Just a quick question. I have seen on prevoius topics some ideas for increased performance from the 2.8D Hilux 3L, being 2.5" exhaust and extractors and K&N air filter. Not to mention a Turbo. My question is will just a 2.5" exhaust and K&N filter do the trick or does the 2.5" exhaust need the extractors. Also if I fit a 2.5" exhaust now and fit a turbo later will I have to change the exhaust again?
Any comment would be greatly appreciated.

If you want your motor to last, use either Toyota air filter elements, or fit a Donaldson type aircleaner.
On my 2H, I recently fitted extractors (off eBay, $50) and 2.5" exhaust.
This mod made noticeable gains in power delivery. I do not think a larger bore exhaust on its own would make an appreciable difference.
exhaust and air filter will make a difference, extractors make it very noticable, and different brand extractors make different improvements. the exhaust will be fine with a turbo. BUT when you fit the turbo the exhaust will have to be changed to fit the turbo so you may aswell fit 3 inch new exhaust..... lol, but 2.5 will be fine.
turbos are nice but i'd rather be blown
Ring AXT or DTS Turbochargers.....you WILL NOT have to change your exhaust to 3".DTS turbo-chargers are dynoed with best power delivery tests coming from a 2 1/2",this is what they recommend for best results. Yes,the turbo has a 3" dump pipe off the back of it,but an exhaust shop will reluce the size to meet 2 1/2" no worries.I did exactly this just recently....had extractors & 2 1/2" exhaust,but needed more poke,so I bolted on a blow-dryer 
Still have extractors sitting in garage,PM me if you want em!

I agree on the exhaust, but why purchase the extractors? they won't be used for the turbo...sambo2222 wrote:thanks heaps for all your help everyone. I think I will do the 2.5" exhaust and extractors for starters and then when i get approval from the minister for war and finance (Wife) i will go the turbo.
