true longer intake runners would be good for a NA engine, but with a turbo it's not as important.

now i just have to finish my suspension upgrades so i can think about a turbo :)

Yeah I understand that ronald is talking about inlet tube lengths thats why I was informing ronald that the post is about the exhaust tube lengths!!!!! ie Ronald's post has no relevence to this thread (sorry no offence Ronald or Timo)

No Ronald is talking about the inlet pipes, where as the original post is about the exhaust.

Ronald i think the original post is refering to length of the middle two exhaust tubes as opposed to the length of the exhaust tubes coming from cylinders 1 and 4

So equal length would be ideal, but it's not the end of the world.


different pipe lenghts will alter the torque curve of the engine.
the longer the pipe distance from carby to inlet valve the higher the torque, but u sacrafice response and high rev power.
shorter pipe is the opposite. so having a mix of short and long pipes shouldnt really matter, as u dont have the block o-ringed so you wont be giving it to much psi or to much flogging

T25 should have no trouble doing that proably would get full boost befor 3000rpm proably even at 15 psi.

Im sure kegs is running a t25 just ask him how it goes or did I wonder how its going now if his engine is back togeather now???? anyone know???

A15's aren't rev happy give me a 3000 - 6000 powerband and i'll be happy. Boost levels, no more than 20 psi tops - that way i can bleed off excess. maybe 12 psi tops since 10 is a safe level without o-ringing the block.

Your water temp will run hotter unless like you said have a massive radiator but IMO just the oil cooled turbos are better because there is more room for oil and the oil cools and lubes your bearings the water only goes around the outside and there is less piping like DAT12S said.

I believe a T25 would be the smalest you could go without restricting top end performance just depends howmuch boost you run i supose

what ran hotter? the coolant temp?
You probably needed a bigger radiator to deal with the increased power anyways.
