Upgrade Sequencing — Stage 2
Take your car to as much as 400hp - and click off high 11's in the 1/4 mile!
- Intercooler Pipe Upgrade
The Buschur Racing Upper I/C pipe replaces the stock rubber and metal piping setup with a mandrel-bent, polished stainless steel pipe. The stock Throttle Body elbow is replaced with a larger, better-flowing elbow as well.
Typical gains are 7-10 hp with this part. Kit includes all hose connectors, and will not blow off.
- Extrude Honed Intake Manifold
The Extrude Hone process will smooth the inside of your intake manifold to allow better flow. Typical gains are about 20 hp - or as much as .2 seconds in the 1/4 mile.
- HKS Vein Pressure Converter (VPC)
The VPC is a fuel computer system that replaces the factory Mass Airflow Sensor (MAS) setup with a Manifold Absolute Pressure (MAP) assembly and controller. The benefit of this conversion is that the flow of the intake system is improved by eliminating the restrictive factory MAS sensor assembly.
This modification allows the blow-off valve to be vented to the atmosphere for better performance and sound, as well as allows the use of a much larger, better flowing air filter assembly and larger injectors (if using larger injectors, request the custom Buschur Racing PROM for larger than stock injectors).
When mated with the HKS GCC, fuel trims are adjustable throughout the entire RPM range.
The VPC is used on ALL of Buschur Racing's cars, and with a replacable PROM can be used on everything from stock-appearing cars to strip-only monsters!
When compared with less-sophisticated A/F controllers, the VPC requires much LESS tuning - and can better deal with a wide variety of driving conditions, while providing a much higher level of performance potential.
- Upgraded Turbo
Buschur Racing offers a wide range of turbos - from stock-appearing 16g's to track-bound Garrett T3/T4 giants, in your choice of porting and/or clipping.
We also carry the full line of Frankenstein turbos. Call for assistance in selecting a turbo that will allow you to reach your performance goals! Buschur Racing has many years of experience using a wide variety of turbos, and will only sell what we know will work for your DSM! Larger turbos require the use of larger injectors, bigger exhaust, a fuel computer like the VPC, and an external wastegate for best performance, so keep this in mind as you make your turbo decision.
- External Wastegate
By installing an external wastegate, excessive boost will be dumped to the atmosphere (or back into the exhaust system if you have your car plumbed that way). This modification will eliminate boost creep with any size exhaust even with the largest turbo we sell.
An external wastegate provides faster spoolup, and better performance in the upper RPM range. HKS makes the highest performance wastegate on the market, and Buschur Racing orginates and manufactures the proper mount.
- Fuel Injector Upgrade
Depending upon the larger turbo choice you made above, larger injectors may be needed, as well as an external wastegate (all turbos larger than 16g). If you have a VPC, you'll need the custom Buschur Racing PROM. Fuel control of some kind is required when installing larger injectors.
- Cozmo Fuel Pump
If you install a 20g or larger turbo, you'll also need to upgrade the fuel pump to provide enough fuel to prevent running lean at boost levels greater than 18psi. We recommend the Cozmo fuel pump for this purpose.
- SX Adjustable Fuel Pressure Regulator (FPR) and custom mount
A very high volume fuel pump will pump more fuel at idle than the stock fuel pressure regulator can bypass to the fuel tank which will increase the fuel pressure so much that idle will really suffer. We recommend the SX Adjustable FPR to solve this issue, and provide a custom mount for your stock fuel rail to make it fit.
- Front Mount Intercooler
For 1G cars, the Buschur Racing intercooler is the best performing setup on the market! It uses a very large, high performance core with extremely short piping that has very little impact on the cooling ability of your radiator.
Factory power steering and Air Conditioning can be maintained with our kit, and the intake charge is cooled much more than with our competitors Front Mount kits with a lower pressure drop.
We also sell huge track-only intercoolers for 1Gs and Conquests, and can custom-design an intercooler for use in any 4G63 powered outlaw racer.
Our kit comes complete with a new overflow bottle, all hose couplings, T-Bar clamps, and beautifully polished stainless piping - low profile fans are also available.
- Weight Savings (that won't kill you)
Remove the padding from the bottom of the carpet.
Remove the tar-like sound deadener on the floor of the interior and on the firewall.
Get rid of the spare tire, jack, tools, rear seats, rear deck lid, rear hatch carpet, metal brackets in the rear hatch, and the heat shields in the driveshaft tunnel.
Convert from power steering to a manual rack.
Get lighter wheels and tires.
- Weight Savings (that might kill you - for track use only)
Remove the rear bumper.
Cut weight out of the front bumper and have an aluminum bumper bracket made to support the bumper cover.
Remove all seat belts and the front belt motors and replace them with 5-pt racing harnesses.
If you install all the Stage 2 parts, with tuning, your car will be nearing (or exceeding) the 400hp mark! A well-tuned car can see ET's as quick as 11.40's at approximately 121mph with these modifications. Want to reach the 10's? Our Stage 3 components will help get you there!
