GT4 is the Clubsport (race) version of the GT4. It will reveal a ton for the street cars which will debut later this year... question is when.
Whoopsy had mentioned 4.0L but he had said it would be 4.0L for the streetcar. There are still rumors that the street car will have a different engine from the clubsport which means that Whoopsy would be right.

Just not based on the 3.8L in the clubsport.

On the GT4 thread, Chris3963 posted that the street version will have completely different engine. He is well connected; and, often right. So, will it be a 4.0 NA or turbo 4? The word "completely" has significance. Hopefully, it is NA 4.0. So, for the street version (ergo, Spyder), the speculation and anxiety are alive and well!

Chris had mentioned in an earlier post that it would be a 4.0L. I hope that's what he meant by "completely".
It would be a total letdown if they make it a turbo4.

IF i was betting it would be 3.8 for the GT4 Clubsport (we already know this now) 3.8 for the GT4 street and Spyder, and 4.0 for the GT4 RS.

When the street models are announced, we'll know why they chose not to use a single engine spec across the range (assuming there is a variation). I speculate it could be due to emissions regs. As is known, cost amortization (of R&D and build) is better with volume. Return on Investment (ROI) is better with a single spec. Since it now appears there is a possibility for the street models to have a different engine, I would bet it is likely to be a single version to be shared among all the variants, for the said reasons.

You can't sell an engine that burns 98 octane for the street in North America. Our gas is 10% corn and 93 is about the best you can get. Out west 91.

So we will get something less than some other places.

Full disclosure, I'm an European living in the US. There is very little difference between Euro and US fuels, we just use a different scale to rate them.
SP95 E10 (the most common fuel) is also 10% ethanol, whereas European premium SP98 is up to 5%.

Europe vs the States

In Europe, gas stations describe different types of gasoline based on their RON rating. It is typical to have 100, 99, 98, 97 or 95 RON with prices varying accordingly. In the States the descriptions look a lot like RON, but they are not.

Pump gas

In the United States gas stations describe the types of gasoline based on the Pump Octane Number (PON). That number is the average between RON and MON. This causes many problems.

If a fuel is 98 RON then it will be 93 PON -> 93 PUMP
If a fuel is 95 RON and 87 MON then it will be 91 PON -> 91 PUMP

Is American fuel quality bad after all?

No, not at all. Contrary to popular belief, fuel quality in the States is as good as anywhere else in Europe. Most Americans think that because they are running 91 octane fuel, their engine will blow up. It is the same as if they were using European 95oct fuel.

In our website you will find RON ratings required for each remap stage.
98/100 RON means you will need to use 93 PON in the States.

95 RON means you can use 91 PON in the States.

Everywhere else in the world, 98 RON and 95 RON gasoline usually are fit.Anything lower then that and your modern engine will have a lot of trouble adjusting, even on the stock calibration.

True. But, could they have made a version of 3.8+X51 that can take pump gas? After all, that spec was in production for 991.1 GTS. Making them to comply for current regs could be a different matter.

IMHO - If there is any difference in motors between the CS and the Street Version, I think it will be because of the Particulate Filters for Europe. IIRC, the Particulate Filters suck away Hp... We saw this for the 718T. They need to remedy that somehow and the reason they didn't for the CS is not to sacrifice weight for Hp... The 718 GT4/Spyder will weigh more than the ones they replace... Which is sad knowing that the Spyder first started off as an Ultra Lightweight concept. Oh well... Time will tell.
