Big Turbo Options -- Comprehensive List

[anotero]

I'm entertaining the idea of a big turbo. Who knows if it will last... But since I don't think we have a dedicated thread for the different bt's out there, with their pros and cons, I say it would be a good idea to make one. Y'all chime in and I'll organize the list in the OP.

Hate to burst your bubble but it has already been done. I think the title of the thread is Aftermarket Turbos or something like that.

HOW COULD YOU DO THIS TO ME??

Tomioka IHX475

Pro: Lag isn’t too awful.

Con: Doesn’t make a whole ton more power than an IS38. Vortex costs the same and makes more power without adding any lag.

In summary: Vortex.

Sorry bro, but I'll still play...

DBV2 V2 Journal Bearing

Pro: Top end big power till redline.
Con: It has some lag. The TBB versions spool quicker.

Can you quantify "some lag"? Say, in comparison to IS20 and IS38.

Well, before the "extension" it would be spooled up at around 4300 - 4500 rpms. Now, it's spooled up at 3500.

I'm in the same boat. Vortex seems like the way to go for reasonable goals and most of us mere mortals. Then it's just std vs XL. I'm thinking std and keep it within stock map sensor limits. we'll see lol.

 

[Diggs24]

No point in XL unless you go big fueling too. Then you are playing with the bigboys who like to see how quickly they can get to an engine rebuild.

Full spool? Like what’s psi at 3500?

My hybrid 38(loba L0462) will hit 24psi at 3600 but wont hit the full target of 28/29psi till 4500 but holds till redline... its at 27psi by 3800 though.

I've seen enough BT datalogs to know I will def be getting LPFP +MPI regardless of whatever turbo I go to lol. Worth spending an extra 1k to have lots of fueling headroom and not strain the DI injection window at high rpm etc. Valve cleaning is nice too. With stock ECU MPI control it's a no brainer to me.

Isn't a LPFP and MPI a lot more than 1K? Closer to 2K and that's without a LPFP controller or tune.

 

[jimlloyd40]

I think that you should add TPC and Littco to the list.

I was assuming I'd get a LPFP either way. So LPFP + HPFP vs LPFP + MPI
