Garrett vs. Turbonetics

first off, id like to say i searched and found squat. anyways, im getting the sr20perf. starter kit with the Garrett t3/t04e (.82), but before committ i would just like to hear from you guys the diff. between the garrett and turbonetics t3/t04e (.82)? besides the stage 5 wheel, how much more boost/hp would i get from the turbonetics turbo?

which one would u guys go with?

There really wasn't much difference between them aside from a few more part numbers (I.E. Housings and wheels) being available from Garrett.

NOW with the Garrett GT series stuff, Turboheadaches only has the older Garrett Stuff.

If you are talking about the older non GT series stuff, it's pretty much all the same.

id say stay away from turbonetics. they used to be one of the leaders in high performance turbochargers but now it seems they only sell generic products. all the top guys there left and started innovative turbo. check them out as well as precision turbo. innovativeturbo.com, precisionturbo.com.

lots of turbo stuff for sale

- turbo
- manifold
- wastegate
- BOV
- JWT ECU
- injectors

if the wheel trims, housings, and a/r is the same, they are the same turbo. turbonetics balances their own. but really, not much difference. you want a nice gt37 with a t3 inlet?

If you are referring to the Ballistics stuff, the only same part is the center section. Housing are a different design. In order to run a Garrett turbo you have to flange it away from your F-Max style manifold and remove the oil separator piece of metal off the block. The external measurements on the Garrett housing are huge. It wasn’t fun switching over from the turbonectics. I think its only worth while to go Garrett ballistics if you are going to be running some sort of custom manifold or revhard, protech. If you are going to run an fmax manifold stay with the turbonetics turbo. Just my thoughts.

well, the turbonetics turbos use the older 5 bolt flange on the downpipe. these are a PITA to bolt on. If you get a protech manifold, you can order one that makes the ballistic series fit perfectly.

i would be wary of a journal bearing turbo though, mine died in 600 miles, totally dead. they arent very good at coping with thrust loads and there are others here who have had similiar problems.

I have an innovative turbo, it has carried me to a 12.6@117. I would have ran a faster mph, but the 100* weather and the massive misfire in 5th (20 psi and 20* timing tended to blow the stock ignition's spark right out, the car didnt even accelerate at all the last 300 ft). i expect 11s come this fall (damn weather will cool off by then, dammit)

a stg V wheel will be pretty lazy with a journal bearing though. i would get a stg III wheel unless you went with a BB center section. My stg V wheel spools quicker than my stg III journal bearing turbo did, same turbine housing.

I'm leary about the T3/T04E Ballistic turbos.. since you can only get 57 or 60 trim compressor wheels. Also, they don't have 360* thrust bearings. I have run several of these turbos on SR20's.. and the 60 trim flat out sucks. The 57 trim is decent.. but the 270* thrust bearing will fail at any decent boost levels.

i have talked to many people that know their stuff, that said the 60 trim is a waste. they all like the 57 trim better. i think it's surge line is further down then the 60 trim.

the guy that said he put on a garrett in place of a turbonetics....was the a/r the same? if the a/r is larger, the housing will be larger too.

OK guys the reason I brought back this old thread is that I have a Garrett turbo for sale and a prospective buyer said it wasnt as good as a Turbonetics. Its a .50 Compressor A/R with a 50 trim wheel, .63 Turbine with a Stage Three wheel (5 bolt pattern...Ballistic??). I know from searching thru these forums, and even grilling HotshtSR20 that these are the best specs for our cars (for moderate horsepowe/lag).
Now what I was curious about was, is it less effective than a similarly specs Turbonetics, because of thrust bearings or anything else?

PS - Also do the Turbonetics turbos from the FMAX kit come water cooled?

the difference between turbonetics and garrett is nil. there are only cosmetic differences. if they both have 360* thrust bearings (or 270*), both are (or arent) water cooled, etc, then it really comes down to 4 bolts or 5?

a stg III 0.63 A/R T3/T04E with a 50 trim compressor is a really nice turbo for our cars, and will happily shug away at 300-350 whp for a while. just dont run the boost too high too often.

What about a T3/T40E compared to the GT37 like the one jgy sells?? Is it best to stick with a T3/T40E? BTW, Hotsht, your innovaticve turbo, I assume, has a ball bearing center section? And is it water or oil cooled? Let me know. Thanks!!

Get a GT30.. or GT35... you won't be dissapointed. You can get them for 1300.00. Dual ballbearing, and very efficient compressor/turbine designs. You can run very high boost without having to worry about them failing.

Where could I find those?? Would these have the same bolt pattern/flange as the T3/T40E does?

Yes, I can get it with 4 or 5 bolt exhaust exit flange and a T04E compressor cover.. so it will fit any manifold that accomodates a T3/T04E. Email me at Travis_311@yahoo.com if you want one.

it wont fit. trust me, i know. if you have a 5 bolt manifold, get a 5 bolt. if you get a 4 bolt, it will hit the head/valve cover, and you will have to grind about 1/4-1/2" off of it, not fun.

if you have a 4 bolt manifold, it would put a 5 bolt turbo too far away, possibly hitting the radiator support, i am not 100% sure.

Well.. of course a manifold made for a 4 bolt T3/T04E isn't going to work.. but the Protech mani, my company's mani, and any other manifold that's designed to fit a 5 bolt T3/T04E will fit this turbo with no problems.
