TTE525R Turbo upgrade. Who is getting this 540+ BHP turbo

What kind of gains are we talking about gn4 do you know? IS20-IS38 type gains? I only ask because the IS38 upgrade is only $1200 (hardware) and for those of us going the JB4 route, that still is the best deal for 350whp it looks like (pricing wise).

Ya which turbo is that gn4r? I just saw the TTE470 and 525 but both require an IS38 core. That being said, the 470 is $1000 cheaper at like $2800 and I think I saw a dyno of ~450whp.

MRC Tuning I think has graphs for a few different ones.

For stock motor and clutches the TTE470 is a better option.

Ya I figured that's right on the edge of stock components needing to be upgraded. Injectors can handle it ok, or we need to think fueling too? I thought it might be right on that edge..

Ok thanks George. I am thinking then that the JB4 is best mated with a 470 then? I.E. that would be the best option for a turbo+DP modded car? (stock fuelling)

With the JB4 we need to see if we can cover the AFR range required otherwise it may need to be coupled with a backend flash. At the moment its a good option but if you planning on upgrading I would wait as there are many turbo options coming out on the short term.

Yeah no, one step at a time.
I won't be doing a turbo upgrade until warranty is out. My only goal at this time is 12.9 with a JB1 :-D
