please help

Hi, i recommend you look at the details about "Family Hack" under the "Hot Micra" section.

This information may answer your question. "Family Hack" seems to have a similar turbo to the one you have ?.

If its a T25G sell it...

You will need an actuator rated at 6psi for that.

You will also need an intercooler for that boost on stock compression

Aaron is right though, do a search and you'll find most answers. Mine's getting on the road in a few days so I'm going to do a write up

ok thanks.

Hi simply mighty...I would like to understand more on your statement...

If its a T25G sell it...

You will also need an intercooler for that boost on stock compression

What is a actuator? actuator rated at 6psi means what?? SOrry as I am trying to understand more. Btw, what is the difference between T25 and T25???

tks

 

[CMF_Sean]

The actuator is essentially a pressure switch

The actuator is the cylindrical unit attached to the compressor housing with an actuator rod going to the turbine housing.

The actuator has a pre-set spring inside it that compresses under a certain PSI. The actuator is connected to the intake via vacuum hose, and this is where it gets its pressure reading from. When the pressure from the intake reaches the springs compression load, the actuator rod moves a flap on the inside of the exhaust housing which diverts gases straight to the exhaust instead of through the turbine. If too little pressure is made, then the flap closes. Its all goverened by pressure.

The reason I say 'sell it if its a T25G' is because the T25G is too big and laggy for such a small capacity engine. The turbo takes long to spool and makes the same power in the end as a T25.

A perfect turbo for the CG13DE would have to be the GT25, which is in essence a ball bearing variant of the T25, albeit with different trim angles on the compressor side though.

Hi Sean...thks a thousand for your detailed explaination. It certainly helps to clear up my queries. I would like to check if TD04 is a suitable turbo for our March?

 

[CMF_Sean]

A TD04 is definately <I>NOT</I> suited for a Micra

Bwahahah thats wayy too big!

No, they're the T25-28 kind of sized ones off the WRXs from memory. Not a T04 or T4 huge garratt etc.

I think they would be similar to a T28 and probably work ok.
Same with the other ones off the other Subaru's, i.e. the Forester turbos. I just forget the model numbers.

 

[CMF_evade]

Yer TD04's aint that big, besides the weird flanges and stuff it would probably be ok..wouldnt be hard to come by either i reckon.

hey don't knock the T25g it goes alright ahaha...

 

[cisco]

I think a T25G would be found out to be even better with higher boost levels. It doesn't really get much of a chance to use its full potential under 10psi etc.

Prob pretty similar to a T28.

I'll get to find out how laggy my new setup is soon.
I'm hoping it will be allright. Fingers crossed.

 

[CMF_Sean]

Ahh I was thinking of a T04...

My bad, are the TD04's BB or not?

Sean

 

[cisco]

How's the new car going mate?

 

[CMF_Sean]

Good mate,

Respray and 5% tint all round (except windscreen) soon... Followed perhaps by a VIP style quad exhaust just to get the nice rumble... VIP style bodykit? Still deciding on that one

Sean

 

[CMF_evade]

lol make sure they stick out like 1ft from the rear bumper too vip style

 

[CMF_jaxx]

vip bodykit? any pics/links

Would like to check what is a suitable intercooler to be used on our k11. Space seems to be a problem....Would like to check if subaru forester intercooler is suitable (seems like it is top mounted). How about Mitsubish Galant intercooler used for VR4? Pls offer your valuable advice...thanks

 

[CMF_evade]

i was looking at a VR4 intercooler at one stage..wouldn't be too bad an option i think

you can use any intercooler really its up to you ..as long as you can fit it and have piping made up.

 

[CMF_Tony]

I don't no about space but, Vr4 intercooler has very good flow capabilities if it's a jap spec.

The Australian spec ones where crap..
