what are the advantages, and disadvantages of uprading a turbo from a E housing to a S housing on the compressor?
for example my turbo is at PTE for repairs, and I am thinking of getting it upgraded with the S housing, what horse power gain is possible on a sc6152e upgraded to a S

 

u wont see much of a gain from the cold side housing bigger. exhaust housing size is what gives you gains

 

but why do so many people are so crazy over doing it? it cost more fitment problems, than the e cover, and you have to custom order filters or make intakes, some people cant use a filter at all,
so to put one's self through that much trouble there has to be an advantage.

 

anyone?

 

For one it just makes your turbo appear to be alot bigger than what it really is. It looks better than the E housing...so I think its mostly cosmetics..other than that the only benefit I see is that since it tappers from the 4" inlet into the compressor inducer, it most likely increases the velocity of the air entering the inducer.

 

wouldn't it cause increases lag also?>

 

not really, the exhuast side is the key to boost lag

 

Bigger volume, more power. Bigger inlets, bigger outlets. Same theory as behind larger charge piping.

 

Depending on where your manifold sets the turbo the HKS filters fit perfect onto the S housings. Here is a pic of my setup below.

 

wow, be careful or do some research about that hks filter. ive heard people sucking the filter element straight out of the housing, straight into the compressor, and this was on an mr2 turbo, going through a MAF sensor. sorry to be off topic, just a warning.

anyways, i would especially like to see a dyno comparison between these two tubos, being that i am looking to tune my car this week on the sc6152e.

 

I am sticking with my hks filter, I see no way that the foam part get sucked in unless the user removed the webbing under the filter, or the filter was covered, or clogged with mud. I think its more sturdy than a k&n I see K&n sucked crushed on N/A cars all the time, so imagine on a turbo car after time. HKS FTW

actually hks suck compared to k&n there are many dyno graphs to prove this!!!

definately in flow comparison thats a given the k&n flows better, but the sucked in part was just user error in my opinion.

 

Yea the only possible way I see my filter getting sucked through the turbo is if someone modified the housing to remove the inner webbing. I love mine.

 

lol ok, it probably was user error, now back on topic! lol

sorry to OP.

anyone have any charts comparing the e and s housings on the same or similar seups?? in for more info/experience

Ok, stick to the topic please. Which housings?

 

I have the sc61 with the s housing. I remember when i was choosing a turbo there was a thread where someone was going to post a graph of but never did.I dont think you will find a side by side comparison.The gains you will get are going to be very minimal if you are trying to get alot more power you would be better off just getting another turbo?
