CHESTNUTXE 7,312 Posted August 13, 2016 How does one size a turbo ,like is there a common language like most of us no that a common supercharger is a 6/71 size but what about turbo's,i see stuff like garrett 35/40 does that mean that one side has 35 fins and the other 40 ?

351XD_Fairmont 604 Posted August 13, 2016 I always thought it meant size in mm, i.e. 35mm intake 40mm outlet Share this post Link to post Share on other sites

CHESTNUTXE 7,312 Posted August 14, 2016 ok great info but for a 4.0 litre engine how do we size the turbo needed ? Share this post Link to post Share on other sites
FORD_MAN 1,026 Posted August 14, 2016 BA BF XR6 turbos run a GT3582R & FG XR's run a GT3576R but depends on what power your chasing, saw a turbo terri at a dyno day last weekend running a GTX42 making 460AWKW, & my mates turbo territory makes 233AWKW with basic upgrades, 42lb injectors, exhaust, fuel pump, F6 air box, tune.

scottly 475 Posted August 14, 2016 What do you plan on using the car for Street, drag, drift, circuit that play a big part in turbo size required Share this post Link to post Share on other sites
Butcha 111 Posted August 14, 2016 Google and have a read of turbotech 101, 102, 103 if you want the specifics on how to size turbo correctly. Sent from my SM-G928I using Tapatalk Share this post Link to post Share on other sites
CHESTNUTXE 7,312 Posted August 14, 2016 around 300kw street driven car,similar or close to factory spec's ,starting with a non turbo engine and retro fitting it. Share this post Link to post Share on other sites
scottly 475 Posted August 14, 2016 If I were you I would try and get my hands on a ba-bf turbo or a fg turbo they can be picked up pretty cheap and the come on fast and more than capable of 300 rwkw Share this post Link to post Share on other sites
CHESTNUTXE 7,312 Posted August 14, 2016 do you mean just the turbo or the whole engine ? i still havent decided to keep my ED 4.0L or the barra engine,has anyone seen that turbo exhaust adaptor on e bay thats selling,it fits up to your std exhaust manifold some how.

FORD_MAN 1,026 Posted August 14, 2016 Yeah " Spoolinboost " in Adelaide make the cast J pipe look them up on facebook they have a FG with 570k km E gas engine with valve springs & there parts, did 11.7/121mph at aff drag nats on 10psi 1 Valvebouncer reacted to this Share this post Link to post Share on other sites
CHESTNUTXE 7,312 Posted August 14, 2016 sure beats payin $1200 for a 6boost manifold Share this post Link to post Share on other sites
CHESTNUTXE 7,312 Posted August 14, 2016 Hey that spooling boost package is just what i am looking for,$2000 bucks gets everything ,turbo intercooler,ect ect,thankyou. Share this post Link to post Share on other sites
XPT 673 Posted August 14, 2016 Gt3582r is How does one size a turbo ,like is there a common language like most of us no that a common supercharger is a 6/71 size but what about turbo's,i see stuff like garrett 35/40 does that mean that one side has 35 fins and the other 40 ? A gt3582r has a gt35 turbine wheel which has no reference to actual size as far as I know, just a model name but the 82 refers to the exducer ( largest diameter) of the compressor wheel which is 82mm ( inducer around 61mm), the Garrett gt3576 on the FG xr6t has the same turbine wheel with a smaller exducer of 76mm. The Garrett GT4202 uses a GT42 turbine wheel with a compressor wheel exducer of 102mm, so you can kind of understand the frame sizes that Garrett uses. As far as turbo sizing goes, why not copy Ford ? : A GT3582R with a 1.06 ar turbine housing, capable d delivering 400rwkw with minimal lag on a 4L. Generally turbo manufacturers supply turbos with well matched turbine and compressor wheel with a recommended engine size range to work with. Volumetric and other efficiencies come into play when selecting a turbo. But generally, go for a turbo with a compressor map within the desired pressure ratio.

CHESTNUTXE 7,312 Posted August 14, 2016 i read somewhere that the ba-bf garrett was quite big for its application,and the new one for the fg spools up quicker and is a smaller turbo Share this post Link to post Share on other sites
Valvebouncer 2,389 Posted August 14, 2016 Yeah " Spoolinboost " in Adelaide make the cast J pipe look them up on facebookthey have a FG with 570k km E gas engine with valve springs & there parts, did 11.7/121mph at aff drag nats on 10psi That's an awesome looking kit! I wonder if it will fit in an xg? Judging by how the turbo sits I'm thinking it might foul on the shock tower. Sent from my iPhone using Tapatalk Share this post Link to post Share on other sites
XPT 673 Posted August 14, 2016 i read somewhere that the ba-bf garrett was quite big for its application,and the new one for the fg spools up quicker and is a smaller turboThe FG still uses a GT35 frame turbo, they just have a slightly smaller compressor wheel. BA-F use GT3582R, FG use GT3576R. The smaller compressor wheel probably partly explains why the FG Turbo models have better low down torque. Share this post Link to post Share on other sites
CHESTNUTXE 7,312 Posted August 14, 2016 The kit say's fit's xh ute im sure with a bit of soughting it would fit a xg Share this post Link to post Share on other sites
Ants 6,370 Posted August 15, 2016 Can't go wrong with a stock ba/bf turbo on a 4l. The fg f6 retained the bigger turbo, only the xr and g6et had the smaller one. 300rwkw is just scratching the surface power wise of a boosted 4l (single cam or barra the principal is the same), there is really no need to look any further than the stock bseries turbo at that level. 1 Valvebouncer reacted to this Share this post Link to post Share on other sites
CHESTNUTXE 7,312 Posted August 15, 2016 ok good info,my xg engine is 8.8.1 compression at only mild boost and 300kw levels will i still have to drop the comp a bit ? or just leave it. Share this post Link to post Share on other sites
XPT 673 Posted August 15, 2016 Just leave it, that is pretty much perfect for boost. As long as you're running an intercooler, using decent fuel and it's tuned correctly Share this post Link to post Share on other sites
