    boosted F20B dohc vtec.

    hey guys just recently finished up my boosted F20B dohc vtec 100% bone stock. stock head, stock headstuds, stock rods, stock pistons. etc....

    i finished it up the end of this past winter. (2012) and april 14th 2012 i went to innovative motorworks in carlisle, PA to get tuned. and i was more than happy with the results. i did not expect it to go as well as it did.

    final numbers were 327whp 240lb ft.... this was on wastegate pressure at 7psi. on a bullseye power 57trim with a .70ar exhaust housing. and full 3" exhaust.

    parts used to reach this power goal.
    bullseye power 57trim with upgraded .70ar exhaust housing
    injector dynamics 1000cc injectors
    go autoworks Large front mount intercooler kit
    BRMS h22 twisted ram manifold
    turbosmart 38mm wastegate 7psi spring
    full 3" straight pipe exhaust.

    there are lots more but these are the essentials to a healthy and efficient turbo setup. im thinking of putting cp pistons on my spare set of f20B rods and putting head studs in and going for 400. i will upload pics of the car and dyno plots as well

    You should plan on forged internals sooner than later. The stock ringlands won't hold for long, and they could do damage to the sleeves when they break.
    Very nice numbers, though!

      Thanks yeah I'm deft. Looking to get custom 85mm pistons and probably keep the 11.1 cr and switch to e85 and turn it up a few psi. I've read and heard these rods will handle 400 so I think we will try it out

        Boost doesn't put as much strain on the rods as high-revving NA applications do, so they may be ok. Stock rods usually don't work with aftermarket pistons without some modification to one or both, though.

        To be honest, I don't think anything over 300whp is all that useful on a street-driven FWD car anyway! Traction becomes pretty difficult to maintain at that point, unless you're looking for drag performance.

            You need a limited slip and decent tires, I hook more than that in 2nd with drag radials on the street.

                It's a ram horn design turbo exhaust manifold made here locally in NC.

                  The 400 was more for drag racing and just running waste gate on the street. Car actually made 340 before we pulled a degree of timing. Now remember guys I don't have the stroke you guys have with the f22 hense why my tq is more like a b series.

                    I was taking apart a spare h22 I have and I noticed stock rod bolts on the h22 are studs with a nut. My spare f20b has 12pt. Rod bolts similar to the arp style. Hmmm... Odd

                        Ryan's build is already finished... He's just sharing it so everybody can get a bit of an idea on how he did it and how it worked

                          Do you have A/C or can it fit? I really like the look of this manifold but I definitely want to keep my A/C. I'm hoping our bigger bays can accomodate it compared to the Civics they were designed for,

                            I do not have ac. I'm not sure if it's ac compatible but you could talk to the guys at blue ridge motorsports they are great guys and I'm sure they would be able to help you with that

                              is this car still going? I just want to see how long stock internals last in f20b?
