hey im in the market for a new turbo. i like the idea of the 4082. i was looking at the compressor cover and it appears to have a vband for the intercooler pipe. does anyone have any pictures of this setup on their car or just describe how you have it setup

 

[Jimmysmk3]

anyone?

You have pics ? The intercooler pipes need to flex you know .

About the 4082 - IMO the gt40 exhaust is too big (mismatched) for the 4082 compressor . If you only want 500hp , get a 500hp exhaust wheel such as stage 5 or gt35 ex. wheel , otherwise you are just buying lag .

from what i understand the 4082 is a very fast spooling turbo.

here is a pic.

If you're looking for "very" fast , most recommend the gt35r . Its has a smaller exhaust wheel , but still flows more air than the 4082 .

Here Aaron's 4082 dyno and BTW and i think there is a few more dynos with that turbo floating around .

im looking for a t4 footprint and the 35r is a little out of my price range. im either looking for the 4082 or the 4088 im not 100% dead set on either. my question at hand is that on the 4082 does the compressor outlet need a vband coupler? it appears to but i want to double check with someone who might know.

If i were to do it all over again, I'd get a s366 from here http://www.bullseyepower.com/S300.asp
I ended up first getting a precision 61mm which spooled FAST and pulled hard. I don't really care about spool that much and ive ditched that turbo and my master power t70 arrives on monday. This 70mm turbo will better suit my needs. I think Logan is right though, the 4088 looks like a turbo that was made to work together, while the 4082 has too small of a compressor wheel. For 500hp look into the jt series bolt-ons. They will spool real fast and you won't have to worry about a dp and external. good luck

i looked into that turbo and it also seems very pricey for a 66mm. i was also looking into the master power line of turbos. they seem to be very good for the money, ive also noticed a lot of mustang owners using them without any problems. maybe i will look into the t70 as well.

gt4082 and gt4088 are very different in size. the 4088 is much larger. and yes, the 4082 has a v-band outlet on the compressor. the 4088 is a standard slip fit.

you may consider the pt61 like gilberjj was running. it is real similar to a gt35r, just not ball bearing. those are a good bang for the buck at $749. the gt40s (4082/4088) are still a good deal at $815 but parts from garrett have been on backorder frequently.

 

[Jimmysmk3]

i used a pt63 on my car previously and i liked it but i want something a little more and for the price of the 4088 it seems like you cant beat it. unless im missing something and the pt61 puts out around the same amount of power with quicker spool? it seems like everything is pointing towards 4088 so far.

 

[dbsupra90]

the 4088 is bigger than the pt61 or the pt63. its a 64.5mm inducer and 88mm exducer. the turbine wheel is bigger than a p trim as well. it doesnt spool as fast as the 61/63 but it will make more power.

for good spool and 650+rw capable, the best deal is the pt67bb. its a steal at $1120, but sounds like you are looking to keep it under the $1000 mark.

 

[Jimmysmk3]

yes i am i was trying to get something for under 900 shipped. what do you think the pt61 could make at 20 psi on a stock engine? with supporting mods of course.

 

[dbsupra90]

with a good tune 20psi usually 500rw range. ive seen anywhere from 460-540rw with 18-22psi. ive even seen over 600rw with it, but on a 2j (higher than 20psi tho).

with the pt61 on my car i did a baseline and made 360rw at 10.5psi untuned. i wanted to see what it would do at higher boost but was having boost controller issues. havent dyno'd again on my own car at higher boost yet.

 

[Jimmysmk3]

hmm well you may have just talked me into a pt61 and the price is killer ill def. get it from you. i still have the a340 also so maybe the better spool with help with the auto.

 

[uglymk3]

I had a 4202, just get a flange to weld to your intercooler pipes pretty simple. I got rid of mine because I have a cheap ebay manifold and the compressor housing is just too big to clear the manifold and actually run intercooler pipes

 

[gilberjj]

hmm well you may have just talked me into a pt61 and the price is killer ill def. get it from you. i still have the a340 also so maybe the better spool with help with the auto.

here is a 16psi pull with my pt61. as you can see, cams will help it breathe on the top end as it starts choking out a little before 6k. i would get the pt63 if i were you. if i was above 4k, and i hit the gas, it was instant boost. not too much below 3.5k, but its as easy as a downshift. the 63mm will flow more a the top end, and they are identical besides that, so they will spool practically the same.
and i recently got cams, so it should help my engine up top

i see no link.

About the 4082 - IMO the gt40 exhaust is too big (mismatched) for the 4082 compressor . If you only want 500hp , get a 500hp exhaust wheel such as stage 5 or gt35 ex. wheel , otherwise you are just buying lag .

how is it too large? they make a 0.68 a/r turbine for the gt4082. i know, i have one. havent run the turbo yet but i expect the spool to be similar to my 57trim ct26 and still make over 500rwhp on 93 octane fuel as ill have much better flow and some mild porting on the head, standalone, ffi, new i/c, larger exhaust, etc... engine is still being rebuilt so thats why it hasnt been tried out yet. also, mine doesnt have the vband outlet. just a standard slip outlet, but it is antisurge. my friend dave is polishing the compressor housing currently. once it is done ill post pics.

 

[logan]

No , no ..sorry for the confusion . I was talking about the exhaust wheel not the turbine a/r . The gt35's exhaust wheel , for instance , is smaller than the 4082's exhaust wheel , yet the gt35's compressor flows more than the 4082 compressor wheel , so by comparison the 4082 would seem a little mismatched .

Don't get me wrong though the 4082 is probably a nice turbo , it just that the 4082 has a hi flowing exhaust for its rated hp . Maybe it was designed for a diesel .... i don't know .
