  1. Is CSS worth it? L15B7

    You will be sure to get a lot of conflicting info, and honestly at the end of the day do what your engine builder (If they are good) recommends. CSS is a great product and works very well in these applications. Is it absolutely needed at 500hp? Nope, we ran ours above that for a good amount of...
  2. MAPerformance - Civic X 1.5t Performance Engine Build Thread

    I dont want to shoot myself in the foot here, so let me respond carefully lol. We are working VERY hard on it, we are in the final stretch, but part of the final stretch is validating every little thing. That takes time, and that takes the willingness to change things we may have already been...
  3. MAPerformance - Civic X 1.5t Performance Engine Build Thread

    Honestly, there are so many variables there its a hard question to answer. Base answer, no, they wont make less power because of the block. But, there are things that will be different. Alternator mounting is different, No oil squirters on the EX block, and a few others we have found so far...
  4. MAPerformance - Civic X 1.5t Performance Engine Build Thread

    The base model and the Si do have a few differences we have found so far, Block castings are different, rods are different (Only in material it seems), pistons are different (Compression ratio), intake cams are different, and honestly im sure there are more as we keep going with these things.
  5. MAPerformance - 500+WHP Civic Si on Stock Bottom End! Excited to Share!

    Absolutely, the whole design of the kit is to make it compatible from the GT2860 all the way up to the GTX3071 and anything in between giving customers lots of options on the turbo side. We will also be looking into options for the different covers as that is only a piping change in our kit.
  6. MAPerformance - 500+WHP Civic Si on Stock Bottom End! Excited to Share!

    Rear rate is the same as their factory rate (Due to the spring they are utilizing, current set up is 10k Front, 8k rear. Most recent weight on the car was 2880 with half tank and 200lb driver. Most of the work was done on the valving side from our requests, just to make them a bit more...
  7. 10th gen platform- have we ran off all the pioneers of modding?

    We have been lacking a bit on updates, but not for a lack of effort in the shop. Hopefully we have some media coming out soon, but we have made a lot of changes to the car and have had a decent amount of testing going on that will hopefully result in a car that makes some power, and some cool...
  8. Do I need to upgrade Connecting Rods?

    Interesting, both my local dealer and a few online parts houses listed the same rod. That's the only one we have not bought both of, guess I need to buy that other part number and see whats different. Thank you for the heads up!
  9. Do I need to upgrade Connecting Rods?

    So just to clear up a few things in the thread to make sure correct info is out there! All the L15B7 (SI and Non) share the same rod (Part # 13210-5PA-A00) -These are a very thin, light rod, with small M6 rod bolts. The bearings are actually very nice, and in standard Honda fashion work very...
  10. ***MAPerformance Civic SI 1.5t Catback Release and Group Buy!***

    I will not say mistakes do not happen, as we are only human. But we have added many steps to our process over the years, and even more recently from Quality control, to scanner systems for shipping and packaging to prevent issues as best we can. Our shipping team goes though multiple check...
  11. ***MAPerformance Civic SI 1.5t Catback Release and Group Buy!***

    By no means am I saying that there is a huge change in how it sits on the car, and the jig has not been changed in how the pipe is made. Only removing any area for "interpretation" to prevent issues. There are some areas on the car where it just hangs a bit low, when fitting 3" pipe under the...
  12. ***MAPerformance Civic SI 1.5t Catback Release and Group Buy!***

    From all of my records all GB orders had shipped out at least two months ago actually, if not longer. There were a few Black tip ones that were getting re-done from the early batch, but the not black ones had all been shipped long before that. We have made some changes to Jigs to insure they...
  13. 1.5T Flywheel CEL?

    Not at all! The twin is actually my favorite clutch so far.
  14. 1.5T Flywheel CEL?

    ^^ What they said. There seems to be a rumor out there that a lightweight flywheel will cause it on the 10th gen, but have never seen it happen with any of our, or our customers cars.
  15. ***MAPerformance Civic SI 1.5t Catback Release and Group Buy!***

    I know we spent a lot of time playing with location, as in some cases if we tucked it up higher it would hit the body on larger bumps. But, I will take what you are saying back to my team and see if there are any changes we can make! Thank you for the feedback! -Daelen
  16. ***MAPerformance Civic SI 1.5t Catback Release and Group Buy!***

    We have noticed that a few people have had them installed with the midpipes rotated slightly, causing it to sit lower than it was designed to. Is it possible that this is happening on yours? We are also looking in to marking the catbacks on the flanges to prevent this from happening on install...
  17. ***MAPerformance Civic SI 1.5t Catback Release and Group Buy!***

    Just saw your PM, there should be a plug that is included in the hardware kit. If you do not have that, ill get one sent out asap! Thanks -Daelen
  18. ***MAPerformance Civic SI 1.5t Catback Release and Group Buy!***

    I wish I could give you a 100% answer, we are working on finding some local cars to get in the shop to test fit all these parts to validate!
  19. ***MAPerformance Civic SI 1.5t Catback Release and Group Buy!***

    A few things id like to follow up on this to make sure I address all your points here! Damaged Black tips: Absolutely not acceptable on our part, and I was under the assumption I had spoke to every person that had a pre-revision set to get that exchanged, so I do apologize about that, as we...

    He actually ordered a shirt, no special treatment on that order at all. Actually until that popped up was not aware he was a Youtuber.
