will also work with the manual but dont quote me on that



this pic shows the socket that was soldered in place of the stock chip, why a socket?, well you can swap chips when it is time for state inspection or the equivalent emmision testing in canada, as the upgraded chip (when installed) will cause the car to fail emmision testing.....

[95-J30tt]

finally got a hold of the oil filter bracket, i didnt know that you can just get one section of the kit, so i saved some money, but i guess that i have to re thread it, if i'm lucky then i wont have to, but still unsure, as i have not tried to install it yet, well there is the pic with the part number and so on







now i dont know what size of allenkey i need to bolt the plugs pictured above, i'll have to sort that out before i approach the installation.

to install this part into the engine's oil system, the TT engine's oil bracket (the stock one, the one that comes with the engine, which is not the same as the J's, the J's engine has the oil filter thread coming straight out of the block, however, the TT engine has a filter bracket bolted to the block due to the turbo exhaust system) has to be taken out, and then screw in the oil filter bracket kit (the one in the picture) to it, and then install the stock bracket back into the block, i has to be done that way because there is no clearance for the kit's bracket (the one in the picture) to be screwed into place with the stock bracket installedthe stock filter is a pain to take out and install, there is almost no clearance to reach the four screws holding it to the block, if you look above in the prevous posts, you will notice that one of the pictures shows the old aftermarket oil bracket that i have installed (the one that didnt give clearance for the hoses to be installed), it is screwed in to the stock oil bracket, it is very complicated to discribe because they both have the same name (oil filter bracket)....., i'll be taking pictures and hopefully that will give everyone a better idea of what i'm talking about

[95-J30tt]

been working on the car most of the weekend, i finally got the boost controller installed, installed the ecu bracket to the vg30dett ecu, and some minor work here and there, and most importantly, got the engine's bracket out, that was a hard task, if anyone is planning to do the swap, save yourslef the trouble, put the filter kit with the engine out, it is so much esier, well it is still doable but it takes a lot of time and effort with the engine is the car....

the bracket that i bought (pictures above) does work, but i havent gotten that far yet, i took the engine's bracket out, checked the threads and all, and it is all perfect, the aftermarket bracket needs a little work before i can install it, i guess i'll leave that till next weekend

i guess that would be pretty much it before i can safely start the engine for the first time, i hope that i can do that by next weekend, i'll keep you all posted...

[95-J30tt]

by the way, as for price of everything, it ran me about 3500 canadian, i'm still technically not done yet (about 400 or 500 more, i hope, or else i'll get a heart attack....loool)..... dont forget that i had to do this without a step by step instructions, and no picture support, so i'm sure that the time can be cut down by a big factor, and money wise, it would cost less, mot much less, but definately less....

[drape123]

I now have daughterboards that can be installed in the J30 ECU that allow you to chip the 16 bit ecu. (just finished the design a few weeks ago)

so now we can easily chip

J30300zx240sx180sxetc

pretty much any nissan 89-96 with 16bit ecu.

im excited about that.

Sinan, im glad to hear you're almost done. you will be impressed. almost instantanious boost

[pugstrip]

hi im new on this site..i own a 94 j30 190k miles ..it starting to paw radiator fluid so i bought a wrecked 95 with 88k miles that runs good...in swapping eng/trans do i need to change ecm's?

[J30Guy612]

Pug you may want to start a new thread about that topic Welcome!

95, awesome job on making quick progress, can't wait to see the finished result!

Keep it going man!

[95-J30tt]

i would swap the ECU too, i dont know about the 94, but i know that the 95 ECU is a 16 bit , and i know for sure that they are both OBD1, so if you have the 95 ecu and you are installing a 95 engine, it wont hurt to swap ECUs too, it is a 20 minute job at the most, hope this helps, good luck

[95-J30tt]

i have noticed from looking at the pictures of both engines that the J's engine has the dipstick coming out from the front passanger side part of the engine, where the TT has it coming from the rear of the driver side part of the engine, i'll look more into that, to see if i can move the dipstick to the J's location

here is a pic of where the J has the dipstick



and here is one for the TT dipstick location

[elwesso]

just for reference, you swapped the TT oil pan to a J oil pan, right?

[95-J30tt]

yup.....

[ttinfinitiM30]

well i looked at the underside of my tt block and noticed that the location of the j30 dipstick is drilled out already it jus has a plug in it or isnt drilled the whole way. soo this is a much better spot then the one i had already mentioned. altogh u will probly still need to drop the pan to do it.

