ok, i just spent a lot money on my 2000 itr i was just wondering how power will i actually put out, or if i can break the 12 sec barrier.
here's my mods:
2.ol scat stroker kit
skunk2 stage 2 camshafts
aem cam gears
dc sport headers
apexi world sport 2 exhaust
obx individual throttle body
supertech valvesprings and retainers
any kind of feedback would be great!!!

 

i dun understand... if you spent so much money the engine, why cheap out on the header/exhaust/and the ITB...

 

well i like the way the apex wsp2 exhaust look and sound. the guy thats doing my car said dc sport or vibrant would be ok for ythe header. an the obx itb wasnt bad so i just did it. its still in the process now so i can change the order. what do think was work better without spending 10 grand. i already spent 7500 on the setup now. im getn a clutch done and injectors and everything too!

 

The best thing would have been not wasting money on FWD 4cyl drag racing, but you've already blown that idea.

 

The header/exhaust are going to choke alot of power, especially on a 2L. I would reccomend upgrading those, if you want to reach the engine's potential. I dont think you'll come anywhere close to breaking 12 sec, unless you fully gut the car, bump the compression ratio, and run slicks. Even then, 11's wont come easily. You may also get better gains with a proper intake manifold and 3" intake setup. ITB's aren't particularly helpful for drag racing and they will take alot of effort to properly tune. It seems like you should have done alot more research before dropping 7g's on a poorly thought out setup.

 

Fail Wheel Drive

 

what headers or exhaust should i use. I should break 13 sec pretty easily though?

 

also the compression ratio is 12.6

 

Oh, I couldn't tell from the parts you posted. I would reccomend an smsp or hytech header designed specifically for a 2L engine. At least some type of tri-y replica. A 2.5" cat/ test pipe and exhuast with straight through muffler will also be mandatory if you want to see maximum gains. Im not really familiar with the apex system, but i was under the impression that it was 2.36 or something, and may not be a straight through design, but I could be wrong on that. I cant really tell you what kind of times you'll run. It depends on a lot of different variables. However, breaking 11's all motor is no simple task.

 

I did not even know that OBX sold ITBs

 

SMSP 2.0 header and appropriate 2.5" or 3" exhaust from Dave.

Go B20

 

lol, it is a b20

 

it is but, it still says b18c5 not b20 lol... thats the only reason why i did that. thanks for all the feedback man!!

 

Seriously... do people still e-race?

 

If you are going for power.
Ditch the header, exhaust and most importantly the ITBs.

Get a Skunk manifold and a 68-70mm throttle body.
Hondata gasket.
SMSP, RMF, DTR or whatever they are called now, ANR or a REAL header. Dont get a replica or you'll make replica power.
Matching 2.5inch exhaust to a nice free flowing muffler, I recommend vibrant, thats just me.

Is the crank a 95mm or a 89? What bore are you? Who assemblied the motor?

Also, to squeeze any type of power I suggest a Walbro 255 pump and a set of RC310s.
Who do you plan to get to tune it?

 

the crank in 95mm the bore is 81 1/2. im getting done by a shop called nexttech. and planning on getting it tuned by kingmotorsports. actually i did change from dc headers to vibrant. and once tuned properly how much power do you think i get at the wheels. thanks for the tips bro!!

 

I am making 228/158 with a 2.0L ITR and I am still using the stock IM/TB.

A few years back I bested a 13.4@107 on street tires. If I was serious about straight line I could probably break into the 12's with slicks.

OBX ITB's are not horrid like you would expect. In fact, they are made from the same production line as the TODA's. What size did you choose? The base B16/B18 size is 46mm, which is pretty small for a 2.0L.

I would suggest a better exhaust/header combo. If you search through the all-motor forum, there was a recent dyno test done with a 2.0L B-series. The new Skunk2 MegaPower Header won, by a pretty fair margin. I recommend a bigger exhaust like a T1R 70mm (2.75"), Skunk2 70mm, or a custom SMS or HyTech 3".

The most important part is the tune. If you have having King tune it, you should be fine.

 

Yes, you def. have the mph for 12s. Your stock tb/manifold wasn't extrud honed? Thats AWESOME power. do you have a link to your build?

I just don't like ITBs for cars shooting for power and are driven any on the street. Thats just a personal opinion.

I've read good things about King, so OP you are good about the tune.
Make sure you discuss with King your setup to see if there is anything that they watn you to do before you get dynoed.

 

i did the base b16/b18 itb. so u think thats not big enough? did you do the b20 bottom end or did you get a stroker kit? how power will i lose if i use the apex wsp2 exhaust. i really like that stock look?

 

On those parts :? Coulda bought another ITR for that money...

 

Nope. It is a stock manifold and tb. No portmatching or machine work.

Brief list:
85x87.2
12.2:1 CR
PR3 ITR head w/good valve job & stock ports
Supertech valvesprings/retainers/valves
Skunk2 Pro3's
Comptech Race Header
T1R 70mm exhaust
PW-JDM whale ***** intake
stock ITR intake manifold & TB
other misc stuff
Tuned on Crome

B18C block sleeved by Benson to 85mm, worked over GSR crank - 87.2mm stroke.

 

Yup you have the mph for it.

My build is simple.

2.0L motor on 11.7 comp. Stock crank and rods and using RS machines cast pistons.
GSR head non-ported. skunk2 stage 2 cams 440cc injectors, edelbrock intake manifold, camp1320 profab header, tuned on hondata on 91 octane makes 225whp. Runs 12.6@106mph. Weight reduction is only bumper supports spare tire and jack and rear seats. Oh and AC was removed. Yes my car had dealer installed AC at one point.

 

damn, seriously, cuz im selling my ITR for 7500




anyways, OP, dunno how much power Toda racing headers will give ya but i have one for sale, $650...if interested let me know

 

The TODA 4-2-1 would be a bit too small for a 2.0L

Excellent 1.8L manifold though
