GTX3576 GEN2 vs GTX3076 GEN2 - What are the differences when installed?
 

Hello Honda Lovers
any Honda owner have try both turbo on his car (only Gen 2 )?
just by removing one turbo and put the other one ?

Also if is possible Dyno graf ? It will be perfect


Garret site give the same amount of power
Also rumors tell that both turbos spool at same rpm

I won't to build a Honda and I cant choose Wich turbo to use

Please only for those that have use both turbo on same car I need to check deferences and spool on this turbos

Very differing power between the two. Compressor map only shows the same capability versus the turnips use the range compressor wheel. The difference is the turbine wheel size,

But you need to determine what "spool" is. The same moment of inertia, or the same savvy of a particular pressure range within a certain rpm band

I never managed to find someone that used both turbos and has a side by side dyno comparisson.
With the same 0.82 turbine housing GT35 will spool slower and make more power. On an 2.0L engine the difference will be small in spool.On a 3.0L engine almost nothing.
If you have at least 1800cc engine and 9000 rpm 0.82 GTX3576 is a better combo
With the 1.05 housing on the GT30 and 0.82 on the GT35 it will be much closer on power and spool.
If you are thinking about 0.82 on the GTX3076 you will not manage to hit 650 hp unless you use racing fuel, or a happy man's dyno :)

On AdamLZ's RB25 Skyline they managed 590whp with a GTX3071 (IIRC) but I personally think that's at its very peak or a "happy dyno". The Shodan has shared many times than the GT30 turbine wheel peaks at around ~560whp realistically.

I personally define the GTX3076 vs GTX3576 conundrum as follows : GTX3076 0.82 for up to 550whp (realistically) and earlier onset of positive pressure. GTX3576 0.63 if you want 600whp and will trade some initial boost response in favour thereof. Disclaimer: I've never used these two turbos but results on multiple platforms and physics lead me in that direction.
