Are you sure that Minnam turbo kits use(d) the T3/T04B with their kits? I'm almost positive that it was/is in fact a T04E . T

My minnam turbo is a 'B'. The 'E' has a bigger compressor wheel iirc. FWIW when I had my turbo installed RalliSpec said they never had seen the same turbo twice in any of the minnam kits they'd installed.

The turbo, T04E, was delivered to the UPS center here at 5:00 this morning. It should arrive at my door this afternoon provided nobody had to sign for it. I will post pictures, as good as I can get, and a review as soon as I can.

I have a question. The turbo kit I just bought coes with T3/T4B. the turbine side is turbonetics T3 and compressor is supposely Garrett T4B. My question is, do I really have T4B? I just want to conform the type and find out the spec of it. The guy who sold me the kit tells me it's T4B but I can't really trust his words. The only info I have about the compressor is it has "Garrett" and "A/R .42" written on it. The compressor is slightly bigger than the turbine housing which is T3. Can anyone please tell me what compressor I have? The Garrett website doesn't tell me anything.

By the information given, there is no difference in the two turbocharges. T04e or b is referring to the compressor housing. Go get the box with all the specs and write us back with all those nifty turbo specs that don't seem to make any sense.

For all intent and purposes, the people who manufactured (who is it?) your kit will have the best information on this.

Garret, turbonetics, air research, they are all the same. If you would like more info on your turbo, you should really check out www.turboneticsinc.com

As for the A/R of .42, look at the compressor maps and it will let you know the A/R you want for the size of motor you have and how much power you want.

P.S. I barely understand the compressor maps, so good luck.

There is some good info here as well: http://www.turbofast.com.au/balstd.html

It looks like you can tell what you have by measuring the wheels. I don't see an a/r of .42 listed on the page though, but I don't know how complete the listing is. HTH

The problem is, there is no document abot the turbo's spec in the kit. The turbo itself was packaged in a plain box without anything. I could not find any compressor that has .42 A/R and that's why I was a little confused. I asked the person who made me this kit but he wouldn't tell me anything. I don't even know what type of compressor wheel I have. From the look of the trubo itself, it looks like it has been used before because there's little oil inside the oil feed/return holes and exhaust residue on the turbine wheel. I don't know if that's from testing the unit at the factory or if I got a used turbo but the fact that he doesn't tell me the spec of turbo bothers me a little.

Impboy, can you measure the wheels and see if that tells you anything? In a worst case scenario you can always send it out for a rebuild and then you'll really know what you have
