my motor is out and is getting ported,pinned and balanced now i'm very confused with the turbo set up i have no idea what to go with maybe you guys can give me a hand or point me to the right direction. i want to put down 500 to 600 whp no less this is not my daily driver but i usually like to drive this car every other day for a cruise.. thanks for the help fellas.

 

Buy my GT42R for $1100 and you can make 700+ My new GT4208 80mm came today

 

My t04s costed 1200. :/ I guess that's what I get.

 

Mine has a brand new cartridge too

 

what rpm does your turbo starts spooling? 6k?

 

God no, I hit full boost at 4500ish. It starts building much sooner. It depends on your porting and tune as well.

 

GT42, the one ernieT has is a good deal. I have the GT4294 with a huge port and start to spool at like 2600rpms and 1bar ofboost at about 3800-4000.

 

Bw 372. best Efficiency

 

i also want something that is going to last

 

well thats going to depend on you, Garett is a great brand but it is still dependent on you, take care of it and your engine and it should last. but on the same token i just had to rebuild mine after 10k, i would recommend going with the journal bearing, i notice no real difference from the ball bearing, but thats just me, also it cost half the price to rebuild if you need it.

 

Precision pt74 or pt76 gts turbo. Great turbos

 

i was actually looking at the gts 74 and 76.. but now ernie and azcamel got me interested in the gt42..ahh! decision.. decisions..

 

I was going to get the 74, but after speaking to someone on this forum, I went with the 76 because I felt it was best suited for my application, which is drag.

I've heard good things about the 74 but can't elaborate because I don't have first hand experience, but i can tell you that I LOVE my 76. Top end for DAYS..... It all depends on what you want... I high HP Street or strip car or a street and auto x car. AT some point it's going to become one or the other.

I hit full boost in the 4000+ish range with the 76GTS, the 74 would obviously spool a little faster.

What I also liked about some of the Precision turbos are that they are almost identical in size. I had the precision GT4067 which is now the pt6776(Great turbo BTW), swap in the pt76 with minor mods.

BTW: those two other turbos are great turbos too. They'll get you where you want to go.

 

FYI,
I made 641rwhp @ 20lbs of boost. Not many turbo's can do that.

 

I would go with the SC366. It's a very nice street turbo. You're capable of making 600whp and the Borg Warner turbos are extremely durable. I had the Borg Warner SC362 and now have a 42r. I we're talking double the cost with the 42r. Oh by the way, I just started up my new 42r last week and it was DUMPING oil out the turbine housing (dripping twice a second) and a slight drain from behind the compressor wheel. If they don't offer a free rebuild you'll be seeing a new thread from me...

 

do the ball bearing gt turbos require an oil restrictor? Did you have one?

 

Again, as noted before, your results will vary depending on port and tuning of your motor, So you might not have the same results.

 

He said 500 - 600 hp.....ur numbers are a bust then haha....j/k Good numbers though.

I would suggest a T04Z because that's what I have and I make 462 rwhp at 18 psi.

 

A street port will net approx. 70rwhp less. Yes it requres an oil restricter. I have had NO problems what so ever with my GT42R. Only reason I bought a new cartridge is when I blew a motor an apex seal chipped a wheel. And I don't like to half *** things so I just brought a brand new one. So you get a $2200 turbo for half price. Nothing will touch it.

 

Yes they do, I had one in my setup. It was a .065" fitting. I actually just made a post in another thread about sizing properly an oil restrictor for BB turbos and journal bearing turbos.

 

woah that sucks dude

FYI,
I made 641rwhp @ 20lbs of boost. Not many turbo's can do that.

was that on q116 or pump gas?

 

Ernie doesn't play with pump fuel. It was c116 or possibly the "Q" series. As for my problems hopefully Garrett stands up and doesn't make it "suck."

 

i guess i'll have to flip a coin.. any other turbo besides the gts74,76 and gt42?

 

I think the BorgWarner S372 and up turbos are becoming popular too. And there are some Holset(sp?) turbos out there making big power. I think someone on the forum has one making big power too.

 

What kind of fuel do you plan on using?
