2.7 Turbo project

[blingsta]

for some strange reason, all the cabbies ive had, the oil filters have always faced forward??

what are you meaning m8????the open end/threaded or flat end....i think they all point rearwards??hmn maybe wrong?

[blingsta]

the threaded end closest to bulk head.. anyway i dont want to mess or confuse the thread !!

[m-dtech]

that manifold looks good, any issues with steering columns ??

[chu346]

Shouldn't be, the turbo should sit on top of the manifold.

Shouldn't be, the turbo should sit on top of the manifold.

The ONLY part of the setup that will come anywhere near the steering is the downpipes.

Unless you go up and over like Graham and under the passenger side, gotta say that's gonna heat a hell of a lot of stuff tho.

[chu346]

Few more questions:
1. How much power are M30 yellow injectors good for?
2. How do I go about boost control? as I want to be doing about 4-5psi to begin with.

More Q's to follow.

1. Prob 230/240bhp at a higher fuel pressure but no more really. 30lb's are good for nealry 400bhp on a m30 and 42lb are good for over 500bhp on a M20.

2. Either get a wastegate set to the right psi or a manual controller or add a solonoid and control via MS.

HTH,Mark.

Agreed, that would be a mofo to wrap

[chu346]

Another Q, how do I get my cossie turbo with internal wastegate to operate at 5 psi?

[gcorky]

different actuator.........?

[Ant]

release some pre-load on the rod Chu.

righty tighty, lefty loosey

[chu346]

This wastegate business confuses me

Hi all been a while without connection, chu the cam might not match the turbo your using very well because of the increased overlap you have on a NA cam and increased backpressure from the turbo your using so it might work out better with a stock cam and sell the other one. NA cams can work ok but with bigger turbos. I might be wrong as this is just what I read, not fact and it might not be the case with low boost your running, thought id just try and explain why others mentioned it. Im sure someone else can explain exactly what happens when you have too much overlap for your backpressure because I dont really know but I know when I had my cam ground its was like a 272 NA cam but with abit less overlap. Anyway good luck with project dude. lots of pics to come from me soon

In a high overlap high backpressure situation you are getting seriously contaminated intake charges,
as exhaust is coming back into the engine for a longer period of time then with a stock cam ,

backpressure = slower "scavenging" by the turbo = lower efficiency of the setup
high overlap = longer intake time = more air in cylenders

put the two together and you get even worse results than with just high backpressure,
the combustion has less 02 in it and the power drops even further and the turbo looses speed, and the exhaust
also heats up the intake charge and you get more prone to knocking, as your ems isnԚ´t measuring the temp of the air in the cylender you canԚ´t have the ems react to the problem,


get a bigger turbo and the high overlap starts to benefit at a fast rate,
