Hey guys, Thanks for all the replys. Now that I know what the dome CC is (15.5) I can calculate it. Does anyone know what the std deck clearence is on an RB26?? I had it written down but I am now traveling and would like to get this all sorted for when I get back home. Also, here in Canada, if its a dome top we always call it +cc if its dish top its -cc. Therefore, +cc decreses the total combustion chamber and -cc increases combustions chambers. Might be the other way around else where though. Thanks!

Hey guys, quick question: I am putting together an rb26 using CP pistons and an 87mm bore and .010" shaved off the block. Everything else is std sizes. I am looking for help getting the right head gasket thickness - I would like to end up with around 8.5:1. However, I can not find out what cc the dome of the pison is so I can not calculate it myself. I tried calling CP to get help on this but have a several attempts I couldn't wait any longer. Thanks

Excellent! Thanks for the help guys. I have a general idea now what its worth. When I say it's tight I mean it's pretty tight. You cant spin it with one finger....

Hey guys, I'm located in Canada and am trying to gauge the value on these turbos. (Theres not many for sale around Canada for me to gauge the value on) I have two R34 N1 turbos.. One is in great condition (minimal shaft play - spins great) and the other is very tight but has no wheel damge - it will have to be rebuilt. Does anyone have an idea what these things are worth? Thanks

Thanks for the replys. The reason I'm doing this is because I'm doing a major engine rebuild and couples with some other things I have going on right now new turbo(s) arn't in the budget right now. Within the next year I hope to have new turbo(s). Don Dada is correct that all the GTR turbos started with 14411.. So, I'm not sure that could be the CHRA number. Although, it sure would be great if it was haha.

I asked this on the Canada forum but I thought I should ask this here aswell: I'm hoping someone has some experience with this... I have a pair of R34 N1 turbos (14411 AA402), one in great condition and one that is very tight. No damage on the compressor wheel or turbine. I was looking at replacing the CHRA on the tight turbo but prices are outrageous and to be honest I'm unsure that I can find the right part. However, I also have a pair of regular R34 GTR turbos (14411 AA300) that are both in great condition. I am wondering if it is possible to use one the CHRAs from the regular R34 GTR tubos and replace the turbine/compressor wheel from the N1 turbos. Does anyone know for sure if this is possible? If it's possible it sure would be great lol. Thanks in advance.

Hi guys, Thanks for the replys. What I was refering to as the "lifter bore" would be the bore that the actual bore that the valve spring and the lifter sit in. I'm in Canada, perhaps you guys call them a diffrent name in Australia. I guess what I'm asking is: Does this require actual machining or will "play it by eye" method work? Thanks

Hi guys, Quick question, what tools are you guys using to notch the lifter bores to allow for large camshafts? I've heard of guys using milling machines, CNC machines, belt grinders, ect ect. The reason I'm asking is because I was planning to use a die grinder with a carbide cutter (same stuff I use for port/polishing). Does anyone see a problem with this? Thanks.