[95-J30tt]

wow, that sounds great, i'll be looking into that tomorrow and i'll see if i can avoid pulling the engine out to do the relocation

[ttinfinitiM30]

have you found any goood locations to hoist up the engine with the plenium on. the locations ive been using run up along side the plenium. and put some pressure on it. i took mine off for the mock up stages but i figure it will be easier to put the plenium on when it is out side the car then when it is in.

[95-J30tt]

i took out the coils, and ran the chain through the middle pipe of the plenium on the driver side, and the front pipe on the passenger side, i used that method to get the engine and transmission out as one piece, it worked great every time, 4 times in total

[ttinfinitiM30]

Ahh... i had thought about that but i feared that would b too much pressure on the manifolfd. cause the whole engine/trans thing weighs bout 7-800 lbs. but i guess if it didnt give u any probs then my final aproach ill do that. thanx

[95-J30tt]

does anyone have an extra golden (t) that mounts on the trunk lid, where can i get them from, been looking around for a couple of days last week and got no where....

[elwesso]

try emailing pop-pop... you could just get a new emblem from the dealer (theyre only like $20 last time I checked) and then sell the remaining J30...

[95-J30tt]

i finally got the car started, sounded smooth, idles good when cold (at about 750 RPM), i never tried idle when hot yet.... however, there is a leak from the oil filter relocation kit's hoses, i guess that they are not tight enough or need some more sealent, i'll be working on that during the week (2 hours to fix)... there is a little transmission fluid that was leaking also, but i found out that one of the clamps for the transmission cooler lines was not tightened, so that was an easy fix (5 mins to replace the clamp and tighten)....after running the engine for over 10 minutes, the heat gauge was just below half (the way it should be), no check engine light yet..... (i hope not for a while)..... also checked the AC, it worked fine, checked the climate control, works just like before, RPM works good, gas gauge works, but havent tried the speedo gauge yet, all lights work inside an out, brake works just like before, so electrical seems fine

the leak in the picture below took about 15 minutes to accumilate with running the engine at an average of 2000 RPM, there is some transmission fluid in there also, i'm astimating it to be about half a litre of oil, and less than a quarter litre of transmission fluid, so i topped everything back to level (i dont have a working engine dipstick yet, so i astemated that one)



i fixed one side of the filter kit's hoses (the one in the picture), i removed the hoses, added sealent, and installed the hoses back, and tightened the hoses pretty good (i think i fused the metals together.....loool)



now i have to do the same to the other side of these hoses, and i hope that this would be it for leaks

i havent driven the car yet, but hopefully during this week, i'll also take it to a mechanic shop to get the ball joints replaced (found the ball joints after almost a year of shopping) and to re-thread some bolts that broke during the swap (6 bolts in total), i'll keep you all updated

[ttinfinitiM30]

thats awsome man. good to hear ur in the final debugging. oil leaks suck but at least u know where they are. hope u get to go crusin in it soon man.

[Midwest_Drift_Shop]

Wow, great work. This makes SR20 swaps looks like childs play. By the looks of it, no easy swap.

Once I get up the money, I want to attempt this swap, and try a 5-speed swap too.

Good Luck on the swap.

[95-J30tt]

ok i couldnt resist, i drove it around in the underground garage parking, the speedometer works, selector beam is installed correctly, steering is good (a little heavy), transmission responds well when the engine is cold, when the engine warms up, the car feels heavy at starting from a stop, and then smoothes out.....

boost controller wiring is all check (made a mistake by hooking up the positive wire of the controller to a ground, but sorted that easily)

checked lighting, all good, i didnt think that my engine remote starter would work, but it worked, engine codes are 35 and 42

42 is a fuel temp sensor, it is located in the fuel rail of the tt engine, all J's of all years dont come with such a sensor, so to solve that issue, i have the J-spec harness that came with the package, i'll take the sensors plug out of the jdm harness, extend it, and install it in the J (from the sensor to the ecu)

code 35 is the EGR temp sensor, i dont have an EGR temp sensor in the engine because it is a JDM engine (they dont come with such a sensor), i have the wire for it though in the J's harness, i have researched, and that sensor doesnt effect performance, emmisions of the engine

by the way, the tt is supposed to idle at about 900-1100 RPM, so i'm going to adjust that next

there is a strange connection between the coolant temperature sensor and the way the car idles, if that sensor's contact is corroded or if the sensor is unfunctional, then the engine would not idle correctly, and would run rich, so i'm going to clean that tomorrow....

well i'm getting closer to completion, i'm hoping to get the car fully functional by the weekend, i'll keep you posted
