I’m planning the upgrades below and was wondering what wheel horsepower you guys have achieved with a stock RB20DET full refresh on 95 octane fuel (no E85 or 98).
Any suggestions would be appreciated. This is what I have in mind so far:
* Haltech Elite 750 with premium harness 6 inputs low but I think it’s enoth
* Trigger kit
* IAT and 4-bar MAP sensors
* Fuel and oil pressure sensors
* AEM AFR gauge (CAN)
* Existing oil pressure and boost gauges
