hey i'm running a na rb30 and i was goin to weld up the injector holes on the inlet manifold. are running a standard t3 turbo and a decent size cooler. the car already has a gas tank in it and gas lines. what will i need to get to run strait gas turbo. here are my qu's will i be able to use the existing stndard converter? do i leave the standard throttle body and use a flow through ring? if not what is best to use? where do i get these? how much?

You will be able to use the existing converter if you are able to run a balance line to it, BUT it may max out at a pretty low power level (GRA high flow B2 converters are considered a good choice) Venturi rings dont like boost and are very poor at providing good mixtures and adjustability, don't know of anyone running boost through anything but the GRA throttles EBAY and the trading post are good cheap options if you have the time otherwise go direct to http://www.gasresearch.com.au/

have a search thru the gas section here mate ull find all the info you need theres a pretty tried and proved formula that most ppl are using and its not rocket science once you do a bit of research. let us know how you go anyway! Some original photos have not been recovered yet.

thanks guys all this info has been very helpfull and i'm now peicing it all together. can you tell me is there different size gra throttle boddies. and do the b2 converters come in different sizes. if so which size is best suited for an rb30turbo

if it was as easy as it seems id have my VLT on gas by now, or would have had one of my previous ones on gas, always thought about it but lack of tuners/information and wasnt sure what mods most ppl use gas wise, and the rough cost to put a standard ish VLT on it, FMIC, exhaust, 10psi or so im more than happy if i can get it running nice on gas for a daily! Bolby u know more than me when it comes to gas the only gas car i ever owned was my work ute when i was a courier, lol, throw some tips this way, u reckon its pretty easily done ill give it a shot as the VLT will be the daily for the misses would be laughin on gas! Some original photos have not been recovered yet.

with the electrical things aside fitting a gas system is pretty simple. fit tank, run gas lines, setup lockoff, converter and t/b and send it to a gas shop to have the electrical work done and get the compliance done. not that much different to fitting a petrol system. obviously theres more to it than that, but its a pretty basic system. unfortunately to pay someone to do the whole thing ur looking at around $3k depending how much power u want the setup to handle. theres no doubt a VLT will run nice enough on gas to have as a daily. would barely notice the difference. and the t/b come in a few sizes, 400cfm, 440cfm, 480cfm and 510cfm.

and the t/b come in a few sizes, 400cfm, 440cfm, 480cfm and 510cfm which size is best suited fo a vl turbo set up?

any one of the them apparently lol i know of a few using the 400, GAS747 uses the 440cfm and ive got the 480 cfm... i dont think it makes as big a difference in forced induction as it would an n/a engine. most V8s will run a 400cfm as well as a 440 or 480 cfm t/b, but with forced induction a single is fine. its things like converters and twin outlet gas tank that will have a bigger impact on the amount of power u can make a single converter single gas line system will be limited to around 220rwkw
