Hey all,

I have a 33 gtr and I'm looking to add some cams.

I'm going for tomei as no extra work is needed just drop in.

But I'm unsure to go type a or type b.

I'm not the most mechanically minded so reading specs isn't helping me.

What would I notice in the way of difference installing one over the other?

Which should I go for?

My set up is a forged rb26

-5s with the bolt ons making 340rwks at 18psi

Does make more power with less boost.

Tough idle.

better midrange and topend.

Check out the RB26 dyno thread. You'll find my graph (tomei type b) and my mate's Sloane, similar cams, and other similar setups.

Will it make it any more responsive? More torque? More kws? Etc?

On the street or a dyno?

I know two people who took them out (for stock), went faster around Sandown. You be the judge, it's not just about dyno plots when fully loaded.

I've said that enough over the years so I'll leave it at that.

Or keep the stock cams, tune to 22-24psi and see how much it makes then.

If it's 360+ keep the stock cams.....

If you want to push over 390-400 the stockers may need replacing.

In the end it is up to you.

Such contradicting info out there over cams! My tuner said i should get them but others say dont bother etc.

The car is a daily driver with drags on the weekend in mind.

Also while people are reading, my boost controller is a AVC-R, ive never had one before. does it allow for a high / low boost settings? ie 17 - 18 psi daily. 21 psi drag day?

You can have either high, low or off setting, all this depends on your wastegate spring of course, its a good controller, in your lower gears like second you can increase the duty to fine tune, you can ramp it up early too just be careful if you dont know what your doing...

Yup strongly agree with this I found out real quick what over boosting was when first attempting to use the avcr who ever ends up tuning get them to show you

    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
