anyone have any dyno sheets or numbers for the apexi turbo and the gt35/40. just looking to see how much of a difference the spool rates are. i hear that the rx6 spools damn fast, but how fast is damn fast. also hear that the 35/40 isnt much slower than stock. just trying to get some insight on where my money should be going. i know that the rx6 has yet to see anything over the 420hp mark but the 35/40 has seen almost 500hp. these kind of questions seem to not be allowed on the other forum. thanks

Usually the rx6 doesn't make more than 360rwhp, that kit really isn't much of an upgrade from the stock twins powerwise, but it does clean up/ and make things more reliable. What are you looking for? I'm assuming a streetcar, as these turbos are definatly not drag units. I would say you would be way better off with the gt 35/40.

 

the rx6 feels like its a hair slower than stock, it has 10-12psi by 2500rpms

The boost curve on a 35/40 seems to go as follows you will see positive boost by 2200rpm, 7psi by 2500, 10 psi by 2700, 15psi by 3300,this of coarse may very alittle depending on other things. I've got alot of experience with both and I wouldn't even consider the rx-6 anymore, it's great turbo kit don't get me wrong, but you have alot more room to grow with 35/40 and it can be rebuilt locally.



Thanks,Sean

 

Offtopic sorry, Hey Sean, how much do you guys charge for boost verification and a compression check for an FD. I'm buying a 3rd. Gen in a little while so I'd like to know. Thanks

Go with the 35/40, its gona spool up just as quick as the rx6 but have a ton more potential for power. The gt35/40 is really the hottest turbo right now, great for the street and good for the strip. The max you are really gona get out of the rx6 is around 400rwhp anyways, most the time you see around 370ish plus or minus.

 

whoa, havent been here for a long time. thanks for the input. what im looking for is something that is streetable yet gives me fast spool. im a heavy autoXer and love road races. i do maybe 2 drag races a year just to see how my mods are adding up. i need the low end. i like the stock twins, but everytime something goes wrong i have to take off a thousand hoses to fix the problem. if i was going to spend over 2K on the BNR's(which i dont think i will), i might as well save up a tad more for something that is completely new and not rebuilt. im not docking the BNR's just from what i have heard about the 35/40 is bad ***. give me everything there is to know about the 35/40 people.

thanks

Silverninetythreee made 435rwhp @15psi and 470rwhp @20psi on the gt35/40. As a-spec-tuning said, you will typically see 15psi by 3300rpms, which isn't that far off stock and obviously much quicker spooling than say a t-78.

 

If you're going to do it, you could do it better than right. Spend the (unexpected) money on a Pineapple Nocab-ported engine, a GT35/40, and come hither and let me tune you for 550RWHP at under 21psi.



I've tuned a couple of Rx6s, and they in no way compare to a GT35/40. Even stock block cars. Put that baby on a Pineapple engine and you go, now!
