Iv got my rb25det s2 r33 and has 650cc inj, bosch pump, dsr430 turbo, fmic, linkg4 etc

Was wondering if straight drop in 272deg. 8.4mm lift camshafts are too big for my setup?

Iv tried searching...but doesnt quite make sense to me... what deg cams would i want for my setup? because will 272deg make power too late in the rev range? or...?

im hopeing for about 275+ at the wheel...

thankyou

I know there massive...but would they do anything being that big?

if u get gears and dial them in, you can definately get them to work for you.. the secret to anything good is R n D, and I cant say I have much faith in how much research OR development has gone into those.. never heard of em to be honest.

thats not to say their shit, try find someone else using them and go from their results.

If your hoping for 275, stock cams will be fine.

Camtech do 272/9mm lift for 25's.

but I really think its pointless at that power level.

Its been said time and time again stock cams have worked well at 370kw's +

money could be spent better else where on the car!

Well whats somthing else that could be better spent on the car power wise? i would like some advice! :P

you will be fine, dont know about that turbo tho. My mechanic worked on a 25 with 270 tomei cams, sure the had more lift, but his power delivery wasnt too bad. Definitely useable.

But that was with a gt35r

Is the turbo you have specced capable of making the desired power level?

Money is best spent getting that right.

Looks like a Chinese style 430hp turbo... so highly unlikely it will make 275rwkw.

Probably closer to 230-240rwkw with a nice taste of lag.

No turbo that costs $450 AUD is going to be nice...

I mean the cams just about cost more than the damn turbo... that's just telling you there is something seriously wrong :P

OP - Forget the CAMS, and spend the money on a DECENT turbo.

The turbo claims to make 270rwkw on an rb25det...and they have some dynos for it too... i know its still a cheap turbo and a decent turbo is the way to go but i dont have that much to pay for a big pricetag turbo...but i know i shudnt skimp out on somthing so important...but this turbo seems to look like it will do the trick? if what they claim is true....

heres a dyno sheet off there website

^ Hub dyno mate, it's not RWKW.

So if you spend the CAMS money onto the turbo, a nice decent Garrett or similar, then the car would perform much better in all respects.

You'll probably still be shy another $400-500, so perhaps save up that little bit more on top and then do it once you have the cash together.

A GT3071 would be what you are after IMO. A nice 260rwkw, would be superb streeter.

Take 10rwkw off that dyno sheet as they are using DIN which is an old correction factor (what the US uses), it should be in SAE J1349

    • Yeah good luck out there! Will be good to see a mighty GTST going harder than the GTRs
    • i will be there 😁
    • Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4
    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
