Okay so im building an ls turbo, and ive heard from some knowledgable turbo guys in my area the super 60 with the .63 hot would be damn perfect for my build pretty much a stock ls with some minor upgrades for reliability under boosted conditions. now my question is im having a very hard time finding the exact super 60 that i want unless i just buy a god speed turbo and i dont know about putting an ebay turbo on my fresh engine..so anyways what are thoughts on optimal turbo size. Before i get any comments about reading the LST thread ive read most of the thread and what people are running, my goals arent near as high as most of the people running around in a ls turbo. around 200-250whp keep in mind this is a daily driven car and still will be so reliability is what i want along with very responsive spool time which i heard the super 60 is almost instant spool from what ive read and videos ive seen which i like but it doesnt have to be "instant". just looking for advice as far as turbo sizing for a close to damn near stock ls, with minor upgrades such as head porting, rod bolts, forged pistons and maybe forged rods. i like the idea of the super 60 but all i can find is ebay turbos for cheap. so any input on a similar sized turbo that would accomplish my goal i was looking into a t25-t28 but i read those are just damn small for the ls. so i think those are out of the question. thank you for the input.

you can get a garret 50 or 57 trim for that power level. you can boost tour stock motor , as long as this is your power goal. just make sure you have a good tuner

I don't know too much about turbos but are you suggesting a straight t3 assuming that because the super 60 is that. Power goal will be a Max of 250. Also considering bumping the compression just a bit. But not certain now. What about the a/rs? Sorry I don't know a ton just basic knowledge. Specs would be helpful. Thank you for the reply.

i think the 60 will have great response in the low to mid range, but it will run out of breath in the upper range. Id suggest a .50 trim. but if your only going for 250, then a 60 will work.

I just changed out my 60 off my b20 and it fell on its *** after 5500-6k. But with the low redline of the b20, it wasnt too bad.

What PSI were you pushing through it and what kind of power was it making?

man the torque is crazy. im not to savy on turbo specs to . but my old set up on my lst consisted of, ls block with cams, six puck clutch, and a cheap put together turbo kit. i made 231whp 191 wtq. i believe i would have been in the 12s on a quarter mile.

Undrboost

By 50 trim can you be more specific, those numbers are great for a b20 the torque is insane and that's not too bad for a b20 that's really all I'm looking for is about 250. But if the 60 won't be that good in the higher revs it may be worth looking at a larger sized turbo for head room and I can always limit the boost and have room for upgrades and turning the boost up. Can you clarify what you mean by 50 trim are you reffering to a t3/t4 50 trim. When it comes to numbers and turbos I have no idea..

The Super 60 would be a good turbo...if you want to go a little bigger, a T3/T04e 50trim would be a good step up. No matter which you pick, be sure to get a GM3bar map sensor so that you can get the use out of the turbo. Dont be worried by the boost pressure, but keep your power in the mid to low 300whp range and you'll be fine

Undrboost

Just any t3/t04 50 trim turbo and by 50 trim do you mean it saying like .50 a/r on the turbine side housing? What about the compressor side? What should I look for as far as the a/r? .48 .63? I just don't want to purchase something that expensive and not work how I intended too if you know what I mean. Thanks for the help!

i think you should do a bit more reading. it will benifit you alot.

Undrboost

ive been reading a lot lately on turbo stuff but i still dont understand some things mainly the sizing stuff, like i said in the OP thats why I'm here asking for help. maybe you know of a site that has the info on what it all means if so ill gladly read it and educate myself.

phaphon

have you read the faq's ?

Turbine Housing (Exhaust side)
As a rule of thumb, you don't want to run a .48ar turbine on a honda. Since honda engines like to live in the upper RPMs, the small housing tends to choke out. Similarly a .82ar is a bit too big for most uses and tends to be excessively laggy. You would opt for the "standard" .63ar turbine.

Compressor
There are compressor cover options too...you can get an E or a B cover on most standard T3/T04 turbochargers. There are other options, but lets not get ahead of ourselves. Anyway, the E cover is larger and will flow a higher volume at higher rpms. The B cover is smaller and provides more midrange airflow but with less top end flow. The combination you choose depends on your goals and needs for the car. For a fun, around-town DD, I would personally opt for a T3/T04B 50trim .63ar. If you have a little more money to spend, pm TheShodan and ask him about his GT32 line.

The best thing you can do for yourself is read. The FAQ at the top of the forum has tons of links to helpful articles and threads.

yup if i had a ls and wanted to make good powerband on stock longblock (IM/cast turbo manifold) i'd go with t3super60.

Undrboost

Thank you for the information this is what I was looking for I think I have began to understand a little more now. Ill continue reading up on turbos but this helps me out a lot on deciding.

I have ran a .48 ar on a t3t4E turbo and yes it ran out in upper rpm's past 7,900 rpm. but for a ls or non vtec they are a fun street turbo . I now have a 57trim compressor with a .63 ar turbine and it feels like a oem perfect match for stock B18C. you won't have any lag issues with either.

A T3 Super 60 is a good fit for your HP goal. The .48A/R will work just fine for what you are using it for. Good luck finding a Stage 1 .63 A/R turbine housing anyways. I am new to HT but have a lot of experience with turbos.

I ran a T3 Super 60 with a .48 A/R on my last turbo project. It spooled very quickly, but started becoming inefficient (ran out of breath) after about 6k. Sold the car to a friend who put a t3/t4 57 trim on it with a .63 A/R and it spooled a bit later, but made power all the way to redline.
