one more Intercooler or after market set upIntercooler plumbingIntake plumbingTT radiatorTT fan shroudTT oil cooler and hosesTT A/C condenser and A/C linesRecirc valves or BOV'sModified EFI wiring harness (TT harness on this motor is for RHD)TT flywheelTT clutch and pressure plateNew oil, fuel and air filtersTT fuel pumpTT front fasciaModify idle circuit plumbing to attach to intake hose.Fabricate mounts for IC plumbing, radiator, and oil cooler.Modify manual transmission bellhousing for larger flywheel

Honestly that is all you need but like the parts 300scotties said, if you do it you really need his list. The harness has to be modified but will work, computer bieng out of an auto makes less power (280hp). The trans bellhousing will have to be ground out on the inside and the starter shimmed. You will also need downpipes and a boost gauge.... the list could go on forever. You should have bought a whole clip for $2000 more and had everything minus fluids and hoses. Good Luck...

no. DONOT GIVE UP.

Go on google and do a search for "300zx JDM Front Clip" or go to a Z specialty company. Look for a 300zx Twin Turbo FRONT CLIP. a Front Clip is just about everything you could possibly need for a TT conversion. and yuo can get one for as cheap as $2,500. That's what I'll be doing in aobut 8 months, myself.

Now, you can either pay a shop about $5,000 more to install it.

OR, you can park the car for aobut a month and do it yourself, but only end up spending about $400

[DustinZ]

email me at [email protected] I have clips.

[idontknowiguess]

if u would of looked at the link it would of showen u im getin hafe of that stuff and y would i need an engien gasket set

[gpelite]

I have a question on the topic as well, in the swap can u just us an N/A manual trans and be done with the transmission?

What besides air fuel ratios and boost solenoid control does the TT ecu offer the setup?

Can you use an N/A ecu in a TT with just a fuel computer to change air fuel ratios or what? Do you need more??

[27RB240]

Sorry but I might as well ask....Do you need the rear subframe also? or would the NA be good..And mounts, does that mean new TT mounts? which i hope so.... and the crossmember.....or would you need a custom driveshaft or anything of that sort...this is some good info guys!!!Thought i might as well ask..I have been searching on this also....

[DustinZ]

Ok. maybe this info will help. First, you can use the n/a trans but the tt and n/a have gifferent sized flywheels and clutches. You would have to grind out the bell housing to fit the larger tt flywheel and shim the starter into correct possition. The N/a and turbo ecu have alot more differences like a whole different fuel map, and ignition retard. As far as rear subframe goes you can use the n/a subframe and diff, it has 4.10 gears which some tt owners like to switch to. The R200 in the n/a's is not as strong as the r230 though. You can install a r230 into the n/a subframe just as well using stock n/a axles (tt axles are different spline). Drive shaft, cross member and mounts are the same except if using the r230 there might be slight differences in driveshaft length. And for IDONTKNOWIGUESS he needs alot more stuff to complete his swap than he thinks. Anyone going this route should first buy a clip from a reputable dealer and also I would recomend buying a usdm tt engine harness instead of modifing the jdm. A clip will come with full piping, intercoolers, dump pipes, mid pipes (sometimes) etc... It is important to do the research before jumping into these things.

ok...I have done this swap to my 300zx successfully and it runs great. I bought my JDM front clip from http://www.venus-auto.com DONT think about doing this swap without a full front clip. Sourcing parts individually would make you go broke. The front clip has everything you will need. But you also must get new gaskets, sparkplugs, timing kit, wiring harness, clutch and I highly recommend new turbos while the engine is out. There is nothing worse than guessing that the turbos are good, dropping in the engine and then a month later having to take the whole thing apart again. Do it right the fist time. I have links to my swap if anyone is interested. I can answer questions. Shoot me an email and I'll try to help ya out...

[kevinarich]

You guys make it seem like its so hard to change a motor out and add a front mount. If you want to change the car to TT and keep it all factory then yeah you might need the clip otherwise all you need is some electric fans, a front mount, new turbos, boost controller, stillen pipe kit and some downpipes. You dont need all that other crap. This way you get what you really want not just a stock twin turbo.

[evildky]

most poeple keep it stock at the time of the swap to make things easier on themdselves and less cash outlay on the front end, but with proper knowledge and experience, I'd just get the bare motor with turbo manifolds, and add microsquirt custome harness, edis and big fatty turbo's with custome piped sidemounts, but thats me

How many NA to TT swaps have you done with just electric fans, FMIC, turbos, boost controller, and a stillen pipe kit?

[kevinarich]

Im simply saying that you dont need to convert a twin turbo to the exact specs that Nissan did. It isnt necessary to change the everything thats different. Yeah I know I left out a few things but not much more. Stand alone or the stock ecu. The clip isnt necessary.

BUT LET ME ASK YOU SOMETHING IF I KEEP THE R200 AND DO THE MODIFICATION NEED IT, WILL IT WORK FINE OR IT WILL GIVE SOME TROUBLE I LIKE SMOOTH SHIFTHING WHAT DO YOU THINK WILL IT WORK OR NOT THANKS
