what should i do to my stock ls integra when i put turbo on it? and what amount of boost can i run safely? i put turbo on and just blew my motor but, i dont want to do the same thing again. i cracked my pistons between the rings. also if possible can someone tell me what caused this? thanks i really appreciate the help.

 

You dont have to do any engine preparation internally to run 10 psi or so safely.
What you need to do is make sure the turbo system is working 100% ( I mean Vacuum lines are all mounted right, etc etc)
Making sure you are getting proper fuel is more important than any engine mod you can do. Also retard the timing a bit (TO the lower end of what is reccommended from the factory)
Use high octane gas (ALWAYS!)
and DONT EVER use platinum plugs, try something like the NGK-BKR-7E, gapped to .030 or so.

ok thanks for information. i was using platinum plugs and not enough fuel last time.

 

No prob man, Those are some of the most important things to overlook.
For Fuel I use a holley 255lph intank pump, (Very easy to install) The FMU that comes with the RavHard kit, 310cc injectors, and the VAFC ( I guess you could use the SAFC)
Even still if you dont have the SAFC, you can just do the pump and injectors, but youll probably run a lil rich on the low RPM side.
Let me know how it comes out !

 

so, if i have a safc i wont have to change the injectors and fuel pump?

 

Sorry I didnt mean it that way. The bottom line is to not have your system be starving the engine of fuel. I reccommend getting all 3, but if you have to pick an order of importance, because you cant get all of them at once, I would say, INjectors first, then Pump, then the AFC.
The AFC is going to help you control the injectors, but you need the inj and pump to bring the fuel.
Many systems have been set up using this method, and it should work fine for you too.
If you get the pump and injectors, 310 or so, youll notice the car will be running rich at idle, so the AFC will help you there so you can lean it out at idle, or where ever else is needed.
You can always Email me if you have any questions along the way.

 

ok thanks. i'm putting it back together tommorow so i will probably get back in touch with you. also do u know what the stock injectors from a 2001 eclipse are i have some of those and some from a turbo mazda.

 

Dont run "10 psi or so" with an fmu and an intank pump.

Dude, its really up to you , or whoever wants to take the risk, there has been more boost run on VTEC engines than that, with this setup.
Ive been doing it for over 2 years, sure engine management would help, but the point is to deliver fuel at a specific RPM, and enough of it .

 

Have a beer, and Happy boosting

 

heh, gimme a ring when you blow your motor. Have a couple benji's handy when you do.

 

Thanks Bryson, You too man,
And Tony , stop the hate dude. If you have something constructive to say thats cool. Im just giving you my experience. I did it right the first time, unlike most people who bust theyre ring lands, because they pay no attention to Timing and Fuel, and think a build up, or a $3000 engine management system will automatically mean a perfectly running car. Heres a beer for all of you

 

From Experience, LS motors can handle 12 PSI easy with proper fuel management.

I now a couple people running that setup for over 2 years, no problem.

 

Thanks for the back up BG, those guys from Inline pro do some sick stuff with their cars, and stock internals.
Too bad most do not have a good reliable experience with boost, all it takes is some research.

 

I was running 10 psi for over a year on a bone stock LS motor with 310 cc injectors, Bosch fuel pump, and an 8:1 disk in the FMU.
