Comments Off on Are You Ready For Wednesday Night Drags 6/26?
We have been taking care of Carlton’s 350z for a long time and he recently needed to replace worn brakes. Instead of the costlier OEM rotors/pads/lines we installed a Stoptech Sport Kit:
The kit consists of slotted rotors, stainless braided brake lines and performance pads. This is a fantastic alternative to the OEM parts and perfect for the demanding Z-car owner who enjoys”spirited” driving. If your Z is up for a brake service and you don’t want to spring for a full aftermarket caliper big-brake kit, consider the Stoptech Sport Kit!
Gary M came to ZCG to have Stillen intakes installed and an UPREV tune to maximize the benefits of the new breathing mods. His G37 Convertible already had a custom exhaust installed so here is the baseline with mild gains from the Stillen Gen3 intakes alone for a total of 294hp/244tq to the wheels:
Rob’s UPREV tuning yielded +8hp/9tq to the wheels for a total of 304hp/253tq. On the dyno note the improvements from low rpm all the way to redline:
Just another example of how UPREV tuning can optimize your bolt-on power mods!
Part 2 in a series: ZCG also supports vintage cars of non-JDM origin!
Tuning The Datsun 510’s Rival
Alfas and BMWs have long been rivals of Datsun 510s. Fighting against both BMW and Alfa for the 1971 Trans Am 2.5 Challenge, a certain red, white and blue liveried BRE 510 coupe took the championship that year and in ’72/’73. So, at the shop it’s no secret we LOVE 510s and know for a fact that they are much cooler than their Euro counterparts 🙂 Tom H. is a gearhead and ran a 280zx in the 24hrs of LeMons last year with some help from Z Car Garage. Tom recently came to the shop to help tune his beautiful, modified BMW 2002 and we readily accepted the challenge.
The 2002 is a 1973 non-Tii “roundie” in Sahara paint with very subtle exterior mods for a clean, pre-’72 Euro look: shorter chrome bumpers, no lower trim on the doors, deleted side marker lights and basic BMW steelies. A great stance and handling comes from Ground Control coil-overs up front and Ireland Engineering Stage II springs in the rear with Koni shocks all around. Tom turned the ’02 into a total sleeper by modifying the motor with a ported head, custom 9:5:1 CR pistons and Megasquirt EFI. He recently converted to TWM 45mm throttle bodies which complicated tuning so ZCG came to the rescue!
On the dyno, baseline numbers were 98hp/129tq to the wheels. Great plateau of torque available from low rpm but still in need of tuning and full rev range:
After Rob’s tuning the mighty ’02 made 131hp/139tq to the wheels! Here is a short clip of the Bimmer on the dyno:
Just for kicks we even weighed the BMW to see how it compares to a Datsun 510: 2297lbs vs 2160 for Rob’s SR20DET-powered dime.
We enjoyed working with Tom and his very pretty(and potent!) 2002. Enjoy the Ride Tom!
