Into the account of work ECU you are right, but there were cases when ignition was not rolled away.

Thats not good!

Anybody here want to sell their RHF4 turbo? I am looking for a secondhand one. Not much YRV Turbos here.

[Volvarine]

I got a Mitsubishi TD04-15G turbo from a Volvo. Is this turbo to big for the YRV?

[URAN]

What do you mean "too big"? Size to fit (dimensions)? Size to blow (productivity)?

[Volvarine]

Size to blow (productivity).

I think it`s not best choice, but acceptable.


How are you going to adjust fuel system to put more fuel, according to increased amount of air? You need to keep with A/F ratio. If you simply put big turbo and let it boost up to 1 bar, you will got excess of air, exhaust temperature will raise fast and overheat your engine...

I also considered TD04-13G or TD04-15G for installation, it`s a good choice, I think.

I have a Uniq+ piggyback chip to adjust fuel and boost so its not a problem and I have a 5th fuel injector to put in extra fuel, I will just get a bigger 5th injector if needed, this will be done on a dyno.

I have the TD04HL-15G how does it differ from the TD04H-15G?

Most guys here say the 13G will be a good upgrade.

13G will be a little, would take at once 15G I has put such, a good choice and as capacity 200hp is provided

Hi guys,

I want to spec a Garrett GT25 or GT28 for the car but not sure what A/R I should go for? Help please?

GT25R

.64 or .48 A/R?

or

GT28R
http://www.atpturbo.com/mm5/merchant.mvc?Screen=PROD&Store_Code=tp&Product_Code=GRT-TBO-002&Category_Code=GRT
.64 or .48 A/R?

It`s better check whole maps of compressor wheels than to compare AR only. Turbine side either 25 & 28 absolutely same, but compressor wheels are different. 28R will provide more boost for sure, but for 1300cc I`d better prefer GT25R. But if you are planning to change pistons, connecting rods etc. then to shift the red line up to 8000, in this case - 28R will be ok.
You could check map and compare pressure ratio, it`s self explanatory.

Waiting for new 1/4 miles results

ok cool thanks! I think GT25R with T25 inlet flange will do the trick! I am also looking at the TD04L-14T, want to compare the prices first and make my decision from there.
