My new t72 vs oem s4 turbo. picture doesn't do it justice. the s4 turbo is tiny. even for twins.

s4 hotside is tiny too. the arrow points to the actual snail volume area, the rest of the turbine is big due to internal gate

battle of the tiny turbos. left side is 13b from an auto 1g eclipse. right side is the audi s4. 13b is larger

hahaha! I saw one in Blittles shop and i thought my turbo was small..... the fact that a 13b is bigger is funny as hell!

S4 turbo looks like it would work good for a bike :)

people do use the s4 turbo's for bikes, more use the rs4 turbo though.... only slightly larger in comparison.... in fact the stock turbo off of an 89 mx-6 gt with the 2.2 SOHC turbo engine is larger than a ko3 (s4) turbo

I would imagine so, the s4 turbo is working with about 1.3liters or so, the 13g from auto dsm is 2.0l, then you have the 2.2 mx-6. We'll have to get in a stock wrx turbo and compare it to these 2 small turbos, the wrx's is around the same size.

I'll post up the bobcat skid loader turbo later.

there is a sale going on now for turbonetic's new billet 64mm wheel. probably flows more than their t66. interesting video here http://www.turboneticstv.com/featured_l ... reset=true (http://www.turboneticstv.com/featured_landing.php?reset=true)

good size for a supra or around 3.0 sized motor. would be really fast on a v8, the 5.7's sometimes run t66's but its smaller than the average camaro guy would run. maybe the 4.6 or 5.0 would be good if they want a fast spooling turbo. laggy on a 4 banger but not unheard of

Why do you have the k03 or 13b?

A pair of k03's was in the garbage at brian little's shop so Colton grabbed them. I'm not sure whats wrong with them if anything. i know one turbine to chra bolt is stripped out. the 13b is shot, came off of one of colton's parts cars.

I'll probably send the turbos through a parts washer and keep them in the office as a conversation piece. maybe drop them off at the powder coating guy next time i'm there.
