SIMPLE for you all.....selection questions
So I'm thinking of going turbo with my D16y8 in a 89 Si hatch.
Im curious to know if the T3 is a good start turbo for stock internals? Which t3 would be best for me the 42/48 or the 60/48? What are the stock psi on those turbos? Should I go to the 14b? Whats the stock psi on the 14b? What diameter charge pipes should I run? Thanks for the help guys |
Re:SIMPLE for you all.....selection questions
go w/ the 14b if ur gonna keep stock internals.... it spools fast..... internal wg set @ 10 psi (fully open)
built block.... t3 48/60 or t3/4 |

Re:SIMPLE for you all.....selection questions
isnt it set at 8psi, not 10!? anyways, get the T3 42/48. that what i got in my d16a6 and it just rips the tires loose once boost hits, even cruising in 2nd!! i think my wheel trim is bigger than the regular saab/volvo t3's. either way, i think its a very good turbo for the D!! mine has very slight lag and then BOOM, that ---- just rips loose! i love it ;D

Re:SIMPLE for you all.....selection questions
Where did you get your manifold and downpipe?
What size charge pipes are you running? Any hp/tq #? Thanks man |
Re:SIMPLE for you all.....selection questions
get a t3 42/48
|
Re:SIMPLE for you all.....selection questions
t3 42/48 seems to be the leader.
Where might i be able to purchase an adapter plate for the t3 to use with the STD manifold? |
Re:SIMPLE for you all.....selection questions
isnt it set at 8psi, not 10!? anyways, OMG... not this again!!!!! ok... i tested the wastegate on the turbo w/ compressed air w/ a regulator and a gauge... it starts to open at 8 and is fully open at 10. for the adapter plate.... BMC sticky in the for sale section has them.... good quality! mike |
Re:SIMPLE for you all.....selection questions
in your opion is 10 psi to much to run on stock internals
i will have injectors, fuel pump, fpr, hondata |
Re:SIMPLE for you all.....selection questions
run it... if your unsure about 10 psi you could alwas get a different WG w/ a lower psi rating!
if u got hondata.... i wouldn't worry bout it... just tune the hell out of it! mike |
Re:SIMPLE for you all.....selection questions
are all t3 the same as far as bolt ups regardless of what car it came off of.
as well are they all the same specs the .42/.48 that is regardless of vehicle they came on? |
Re:SIMPLE for you all.....selection questions
one of the t3's has a fucked up four bolt flange pattern, but as long as you see a pic of it before you buy it, you will see, it's not a perfect rectangle like reg t3 flanges, it has one bolt hole that is out of whack, other than that, yeah, all t3's have the same 4 bolt flange and there are a couple different styles of dp flanges for them too, but the most common is the 5 bolt (although there's two different 5 bolt patterns, one is more common than the other). a .42/.48 will be a good choice for you, especially with hondata, fuel pump, etc., you'll be able to run 10 psi safely all day as long as you have your hondata tuned. now that i confused the hell out of you, good luck ;D

Re:SIMPLE for you all.....selection questions
10 psi with uberdata or any ecu fuel managment, you should be fine! my downpipe was custom made at a muffler shop and my piping is about 2in the it goes to 2.5in right after the intercooler. havent got to dyno yet though. projekteg said it good, there are many t3's but most have the same four bolt pattern execpt one ugly ducking thats a bit different. some also come 42/48, 60/48, and 63/60. but the 42/48 should be about perfect!

Re:SIMPLE for you all.....selection questions
the ugly duckling y6ou are referring to are from daytonas and lebarons (tbo335)... AR is 42/48 on them... same as reg t-3's
:D mike |
Re:SIMPLE for you all.....selection questions
Don't be scared of 10 pounds of boost. Treat your motor like your bitch, your gonna give it 10 pounds and its going to take 10 pounds and its gonna like it. This is my philosophy and its been working for years.

Re:SIMPLE for you all.....selection questions
yeah like whitey said... i treat my bitches like whitey's engine, douple penatration.... ive been doing it for years and they love it! ;D

Re:SIMPLE for you all.....selection questions
LOL good attitude

You crack me up. 10psi it is then Gentlemen you guys ROCK |

"max boost" by corky bell states that cracking pressure is generally 1/3 to 1/2 full boost pressure. (that's where all these equations are coming from, in case you're wondering) FS= 9.82lbs so FH+FD=9.8lbs FH= 2PI*AH= 2PI*0.994 FD= PI*AD= PI*1.227 so (PI*1.227)+(2PI*0.994)=9.82 solve for PI and we get ~3psi as our cracking pressure. which means our max boost with that wastegate is between 6-9psi. these numbers would be more accurate if someone could measure the wg canister diamter and the diameter of the wastegate hole and plug their areas into the formula (remember A=pi*r^2). point is, what boost the WG is set at is not as simple as measuring the pressure needed to open it on a bench. |

ummmmmmmm...........
ok! ::) mike |
