crazy280 Posted September 5, 2004 Share Posted September 5, 2004 Chris240turbo My point was that it is DIFFICULT to get that much power from a 2jz-gte. "BUILT" means rods, pistons, rings, bolts, cams, etc, etc. NOT just bolt-ons. Sorry if I was unclear. And I think the guys at SCC are pretty cool when it comes to having their sh!t together. Who knows, they might be journalistic leaches, I don't know for sure. At least they always have great technical writeups and explanations for how things work. Even I can understand how a helical LSD works thanks to them! Anyhow, I gotta give you credit for that great advice you gave about street racing. It is dangerous and young people need to understand that. Maybe they won't listen to an "old guy" like you, but they should. Obviously you have some sense in you if you lived long enough to be called an "old guy" At least that's what my dad always says. Quote Link to comment Share on other sites More sharing options...
cheftrd Posted September 8, 2004 Share Posted September 8, 2004 RB26's will support up to 500hp with the stock bottom end. The stock pistons don't last long above this and will usually drop some ring lands. Forged pistons are a must at this level. When you add 272 cams to the mix, the engine makes peak power at around 7500-8000 rpm. It needs to be shifted at around 8500-9000. The stock rods will not tolerate this. Best case is the big end elongates and eats up bearings. Worst case..........you ventilate the block . The RPM's required to make over 650hp require rods to keep it breathing. 750hp requies a fully counterweighted crank. Unfortunately, the only fully counterweighted cranks are billet and cost upwards of $4500. This is not opinion, but experience. I've built A LOT of RB26's. 500's the max RELIABLE hp with the stock motor. There is no such thing as a "reliable" 1000+hp RB26. At this level, they are "PRO STOCK" and need lots of attention to make them live. Whenever my website goes up again, I'll be putting up a complete build-up of a 900+hp RB26. On the 2JZ......Toyota's casting and forging technology is incredible. Until you've opened one of these engines, you just won't get it. The crank is a fully countered awesome forging and the rods are dowel pinned, cap-screw forged I beams. The stock pistons are cast though, and are the limiting factor. The stock pistons will support 700hp. With just forged pistons, this engine will tolerate tremendous power and rpm's. 1000hp 2J's are a dime-a-dozen in Japan because they're relatively cheap to build. On that note, the same goes for many of Toyota's engines. I've got a few 500hp 1600cc 4AG's running around with only the addition of forged pistons and ARP rod and main bolts. These are 10,000 rpm engines. They're also no fun to drive to work. Haven't had a rod or crank failure yet. The 1JZ is essentially the same as the 2JZ with a shorter stroke. The 1UZ all aluminum V8's use the same stuff as the J engines, but have 6 bolt mains; 4 up and 2 through the side. Some of the 3SGT's and 4AG's even came with forged pistons form the factory. The castings on all of these blocks are so tight, they require essentially no clean-up. I don't read the car-toons, but Popular Hotrodding had an article recently comparing the Street Glow 1300hp 2J (Camry??) to a 500 inch, 1300hp Pro Stock motor. The car's et's and trap speeds were almost identical. They were amazed, though, because the 2J was using the stock block and crank. However, when asked about turbocharging the 500cid V8, the reply was 2500hp at the low end and 3500hp if it was serious....... Way outa my league...

Guest bastaad525 Posted September 8, 2004 Share Posted September 8, 2004 Very good info Cheftrd. Just no getting around the fact that Toyota makes the best engines!! Quote Link to comment Share on other sites More sharing options...
Tony D Posted September 8, 2004 Share Posted September 8, 2004 Amen, Chris, Amen! Pick up the top of a friend's skull and place it back on top of him while wiating for the cops and ambulance to arrive tends to change your prospective of even a "little friendly game of chase" between friends. While YOU may not take the confrontation very seriously, and only see it as "friendly fun" due to being totally mismatched in HP terms (say, a 72 Chrysler Newport 440 Convertible and a 69 VW Beetle with a 1500 Single Port and 4 200# occupants...)---on the street you never know what the OTHER guy will do. And that is a receipe for Tradgey. While some call it preaching, others look at it as trying to prevent others from ever having to do something that they will/can never forget, and could live without. Believe me, I could live without that memory. I could live very happily without that "life experience". Amen, Chris, Amen! Quote Link to comment Share on other sites More sharing options...
