Sure you guys get a lot of questions about this, and i know its a big turbo, but i got a deal on it so i bought it with the rest of the kit.

The setup

B18B block
GSR pistons
GSR Crank
GSR Rods

B18C1 Head
ITR cams
GSR valves
GSR Springs

The Turbo Setup:

AFI Ramhorn Manifold
Turbonetics 60-1 Turbo .82 AR exhaust housing
4 bolt 3 inch Full race Downpipe
1000cc injectors (overkill, i know, ill grow into them)
Tial 44mm WG
Tial 50mm BOV
Big *** FMIC

My exhaust, i believe, is only 2 1/4, so another quick question is should i run open DP because of how restrictive it will be, or simply not install the kit until i can afford a 3 inch? is open DP way too loud?

This will be my first boosted setup, and as you can see the LS/v is essentially a GSR, bone stock, fresh rebuild. My question is, is this turbo too big for a stock block GSR? (or ls/v, whichever) I plan on going to around 300whp for now, and from what i hear the 60-1 will do that on 7 or 8 PSI. I know I wouldnt hit full boost until 4600 or higher, and thats where my question originates, will this be too big of a turbo for me to enjoy my first boosted setup? Will the turbo lag eat at me? Im just wondering if i should throw this 60-1 up on the marketplace for trade for a smaller turbo.

I do plan for higher goals in the future, I have a friend with a built/sleeved GSR bottom end hes willing to sell when i have the money, but that wouldnt be for at least 6-8 months.

So should i just tough it out with a big turbo until then, or will I enjoy this size turbo seeing as its my first boosted setup, and just grow into the kit that i have?

Edit: Also i might add the car is a DD.

 

you will be fine.

 

How much effect does the larger .82 exhaust housing have? Does this just make for topend power less torque?

 

No, should be damn perfect. How exciting.

 

thanks. im pretty stoked to be boosted for my first time. Anyone got any answers on the running open DP or just run it through the small 2 1/4 exhaust? If i replaced the exhaust with 3 inch after having it tuned on 2 1/4 would it cause any issues without a retune?

 

Yes it will throw the tune off alittle

I ran my turbo open downpipe but I didn't want any restrictions as I street race

 

I think its waayy to big.. im sure the late spool doesnt help.. but its your ride , do what you want.
I would use a .50 or .57 trim myself to keep in the efficiency range.

 

says the guy who apparently knows absolutely nothing...



OP: That turbo is far too large for your stock block setup and goals. You could make the same power with a smaller turbo and actually enjoy having a powerband. Making 300whp on an LS/V isn't difficult...a 50 trim will easily do it and will spool a solid 1500 rpm faster than that 60-1. A "normal" 60-1 in a .63ar is too large...your .82ar is FAR too large. Couple that with a tiny exhaust and you get full boost at 5000+rpm. Do yourself a favor and buy either a T3/T04e 50 trim .63ar OR a straight T3 Super 60. Either one of those turbos will make 300whp on your stock block on pump gas AND be fun to drive. Trust me

 

I have to agree...

 

my turbo is a little smaller than the 60-1. Im running a garrett 57 trim with .48ex. I was in the same boat as u cause i have 2 1/4 pining, but worst my muffler is a stock civic dx muffler, so u know how small it is. My downpipe from the turbo is 3inch and I tuned it open down pipe and it runs absolutely good with the 2 1/4 and stock muffler bolted up to the 3 inch. yea i probably make less hp by restricting the 3inch with the 2 1/4 and stock muffler, buts it's absolutely fine for daily driven up to a point i believe, im making 300whp on a lsv. good luck!

 

I had one on my lsvtec with a topmount and it would make 6psi by 4800 then vtec hit went straight to 16psi. Made 389hp on a rich tune.

 

Like schister said, you will only start gettin boost at around 5000+ rpm and if not more. I can vouch for this cos I just installed a Garrett T4 with a .81 ar hot side and even on a built H22, it only STARTS to build boost at around 5000 rpm...

