Spangers Posted March 28, 2007 Share Posted March 28, 2007 Hey guys Since I got my car a couple of years ago I have always wondered why I didnt get any boost while reving the car at idle. I originally thought this is normal due to the larger Garret TD-04 on my RB20 but I was never sure. Anyways to put it simply, if I rev my car at idle (after being warmed up) the AVCR will never show positive boost (you can hear the turbo isnt spooling no BoV etc). I am running a Garret TD-04 with GTR frontmount, APexi Bov connected to a wastegate and screamer pipe. Is this normal? I can provide more details, pictures, video etc if any1 needs more info.

paulr33 Posted March 28, 2007 Share Posted March 28, 2007 engine load makes exhaust gas exhaust gas drives the exhaust wheel the exhaust wheel drives the compressor wheel the compressor wheel drives boost pressure as there is no engine load the exhaust wheel doesnt spin fast enough which in turn doesnt drive the compressor fast enough which in turn makes little or no positive manifold pressure Link to comment https://www.sau.com.au/forums/topic/162250-no-boost-when-stationary-problem/#findComment-3013510 Share on other sites More sharing options...
R31Nismoid Posted March 28, 2007 Share Posted March 28, 2007 I originally thought this is normal due to the larger Garret TD-04 on my RB20 but I was never sure. Garrett never made TD-0X So its probably a Trust/greddy turbo you have on your car Link to comment https://www.sau.com.au/forums/topic/162250-no-boost-when-stationary-problem/#findComment-3013707 Share on other sites More sharing options...
silman Posted March 28, 2007 Share Posted March 28, 2007 The mitsubishi eclipse turbo - 1995-1999 came out from factory with a T25G that utilises a mitsubishi turbine housing. A TD04.

R31Nismoid Posted March 28, 2007 Share Posted March 28, 2007 Ye, but the rear housing for the Mitsu's is not the same as what the skyline is going to use. If someone has put a Mitsu turbo onto an RB... what a bloody headache that would have been. Check the rear housing dude if you can.

silman Posted March 28, 2007 Share Posted March 28, 2007 (edited) I need a pic of the other side. That looks like a T04E .5AR compressor housing to me. Seems to have a 2.5" inlet. That's the exact same compressor cover i had on my "50 trim" T3/T4 on my previous 4G63T Eclipse motor. In the DSM side of things in the states in around 2003-2004 the big thing was to match T04E Compressor covers with TD05H turbine housings. You may have that type of turbo installed. Can you clarify "When I bought the car it said it was a TD-04" (what is "IT") is that a sale description?, or is that what you see on the turbine housing?

R31Nismoid Posted March 28, 2007 Share Posted March 28, 2007 Ok, so garrett saying they didnt make a TD04 was slightly incorrect. My apologies. They made a few insignifgant models. I know the whole TD0X range is common, but look who its made by, and look @ the rear housing. Its not the mitsu rear housing is it? No. Link to comment https://www.sau.com.au/forums/topic/162250-no-boost-when-stationary-problem/#findComment-3014087 Share on other sites More sharing options...

You were right nismod, garrett didn't make any TD turbos, They made garrett turbos with oddball housings to suit mitsu flanges. The TD description cannot be applied to a garrett turbo as it describes a mitsu turbo http://www.atpturbo.com/Merchant2/merchant...tegory_Code=BCS hmmmmmm.......this looks like your turbo silman and the product description says t28. I also know that the comp wheel on your turbo is definately old 25 styles and looks very similar to the plain bearing sr turbos of the 90's. What?, TD05H-20G AND TD06-20G made by mitsubishi with garrett style exhaust housings? That must make them mitsu manufactured garretts!

Spangers Posted March 28, 2007 Author Share Posted March 28, 2007 Its hard for me to take a shot of the rear because the turbo is heat shielded but this is what I got; Link to comment https://www.sau.com.au/forums/topic/162250-no-boost-when-stationary-problem/#findComment-3014430 Share on other sites More sharing options...

Before you make more of an ass of yourself I suggest you go to www.dsmtalk.com and use the search button to look at what turbo came stock on the mitsubishi eclipse second generation - from 1995-1999. Perhaps you would most likely recognise this shape of car as the green eclipse from the fast and the furious, except the car in that movie was a non turbo 420a 2.4 non turbo fwd. The turbo i pictured is a TD04/T25G that was made by Garrett and assembled at Illinois on the 4G63T engines that were made in japan before being shipped to the usa to be assembled in the cars. they were all left hand drive vehicles. some made there way back to Japan, others made it to europe and even Taiwan. When turbo naming conventions are discussed the turbine side is always the denominator - eg T3/T4 or TD05H-20G. There is no difference here - TD04/T25G. Where did i say that the TD05 AND TD06 was manufactured by mitsubishi with a garrett style housing? This was a turbo most notceably made by forced performance to cater for the aftermarket scene before they all decided to concentrate on going completely Garrett. If you actually read what I typed it said that the Garrett COMPRESSOR HOUSINGS were mated to the mitsubishi TURBINE HOUSINGS. IE on the 1st generation eclipse from 1989- 1994 the TD05-14B was modified to fit the garret cold side compressor wheel and compressor cover.

silman Posted March 28, 2007 Share Posted March 28, 2007 Can you confirm the dump pipe diamater size? looks like it is internaly gated and has just an oil line. Is there a water line?

BHDave Posted March 28, 2007 Share Posted March 28, 2007 Thats real nice, we're already reverting to name calling You said What?, TD05H-20G AND TD06-20G turbo's are very common on Skylines. I said What?, TD05H-20G AND TD06-20G made by mitsubishi with garrett style exhaust housings? That must make them mitsu manufactured garretts! How was your comment relevant? Other than to point out that mitsubishi do manufacture T3 flanged turbos in the same way that garrett manufacture oddballs, yet we dont call a t3 flanged TD05 a GT2871 and we dont call a TD06 a GT30. That was my point. So i will say it again, just so that i can make a bigger ass of myself as you put it. I'll even put it in capitals. GARRETT DO NOT MAKE TD04'S. MITSUBISHI MAKE TD04'S The turbo pictured is a T25 with oddball housings (and core for that matter).
