Sadly you have revived a "KE70MAN" thread. I don't think we have an appropriate emoticon to express my feelings

about the guy...

Nice engine bay there though

Blame darren not me haha trout slap!!

engine bay looks HEAPS better now, isn't full of charf like in this pic. I was driving it round for a little while with

absolutely no exhaust on it- just coming straight out the back of the turbo.

when i buy a new usb cable for my camera i'll get some pics up of the new engine looking engine bay.

it was all just done for shits and giggles really.

oh yeah, it was $400 in parts etc (out of that fuel pump was $97, and exhaust was $80 being the most expensive

parts) got 2 1g ct12's for free!!

but there was also around 100 hours of my own labour which was the big saver.

100hours x say $60 (average mechanics hourly rate) = way to much for a corolla.

If its a Turbo carby, you don't want much fuel pressure

bupbow, I'm gunna pull you up on that one.

blowthrough or drawthrough both actually need quite a bit of fuel pressure. blowthrough espeacially.

at the moment I am running about 12 psi straight into my needle and seat. the pump is a carter black which makes

12-14psi. at the moment i am restricted to about 10psi of boost, because if i go over that (or my fuel pressure drop for

some reason) then I run out of fuel!!! this is cause by there being more boost pressure than fuel pressure to the fuel

actually gets puch back along the fuel lines to the pump.

I'm actually just about to change my fuel setup. Its taken me a while to find a suitable fuel reg within my corolla

budget. what I have been looking for is a rising rate, adjustable reg suitable for carby turbo cars. these regs will let

you set base pressure from 3-15psi at idle and then 1:1 boost reference above that on boost. I couldn't use a normal

EFI malpassi etc as you cannot get the base pressure down far enough for the needle and seat to hold it. I'm just

going to use an s14 in tank pump out of a mates car.

this way I can run say 20psi if i wanted as the fuel pressure would jump to say 25psi, with a base pressure of 5psi.

sorry bassy,

carby is a 32/32 dtmr-a off a fiat 128 sport L. has a massive needle and seat (for this weber) out of a 4 litre falcon

weber, secondary jet in the primary, redrilled secondary jet. thats about all the mods to the carby. oh yeah its got no

choke flat either.

The whole idea about putting the carby in that box though way to have equal pressure on both side of it so that really

made boost modifying it not neccessary.

current pump is a carter black, 100gph @ 12-14psi with NO-REG!

in a couple of weeks the fuel system will consist of:

s14 in tank pump.

aeromotive AER-13204 carby turbo rising rate reg. 3-15psi base pressure. 1:1 boost referencing.

this reg will require me to setup up a return line to the tank.

Wow, should have said something like "don't bother buying a Bosch 040 pump because its overkill" but fair enough

mate

--------------------

Taz_Rx Post #26

Brappn or boostn

haha yeah an 040 deffinately would be an overkill, but you could use it. would just be a heaps more volume and

pressure for the reg to regulate.

short and narrow of my above post:

for a blowthrough carby turbo you always need more fuel pressure than boost pressure.

this is a pm i just sent to somebody, though i might aswell cut and paste it here to so the next time i get asked about

my setup the typing is already done!

Hey mate, I'm looking to do the turbo setup on the 4k shortly! Was wondering if you've got any other pics of the

setup on yours? Just wanna get a good iea of the setup ya got on there (visually - your posts are pretty

informative!). Thanks mate!

here a couple of early shot befor it was running. notice the absence of chaff from running it with no exhaust whats so

ever.

shows the carby in the bottom part of the box.

http://i23.photobucket.com/albums/b396/taz...uff/Picture.jpg

http://i23.photobucket.com/albums/b396/taz...tuff/rolla1.jpg

http://i23.photobucket.com/albums/b396/taz...tuff/rolla2.jpg

these are a few weeks after it was running after i finally got some exhaust on it.

theres the chaff!!

my massive turbo!! haha, atleast its made by toyota!

http://i23.photobucket.com/albums/b396/taz.../Picture015.jpg

the j-pipe on a ke70 manifold. ke35-55 etc have a 4-2-1 exhaust manifold (headers) and the ke70 ones are 4-1. had a

little water leak till it cooked itself shut.


all 2 foot of exhaust. just got the rest put on on monday.


water lines and bov.


oil send. $10 worth of fittings from enzed!!


my busted bov. hose blew off, bov hit the engine fan, busted holes in the that and broke 2/3 of the fan blades off!!


this end of the j-pipe is supported to take some whieght, but with a flex rubber mount as it still needs to move with

the engine.






