my other car i drove for 2 years has been natural aspirated and now i wanna go forced induction but i dont know that much about it
i recently bought a 99 si it has a lot of miles on it 118xxx but runs strong and i was wondering some questions
would it be alright to run a turbo on all stock internals at low psi around 7 or lower for everyday use would the motor last long or would it blow
what are some things i could do to build it up with out completely taking my engine out and messing with the block or whatever like some cams
please someone help me out so i dont eff my engine up

 

I hate to do it but...



you'll be glad you did

 

Do a compression & leak down test on the motor.
Perform normal maintenence on the motor (valve clearance check, cap, rotor, fuel filter)

Do reasearch on turbo kits/components/fuel management etc.

Concerning fuel management start by reading: http://www.phearable.net/tech/efibeginnerguide.html

Good Luck.

 

thanks mtber.
anyone else have some helpful tips

 

just build a motor dude, i got the same civic as you and im not putting my kit in till i buy my built block, the kit is sitting there collecting dust.... ull have garanteed reliability this way and if somehow your turbo setup fails, you can always put your NA back in there, or build the NA high comp while you run on the other block... and if u like the boost buy a crx and drop it in... and 15,000$ youl be sooo cool!

like me

 

 

I ran a SI motor for over a year at 14lbs of boost with a greddy18g kit on the vafc hack.

That being said. I recommend a thicker headgasket and a conservative tune with neptune. For 7psi you will be fine, even 10. You will only make maybe 50 whp (depending on the turbo...big variable there) The weakest point on the b16a2 from my experiances is the ringlands, that is what finally went on mine. I had stock compression though. People say sleeves but any sleeves will give with detonation.

Other than the headgasket, i would invest in fuel upgrades. (ie. fuel pump, static 1:1 fuel pressure regulator, etc) to compliment neptune. I don't know if any one local uses or tunes neptune yet....they should. Cams aren't really needed, unless you wanted to go with a gsr exhaust cam (cheap and effective)


Searching isn't allways best as i find alot of innaccurate info being posted. Hope this helps!!

 

Posts like this....a built motor doesn't gaurantee shit. Except hurt pockets. Most likely your turbo won't fail your motor would.

 

engine wise, all I would invest in is, a ARP headstuds and a cometic .043" headgasket. The gasket will drop the compression to ~9.8:1. Crome and uber work nicely, you just need teh right copy.

Install the turbo kit, with some 450cc or bigger injectors then, goto me or mtber and get a good street tune. With a good tune ~250whp is VERY safe on stock internals. That is much more than 50whp.

Casper your ringlands cracked because of the vafc hack, it doesn't remove timing. timing causes detonation, which leads to your ringlands cracking.

 

My ringlands went with hondata too? Tuned by inline pro in VA.

I stated 50whp because he said 7psi...just a realistic reference point. I don't see many people making a hundred whp on 7 psi, without a rather large snail.
