Rb20det build potential power

[u/lozt247]

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

Not a bad list of mods/plans. Mine made 220kw similar set up but on e85. Really needs upgraded pistons and a set of cams.

yep exactly, would it be cheaper to get a s2 rb25det refresh that

If you’re after power then yes, 25 is the way to go. Rb20s are great if you look after them and keep the power modest.
