Well... I lied.. they are from a 2jz. A friend of mine owns a mk4, and builds it up more all the time. So, often, I get to pick up his used parts for a GREAT price, and I know they were well taken care of.....
On to the pics!
720 CC injectors! I will be making my own custom fuel rail (dual inlet, center return, 2 Walbro's)
AND...
A machined aluminum crank pully! to say it is lighter then the stock one, is an understatement. I hope to see some response from this thing (quicker reving) but I am not sure how much improvement.....
Hope ya enjoyed it. I might be picking up a 2jz RPS pressure plate, and RPS aluminum flywheel, to use with my SPEC stage 3 disk.... but I'm not sure.
After reading about failures when using this crank pully... Im not so sure I want to use it.........I think I will make sure it is ballanced before I install it.
Matt and CK, I am ordering the fuel rails this week, and then off to the mach shop to get milled...Let me know if youre interested, matt, you and I already talked about this, dual in, center out. LMK bitches, these rails will be overkill fo sho enough to supply my 1600's
I also noticed this Aluminum pully is an underdrive pulley. After reading peoples responses on the other post, I think I will put it on. Ill check and see if it's ballanced first, then on it goes!
OH, and BTW... stock pulley weighs 9.2 pounds. Aftermarket, 3.2... so i will be saving 6 pounds. which is allot of rotating wieght!
actually, making a fuel rail will be cake... ive already outlined it several times in other posts.
all you need is fuel rail stock with 5/8" ID, thread the ends for 5/8" NPT to -10 AN adaptors. install six 3/8" hose barbs with pipe thread and connect to top feed injectors via short length of fuel injection hose.
its a pretty simple concept and works like a charm. no need for super expensive madd tyte jdm parts or anything.
W'sup everyone,

Non-VVTi 1JZ-GTE here with 87,000 km's
Car starts up and fires perfectly fine, and no idling issues at all. Runs great except when I'm brake to a stop in neutral, to which I have to start it right back up again.
It doesn't happen all the time, but it is very annoying. Is this usually a...
1jz Vvti
This is on the Turbo side of the block, I have no idea what its for or what it does or what I should do with it?
Please let me know thank you!
Noticed that under load my 1JZ is bogging right at the transition point of positive boost. It almost backfires slightly depending on load, but once under boost runs like a scaled ape...
The on/off transition seems more single-turbo like than the normal smooth twin action. I had originaly...
Well, I have a Lexus gs300 with over 200k miles. I was going to turbo the engine, and when I took off the throttle body I seen oil. And also in the spark plugs, then I continued to remove things. Till I took off the intake manifold, so they had oil in there as well ? Crack heads ?
enough to supply my 1600's
