I have a 420a that im going to build my own kit. Idont know a whole lot as far as what kind of turbo is best, so Im asking you guys.
I've been hearing some stuff about a garret T3. Where does one find this turbo for cheap, preferably not ebay. Does anybody have one for sale????

 

i know that the 16g actually works pretty well with that car too. I think thats the turbo that the hahn turbo kit uses

 

the Garetts are good up to 1000 HP..was watching NOPI TUnervision and this sick civic had a garret something something turbo.. i mean a big *** turbo

 

that is very general statement there. There are alot of garretts and almost all of them are not good over 800hp. Even the very biggest ones probably wont get 1000hp. even the 42r is only good till around 850hp. I think the only one that gives that is the GT60

 

for what your doing your would be best to buy a used t25 or a rebuilt t25, If you want you can get a 16g which is also good for the 420a, its got a little bit slower spool time but its a'ight. If you want a new turbo look for a t3 thats got something in the area of a .40-.50 a/r.

 

big 16g was great for me until i moved to the SCM-61, i still have it and it has no shaft play and only 400 miles on it...lemme know, i have pics of it

 

how much you asking? Slow420a, what does .40-.50 a/r mean??? lol

 

It is the turbine housing sizing. Basically the A=area of the turbine housing and the R=length from the center of the turbine housing to the shaft.

The reason you have to specify this is because T3 is very general, there are many different types. Varying by a/r ratios. He is saying to use one in this range is because if you try and use a bigger a/r then your car wont produce enough air to spool the turbo.

>a/r = more area therefore more lag but more power potential
<a/r = less area therefore less lag but less power potential

 

ok...thanks guys for all your help. Im sure you guys see this and say to yourself "are you kinding me" but I dont know anything about turbos besides the basics of how they work.

 

nah stuff like the a/r alot of people dont know about. I actually had to re-look it up to remind myself exactly what it was. I had an idea but remembering details is always tough. And no one knows it all, and none of us are experts. So no question is stupid
