I want to put a single turbo on my LQ4 that will be going into my 71 skylark. I have been looking at turbonetics hurrican series 78mm, they run about $800. Is the turbonetics a good turbo or is there a better turbo for around the same price?

 

There are better choices but they cost more unless you buy used. Also, you can get one for a lot cheaper than $800...see Huron Speed

 

Id go with a brog S475 if you have room. Not too impressed with Tnetics right now..

 

Really depends on your goals, but for a stock LQ4 looking for 500-600hp, the TC78 would be a great choice. Turbonetics also offers a 1-year hassle-free warranty. I personally haven't been anything but impressed with their service either. If you want a little bit more bad to the bone turbo with a few more options available, higher HP rating, I would go no where else but Comp. However you are going to pay about double.

I currently have a TC78 on the shelf, no wait or build time, if you are interested and can get you the best pricing of anywhere if interested! Let me know!

Tc78 is an excellent turbo, tnetics has good cust serv. Quality parts.
I like that turbo alot for street duty, also there evolution 38mm wg is quality also.
I use tnetics for just bout everything now.

 

I just bought a tc78 from Huron/Superman and the price was great !

Even though its listed @ 900+ turbo I think it's just a bit small for that.

If I can get 650-700 out of it on a 4.8 ill be ecstatic !

 

Thanks for the feed back. I would like to get about 550-600rwhp with a TU1 cam and this turbo.

 

No problem!

 

I just ordered the same cam !

 

I'm getting about 700whp out of one one a forged 346. They are good turbos but if you are lookin for more I'd go with a pt7675. The tc78 has a smaller 68mm turbine wheel and is showing to be a restriction on my setup.

 

how much boost are you running?

 

what he said^

 

Im running a turbonetics t76 with the 68mm turbine wheel @ 12#'s I'm at 629rwhp and 640ftlbs engine is a lq4.

 

My tc78 started it all for me!
If you want 600rwhp its great, on a 5.3 i think they are about perfect.

 

I have a pre order on a tc78 with the new f75 wheel....cant wait for results! my buddy will be running it....for get the dudes name but he told me mid november!!! cant wat to see how it stacks up to the precisions.

Ive hand nothing but crazy good results wit the pt7675s....so im dieing to see dyno results side by side!

 

They are coming out with the 75mm wheel, but it is still delayed another month or so now. I will be able to get them for everyone as well! However my rep informed me they will only be released in Ball Bearing so pricing will be a bit higher. If it is the same as their current TC76/78 BB prices, it would be around $1100

 

That's at about 17.5psi but I taper really bad up top.

 

I was told the same thing from Turbonetics, only available in BB.

I called to ask about larger A/R's on the exhaust side and she asked me if I would be interested in a larger turbine wheel- I said of course- she then mentioned It would be only BB and "should be out" in a month or so. this was last month of course.

 

Yep, it will be a nice unit for sure, but it will be in direct competition with a Precision 7675 and Comp 7879 in that price range. As of last week I was told another month or so. The Precision 7675 looks about $1400 in Journal, The Turbonetics will be about $1100 in BB, and a Comp 7879 is $1579 BB and Billet.

 

How much more improved over a standard tc78 for the new bb versions?
