Am I missing anything in my TT swap parts list?

[roshenu]

So this is my list of parts + work to be done for my TT swap.
Please take a look and let me know what I'm missing

- Complete TT engine w/ stock turbos
- NA transmission with starter shim plate from Z1
OR
- TT transmission if the motor I'm buying comes with it.
- NA wiring harness
- Remapped ECU by JWT or Z1
- Stock intercoolers
- eBay intercooler piping
- Ramey Z intercooler piping mounting bracket
- Intercooler ducts
- Manual boost controller to start off and will save up for the new Greddy Profec electronic boost controller later.
- Should I get recirculation valves? If so, how do I install? And is there any additional recirculation hoses involved?
OR
- Should I get BOVs? If so, do I install it in the old location of the recirculation valves or is it easier to get the Z1 hardpipes with BOVs fitted on em?
- TT MAF
- TT A/C condenser
- NA A/C compressor
- NA power steering pump
- Oil cooler - Care to recommend me a oil cooler kit with all the piping/hoses and mounting plates?
- Stock TT Radiator
- Fabricate radiator brackets if necessary. Will it be?
- Replace radiator fan and shroud with electric fan kit
- Silicone coolant hoses + heater core hoses
- Z1 downpipes - Will they work with my NA high-flow catalytic converter pipes?
- TT clutch/flywheel combo, JWT or F1
- Walbro 255 fuel pump - Is this harder to install than the stock TT fuel pump?
- NA FPCU
- Z1 EGR elimination kit
- New style PTU
- Z1 PTU relocation kit
- Z1 PTU sub harness
- New throttle position sensor if needed
- Stock TT driveshaft or Z1 1-piece driveshaft (aluminum or platinum)
- Do I need new motor mounts?
- What kind of work needs to be done in regard to fuel injectors and fuel injection hoses?
- Do I need any specific hoses for the A/C?
- Vacuum hose kit. Anyone know how many meters of hosing I'll need?
- Is there any work that needs to be done with the idle circuit?

MAF will be fine with either NA or TT, they are the same
Fabricate the Radiator bracket, really easy, yes you need to fabricate or buy one premade, only $25
Only downpipes that will work with NA pipes are JDM down pipes, bend is different at about where it connects to the DP
Fuel pump, TT one was very easy to install, walbro is just a hair difficult
Trans you will need to shave off the inside for TT flywheel to not rub
You will need a NA shaft if you car was an NA before, they mount differently at the rear end NA is 4 bolt TT is 6 bolt
Motor Mounts are the same
You need at lest 370cc fuel injectors hoses are the same
Idle circuit, nothing is different

Going through your list, I think you are missing a few things, just can't think of them at the moment. I would also highly suggest replacing the knock sensor and KS harness while the engine is out. TT's like to detonate a lot more than NA's, better to have one fresh that can read when it is detonating. Have money off to the side, things will come up. If this is a JDM motor, look for the thread about them. At bare min, I would change the timing belt 120k kit, oil pan, oil pump, reseal the engine. Personally I would upgrade to newer style injectors. Well worth it. Things are going to come up and it will get expensive, most of us easily spend 5k plus on the swap, thats with doing the work ourselves.

Would it work if I got a Megan downpipe/testpipe combo and fitted it to my cat-back system?
And do you know if Z1 has the pre-made? A link if you don't mind?

Is this the driveshaft you are talking about? So that means I should stick to the NA sriveshaft? If not, what driveshaft will work? Again, Z1 has it?

You need at lest 370cc fuel injectors

Is this something extremely necessary to get up and going or am I able to finish the swap and then have the fuel injectors changed from 270 > 370 after a few months? And yes the newer style ones.
Or is it easier to do while the engine is dropped?

Thanks, knock sensor + harness added to list!
I already have the 120k timing kit lying around at home.
Oil pan and oil pump - added to list!
Full gasket kit - Ah damn, I feared this! Added to list although I'm afraid of how much it'll cost to install all of that! Would you know?

