i have a b18c engine .with a stock bottom block and iam also getting my head decked
i want to do a high compression all motor what kind of valves should i get /retainers/ springs?
im also getting my head ported with a 3 angle valve job and also i will be running blox stage 2 cams also what kind of manifold should i run because i currently have a blox 68mm on my car.
what would you guys recommend

 

Wouldn't recommend it on 91. If you can get E85 should be okay.

 

what do you consider high compression?

 

well i dont have access to e85 cuz i live to far from it

 

i just want to run a decent high compression engine and i want to run close to high 13s maybe low 13s

 

stick to around 11:1. lots of engines run that stock and do fine on 91oct. you still need a spot on tune regardless.

 

If your using stock pistons I wouldn't consider that high compression

 

well what kind of set up should i do then because i wanted to go with supertech valves that are flat face

 

I think the flat valves give you like .2 bump in compression it's really not much you can run those with supertech valve train and a eldelbrock manifold an a good header but unless you up the pistons your really not gunna be high in comp. what car is this gunna be in? An R? You will need a serious bump in comp to go 13's and with a compression over 12.5 I think you need to run e85 or race gas bc of detonation of lower grade fuel. And I don't know bout Cali but a gallon of race gas is stupid expensive here in ct do not to ideal for a daily driver

 

so if i went ctr pistons then it would help but what do you think i will be running wit itr because i need this car for work

 

What car would this be in? If you did ctr pistons it would def help. In a eg hatch with good tires and a good launch I'm sure you could break into 13's with a good tune

 

I ran a high 13 in a full weight CRX with AC that weighs 2350 with driver @3000ft with an LS tranny and a bone stock B18CR.

 

13's no problem in an EG with a healthy ITR motor. You don't need to run high compression for that at all. Now low 13's are a different goal. But again on 91 octane don't push your luck.

 

A decently built motor (cams, TB, mild CR, IM, headers) in a "light weight" car can run high 13's depending on driver. Low 13's require a more aggressive build with higher compression, big cams, headwork, big tube header, Big IM, weight reduction, traction & driving


I ran 12:8:1 CR on 93 octane with a full tune. No race gas added. I didn't daily drive the car but, could have. As for 91 octane + high CR + daily driving =
Believe it or not there are people that daily drive on race gas mixed with 93 octane. I know 2.
ekcoupeh22 is one of them. lol

You couldn't have said it any better

 

Dont buy any thing Blox, Skunk 2, Megan, Black works, or any of those "types" of brands.


You're dealing with engine internals, no room for knock off parts. Buy the real deal stuff and never have to worry about it.

You can run any thing as a DD it all depends on your right foot. I have a Turbo R for 3 years now, no issues. On the other hand people build motors and blow them up in 3 weeks bc they cant keep the pedal off of the floor.

13's is a very very very easy mark to make. But think about your horse power wants/needs, rather then your 1/4 mile time.

 

Quote of the year for sure!

 

i had ctr pistons in my c5 it is roughly 12.0: 1 until i blew my motor
now i have 11.5 works pretty good for me

 

Seems as if a lot of people building reliable streetable motors are using 11.5:1 C/R.
