cams on stock 1jz

[supramike7m]

hey guys, i searched but didnt really find much. just wondering who has put upgraded cams on a basically stock 1jz? ive got intake, full 3" turbos back exhaust, and profec e01. what kind of gains could i expect. for the money i figured id rather go for cams and not intercooler and hardpipes. thanks

thanks bro, the first one i saw, but that with upgraded twins and the whole 9 yards. i seen the second link before and was just looking for it. im actually looking to see what kind of gains people are getting with aftermarket, not 2jz cams, on a nearly stock 1jz. just wondering if its worth it on stock or nearly stock 1jz? 2nd link helps some though. thanks

If your just BPU, I'd go with the machined 2JZ cams. We all know that the 1jz power drops off after 6000 rpm's. The 2jz cams will keep the powerband going to redline. Plus add some HP throughout the powerband. Good luck.

i just dont see how cams could be questioned. little mods or not. unless you want better gas mileage, cams are always good in my opinion.

till this day, best performance part i've ever bought.

yep, I agree.

not questioning at all about them. just want to see some kind of results for aftermarket cams on nearly stock 1jz.

I noticed I hit full boost about 300rpm later with my Crower 272s on stock twins, however I made power past 7k, where as it used to fall on its face around 6300. Made some huge gains under the curve. Dropped my E/Ts bout 3 tenths.

Car was a dog below 1500rpm, had to add a little fuel, and advance the timing to help it, but you can live with it stock. Made for quite the lumpy idle too.

Interesting side effect, boost actually dropped due to the motor being able to suck in so much more air.

I highly recommend cams being the second mod everyone sould do on a 1JZ (first being y-pipe).

haha. I advise cams to be the 2nd as well. 1st mod should be single turbo :lol:

I've got the crower 272 small cores and they are the shit. Like Matt said, it's slow at first, but they more than make up for them on the top end.

 

[str8_6]

yeah, it screams! i to notice decrease in low end and turbo spool up, but you forget about it once your head is slammed back into the seat. it shuts you up.

lumpy idle is da bomb. i did have to dril a 3/16 hole in my throttle plate to increase cold idle (courtesy of hamsmkiii mentioning it).

dylan jz- 272 small core all the way. go big or go home..hehe.

haha. Well my first 1JZ had an HKS GT3040 single turbo kit.:sarcasm:

The more you guys talk about cams makes me want them just that much more. For the price and the gains it seems like the best bang for your buck mod on the 1jz.
