GC Stock-350WHP
GC+ Stock-400WHP
Ready to take your 10th Gen to the next level? Don’t want to deal with core charges, long lead times, or restrictive factory housings? Look no further! VTT has you covered with our 100% new casting “GC” turbocharger upgrade. We start by keeping the great design elements of the factory 1.5L turbo and removing the not-so-great ones such as the small factory inlet area, bearing housing oil structure, thrust bearing, and anything else we saw that could be improved upon. With the basics covered, we stepped it up a level by adding proprietary VTT changes and finished off by having all these parts cast to OE quality. What this means for you is serious 1.5L power made easy; GCs are a drop in turbocharger upgrade that supports up to 400WHP while maintaining near factory spool and all factory connections including oil, water, downpipe, and charge pipe.
Add a Phearable OTS Tune
We worked with them exclusively on a tune for the GC+ and they are proud to offer an off-the-shelf tune as a package with our GC+ turbo.

Get this turbo you won’t regret it. Installed on my 2019 Civic SI and had the car dyno tuned at Innovative Motorworks and the car made 304whp/314wtq with some of the smoothest curves on 93 pump gas. Beautiful turbo and great customer service. Truly drop in fitment and factory connections.

The best mod you can do on ur 10th gen. I bought the gc+ for my si pair with the ots tune from phearable and it’s phenomenal. I’m verry suprising about the fuel trim and knock control. I have the turbo install and the knock is staying at 0.49 since on 94 octane. The map 3 it’s insane it remember me some old vtec. The top end with this turbo is crazy. This tune looks like more gentle on the motor at low rpm and you can’t feel any difference on turbo lag vs the stock turbo.
