2ZZ starts at over 8 stock, right?

That'll be good for a bit.

So the other day I had to demonstrate to my students (I'm a TA) how to conduct a proper dissection of a rat. in the past i was always told by teachers and friends that i was borderline psychopathic because i thought it was fun to do dissections despite me saying that its because I'm fascinated by the structures inside of them. Today I believe i was one-uped because a girl who is in my tutorial sent me a video of her using what I taught to perform a vivisection on a rat she found. I emailed her back saying that what she did was essentially torture to a living animal and that I am supposed to report that type of behaviour to the prof. which could result in a variety of academic and possibly criminal punishment. She replied with "I lived in the house your family lives in."


Well guys, this may be my last post.

OMFG. Don't tell her what you're supposed to do. Forward that shit to the faculty and let them decide what to do with it.

Too late now...

On a different note, I saw a box of condoms that said "chocking hazard to minors"

WTF

DO THEY THINK WE'RE ARE ALL PEDOS OR SOMETHING?

8.25 with the Celica ECU, supposed to be good to 8.5, but there are some reliability problems at high rpm.

There was a 15k build that DDPR did and their 2ZZ made 250hp @ 9000rpm with a 10k limiter (catless though), but it didn't have any titanium bits. I think with custom titanium rods and valves + Cosworth forged pistons (you can get rid of over 30% of the reciprocating mass like this) you could have a reliable high rpm machine.

One problem with the Spyder is that the stock tach doesn't go past 8000 and I can't get over how weird aftermarket tachs look on the car. Thus I'm thinking maybe just sink 2k into the head and engine management for a 7700rpm limiter with peak power at 7100 might be good enough. With a 6 speed transmission swap that would come out to 3k total vs. a bit under 5k for a 2ZZ swap. With a header, I think that setup would be making a bit over 170hp which is pretty close to a 2ZZ and plenty fast. The 1ZZ is also 10kg lighter than the 2ZZ, which is worth 2 of those horses heh.

Yeah, but you're pretty much stuck if the mod bug bites again. Not to mention stock reliability of the 2ZZ. Plus you get your precious California catalyst.

I think the differences between Toyota F and G designations is more than just the head. I think the rods are beefier, too. Not 100% sure if that's correct or, if it is, is still the case in the ZZ, though.

Edit: how similar are the instrument clusters? Failing that you could do an AiM dash. Because racecar.

Well, the idea is to have 170hp to play with instead of 140hp while I wait for either a new MR2 to come out (unlikely) or enough mod bug and money so that I go all out on a 2ZZ build. Why have variable lift when you're only revving to 8250 The rods are weaker but the 1ZZ is supposed to be able to run at 7300rpm and there should be some extra margin of safety left.

BTW I don't think the 2ZZ has a precat, it runs rich with a smog pump to heat the main cat. That's one of the main reasons it makes way more power. The headers on the 1ZZ are like 5 inches long, aka garbage.

I'm suggesting there would still be a choking hazard even without the condoms.

haha imagine a condom company being sued because a kid chocked to death on it.

Intake: 292° duration 11.2mm lift
Exhaust: 276° duration 10mm lift

High cam profile probably has a bit more to do with it than just the header.

It does, but by the time you do all the work to get the 1ZZ over its rev limit, you have a very capable EMS (tune = moar power) and a fat cam (not as good as the 2ZZ but decent).

But a Greddy EMU or Apexi PFC are really expensive and need a wideband for tuning so maybe this is a stupid idea afterall :/ A 2ZZ with factory ECU will be more powerful with less work and you can trick it into running at a better AFR with a 200 dollar narrowband emulator.

having to deal with physics and calculus 2 at the same time while being depressed...this is fun.

Keep your head up!

Wait what are you doing in those classes as a senior?

Senior? Lol no im fairly behind in my credits, i dont have any electives left so its just math and physics and some computer science classes until i transfer.
