What turbo!!!

[nab911]

Ok, i have thinking for a while what turbo to put on my motor. I need it to be rated to AT LEAST 350 hp because im not payign a lot to have somethign i need to replace later. Next, i dont want to be spooling around 9500 cause lets face it, i will shift befor then . I have been looking at a t3/t04e but ill be at full boost at like 4k. I want a garrett gt series turbo but im not bill gates. Ide like to spend at most 500 for the turbo and 200 for a manifold for the beast. And anyone here know where i can get a manifold for a tx or gtx series turbo?

Im gonna have a HKS dual Ball bearing bolt on turbo for sale soon, Bolts up just like stock makes 350 or more wheel with a good srtup and spools bad ***. Its a 2540, I want it but I dont need it right now

One of my son's stumbles across a place in Huachuca City, AZ called Speed Factor Designs . Looks like their prices aren't bad. I have no experience with them but they seem pretty serious. Click on the Turbos and Accessories link.

Im getting a T3/T04E 50 trim with .48 back housing.

Its the one that Dee also uses.

Its in its efficiency range (78%) from 10-20 psi and Dee says it hits full boost around 3200. Even at 25 psi its still efficient.

I did my homework and its well suited to this motor.

prices look decent. has anyone by chance had experience with these people or perhaps know a little more about them?

**GT25R w/ .63 turbine, ~$1000 from cheapturbo.comT3/T04E (50T w/ .48 turbine) ~$600 from cheapturbo.com

** i would reccomend this, you can use your OE manifold and SR DP and O2 pipe.

Quote »T3/T04E (50T w/ .48 turbine) ~$600 from cheapturbo.com[/quote] I actually can get these for around $450ish and they get the job done and nicely for the most part. But, if you got money to burn and want to try ballbearing units, go for it. They are sweet and a treat to have, but when they go, you're owned!:tisk: :owned

[Foreva180]

will a t3/60-1 be efficient?? they are about 200 more, but they are also a bigger turbo..... any suggestions?

[PacManVR4]

It takes alot of boost to make a 60-1 happy, Your not gonna get there on the street. You will be very happy with a 50 or 57 trim t3/t4 with a stg 3 wheel and .48 or .63 with a to4e comp housing. Bigger isnt always better.

[nab911]

Wow, not a single person told me to search Im not clear on the trim thing other than i know the higher the trim the later the spool but the more power you get. What will the full boost be at for a gt25r and a t3/t04e with 50 trim and .48 turbine? I dont care about in the mid to high 2k's and 3200 isnt horrible but the lower the better.

[Nismo1182]

My friends SR20DET with a GT25R with the big back housing spools fully around 4400. Dee has the T3T04E 50 trim with .48 back and he says full boost by 3200.

[nab911]

wow... way too high. How big of a back housing? What does the gt25 with a .63 get full boost at?

[Nismo1182]

The GT25R? Theres 2 optional back housings for it. the smaller one spools around 3800.

[nab911]

?? I thought they spooled really low... A friend of mine says a gt28r will spool around 3400... which is about the same as the t3/t04e but which one would make more power?

[nab911]

Is it possible for me to get a turbo good for 350 hp and spool below 3k? And is this going to cost me a testicle?

[Nismo1182]

That bolts on? An S15 turbo is good for about 300. The T3/T4 combo im going to use is perfect though and only $450. Downside is youll need a new manifold and ex.t wastegate. But its all upgrades anyway.

Quote »It takes alot of boost to make a 60-1 happy, Your not gonna get there on the street.[/quote] You're right, a T3/T04E stage III 60-1 will give you major lag on the streets and even on the track and this I can vouch for. I own a 60-1 and the .63 backhousing and I'll be honest, it made it very hard for me to race from a dead start.

I mean even between gearshifts, the car was dead on it's face until the boost came on. But I figure with the bigger camshafts, higher compression and better flowing manifolds, I'll try it again since my 60-1 has been redone fresh, though nothing was wrong with it.

