Calibra C20XE 350hp+ on Ethanol
This is one of my preferred cars that I use for trips and some TrackDays. It is almost stock and will start upgrading for 350hp+
I've just finished internal engine upgrades and will install VEMS on it.
This car has a cam sync and I will try to use every already deployed sensors (not sure about MAF yet).
Engine upgrade
- Engine code: C20XE
- Forged pistons (Mahle)
- Stage I head modifications
- enlarged and polished intake and exhaust runners
- reshaped valve guide bosses
- 9.5:1 compression ratio (down 1.0 for turbocharge)
- Oil cooler: B&M
- TurboCharger
- Not decided yet. Probably a Garrett ballbearing GT2860, not decided on A/R too. Have been thinking about a Lysholm compressor too.
- Custom exhaust manifold
- Custom Intercooler
- 3" aluminum intake
- 4" Downpipe
- Ignition
- standard coils (Wasted Spark setup)
