oh yaaaaah those are the info i was looking for thanks (GTSBoy) ..... And yes you are right the first thing i noticed is that the turbo oil drain has a connection in the engine block not in the oil sump so i think i'm a little bit relieved that this is actually a DTE engine until i get the engine from Dubai and open the intake and exhaust manifold and compare the ports sizes and i can make a compression test after i done the wiring to be completely sure about that . for identifying a s1 or s2 wiring .. beside the big ignition box you can find in the s1 (which is very noticeable ) i found out that the MAP sensor in s1 have 5 wires connection and in s2 it has only 3 wires. and after googling for some time i found this great site for identifying the ECU http://www.rbparts.co.nz/342746/ for the rb20 gear box i hope it lasts some time before the big boooooom ,, then i will get the big box of the 25's thx for all for the great feed back and if any one have some tips for this project (Peugeot 504 with a RB25DET ) pleas let me know

so..... this is my first rb25det neo (RWD) engine and i will fix it in a peugeot 504 - 76 but i have some questions to the rb specialist i know there is a lot of info. on the internet for this engines but i'm totally lost and i want some one to simply answer this questions : 1- what is difference (mechanically and electrically ) between the neo and non neo engines? 2- did the neo engines came in R33 or it only came in R34 and starting from what models??? 3- how can i make sure that my engine is originally a DET engine ??? 4- what is the difference between s1 and s2 engines? 5- what is the ECU serial number which matches my Rb25 det neo (because i got the engine with a harness only )? 6- i bought an rb20 gear box with this engine because of the lake of resources (money) is this will be a problem in the future ? 7- what is the difference between an automatic and a manual transmission engine harness and how can i know which harness i have? 8- i need a full wiring diagram for this engine as the wiring is the most challenging thing for me (fixing the motor into the car is the easy part). this acutely summon my doubts for now any help from you guys will be very appreciated if any one have any info for me for fixing an rb engine into my car please let me know __________________________ proud to be a RB owner ____________________________
