Yes indeed ; They offered it to me, I'm waiting for their quote 😉

I see what you mean !! 👍 so I drive with E85 AND E100 my cylinder head and full supertech with 270° camshaft and 10.25 lift this weekend I spoke with my mapper and he told me 10 ratio would be even better so I went to set up a setup with : 3.2l crankshaft from expensive spool import with a stroke of 91mm Nitto or IRP connecting rods length 152.5 mm and piston irp ratio of 10 after having the information near spool import the setup did not work because of the crankshaft which is 91 mm therefore the assembly mounted in the engine block will come out 1mm high above the cylinder head gasket surface so I have to review the construction of the lower engine low IRP is Italian I am French I wanted to limit the costs because as they are in Europe I do not have customs fees to pay 🤷‍♀️

Thank you for your answers 👌

yes you are right, indeed it is for information only. there is not much difference being at 9 or 9.5 or 10. but when I see that you have to plane the block by 2mm if you have taken (example) CP piston which means that you end up with an 8.2 with the rb26 cylinder head. hence the question I ask is what would be best to achieve what he is asking me. take pistons in 9.0 or 10.0 to avoid planing a famous 2mm on the block knowing that I worked on the dome of the cylinder head which became total hemispherical

Hello everyone , I am currently building a 3.2 L with an RB26 cylinder head my block is stock and I will run E85 and E100 My mapper who is Romain Levesque from dear RaceCAL LtD (former syvecs technical director) asks me to make a ratio of around 9.5. so after reading a lot of topics on it I found pistons with a CR 9.0 and 10.0 expensive IRP what direction would be taken to achieve a ratio of 9.5 without having to plane the block by 2mm or to do it a minimum, but to be able to play with the thickness of the cylinder head gaskets thank you in advance for your response

thank you GTSBoy, I'm going to do as you told me with my rigid rules. afterward I did as it was just to see if my block is still valid or not, otherwise it won't be much use to me to work on it It would only be better with your method thank you once again, I hope there will be people who will respond too I will see

Hello everyone , I am looking for the height rating of the RB30, because I would like to know if mine has already been planed or not mine placed on my marble is approximately 286 millimeters and the shirt is 152 millimeters

Yes, the Nissan engineers didn't have the courage but did everything to ensure that others like you faced it. was impressed that they were told not to do it at that time out of conviction that it would not work

Duncan 🙏down here it is!! I feel better !! yes it comes from a patrol y60 so actually I would like to keep my 4-wheel drive, in fact I vaguely looked at this story of adapted housing and I found expensive HI OCTANE DIRECT who are apparently the only ones to do it for 4 wheels! even if I could do it with time since I work with metal. (but sometimes you have to avoid getting pissed off to be productive) after my crankcase is already modified with a raised greddy crankcase and internally I have a tomei partition and my strainer and already modified for my greddy crankcase so not even afraid of this step.💪 I have a milling machine in my workshop so it should be done for this modification side so I also looked for the getrag r34 gtr gearbox (yes I switched to gearbox 6 on my r33 for a few years) manual because in vhc (historic vehicle the sequential gearbox is not allowed) so I also looked for the getrag r34 gtr gearbox (yes I switched to gearbox 6 on my r33 for a few years) manual because in vhc (historic vehicle the sequential gearbox is not allowed) I noticed that the head of the 4 wheel drive return shaft doesn't have much space so it's complicated so I'm going to buy this plate and not waste time on it This is my priority. while focusing on preparing the lower engine to accept my cylinder head and my Tomei Procam 272 camshafts to have a ratio of approximately 9.50, it looks complicated to me so I have to pull my hair but I like it

thank you niZmo-Man but you're scaring me, are you telling me that the block I found isn't the right one in the rb30 series?! I would have difficulty building it compared to an RB30S for example?! Afterwards I actually saw that it was rich and that the remaining oil was well burned... this one was mounted with a large double body carburetor the cylinder head is new but the surprise was by removing the cylinder head and the pistons the lower engine was not new and the water passage I don't even talk about it .... So this weekend I'm going to try to wash and remove the sandblasting tablet before starting anything if you reassure me about my block because now you're making me doubt

thank you for your compliments.😍 hi duncan !! I'm not going to hide from you that I already searched the forum before registering..😉 hi prank !! I already have the engine, I found it on ebay a seller of Spanish wrecks for 1000 euros delivered it to me in my workshop it appears to be original. I found an RTA but there is not everything on it to check the bass ratings of the engine so I hope to find or have my answers here. It's apparently an RB30 S2 that was tinkered with. the cylinder head was mounted with a carburetor with two valves on the bottom of the engine, it had 4 valve impressions Afterwards it is not very young but I think with a little elbow grease I should be able to do something with it if not I would like to be able to come to your country one day just to be able to drive on your legendary Barthurst circuit in a v8 supercar or with your monstrous trucks

Let me introduce myself, my name is Christophe, 51 years old, I am an independent boilermaker welder. I apologize because my English is not great so I am going through a translator for some sentences, I hope I can make myself understood I have owned an R33 GTR V-spec for over 10 years now, not as extreme as some of you but for us in France it is a nugget worth gold because it was. not marketed. it in the colors of that of gran turismo 3 I do the track with it has a small 2.6l of 570hp and 630 NM unfortunately I broke my block a few months ago so I registered to find information on the construction of the famous RB30 with conversion of the RB26 cylinder head. because dear to us there are not many people who have made RB30s themselves... Today I would like to have around 800 hp if that tells you; I can give a description of my car because there are quite a few parts on it, from the chassis to the engine including the complete syvecs s6gp management I hope the questions will be relevant and will not be repeated over and over again. looking forward to discussing with you christophe
