I dont personaly care for ATS, so that alone would be enough for me to cancle the oreder. The 5000, if I remember right is the same as k31 which is smaller than a s400/b2. I'd personaly go with a s400/b2 set up. Probably cost you less to boot.

 

The K31 and S400 are apples to oranges. Both are very large and very close in size. I asked a Borg Warner employee what the differences were and he basically said the same thing. He said the S400 series was an american design he favored. He also said the K31 was from a German design and series.

An OEM performance borg warner K31 wastegated with large turbine housing and billet wheel that would be suitable for twins can be had brand new for $924.
The stock S400 can be had for around $650.

www.citydiesel.net has them...

 

I thought this to so i asked him if he meant the super phat shaft or the silver bullet and he said the silver bullet.

 

I went with a SPS62 (currently still sitting on the floor) for what is an estimate 500-550RWHP I'll have. I did a lot of pokeing around and I think that was the right choice for me since its a daily driver in all kinds of driving conditions. Also its not so big I can still use it as a small turbo in twins if I want to upgrade without throwing out a turbo. If you do go with an SPS62 and may want twins later when you order it ask them to make the wastegate bigger so it can dump more if you do put twins on it.

Cant you pair a silver bullet with a sps62 for twins?

 

There is a new Silver Bullet 62 which has different exhaust housing "work" and some special stuff done to the wheel...supposed to flow better for higher power!!

Do you know the differances between it and the sps62?

 

different (larger) turbine wheel

 

is that going to be laggy?

 

The guy that i talked to said it would be better for towing

 

Why doesnt he mean a silver 62? Ok by the time I read all the posts and made mine, someone already asked and clarified.

 

im running a super 62/14 with an edge comp 150 sticks and an auto. spools a tad slower than stock but when it lights hold on. its great.

 

,....... um cuz I had never heard of a silver 62 and have yet to hear any feedback about it

Here is a silver 62 thread for ya

 

II and HTT need to get on the ball with a marketing campain cuz these variants are really going to confuse folks.

So now we've got the s300's with the 58 compressor and 62, then 64 and 66 with a slightly larger turbine, then the sps/ ht series with the 71 turbine and now the silver bullet series with a 74 turbine. No wonder there are so many which turbo threads =\

Then back to the original poster's question, the a5k is a 71 compressor and 76 turbine,..... yeah I did a search
