Hey guys I got 95 eg8 and I'm gonna be swapping in a b18b1 and I'm planning on boosting it I wanna hit around 300-350 whp so here's a parts list that I will be using

Eagle h beam rods with arp bolts
Weisco pistons with a 10:1 cr
Brian crower stage 2 turbo cams,valves,springs,retainers
Skunk2 70mm throttle body
Skunk2 composite fuel rail
Ram horn headers
eBay turbo kit with upgraded intercooler
A wahlbro 255 intank gaspump
And it will be tuned on a Neptune Ecu
And port and polished head

Now the part I'm having trouble with deciding on is what cc's to get the injectors
I don't wanna Go to big and flood the motor or too small and lean it out
And the other thing is I'm debating on boring it too 84mm what do you guys think is that a good Idea or no

I plan on using the car as a dd and weekend racer with auto x track days and a couple drags I want it to be reliable so if you guys think that with 350whp needs to sleeved please feel free to tell all opinions thanks

kyden

you can't just bore to 84mm. that requires sleeving.

why build the motor and run an ebay kit? i would rather skip the build and buy a better turbo setup IMO.

Whipskicksn40s

I though you could bore up to 85mm without re sleeving
And I know a couple that run eBay turbo kits and they said they are fine as long as you upgrade the intercooler and use better oil lines

This is the truth +1

So u can't bore out stock cylinders

To 81.5mm yes
Bigger than that I would resleeve, why? Because the cylinder walls will get weaker if you don't resleeve it.

As for your turbo kit, upgrading your line and intercooler does not save the internals of an "ok" turbo.

Co-sign... sorry, I just had to

I'm not gonna try boosting 30 psi with it just enough to get to my goal

Doesnt sound like you did much research to be honest. If your trying to achieve 300-350 hp, then the cams and port and polish heads are overkill. Also the pistons you want is overkill. Get 9:0 compresion pistons. As a matter of fact, if you just buy a legit turbo kit, you will achieve those numbers very very easily and at low boost pending the turbocharger you get. Regardless you will hit those numbers. UNLESS your trying low numbers first then work your way up in the future then fine but if your just trying to hit 350 max, then no need for all that mess.

In regards to the injectors, get some id 1000's. No matter what size injectors you get which will probably be 450 cc at the minimum, you have to get the car tuned. Getting to small injectors or too big of injectors is not going to lean or flood the car. For example, my rc750cc are maxed out 90% duty cycle (404hp). If I want more horsepower, I need bigger injector. At the same time, these were the same injectors I used when I first tuned the car at 264 hp, cant remember the duty cycle. All I'm trying to say is you cant flood or lean out the car because the injectors are too small or big..... Its all in the tuning. Your tuner will calibrate all that mess that I know nothing of lol.... Hope I was clear....

Whipskicksn40s

All I want to know is what size injectors to run not get dawged on cause I'm not gonna buy a 3k turbo setup

BigZeke5

For the parts your going to be using, you might as well get ID 1000'S. Good luck...

Whipskicksn40s

Thanks big zeke that's what I needed I was kinda shooting for over kill since it is gonna be a dd make it more reliable but what kind of power do you think I can hit with the set up I listed

BigZeke5

You dont need to bore out. Leave the bore as is. A far as horsepower with what you listed, I can see 400 easily and thats a low number because I have no clue what size turbo your getting which you didnt specify...

In its current state, this build has FAIL written all over it. You need to research, read the Forced Induction FAQ, and re-evaluate your "plan"

Whipskicksn40s

It's just gonna be a small t3/t4 A/r .63

BigZeke5

Not for nothing, but going back to what I said earlier, doesnt look like you researched. For what you want and the parts you are using, its two different scenarios. Please do yourself a favor and do research before you blow money away for real. Just being honest, not trying to dog you. Just speaking from expierence, thats all.... LEt me start you off with reseach. Here is a link and just read....

ID1000cc could be used but not necessary. Yes, they are normally easier to tune than Rochester/Lucas injectors (like RC and "Precision" injectors), but for 350whp even the ID725cc injectors would be more than enough, or 660cc injectors of Rochester/Lucas type.

You have some options in that regard.

As for the eBay kit, don't bother with any of it, especially the turbocharger if you're going through the effort to build the engine.. (81mm can do just fine for 350whp without having the need to resleeve) save the "boring" money for better turbocharger components from good companies.

BigZeke5

It was just a matter of time when you were gonna write something lol... Hopefully he listens....

Whipskicksn40s

Since all you put down the eBay kit I'm just gonna go all motor can all motor hit 350 Pretty easy or no

Stock motor 1000$ eBay kit good tune 600bux get 325 np

Hell to the no
It's much much more expensive to hit 350whp all motor. With an ls it's not even possible, but I could be wrong...but I seriously doubt it

BigZeke5

350 hp all motor is very very expensive... Once again your asking questions that are already answered on these forums if you just read some.....

Schister66

Must...resist...urge to lock....

Logical next step...dont bother adjusting your plan to accomodate the new information we gave you. Instead, do a 180 and head in the complete opposite direction.
