ALRIGHT!! I’ve been doing a whole boat load of research these past few weeks. I’ve been doing the numbers, and rereading the thread to ensure I'm not missing a single bit of detail about building a 7AGE. I finally have a great list of what I'd like my 7AGE to be built out to be! Starting with the bo...

That 225-230 at .050" valve lift would be somewhere from 250-265 degrees total duration. Shoot for lift over 8mm that won't necessitate shim-under buckets. The lower end of that duration range should idle close to stock and the upper range can do well enough if you play with the timing. So the...

Try to keep your compression closer to 10.5-1 for a smog engine to keep the NO to a passable level. That was the reasoning for using the Late GZE pistons. I was thinking that a 10:1 or a 10.5:1 would’ve been the recommended CR for 91 gas but I will double check ALL my math before any purchases or w...

You mention 150hp... it might be possible to build an emissions compliant 150 flywheel hp, 150 wheel horsepower is out of the question, even with a 7A block. I meant it as brake horsepower. However if getting to 150bhp is harder than getting to 150fhp NA, lowering the power expectation is fine by m...

Oh dang you’re a good ways away from me! Does it get warm out there?

I've used Maxspeeding rods without issue. I've used the stock 7A rods without issue. The stock rods are actually stronger than would be expected, just prefer not using the press fit wrist pins. The "H" beam rods are indeed stronger and lighter. So would the stock rods be more beneficial t...

You get 8.5mm more stroke! The longer stroke will give you more torque and improved economy. The USDM 4AGE is rated at 98ftlbs of torque at (I think) 4300rpm and 112hp at (I think) 6600rpm. Building a 7AGE with the minimum steps necessary, head, pistons, crank timing sprocket, and the fitment mods,...

Get the best volume pump, late model 4AGE. Smooth the pump's oil galleys, and if you can, get the housing hard anodized and lap the gears into the pump body. Would the ST/BT oil pumps be considered the late model pumps? Which is better to use for a 7A? You inspired me to make a 7A which loops me ba...

What is your intended use for this car? The intended use is honestly everywhere. I want to daily it, track it, go on some long distance trips in it if I’m up for it, and just having a blast in something I made that I would consider a “tame” 4AGE build Or, if you are a bit more adventurous, look int...

The chassis itself will get some real goodies in the suspension department. Bob Pham’s 808 coilovers will be poison of choice with Poly bushings. For wheels and tires I’m going for Kansei KNP 15x7 +25 rims, and a good tire that is 195/50r15. If I can’t find anything in that size I will one up to 205...

First and foremost, introductions. Hey club4ag. This will be my first ever post here on this forum. I hope all of you are doing well for the holidays and hope you all had a great 2023! As the topic suggests, I am planning out a 4AGE build for my 1987 AW11 and I couldn’t be more stoked to get started...
