Thanks man! Should have this running this weekend. Just finished modifications to my upper and lower radiator hose. New silicone coupler coming in tomorrow should finish that off. Just need to complete the radiator support, and hook up my new gauge senders. Pretty good feeling.

OK. Got my new coupler today and finished a few items up. Started to put it together to see if everything will work. So far it looks good. Probably take it all apart and paint it up.

Thanks! Turbo should support at least 1000 at the wheels. I haven't seen any guys running this turbo on lsx applications. It's too bad cause it's an awesome turbo but it's more expensive than the usual setup used here. There is some info from supra forums on turbo dyno data. The engine is a forged 383 with worked 241 heads.

Yeah, the physical size of the turbo, at least from the pictures, looks small and compact. Where did you get it from if you dont mind me asking? How much? If you would rather not comment on the second question i understand.

It's a Bullseye S374 with the billet batmowheel compressor wheel, new race cover and an upgraded 87mm turbine with Bullseye's vbanded inlet stainless 1.3 a/r housing. Purchase price was just under $2900. Hopefully when I really start making some power people will take notice and understand that you don't need a 80mm turbo to put down big power. It's all about having a hotside that lets the engine breath, and a compressor that produces the air/power you are looking for... Not having some corked down turbo that unleashes hundreds of horsepower with a turbine hosing up size. Compare the compressor and turbine size to others on the market and you will see the difference. My setup is making 700 ftlbs at the tires at 3500 on 9 pounds. I love this thing and i'm so happy I spent the money and a turbo that made sense.
The reason the turbine looks compact is because of the Bullseye turbine housing. The T4 housing would probably be much larger. The compressor cover is huge though. 3" outlet ad 5.5" inlet

I liked the turbine housing material and size. It packaged real well with my setup. I know that the sizing of this turbo was spot on for my goals and engine size. I just really knew that this was the turbo for me! If you want send me a message and I can put you in contact with the guy for this purchase.

So I installed the largest griffin radiator I could possibly fit in the space provided by my frame rails, and noticed I had a warm running issue going down the road. My new 17" fan setup seems to work real nice with hi and low speeds. Right now in just 65 degree weather just the low speed is being used. I just want to post for people to know how important the air dam is. I have a 19" tall 1.5" dual pass, and its was still hovering around 200 driving down the interstate. I modified the factory air dam installed it last night, and went for a drive. Rock solid 190 degrees even at 35 mph on side roads.
