have you guys ever thought about turboing your non-turbo motors.... it really is cheap and majorly efficient... all you need is the factory turbo... oil lines/water lines(to the turbo) manifold and intercooler... and turbo computer and injectors....
my mate had a non-turbo r32 that he got CHEAP... and then he bought an blown up turbo motor for two hundred dollars... it was a complete motor that had internal damage.... he swapped all the turbo bits onto the non-turbo and it runs like a champ...
it has all the factory oil feeds and water feeds already in the block... just pull the bungs out and put the lines in place... and this skyline has been at dorift events in brisbane, drag raced and just generally abused without a single hiccup.... we just keep in with standard boost and it runs all day with no pinging or anything...
after the success of that build we Na to turboed my silvia... and it is a little rocket... it owes me about $700 for the conversion but is no where near as simple as the RB to turbo conversions..... you have to make custom oil lines and water lines... and is generally a little bit of a headache... although after doing one I could do another one in a day...
just if you have a Non turbo Skyline... and just want boost... not a monster... just a standard turbo'd skyline consider this an option it really works... we have the cars to prove it....
just go to the wastelands, to squizzmobiles III and ask any of those guys... there are some cool toys cruising around Centeral Queensland and most of them aren't as convensional as down south... we don't have access to loads of performance shops and if we do they are to dear... so we build our own toys....
sometimes you just have to think outside the box... and don't let anyone tell you it isn't possible.....
