I think holding on to 7M's is good for some people. I think it's admirable, and old age of the engine, the rebuilding process, trial and error, smaller aftermarket which is slowly growing due to a higher demand of younger drivers, cheaper... it just seems like the 7M is just a thing of the past with other people, including me. I don't like the piston speeds, but that's just me thinking the 7M is too stroked for it's own good at 8,000 rpms. Just look at pistons speeds.... The 2JZ stock can rev to 8,000 rpms relatively savely. The springs can take it too.
Hell, Zazzn revved some 2JZ Large Core Crower 272, 10mm lift cams on STOCK 1JZ valvetrain to 8400rpms with no ill effects (1JZ/2JZ... very similar).
Dave Henry has used a 220,000 mile 2JZ-GE engine and pulled 9's in his SC300. A lot are in the 10's on stock bottom ends. Lucky? Maybe, but considering a lot of 2JZ-GTE/GE guys are doing the same thing, slapping on turbos and EMS units, and getting their JZ engines tuned and running fast times makes me think a lot of them are just lucky. Go to a junkyard, JDM, or hell, use your engine figgie, but find a 7M that has been "maintained" the best it has, and go for 10's, but make sure you you do it right, or get lucky. Maybe all 7M enthusiasts are doing something wrong with performance, not blaming the engine for a single fault. Slap the same turbo on the 7M motor, and go for 10's, use any standalone you want.
Which would hold more power reliably? Which will give you a sub 10 second car first, and last longer on conservative tunes?
I really wish some people knew how to care for their 7M's, and actually make them fast without going into the engine, without porting the head. Maybe Will N. did it with 730rwhp, but how many have matched it? VERY FEW. I wish the 7M's weren't 15 years old with heads that don't come close to matching the flow of the 2JZ head, GE or GTE stock for stock. Defiant7M might have a great flowing head, wow, he's one of the few..... Because the 7M head sucks ass for flow. Now if you ported a 2JZ-GTE head the same way? Then you can potentially make 1400RWHP++ like MKIV guys are doing. EDIT* so ONE 7M made 1350, and you're using that to make a point? More than ONE MKIV peak HP numbers are higher than that, so there, 1350RWHP 7M owned by 2JZ.
I wish someone would see how much power the stock 7M block can handle before it blows up, which was what around 700RHWP or something on a junkyard motor? 100RWHP cruising on the highway? 2JZ has been to 900RWHP? Maybe it was luck, or the idiot 7M guy did something wrong, again, and again, and again......
All of these point proving 7M owners who keep rebuilding their engines to go faster longer.... I guess (insert all 700RWHP 7M owners here) and others should have just done a better job at maintaining their engines, because they've ALL had to build them up to hit their marks, and many are on their third, fourth, hell they've gone through a lot and spent so much, which compared to a 2JZ is not anything to brag about, just ask any of the big 7M players on any forum, they will all tell you to build the 7M up, even for 600RWHP. I'm confused as to why, I thought the 7M was on the same level as the 2JZ*.
Why do people have posts on Supramania and Supraforums, EVEN Celicasupras with upgrading the 7M oiling system? Now come on figgie, you aren't going deny that those who supported those "7M oiling issues" threads by showing pictures of -AN lines inside their blocks, or using NA filter studs, and installing remote thermostats, larger filters, etc. are a bunch of pointless 7M engineers improving on a "INGENEOUS" design, they must be making a mistake.... if the 7M design was so "INGENEOUS" why fail to mention all of the high HP 7M guys for mofidying the stock 7M oiling system?
I don't see 2JZ threads say "2JZ oiling issues" anywhere on any forum? Dang, maybe the 7M OWNERS are all to blame. I wish the JZ series engines had retained the 7M oiling system, then I would be happy all Toyota engines suffered the same problems, and let the 2JZ guys spend money on it and fix it for us, but wait, then they'd be improving on a INGENEOUS design, how pointless*******
Figgie, is your oiling system 100% stock? Did you somehow improve it? Dr. Jonez still runs the stock cooler bypass? NO? GASP, Dr. Jonez runs a NA filter mount stub, mocal sandwich thermo, -10 lines and a huge cooler. he sees 15 psi @ idle and well over 60 by 3k, WTF???? Figgie, better tell him that high pressure hurts flow or just leave people to believe what they want, the information is out there.
This thread is getting anti 2JZ, hell figgie, even anti-AEM, wtf? You aren't the only die hard 7M lover around, stop bashing in someone's build thread. Nobody's plan is perfect and if you aren't going to support anyone and go out of your way to make someone's promising project look like a bad idea because they are jaded on 7M's, what are you really contributing? Let 7M/1JZ/2JZ owners research and decide what's best for them, like they have for years. It's apples and oranges, and to each their own.
