The N/A to TT swap is definitely a difficult and time consuming job. If you don't have the right equipment, then it's an extremely difficult job. It's not a weekend warrior job. This is something that takes a lot of time. Please don't give advise like this....someone may actually take you seriously and wind up way over their head.

I can gurantee you wont get the whole swap done for $2500 unless you cut corners and rig stuff which will just cost you money down the road when you blow **** up.

remember the old Wendy's commercials from the 80's?
"Where's the Beef!?!"
that's how i feel about that site.
it's a nice site and nice to see Ash has his own site but there's a lot to be desired still.

90 300zx N/A to JDM TT swap question

I have a 1990 300zx NA. Im thinking about doing a JDM motor swap to make it Twin Turbo. I dont know that much about swapping motors so heres what i have so far.......

---I found a website that was selling a JDM TT swap for $1650....ENGINE ONLY> Just comes with engine and 2 turbos.....

--Question: Will my N/A wiring harness work with the TT motor? And wheres a good place to get a used TT ECU?

~~Thanks..

if you're gonna do all that, wouldn't it be better just to get the ash-spec or JWT ECU instead in order to immediately get rid of the top speed limiter and increase your rev limiter in order to get more use out of those turbos? its better to go ahead and spend the 300 bucks now as opposed to getting a used ECU for 75-150 dollars just to later on upgrade it.... :burnout:

B300z-- How much do used TT wiring harnesses go for? I'm trying to get out of this swap as cheap as possible so if the NA harness will work, I would like to use that one. If only minor modifications like wire lengthening is required, then I could do that.
~also, how is the TT tranny different from the NA tranny? is it gear ratios?

kbebrynt--So a used TT ecu is about 75-125 bucks and the JWT upgraded TT ECU is 300 or so? How much better is the JWT one? and is it worth it?

or U can do the best way get a front clip (nismolmr). for about 2500-3000 it includes everthign. if anithign U just need to tweak teh tranny cause it has bin sitting for so long. send the ECU to JWt or Ashspec. and it's the best way to go. im doing one my self in a year or so.

im not really sure about TT stuff...your better off asking someone with a TT, im sure they will respond to this when they see it.
as far as ecu...get an ashspec one from www.z1motorsports.com theyre 300 + core charge with an addition of around 40 hp i believe is what they estimte, along with eliminating top speed limiter and raising the rev limiter to 7200. they have been proven to outperform JWT by just a little bit. its in rizzspeeds link page. you might look there for TT swap info as well.

So if I bought a VG30dett w/stock turbos, ECU, wiring harness, and all accessories.......Why would it cost so much more to put it into an NA chassis? Granted I would buy new motor mounts and power steering lines.....Why are people saying that it cant be done for under 5 grand? I dont get it......but im new..

If I had a dollar for everytime I heard someone say they were going to do a TT conversion, though how many times have you actually seen it? My point made...

it could be done for under 5K if you bought a front clip and did all the work yourself.
But most ppl are unable/unwilling to do the work themselves.

get a clip.
there's many, many differences between NA and TT.
have you considered where you going to get intercoolers and piping from?
Search a little and you'll see that this topic has been covered many a time and you'll find your answers there.

Are intercoolers required on a TT? Or is it just a nice thing to have? ....and if so...does anyone know where I can get a front clip of a JDM 90-94 TT 300zx for about $2,000-$2,500??

~~What all comes with a front clip? Does it come with the dashboard and gauge cluster? fenders and everything?? I think that might be my best deal cause I need a drivers side fender too.

Thanks..

Intercoolers are only a nice thing to have if you wanna make any power.

A front clip is everything from the firewall forward. Usually they include the forward section of the cabin, which includes the dash, glovebox and steering wheel.

Im a jet engine mechanic so I'm totally willing to do the work myself. I'm going to become a Z owner this saturday. Im getting a 1990 NA needing some TLC. My first thing I wanted to do was toss a JDM TT motor in it with new gauge clusters and such. I have been doing allot of reading on what is needed because im not really a car guy, but I am a super fast learner. :hpydance:

~~So a front clip is the best way to go then because it has everything?...is there anything else besides the front clip that I would need to complete the swap?? ECU, etc..etc...

~what about any special tools I will need besides the obvious, engine hoists, jack, and a good set of wrenches/sockets/screwsticks, and a few pry bars?

If you don't want to replace the engine anytime soon, then you willwant intercoolers. Consider them a required item. Don't waste your $ on a used harness...just buy a new one from COZ for $350.

Thanks Rizz for the info on the clips....im going to get into the market for one of those very shortly (within the next month or 2).

91zxtt--How would a used wiring harness be any different then a new one? They're just wires.......I'm tryin to keep the cost down so if there is no differnce in used or new,,,i'd prefer the used to save some $$$$$ flow......what ya think?

ECU should be included in the front clip.
You might want to invest in a new clutch, possibly flywheel, new driveshaft will be needed-might as well get one from Z1, any other performance parts you wanna put on the engine will be much easier to do with it removed from car.

obviously you haven't seen what a 9-15 yr old harness looks like after being baked in the engine bay after all those years.
