not even mitch. i am glad you went with a different turbo instead of that ebay 20g. with a turbo pushing that much you might want to lower the compression to around 9 just to be a little safer. its up to u its ur car tho.Quote:

Plus the size of the turbo will not effect anything 10psi is 10 psi its just that on that turbo its going to have more cfm meaning more efficient 10psi over a smaller turbo.
Props to you for doing what you want, don't listen to all the haters, they obviously don't know any better.
Aww shiet cats out of the bag! That 60 trim in your light 7g def equals bricks to be shat!
Running a higher compression with boost isn't bad, it definitely helps to eliminate the "doggy" feeling with low compression until it starts to make boost. If you plan to make it a DD vehicle with boost then yea, lower CR will be good..but really no poit in going lower than 9.0 or 8.7:1 at lowest to try and keep some power until it hits boost.
The only thing you need to make sure of with higher CR and boost is that you have a set of forged rods (no duh lol), and a meth injection system for the reasons already stated. For this build, and low boost like 10psi it will be making decent pulling power before it hits any boost, then when it hits boost it will be a monster.
Just out of curiousity, what meth injection kit did you end up going with, and how much did you have to spend?
how is this being a hater. a high compression motor on little turbos have failed more often than lower compression motors and honestly, why run a high compression motor with a big turbo at low boost. you will make power, but the tune has to be 100 percent on point and with meth how are you going to tune it. my buddy tunes his xr4ti with taking a little meth into account so if he runs out the tune isnt so far off he blows it to pieces.Quote:

and i understand you not wanting to take it apart again its a bitch. i wish you luck mitch, plz get this honda fuck outta here even if he is ur friend
lol your aggressive attitude is whats making it seem like major hating instead of making sure he knows everything.
the honda kid is pissing me off with stupid comments. i agree with what mitch is saying about not wanting to take it apart and he weighed the options. i respect that and if he knew everything and went this way good for him i wish him all the luck as i want him to get to his goal, but this honda kid is uselessQuote:

exactly. thank you. 9.0 is the highest id ever go for even a mid sized turbo and you will spend days making sure the tune is spot on so you dont blow it up. cuz if you do.. it DOES have to come back apartQuote:

If you don't have anything productive to say to Mitch (which you've shown you don't know shit about turbocharging or even cars in general) don't clutter up his thread :021:Quote:

I dont see why everybody is worrying about me running a high compression engine with boost, i know you guys are just trying to help but all the stuff i have read with the meth kit people are running v8's boosted with 11.5:1 with out a problem all they do is change the nozzles out to flow more in.
So the comments about the honda kid not knowing anything made me laugh cause his ls1 turbo swapped mustang that is tuned by him, so until someone can prove him wrong don't refer to him as the honda kid call him "THE MAN" LOL
But on a lighter note he has been playing with dsm link, and for my setup is creating some base fuel maps to try out so stupid honda kid is the one that is going to be teaching me how to tune.
The only reason people are making a big deal about it is because nobody that I am aware of on TGC has even gone above 9:1 CR for a turbo setup. They are running low boost numbers on higher CR builds, but it's not something common to a lot of people and they just don't understand that the tuning is what makes the high CR and low boost work.Quote:

It is a really good system since it has a controller to set when each of the 3 nozzles will kick on based off your EGTs. We used to sell the Snow kits here a few years back but found a lot of people were having issues with the pumps failing, that and they didn't have the adjusability what most people wanted.
The whole thing comes down to keeping the knock down and pre ignition problems due to the higher CR with low boost. the intake temps really need to be down, but water injection or whatever you like to use will do it, plus you have a huge ass intercooler

Lol yea its good that i got that fmic now with my new turbo i can actually use the damn thing.Quote:

I'm turboing the SOHC at the stock CR of 9.7:1 i think thats the Compression of the 8G 64.
according to the manual it is 9.0:1 for 8g and 9.5 for 7g
