i looked on page 6, nothing... i remember them being on page one at some point, couldn't find them. that freaking thread is almost like a mini forums in of itself! the search button doesn't let you search for small terms like 2jz and it crapped out this morning.
I just finished having 2J cams put in the 1j in my GS300. Cost me $70 for a local shop to machine the ends down. Went with a Greddy timing belt while we were in there.
Picked up 20hp at the rear wheels from 5k up. Feels like I picked up quite a bit below that, as well, but it doesn't show on the dyno graph. The operator said he had to feather it up, to keep the trans from downshifting. Torque was up about 15-18 as well.
Actual peak numbers are 257 hp, 251 TQ. Stock twins, SAFC, 12 lbs.
Great mod, if you ask me. I picked up the 2J cams from Titan for $160.
I am getting my 2J cams machined right now, they should be done next week. You need to machine down the cam seal surface a few mm on both cams, and widen the front journal on the exhaust cam a bit. Your machinists are cheap, the cam guy I took mine to wants like $150-175 !!!. I will post my results when i have redynoed. I cant wait to see the gains from the cams when using 500rwhp as a baseline, I have only seen dyno's from basicly stock 1jz's with the mk4 cams.
I can't wait until I throw them in. 20rwhp from 5k and up would be UNREAL on my car. I can't even imagine what it will pull like (2900lb mk2). What were the engineers thinking when they put in 189 cams on a revvy motor like the 1J?
I used to have the specs on both cams back when i first put them in my ex's car... i dont know if the thread is still around. but the 2j cams are guaranteed top-end power gains. the car pulls just as hard in the top end as it did in the mid range w/ the 2j cams
i want to say that the cam seal journal needs to be machined down 0.100", same for the back side of the thrust surface... but this was like 2 years ago that i had this done. btw, the cams were only $80 from a fellow SF member and the machine work was $60. its only about an hour's worth of work for both cams.
