Would anyone need this? It's useless to us (it arrived 16 months after needing it). We would let it go for $45 (new in the box). This cost $120+ new.

It's a replacement engine mount from Innovative Mounts. It fits the vehicles listed on the front of the box.

1994 Honda Accord.
JDM H22 engine swap.

The Red dyno graph, the vehicle was using a chipped ECU. The chipped ECU was tuned with Honda Tuning Suite software (in the past).

The Blue dyno graph was done after tuning on Hondata s300.

2000 Honda Civic Si (a clean one).
It has a stock b16a2 engine with a Vortech supercharger installed.

Just a few pulls into our dyno session we found the cylinder head gasket was bad. The coolant system is pushing coolant when the engine is under boost. This stopped the tuning session.

That supercharger was sounding good 🤘

So far the car made 266 wheel horsepower and 182 wheel torque.

Suzuki Samirai.
K24a swapped and turbocharged.
Tuned on 93 & Fueltech ft550.

We had a fun time working out all of the bugs on this new build. I think we encountered all of the problems. We got through them though 😁.

The customer used a factory Toyota 4 Runner transmission and clutch. Because of this the setup is limited to low 300's for wheel horsepower (so the clutch doesn't slip). Once the customer gets a good clutch we can turn it up.

On wastegate pressure (6 psi) the setup made 332 wheel horsepower and 248 wheel torque. This thing runs so much better than when it arrived.

2015 Honda Civic Si. K24A turbocharged.

It was probably just purchased from auction. Currently owned by a car lot. It came to us not running. It had a 4 bar MAP sensor and some 1000cc injectors being utilized with a factory engine computer and no tuning solution. We resolved that with a new Hondata Flashpro.

We also address an over boost issue, as well as some battery wiring problems.

I'm uncertain of the turbo kit used. On 6.5 ~ 7.5 psi the setup made 303 wheel horsepower and 256 wheel torque.
