The Need For More Speed ... ?

My little ported 1.7 will probably run 9.90s at sea level, but I nevertheless find myself giving sincere consideration to upgrading to this one ...

You probably should've started with a 2650 instead of investing so much time/money on the 1.7.

I see this argument a lot and it makes no sense. Supporting mods for the 1.7L also apply to the 2650. Money spent on supporting mods do not get subtracted from the cost of the 2650. It’s $2k for 1.7L porting vs $7k for 2650. And the ported 1.7L can be sold for $2k. It does not equal money wasted. There is value in the enjoyment of running the ported 1.7L for however long one enjoys it.

I looked at it as a challenge, and it wouldn't be difficult to sell. Not saying I'm going to do the 2650, but it is appealing.

Well it's also the fact that the more boost you put on the 1.7, the more heat and wear you put on it vs the 2650 producing the same power but with less heat and wear.

Plus the 1.7 won't make as much power as the 2650 right?

It just depends on the person and what their power goal is.

That 7k also give you tons more room than the little 1.7. It's also more efficient and doesn't require any extra cooling mods to keep the heat soak down. If you're chasing power/times that the op is go with the bigger blower.

I get it I've just been the type that prefers to overbuild that way I'm not going back and re-buying anything.

The thing is you can sell a stock 1.7 blower for 2k also. You're basically throwing away money the more you invest in the 1.7 if you even think you might go with the 2650 later.

I've been offered $3500 for mine, so I look at the base cost as ~$8000 - 3500.

Then you should take it ASAP because no one I've seen if offering that for a ported 1.7L.

I agree, which is why I did a custom valve train first.

Agreed and will add. If one has no intention of ever racing their car like myself, the power on my new build for the street is more than all I will ever need or want. Each owner here has different ideas on how they use their car, so not everyone will ever agree. My last built new car will be just what I always wanted.

Ok, so if I spent $2k modding my 1.7L and I sell it for $2k where did I throw away money? It’ll actually bring more than $2k Kong X ported. Plus I enjoyed running it for x amount of time.

Which is fair for you but op does race his so him going for a bigger blower makes sense. So the 2k spent on porting the blower along with interchiller if he has one could've been spent on the 2650.
