hey ppl

I have a rb20 in a vs commodore just wonding a u thing of it

there are alot of ppl dong turbo conversions to the commo's now. i suppose its a different idea, but if it were me, id most likely just put my $ towards a turbo car, instead of puting all the money into a conversion like that. but each to there own.

Hmmm, I would have thought that having such a low capacity engine would be a bad idea in anything other than an early model Commdore due to the lack of torque. RB25 would be a better solution, but personally I would have gone the 1JZ or 2JZ. 1JZ halfcuts are still pretty cheap too I believe.

Good on you for being different though.

The ecotec V6 in the VS model produced 147kw at the fly

The Silver top Rb20det is 164kw at the fly....

However the torque would be better in the V6 as it had a storter stroke and larger bore....

Either way you can buy a million parts to make an rb20 better but you cannot just pick up a catalogue for a buick V6....

Nice job.... I have wired a VB with an rb26 and a Vk with an rb25 in the past few years and it was not easy at all... But plenty on fun...

i know a guy who has twin turboed his VN V6 executive motor, has GTR turbo's on it running a wolf computer. but he's lost his licence for like 2 years so its been of the road. also there is another guy getting round up here with a 1jz conversion in a vn commo, goes fairly well.

mate jus swapped his riced out lancer for a twin turboed vr commo ute.runs 300zx turbos and haltech and alledged internals.

supposed to have 340hp at the treads but runs like a dog atm. with a tune and a bit of sorting it may be alright. would have thought the 300zx turbos (t25??) would have been a bit small for a 3.8L. it makes 10psi at like 2000rpm.

that would be a weapon of a bimmer overev1

well gtr turbo's are only T28's, like the ones on my mates, its alot of stuffing round in the end, i told my mate with the amount of money hes spent on his vn he coulda had a 12 sec car easy, and done a RB26 conversion to it, he's kicking him self about it now, but thats what u get for trying to flog a dead horse i guess.

There are buick V6s that came stock turbo... Not here but in the states. They run some insane times considering the lard arse cars they are in. I really dont understand why more people dont do them over here. Commos make awesome sleepers tho.

A VN-VS commo weighs about the same as a cefiro or skyline sedan anyway, I dont see the problem.

Out of interest tho, whats the fuel economy like now? Better or worse.

You can swap just about anything within reason...

I have seen an rb26dett in a VY Commodore... So thats in the same boat....

      Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
