turboing a k series...

[mr bmw]

rit-e-o

after a few other plans hav been taken off the drawing board, i have decided to turbo a 5k carb to go in my starlet.

now im wanting a basic set up just to give it a bit more go juice.

how much effort is this going to involve

ie. what type of turbo, how much internal work am i going to need to do, where will i get the manifold etc etc etc

cheers for any help

Easiest way is a suck thru setup and about 5-6psi. And don't forget to change the jets in the carb to cope.

I've been in a 4K turbo starlet, its reasonably nippy, but still nothing flash. I believe a n/a worked 4K would be faster, but less driveable.

From memory, you're looking at custom exhaust manifold, he had a T2 turbo (off an ET turbo pulsar), and an SU carb off an older euro something(Vauxhall?). Didn't idle too well, but went hard, I remember he had issues keeping it cool with the factory radiator, something to take into consideration. And blowing headgaskets on a weekly basis!

Driveline.. it was a 5spd, factory diff. Held up fine.

Hope that helps.

im considering doing the same thing. im looking at building a turbo 5k to chuck in an old starlet for a thrash/rally car

looking at a set of solex carbs, and using the ct20 i have spare. will have to fabricate custom manifolds etc for it

Cant have an intercooler on suck through, but you need a sealed carby for blow through. IC might not bother you, would probably be an easier way to go. I've got a mate setting up a turbo 5k to drop into a KE20, bits still being cleaned up, balanced etc. Plan is to run a TD04, looks like not a bad size for the engine. Depends how high you want to rev it, where you want your power and everything else as far as what turbo you put on it

If you want some low compression pistons and stronger rods use the 1GGTE piston and rods as they fit straight in with no mods required.

When we did it years ago we had to build a sealed box to hold the carb in and keep it pressurised as it kept blowing the seals out of the carb.

just watched a video i made at the tauranga burnouts a lil while ago and there is a turbo 2k? starlet with a nice big intercooler hanging out the front and from the looks he DEFINATLY had over heating problems!!!!!
it seemed to have a box type of thing on top of the carb???
i am really confused now!

mite sit in the corner and cry for a while until i forget everything and start thinking again.

anymore info would be really really helpful!!

well intercooler would mean it would have been blow through, therefore th box could have been like a plenum sort of? say if he had twin carbs, it could have evenly distributed the air through both. and a 2k? why would he bother wen everything would b a straight bolt onto a 4k or a 5k.. or even a 7k?

[dattohoe]

thinking of doing this myself whats the deal with the box around the carb? is it just on entry into the carb? or are there other seals that will blow out the sides of the carb say?

[kingcorolla]

one thing i dont get, is the blow through setup, i initially thought this was not possible.
Reason being, I thought as soon as there is above atmosspheric ( boost) through the carb, it totally contradicts the carbs function. Meaning causing a high pressure eliminates venturi effect, therefore no fuel..? Because its LOW pressure which draws the fuel?
grrr i need to know!


but a "suck through" is completely understandable

.....rising rate......

[YeMs]

.....rising rate......

i am assuming u mean rising rate pressure regulator? how is it possible, considering carbs use a fuel bowl, which are $&#$% all pressure. i have seen carburetor'd cars using a fuel pressure regulator, but its not a rising rate type.

ok... confused/excited at the same time.....*giggles like excited child*
7K tehehehehe please explain more....... hav noever heard of these things..... how many cc, how much, where from?????
cheers mike

Good luck finding a 7k, and if you do its not likely to be cheap. Came in late model vans in carb and efi form from 97-98. 1800cc but not a very revvy motor due to the longer stroke and presumably a taller deck height to match.

solves all problems then.
4 or 5k it is!!!

still considering making a hellishly high revving n/a just for easier insurance!!
