Hey guys I’m new here to the forum. I just purchased a Sentra Nismo and decided to buy a lot of performance parts on Black Friday. Here pics of what I bought

I will let you guys know how everything goes and update as much as possible. My next upgrades are going to be a front mount inter cooler, down pipe, TFR turbo upgrade, performance clutch and flywheel and a tune.

nice list: just be careful of that style of diverter valve upgrade, we have found that the plastic casing can crack when reinstalling the new spring and the plastic on plastic seal it uses (the oem part) still lets boost creep past!

Thanks! I’m going to try my luck with gfb diverter valve and if that fails I’ll probably buy the turbo smart diverter valve. I’m just waiting for parts now.

Any updates here? I’ve got a Nismo, curious what you think of the mods since they are somewhat prevented from much hp gain by the ecu without a tune...

The MR engine responds very well to mods. But obviously a tune is the way to go. I don't have a B17, but my Juke is virtually the same car. The exhaust is always the most restrictive aspect, but if you go full exhaust and a tune, you will see solid increases. I am around 300 crank Hp on my Juke with no turbo upgrades, and I could go more if I honestly wanted too.

The v2 mr and the v1 mr are not the same in any way as far as tuning goes. the turbo system is completely different. The tuning is completely different. The engine management is completely different. The compression is different. It is extremely difficult to even get a tune for a b17 turbo. I would be interested to know how you got the crank horsepower? Also how, on a stock turbo you got to that claimed number? The oem v1 turbo will not make over 250 peak horsepower unless your on a really skewed dyno. And even if you hit that number, the graph would look like a mountain, which is not efficient.

Full 3 inch exhaust turbo back, Custom intercooler and piping, custom clutch, Stage 2 ECUTek tune, 22lbs of boost. It really wasn't hard. I have been helping push the limits of the MR and TD04 turbo on these cars since I got my Juke in 2012, though I stopped once people started doing turbo upgrades. Dyno graph is clean, the car was professionally tuned by John Visconti at PSI Proformance (though it really needs a retune).

Also what is the compression if it isn't 9.5:1 ? I was under the impression that the engines were damn near identical. Power output from factory seems to be the same. The only thing I know is different is the transmissions.

the V2 mr uses a 10:1 compression ratio. Different piston design. The entire engine is redesigned. The main castings are the same but that is about where the similarities of the engine itself end. The turbocharger is 1/2 the size of the v1 turbo. MR16DDT V1 vs V2 Turbo Comparison - YouTube

It also uses an all electronic boost control system, and has a full egr system, which makes it so the engine needs to be removed to change out the downpipe: How V2 MR16DDT Boost Control Works - YouTube

egr system can be seen in this video: V2 MR16DDT Big Turbo Episode 3 - YouTube

Thanks for the lesson, had no idea so much changed since I stepped out of the MR game. Definitely good to know, so I appreciate the info. I've kind of fallen back into the Z world so my Juke doesn't get a lot of love anymore (though I ordered a short shifter for it finally lol).

But yea right now, my Juke on the stock turbo and wastegate is probably at about 290 crank, maybe a bit more. I've been thinking about the Mambatek turbo upgrade to crack 300 but my Z is taking up most my money right now.

Was a daily for a long time. It got hit while in front of my house and since it was repaired I haven't driven it, but once I get some fresh tires she will back on the road. It will go back to being my daily once my daughter is born so my wife can have the Pathfinder all day. I just ordered a short shifter and have a brand new Siebon CF hood ready to go on (stock hood rusted real bad for some reason). Car rides perfect, very easy to daily especially in normal setting.

22 is about what most people run with a tune. Tiny turbo needs a lot of boost to do anything. The 400 horsepower Juke I built is running 24psi on a way bigger turbo. Keep in mind it is only 1598cc's. Takes a LOT more pressure to make anything happen on an engine that small.
