So every week i come on the forums and see a differant "how do i turbo my k motor?" and the reply always seems to be "use the search function"
however there really are no walkthroughs (bar one, but it isnt very good, and is very negative towards the idea of a turbo K motor.
So, here are some quick walkthroughs on turbo setups for K series motors.
*All of the following ideas will be costly, and wont result in huge power figures*
*The first thing to keep in mind about a turbo is that your K series motor (if stock) will probably not handle any amount of boost you throw at it. your head gasket will be the first to go, to overcome this you can either run 2 copper gaskets or a metal gasket, however then you put strain on your pistons and rods etc, (in short lots of things with have to be replaced on a regular basis unless you put money into the right parts)
Onto the setups:
1: The first and most obvious way to turbo a k series is using the conventional method of a turbo forcing boost directly into the pots, then injecting fuel via injectors then igniting, lthe same as the following engines (ie. RB20DET (skylines) CA18DET, SR20DET (silvias) 1JZGTE (cressidas etc)
to do this your going to need the following:
exhaust manifold that will fit to the dump pipe of your turbo
the turbo itself
4K-E inlet manifold with injectors
a blowoff valve with boost regulator
a wastegate
maybe even an intercooler
then you need to think about oil lines etc etc.
ive never actually seen anyone with this setup, regardless of lots of people on these forums telling me stories.
due to the latter i cannot comment on power increase etc.
2: Option two is a "blow through" setup, this is where you set up a turbo as usual however insted of using a fuel injected system you vent the boost to the top of your carby, this can be tricky because often boost is leaked from seals in the carby and conection. its recomended you make an air tight box from steel, or a materiel alike, then house the carby inside, then you can eliminate some of the places that will leak boost.
however you can buy an inlet manifold designed specifically for this, i forget the name however.
3: The third option is "suck through". Again same set up as normal however you need to find/make a manifold to link "out" or bottom side of your carby to the intake of the turbo.
however you will have to buy a turbo thats capable of passing fuel, i forget which ones can, i think from memory its the ceramic wheel ones. (please correct me if wrong)
so from now on, no of us should have to see any more new topics asking how to turbo thier k motor.
just ask question in here.
ps i can't be arsed proof reading this shit, so expect mistakes.
