which turbo SPS66 or A5K?

[drasko]

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

You won't have ANY trouble spooling a 66 class turbo, the a5k I don't know. I think and I repeat think the A5K will spool a little slower. I too run about 30k mi per year and I have about 55k mi on my sps66 without any troubles and it has barked many times. I never tow any more than 3k lb, so I wont speak to towing manners. Not much help, I know, but it's all I got!

I just towed 10k with my SP66 and a manual trans - no problem at all. You just have to run the gears all the way out when up a hill... .

Send a PM to Joe Donnelly. IIRC, he has run both the A5k and 66. As I recalls, he likes the 66 better. Might have been in the latest TDR mag, too. Can't remember... ... ...

two very different turbos... go for the in-between... a silver bullet

I agree 110%... The AK5000 is good turbo for a compound system or with someone with even more fueling mods than what you have like Mach 6 injectors or something, but with what you've got the AK5000 would be a dog... Silver 66 would be the best bet.

Dont be a chicken like the rest go for the Aurora. I have had both... they are worlds apart.

I know it sound like a COMPLETE LIE... but after this turbo install and the associated parts like studs... . i will be calling it DONE on this truck and gettin a 12v for the FUN stuff..... so again SPS66 or A5K with no injectors but maybe the FCA Relentless diesel mod on the CP3

 

[Forrest Nearing]

well, if you're ONLY picking between those two (why limit yourself to just an sps66?) they're so different

Trust me, you'll never be "done". . haha. . It's a sickness that most of us share here on the forums. You are now headed for a life of a smaller bank account, more woman problems, and the feeling of only being satisfied for short periods of time. . If you really don't plan on going with more fuel in the future (dual pumps, large injectors, etc), and the fact that you have a manual trans, I'd go with the SB.

You might want to check out HTT. I just installed the new HTT Stainless steel 71 series 66/16. I'm making about 560 hp and 1060 tq with room to grow. I was running a HTB2 64/12 and I really don't see much of spool up difference. The 66 spools at about 1800rpm and pulls hard all the way up to 3500rpm making 55 pounds of boost.

The turbo of choice would be a Silver Bullet! I feel curtain that your truly will test this one to the edge this year.
