just curious because my mate has just got hold of a 30 block and wants to put it in his r34... but has heard that the neo head is not a good option because of the shim and bucket set up inside the head(aluminum intake buckets).

Doing one at the moment, i feel they are definately superior to the r33 head fr that reason. Ive fitted gtr cams. You just have to cc the head, as the bowls are much smaller than the r33 head, so you end up using rb30et turbo pistons and end up with mid 8's comp.

He's sourced a good bottom end, and thats at the machine shop.

At the moment he's aiming for around 600hp at the crank.

Still deciding on turbo.

im also thinking about using my neo head....because they have smaller combustion chamber means that the comp ratio will be higher then that off a r33? I need alittle help in finding the right pistions to give the best comp ration...Will be using t04z and pushing 2.2 bar max...I would still use my hks gasket 1.2mm...

cheers

Whats the question? rb30 pistons wont cut it, the comp ends up too high. If you plan on using a 1.2m headgasket to drop it, it wont be anywhere enough, and is the wrong way of going about it. RB30ET forged pistons work out about right in the comp, at between 8.3 and 8.6 depending on what headgasket you use, how much the head/block get skimmed during the build, and the specific brand of piston.

email me for any info you require.

The RB26 pistons will give very high comp ratio due to the R34's small combustion chamber.

They are not an option really.

Yep, he ain't using those pistons anymore, as they are wrong for the job......

    • I'm so far behind in the jobs I have to do at both work and home (including car) that I have become immortal. There's simply no way that I can die now.
    • Each to their own I guess  Me, I put just as much time into cleaning inside of the cars as I do on the outside As for getting wet, it is really no different than steam cleaning the carpets at home, apart from the cars carpet dries alot faster than the house, again, I only do it in the hotter months and leave the car opened up for a few hours As I only do it yearly, it is just before I do the diff and gearbox service, so I clean the carpets, then it's up on stands, wheels off, service, clean the undercarriage,  grease the bushings and do a nut and bolt check on everything  Disclaimer: I typically had all the time in the world to kill when I was working 🤣, so spending a full day or 2 cleaning, serving and "looking at stuff" was,  easily achievable, and a fun mental therapy day As for time to kill, I retired last Wednesday, so apart from my physical training, my days are filled with lots of random jobs around the house and garden...."Idle hands are the Devils something something" I am also buying a new house sooner rather than later, I'm actually looking at a potential property tomorrow, I'm looking forward to getting a car hoist as I'm starting to get to old to crawl around under a car, I can only imagine all the undercarriage cleaning and looking at stuff when that gets set up
    • Yeah, I'm not interested in wetting the carpets, and I don't care about brown dirt/dust that lives deep in the pile or underneath. It's not like I crawl around on them in my birthday suit or eat dropped food off them (because there is never any open food in my car). The seats are alcantara (cheap Chinese imitation alcantara, to be sure!) with barely 1" of foam pad behind the surface. That's not getting wet either. Any car that I would be happy to get the interior wet, I would not care to put the effort into.
    • We have one that holds 2.8L of water. On floor carpet that hasn't been touched in 2 or 3 years, will take a minimum of 2 fills of the tank to do a bedroom, and that's going AROUND the bed.   In the cruiser, I used an ENTIRE 2.8L tank, just on the front passenger footwell. But it had some fungus growing, and had been full of mud from being used as a 4WD for many years. I can do that floor again, and it will still pull mud out. However, the water now only looks dirty, not pitch black and leaving full sludge in the bottom of the tank it sucks back into. Oh, and, this is about a $1500 unit.
    • This is mine, works a treat for the cars, suction is good, I use the Bissell clean and protect stuff I have found giving it a good spray and light scrub with the soft brush on the head of the nossle for carpet, and a rub with a microfibre for cloth seats and cloth door trims, prior to another quick spray before vacuuming it up works the best @GTSBoy You would surprised on what it gets out of carpet and seats that actually "look" clean, I recommend that you test drive yours when you have a little time to kill, then post pics of the muddy looking water that I believe you will find