My thing is, until you've driven a CA18 powered vehicle with various turbos in them, you can't really say which is best. What may be good for one, may be crap for someone else. I'm 110% sure that a T3/T04B or E stage I-V will provide excellent driveability on the street or strip.

I think the important question is what are you wanting to do with this car? For me, I autocross, so I need a wide powerband (quick spooling) and gobs of power isn't as much of a concern because I won't need it. I'm probally going to use either an S15 turbo or a skyline unit and keep the boost at around 12psi, maybe less. But I'm also going to build (or try anyway) and equal length exhaust mani to help that spool out. But that is for me. If you are more into street racing/road racing/drag racing, then my setup may not work well for you.

[boost_boy]

Believe it or not, this engine doesn't need a whole lot of turbo like some may think. And contrary to what some may think or over-heard, ain't no sunshine with the CA18DET until after 3000rpm; so if you're looking for something to spool-up under 3000rpm, should've bought an SR or boosted a KA. The RB series brings the same attitude; nothing but a nice car to drive around under 3000rpm and off boost. Who wants to drive around on boost all the time? Sucks for gas mileage and will increase the wear in components. But for auto-x-ing, an S15's turbo will serve this engine very well.

Yea! I'm not as dumb as I thought.

Sounds like you might have the wrong engine. It'll be virtually impossible to find a turbo that can spool up that quickly and still provide enough airflow to support 350hp on a 1.8 liter engine. The cool thing about CA's is that you can put a bigger turbo on there that might take until 4k to get fully spooled but still have a good honest 3-3.5k rpm power band with full boost...that's kinda cool I have much love for the CA's, it just seems your asking for the impossible.

[float_6969]

^^^ what he said. If you're wanting that kind of power with that kind of spool time I would SERIOUSLY look at a turbo KA. They are about the only motor that has the displacment to get it to spool that quick. Plus you'd still be fairly streetable.

[boost_boy]

And we talk about expectations:rolleyes ! Anything past 3700rpm is going to be a good contest between the CA and the SR, but the KA kicks 'em both in their puny ***es. Get 'em all past 4000 and the playing field gets a bit more leveled. But from 850rpm to 3500rpm, the SR and the KA owns the CA and I strongly recommend these for street racers who like to hear BOVs at 1500rpm and like their power too early. When these two are all puffed-out, the CA just smiles and keeps on humpin' past them.

[Nathan]

Indeed, we are dead after 6k The engine will take a crap if you even try to rev anywhere near 8k with any regularity...but we have nice low end power, good driveability, it's all about what you want from the car. (I speak of me and my fellow KAT'ers)

(I speak of me and my fellow KAT'ers)[/quote] Hey Nathan, most of my boys are KATers as well and please don't let me here what I see happening to their motors (Pop goes the weasel). Their chasing big HP and I think to date the highest is 487whp@28psi on a stock KA before it blew up. I'm sick of looking at the insides of those motors, so keep your together and remember "Expectations";) .

[Nathan]

Haha, I'll try D...at least it's not stock (pauter rods, ross pistons) and I'm not chasing anything too crazy, just have to hit at least 350whp once Sometime Korey's going to HAVE to take me for a ride in his car, I've been looking forward to it for a while!

[boost_boy]

Ahh, you'll see 350 with not too much drama. Speaking of Korey, I have to get those gaskets for his turbo.

S14 BB T28 for me!

I can't find a banging tubular manifold for any other turbo, plus this will suit me just fine. Nice little street turbo that could possibly get me deep into the 13's if I take it to the track. I've got a few other parts to order yet, so it won't go on until the Spring when I repull the motor to change the turbo, headgasket, clutch, injectors, and clean up the motor and my sloppy wiring. Hoping for close to 300 to the wheels with it and my other mods.

Yeah ya do, then he can bring it over and we can have an evening of gasket changing fun

[Foreva180]

i read through the whole post and didn't find this, but what about 60 trim with .63 a/r.. is that going to be too big too??
