Finally I got me exhaust upgraded.
I couldn't believe that because the turbo was already maxed out at 1.35 bar. I was so curious that i hit the dyno today and the car on wastegate pressure gained 10hp(250 at the crank, 240 before) but at full boost the numbers were exactly the same(285 at the crank).
Maybe see if you can get a second map sensor to put in a charge pipe preferably right before the throttle body, and just use it's signal as a gauge to compare vs the actual map sensor, so see how much pressure drop is going on? I'd assume this shouldn't be terribly hard with a standalone?
Cool build, still following
It's from an MX-5 1.8/2.0. I also had to swap the power pins and I had to drill the Fng out of the holes on the body to boltWhich TB did you swap in that fit? I did a search years ago and I got an RX-8 one for cheap, but we had to swap two pins on the connector to get it to work correctly. I tend to remember one of the coolant lines was in the way as well so we made a plate adapter for it to be able to rotate it for clearance, so we could mess around with it. I am curious which one you found that swapped in which is nice.
I was between the MX5 TB and the TB that you are mentioning but I wasn't sure from the photos if it is bigger than the stock(I had send a couple of messages to some sellers in order to measure them but no luck) so I decided to go for the MX5's.I think its a TB from late 1.6 Mazda3, I have the same round about 1 year with no problems in mazda 2 1.3. Gives a litte better acceleration and a bit less restricted breath at high RPMs - I Think. The difference is round about 5mm in diameter only in the inner tube not in the outer diameter.
If you dyno this Im intressting in result. For search of this TB - Ebay will help especially with side by side pics.
