VTEC YO!The goblin was designed to use as much as possible from a donor car. You can forge this path but you will do it alone with no one else to rely on having done any engineering for you. Seems like a ton of risk for what? What is the upside to using the honda motor over the ecotec?
This is the route I am going with my Goblin.Could go old school on the lights and skip the modern body computer module.
Out of curiosity, where exactly is the trigger wheel on these? On my DSM I switched over from the CAS (Cam Angle Sensor) that sends signals to the ECU for cam and (predicted) crank position to adding a dedicated trigger wheel on the crank. The previous tooth count was 2 cam, 4 crank, now it's 1 cam and 12 crank. Of course I have an AEM standalone making this possible. What I'm getting at... is there a way to change your trigger wheel?I am going to be running an older Ecotec from a Cavalier and the Cobalt PCM/ECU will not run it do to a different trigger wheel on the crankshaft.
A lot of k20’s can be built into monsters of a motor and be fairly stock, that’s one reason I wanted to try it outThis is the mods from GM for the Ecotec to get it up to 1400 HP

You can get over 500 HP with an LSJ turbo swap from ZZP.

The Honda is a very cool option but to get to over 400 hp to the tires, it may not be the most economical choice.
I haven't researched Honda upgrades at all but I am very interested in seeing one used with our Goblin.
Our Goblin with a 200 lb driver has 1100lbs on the rear, 600 on the front.Horsepower is all good. But, at some point, you become traction limited. A 1,600 lb Goblin with approximately 60R/40F weight distribution gives about 960 lb. down force on the rear axle. Not a lot of weight to try to get huge horsepower to the ground.
I know traction will be a big problem if I do get to very high horsepower but I would be happy with 500-600 my current setup is 500 in a 2800lb car and it runs high tens so I can’t imagine 600 at 1800lbsOur Goblin with a 200 lb driver has 1100lbs on the rear, 600 on the front.
To obtain the same power to weight ratio you currently have, you only need approx. 285hp in the Goblin. Which is easily achievable and beyond with an Ecotec. Then you dont have to redesign the back half of the car. Unless thats what you want to do, 'cause that's half the fun.I know traction will be a big problem if I do get to very high horsepower but I would be happy with 500-600 my current setup is 500 in a 2800lb car and it runs high tens so I can’t imagine 600 at 1800lbs
