what turbo you running and what did you do to the bottom end, what car are you running in
are you running 2 bar overboost and 1.5 held

evo8 tdo5hr turbo, std p4 bottom end ie std block with oil squirters, steel rods and "low comp" i've done it by a fat head gasket on this build. next build probably std gasket low comp pistons.
p4 runs 1.8 over and 1.6held which is what mind does yes smile

whats a evo8tdo5hr i assume its from an evo mounted to a let manifold, are you running external wastegate
what oil squirters you running and who built the bottom end

Me and my friends black and decker did the squirters, they're just 1.7td ones, they have a fairly large hole in them but they seem to do the job, i run a thick race oil anyway.
yes its a mitsubishi EVO8 turbo, model TD05HR, its on an EVO manifold on a let head flange.. runs internal wastegate so just on an actuator..

got any pics of where these oil squirters are fitted what exactly is involved, where did you get the let flange from is it the one which sits on a standard kkk16

flange can be bought on ebay, i cut mine off a redtop downpipe though.

not sure i have any pics. you just drill through the mains (and the shell in the same place)... there is a how to guide on here somewhere.. search the usefull links thread in technical.. i can't think if there are pictures showing the angles or not. that was done by grinding the block rather than drilling the shell.

i have the 4 injector phs4 on mine, with vxr injectors i ran 4bar fp on 2bar boost. think they were close to maxing out. since changing to msd's i now run 2.5bar and fuelling is good. if i run over 3 bar it hesistates/misses @4000rpm. must be dumping alot of fuel in! if you do buy msd's get them from the states as said.there all over ebay! Thumbs Up

also think the angle for squirters is 7 and 13 degrees iirc. easy money on a milling machine. best way impo is to put a peice of bar in the chuck and use it for a guide to the tops of the bores obviously you need to think about were it will be when the chuck is posistioned over the bearing cap and compensate to suit ( the bar wont be central when mocking it up, it will be x distance to the side of the bore as when you move the bed the posistion will change)
there are 2 angles so the squirters point to the front of the pistons were they are hotest, watch out for the trigger wheel on the crank also on no.1 . may be a few pics of it somewhere in my progress thread if you wona look. spread out all over it tho as i never do a full job in 1 sitting lol beer

i used eds phase 4 on my let
i use them with bosch greens(440cc) @3bar and walbro fuel pump
i am running at 17 psi and i melted pistons

let · vauxsport.com Joined: 05 May 2009 Posts: 62

emret so what fuel pressure was you suppose to be running with the greens or did you change to different injectors

let · vauxsport.com Joined: 05 May 2009 Posts: 62

so have you sold your phase 4
are you running evo 5 with standard injectors at 4.5 bar, what should the afr read ie ideal are your figures showing weak mixture

emret · vauxsport.com Joined: 02 Mar 2008 Posts: 89

yes i removed my eds phase 4 chips
first i install evo5 chips with 440cc @3 bar
my car cuts at 5500rpm(afr goes to 10,00 my wideband cant read smile

so i remove 440cc and use let injectors @4,5 bar fuel pressure
now i am happy smile

my car never cuts and goes well i am running at 15 psi cont 20psi overboost

11,3 and 11,5 is very good for phase 3 let

let · vauxsport.com Joined: 05 May 2009 Posts: 62

do you still have te phase 4 chips do you just fit them straight into an ecu or is map sensor upgrade required

emret · vauxsport.com Joined: 02 Mar 2008 Posts: 89

now we are using phase4 chips on vectra turbo we are going to upgrade turbo(gt2871)
we install 550cc on vectra with phase 4 chips
now still vectra running with k16
the afr is good
when full throtle cur cuts but after gt28 it will be perfect

for map sensör we are using 3 bar greedy map sensor and emanage ultimate(we cut map sensor pin2 on ecu and connect 3 bar greedy map sensor)

sorry for my bad english.

do you know anyone selling a phase 4 ecu or chips can my phase 3.5 ecu be upgraded if s ow much
where did you get byou map sensor from do you mean greddy as in the japanese tuning firm

emret · vauxsport.com Joined: 02 Mar 2008 Posts: 89

you can use every map sensor
cut pin 2 ecu map sensor and connect the new map sensor signal
we bougth eds phase 4 chips from ebay.co.uk

let · vauxsport.com Joined: 05 May 2009 Posts: 62

emret what did you look for on ebay as i cant find any
do you have any pics of where and what needs to be cut on the map sensor, which is pin 2 and does the map sensor just plug in, sorry what do you mean by every map sensor

emret · vauxsport.com Joined: 02 Mar 2008 Posts: 89

we buy phase 4 chips from france seller on ebay
on map sensor there are 3 pins
one is +
one is -
and the other is signal 0-5v
m2,7 map sensor is 200 kpa
if you want to change it buy 300 kpa sensor
firstly on motronic 2,7 cut map sensor pin2(signal pin) and wired it to 3 bar map sensor signal it works perfect

on this picture you can see
1.
2.signal pin
3.
i cant remember 1 and 3 but one is - and the other is 12v

this map you can use
if you use 4 bar map sensor ecu gives error
low voltage map sensor error.