7 of 10 1/11/2008 3:23 PM

the pic you would have already seen.


so just a quick run down on what was required, and some rough prices.

turbo - free (a mate has a 1ggtte celica who has blown 2 engine already, so he has 6 turbo, i'm already on my second.

turbo plumbing (exhaust manifold) - ke70 exhaust manifold $30 from a wrecker. but you already have one.

took a dummy j-pipe mad out of toilet rolls and lecky tape to midas. they bend it up for me but thought it wasn't right,

so i got it for free, but it did the job.

flanges for the j-pipe were cut off an on ke70 exhaust and i spent and hour cutting one out of the 1g manifold with an

angle grinder!! so they were free.

the 2 foot of exhaust cost me $80 cutom made. again at midas.

water lines were taken from the standard 1g setup. free again.

oil lines as mentioned above, were $10 from enzed for the send fittings. with the return, (this is really dodgy) I drilled

a hole in the sump, used the standard 1g oil return fitting that bolts onto the block and welded it over the hole in the

sump. did this still in the car, so there was oil fires and all shit while welding!! get this as high on the sump as

you can.

the 1g had bolt on oil fittings with steel lines, so all i did on the turbo end was bolt the fitting back on cut the metal

linesn and slip and clap hoses over them, keep your send oil line down in size to keep the pressure up!!

the drum that the carby is in is actually the box that hold the air filter inside it on a hilux, was $25 from a wrecker.

keepn it in the toyota family again! ! this was perfect for what i needed, as the top (now bottom) was shallow

enough for me to still be able to bolt the carby down, but high enough to run the fuel lines and excelerator cable

through the side. btw, it took a bit of modifying and r&d to get this right, the standard clips that hold the filter in won't

hold 1 boost, so it is sealed with threaded rods that run through the box (top to bottom) to squash it together. just got

wing nuts on top.

oh, obviously battery was relocated to the boot to made room for the turbo, i also ran all the wiring on this side of the

car down through the guard.

the hoses in the pics were only temperary, bottom ones an old radiator hole, standard mx6 bov, and the one with the

flex rings was off the hilux. (which was useless and kept splitting. cost free, free and free.

standard dizzy was locked, with cable ties!! with no vacuum or mech advance set on about 20 degrees befor at

idle. I did put an unlocked dizzy in it a one stage, and it blew headgaskets like there was no tomorrow. don't worry if

you do, if you know how to fix them (hardest bit is doing the tappets) it costs $67 to fix a k series head gasket - $44

for head machining, and $23 for the gasket (can you tell i've fixed a couple!. )

oh fuel system - this is the bit that took the most r&d to get right as i did everything the hard way and found out for

myself.

the original setup consited of my old carter green pump second had from my mazda (these are suppose to do 72gph

@ 4-6psi, IIRC) and a run of the mill adjustable fuel pressure reg (1-6psi) for $30, regged to about 5psi.

what happened with this is it would boost fine, and if you held it on boost for about 10 seconds it would just die in the

arse. basically what was happening was the 6+psi that the turbo made was greater than the fuel pressure being made

by the pump. this caused the fuel to be pushed back along the fuel lines backwards through the pump and back into

the tank. the 10 worth of fuel that I had was only what was left in the fuel bowl.

I fixed this problem by getting a carter black (100gph @ 12-14psi){i'm a fan of carter pumps, rather than say holleys,

as they are self priming and you don't have to put them below tank level.} and fucking off the reg (small weber needle

and seat will hold this) so that I had 12psi of fuel pressure vs my 6psi of boost pressure.

this setup works, but is not ideal, as the pump still get pressure pushing back on it and will no-doubt fuck the pump.

after about 6 months mine is starting to fluxuate a bit.

I am now running a boost controller switch at 10psi of boost, but can't go any higher as i will then have the same

boost pressure vs fuel pressure issues again.

this leads me to the new fuel system i am about to put in that i mention in the post. I'll use a s14 in tank pump

(located in the corolla tank so i don't have to use a surge tank.) with an adjustable rising rate fuel pressure reg

DESIGHNED FOR CARBY TURBO cars. I will set base pressure to about 5-6psi at idle (but can go higher as i know the

needle and seat will hold it) and then have a 1:1 boost reference from there so compat the boost pressure. so for

Apr 1 2006, 12:21 AM

example if I was to run 25psi, fuel pressure will jump from 5 to 30psi.

so theres just a quick run down!

if anyone has any q's, fire away!

specs???

Is that an SU hiding in there? or maybe a fuel pressure reg. i really can't tell from that angle, or does it have

some sort of EFI??

also is your exhaust manifold sorta like extracters that collect just befor the turbo?

and while were on exhausts, is that lttle pipe a screamer or does it plumb back in?

shits and giggles are great hay!
