We encourage you to email us to discuss your build. Pricing is based on the number of revisions your tune will need, the size of turbo installed, the number of modifications, and your power goals.

From GTRS eliminator kits to complex builds, we support just about any turbo.

Injectors must come from a reputable source. Injectors larger than 1000cc are supported, but must come from one of three modifiers. May include 3bar MAP sensor, larger MAF housings, blow through MAFs, ProMAF. Rods and/or upgraded valvetrains may be required depending on power goals. Big port head supported and suggested for higher horsepower goals. Cams, displacement/compression changes, upgraded or aftermarket throttle bodies are supported. Water methanol and ethanol supported. 3bar MAP pressure requires rods. E85 use with most turbos requires rods.

The narrowband ECU found on model year 2000 in North America has some limitations. The ECU lacks the resolution to handle injectors larger than 550cc well, effectively limiting you to a GT28 series turbo. Wideband conversion is possible and the real time fuel correction provided by a wideband primary O2 sensor is much safer for your investment. We offer wideband conversion kits if needed. Upgraded MAP sensors are not supported on narrowband vehicles.

After submitting a quote, we’ll be in touch with pricing and/or suggestions.
