Hi im interested in going turbo i have a 94 ls engine was planning to rebuild the engine with a new crank rods pistons ring bore it .020 or .030 over with a thicker head gasket so i get a 8.5:1 or 8.0:1 compression so i can run more boost does this sound right to you guys im not too sure about turbos so let me know thanks also a 35 shot of nitrous thanks

 

if you're already going for new pistons, I would get inverted dome to lower compression instead of thicker head gasket. If you go with thick head gasket, that will be your weakest link

 

Also why so low? I wouldnt go any lower than 9 to 1 compression...
You know more boost doesnt always mean more horsepower...
Someone running 10:1 compression ratio at 5lbs of boost will make the same as your 8:1 compression at 10lbs... thats just an example may not be totally accurate, but it gets the point acrss..
The only reason to lower your compression ratio would be so you could run lower octane gas without pinging.. Or unless you just wanna brag.. I run 20lbs of boost!! w00t...

 

if you get a thicker headgasket your timing will be off anyways. Just go with better rods and pistons that are around 9.0 to 1. You don't want lag to be a problem either. You could just stay with your stock block too depending on how much boost and power you want to go with. 10-12 psi on a stock ls is fessible. late

A lot of people are making around or over 300 WHP on the stock block LS. Tuning is the key.

Do you want a race car or do you want a street car? Just Keep it simple and save your money.

I couldnt have said it any better. Before you even start, make sure you know what your goals are. My goal for my VW 2.0 turbo was 200whp and thats what my setup reflects. The best way to get power out of your turbo is to tune it properly. Hell there's a dude on here that made like 400whp out of 10psi on his B18. Tuning like that is sick.

And as for your compression ratio, dont go below 9:1 unless youre running an insane setup. I know a friend who has a bored out 3.0L VW VR6 turbo and he's running 8.5:1 compression, he wouldnt even consider doing 8:1 tho. 9:1 should be more than enough.

 

I am going the same route right now as well(stock B18b, turbo). I am going to run between 7 and 9 psi. I plan on using a cometic headgasket and ARP head studs. Everything else will be a bone stock B18b longblock. LS_REX runs consistant 11.80's on 13 psi w/ a best of 11.52! His longblock is stock w/ 200k mi. on it!!! Tuning is key!

lol ok mr. highway warrior jk

 

wow wow wow...isnt anyone gonna tell this guy he doesnt need new crank? honda crank can handle over 700 hp. and i know u aint going that high. some of the drag car guys are still using stock honda crank. dont waste ur money on new forged crank and spend tht money towards ur turbo.

Maybe his crank is damaged?

maybe he meant he wanted to snort crack?

 

I think i'll be satisfied tuned at 10 psi, but we will see what whp I get..

 

why does everyone judge everything by PSI?
Its not how many lbs of boopst your running its how much horsepower...
you can run 5psi and make 250hp or you can run 10psi and make 250hp...
its all in the setup...
But because it sounds cooler to run 10psi youll go that route..

 

Im in the same boat as you man..........
im doin my BEE ONE turbo in a 93 civic coupe also
but Im runnin stock internals but not a lot of boost.........
i put together a turbo kit myself
im usin a aireasearch t3
on the side i got a A1 ls head that im gonna port and polish and im lookin for a block now
i thought about ls vtec but i don't trust it
i wish i could run 12's but my goal is a quick little bastard of a car
im thinkin about taking off my Apex N1 for a flowmasters because i heard its
nice and quiet but some one give me their opinion on the flowmasters whoever has it on their civic..........VROOOOOOOOOOOOOM PHISSSHHHHHHH!!!!!!!!

How does a thicker headgasket become your weakest link?

 

thanks for all the feedback. i was planning to have a daily driver i want it to be fast though like everyone else on this board but i dont know what to do im not too familiar with turbos and high performance tuning so i came here for help and you guys did help alot i know that a stock ls can run 8 psi but how many horses do i really gain from 8 psi? i have no clue also i think im going to go with 9:1 compression the reason i wanted a new crank is because it's lighter i though the lighter it is the better so now im stuck once again i would like to run 12 psi what kind of set up would i have to run also looking for 300whp please let me know if it's possible and how much money are we talking about thank you guys

 

search and read, you'll find all the information you'll ever need to reach your 300whp goals. remember everything has to do with tunning and flow. if you've got parts that flow nicely together and you've got a great tuner, then 300whp is a cake walk. and if you've got questions, ask.

 

i'm doing the same thing in my crx (LS-T) and the block has already been bored .20 over. I noticed that he was saying he might bore his .2 or .3, so i'm gonna ask a question for both of us.....

Will high boost be safe on the LS block with the stock sleeves bored .20 and no aftermarket sleeving kit?

 

it's all in tunning. if i remember correctly...TITAN MOTORSPORTS on here is running 16psi on a stock LS. i forget what turbo it was but i'm sure it's in the t3/t4 and above category.

 

I run 14psi daily on my stock LS and when i need to i run 17 for a run or 2....

i dont even know where to begin i knw i would like to hit 300whp mark but what kind of turbo would i need and what kind of tuning will have to be done in orderr for me to reach that goal?
