Hmm so a sr20det weighs 490lbs + intercooler= 220-450 hp. Aluminum head chevy 400 - 500hp easy with a 5speed tremec weighs 500? Doesn't make the chevy seem so big comparing it that way. Of course you would need a heavier diff. That might change my plans. Just happen to have 1.
I thought I'd pipe in with some SR20DET information since I have quite a bit.
Here is an SR20DET bottom end with an SR20VE head (a tad bit heavier than a DET head due to the VVL stuff, but probably no more than 3-5 lbs). Engine has a Quest 120 A alternator (1.2 lbs heavier than stock), aluminum crank pulley, no upper intake manifold (4 lbs). No flywheel or clutch.
Weight as seen is 254 lbs with some of the chain on there, so about 250 lbs in reality:Engine full up ready to go minus wiring harness (which is 5 lbs for the engine - from scratch harness). This has a 7.25" Tilton cerametallic twin disk, AP Racing flywheel (~8 lbs), stock SR20DET 5 speed, Quest alternator (120 A), VVL head, Full-Race twin scroll SR20VE manifold (~14 lbs), Borg Warner EFR 7163 T4 twin scroll IWG turbo, engine mounts, trans crossmember, and shifter. So as full up as it gets minus wiring harness (5 lbs).
Weight as seen is 423 lbs:A stock turbo manifold is ~9 lbs, or 5 lbs lighter, stock turbo is about the same weight, as the bigger EFR has an aluminum center housing. A stock flywheel and clutch is probably around 18-20 lbs heavier.
A belt driven PS pump with bracket and pulley is 7 lbs. I was using an EHPS from an Astra, but went to the belt driven pump later.
I'm not sure where the high 400 lb ranges I've seen, as even going with a heavy flywheel and PS pump, you're at around 450 lbs. Maybe with an AC compressor and bracket you can edge up near 480 lbs?
So that's what I've got. I used two bathroom scales that seemed to agreed +/- 1 lb in the 170 lb range, so I'll call the total weight +/- 3 lbs, but has a bit of wood and chain on it, so they're likely a bit high to reality.
