Those of you running this super 75 turbo; it's a ridiculus oversized compressor for a 2.5L.
Just to put it in perspective: it's bigger than the turbo that Duke is using on his 16 valve high flowing engine which is presented on one of the threads here.
Laws of physics: the bigger the compressor the more exhaust pressure is needed to power the thing, given a certain size turbine wheel/ housing size combo.

As for the Lindsey #8 vs the "Porsche" #8; are you looking on the inside, where the cross-sectional area meets the turbine blades?
If it's a bolt-up turbo, wouldn't they both be kkk? It should be the same size. The original #8 had a 55mm wheel at the outlet. What size is yours?

 

The lindsey #8 is larger in every way possible, I had them both side by side and took pics. I believe they use a replica housing made by turbonetics, the turbine blade is bigger in diameter, and the inner tongue is wider. Just off the top of my head, I believe the turbine blade was 65-66mm, but im not too sure.

 

As a matter of fact, I found my old pic of three turbos on my tool box.
From left to right, the lindsey "8" hotside, the K26/8 hotside, and the k26/6 hotside.

 

Hey , that's a good pic
Looks like you have the 65mm p-trim wheel, so that's good.

 

I think exhausts that get larger in dia the further they get from the turbo are for making money rather than bhp.

 

The supporting mods are listed in the first post, many say the k27 is laggy but I find it barely lactose than the k26/8 I used to have a while back. Boost starts building around 3200 rpm in 2nd gear, which isn't too bad.

 

it doesnt rust!

 

and that's why i don't need to pony up the extra cash...I'm in TX! Many others could sure benefit from it, I think Lee is in Jersey.

 

does it rain in tx?

 

Yes, I am in Jersey... But I think the one factor everyone here is neglecting is the factory rust protection designed into the car. The chassis were dipped in galvanized zinc, but the rust protection didnt stop there! The 951 engine was designed to leak constantly, and the power steering system was also built in a similar manner. Once these car pass about 130k, and the galvanizing wears off, the cars automatically oil the bottom of the car and the exhaust system, ingeniously preventing rust

 

I've yet to see a rusted exhaust system in this area...I grew up in the midwest, believe me I know what they look like. A steel exhaust here will last a loooooong time.

They sure are purty though

 

bwahahahaha...

 

I live in the south and while the exhaust doesnt rust on the outside, they always rust from the inside out. I agree, get stainless. Aluminized steel is for cheapskates trying to save a buck, when it will cost them 3 in the future. Buy the right parts once, and they will last you forever.

 

Thanks lee101315 for the great turbo comparison photo...worth 1,000 words.

 

interesting point...so how long would you expect a steel exhaust to last in the south? Ten years plus+?

I do like saving a buck, my car is nice but not a showpiece and the chances of me owning and outlasting a steel exhaust is probably pretty low.

Don't get me wrong...if money was no issue I'd drop the cash on a stainless in a hurry. QUALITY for sure and gorgeous!
