This has been a fun project to say the least. After years and years of playing the transmission game with with custom parts, breaking cases, long lead times etc. It was finally time to make a change. Something that I can easily get parts for. Here you have the first ever k series trans attached to an MZR engine. Thank you James Emmino for building this bad ass unit of a trans with a billet bell housing. I got to play around with my machining back round to make it all work, building adapter plates, mounts, intermediate shaft adapters etc. We successfully made it through a day of testing on it with low power. Gave it all a once over and all systems are a go. Cant wait to get back on the track and actually give the car some power so she hauls ass.

Tial 38mm EWG w/ 14psi spring

Another speed 3 bringing some heat today. These nex gen just make easy power. This is a 2.5 long block, precision 5662 turbo making 516hp/440tq on 93 and then adding in some ethanol we ended up at 691hp/563tq!

This was a fun one we did yesterday. Remote tune for .tuning in Canada, on speed 3. His car features a Bobspeedbuilt long block, g30-900 turbo and a dual fuel system running 94 octane in his stock tank and e90 in his fuel cell when in boost. Ended up at 739hp/610tq on the . Tuned with accessport!

Just want to give a huge shout out to . This has been 3 years since he did my cage so I was due for a recertification. As soon as tech opened my door they asked us if sua fab did the cage work. Needless to say I was in and out of there. If you need any chassis work. Hit that man up!

Tims GR Corolla in for a tune using software. This car came in with the infamous p2c90 code on a stock tune due to intake that was on the car. This code and pretty much any intake on these cars that will cause the code will make you lose power without a proper tune. Baseline on stock tune of 207hp/193 tq. Finished up at 304hp/337tq! Car sounds great and feels amazing. Message me for any of your GRC tuning needs!

Ethan’s 2024 GR Corolla came in for a dyno tune this week.

- GGP catless downpipe
- RK Ti track single-exit exhaust
- OTL MAF inlet w/ K&N airbox

I did a baseline pull on the stock tune file.
Baseline: 231whp/240wtq.

After some finessing of the tune with ecutek software we ended up at. 294whp/312wtq

Massive gains everywhere and in some areas of the tune were 80hp/tq

If you need your GR Corrolla tuned in person or remotely shoot me a message 💪

Come take a ride with me as the car is on the quickest pass it’s ever made, but unfortunately a failsafe shut her down at about 800ft and coasting to a 8.7@140 lol

8.58@178. Had to change my un**es after almost kissing the wall 👀.
