Not sure you would have to call the manufacturer of the pistons and tell them. I went with 162mm so everything was custom. Manley does make a piston for that rod though. I'd have to look it up but I do have a part #

 

You can use the drop downs on this site to look at different combinations/manufactures . The 156mm Carrillo part number is SCR7000-4 . CP piston part number sc7245 for 9:1. Don't forget about a pin upgrade.

FWIW, a 94mm /150mm rod 4g63 has a max recommended piston speed of 9000ish. A 94/153mm is 9400ish. Longer rod then 153mm in this engine can lead to a less then ideal compression height. But , there are a number of people running the 94/156mm setup with decent results so sometimes you have to ignore the math. Look at the honda guys running K24's to 11k.

 

For the 162mm rods Manley part# is 619020CE-4

 

I use 150mm Carrillo Pro H rods with Car bolt, CP pistons with upgraded wrist pin, on stock crank. This is all over kill for my 420hp but if I was going to spend all the time and trouble pulling the motor myself, the money i saved would go into the best parts, if I had it again I would have done the eagle 94mm crank, however I didnt want too much power as I'm trying to keep my 6 speed in tact on the track and hard street use.

 

The plan is to install precision 6870 turbo and try to make over 900whp. It is going to be street car only, my weekend fun car. Some street racing and occasional 1/4 mile runs. My current setup makes over 700whp and it is fun car and I love it but I am always hungry for power. Even if everything is working perfect and car is making nice power I am always looking for something to squeeze couple extra hp. My current motor has some mileage already and sooner or later I will need to refresh it, and I have extra block and cylinder head etc to make another spare motor and can't decide what setup should I build. my current setup working good. It is eagle 88mm crank maley I beam rods standard length and wiseco pistons, but If I can build something that can work better why not to try it.

 

I would go as high as you reasonably can with the available fuel. Off boost power with high compression is a nice bonus to have

 

You are 100% correct here but on other end some people say that high compression on boost will make less power than low compression on boost. I mean on high boost 40+psi. I still did not decided what to do.

 

I disagree with both of you. my 12.5:1 motor on a black didn't make more then what I had in my signature at 31 lbs if I remember correctly. Tuner just didn't have any more room to make power and that was on e85. Car boosted decently but it just ran out of power on the dyno no matter what he did.

 

So maybe I should go with 9.0:1 compression and call it a day.

 

What I just put in my 2.2

 

Lower compression means you can cram more air and fuel in there. If looking for 700whp+ on a 2ish liter engine, then the extra lag from 9:1 probably won't be noticed anyway.

 

Kaj is right. If you are shooting for a super high hp drag style setup, the extra lag and less off boost power won't matter at all.
In my setup, I went with a set of 10.5:1 pistons for street driving on E85. The off boost power is noticeably different than the stock setup and it also helped spool my red just like the green did on the stock bottom end.

At the end of the day, its all about what your plans are with the car and being realistic about what you are going to do. After having a high compression setup, I think I would like a lower compression setup a lot less for my specific use case with is 99.9% street driving.

 

It is going to be 99% street car and only from time to time 1/4 mile car. My current setup is 10.5 compression with 6466 turbo making nice power and I am building spare engine which will have 6466 turbo or bigger 6870 turbo but again it will be street e85 fuel car. Thats why I am not sure what to do because I have high compression now and I dont want to be disappointed when I put lower compression engine. It is the hardest decision I have made for a long time.

 

I couldn't advise in this case. I've driven street cars with big turbos and couldn't stand it (I cut my teeth on big turbo 1/4mi cars). 99.9% of the people I know of that went that route sold their cars because they were "no fun" and got bored.
I'll let the others chime in as I am on the other side of the spectrum so am like lol l'm always curious to see other builds pan out, though.

 

yea you are right, I know a lot of people that went with big turbos 6870 or bigger and than they sold their evos because they were no fun. A lot people saying 6266-6466 is the best range on the street. 700-750whp its where I am now but I am always hungry for power haha.
