Long rod 2.0 vs standard 2.0

Im in the middle of a build with my evo 8r at the moment I am looking at long Rod setup and wondering if I can have some people's input on there I'm looking to make 800+ power is the longer rod definitely going to be more reliable way? Thanks guys

if youre looking to make that much power the long rod is going to be a better choice since youll have option to really rev the car with the LR.

making that much power reliable goes out the window.

Reaving the car is fun, when you can pull longer in the gears , 9500 PRM

chouse a crank , that have small nocks and match it whit the right rods , and you will make som good power ,

the other thing is a strocker enginge , but then you wont be able to rev that mutch ,
but then you will make power more easy whit a big turbo , precition 6262

Think that 800 hp is not cheap , you will need a lot of maintenss , a big fule system , intake , mainfold , indjectors pumps , enginge management , tune , IC , e.c.t

I dont wanna broke your dreams but 500 + is more driveable on the streets , and you will have more fun , and less headeck , and more use of your car

standard 2.0 will rev higher than you will ever need. soooo standard 2.0 if you have a good 63 block.

Edit...on evo 8 4th... or 4.11 and taller gear.

Standard rod is capable of 11,000k...repeatedly. If that is really a consideration, as in you have a turbo that makes power at 9800 (42R) and want to have a full powerband then maybe. There is always a a place for everything. For smaller turbos that might peak at 8k and only be revved to 9300-9400 it is not really a consideration. In some cases based on the head port, it might actually start to hurt performance. It is most likely rare but I experienced it personally so I know it can happen.

Well the turbo I'm putting on the car is either hta3586 or most deff 6766 my question is what build should I do 2.0 or longrod what is most common build... I'm looking for 9 sec consistant car thanks guys If I need that lil more rpm for the trap I wanna make sure I can aleast rev a 2.0 to 10k with supporting mods I am running stock crank

3586 on a 2.0L makes peak power around 8300 with the right combo. A 6766 I would presume should shift that to the right some more.

For a 156mm long rod setup in a 4g63 the advantages over a regular 2.0L are:

Better rod ratio of 1.77 compared to a 2.0L 150mm's rod ratio of 1.7
Better rod angle so less loading (less friction too) on the bores and bearings.
Longer dwell time at TDC = increased VE.

In practice long rod motors are a safer way of shifting the power band higher up the rev range. This advantage becomes more apparent with the larger turbo set-ups.

Leave the LR's for the 2.4L motors. There is no point in a 2.0L. Std built 2.0 revs to 11,000 but oil pump speed, oil starvation etc are bigger considerations than anything at that point

Emery@STM loves the Buschur 2.0LR. There's one locally on an FP Red, and a couple 6262's as well. I am pretty sure his new RS will be running a LR as well. All with great results and making 570+ Mustang Dyno whp.

No, the stroker piston has too much dish for the 2.0L displacement. The piston is set up around being a 9: 1 with 2.3L to squish, a 2.0L with 2.3 pistons ends up at 7.8:1 or something.