Maybe you should try it and see how you like the "feel" of it...

 

You'll be fine. I had the garrett version on my lsvtec with 9-1 compression. Let me see if i can fine my dyno sheet. Not sure if there that much difference between the 60 trim vs the 60-1 but on my stock head Ls and the 60trim with the 82ar it full spooled 23psi at 5500rpms

 

Hey 550, not tryin to threadjack but if you ran that big turbo at low psi (about 7) would the bov be very quiet? This is the only issue I am havin now while I am waiting to get tuned for high psi next week... what confuses me though is that my old tune on a small 50 trim with 8 psi was super loud with the same bov...

 

I was running a very similar turbo with the same goal of 300ish hp. I had a .82 gt35 and I loved it on the street. It was just lazy enough to get you rolling and then power came on for top end. It was full boost of 9psi at 4500 in 2nd gear. My car ran a 11.89 @ 116 on shitty BFG radials with that setup. Oh and it did make 309hp tuned by Matt Shue.

That turbo seemed nice for traction on the street and track but I do wish I had kept it. I found a good deal on a t3t67 and man is that thing LAZY for some reason. I will be buying a STC reaper from Shodan soon and if you are in the market for a NICE turbo that is capable higher hp and still be streetable for driving around I would look into it.

 

It depends...

Its all about the air volume and how big/small your bov valve is. Moving a large volume of air through a small opening makes the air move quickly, ergo louder. Honestly, there is no point to run a 60-1 at 7psi when you could get a smaller turbo, run more boost and make the same power with a better powerband.

I dont see why everyone wants to run such grossly oversized turbos. On my STi, i'm running an HTA 68 and should make ~340awhp/~380wtq @ 20ish psi (still running low boost on an AP tune). That turbo is a TD04 (sub-T3) and significantly smaller than the 60-1....for the same power

 

I agree with what some others have said, that exhaust housing is too large for that setup. Something smaller would be ideal for your stockish build.

I have a 60-1 with the standard .63 exhaust housing on my built ls/vtec with 10:1 cmp and Pro 1s and it spools up almost too quickly.


Like Schister66 said, everyone just picks the biggest number turbo and assumes it will work best.......... Do some research and choose one for your setup and goals.

 

Learn to read a compressor map and find the efficiency range for your goals.

thats how you pick a turbo, not cuz some dood down the street uses XX brand or XX size

 

Sorry for the misunderstanding guys, the only reason I am on 7 PSI is cos I am waiting for it to get fully tuned for high boost. However, I do believe that it is still too big but then I can't really tell now if I will like it AFTER the high psi tune... so confusing! I guess I might take it to my tuner and see how it "Feels" after the tune...

The 7 psi tune thats on there now is when I had my 50 trim .63ar T3.

 

I think you're putting a little too much emphasis on the boost level...that isn't really the concern here. If you do decide to run the 60-1, you're not limited to a fixed "7psi" limit...you can run whatever boost you want in order to make ~300-350whp on pump and more if you have access to E85 or race gas. Planning for the future is great but for your current setup, this is a less-than-ideal turbo. As long as you know that going into it, you won't be disappointed.

 

i dont know about the turbonetics 60-1 turbo but my godspeed turbo which is more like a smaller custom 60-1 turbo by just 1mm on both inducers and both exducers. with my 1.8 liter b18b with 9.1 compression i get full boost of 20 psi at 5500 rpm and it is definatly better than any t3 t4 turbo. sure there is a tiny ammount of lag but like someone said here earlier, its literally just enough to get your car going without losing traction for the street. and boosting a larger turbo also leads to less detonation and cooler efficient air.and it also makes the bov alot more quiet when ur cruisin around. i hate crusin in boost all the time like neons and subarus. its a burn for police and isnt neccesary. just go with the 60-1 turbo and u wont have to buy another turbo down the line. i also got a gsr tranny so that might have something to do with it

 

you seriously just bumped a year old thread for nothing but useless info?
