My 500rwhp SR Build thread...

[idahotuner]

where are the pics of the turbo set up. i want alot of pics. next to things such as dollar bills, taco bell cups and babies. i did check on the turbo and there is a .63 version but i think that would be way to restrictive on the exhaust side for it to flow the right amount or air to spool the compressor side

[SilviaSpec-R]

nice build so far. show that video when up and running around.

[Solow240sx]

There will be plenty of pics as soon as the turbo kit shows up!!! And i can get everything together!!

Thats sweet

[idahotuner]

waht cams are you going to run with your set up.

[Solow240sx]

I am running Tomie procam 270's..

[idahotuner]

whats there not to love about a gt3582

[datsun2401972]

The fact that I can't fill all those holes at once!

[idahotuner]

haha word

[spanishricer]

whats there not to love about a gt3582

The fact that mine says GARRETT on the turbo.

...eh where's my grinder at

[idahotuner]

i am going have my compressore housing powder coated blue

[Solow240sx]

Haha, im gonna have my intake manifold, valve cover and turbine housing done a candy red, waiting on my turbo to show up though...

[playero_loko]

Feaking A man!!! that thing is massive... even my 3076R looks tiny compared to that one.

[Solow240sx]

Waiting on stuff to show up still, I have some small stuff i've been working on! Im going to the junk yard tomarrow to look for a Q45 throttle body, So i can get the manifold all welded and done before the turbo kit shows up..

[playero_loko]

solow,

were you the one tearing your engine down? or you had help... man, i need/want to do the same to mine, i was told by the kid who had it before us that he had installed cp/egle combo however i'd like to make sure of such b/c i wanna have a rod thru my block chu know! damn anyone in South FLA good with teardowns?! sorry for the thread jack

[pauliedrft]

Nice set up . ill be watching this

[Solow240sx]

Yes i tore mine down, but i had a local speed shop build and balance the bottom end mainly b/c i no them very well and got it done pretty cheap otherwise i would have put the bottom end together..

[idahotuner]

ok i discovered something. full race has 2 gt35s. which did you get. http://www.full-race.com/catal...=1841 or this http://www.full-race.com/catal...=1129 the first would spool quicker then the second. because of the smaller A/R but the other will have more top end. i think i might go with the first one because of the advantages it offers

[spanishricer]

I have the actual Garret GT35R, with the 1.06 a/r, not the Turbonetics version.

It was discussed, and I was told it would be the best fit for my application, since I wanted to make power up to 9000rpm.

[Solow240sx]

I am also running the Garrett GT35R im not a big fan of turbonetics, and i dont think the turbonetics gt35r is dual ball bearing..

[spanishricer]

Yeah, if I was shooting for 600+whp and looking for a journal bearing turbo, I would rather go with a Borg Warner S362 than that Turbonetics turbo. Alot cheaper too.

[idahotuner]

full race doesnt have on advertised witha smaller A/R on the twin scroll turbine. i want the .82 A/R but twin scroll. cause that would work better wit hmy setup. and street ability

They used to have a .78 twin-scroll housing for the 35R last year when I ordered mine, but Geoff didn't like it.

His words:

cool wanted to make sure you got the 1.06 and not the .78! the 1.06 is definitely the one to get

[playero_loko]

solow,

the q45 t.b. was purchased from ebay however it someone selling it not a big time seller, thats how the thing is polished... i didnt pay for other than the price of it, as far as the flange goes my brother replied to you in regards to the flange... i believe he posted the link and all.

as far as the engine goes, there's a few things done but not much more... we'll be taking the car to the shop pretty soon so they can make the i/c piping, mine is going to be 2.5" hotside and 3.0" cold side. tunning and every little thing needed to make it work.

he other thing that i was having problem with was my downpipe... it wasnt linning up with the full-race one, so i have to chop a flange from either downpipe and have it match the other one... so if you have a hks then youve been warned

[spanishricer]

Do you have a pic of the Full Race downpipe?

We're building a custom 3.5" downpipe for my car, and I'm just wondering how the Full Race one curves and twists at. Not much room to work with!

[idahotuner]

1.06 is to big for wahti want .84 or .82 would be perfect. cuse it still give me low end but peak around 8000

Well you have to remember, A/R's on twin scroll and single scroll turbos aren't quite the same.

Twin scroll turbos spool sooner, but the divided housing will eventually choke the peak power off quicker than a single scroll counterpart. That's why you see all the twin scroll turbos available with higher A/R options...because they need the higher A/R's.

A different exhaust housing on most turbos will change spool, response and power. However, GT turbos behave differently from other turbos...

For example, use a GT3582R .63. Lets put it on a stock honda B series GSR engine. It will spool around 4600 rpm, make up to 550 whp at high boost. Change that to a .82, it will spool the same at 4600 rpm, have better response, and make up to 660 whp at high boost... This holds true for virtually every GTxxR series turbo i have tested, as the wheels seem to optimized for flow moreso than pressure.

Some interesting things to note is that it is often better to put a small trim turbine wheel in a bigger A/R housing to solve a spool up time problem rather than a putting an extremely small A/R housing on a large trim turbine. The larger A/R housing can offer more expansion across the turbine allowing more energy recovery by the turbine to help spool the turbo up quicker. A good way to think of this is to try a smaller turbine trim but in the same housing, not to go to extremes. Turbines usually work the most efficiently in housings around the mid range offerings in A/R sizing. Generally the turbine/housing combo was designed around this mid size and the blade angles, etc are optimized for this, another reason to avoid extremes either way in A/R when configuring your turbo.
