i've been searching for a turbo for a bit now and i understand a bit but not to the extent that i should which is starting to frustrate me
i have a 2.4 ld9
all im going for right now is roughly 260hp @ the wheels and i know the T3 Super 60 is always a great candidate for our motors as well but what trim/ar is gonna work for low lag and produce the #'s i want?
i dont care if doesnt hit full boost til roughly 3500rpm but would prefer full spool around 3000rpm
i apologise for having yet another post but i havent had any luck and this is my last result
thanks for your input and time
scot
The T3 super 60 will spool around 3k rpm or sooner. I purchased mine from down2turbo off of ebay it was the cheapest. I think you will be happy with it.
~Boost. Its what's for dinner!~
i got my turbo from www.ATPturbo.com and they are definatly good guys to deal with... the beat any price i could find as well not even 24hrs later after ordering it, it was sitting in my living room... thats fast delivery if you ask me... and that was from california to calgary... so it would be to the same for you scott...
here is one turbo which would probably put you into a good part on the turbo map... but if you even wanted to go to 300hp this would have to be changed but on the up side you would have quick spool up with this turbo....
T-Series T3 60 Trim
if you want somthing slightly bigger with maybe a bit more spool up time but has the flexability to go over 300hp if you ever decide to you could go with this one....
T-Series T3/T4E .58 45 trim
The First Twin Charged jbody
blue car (R.I.P) - 240whp @7psi..
silver car - 305whp 315lbs.tq @15psi (91 Octane) or 420whp & 425lbs.TQ @20psi (94 octane+Alcohol Injection)
All dynos run on a Mustang dyno
I'd suggest a t3/t4 but thats me...

any other insight out there?
Do you plan to run this on a completely stock motor?

Chris: this will be on the stock motor for the time being until i can get my other one built
Jared: is that 240hp supposedly at the motor or wheels and what psi is it efficient to and i would prefer it to be externally gated
for the sites that u all left, those r just for the turbo, did u all get kits or what, do u kno where i could find a kit for a turbo or would it be easier to order parts ceperatly...? i need help too i want to turbo my 98 cavy ASAP
I built my kit from scratch. There are a few companies on the .org but it's hard to tell you what your options are without telling us what engine you have. Also, why do you need to turbo your car "ASAP"??? Boost isn't something to rush into.

Also, I believe you're referring to
this thread (I made the maps, PJ elaborated
).

chris: for the true super 60 what is the trim and ar of it so i can go abouts looking,
and with the super 60 what will it be able to run psi wise before compressor surge cause im really wanting to hit that 260whp mark.
i will be running a HO manifold if that helps and i might try the secret cams and i already have my 62mm tb installed
i appreciate your help immensely
how bout this?

I'm not sure you're quite ready to be thinking about purchasing a turbo...a little more research into how and why they work would probably be a good idea.

'super 60' is the trim. It's related to the inducer / exducer ratio of the impeller wheel. Since a 'super 60' turbo is judged by the wheel only, you can get it with whatever a/r you want...both compressor and turbine housings. For your app, I would suggest a .60a/r compressor, and a .63a/r exhaust. Some people get the smaller housings (.42/.48) to reduce spool time, but it will limit your power and top end. Mike K put 400+whp down with the .63 turbine housing, so there will be no need to upgrade that later. Also, my stock lil LN2 spooled 9psi almost instantly with a .63a/r/.60 60-trim, so lag will definitely not be a problem.
Still, as you can see in the thread I linked, I would recommend .63 T3/ 50trim T04E for your motor. This won't be much a hindrance right now (as far as spool time), and will let you run 400+whp later if you want.
You mentioned compressor surge as being related to max psi...not really a link there. You deal with compressor surge when you try to run a lot of boost from a big turbo on a small engine at lower rpm (or when you have a faulty BOV). Your "max psi" as you say will be determined by the rest of your system. The more you compress the air, the hotter it will become. With a better cooling system (big FMIC, alky/water inj), you can safely run more boost. You will also want to retard your timing when running with hotter air to help deter detonation. The biggest factor in how much boost and how much power will be your tuning, don't cheap out there, and don't rely on band-aids.

The turbo you listed is a 60 trim, very close to a super 60 (chances are that you'd never notice the difference). If you're planning on building your engine later, why get a little turbo that you'd have to replace? GO 50 TRIM
