when i got the head the place told me it was rb25 but as we got through the build found out it was a 20. doesnt seem to hurt performance and boost comes really quickly so dont know how a 25 would have gone compared to this but not gona complain. besides when i get the head worked and ported it will flow plenty enuff for what i need. |

Beautiful VL mate Glad you like my photos of your car. QUOTE R32 RB25 head runs the RB20DET style ports but larger. Also considering that the Bore of a 20 and 30 arent the same and many other issues that arise when attempting to make a 20/30. |

thanks for the photos mate they were great. now it definitely has 3 litre bottom end as i used my original block, its just the head i was a bit confused on but u could b right bout it being a n/a rb25 form the 32. not too worried bout it still makes ok power on 9 psi with more to come . cheers for your help and once again thanks for the photos. Fair enough, yeah bets are Definately on it being R32 RB25 head Looks perfect mate, love the paint and the kit. In my opinion all it needs is Calais tail lights Does the back of the cam covers have a raise in them? its hard to tell from the photo's as its so shiny. lol. If it does, then I think it is a 25 head... or at least 25 cam covers. haha No there is no raise. The covers and timing cover are 20 style but R32 RB25 had the same covers if you will view the photo i posted earlier. |

Beautiful VL mate Glad you like my photos of your car. I was talking to 2 guys that were saying one of them built your engine and that it was an RB25DET. Are you sure its a 30 at all? as the timing belt covers meet up which isn't normal as the 30 puts a gap of about 30mm(iirc) between them. Also if it is a hybrid 30 i would be leaning towards your head being a non-VCT RB25DE head out of an R32 GTS25 as it is a lot similar to an RB20 as opposed to an RB25 and retains the same cam and timing belt covers as can be seen here: . Also considering that the Bore of a 20 and 30 arent the same and many other issues that arise when attempting to make a 20/30. Ding Ding Ding! It will be an RB25DE Head. However I would be checking your block and making sure the engine number starts with RB30xxxxxxx.... |
