Hi,

 

Just gathering info at the moment, have an n/a auto at the minute but going think Iam going to put a TT in with a manual box, what would you say the cost would be? going to do the work myself.

 

Do I need the tt loom, ecu, prop shaft? are the engine mounts the same and what things needs to be altered on the car to get the engine in?

 

Thanks everyone,

 

Mark:biggrin:

just sent them a message on ebay, will give them a tinkle tomorrow, what does the clamping force need to be in order to cope with the TT engine?

he sent back this - NSK2017 for the 300ZX turbo Z31 1983-1986 VG30T - this is whats fitted to my NA???? cant tell me what the clamping force is as he doesnt know...... ffs dont know what to do now....

Legrath,

 

Just in the middle of a LWB zxTT manual swop to a NA auto convertible, could sure use your help, is there any chance you could text me on 07515 546 494 & I'll call you back?

 

Cheers

Unless the car is something very special it really does make much more sense to just buy a TT manual in the first place.

 

I've worked on 2x NA>TT conversions, but one was a Convertible (TT version never available) an the other had a lot of money already spent on its bodywork to make it worthwhile. Its more popular in the U.S where 2+2 or Slicktop owners will convert their NA's to TT becuase they were only ever available there as NA in the U.S.

 

But if you insist then keep an eye out for an Accident damaged TT manual, or a Rotting UK model - its easier to use a complete Donor vehicle than source indvidual parts.

 

To answer your questions :

 

Propshaft - You need Front half from a TT Manual and keep your NA rear half.

 

Loom - Your NA loom is fine. No boost solenoids, they can be wired in but most people just fit a Boost controller.

 

ECU - Yes you want a TT ECU or chip your NA ecu with a TT chip.

 

Engine Mounts - Same

 

You will need :

TT Conversion

TT Engine

TT ECU

Intercoolers and pipework

TT Radiator

 

Manual conversion

Gearbox

Clutch

Flywheel

Front prop half

Bellhousing shields

Gearshifter support bracket

2x rubber Gearshift faitors

Clutch Pedal box

Brake pedal box (or cut your existing brake pedal)

Clutch Master cylinder

Clutch Slave cylinder

Clutch hydraulic pipework - or custom 1m Braided hose with M10 fittings

 

You will find there are no brackets for the Intercooler pipework, so you will have to fabricate these (or cut them from the TT and weld in). Its mainly the 2 brackets either side the radiator you will find you need most. Other option is to fit an aftermarket FMIC which uses custom pipework.

 

The NA and TT radiator lower support brackets are in different locations. Ideally you would want to cut and reweld them in the correct place.

 

The TT alternator is higher amps, so you can swap that although not essential.

 

You will need the cog from an NA Manual speed sensor to match your NA rear diff. Gear cog is available separately from Nissan dealer.

 

NA and TT fuel pumps do differ, but the NA pump provides enough fuelling.

 

You will need to swapover the PAS bracket from your NA engine to the TT, in order to fit your NA PAS pump.

 

umm....This is of the top of my head so I may have missed something but I think thats everything, If i rememebr anything else I will add it to the list.
