someone wants to trade me this turbo for some sparco torino2 seats. What do you think. how much more money would i be looking to spend to finish the project (Mind you turbo already provided and this would be going in a 3l
 
now I don't know but something tells me by the name its way to small for a 3L ..... plus your looking at a few grand more then likely to make it all work. forget the deal as a 3L needs T3/4 turbo ...

you know the specs on that turbine? Is it one with a DSM flange or a t3 flange? a t3/t4 at 60 trim flows 53lbs per minute I think which is doable with an s200 turbo given the right compressor, but a t3/t4 is a little more efficient and is going to spool up faster. your costs will be lower if it has a t3 flange since the only aftermarket turbo kit for a contour uses a t3/t4 hybrid turbo. You could mix and match parts from the kit and some custom fabbed stuff. But unless you know a lot about turbos or have a lot of help from someone experienced, I wouldnt try a custom system. You will spend way more than you would just buying a nautilus kit.

really, if you want a turbo, just buy the nautilus kit. In the end your price would probably be the same just buying a kit from nautilus, their prices are REALLY good. I spent that much putting a turbo on my escort and I used several used parts off of a 323 gtr.

Plus anyone who works that hard at creating aftermarket parts for a platform like ours deserves your support. Most people would say to hell with a product that is going to sell as few units as a turbo kit for a contour.
 
Borgs are nice turbos, a s200 maybe good actually for a 3.0. I dont recall. s400's are big with the Mustang crowd, are good to around 800hp I think.....
 
I honestly think those S200's are capable of supporting a little north of 500. Only real drawback is a T3/T4 hybrid would probably spool up faster. I couldnt really say anything as to reliability, cause I honestly dont know. Besides, your seats are worth more than that turbo anyways, especially if that turbo is used.
 
thanks guys. i had no idea that this thread was still going unitl say umm 5:30 on a Sunday morning when i'm just getting from the clubs LOL

but surely nice to see that feedback isnt something one has to beg for around here.

and yeah my seats are surely worth more then $300 but just for your information the turbo was new.
 
lol i still have a bunch to learn about turbos because i dont know what a compressor map is. but i will research about it so i can help talk about the subject

Can you find a compressor map for this turbo? Is it new? It might be worth it.

I'm not saying it won't pump air at lower rpm but if you look at the pressure ratios on the left column you see that it doesn't go below 1.6 or so. Most likely the turbo would surge like crazy. The line on the left hand side of the map is the surge line.
That just means the designers wouldn't use this turbo on any applications below a pressure ratio of 1.6.
think of pressure ratio as a percentage above atmospheric. If you look at a pressure ratio of 1.5 you can think of the 1.0 as being equal to atmospheric, or essentially ZERO boost. The 0.5 is the amount of pressure above atmospheric, i.e. 14.7psi times 50%, or roughly 7.3 psi boost.


So a pressure ratio of 2.0 = 14.7psi boost.

The rings in the middle of the map called efficiency islands show the efficiency rating. Bigger = cooler air coming out of the turbo. This turbo is less efficient than the T3/4.
The s200 is most efficient running a pressure ratio of 2.4-3.0 (22-30psi boost) pushing 20-50lb/min of air. Perfect for a medium sized truck engine.

That T3/4 shows it's perfectly happy running a pressure ratio of 1.3-2.4 (5-20psi boost) pushing about 15-45lb/min of air, or ideal for a slightly smaller engine with a wider rpm range.
