Some of you guys may have been following my other thread about the Tomei install and know that the thought of larger displacement was always in my mind. Last week marks the day where the rubber finally hit the ground on this plan. I really want to thank Adam and 1cockyz for initially talking to me about this project when I was planning things out. My initial build list was quite simple as I didn't want to do something too extravagant, but it didn't take too long for it to get more elaborate. Here is the initial list that I settled on that came out a few weeks of research and chatting, some of these parts are from my current car but I'll include them for completeness. It includes all the components from the point of where air enters the filter to the exit from the Y-pipe, as those affect performance.
-Apexi 80mm filter (ported to fit the below item)
-Z1auto 3" MAF
-Samco induction hose
-Cosworth Intake Plenum
-Nismo High Compression Cylinder Head Spec2 with 3angle job
-Nismo Valvetrain
-Nismo VTC gears
-Tomei 280/272 camshaft
-Cosworth 100mm head gasket
-BC bRod 86.4mm stroker kit with 9.2CR and 100mm pistons (wanted the 88mm one but it was back ordered for 3-4 months)
-Darton MID sleeves
-ACL race bearings
-ARP main and head studs
-Nismo Oil Pump
-Tomei V2 Headers
-Ichiba Test Pipes
-Motordyne XYZ pipe
-Fluiamp Dampener
-Unorthodox Flywheel
-Walbro 195LPH Fuel Pump
As I was getting ready to leave to Asia for a 2-4 weeks business trip, Zcargarge wanted to take this opportunity and bring my car in to get the ball rolling. After reviewing the aforementioned list with Rob@Zcargarage and Dave@Rebello Racing (I'm sure many of you guys know who he is), Dave and Rob wanted to take this oppurtunity and build something they would be excited and proud about. They've built countless numbers of big powered FI cars but never one that was all out NA, therefore they asked me if I wanted to embark on a project with them. Who could say no to such a chance? So yesterday I dropped off my car with a deposit for them to get going on this project by next week. So far here are the parts that would go into my car, I'm sure things might change as he models my engine.
-Apexi 80mm filter (ported to fit the below item)
-Z1auto 3" MAF
-Samco induction hose
-Cosworth Intake Plenum
-Rebello Custom Stage4 (not 100% sure what is involved but sounds like a 5 angle job and some porting/grinding and polishing, I'll get more information when he is done). He retains stock diameters on the valves and is able to outperform the m2race ones (4cfm less @ .500" 20cfm more @ .200"-.300" and 6 to 8CFM everywhere else). He is contemplating a 1mm over stock on the intake as well, but he has to model the engine to know if it is worth while.
-Supertech Single spring valvetrain
-Rebello custom grind camshafts, this would also be created based on the modeling.
-Cosworth 100mm head gasket
-BC 88mm crankshaft. Rebello actually had one in his warehouse.
-JE 100mm Pistons
-Manley Turbo Tuff connection rods
-Darton MID sleeves
-ACL Calico coated race bearings
-ARP main studs
-Nissan HR head studs
-Nissan Revup Oil pump
-Tomei V2 Headers (he'll see if these are good enough for my car, i really hope so)
-Ichiba Test Pipes
-Motordyne XYZ pipe
-Fluiamp Dampener
-Unorthodox Flywheel
-Balancing of short block with pulley and flywheel
-Blueprinting of long block
-Walbro 195LPH Fuel Pump and/or bigger injectors
-Port match and polish on the parts from the air filter to the intake collector to match the cylinder heads, including the throttle body.
-Tuning wise, I'm going to stay with Osiris flashing and get it tuned for 91, 100 and possibly E85.
I'm sure everyone will ask what the goals are for this car, but truthfully I didn't really put any numbers to it, but if I have to put a number to it then 75whp and 100wtq more then what I dynoed at Zcargarage. With that said, here are the current numbers and upgrades that are on the car for the number goals above to make sense.
The above dyno is including the following upgrades. I originally went to another shop to get my baseline and install done so I don't have a baseline on the same dyno. The lowest numbers reflects the baseline when I brought in my car to Zcargarage. However talking to Rob a stock VQ35DE usually dynos at 210-220whp - 200-210wtq for a MT.
-Jim Wolf Tech Popcharger
-Stillen Z-Tube
-Motordyne 5/16th Spacer
-Motordyne MREV2
-Tomei Procam 264in/264ex
-Tomei Expreme Headers V2
-Ichiba Test Pipes
-Motordyne XYZ
-Osiris Tune
The highest number seen above was a quick tune that only involved fuel correction, so there is a lot of room left for tuning. There were also certain components that I wanted Zcar to retune for, but never had the chance to do so. I believe if everything had a final tune with the additional parts I would see a minimum of 10whp/10wtq (cosworth plenum, 3" Maf, and samco tube were not yet installed). However prior to tearing everything out of my car, Zcargarage will tune my car one more time to see how the cosworth performs on my car, but not with the 3" MAF. I'll shoot him an email to see if he can. This would be a good thing for people to know as it is a cheap upgrade.
I'm also taking this opportunity to do a few extras that have been bothering me, since the car will be apart.
-Swap out my radiator hose to black silicone
-Anodize my timing cover to Matte Black
-Anodize my strut brace to Matte Black
-Maybe paint my washer fluid and coolant tank black.
-He also mentioned painting the radiator mount black, but I'm not sure about that yet
-Change out my CD0001 transmission to the latest CD0009 (i have a real tough time getting into 2nd and 3rd pass 5k rpm, with occasional grinding going into third)
Here is how the engine bay looks as of now, so you guys can get an idea.
Good thing is that both Rebello and Zcar can work in parallel on my car since Rebello has many bare block that he can start doing the more generic things that don't require my longblock to be there. An exciting thing about this project is that my engine, before and after, will be strapped on to his bench dyno for numbers. My cylinder heads will also go to a similar process but to a bench flow. It's great that I will be getting so much data out of this build and from such a reputable guys as Zcar and Rebello.
That is it for now, I'll try to keep this thread up to date even though I won't be in the US, but Zcar and Rebello assured me that everything will be well documented and I will receive occasional updates on it.
4.15L NA VQ Engine Build with Rebello and Zcargarge
. Glad everything is working out for you. That's awesome Gabe!! Keep up to good work. I certainly hope Rebello and ZCG can reach your goals...you car will be very fast.

)........300whp isn't easy.
