LoL, admittedly that came out a bit strong, scuze
The below is essentially the crux of what I was passionate about...
$2.10/L - is really only a 25% increase, id pay that with a smile haha.
You didn't quote your current ability, so i assumed it based on your Q. A forum based mostly on modifications to Skyline skimps on the basic stuff, which can send a person backwards $$ very quickly... I know someone there now
Without getting into a debate regarding the legitimacy of info available in public forums, simply put, its about numbers. The viability weighting of info should be based on a singular persons apparent experience / knowledge, or simply the repeating of the same info by multiple sources.
On the other topic, without offending ppl, IMO theres a massive difference between a normal career mechanic VS an experienced mechanic with a passion (and business) for highly modified cars. Advising, piecing together, tuning and then putting your word on a particular customers 10- 11sec setup IS more then worthy of the 'technician" moniker.
Mind my English and bar all the jibba jabba, I reckon as long your passionate and skilled enough not to sweat over loosing an engine or entire car while tinkering - theres nothing to fear
