Ok, lets say I'm building a motor for a open wheel car (think F1) and build it to 2013 spec (1.5L forced induction and about 10,000 other regs). Lets also say that everything is made with titanium and other high strength materials. How high will the motor rev? Bonus question, how much horse power will it theoretically have?


Money is no issue, just looking at feasibility and good educated guesses on this before I consider blowing enough money on a motor to buy a nice house.

Issue isnt really getting the motor to rev, its getting the trans to shift that high.

Also, no one has destroked a 4g63 that much, at least not that I have seen in the last decade so its new territory. I doubt you'll get much usable info other than hearsay and guessing.

Look at any 4 cylinder Suzuki, Honda, Kawasaki, Yamaha bike engine. Lots of technology in there and they rev well over 10K.

the transmission will not be a typical transmission. the transmission I'm looking to source can handle up to 800hp, so getting power through that shouldn't be the issue. It's also sequential, and costs a hefty amount on it's own. So far the motor is down to a Renault, Honda, or a Cosworth. I'd just like to see if destroking a 4G63 would work. Just for ****s and giggles really. I'm leaning towards a cosworth or a renault right now.

Mitsubishi had the Mitsubihi Mirage with a 1.6 4G63 engine already back in 89-90 but no where close to the 10000 rpms.

When you are talking about that kind of set-up you are going to be much better off going with something that is proven to perform in that setting. Let someone else foot the R&D costs. It will cost you a fortune and give you a ton of headaches trying to make a one off set up like that. Plus if you are racing it, replacing parts will be just as expensive....

the jdm colt has a 1.5L turbo motor i believe

look into and research 1300cc motorcycle engine and tranny and send that motor into ams those guys can do anything

4g61 crank, 4g64 block, titanium valve train, dry sump, dog box, a bunch more stuff


assuming the crank could oil properly at these speeds...

1.8l going to 12k-13k all day with a 67mm...

probably 700+whp from 7k up no problem


Now u build me this motor cause I answered the bonus question?

I had a friend that had a 1.8 mivec lancer 1.8 non turbo tho.
It for somereason had an aftermarket computer and would redline at 11000.
It was slow as **** but reved way more then a honda so he thought it was cool.

Im sure it wont help you but its worth a
