best n/a parts

[stevenr816]

hey guys,
i have a '94 civic hatch with a stock gsr with hasport race mounts, stage 4 compition clutch and full omni coil overs.
it ran a 14.6 with 20 x 8 slicks with a crap 2.0 60' which isnt really bad times, but want to make it faster.

im trying to figure out the best mod for the money.
my list that i want to do is:
neptune tuning (that way i can launch at full throttle instead of guessing where to launch with the two step and the added tuning will bring out some power)
ctr pistons with gsr rods should put it at 12.3:1
port & polish
skunk2 st.3 cams
exhaust of some sort
skunk2 pro series intake manifold

im going to tune it first before anything, that way i can save up for everything to do it all at once. are there any better mods besides turbo and nos. i want to keep the cost low with the most power to $$$

hybrid intake maybe? the one by ARC. obvisouly some real good spark plugs and wires. maybe internals balancing.

how would balancing make hp?

[Type - O]

oh true, i was just thinking revs

[bryans_k20]

Practice will get you better times, no money new parts needed.

[<3bane]

k series.


or, HUGE cams. high compression. ported head. high rpm's. a $1000 header.


list goes on and on. but by the time you build a 230whp b series, you could have paid for a k20a swap.

a freely rotating bottom end puts alot less stress on parts. the motor also has to work less, yielding more power transfer to the flywheel.

[bryans_k20]

Yah, I highly recommend a k-swap. With those slicks and practice your looking at 12s, not too bad.

thanks, i didnt know how to word it

[bryans_k20]

^^Yah, a dry-sump oil system would help with that a bit too. Or a baffled pan would be the next best thing.

[DJ NeX]

wow....that's all I got to say

OK CTR Pistons plus GSR head = no bueno.

Go with JDM ITR pistons or something to that effect, pnp the head if you CAN afford a good job, and get some big ass cams and get a balleR header and you'll be happy.

[stevenr816]

why cant ctr's fit on a gsr head?
i know it will make ~12.3:1

balancing is also a good thing especially if you are going to rev past 9000

[imm0rtal]

why cant ctr's fit on a gsr head?
i know it will make ~12.3:1piston dome to valve contact, my friend. Well that, or something like that :P

Why go with an intake manifold when you can run ITBs instead? They usually make more power on B-series motors depending on the tune, so if you want more power there you go.

this is true, but really freakin expensive.
even with gsr rods?

[honduh_head]

do what you said in your first post...everything you want will net you good power...you could always throw a lil 50 shot on there just for good measure....

[Type - O]

what about boring it out a little bit?

[taggart_lumpy]

were you at speed world last weekend? black hatch

[stevenr816]

were you at speed world last weekend? black hatch

sure was that was me

[mixxxwell]

instead of CTR's go for ITR pistons. try looking into the JG edelbrock performer X manifold. along with a nice header like pro-fab, RAGE, hytech, or any of those 4-2-1 headers. along with some 310 injectors and TUNE. a nice size TB like 68 or 70 would do you nice. you can break200whp with those mods right there

Ok, let me set the record straight. Cuz everyone is all about the hearsay which I AM NOT. most people don't take into account the compression HEIGHT of the CTR aka PCT pistons.

Its 30.73!!!! HOLY SHIT! That's higher than most forged pistons. What does this do children? It jacks up the CR!

static compression ratio for a BONE STOCK GSR with the only variable changed being the pistons is 13.09:1 And that's WITH a 3 layer head gasket. Do you plan on getting this tuned on race fuel? If not, then I hope you like pre-detonation.

[I Hate Import Cars]

Personally, I don't see much of a point in tearing a motor down far enough to do any of the work you've described, and then not putting good parts back in. I'm not SURE, but I think all Honda rods are cast...Why don't you get a good set of forged rods? And I would def recommend balancing, if nothing else, for longevity of the motor. Forged rods and pistons, some good head work, and a well thought out port job by someone who knows what they're doing will do WONDERS for you. Then get a set of cams that is REASONABLE for your application, and you should be good. Remember, your bottom end just does the work. Your TOP END (head, cam(s), intake and exhaust) is where you make your power.

not to be cocky, but just do w/e I say and it'll be all good.

well thats why i started this, my friend told me that he talked to someone at locash and ctr pistons would fit and would be around 12.3:1 unless he did the calculations wrong.

but i am planning like you and i have suggested to port and polish, cams, intake, tune.

[DJ NeX]

classic case of not factoring in compression height to calculate compression ratio. That could prove to be very costly.

[locash]

I'm not sure if your calculations are correct, as I've done this combo a few times in street cars with no issues. I come up with 12.32:1 with CTR pistons, GSR block, GSR crank, GSR rods, GSR head.

I'd say to run it, but be careful on pump gas.

[DJ NeX]

I hear ya about running that combo joe, but most of these chaps that are doing motor builds are doing their very first motor. They need something that is easy to make reliable.

[Smoot]

K motor IPS cams wiht s2k valve train.

[taggart_lumpy]

sure was that was me

:hello: did you like my 29 sec run :hello:

i say stick with the ctr pistons but thats just me

[stevenr816]

:hello: did you like my 29 sec run :hello:

i say stick with the ctr pistons but thats just me

ya it was pretty fast!
29.621 @ 30.859 that mph is outstanding! :blunt:

what all do you have in it?
it was the black rsx right?

well you will be the one tuning it joe! ask josh tonight when you go over.

this will be my first for a honda, i have built plenty of toyota motors for my supra

[mottrhed]

omg this thread is retarted

1. yes ctr in gsr is about 13-1
2. 13-1 CAN run on pump gas with a good tune-dont be scared

3. besides the fact that it puts the static compression at 13-1, static compression means almost nothing. dynamic compression is all that matters. do some research and figure out what your dynamic comp will be with the cams you have chosen, and that will tell you what octane you can safely run. if you do end up to high you can bleed off some of the compression.

[stevenr816]

so if i run ctr pistons with a skunk 2 stage 3 cam i would be screw basically then huh?

what about running itr pistons in a gsr or is that even possible

:hithead:

[b20forlife]

i think it has to do a lot wit driving cause my stcok b16 in my eg hatch wit intake header and exhaust ran 14.5 constantly on cheap tires wit steelies

[DJ NeX]

ITR pistons in a GSR would totally be safe.

[stevenr816]

i think it has to do a lot wit driving cause my stcok b16 in my eg hatch wit intake header and exhaust ran 14.5 constantly on cheap tires wit steelies

well i know its mostly the tranny, the second gear syncro is going out so i take second really slow compared to the rest of gears cause if i dont it will not go in.

if you have ever heard me at the track there was alot of runs missing second.

[noVtecHERE]

itr pistons on a GSR is a hell of a lot better than CTR`s, henry said it best, they r detonation plugs... but hey do what u want, but i wouldnt go over 12.5:1 compression with forged on pump and over 12:1 on non Forged slugs, thats just a rule of thumb for me...
