RB25DET into VL Commodore

[VL25]

I was thinking about fitting a RB25DET into a VL Commodore.

My plan in the future is to have it running in the 12 second zone, at least with slicks.

I was wondering if there was anything to look for in these engines and also how easy it would be to get running in the 12's second zone? (computer, Turbo, injectors and so on)

Thanks.

i have a friend with a r31 with a similar kind of idea. He kept his 3ltr bottom end and just went to a rb25 head, he did internals, turbo, cooler, computer and all the other normal stuff and his car makes 477hp at 14psi, and they told him depending on tyres and stuff his engine would be good for 11's, dunno how true that is but his car is pretty fast

My future Son-in-law has embarked on the RB30/RB25DET combo with his Calais Turbo.

He was after a job for $5000 to go well.

After twice that amount it still isn't finished.

Will post any info that may be relevant and watch this thread for ideas etc.

I done this conversion into a VR and with standard Computer, Turbo and motor it done 12.7@108mph. Mods where fmic, full zorst, pump, surge tank and a fuel controller.

P.S. It made 290@rears

I've seen a VL with RB20 get a 12.9

I don't think he had many mods to it.

Mates R31 with RB30ET, T3/T4 Hybrid, FMIC, modified inlet with throttle body relocated to the 'forwards' position, R32 5 speed, etc produces 170rwkw. He's got a RB25DET head and a T04E ready to go in, estimated to produce 230+ rwkw.

The RB30 and RB25 are physically the same block, all you really have to watch is the sump as the RB25 obviously comes with a sump to fit the Skyline so you'll have to use the RB30 sump that came with the VL.

I have previously seen RB26DETT fitted to VLs and what they had to do was to make a minor modification to the sump and the oil pick-up for clearance.

Good luck with this conversion as I too am interested in this mod for my VL. I want to put the RB25DET from my series II R33 into my VL and then get a RB26DETT for the '33. A bit of swapping around but it's all worth it. Imagine, a VL with a RB25 and a R33 GTST with a RB26 ! I'll let you guys know the results.
