Jeffs MSP GTR Build

[vtec-this]

everything ending up great. I tuned the car last night at 5psi boost on 87 octane for now. It is pulling great. (it was also -6 last night so im sure that helps with the fmic getting chilled thoroughly)

one thing i have noticed is that spool is nowhere near as nice as with the t25r on a 2.0l FSDE. One thing I loved with the FSDET is that when you are cruising in say 4th or 5th and give just a little throttle the turbo would spool so quickly it was almost like n/a power delivery. With the 1.8 on the non BB turbo you have to put your foot down a little bit more than I was expecting. Its not HUGE lag, but it is lag compared to the stock MSP FSDET setup.

Now I know why the GTX came with the vj-20. For DD it is more responsive than the T25.

Either way I am very happy with how the car pulls at 5psi. Now I need those 550s and will tune for 14psi on 94 octane.

once i get a set of 550 injectors i will go to the dyno.

thanks for all the comments!

spool time is directly reflected in your timing..... get a tune for nothing less than 93 octane. im honestly a bit insulted hearing your tuned for "87"
correctly put it should read "de-tuned"

ya im not getting too excited with the stock egt injectors in place. i just need those 550s with 94 octane and things will get interesting pretty quickly.

glad she's running man!! what was your a/f ratio in boost? Sounds like those BP injectors were almost maxed out lol

Itb flange looks great. Want to see vids of this beast running as well.

My BP05 vs the VVT setup. For the VVT I am going to try and keep the injectors in the ITBs. For BP05 setup with the injectors in the stock location I had to have the different flange to clear the stock injectors.




Can you tell I had someone else weld it? lol Jeff < Nice Welding




Meeting the GSXR ITB.







Very happy with how it turned out.
