Bolt on turbo kit (7 Viewers)

Does the turbo require using Mid- or Premium- grade gas? Or do we get to stick with Regular-grade?

You don't want to know how much gas costs in Canada but it was CDN $1.56 / litre yesterday for Regular-grade gas - that converts to USD $4.43 / gallon.

I don't want to put words in Joey's mouth but i'd say yes, premium (91+ octane depending on elevation) would be required in any boosted application.
Scott mentioned at one point getting away with a tank of regular as long as you stay out of boost. I've had to do it in a 21psi boosted subaru before as well. Just stay out of boost.
If you're boosting, you need high(er) octane fuel to prevent detonation/knocking, even at 5-6psi.

Damn those are California prices

And yes premium

for force induction, i would put premium grade gas, the more octane, the better. Low ignition temperature fuel is key to prevent pre detonation.

 

[richmondbob]

BTW that was for Regular gas.

Premium gas was CDN $1.71 / litre = USD $4.84 / gallon

There has been a lot of talk about that but honestly I don’t think you’ll have a problem. If anything, the result of tonight will be a life lesson for me

Tonight

hot compressed IAT + gas =
I hope people don't cheap out on gas w/ FI setup.

Actually, octane is a "resistance to burn" in order to better control the flame front within the engine due to the heat of compression. "Low ignition temperature fuel" would actually refer to a LOWER octane, as it takes less heat of compression to ignite it.

The best way is to have the spark plug ignite the fuel rather than the heat of compression. High compression engines must use higher octane fuels so the fuel does not ignite too early before TDC.

So, while our Landcruisers are spec'd for Regular (87) grade gas, the addition of the Turbo requires moving up to Premium grade gas?

I've put driving pleasure above mileage to date, the increased cost per week can't be ignored. Just trying to understand this as I'm running my numbers before pulling the trigger tonight.


CDN to USD is already hard on the wallet plus having to throw in an engine top-end refresh (and possible bottom end if required) to avoid future issues is adding up fast. My engine is running fine so unless there's no recommendation to refresh the engine?

You asked and everyone answered. Yes higher octane fuel. The point is to avoid detonation with the additional pressure inside the cylinders.

Look at any line of cars that offer NA and turbo options. The NA will most likely be able to run on basic grade fuel. All the turbod will require premium.
It's not a just in case thing, it's physics.

 

[richmondbob]

@Wompom yup, I did ask and thanks everyone for the answers. Had a turbo'd car before that required Premium but was hoping that wouldn't be required on the LC. Time to re-crunch the numbers.

If I hadn't just spent 12K in HVAC/plumbing repairs, 10K on a Newbaru, and 8K in "tax cuts", I'd be seriously on board. I'll have to wait a year. I might be able to play with the Newbaru though...

Yeah only so much I can do

Damn, that's Oz prices right there!
