ok, as you can see in my sig, im getting lotsa fuel!! im tryin to decide what to go with and i have a 6speed so i have a little more play and less driveability issues than an auto i know.
I have my smarty(SW4) stacked with my quadrace(on 130hp) maybe pushing 450hp(?) but not dynoed yet(with quad alone i did 403hp/711TQ) and get plenty of fuel especially when i tried SW9 alone! I know ill be able to spool a 64 easily and maybe a SPS66? Im tryin to decide on b/w the SPS66 and A5K in relation so driveability. I drive a bunch and alot is highway...........tow once or twice a year(maybe) and do the drags on the weekend...well whenever i see someone to race highway or stoplight.......I want stay away from buying a turbo every year and be able to put some miles on it since i do a good 30K/year. So the question is which is best in regards to driveability, durability, and good spoolup with room to spare as my mods increase?
thanx

Iwould think the sp66 would be a better choice due to th efact you have a wastegate that you can set if drive pressure gets to high.

 

I wish I had a 6-speed for my Aurora 5K it would be a dream then.. If you don't tow then go big!!! 5K. M

I have had a 62 (B104) and a 66 type turbo. The 62 had a slightly deformed compressor wheel after a short period of time (like 3 or 4 months) and the 66 turbo had a thrust bearing failure in 6 months.

My Aurora 5000 is still going strong after almost 2 years of sledpulling and daily driving.
The Aurora takes a couple more hundred rpm's to light up compared to a sps66 but you also get benefits of lower egt's at WOT, and more hp etc.
ATS also provides a 3 year/150k mile warranty with the Aurora 5000. I think it covers everything but a broken shaft (from abuse).

In the end you have to make the choice for yourself.

PS the A5K is pleasure to drive on the open road/highway.

 

Lets say i buy a used one.....does the warranty still apply?

 

I dont know either way.
