Right now I am working on my second turbo build. As of right now I am on a Greddy turbo kit with supporting mods. My end goal for the car is 400whp. I have been going back and forth between 3 turbos. 1. Garret t3/t4 60 trim .63 a/r, 2. Garret 60-1, and now 3. Precision SC61. What would be your choices for my goal. This is a 2.2 H22 for those who dont know. My main concern it spool up time. This is a daily driver so it needs to be around the 4k-5k latest. Thx

 

I would have you look at the STC Silver Surfer. It will make 400whp and spool around 4000rpms if not before.

More info here

 

on a big h22 at least the 60-1 if you have a few $ more sc61 is a good choice but you will be very happy with 60-1 your spool time will be just fine and if you go any smaller you will kick yourself

 

i run a precision sc61 bb. it runs beautiful, and will go over 500hp if you need it. im full boost well before vtec.

 

thx guys... I think im going to go with the 60-1

 

ever thought about a gt3076r? if spool time is your main concern this is the turbo for you.

What is a ball park price on those??

That is a great match to your setup. Now you need to look at the turbine side. I am not a fan of the Stage 3 turbine wheels and you having 2.2L it would really benifit you to get a bigger turbine wheel. Like a stage 5 or "P" trim.

1150 shipped.

 

If I am going to pay over a $1000 for a turbo I will be going with a GT35R.

Whats wrong with the stage 3 turbine wheels? I read up on people using different wheels but didnt really think it was necessary to change it. Thank you for the info

 

The 60-1 should work pretty well on your setup, but the Silver Surfer that was mentioned earlier is basically a modified 60-1. The design of the 60-1 is fairly old and the Silver Surfer addresses that. If you're not really concerned with max efficiency, then a $500 60-1 should more than do the trick for you

 

go with Garrett T3/60-1... 82ar housing w/ stage 3 wheel. that will be the best set up for h22.

 

Was thinking about the .63 a/r... a bit faster spool. Do you think it would kill the top end?

Plan to buy from rogueusa...pretty good prices http://www.rogueusa.com/Garret...1.htm

 

i've run several turbos on my gsr, and nothing comes close to my gt3076r .. i got it from evans, vband, polished housing for about 1300$ compared to a same size non BB , it's night and day. boost starts coming on under 3k. and it makes about 410whp at 14psi.

 

Well a turbo that spools to quick, imo, isnt all that good for a daily driver or street setup. If it spools under 3000 in the gsr it prob will spool closer to the 2500rpm mark with the h22. I would like to be fully spooled around 4000-4500rpms. A bit more economic too

I have been sitting in front of the computer now trying to write an expalnation and I couldn't get it to make sense so I will give a REALLY Short version.

When the compressor wheel and the turbine wheels diameters are SO different they want to run as different speeds. The compressor wheel dictates the shaft speed and bigger compressor wheels run at lower speed to make XX amount of boost what happens to the turbine wheel is that is gets UNDERDriven when that happens the work that it does (turn the shaft) is done very inefficently (it can easily drop anywhere from 2-15%) which just contributes to lag.

I have never been able to do any back to back testing, but I have done setups with the different turbine wheels on different cars and the general consensus is that going with a larger turbine wheel it usually spools about the same as the Stage 3. The back pressure is lower with the larger turbine wheel (which everyone now will make more power).

I have to head out I will talk about this more later.

your main concern seems to be that it spools as slow as possible lol. quick spooling turbos are the best for street cars. a gt35r is overkill for 400whp.

you will see full boost(around 14-15psi for 400whp) around 3900-4k with the gt3076r.

I have to agree with that....idk why you'd want a shitty powerband on the street. I'd much rather have a fast spooling setup like i have right now

 

I cant afford to spend $1000+ on a turbo when I am trying to get my second setup done before next year. I just got done with this one... I have been boosted for about a month lol. I still have to build my block, buy a wastegate, turbo, and pay for tunning. I already bought a revhard manifold and a stage 5 competition clutch kit. mike@synapse motorsport do you carry 60-1's also? Maybe I should put the extra money towards the turbo tho. It is Journal vs Ball bearing. Mike what is your honest opinion? spool up characteristics between the 30r and the 60-1 should be about the same correct?

 

the spool between the GT3076 and the 60-1 are hardly comparible....the GT30r is going to spool noticeably faster than the 60-1. There are other options than the 60-1 if you cant afford/justify spending $1300 on a turbo. It isn't like you have only 2 options.

IMO investigate your options more before deciding...you dont have to get a ballbearing turbo to make 400whp...as much fun as some of them may be

 

Basically those are my options lol. Daily driver requires pump gas. I dont want to be pushing anything past 20psi really for my setup. I would love to get my goal at 1 bar.

 

both make similar power per lb of boost and both have similar peak power potential but the gt3076r will spool much faster.. for your setup you will probly hit full boost about 400-500rpms sooner with the gt3076r.

the gt3076r is the obvious better turbo, but its a cost analasys. is it worth the upgrade for you.

we carry both turbos. the 60-1 is 650 shipped, and for only pennies more you can have a gt3076r. 50,000 pennies more.

edit: when i get to the shop tomorrow ill show you what a gt3076 spools like on a h22. we just built and tuned one last week. maybe i can dig up an h22 60-1 graph too.

yep waitin on the graphs

 

not to thread jack but can you guys help me pick my turbo. im looking for 600whp on 110 octane.

i was thinking 60-1 but i dont know if that can get me there. i got around $600 to spend. maybe a used sc63?

btw its a track only car.

 

i have a brand new sc34 turbo i'll let go for $600 shipped 0 miles
