Completely different.
Notice how the injectors are way up high. And they're aimed at the intake valves.

This is a DTM Alfa Romeo 155 from the '90s. 420bhp @ 11,500rpms.[This message has been edited by La fiera (edited 06-24-2021).]

It may be worth keeping in mind engines like that don't need to idle well or pass emissions or be terribly reliable or be tractable at low speeds. None of these are obstacles to pursuing your vision, I just think it's important to remember that things that work well on race cars don't always translate to street cars. I've got a friend who's a well-known E30 M3 enthusiast and he'll be happy to tell you why his personal '88 M3 is mostly as it came from the factory and not similar to the DTM cars. 9000rpm is intoxicating but 2000rpm is pretty important for getting to work. 
I would probably be looking more towards things like ITRs than AR DTMs.  [This message has been edited by thesameguy (edited 06-24-2021).]

Absolutely! That's why my Fiero is a dedicated race car, not a daily driver.

Word. Then who the eff cares? 
IMO, this is the best way to approach it. Having to build one size fits all stuff is stressful.

My previous Northstar would accelerate uphill from 1000 RPM in 5th gear.

Now that I walk 3100 feet to work, I can think of having a totally impractical car! [This message has been edited by pmbrunelle (edited 06-26-2021).]

Rotating assembly is finally balanced! Due to the lightweight of the pistons, rings and rods the crankshaft had to be lightened 40g!
Next, the heads. The porting part is done, just waiting to finish the fitting of the new valves!
