Nice build man. I'd like to get your opinions on each turbo setup you've had.

I'm thinking about the Gt3582r on an M52, but I'm curious on how you feel about the Gt30 compared to the Gt35.

Awesome build! Your videos caught my attention as I'm going to be boosting my 2.8 m52 also and already have a gt3071 but was thinking of the 3082 also. Also curious about your HG setup you mentioned you have steel plates? How much thicker is it over oem?

Saturday, racecar day. Few things changed:
- driveshaft bearing
- gearbox mounts
- steering pump

We also did wheels alignment. Rear changed from -3,5 degrees camber to -1,5. Fron camber set up to -2,2 degrees.
Wheather is bad, so didn't make any tests. Traction should be better though.

Yesterday video - my one and only pass this day.
I lost with BMW 135i (525hp/650nm), killed my driveshaft bearing and AFR sensor. Shit happens ;)

Overfenders installed.
Yesterday I met two police officers, who wanted to check my car. I wasn't speeding. I got a warning because of front wheels poke. So today quick action and here there are. They liked the car though

Another changes. Got my E30 M3 EVO wing installed once again. E30 with that wing is more stable at high speeds. Have to finally make it color match and it will stay there.




Today new springs arrived. Stiffer replacement for previous 140mm/10kg, currently 140mm/12kg (straight version). No comfort loss, rear of the car is not scrubbing the tires anymore. Also it's 8mm lower, as I took out one of the plates.

Haven't changed anything recently.. so I changed turbooo

I present you turbo nr 5. Nothing was wrong with the old one GT3082, my friend killed his turbo, so I sold him mine. And here it is, GTX3076 (ballbearing + cnc).

Quick thoughts:
- very very loud turbo, like old truck climbing the hill
- didn't change tuning, AFR went up - so more air in the intake
- quicker spool and throttle response
- 1.0b of boost is quicker, 300rpm quicker (more less 3200rpm now)

Some vid, first trip:

Search on ebay for BKC Motorsport.
Some asian company, don't remember which country :)

Wow, simply amazing. Who makes the intake manifold?

Last weekend video. Only 1.0b of boost, some boost leaks.



After that I ordered some stiffer springs for wastegate. Removed boost leaks and today made 1.35b of boost. It was fun, but my injectors DC is 87% (630cc) so I'm done. So went down with boost, about 1.2b. I bet some new, bigger ones will have to be ordered.

In the meantime, my friend sold me this "new" short block. M50B25 vanos. I have a plan to build fully forged 3.0 m50 during the season.
