    What's up, well I'm getting some work done on my b18c and wanted to get some feedback on some opinions...this is what I'm doing what's your thought...

    81.5 RS or ITR pistons , bore and hone the block, micropolished crank, ARP rod bolts, ACL race bearings, new oil pump, water pump and timing belt,.......ITR Headers, Skunk 2 manifold, itr valve train

    Would this do a big difference???

    What are you building this for?

    Daily driver?

    You dont need ACL race if you are trying to just do a DD, ACL Duraglide will be fine or OEM.

    I would just go with a hytech copy header over the ITR.

    OEM pistons if possible.

    Add a valve job.

    you didnt mention cams...

    If i was to do a DD gsr motor, i would be more inclined to leave the bottom end stock or near stock and put more work into the top end.

    You will not make much power without increasing compression.

    He did mention ITR valvetrain.

    The only things in your list that'll stand a chance at increasing your power are the pistons, ITR header and intake manifold- and they really won't give you that much more than you had stock. If you want to be fast all motor:

    Punch block out to 84mm bore minimum
    89mm crank (B18B, B20)
    13:1 compression with coated pistons
    Huuuuuuuuuge aggressive cams
    ITR LMAs
    Stiff ass 10k valvetrain
    Ported head, Alaniz and Portflow do great work, among others
    Build your own intake manifold and tune the runner length for 7k-9k resonance, tune runner diameter to max flow at redline based on your head flow numbers after porting
    Normal supporting mods: breathers everywhere, adjustable everything, baffled pan, ported oil pump, giant throttle body...

    Then tune the hell out of it with someone you fly in from elsewhere in the country.

    :D

    lol cal, thats a beast dd motor!$$$$$

    ITR lmas??? how long have you been away from the b's?

    Honda only sells the spring type now similar to the prelude, nsx, and s2k. I used them in my old gsr build, they are about $230 for the set from honda. They were great with the pro 1 cams I had. I miss that motor and it wasnt even over 200whp.

    Probably up around $10k.....unless you do all the work yourself. You could send your short block to ERL for about $4k and get back part of what was listed. You would still need to do all the work on the head which, would easily run several thousands. Portflow is around $1k just for the basic package that wouldnt be adequate for what was listed. Cams, tuning, tuned manifolds, and on and on $$$$.

    all motor is the expensive way to be slow.

    I would rather have a k swap.


    Hell, I have about $3k in my D15 race motor thats going to be lucky to hit 105-110 whp meeting specifications for the class..

    The real question is can you do this yourself? If not I would seriously look into turboing the stock gsr with a meth kit. You should see 300 whp.

    supertech sucks, do not use....read my gsr thread for more info on them.

    some of that advice is very vague:

    fuel pump? you didnt mention size? at least a 190 and up

    throttle body size big? you can lose power by just throwing the biggest thing at it. 68-70mm matching the intake manifold is a good place to start.

    jg manifold based on what? AEBS is teh best bang/buck

    s2 pro 2s ??? really? on 11.5 compression?

    no porting to go with that setup?

    Truth is I'm not mechanically inclined...i have more than 3k but I'm trying to keep it around $3k...my friend owns a shop and I get hooked up...i already have walbro fuel pump, gsr head and ctr manifold...and just curious what it would cost minus those partsand minus the tune

    Dude we use supertech on big boy power plants nothing wrong with them

    255 walbro

    Yes really I have seen them make great power on 11:1 comp

    Jg Mani is great for this economic build

    Seen them? I ran this setup we are discussing except with pro 1s at around 11:3, they needed more compression. Skunk2 even tells you recommended compression higher than what you have said.

    Supertech sucks, period. CS sucks and so do their engineers, I had pieces of their retainers floating in my motor. The reason their engineers gave me was my valve springs werent stiff enough causing float...until I told them they were supertech valve springs and then they didnt what the hell to say. I was stuck with a blown motor.

    I havent heard or seen, I have done.

    You cant just throw a wish list together and have it work optimally.

    Lol dude you know nothing about me.

    Its OK I'm not about to trash this guys thread. I have built a good amount of engines and I know what I'm doing, I should also mention I have full access to a dyno and know what works and what dose not.

    Now I don't know what to do...lol...I certainly don't want to invest 3k and end up with a blown motor...you both seem knowledgeable enough to me, but I'm stuck on which way to go now...
