While in the autocross stage Carlos was bitten by the modification bug. Strut tower bars and a better flowing exhaust. Then an AEBS header for his SR20DE gave him the first taste of power. A few strategically placed NISMO stickers did the rest! Of course, adding some JWT S4 cams really brought the car to life. To facilitate shifting, a B&M shifter was installed. Carlos first serious attempts at drag racing were with an SR20DET U13 version with a T25 turbo installed in the engine bay. It ran out of breath at 7000 RPM. Staying with the same engine, the S4 cams were installed along with a GTi-R turbo. This combination produced 316 whp at 14 lbs. Next was a GT3071R that gave 350 WHP at 16 pounds. I laughed when Carlos commented that this was 'enjoyable'! The man is obviously hungry for power because next up was 28 lbs of boost and unknown horsepower. Crazy horsepower that produced too much wheelspin on the dyno to get any numbers – but at the track he got a 12.0 at 123 mph. However, no matter how many parts he added to the car after ordering from Greg at GSpec.com, he couldn't break into the 11s. That U13 was running 750cc injectors and was on all stock internals. He went through a few head gaskets – due to the high boost pressure – during this phase.
After pushing the U13 engine to the limit, Carlos was ready to start working on the SR20VE that had been stored in a corner of his shop. Working with renowned SR20 engine builder Mazworx, Carlos now has a sleeved 2.2 litre block and a head that has been ported, polished, with upgraded/oversized valves and upgraded springs. Knowing that the VE engine would not stay naturally aspirated, Pauter rods and 90mm CP pistons were installed. The crank was knife edged and balanced at AES Automotive. AES built the exhaust manifold, the exhaust, and a ton of other components on this car. Vibrant Performance parts are used exclusively on the exhaust piping, intercooler piping, and intake.
