Yesterday i installed a 10.5 hotside and a megan manifold on an 04 Evo.. Car pulls so hard to redline its crazy!! The turbo spool on this car is amazing. I drove it b4 the installs and after and the difference is huge!!!!!!!! Who ever says theres no gains from a 10.5 hotside, is bs. Its worth it, pulls harder than my car but this car has 272 cams.The only problem i noticed was that the boost dropped too quickly, theres a bolt missing from the top of the mani that was lost so im assuming its leaking from there bc the gakset is lifted in the corner. Just wanted to post some info for you guys.

 

nice....

no flash?

 

Not yet, the guy wanted to have everthing installed and will be going to the dyno hopefully next week. The boost leak needs to be fixed first

 

The car feels crazy fast!!!!!! specially in 4th gear since it holds boost a bit longer than 1 thru 3rd gear, I can't imagine this car holding boost and a fine tune ....Hey Miguel I'm going to install the final bolt missing to see if fixes boost problem...

Thanks for the install I owe you!!!!

 

You may want to be careful running untuned with cams and everything :\

 

No prb!! Anytime Dont forget also to get that nut and washer for the manifold for the back

 

I totally agree. Good job Miguel for doing the install work.

 

Always nice when you have a friend to help.. I wish there were more EVO owners in my area.. I really enjoy working on them.
