as above what wud be best? been told ya have to change oil more often if you use Siemens is this right?

 

Maybe I'm being thick but I don't think an oil change effects the Injectors?

As for which Injector, whats your spec and future plans mate, both could suit a T34 but neither might suit a T3!?

Post up some more info

 

Running a T34 on dark greens at the mo peaking at 1.9 bar and holding 1.5 bar,was wondering weather to change injectors and wind boost up a bit or go full hog and change turbo aswell to a T35 or T38 aswell as injectors as i dont want to be ringing neck out the turbo would be happy wi about 380bhp tbh

 

What housing have you got on the T34?

For a nice 380bhp I'd go T34.63 with some Siemens 55lb Blacks

A T38 would be plenty for a solid 400bhp if you want it, I think a T35 is much the same as a T34 is it not?

 

it all depends on the map, use quailty software from stu, and you wont have any borewash issues at all,
mine runs 83lb siemens and is superb idles less than 1%co, and the 83s are double the size of greys.

 

sounds like whoever gave you that oil change info needs to change tuners btw

 

nothing wrong with greys on a T3

 

I didn't say there was, I said it might not suit his application as there was no info on the original post!

 

Agreed, what a fooking statement to make.

 

nothing wrong with it at all but completey pointless when you have 311bhp

 

Glad I wasn't being a total div when I said that in my first post then!

Captain500, Who told you that about the oil/injectors etc?

 

not pontless at all if you happen to have some laying around at the time

 

dan,any injector size can make a difference to oil.....surely you know how?

its no fault of the injectors btw

 

I should imagine the oil comment is because of the over fuelling thoughts..... sounds like someone has been speaking to the wrong people, surprises me how many people think borewash is ok if you change the oil more often

 

he may have been right 15years ago, i remember when greys were not classed as road legal, cost they wouldnt even make it down to 3.5%

 

Didnt think it was right about the oil to be honest was just asking, the turbo is on .48 housing. Wud a be able to get 380 out the T34 wivout ringing its neck or wud it be wise just to change turbo

 

All depends on who you talk to on that one mate!

IMO a T34.63 will do 380bhp with relative ease.

 

Is it correct that the siemens have a better/finer spray pattern than the bosch greys?

 

Dont want the car to be laggy which a heard .63 housings will do,wud prefer to keep the .48 housing tbh

 

it will do it, but it wont be reliable thats the point people make!

if you consider a turbo a service item then go for it. personally i'd spend a few quid more and have some reliability

buy cheap, buy twice.

 

i made 370bhp on a .48, on stus 55lb siemens kit, veryvery good.

turbos dont like the 36psi needed to make that power though.

.63 would be the better option

 

a.63 would be reliable at 380

 

Just fitted a .63 housing to mine from a .48 and prefer the .63 much more. Not too laggy at all.
Although I must get it set up and the boost adjusted properly as currently its boosting 2.4 bar

 

I thought that too when i changed from .63 housing from a .48.

 

All this talk of the .63 housing making it very laggy is utter nonsense.

 

In the october edition of FAST FORD, there was a good turbo feature, from CR Turbo's.
The guy at CR Turbo's used to run a 2wd sapph with a T34 and .48 turbine housing, for a solid reliable 380bhp, without undue wear, usual 360 bearing etc, think he knows about turbo's.
tabetha

 

.......so true....it's the set up that counts......

 

greys can do in excess of 60lb's - they're an odd injector.

 

So how much would a .63 housing cost?

 

about £300 new,£100iish secondhand if you can find one

 

urm hello!!!what about a .55!not as laggy as will do 380bhp!


i hope lol!

 

I found siemens run alot better than greys and if you run a t38 then youve got plenty of fuel.

 

if that were the case people wouldnt blow them up all the time...



...and they do

 

not on a .63 at 380 they dont....

.48 will last around 30k miles at 370 bhp, which is around 36psi, i did two in my time on that spec around 60k miles, i dont really even consider that unreliable tbh

a .63 will make 380bhp+ at 32psi, and will last for years.

all engine spec dependant obviously, turbos genearaly have a shorter life span the higher the boost level

 

I run greys and a T38 on my 4x4 saph and I got no complaints with how it runs!

Runs just as smooth as it did on dark greens!

 

agreed lost count in how many threads of why is my turbo bolloxed and its only 6 months old
