Hi, am about to fit gtst valve springs to my R32 RB25de head, but before i bolt it down im fitting oil restrictors to the block. Can someone tell me if the RB25de head has hydraulic or solid lifters? Iv been looking around but havent found a straight yes or no answer. So any help would be awesome. Also what is the advantage of having solid lifters (eg the RB26 motors)
Cheers xsv_32 |

The RB25 VCT ( GTST ) springs will not fit as the exhaust is a different length to the intake - where as the R32 RB25DE are same length ( same as RB20 and RB26 ).

RB20DET and R32 RB25DE springs are the same.
The reason the RB25DE springs suck is because they are trying to control a larger valve with boost behind it. Which is going to result in float earlier than it otherwise would have in the rb20det. Drop a set of GTR springs in it. They can usually be picked up for ~100-150. If you can't get them for that price grab a set from Performance Springs in QLD for $280. Unless its a budget build I'd prefer to throw a decent set at the head for $280. -------------------- I use and recommend  |
