1st Gen Lunchtable Thread - General Discussion

If anyone needs to work on their grammar, it’s definitely you.

 

It's a bit less of a restriction when there's two of them and they're M112 or twin screw

 

Or

 

That guys actually an interesting dude. Ozzies make some neat stuff

 

the size of the hole in the m62 blower would likely be good for 500-600. have to remember the blower will still be letting air through too

 

Idek how that works. How do they transfer the power from each engine into one transmission?

 

you're and asshole.

 

gears... its not hard. the engines have to be synced though. one making more power than the other or a major rpm difference would be bad

 

I don't think I'd bother unless I was staying near 400hp. Any more than that and it's just going to be a heat pump. That bypass is going to be too small and the rotors will pass some but anything that passes through them even if there isn't compression happening is still going to be subject to latent heat transfer. Plus you have to rig a system to switch the bypass open at the right time and tune for the instant difference in pressure and flow at the crossover which is going to be a dynamic problem with each gear. An M90 would be big enough for 550 or so. But again why bother when compound turbos are easier to configure and package.

 

hmm. your not on the same level of weirdness as me. damn.,


im doing compound. just because. if i can get 600 im happy.



hmm maybe i can do a KERS system

 

Sick burn dan

 

I'm happy to talk about it, it's a cool idea, but entirely impractical. It would cost more and do less and likely do it all not that well. If you're gonna twin charge it's better to just spin the blower slower and blow through it and be happy making the 380-420hp it's going to be worth. Anything above that will be deminshing returns and bring your knock threshold even closer. There was a car that actually did everything you're talking about from the factory, it was the Nissan March Super Turbo. It worked and it helped spool it's rather large turbo and then let the turbo take over at about 3k RPM. But the SC wasn't an intake integral part so they could actually put a robust 2.2" intake switching valve in that way the turbo didn't have to bother going through the SC at all. To date it's been the only factory twin charged vehicle, cause turbos are much more efficient nowadays and the SC isn't worth it.

 

Also an option, if it's between build a 5VZ for boost and swap in something else for boost. I'd probably choose the something else route. There are other Toyota engines that take boost better. But I understand wanting to stay brand loyal and let's face it LS swaps are so common it's downright boring. It's not even a challenge to reach 500+ hp with one and a single turbo.

 

Challenge is what I like. I seriously considered a 2jz swap. But the 5vz has bones for power. Just costs a lot to extract

 

We were earlier. I'm talking hypothetically if I were to get the urge to boost a 1st gen or 3rd gen runner. The 2 and 3RZ engines are the best boost candidates. The 5VZ can have potential too but it would cost a lot more to build because there's a lack of support for it. Somewhere along the lines, the aftermarket decided it didn't have enough strength, flow potential, something.... despite being the more common engine choice in two extremely popular vehicles. Meanwhile speed parts for the 2 and 3RZ arent that hard to come by, with exception of the SC (which isn't what people who are building for high power even consider anyway).

 

The 5vzs biggest issue is it is too big to swap into a lot of cars and heavy. The Rz series has way more potential in swaps

 

Time will tell how my build goes. The bottom end built looks like it should handle power over 1000 easy. But I don’t see any record of that so who knows. Will I push that far? Maybe. But at that point it likely won’t be in the taco.

 

I get wanting challenge. But the challenge here isn't really boosting technology, it's having a big enough wallet for custom internals since the platform has no support. The boosting technology already exists, aftermarket ECU, fueling upgrades, a mild port and polish, and a single turbo would get you past your goal easy enough but the poor beast wouldnt be able to hold on to its internals.

 

The Camry crank will likely be my
Limiting factor in the build. But it is a forged oem crank. They’ve proven themselves in other Toyota engines for being stout. The pauter rods should be more than enough for excessive boost. And pistons. Well they’re forged. What’s more to say? Head stud size and quantity make me believe head lift shouldn’t be a worry. Head flow is going to be tested.. cams are the big question right now.

 

Really wish I could get my
Hands on those trd heads someone on here had listed for sale... that would be the best.
