Gt 35r

my friend is selling his gt 35r off his sti. i was interested in buying it off him i have 05 5EAT with a fmic,downpipe, exhausat, bov,intake, up pipe. i know i would have to get new injectors fuel pump . i am going to have a custom external wastegate with headers . Anybody have a 35r turbo in there legacys ?

Your also going to need the climberD@hexmods valve body. Check out his thread in the tranny forum.

i just put a 3076 rotated turbo on my 05 and love it but mine is also a 5 speed! its making 360whp on a very conservative tune!

Holding a 35r on a 5eat will require extensive trans mods.

 

You will also need a built motor.

A member on here has a gt40r on a 5eat with ipt built trans and F1 valve body.

what kind of trans mods ? i am looking to get around 450 to the crank i know if i go over that i need to build my motor

If you only want 450chp, the gt35r is the wrong turbo. You could get around that with a 20g, and easily surpass your goals with a gt30r.

 

450chp on a 5eat is somewhere around 320-340whp. All you would need for that power level is fresh fluid, proper maintenance, and the F1 valve body by ClimberD.

my friend is selling it cheap to me

If you detune the 35r enough so that it doesn't grenade your stock internals, it will not be fun to drive at all.

Buy and then sell it for a profit and buy a smaller turbo that will give you what you want.

Why did you get a 3076 if you only wanted to make 360whp?

 

A TD06-SL2-18G could have gotten REALLY close to that power number, and had a LOT more down-low.

I've never seen a TD06 18G make 360whp on a LGT. Its pretty rare for 20Gs to even hit that mark without meth/water or E85.

That's because no one really runs SL2 18g's (partially because they don't really exist anymore). Everyone drinks the 20g kool-aid because, hey, bigger is better right?

 

And if that 360 number is SOOOOO important, an FP Green will easily clear that mark on pump.

my buddy with an 09 rex is pulling 381whp on my old amr cxr500 20g/td06 with meth. stock internals and 5mt for 2+ years. lol.

What is the FP Green core? Is it a 20g?

 

381whp on my old amr cxr500 20g/td06 with meth.

exactly lol

 

But yea, I'm just saying don't count on 360whp... it may be possible, but only with a full listing of supporing mods. 350whp is more reasonable, and 330-340whp is the only real consistent numbers I've seen on pump.

The Green is a 30R based turbo, and the Green HTA flows 56 lb/min. 20g's flow much less, typically around 46-48 lb/min.

 

There is almost no functional difference on the street between 340 and 360whp. The 18g will simply be a better overall turbo than the 20g. That is plain right off the bat when you look at compressor maps.

 

Pressure ratios suitable for pump gas on a 20g in a 2.5L push the turbo off of its peak efficiency island. The SL2 18g, however, sits deadpan in the middle of its highest efficiency zone. Stock engine Subarus cant push a 20g hard enough to take advantage of them. When you do the mods it takes I be able to handle a high-boost 20g, you'd be better off with a Green or 30R that'll make more power at less boost with better spool.

 

You are grossly under utilizing a 3076 if you are only making 360whp. A Green would behave much better, and make the same or more power (a friend made 481whp on E85 on his green in his STI. Then upped to a GTX3076 and made 580whp on E85).

 

No one, at all, needs a 35R. Not unless breaking 600whp is your goal.

By high boost 20g what do you mean? ~24psi, or more?

You'd have to look at the compressor maps. I havent in a while, but I do recall it being well above 20psi.

i am thinking of getting a 30 r

dooo eeet

 

You will need climberD to help your transmission before-hand, though.

If you don't want that 35r I'll buy it!!

35r on a 5eat will require more than a valve body mod. You will need more layers in your clutch packs. Even then, it will wear out faster than at stock power levels. Well, maybe. It's hard to get any power out of a 35r on the street, keeping wear down. Depends how you will drive it. Those two things (modified VB and upgraded clutch packs) will take care of your transmission needs. I am far more concerned for the engine.

how much would the transmission parts cost ? i woudnt be maxing out the turboon the stock block

Then stick with something in the 16-20g range.

$2000 or so, largely labor.
