i just got my 96gsr back from abacus racing yesterday, i was having cams, IM, valvetrain, ecu, and headwork done, with the other bolt ons i already have, it dynoed in at 187 at 8k rmp...i want to atleast 200whp next summer, the only thing i have left to do is the bottom end, is it possible to get 13+ hp out of the bottom end by raising the compression? i heard the stage2 skunk2 cams need higher compression to make their peak power. maybe sleeving the block and boring to 84mm? or would that just help with torque?, thinner headgasket? i already know im gonna switch from my skunk2 ecu to hondata, but im not sure which one, 100s maybe? thanks for your help in advance!

 

raising compression does nothing but make power.

 

your skunk2 stg 2 will like the higher compression.


abacus huh?? chuck and shad are good people....

Yes! Good poeple indeed

 

Coult you give the exact combination of the parts that you are using to reach your current numbers? Then a good upgrade route can be proposed based on whether of not you need to get rid of anything that you currently have, or which items need to be upgraded.

i have an AEM CAI, S2 IM, DC 4-2-1 header, custom catback with OBX hi-flo cat, S2 camgears, S2 stage 2 cams, S2 valvesprings + retainers, S2 ECU, unorthodox SS pulleys, MSD 6AL ignition, clutchmaster flywheel, ACT clutch, and some magnacore sparkplug wires. i also ordered a ground wire kit, that might give a HP or so, i read some good articles about those freeing up HP. so the only thing i have left to do is the bottom end i guess. i dont think a FPR would help right now cuz im already running rich with the S2 ECU, but id switch to hondata (100s??) next summer along with the pistons and rods (wiesco and eagle??), chuck said he'd micro polish the crank and deck the block along with boring out the sleeves to 84mm...any other suggestions? i guess i could take off my power steering belt to free up a couple more horses...

 

I'm not sure how you're running rich with the stock injectors(since you didn't add in that you're running anything different), you've most likely maxed the injectors out. It would have been nice to have decked the head when you were having it ported, but you can still use a thinner head gasket to gain some additional compression.

Advice, my opinions:
DC 4-2-1 - sell it and upgrade to a header with a 2.5" collector, budget is the DC 4-1 JDM clone
OBX cat - not so sure on that one, but no personal experience
MSD 6AL - no need, sell off
Magnacore wires - stock work great, no need, sell
grounding kit - I did this, no gain, but headlights are brighter
FPR - if getting a Hondata no reason to spend the $$, upgraded injectors are better
Power Steering Belt - 3-5whp gain
larger injectors - get some before you install the Hondata, you'll need the fuel

84MM - required new sleeves, i.e. Golden Eagle, RS Machine, Darton, Benson...also required new pistone, new rods, not the cheapest way to 200whp NA

Decking the block - no reason to deck block unless it's warped

Take my information with a grain of salt, you need to do research on your setup as a whole, and find the parts that work best with each other.

Do you by chance have a copy of the dyno plot that you could post up so that we can see the shape of the curve? What kind of a dyno did you have the car tested on?

Hope that helps a little...

you can gain 4-7 WHP by switching to a DC JDM 4-1 header.

If your going to "do" the bottom end they will deck the block. That's part of the blueprinting process. Gotta run and watch World Challenge////

 

If I was in your position the ni would get a hondata intake manifold gasket, then ditch the headers you have and get one that makes good power like a hytech, smsp or a DTR header w/ a good high flow cat, those mods alone could get you to the 200 mark ! Then as far as the bottom end goes you could get it bored out if you have the money, if not then just get it rehoned get it balanced, then stick some rods in there and the then the the best part some jdm ctr pistons. This combo with tunning and you will be well over 200, i say this cause i have seen it many times. It's not cheap but it sure is fun to drive a 200+ all motor b series

good luck man!!!

 

get skunk2 type-2, IB spec ultralite pistons, IB spec ultralite rods, sleeved... my compression is 12.8:1 dyno at 222WHP 158TQ. high octane of course.

are u running stage 2 cams on stock compression? just want to know cause i am thinking about running stage 2 also.

 

what size injectors did you have in mind? rc 440???

 

Yeah I was there when Shad was putting it all together. Shad told me the dyno #s yesterday very impressive considering only a small bit was milled off the head. Some more compression and #s will raise, lighweight pistons and rods and HIGH CR! Also those #s are right there with some ITRs with Toda cams that have come in there. Also another poor man's ITR fully built with headwork everything made the same #s with headwork but through the exhaust. So some more compression and those #s will be even moreimpressive.

 

go for some ctrs that should get the extyra hp youre looking for..

 

you do not need to go 2.0L (84mm) to reach 200whp.

get hondata.
get decent intake/exhaust/header (get rid of your dc 4-2-1)
11.0+ compression.
tuning.

 

does anyone know where i can find a jdm dc 4-1 header for a good price?? also, i thought my stock injectors (210cc i beleive) would be straight up to like 230whp or so, but i could be wrong, i think rcengineering.com has some formula to find the right size injector, ill check it out, but if anyone knows a good site for that header, let me know, thanks.

You can get any size injector if you are going to use Hondata. The stock injectors are 240cc. As for a header, take a look at some on this board like Smsp, Drt, Anr, Header tech, these headers are superior to a usdm/jdm dc header.

Thanks Ausmith...I knew that there was something else, just a long week at that point and couldn't remember everything

true

but it is gonna be hard to get 13 whp out of it u should have went with toda spec cams and toda pistons

 

i was just researching hondata...for my setup, im not sure which would be better...the s100 or the s200. any suggestions?? also, i had someone offer to sell me a jdm dc 4-1 header for 275, is that the same as the regular jmd 4-1 header? or is it different? i heard good things about both.

 

i did the same setup as you but i have stock headers stock cat. converter stock ecu.. and my car is lagging like a mother on low end and vtec.. how much did u get your skunk2 ecu for

 

i had to buy an OBD1 off a civic and that was like 130, then to get skunk2 to chip it was 285, so all together a little over 400, but man, if i could to it all over again, id go with the hondata, i dont know what i was thinking, i just thought hondata was like $1000 for some reason.

 

I know, all the junk people can do with Hondata now a days, and its so cheap. I just want to get my motor together so I can buy a Hondata, haha.

not necessarily. there is a cheaper route..........
CTR pistons added should get him right at 200hp or close to it.
the solution is to tune, tune, tune. air/fuel/vtec xover/everything.

look around for a header. u can find a used one nicely priced. look for JDM 4-1 header also. i got mine used for $285 shipped in great condition and had it coated by jet hot and it looked brand new.
