how's it goin guys...

for the past week, ive been compiling tons and tons of info on this forum about these 2 turbos. i had to venture over this way since the SRTForums people are so uni-dimensional and cannot look at things from a wide array of views.

i have a built bottom and top end srt-4 (yea yea, save the flack for another day about the neon ).
8.5:1 pistons. crower s2 cams. full bolt ons. race head. JM Fabrications sheet metal intake, 70mm tb etc. etc.

i originally had a 50t but decided to go bigger. at this point im stuck between the 3065/3082 and the gt35r... both w/ the T3 .82ar. my rev limiter is at 7k. im building another bottom end on the side right now to handle 7500rpms...so lets keep that in mind.

my goals are basically...run 22-24psi on pump/race mix or pump/meth. and get as close to 470-480 on that as possible, and run 28ish psi max and get w/e results the turbos will get me for that on race gas. would like to be in the range of 550-600 (can the 3082 do that?)

seems like there is nothing but love for the 35r aside from the slight spool issue. thankfully you guys can rev out to 7500-8k to make up for that though...

while the 3065 seems to be basically split 50/50....w/ 1/2 saying its a great inbetween turbo (obviously between the 3076 and 35r), and the other 1/2 saying take the slight spool hit for the greater gains up top...


ive seen the dynos' posted of the 3065 v. the gt35r from buschur as well as other various dyno's from other 3065 owners...but its so hard to compare since i am not use to what the "average" typical spool is for a 2.0 and 2.3l stroker owners.


so i guess basically...:
when does the 35r start to surpass the 3065 in overall hp? 25psi? more?
how much of a spool difference is between the two?
for a 7k rev limit, would i be better off w/ the 3065? what about the 35r? 7500?
mind you...i have a fully built top end, so my motor can handle w/e it tries to digest.



ive had a 42lb, 47lb, 62lb, and back down to a 49lb turbo...so ive had alot of experience w/ really good mid-range turbo selections, but none really that are hard hitting, higher output turbos like the 2 mentioned.


any input will be great, since im ordering 1 of the two this monday to replace my now, blown 50trim/.48ar.

thanks guys!

 

Get the hta35r and call it a day, spools faster and better top end. You also have a 2.4L so lag wont be an issue. Hope this helps

 

looked into it...BUTTT i cant afford 1700. thats a lil steep. and i cant afford to be down any longer. my car's been down for 3, going on 4 weeks now, and have been car pooling everywhere while i saved up 1400 to get a new turbo...i know FP is a lil backed up on their orders for it (several weeks from what i read on here).

so basically...stuck between these two, and really not looking to go over the 1200-1400$ threshold for a turbo.

 

how bout you get the 35r now then when money gets straight you send it in for the hta treatment? thats what i would do...but thats just me...

 

35r

 

possible...def. possible.. tho all my funds for the next year are taken up by funding my 2nd block so itll handle 7500rpm's, and to pay off the credit card bills for funding the block/top end i just finished on my car as of right now. lol

for the sake of right now though..given my budget...3082 or 35r?

460-480pump/meth. 550-600race


i noticed dynoflash got what..501awhp out of the 3065, and jarrod@buschur made in the 480 range?

converting a MD dyno to a dynojet (alli use over here)...is about 12% conversion typically...and tack on an additional 10-12% for less drivetrain loss...so does 500Awhp translate to roughly around 620Fwhp if im doing my math right?

guess im just trying to educate myself more on the 3082 moreso than the 35r since the 35r is far more common than the 3082.
only person i know running the 3082 on the srt is a shop car, and its running 10.6@132-135mph..

 

so ill group the HTA peeps into the 35r category...

35r - 3
3082 - 0


whats the spool difference between the two? anyone know by chance?

 

your looking at 200-300 rpm sooner on the 3065 tops. 4700ish for the 3065 and closer to 5k on the 35r (30psi) i dont really think the spool of the 3065 outweighs the power of the 35r. since your on a bigger block i think your gonna need/want the extra flow up top. orrr you could look into the gtk550 turbo like i have, i have seen it do very well in the srt4 crowd. (505 whp at 24-25psi) but its also pricy. (1595)

 

Sounds to me like you are dumping way too much money that you dont have into you car.

 

I get the 35r....i got one and the lag is not that bad and besides you got displacement, so spooling that turbo is gonna be easier for you.

 

From what I've seen and read the 35r is a better choice more power and the lag will be overcomed if you get the HTA in the future plus you have a 2.4. Also if you are only gonna run 28psi of boost max I don't know if you'll need a 8.5K rpm limit like we do since most of the 35r guys here are running like 30psi on pump and 35+ on race gas. For the most part the reason why they use all of the rpm limiter is to avoid over-shifting in the 1/4 mile. Good luck and keep us posted.

 

the 30R is a turd compared to a 35R, there's no comparison...way better pump gas power and with race gas it's even better.

 

35r is better choice hands down.

 

wow. everyone is all for the 35r.

might as well do it, and do it right.

if i got the money down the road ill look into that HTA upgrade.

thanks for the insite guys. :thumbsup:

 

good man
