    so ive decided to keep the altima and fix the minor damage....and since the crx is uninsured and not starting i am going to get it ready for next years drag season...

    the block is getting sleeved and the cr is going to be set at 9.8:1 81mm (for rebuilds and maint)....i will try to implement a 2 stg nitrous system but that is another thread.....this build will be on a small budget....so i've decided to use a holset turbo....running 15+psi...and i want to try to use the nos to spool the snail

    i've been reading this thread on HT
    http://www.honda-tech.com/zerothread?id=1225182&page=1
    and hotrex hooked me up with some one in HMT that knows about these turbos...

    but this is my home forum and you opinions hold more water...


    so the HX35 looks like it would be the best choice...but the hy35 is also a good candidate....but the HX30 would also work and the 40 series is huge.....what would be the best choice for my set up...

    from the pics that i have seen they are all t3 flanged but some have a divided inlet...what is that? and can i bolt it up to a reg t3 flange....


    discuss.........

    Here are some HX/HY-35 maps. Boost pressure at 20 psi (pressure ratio calculated from that), with cfm plotted from 500 to 8000 rpm. Pre-2003 <span style="color:#33FF33">HX-35 in Green</span>. 2003 - 2004.5 <span style="color:#000000">HY-35 in Black</span>. 2004.5 - <span style="color:#CC0000">Present HY-35 in Red</span>. This is for 2.0L of displacment. (Excuse the updated graph, as I have some small changes yet to make to the fonts and scales, but the maps are correct.)

    they all have a standard t3 exhaust flange but are split for a twin scroll effect. The best idea would be to make a twin scroll manifold connecting 1 with 4, and 2 and 3 if i am correct, i might be wrong. But any manifold with a t3 flange would work

    the hx35's and hy35's ive seen all over ebay, i have yet to see an hx30 personally which was what i was looking for when i thought about boosing my stock b16

    they seem like they have tons of potential though.....

    from what ive read on H-T HY35 for single cams and HX35 for duals. also from what i understood the HY35 has a smaller exhaust side from the HX.

    How do you get the airflow for a certain engine...the only thing i know how to read is a stock ls, because the dude on H-T specifically said what the flow was.

    a hx40 on a b16a will not spool for shit.

    i still suggest the hx35. guys are making 400 plus with ease.

    thats from the my first post..

    .and is an lsvtec engine..not a b16.... its track only set up using c16 fuel..i might consider boring the block to 84 but with the nitrous and turbo i think i want the sleeves as thick as possible

    so i'm going to buy this turbo and some other stuff from this seller..

    WH1C

    http://cgi.ebay.com/ebaymotors/ws/eBayISAP...TRK%3AMEWA%3AIT

    then its going here for a rebuild

    http://www.htturbo.com/dodge/

    i've decided to purchase a gsr block and get that sleeved with a knife edged ls crank...and a custom ramhorn mani...an p&p my b16 head

    but until then i'm using my el cheapo manifold, buying a 40mm wg and a custom 3" dp (prob made by hotrex) and boosting until the old ls block gives up....

    Formby: have u seen one of these turbo's? the hx35 has like a 9" wide compressor housing, its huge, i dunno but unless your pushing for low 9's with spray and all that jazz id beleive the hx35 would do more than enough for you

    I just got into the 12's on 12 psi with my Holset. I ran a 12.88 @ 110 mph in the quarter. I had a 2.00 60' on drag radials. Here is a quick setup list.

    LS/VTEC with ported b16 head
    Log style turbo manifold
    turbonetics deltagate external wg
    70mm throttle body
    intake maifold port matched to head/tb
    Large fmic
    blitz dd blow off valve
    2.5" to 3" downpipe
    3" exhaust
    Holset H1C turbo
    Crome stand alone with base tune
    (car needs tuned pretty badly)



    so i'm good
