And another question... I would like to put wisecos because they are cheap.. What compression I will have with stock headgasket with R33 RB25 pistons? RB26 pistons? Here there are the spec of the pistons... I don't know how to calculate the ratio so anyone how knows please let me know! http://www.wiseco.com/PDFs/Catalogs/SC08/N...aruToyotaVW.pdf

NEO has cable throtle body like R33 or wire (as new technology cars) ? Can I put Q45 throttle body ?? (in greddy intake manifold)

Just I don't want to spend money in the head...! Only I will change seals and I change what ever is worn! No cams no headwork! If after some years I want extreme power I will spend money and at the head! For 500-600 engine hp I know that stock head both 25 and 26 is enought, right? But my problem is what to choose... not if I do somethin with the head..! Come on guys!! Please help me with your knowledge

I told that both 25 or 26 will be with FORGED pistons and rods and full rebuild! Ok RB26 have huge advantages..! But what they are? Let's start a list: -Better flowing head -6 throtle bodies (lest the q45 will be good too?) -intake manifold (rb25 with greddy intake will do the same job) -Remappable ecu -They have the same block? -What about electronis? -Ι don't mind for 50cc more of the 26 I don't think that the advantages of this list are HUGE! We don't compare stock engines... we compare tuned engines! I know that 600 engine HP can handle a stock 26 but the 26 that I find to buy will need full rebuild for sure work! I will do whatever you say me I told you above the prices and what exactly I will get with 26 and with 25! If 25 and 26 have really HUGE differences I will go for 26 but I want to know the HUGE differences to know what I do

Guys thanks for your replies! But maybe you can help me more if I tell more about what I have to choose! Also I am from Greece... I don't know what is LS1 and 2 and sure I cannot find it easy.. also I don't want rb30! RB26DETT from Greece 5.000AUD Condition" It has problem at crank(stock oil pump and hard driving )... it needs rebuilt..! So I can buy from AU or UK a second hand crank and forged pistons-rods, stock gasket kit, acl bearings! PROS Also it has twin plate hks (unknown condition but new discs aren't very expensive right? ) It has repaired turbos with steal wheels and I can sell them! He said that it has something like extra ecu, bullshit sure but I can remap the stock ecu as far as I want! CONS IT HAS RB20 GEARBOX!!! :| :| :| :| I can sell it about 500-600aud I think here in Greece at 200sx boys and then I can buy one rb25 gearbox for 1100AUD RB25DET NEO from UK Including 4.100AUD+300Shipping Condition: Mint condition stock I have bought greddy intake with 90mm q45 throtle body and stock gasket kit (but I hope that I can sell them if I choose 26) I also will need pistons and rods and bearings as the 26 to have a safe motor! PROS RB25 Gearbox NEO engine!! Fresh and better than r33s! CONS NEO engine have some incompatibility with r33 aftermarket parts! TARGET For now 500-600HP! But potential for quite more.. I don't want never to spend money for the head.. no cams, no headwork, nothing at all! The "house" of the RB will be my 180sx S13 everyday car but I love Drag Strip and I want to see my car to run high 10s!!!! Sorry for the gabble! Hehe my target is high 10 and I don't mind for hp! Can I do it with stock rb25 gearbox? I don't want weight reduction! I have Hoosier Drag Radial 225-50-15 and I don't want to spend money for larger tires.. I want to do high 10 without crazy low 60foots! Think that I did 2.0 with 350hp and toyo r888 225-45-17!

The following R33 parts... Greddy intake fit to neo? Clutch for fits to neo? Forged pistons for r33 fits to neo? Exhaust manifold fits to neo? Nissan OEM gasket kit fits to neo? That's all

What to choose guys? Don't think the money... only the result! If I have the same forged pistons and rods (e.g. wiseco+eagle) either on rb26 or rb25 what I will have better if I choose rb26 engine? The power that I want is 500-600 for now but I want to know the power limits of the engine for later...!

I am looking for rb26dett gtr rods! Please send me fotos to my email [email protected] Also I am looking for rb25det forged pistons in good price

Ok maybe it will cost and more... but I don't ask you tell me how much will cost! I ask many questions... can anyone reply me please? Please I need replies in all of my question... they are very important for me..! Also I need ecu as my tunner said me that it cannot remapping the stock..! Emanage choice is good? Can I have launch control for drag strip? Can it increase rev limiter (because a friend told me that it cannot)? Also I don't need 300zx maf right? Can I run with only the map sensor or it needs the stock maf?

Man you don't help me...! I don't ask abou the costs... I ask many other questions.... Also I see that you always talk for WHP in this forum! I talk for CRANK HP! I would be happy to help me!!!

Hi guys, I bought a rb25det engine with box for my S13!! I am looking for over 500hp for drag strip and everyday car! I will for the begining that I don't have much money to spend and I also want a safe motor! Where is the limit of the stock pistons? How much horses can handle with good rich mapping (high 11 afrs?) ? And where is the limit of the stock rods? How many rpm can handle and how can I avoid any damage of them with my driving? Can I strengh the rod's limits with changing the bolts with arp? I read somewhere this but please confirm this to me I will work with stock cams and head! The parts I will order are: Greddy style intake Q45 throttle body XS Power top mount manifold (I will increase it strengh with a "help bar" and some extra welds) JUN Crank Collar N1 oil pump Tomei oil gallery ofrice (and I will block one oil feed and I will increase the flow of the oil return) 52mm koyo style cooler I have fmic from my previous motor with core 600x300x76mm and if you think that it isn't enough I can put a same with 100mm core! I am from Greece and the climate here is quite hot. My exhaust is 3"! Enough? I have walbro fuel pump and as I read I need a fuel pressure regulator because stock of rb can't control the big fuel pressure of the walbro! 555cc injectors and 300zx maf and remapping the stock ecu. And I will try to buy a twin plate clutch kit instead to buy a single ACT even then I read that act can handle 500hp! If I will buy a twin plate maybe I will buy Also I bought a gasket kit to replace everything! Also head gasket I will leave the stock.. what limits it have? I read something for 1.2bar boost! I don't know yet what turbo to use....! Garret choices: GT3076 I think that with this I couldn't go more than 520hp.. GT3582 Garret says 400-600hp according the housing...! Greedy TD06 25!! At 1.15bar with absolutely stock motor got 500bhp!! Anyone knows how much more can go with more boost? Turbonetics GT-K 550!! I love the look of this turbo! 500-600hp rated! Also any help with the garret turbos what horsepower you can think that can give with the same boost to compare and with what compressor housing? (1.1-1.2 bar) Garret's are also cheaper choice! Also please tell me your comments for my choices, tell me what else I will need and help as much as you can

Ok ok.. I ask it because Ι thought that it is too much too have an exterior oil return..! As I I will have the crank out of the engine do you think that it is good to make a balancing on the crank? RB cranks need it?

Hehe thanks for your reply... so I will buy it too! I read somewhere that it needs welding... is it true?? Also any reply in my other question about the oil returns???

I read the most posts of the topic.. I have an RB25DET and I will make a rebuild theese days...! The changes I will do is: N1 oil pump Block rear feed 1.5mm Tomei Oil Gallery Orifice at Front feed External oil return Improve oil flow in the cyllinder head return galleries But I don't see any post for oil pump collar..! I need a JUN oil pump crank collar?? Also with external oil return and improved oil flow in the cyllinder head return galleries les is too much oil return?? You are 100% that I will have it any problem at head at low rpms? I use my car for everyday in traffic, for travelling but and drag,drift,cirquit and I will go for 500hp!!
