Aftermarket Garrett T3

[s13silady]

i used a search...needed something simple answered that search couldnt help me out with...

just wanted to know... if a T3 would be good enough to reach my 280-300 hp goals...
and if it is possible to run a little tiny bit faster than a 13 sec 1/4 time with a T3 <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/blush.gif" border="0" valign="absmiddle" alt=':blush:'>

Breaking any car into 12 seconds is hard, wether it is a GST, ITR, 240sx, or a civic. &nbsp;A t3 is used on the older 300zx's, and only produce 220hp at 7psi. &nbsp;Then the turbo will die off at 14psi (for that engine/turbo combo.) &nbsp;A t3 may get you at the right horsepower, but as far as speed, there is a lot of work to do. &nbsp;PSI240sx has 390rwhp, and ran a 12.5 in the 1/4. &nbsp;

This guy, built KA on a T3 ran a 13 flat. This was on crappy 6.5" street tires. Some drag radials and he woulda been in the 12's. Forget what he said his hp was though.

Hope this helps

i mean im not looking for a straight up drag car.... but will a t3 be good enough to push the 2.4 litre motor?
this is also gonna be daily driven...
and since the 300zx's were six's a t3 would do better on a inline 4 wouldnt it?
what PSI's are t3 good up to..?
when will it spool and will it keep spooling until redline?
im kinda on a budget so ill have to do with the t3 for now...

hey PSI240sx, what turbo are you running? can you give any feed back on running a T3?
thanks again

Jay's running a Garrett T3/T04E.
As far as the a t3...I think they are usually out of efficency range at about 14 psi. &nbsp;The t3 would perform better on an inline four as opposed to the v6 on the 300zx's. &nbsp;As far as spool times, it depends mostly on the exhaust housing. &nbsp;The larger the A/R the more CFM it will flow, and the more lag it will have. &nbsp;T3's have all different types of customizeable exhaust housings. &nbsp;How much boost are you planning on running?

I thought that I answered most of these 2nd questions. &nbsp;Usually crap out at 14 psi. &nbsp;If it was on the 3.0L motor in the 300zx, it will work on a 2.4L motor, and spool much faster, becuse you have nearly 1L more exhaust gases in the 4-cyl.
Yes, the housings are interchangeable, as are the turbine wheels, but once you start buying 2 housing ($300) and a couple wheels ($500).. well. &nbsp;That's friggin expensive. &nbsp;PSI240sx doesn't usually post here. &nbsp;
Along with the aforementioned links, read Maximum Boost by Corky Bell, and visit our FAQ section. &nbsp;I just moved a great turbo sizing and general info post to there.

ok so your telling me that i cant push the turbo more than 14 psi???

i didnt plan on running more than 12 or 13 psi...

[Tyler Durdan]

You can go beyond 14psi, but it's pretty much out of efficency range. If you are gonna go higher than 14, I would suggest upgrading to a t3/t04. I'll run some numbers on the t3 at 12psi, but can't gurantee anything.

Edit: What's the exhuast housing size on your t3?

[DarkRaptor42]

This seems like a good time to ask my question on T3s. Jeff mentioned that the T3s are pretty interchangable, so my question is, If I found a T4 and pulled the compressor housing off of it, could I strap it on my T3 and have a t3/t4 that way? To be honest I have only seen one t4 and didnt get a chance to look at it very well but figured that I could do that swap. Am I right?

[s13silady]

you could do it that way technically but then you would need to get blades that fit the compressor... and you wanna make sure the trims are right....
i think thats all... but im pretty sure theres a little more to it that jeff can clarify...

by the way.... you stole my post.... &nbsp;haha just playin.. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt=''>

[Jeff240sx]

Back to post stealing. &nbsp;I haven't done that, but I know it is entirely possible. &nbsp;It would be a lot of figuring it out yourself. &nbsp;You would need to match the blades correctly, and the housing correctly. &nbsp;But yea. &nbsp;It happens. &nbsp;And to find t4's, look in Diesel (sp) trucks for them. &nbsp;They will have huge exhaust sides, but probably a usable intake housing.

Well my question acctually arose from The page that jeff posted. You can by new blade wheels and compressors for about 120 a peice. Seems like a damn easy way to go t3/t4. I think thats what Im gonna do after I get the rest of my stuff.... Almost there too...
