New NC 1.8 build from Greece
 

After 5 NBfl's (the 3 were turbocharged) I decided to try my turbo luck on the NC building a custom kit from scratch using stock internals.

I am going to use a TB28 from Nissan GtiR equivalent to the gt2860rs and will try to stay to 0.6-0.7 bar.

For fueling I am using the ev14 550cc injectors working great with the OEM ecu like the stock ones. Perfect idle and afrs.

So far we are here.

I hope to see more Turbo NCs soon.

You need to get with Joe at Dynotronics for a 2.5 when you bust the 1.8 ;)

As far as I understand, the 1.8 is just a smaller-bored 2.0 block, so a 2.5 block is only a bit taller, so it would easily pass any visual inspection, if that is a problem where you are.

I will be getting a 2.5 swap from Joe soon. The Fab9 EFR turbo kit is coming out soon and then you will definitely start seeing more turbo NC's.

Well I am located in Greece and the 2.5 engines are extremely rare and expensive so I am not interesting in swapping.

We 'll see how it will handle the boost the poor 1.8

The manifold looks good! Are you going to shield the alternator at all?

Well, when the time comes, Joe has said that he can ship a built 2.5 to you for cheap, so you don't need to worry about 2.5's being rare and expensive where you are at.

Yes I may put some insulation on the 4th runner.

And here it is fitted on a spare engine in the shop

And there it begins.

Here is one first test with some basic tuning and very safe ignition timing @ 0.4bar

And now MOAR boost @ 0.6bar but with still very safe afrs and ignition.

A small update:

So far the stock ecu seems to handle boost great. The load measurements via MAF are precise and the afrs are solid!
I even added the zeitronix map sensor to the original ecu with the proper calibration and now ecu can recognize boost succesfully!

This is a very friendly to boost car and I am wondering why so few people have tried boosting it... The engine is responding great and I think that it can handle more torque than the stock BP or B6.

Such a shame we have no feedback from other NC turbo owners.
Any comments on the setup are highly appreciated!

Because we are cheap and the majority of us don't want to spend the cash required to get a NC.

How much does a 06 NC costs in US ?

More then NA/NB's. I think they are starting to drop below 10k USD, but I honestly don't follow the NC market to much.

Here are dirty cheap. You can find for 5-6k€ the early ones.

Also the turbocharging is waaaay cheaper than the na/nb. There is no need for gauges wideband(stock NC sensor) and boost can be monitored via Torque app with a 7" tablet
No need for extra piggyback or standalone ecu and the stock exhaust has a decent size of 2.36" (not ideal but not too bad)
Also the stock FPump can handle 300hp so a walbro won't be necessary for anytime soon.
I am also suprised from the clutch. After on month it is still holding strong, but I don't think it will last for much long.

Today I upgraded to 3" maf intake. Wow what a difference! No more check engines at WOT and runs lovely at 15psi . Before I was maxing out the MAF at 12psi throwing a CEL.
It took me about 3 reflashes to get it right and now it runs like before.
Also I managed to put some extra protection with richer afrs and safer timing in case of overboost and overheating , just in case.

I took it for a mountain spirited ride and it was a blast to drive. I am very excited of the potentials of the stock ECU it gives really no limits to the tuner.

are you self tuning it? what with? ecutec?

Yes self tuning with Mazdaedit. I have tuned many other NCs here and a tonne of nb's and na's with standalones and piggybacks.
