Someone told me they will be good for around 500 rwhp at 1.2 bar.
I think I'll get them as a start and then later exchange for some newer turbos if I feel the need for that.
They look like this:

I can get two for $400
Ok, and if they are not ball bearing?
Someone offered me a set of Garrett TB2531 turbos. They are journal bearing turbos. The 2.3L Saab 9000 used one of these to get to 200 hp.
I don't know much about them but I can get two for next to nothing.
The A/R on the exhaust housing says 0,49...
I already have the HKS cast iron twin turbo T25 manifold. So no need to go OBX. Btw those OBX are not ball bearing turbos as far as I can see.
I found a set of GT2860R turbo's on ebay. I'm going to place a modest bid on those ans see if I'm lucky. That setup should be good for 600 hp...
I have a few experienced friends that will take care of the fabrication. I also have a few pictures of the same setup on an other 7m engine so it might not be that big a problem.
But I'm reconsidering everything at the moment. I see someone is selling one of Ron Ramirez's exhaust...
ATTENTION !!!
These sidemarkers will NOT fit in the front fender without modification
One of my friends just bought them and it seems they are just the rear marker ones found on ebay. It's a huge scam.
Buy the ones Richard makes.
ok. If the twins are not going to be significantly worse than a single setup I'll go for the twins just for bling of it.
So I'll se if I can find a set of gt2554's
Ok. I will take this into consideration.
How about the power delivery curve? Will there be any difference between twins and a single? Assuming both setups have been properly sized?
I know that running the turbos in parallel will cut the displacement in half. I assumed that there would still be a (slight) advantage using two smaller turbos instead of one big turbo.
On the other hand the manifold might also play into the equation. My HKS twin turbo manifold is rather old...
So it'll be something like these: http://cgi.ebay.com/ebaymotors/Garrett-GT2554-GT2554-Turbo-Turbocharger-64-A-R-T25_W0QQcmdZViewItemQQ_trksidZp1638Q2em118Q2el1247QQcategoryZ33730QQihZ013QQitemZ230272338053QQrdZ1QQsspagenameZWD1V
It says good for 170-270 hp.
As a rule of thumb, can you...
I'm going to twin turbo my 7MGTE.
And before you say it's not worth it, I say it is.
End of discussion.
I've got a HKS twin turbo T25 manifold here.
So I'll be looking for a set of T25/T28 turbos.
My power goals are somewhat modest. Around 450 rwhp. I'd rather have less lag and...
Great car. Congratulations !!
Did it come with TEMS or did you add it? It looks to me that you have both TEMS and seat heaters. One of them must have been added later on.
If you added TEMS, was it a big task?
I'd like to this myth verified or rejected.
If someone with logging capabilities got hold of a JDM ecu it would be possible to see how the two ECUs handle the timing.
As I stated before the older pre 89 supras in europe (at least according to my information) have the same ECU regardless...
They say that the lights will fit. It's a simple bolt in solution.
Anyway, the european supras didn't come with the rear markers. So no point in marketing those here.
