***Topgunz ROTREX C38R Supercharger Kit***

SirReginald

Does anyone have a pic with this kit on a G37 without needing hood pins? Every build I’ve found so far has had to replace the latch with pins because the engine is higher up than on the Z. The kit looks awesome but that’s the only thing holding me back! TIA

I ran the super street clutch from Zspeed and it was very nice but I am pulling to much tq and it would slip so I went to the 6 puck from Zspeed …. There is defiantly a learning curve but once it broke in fully I don’t have too much trouble with it for daily driving …the super street clutch should be fine for you with the supercharger with its tq range and how it build power.

Right on, I ordered the stage 3, clutch install kit and the CMAK. will be installing this weekend long as it gets here when it's supposed to. Should I install a new CMC at the same time? Never really got a answer about that from Joe. Eventually I'd like to get a RJM pedal and HD CMC, but I couldn't even find a HD one for sale. Car has 35k miles, clutch fluid looks kinda dark tho.

RT Tuning should be receiving my kit soon. Planning on having them swap out the Ace Kit for the new Rotrex Kit but not sure if I will need to upgrade my injectors. As of right now, I'm shooting for 625whp. I was able to hit 540whp with the Ace Kit so I'm hoping with the Rotrex that I will have enough injector.

1050's and the 450 should be able to get you to 625. That's what I ran and I was good until I got to 650whp and then I needed to upgrade both pump and injectors

I have the Xtreme Twin Plate Clutch installed in my Z. Rated at 885 lb-ft.

It can be a challenge to take off quickly in 1st gear in a smooth manner due to the sudden on/off clutch engagement feel (or lack thereof) of the standard pedal. I'll have the RJM AFP Clutch Pedal System installed later this summer. Hopefully that helps to provide for a smoother 1st gear engagement from a full stop.

edit: plus, it's kinda noisy in different ways. this is my first-ever aftermarket race clutch, so it's new to me that a clutch can be making so many weird noises - but quite normal I'm told.

Anyone running a brushless pump? My tuner is suggesting that's what I go with.

Finally scheduled a week off of work, will be installing my kit next month! Got the zspeed stage 3 clutch/flywheel and cmak installed last weekend, got it done in 2 days, not bad considering i had never done a clutch before and doing it in my driveway on jack stands. My FI oil cooler just shipped out, buying injectors and fuel pump next week.

I think that depends on your power goals

Looks Awesome!
I can only hope that my kit comes out just as well!

Very nice man, I finally have everything needed to install mine. Taking next week off from work, soon I'll be your twin. Except my pipes are red, had a red z when I ordered my kit, got a black one now but I think it'll still look good. Went with the DW 440 brushless fuel pump per Eugene's recommendation.

Anyone running an oil cooler kit? Any suggestions?

I’m running a 24-row z1 kit and it’s barely enough. Oil temps in 90 degree stop and go traffic hit about 235. I just got back from driving up mountain passes in 60 degree evening weather and I couldn’t get it higher than 220.

JVerge5363

Since my car is not my daily, it's very rare if I ever take it out in 90 degree weather. During summer months I usually take it out in the evenings when it is cooler out. I'm debating between the 16 row or 24 row.
