Greetings Nissan Performance enthusiasts. I've been known for many years as Irie Judah, Ras Irie or simply Irie. With that, you can understand the compounding of Irie & GTiR to form GTiRie.

In February of 2016, due to a unique set of circumstances, which in retrospect can only be described as destiny, I was fortunate enough to be in the right place at the right time, to be informed of (what we in T&T know as) a Nissan B15 which was for sale.

It was a 2002 Nissan Sunny FNB15 4WD which had been previously modified with a Nissan Pulsar RNN14 GTiR Engine & drive train, stripped of all non-essentials and had been drag race prepped, doing 11's by the then owner who at that time had stepped up to an R32 with a 2JZ transplant and was selling the car.

Sounded really good and I was immediately interested, thing is, it was an "as is, where is sale" and all the goodies had been either used by the owner on his new project or sold off. Car was down for some months, immobile, had no Turbo, no ECU or management of any sort, no MAF sensor, needed rewiring, I was told the gearbox was barely alive, noisy and unable to select all the gears, no gas tank as a fuel cell was being used.

Looked like I came a lil late to the party, but all was not lost. One of the circumstances of that unique set I previously mentioned was the fact that the Mechanic who had done the GTiR conversion and the vast majority of the race prepping of the car was the Mechanic at the Performance Shop I carried my 2004 Nissan FNB15 for servicing in Feb of '16 and he, as a result of the car being 4WD and the after market suspension parts I was installing, asked if I purchased those specific parts for racing. We hit it off as fellow gear heads and discussed possible performance mods and my love of 4WD. I told him that I had intentions of one day ditching the QG18DE I had installed (car came with QG15DE) and stepping up to a Pulsar engine & drive train transplant.

That is when he mentioned that a customer of the shop had exactly such a project car for sale, at a really good price, which he would get further reduced if I were interested. He was able to give me the history of the car as far as the modification and multiple gear box crushes, rebuilds and replacements went and indicated that I had his full support to get the car up and running.

Even though I was aware that many parts were missing and lots of work was required to even get the car running, I still saw potential. The buy seemed somewhat risky, I had never seen the car run and had no idea what I was really buying. The previous owner used it for racing, the engine could have been really beat out from that NoS and a GT35R. But I was given the assurance the engine was mint (eventually had it pressure tested, 150psi all 4).

B15 parts are about the easiest and cheapest to get in T&T, both new and Japan used as the B15, Almera, N16, AD Wagon & Wingroad all use many compatible parts and are all popular models here, we also have a thriving Japan used parts industry. However, 4WD B15 parts are a completely different story. They are almost exactly the opposite regarding availability and price. GTiR parts are even harder to find locally, needle in hay stack.

Despite those factors, I still saw potential and the price was the deciding factor (less than a JDM GTiR engine & gearbox online), the car was legal for road use and I already owned a car of that model for the previous 9 years and knew the car very well from lots of tinkering. Having quite a few years of doing light maintenance of vehicles I owned, a passion for motor sport from childhood, and various academic and practical mechanical Courses including City & Guilds MEEET, I approached the task as a project and challenge.

As far as parts were concerned, I knew the local search for what was required would be hard and long and when the parts were found they would be pricey. But on the bright side, I know almost everything is available on the internet and having years of occupational Import/Export experience was a big plus which gave me a sense of confidence in my ability to find what I needed and have them shipped to me, easy peasy.

So, I was in. purchased the ride, assessed what was needed to get rolling and started the search.
GTiR gearbox, ECU, harness, MAF, injectors, injector resistor, ignition module, distributor (all gold). 4WD B15 gas tank, turbo, fuel pump, fuel pressure regulator, plug wires, rewiring.

Took me about a year to locate all those hard to find parts, some locally and some online, the gas tank was the hardest to locate. But as promised, I received the full support of the Mechanic who has become a friend, to get the car mobile.

This is my 2002 Nissan FNB15/GTiR project. Late 2017. A while after we got it up and running.

I know this might sound a little crazy but, after many hours of research and drawing from the experiences of Taarks Engineering & Norris Designs, I decided I was going to Twincharge my project. What is Twincharge? Twincharging or a Twincgarger? You might want to research the Lancia Delta S4 https://en.wikipedia.org/wiki/Lancia_Delta_S4 the Nissan March Super Turbo http://tech-racingcars.wikidot.com/nissan-micra-ek10-super-turbo https://en.wikipedia.org/wiki/Nissan_MA09ERT_engine and the VW TSI engine https://www.autoevolution.com/news/volkswagen-tsi-engines-explained-60143.html

Put as simply as possible, it is when both a Turbo and a Supercharger are strapped to the same motor. When properly engineered the Twincharged motor will have the best of both forced induction systems while eliminating the drawbacks of either. That is to say, substantially increased low end torque (with zero lag) supplied by the Supercharger and larger mid range and massive top end from an oversized Turbo. To be of benefit the Supercharger must be a positive displacement blower i.e. Roots Type or Twin Screw and not Centrifugal. The crucial aspect of Twincharger tuning is the change-over point.

Because of it's physical size, displacement, the fact that it can be rebuilt and the easy availability of parts, even upgraded seals and bearings, I decided on the Mercedes M62 Clutched Supercharger manufactured by Eaton.

Picked up one on ebay for $180, with a little damage to one of the mounting tabs and a cracked front cover

The damaged tab. The scribe is the mark where is to be ported.

we never get the cool toys here in the States, lol. people have been trying to figure out an awd sentra for years, and they are already out there!

I am going to move your post to the "Members rides and project cars" section, where it really belongs.

Great introduction and build tho, and very interesting, and interested in seeing how you make it all work!

Thanks yogi b

I believe the water/meth kit an essential mod which is very effective in keeping in-cylinder temps at a manageable level and imho should be used by everybody with aftermarket or upgraded forced induction. But I intend to push it close to the limit, so its an essential for my project.

That I am one of the few using it, comes as a genuine surprise to me.

I intend to step up to the AEM V2 Controller which features water/meth injection based on fuel injector pulse duty.

More pics to come.

Glad you like the project.

Thanks for the best wishes.

Thanks shanover

This build is really a dream come reality. I have always felt considerably more in control of these econoboxes with the 4WD system. Had a much too easy spin-out in a FWD B13 quite a few years back, it was most likely due to poor vehicle maintenance but I'm also sure that the 4WD counterpart in the same poorly maintained condition would have been a lot more stable on the road due to better weight distribution and drive from all 4 wheels.

Sorry to post the thread in the wrong section.

It took some effort but I'm glad the intro/history gets your approval.

I will post progress as it happens.

for example;
you have drag bars

The measurements for the 240SX Tie Rod happens to be appropriate for my intended use and it has some adjustability and a mounting bracket will be fabricated or modified to provide connection point for the rod from the sub-frame mount location. Easy, cheap, custom rods, not too difficult if you have a lil skill

I can appreciate all of the hard work, effort, thought, and skills that are going into this build, you are taking on something that will be a first, that I am aware of, of both a roots type supercharger, and a turbo incorporated into an econobox, lol. of course if we didnt love the cars, we would never justify the amount of money we dump into them!
Also, props for finding everything you need! I still have a pile of parts I need to get put on eventually!!
