Just bought another set of Supra TT chrome wheels. Just gotta wait for the seller to ship them out. Then I will ship 2 of the rears out to get widened. Then take the 4 rear wheels and get them rechromed. Then run 2 rears in the front, and the widened rears in the back with a 315/40/17 tire. Oh man.

Changed the spark plugs yesterday, got the same ones I've been using already.


NGK BKR7E gapped @ .024


And recently found out that you can use the SC400 Toyota oil filter on 2JZ motors. The SC400 filter is about half an inch larger than the stock 2JZ one. It's a common thing on Supra's, so I will install it tomorrow along with an oil change using Rotella T6 5w40. 


Changing the spark plugs made a big difference in spool this time around (as well as the slight adjustment in tune), maybe mine were worn but they didn't look it. I change oil and plugs very often. My oil is changed every 600-1000 miles. Spark plugs about every 2-3 months.


Boost is hitting much harder now, and a lot of it. As soon as 4000 rpm hits, it's crazy drama. Wheel spin, wastegate scream.. Hit 34.3 PSI today in 4th gear, and it scared me a little. 


Dyno Day is coming up March 1st, and I will be in it. Gotta do a couple more pulls and mess with the tune. Aiming for 35 psi 850whp.


Also, the Supra wheels I just got are up for sale.


I don't need them.
