Everybody on the forum by now knows about my powerlab mellodrama and my continued quest to achieve 500+ whp on a dynodynamic dyno. I came across this interesting upgrade for the GT3582R turbo. It would be an direct swap on the powerlab kit and the cost would be about the same as an water/meth kit. It's the HTA gt3586R. What do you guys think??

I can assure you the turbo is not the problem. I've seen GT35R's put down over 600whp. It won't hurt though.

 

its not worth it. there's just not that much difference. 600$ is $$ for a compressor housing/wheel, when good chance its your turbine side causing problems. Plus the HTA upgrades on the greddy's have never been shown to be any better...

If you are going to upgrade the turbo then get soemthing bigger like this http://store.forcedperformance.net/m..._Code=Turbo-FP

or a PTE 6765.

you could also get your downtube flange modified and put a T4 flange on there and run a 4088

better yet, sell the PL kit and get a used greddy. You'd probably break even in that swap.

 

meth is the key to everything, don't kid yourself.

 

6765 is a nice turbo. On 14psi mine is already well over the 507hp my vortech put down. not only by feel but comparing how fast speed increases in a gear per old logs and doing rolls against previous cars that pulled on me.

This is untuned and wastegate spring, so it'll definitely put down the numbers. You'l lhave to change the downpipe but no matter what you're going to have to change that according to Intense (when upgrading to the 37r)

amazing what a little tq does for ya...

that and my usable range is a lot longer. 14.5psi was at redline for vortech. Now 14psi is at 4500rpm. It'll be nice when i get it tuned so i can safely run it through 8k like before.

also, i forgot to note, the 6765 like rich mentioned and i also recommend is almost identical to the gt4088r from garrett. So no doubt it will outperform the 37r

 

So your goal is to hit 500+ whp on a specific dyno?

Just my thoughts…if you haven’t already done so, I’d take the car down to the local drag strip and see what it traps…I could care less what one dyno says if I’m trapping 120+ mph or so…

And I’d do meth injection before I touched the turbo.

 

was also gonna go this route but would require changing the dp n prolly the intake pipes... also not sure if it'll be a drop fitment cuz my turbo's barely clear the wall... at that point it'll almost be like customizing my entire piping... when i upgrade to get the power i want n leave more room in the future for when i want even MOAR power i'll prolly go with greddy twins...

 

u could avoid some headache thinking about hacking a turbo kit... and go with gt37r upgrade, a comparable size precision turbo.... if you look for more power than that, i don think greddy twins would make much sense, to achieve ~50+ whp on race or ~50-60whp+ on pump gas...that probably is already put you beyond any possibility of achieving any reasonable traction on the street... id look at a twin kit that gives you 800+whp capable kit if looking for more power... the engine you are thinking of building will handle it

 

Don't count James out

 

here's the key, ANY upgrade in turbo requires a piping change. even the "simple" upgrade to the 37r requires an new up pipe.

I think the 6262 is the size of that 37r (or very similar) but the 6262 with a billet wheel will shine more on higher boost.

 

why would you need a pipe change? its the same flange, with turbo in the same spot.

 

curious, to what a 500whp dynodynamic Z is expected to trap at?

 

WE are going to try a couple different things with the gt35r to achieve my goal before I completely give up on the turbo. I have spoke on several occasions with Garrett, IP, and Forced performance about my current situation and think I can make up the 40-50whp that I would like to achieve for a reasonable cost without changing the turbo. I like the gt35r powerband and don't want to make a radical change to gain 50whp.

 

idk, intense posted that it needed to be changed in order to upgrade. It's the first post of that 600 something hp powerlab thread.

 

Probably since the dimensions are different.

^^^Chris, i know there was no bad intention, but that is not correct, lets not confuse people ...there is a link you need to check(and everybody else unsure): Go to this full race site to see the gt37r linkwe are talking about.
-> http://www.full-race.com/catalog/pro...oducts_id=1107 <-

secong information around that IS incorrect is about the upgrate to gt37r piping changes...

i have no clue where he was going in his 1st post here , but on post 13 str8 did got it right...there is NO change from GT35r Kit piping. You loose the intake/filter because of the compressor is 4" inlet....thats all.... mesh is suggested... or bastardizing the rad support a bit and make custom pipe for filter like gt35r version but 4", you can get the similiar sized green filter still...its pretty good quality

 

its not that radical...and nothing that "bumping" a bit rev limiter might be all that is needed to compensate.. if you already have that in your tune, then isnt much "radical" to upgrade a turbo and a gt37r wouldnt requiere a piping change....plus meth WILL give you quite a bit of benefit...and u know with different octane you would surpass your goals of whp.....just suggesting... i know the cost on the gt37r but there is nothing else for piping change costs....i guess a mesh... and u could recoup some selling the gt35r turbo. perhaps someone interested in a kit can save up by not having to get the turbo out of the kit if that can be worked out..... just throwing a few ideas around.

i totally agree

 

I was assuming the info regarding the piping change was correct. My bad.
