Rb20 Det

[Roy]

The best thing about the new engine is knowing its 100% reliable at these power levels, with my old RB20 setup i always knew something would break sooner or later.

It turned out to be a track day in darwin at 35 ambient temps and some overboosting that killed my RB20.

Way i look at it no engine is ever 100% reliable, things can always fail, injectors clog, tips fall off spark plugs etc but i hear what you are saying.

You will find that an RB20 will make 200rwkws in its sleep, and will do so for years of driving. I have done a track day at Sandown on a 38deg C day makign 234rwkws and the thing didnt miss a beat. The kms on my RB20 in various states of tune and levels of boost has seen it make between 215-260rwkws since late 2004. They ARE perfectly reliable at 200rwkws as they are at 160rwkws. The same rulle applies, control coolant and oil temp, control detonation and there isnt a problem.

The same things that will kill a 200rwkw RB20 will kill your 200rwkws RB30.

As for the going past 200rwkws getting expensive. I agree, but not because of thigns liek brakes and suspension, but because you need injectors, AFM, good oil cooler etc. All R32 Skyline should have upgraded suspension by now, they are between 14-19 years old so expect owners to have tidied the car up with new shocks and springs and bushes before chasing power.

Re brakes, std brakes with good pads and thick rotors will handle the demands of a 200rwkw R32 without too much fuss. If you start running grippy tyres and +200rwkws then a larger rotor from a later model Skyline would help though.

All i ask the original poster is that they go for a ride in a decent R32 GTSt before they commit dollars to an RB25 upgrade. It sounds like money isnt growing on trees, and i think in such cases the money spent on the RB20 will always bag you a quicker car then simply converting to RB25 which will see you stuck with std turbo / ECU etc and makign 190-200rwks. It would be a good building block for future mods and big power, but if thats not in the picture then stick with upgrading the RB20.

Dont forget to check with your states requirements for engine transplants and engineering. Registering an RB25 in your car may be a few additional headaches come time to update your rego papers with the correct engine number

i personally think the amount of bullsh*t you go through upgrading to a bigger motor really means your comitting to at least another 2 or 3 years of 32 ownership which gives you plenty of time to sort a good allround setup out on a 25 or 30.

I do agree that you can get great results from the RB20 though and it has definitly been proven on this forum.

Also cubes i hear what your saying about my turbo size .82 would be great but i ended up just using a smaller one i already had, and yep she peaks at 5500-6000 i really thought the VCT would help it rev but it didn t do much for power just gave the torque curve another lump at least i can cruise round town in fifth saving juice now.

roy as for n othing being 100% reliable i guess thats true except for one 4AGEcorolla i used to drive....

ppl are always willing to nock the 20's but thats cos theyre comparing them to a 25/26 not just an engine on its own as far as it go's as a motor theyre pretty rock solid and love to rev I might get a 25 in my 32 one day but i think if i was going to id just buy a 34 lol
