dual fuel RB30 - wanting to set up turbo kit

[Matty 31]

Hey guys

need an opinion - lookin to get a turbo and manifold for my RB30 (until i can afford to do my RB20DET+5spd conversion). In regards to mods i want to keep it reasonably stock for insurance purposes (so they dont slug me too bad). ive already got a k&n pod , but my problem lies with the dual fuel setup. the gas reg sits halfway up the intake pipe. if i installed a turbo kit, i'd probably end up blowin gas into the turbo, thru the intercooler then in, which in my mind doesnt seem that safe or reliable.

What reccomendations do you make?

Basically i want to know at this point

1. will the standard internals (compression ratio included) cope with a reasonably stock turbo kit (basically pinchin a kit from a mate's VL Turbo)?

2. will i need to chance the ECU?

3. I need to keep gas/petrol. what way can i get around the reg problem (cos i cant move it over the other side of the engine bay as its got limited movement to where it is now)?

yes.. the 9.0:1 CR is fairly boost acceptable with proper RON fuel. I mean the RB25DET is 8.5:1 anyhow. The VLT is something silly like 7.x:1 which is bit low if you ask me -- they just made it like that to run off our shit aussie fuel circa 1987 and hot aussie conditions and ancient turbos.

The general recommendation is to not wind the boost up too much past 8psi.. and run a cooler. Personally I think you can probably wind it up a bit more than that with a decent cooler and maybe utilising an S-AFC, but I'll have to test that one out.

You should be able to get 130-150rwkw that way depending on the turbo you go for. For my r31 I'm going for a RB25DET turbo, and got most of the intake setup from an R32 (cross over pipe, intercooler and piping). I just need to grab the injectors and ECU and should be ready to go soon.

Change the ECU to a VLT one..you'll need it to run the larger injectors (which you'll also need to install) and turbo anyhow.. although with the gas ... hmm

Don't ask me about gas 'cause i know nothing about gas
