But what about the higher-compression head? It would make more power, right? I know people put GX160 heads on 212-clone engines because of the higher compression.

That is a jdm-drift-boi myth, they have the same compression ratio.
Realistically compression is also determined by your choice of pistons and headgasket so you are flexible no matter which path you use.

Woops, been spending a little too much time on the small engine forums. My bad.
So there's practically no difference between a 1.5 and a 2?

The 2jzge and gte heads flows better. But I have yet to see a flow test involving the head and intake manifolds though as the 1jz has short runners and 2jzs have long runners

yeah, basically the 1J head is great for 2.5L and an easy way to increase top end flow (beyond a ported 1J head even) is to install a 2J head (Driftmotion just did this; coined 1.2J). Putting a 1J head on a 2J bottom end is simply to save costs when you already have all the mods/built head and don't want to start over. It's just to save money; that's why the Japanese did it and that's why I was thinking of doing it before sticking to 1J bottom end. The best way to do this is to port the 1J head to flow as close to the 2J head as possible, but given the money aspect many just toss them on and deal with less flow.

read back a few pages; it was started as a way to reply to a separate OT clause within the original few posts, but then we all ended up just flying off OT lol

Apologies, idk what that was. Anyways, someone tell Toyota to mod out 2j's for a better more linear dyno graph, ya know, all the torque curves whatnot, shave off 20000000kg's off it, make it rev higher, make it more durable and more reliable, DO NOT PLASTIC COVER IT the way everyone does it these days, call it 3j. Oh, while we at it, also tell Toyota to make like a special limited edition Supra/SS w that 3j. Put to of em in one crank, qt it, hell, make 1800hp while at it, let everyone shut their mouths. Call the engine eXperimental JZ (xjz) or smthn.

Hey, the 3JZ-GTE was my idea.
Bet the dealers trying to sell you this car over a GT86 will have only 5 arguments:
  1. It's a Supra
  2. That engine is "the spiritual successor of the legendary 2JZ"
  3. Every part of the car is "race-car inspired" and has "race-bred dynamics"
  4. Much more luxurious, and is "the cruiser to the GT86's boy-racer feel"
  5. It's a Supra

Looky looky, it's the new supra.

So aggressive, not even the mustangs and chargers would want to race with you and give the old corvette driving owners a run for their money.

The horsepower? Pssh, don't worry about such a trivial thing, imagine this puppy screaming when step your foot on the gas. It's both a DD and a weekend cruiser. All while holstering an arm around you to persuade you with half truths.

The engine can be modded to be 1000 HP even though the engine hasn't even hit aftermarket yet. It's a 3JZ bro, no shit they're going to find ways to be like the MKIV.

I'm imagining the multiple angles and pitches and I'm going to be shaking my head.

Fact check: this car would get its rear diffuser kicked by any Camaro SS, Stang GT, or Dodge SRT8. Even a C5 Vette would beat it in a stock-for-stock drag race.
BUT 3JZ, BRO! SUPRA AMIRITE!
But I will say, they don't need a single pitch to get me to buy it.
If I could afford it.
