I have owned my 92 NX1600 since December 1992. Since 2001 or 2 I've been thinking about a GTi-R swap. I've actually purchased two NX2000s and a 200sx SE-R with the thought of a swap but never followed through on it. A year ago I found out about a GTi-R clip that had been purchased a decade ago for a project that never occurred. It has been stored less than ten minutes drive from my house that entire time. Last fall I bought it. This engine looked pristine - each of the heat shield bolts came out perfectly (just an example of the great shape of this engine). Compression is 150, 150, 150 and 145. The engine and ECU are stock GTi-R and that's radical enough for the next year or two. Yesterday virtually everything was completed and now it is time to break the engine in. The SR and GTi-R community stepped up to ensure that I was able to complete this. Specifically nxpartsource, lynx, fastnx, and jkho. Greg at G Spec stepped up and helped me out by slashing what could have been a month long project delay to a few hours. Major props. Thanks to Mike, Jeff and Wes for their inspiration and positive support.
Thanks to Scott at Can-Alignment http://www.canalignment.com He's racecartech on the SR forum! I cannot say enough about his creativity, professionalism and ability to take a challenging project from start to finish. Scott has done my alignments for a few years now - this was obviously a much larger project. March 9 to 16 was 12 to 16 hour days - and a number of evenings and full weekends since then. What a great shop!

The transmission is a 5 speed LSD from an Infiniti G20 P10 -- update, I got the receipts for the tranny and it's a 99 P11 -- with the case strengthened. I've been looking for a P11/B15 since I started purchasing parts for the build. With the mechanics of the build almost complete I located a P11 transmission as a spare and it will be ready when I need it. A lightweight flywheel and a Bully Stage Four clutch finish off the drivetrain.

I am anticipating losing a few seconds at each of my favourite road courses!

The GA16's transmission shed a few teeth last season and that was the prompt to start the swap. We also found that the throw out bearing was toast. An Infiniti G20 (P11) has been mated to the SR, with the transmission housing strengthened for the extra HP.

Finding a P11 or B15 transmission was a challenge. So when a second P11 came available (less than two hours away) I bought it as my safety! The nice thing about the Infiniti transmissions, they easily wire to the NX1600s digital dash. Right now the speedo gearing is off - showing 55 kph it's actually doing about 110 kph. So it's almost like it's reading in mph! In fact, when I switch the digital dash to MPH and multiple the shown speed by three, it's almost perfect with KPH. Example, when it shows 40 mph I'm actually doing 120 KPH or about 75 MPH.

Water temp, Oil Temp and Oil pressure gauges have been added.

Scott discovered my secret tricks to keep the car's weight up high so that I was still able to stay in Touring 3! LOL!!!

Placing the FMIC up front to consider placement.

I like this!

We had to cut out a minimal amount of material to fit the intercooler piping in place.

Checking out the fitment

While there was lots of room with the GA, the SR certainly required a bit of finesse to get in place.

Bully was my clutch choice. They are a Canadian Clutch manufacturer and an avid supporter of local motorsports. I had a Stage 3, 3 puck in the previous set up and was very happy so no question about this project. A Stage Four clutch with an Aasco Motorsports flywheel.

Which one will I bring to

? In the fall I picked up a 92 NX2000 that I'm using as my winter car.

Couldn't leave Can-Alignment without a corner balance and alignment!

Ford, a regular CASC-OR Time Attack competitor, was in on a regular basis to help out. We were also regularly checking out Scott's new widebody 240SX. My car is done and Scott can move on to other projects.

I think I would upgrade that little exhaust the first chance you get. I would think it will make for some really high EGTs, restricting boost and I don't know what else.

Nice placement of the FMIC and the air filter though right where I have mine too! I really like where this car is going!

Jere, Thank you for your comments and suggestions. I appreciate it and absolutely hear you. If I change the up and/or down pipe it will cause me to be bumped up another class, because I'm already very close to the limit for what I'm hoping my new class is going to be in our Time Attack series. I'm also out of $$$.

But in one or two years ... hard to say. I've already got a lead on some cams!

How does your hood vent look from a bird's eye view?

Hi Jere, I'll get some pics posted to give you a better view. It's a functional but ugly approach - I sketched it out and then had some high school kids work on an old hood (I have three) in their shop class to see if it would work. It does. First opening is just behind the rad and the next is just behind that/in front of the valve cover. They welded in some louvers under the hood.

wow! nice project!! what clutch assembly did you use?

Gabby, I've got a Bully Stage 4 clutch with an Aasco lightweight flywheel bolted to a 99 Infiniti G20 LSD transmission.

I haven't been online much do to way too much to do at work and then a large time commitment as my oldest daughter got married. Plus, after an outing at Shannonville Motorsports Park where we were putting down some decent times and staying pace with Corvettes on the quarter mile straight (the dragstrip is built into the road course) and in which my youngest daughter, Katie, beat my best time. I'm proud of her but it was father's day so she did her best to show what a good dad I am!

However, we broke the passenger side axle mount. I'm now trying to source a GTI-R transfer case mount that we can fabricate to hold the SR20 axle mount. Seems like I need that kind of strength. So when that and some boost leak issues get sorted out, the project will be back on track again!
