Just wondering which one of these turbos would be best if I was shooting for around 400hp, while maintaining the best torque possible. Has anybody even used the gt35? I know they've used the gt35/40 and all that but what exactly is that difference? Thanks in advance.

 

if you are looking for a cheap turbo get the "blowzilla" from cheapturbo.com. torque will be a function of the horsepower and rpm so dont worry about that.

 

Is that "blowzilla" the same as the gt35/40's? I was actually checking this one out and also the t04r "Big Kahuna" on cheapturbo.com

I appreciate the input

 

The GT35/40 and GT35R are the exact same turbo.
The "Blowzilla" is a GT35 compressor side with a T04 hotside instead of the T3 side.
The T04R "Big Kahuna" would be more than what you are looking for. It will easily give you 400rwhp, but that's not even in it's efficient or "sweet" spot. I would recommend the GT35R(GT35/40) for what you are looking for. The only reason I am saying that over the "Blowzilla" is because I haven't seen any dyno graphs from that turbo. Nor have I talked to anyone who has been running it for a while. But I do know that cheapturbo.com seems to always take very very good care of their customers. So it's up to you on that one. Hope that helps you out some. Also, you could look at the Apex'i RX-6 turbo kit. That would put you at your goal with really good torque numbers as well. PM me if I can be of any help. Laterz.

he is putting a kit together so the rx6 is out. a 35r can be had for around $1250 and will do exactly what you want. a quick 400whp. my car will be done in about a week or 2 and you can ride in it. that way you can feel the rath of the r85

 

The Blowzilla uses a GT35R compressor, not a GT35; the GT35 is smaller than the GT35R. With a properly set up car the t04s will make 400rwhp at around 14.5-16lbs of boost. The T04s flows 61lbs/min and the 35R is rated at 65lbs/min. Also, the 35R is more efficient than the t04s and the surge line is in a better zone for rotaries (based on my math anyway).

Therefore, the 35R compressor should be capable of producing slightly more hp than the t04s at the same boost level. However, judging from the GT3540 dyno results I have seen, I don't think the difference between the t04s and 35R compressors will be significant.

Compressor maps are available from Garrett at http://www.turbobygarrett.com/turbo...t/jsp/index.jsp

From the results we have seen the GT3540 does not make anymore power than the TO4S.

Why don't you browse my dyno page at http://www.catenet.net/dyno.php and check out a few actual results?

Thank you for the correction of the GT35 vs. GT35R. I knew something didn't look right with that post. You just got a "Blowzilla" didn't you?? I thought I remembered seeing something with your name on it either on this forum or nopistons. Either way, make sure keep us updated on how you like it once it's in and tuned. Laterz.

Hi Zach,

I have a blowzilla sitting on my coffee table at the moment I am planning on installing it sometime next week. I started a thread on this forum and the other forum, but ultimately ended up just using the other forum because I was not able to upload pictures here and have no place to host them. I will definately post my dyno results on both forums once it is tuned.

 

But the turbo in question is neither the gt35/40 or the gt35r, its just a plain gt35. On cheapturbo.com I see no listing as the "blowzilla" being anything other than the gt35. Is it still the same turbo?

I think all of this answered my question though. Thanks

I may have to take you up on that offer. I rode in Jim Swantko's old t78 fd. Do you think thats similar at all?

 

One other question... what would be a recommended size wastegate for this set-up? The gt35 that is.

 

Allrotor93's car would be faster and much more powerful than a T78 from what I gather. Especially with the right porting and tuning!

A Tial 38mm gate would work just fine for a GT35. I don't see any need in running a bigger gate for the HP you want.