Thanks again! I really appreciate it

1. Read this http://www.z1motorsports.com/PDFs/NATTconversion.pdf
2. Read all the sections on this page http://ztechz.net/
3. As you will discover from reading the above two; not enough fuel = boom, so unless you really like rebuilding your engine multiple time you will need the 370 injectors before you ever start it up. Although if you re getting a JDM swap you should be getting the injectors with it.

Ok I'll make sure the engine comes with the new style 370cc fuel injectors
If it does, what else will need changing in regards of the fuel system?

[Re037]

tt ac lines are different, both high and low pressure lines. jdm tt ac lines are completely different than usdm tt ac lines also.

get new o2 sensors and spark plugs as well.

I suggest bde mounts and bde aluminum half moon plugs

a tt efi harness is preferable as some wires are longer to go around intercooler tubing (plus it has the extra wire to ecu should you decide to run a 3 speed tt fpcu) not sure if you need stock boost solenoids hooked up for mbc tho

plan extra $$$ for random misc things like vac lines, turbo coolant hoses.

I also suggest new chras and injectors

my jdm clip was running when I first received it (turned it on, ran for 5 minutes to make sure everything works)
8 months later with the swap done, i crank it to find I now have 2 dead injectors. should of replaced them when I had the plenum off the first time. now I get to do another plenum pull...

im about $8k in btw, most of it is just replacing old worn parts. barely any upgrades. just sz flywheel +clutch, cheap godspeed intercoolers (stock was heavily damaged from shipping) and blitz sbc id

[roshenu]

$8000 with minimal mods! Phew, I can admit, I don't have all that money lol
But I'll still keep pushing to grab my minimal estimate. Then multiply it by 1.5 to see if I can actually afford it.
What did you mean by 'new chras'?
The TT A/C lines, are they available for purchase at Z1 or CZP?

Anyway, does anyone know what this does?

Its a recirculation fitting for the HKS BOVs. Are they meant for people who already have BOVs. If the BOVs don't let air out, and recirculate it instead, isn't it smarter to sell BOVs and go with stock recirc valves?

Roshenu, I highly suggest that you read the two links I provided beginning to end, because there is so much information you need to truly understand what you are getting into, it would take pages upon pages in this thread and it still wouldn't combine all of it. This is not a cheap swap, and you will need ~$5k before its all said and done if you want to have a reliable tt.

I highly agree to this^^^^

You really need to find out what it takes. I was down almost 6 months doing this swap, and spent 5k-7k when all said and done. Some other guys down more. My advice, do not cheap out on parts. Buy oem for belts, pulleys, sensors, etc. You will end up buying them again cause you will have issues with it running. Its expensive, but worth it.

Like most people will state, unless its a 2+2, have severe sentimental value to the car, or you just plain crazy, it would be cheaper selling what you have and buying a TT from the factory.

[nissanfreak12]

I was reading into some the previous post some more, are you doing the work yourself or having a shop do it?

If you have a shop doing it, you will easily, and I mean easily spend 10k+. Just a thought.

[roshenu]

Yea I did read em both and I tried making a price add-up for everything in my list^ and came up to about $3500 without the motor, intercoolers and piping. Estimated maybe $6000 after everything. Who knows what can add on to this...
And no kidding, I don't have that kind of money right now. I will by next summer, but again, its a lot of money I would be dumping into any car at 20 years of age.
I'll enjoy my NA and buy a TT maybe towards the end of school

Thanks a lot for all the help and enlightenment haha

If you've done the math and searched the market you've seen that it really is cheaper and muuuuch easier to just sell your NA and buy a TT, not sure where you are but in Texas you can find a superclean near mint TT for $10-12K so take the price of your NA (which if clean could fetch 4-5k) plus the 6k or so you'd spend on the TT engine and all the other stuff plus the freshening up and you will land right around 12k.
