Turbo upgrade

[CA19DET]

I dont have a 60 Trim T3/T04E, i have the 50 Trim which spools consideralby better because of the smaller compressor wheel and housing.

i tried to sell my T3/T04E 50 Trim to get eh GT25R, i think i offered it up here a couple times, but it didnt make sense shipping to the states and no one locally wanted to buy it, i bought it over a year and a half ago when the GT series wasnt even heard of yet. i would love to get a GT series turbo, want to buy it for me?? i know i'll have one in the future on some motor i build next.

and the stage 5 T31 turbine does take a considerably longer to spool, but my T31 Stage 3 should make full boost where i need it, and if it is 3800, 4200, 4500rpm, really, thats full boost, it's still making 60-80% of the power from 3600rpm anyway, and it will help with traction.

i still know that garrett and HKS and other turbo designers and engineers are right, and are making better turbos for the future...

Compressor maps are the correct way to choose a turbos not racing at 160mhp. and it is unfortunate that i dont have more hands on experiance with these GT turbos and other turbos, honestly i wish i did... but i do listen to tuners that do (secret services, enjunku and others)

but anyway,,, i am sure this topic is boreing by now, and we have confused too many to make any sensible decision when it comes to turbos. and in the end your decision would be as good as ours.

i know the reason i am so passionate about this turbo tech stuff, is cause i have been involved in so many debates on the T vs GT thing, and its always come out that the T boys make plenty power, but the GT boys are making the same power, more efficently (less turbine effort and compressor lag) in a more compact modern turbo... thats all..

Tim,

You have to do what's right for you and that's most important. The reason why people go for a custom header manifold is for better flow characteristics over the stack manifold, hence the reason why CA19DET has a custom header and not the stock manifold with GT series turbo. The stock manifold is worthless for high performance, but will assist you enroute to a 300+hp car. I know this because I had aT3 flange welded to my stock manifold with a T3/T04B and it worked (leaking) until I hit that pole. Anyways man, good luck on your pursuit of power! Everyone has a different view and are entitled to them, I just speak from my experiences with what parts I use, not what I read on the net or in a magazine. I'm sure that because I'm trying to exceed 500whp, I will probably end up using some big turbo that I would never take to the track. If you're not using nitrous on this motor, then a big turbo is not the way to go for fun. If you don't like your power coming on in the 4 and 5000rpm range, then you do not need a T3/T4 or any big turbo upgrade. Just high flow your T25 and roll-out.

[boost_boy]

Honestly Aaron, would you stick a precious GT turbo on the stock CA18DET manifold? I wouldn't! I would spend the money to get a nice manifold made, so I don't get robbed of power and flow.

[CA19DET]

honestly i would, if i were on a budget build and knew i would upgrade to one in the future, sure,

i always thought the GT25R on a Yashio factory manifold would be the Hot Sauce.. the yashio factory manifold is desiged for these GT series turbos. but hey thats allot ching ching ching for some bling bling bling... but thats an awsome combo..

[boost_boy]

The stock manifold is garbage compared anything else. But hey, if the flow is low, you'll have to settle for the low flow of the stocker unit. I got rid of the header manifold for a funky log style and I'll tell you this, it pushes that 60-1 nicely. The car comes onto boost considerably authoritative, yet smooth. I used to use it with the stock manifold and welded t3 flange and that thing was laggy as can be. Full power was really close to 6000rpm, but at least it came on. I know a guy that used the same 60-1 turbo with .63 rear housing and his 4AGZE would not spool up until 7200rpm and he hated it.

just wanted to add this to the SR vs CA battle and using a SR as a comparrison to CA for turbo testing >>

dont forget the great equalizer!!! RPM!! LOL.

ok, here's the real deal. In a world of ideals TQ is directly related to displacement. this we all know so in theory the CA should make 90% of the TQ of the SR. now this is all theory as we know that bore/stroke and cylinder head design can (and do) all have real effects on the TQ generated by the engine. but for the simplicity of this arguement lets say that the two engines in quesiton are close enough so that these differences balance out.

now you're probably askign yourself why i'm babling on about TQ when the question at hand is HP? lets ask ourselves what the one distinct advantage the CA has over the SR (other than iron block)....RPM! what links TQ and HP?...RPM (and a constant). So lets say you have an SR that is making 400whp @ 7300 RPM (and is on the verge of chucking its rocker arms ). this would require 288 ft-lbs at 7300 rpm. now we can accept the overgeneralized assumption from before that the CA would make 90% of this TQ. so we would have 260 ft-lbs of TQ at 7300. but what if we can maintain that TQ to a higher rpm? well at 8080 rpm with only 260 ft-lbs of TQ the CA would also make 400 whp.

remember. if you are goign to start comparing mildly built engines..at least rememebr to take into account the strong and weak points of each engine.

THIS is where people get confused. You start talking about HP being a function of TQ and I usually get a lot of blank stares...

I think I'm just gonna go with either the Pulsar T28 from CheapTurbo or the GT28. Not planning to push the limits of a CA.

Is there anyone with CAs running mid 13s at least?? What mods??

[boost_boy]

You can run mid 13's with the stock t25 at or around 10psi! the key is getting off the line on time and making sure you have the right shoes on your car as well as VLSD. Too much power off the line and you'll be burning up tires like i smoked my fresh drag radials and got the rubber all over the new paint job.

[GotBoost4Yall]

In a s13? I know you have a Sentra, is there a weight difference??

[boost_boy]

I'm referring to an S13!

13's in a CA is easy. Even with bad rings and a leaking exhaust mani, I'm pretty sure I could pull a 13 right now. It would he a high 13, but a 13 nonetheless. It's all about the launch. You've gotta let the clutch slip. It's hard as heck on it, and if you do it all the time you'll go through clutches like mad, but it gets you down the track fast, and my RT's are pretty low too...

Only because they're covered in Salt....

And now Mr. Nuts is meditating *:rolleyes *

good lord. i cant even remember what this thread started out discussing! oh well, i guess its for the better.

Mr. Nuts is "so low to the flo' like the pocket of a miget". which is pretty damn low.

Dee, why don't you "meditate" on your own time. If you want to get a better grip on your man-to-hand relationship, that's fine, but I wouldn't tell Rosy Palm and her Five Sisters about it, alright? Hehehehe

[r34 gtr]

i prefer palmela handerson.

First of all, congratulations to us for getting another thread completely off topic. Secondly, all I have to say is Zena, Warrior Princess. I like girls than can kick my arse!

ryan, she told me she still wants her $2 for last time you whore! i aint letting this one slide!

my mom seems a little short to be zena, she's 5 feet, even. and dee, im sorry if i cant seem to bring myself to agree with your claim that she's hot, even though im from alabama i dont really check out my mom. i tell ya though, if i had a sister...

Tell ya what, I'm gonna kill you both. Then I'm gonna kill myself and chase you guys through hell!!! OK, so maybe not, but it's kinda scary, isn't it? Oh wait, tall skinny white guy with blonde hair and blue eyes is probabally not the most intimidating thing the in the world is it? Dangit, back to the drawing board...
