What noise did it make before it stopped making noises?

Never made any noises

[Georgiyk]

Soooo... what sort of noises does it make abut 5500 rpm?

this is fun.

BRO

Redline is 6500+ and it needs to hit AT LEAST 6000 to really take advantage of this setup

I have the 885 head and it doesn’t fit because the eta and b25 have different pistons

it fits fine, the pistons arent matched to the chamber correctly but it installs fine but its just not ideal compared to a proper 2.7

[Georgiyk]

you can replace springs or put a head with the springs already installed.

the 200 eta is not much chop for anything, for a performance engine people do a 731 head from a m20b23 or m20b20 which has the same combustion chamber so it matches up with the pistons proerly but slighty larger ports. or they just use the 885 head from m20b25 which while not ideal still is an improvment

Bro shut up no one cares about your 1/4 mile runs

RUDE.

Thats the best way to know if you've made your car better or worse... Id also suggest doing a dyno run, but a 1/4 mile run is more fun.

[digger]

So is there another head that’s identical to the 200 head that can be swapped out or how does it work do you just replace springs or what.

[Georgiyk]

You would run an amazing 1/4 time. Please have a friend record a horizontal video.

Ha, no, this didn't happen under load with just throttle input.

What do you mean

[Georgiyk]

yeah there are bunch of things that need to be added / swapped to get it to work not directly plug and play



high risk of loss of valve control resulting in loft and then valve bounce occurring which has been shown to cause the piston to tag the valves and bend valves because the relationship between valve lift and piston position goes out the window. People usually run the dual springs or at very least the single outer springs (beefier ones from M20B23) even better is the beefy outer springs and the inners which is even more rpm capable than the b25 setup

My ecu is tuned and it goes to 6500 rpm maybe a little more
