What are your setups for these classes. H4 SOHC D16, etc.

Gearing choices and FD choices?

 

gear ratios are remained stock and FD, i would probably go with SRR

not sure about the rest

 

we've only been doing the ZC/SI combos on the cable trans for customers, but the Hydro trans, we havent done much hybridizing yet.

We will have more SRR FD in 4.7 and 4.9 for the SOHC Hydro in January.

 

ITA doesn't allow for "hybrid" trannys.

You can only change the FD not the gears.

I can't think of anyone in the NW that runs a FD, most of our tracks up here have some pretty long straits, so we end up running out of gear.

 

Our H4/ITS 89 CRX Si is essentially bone stock (176k) under the hood. The head should be coming off for a refresh. Tranny is also stock and does not have either an FD or LSD. The rules governing what you can do are spelled out in the GCR and NASA CCR-Don't start a build without them. Honda Challenge has enough classes to permit hybrids-but be very careful as it is super competitive and costly versus H5 or even H4 and ITA. The chassis of our car is where we put most of our effort.
Concentrate on seat time and you will delevop a better feel for what the car needs.
Happy holidays

 

It would be nice to have a reasonably priced FD for a D-series cable transmission. All the 4.78 FDs that I have seen are $950+. I know that SRR makes FDs for the Hydro version for under $500.

If I could get a set for my cable trans. in that price range, I would buy...

 

you should do H1 with a D series powered crx .... being exospeedish and all

 

We actually built a mean D16 motor for a customer in the midwest. I dont6 know if he's going to do HC though. the D16 can make 160-170 to the wheels. and with a CRX, it will be still competitive with the H1 cars.

Ahh so gears cant be touched.
Well the choices we have on the FD are the only thing these guys can use then.

Honestly, that would not be competitive in H1 anymore. Last year, maybe, this year or next year, definitely not. H1 has definitely upped their game this year and next year.... we can only imagine.

Not so sure. Bernardo Martinez ran a D series in his H1 CRX mid season in the WCHC. He was FAST. The combination could have potential if reliable.

It will be very competitive when they add 50-75 LBS to B, K, H series motors and leave the D series at 2000 lbs.

from the HC rules:

5. Transmission and Final Drive
a) Transmission ratios may be altered by substituting OEM Honda parts.
b) Transmission casing must remain stock.
c) Clutch and flywheel unrestricted.
d) Shift linkage and shift lever unrestricted.
e) Any final drive ratio may be used provided it fits inside the stock differential housing.
f) Any LSD is permitted.

 

the ECHC is a bit more competive, so maybe not. But WCHC isnt as big of a field so there is a better chance?

I thought the West-End boys won that Mid-O grudge match??

Hell, if someone figures out how to go yard on a 130 whp legal ITA D16, there will be a lot of open ears I'd think (mine would be a pair)

130 WHP is the thing of the past for the D16 ITA engine. I have seen a 135 HP Dyno sheet for a D16 that is ITA legal.

at the weight break they get, being 2000lbs and putting 160-170 to the wheels I think they can be competitive too. Reliable? Could be a different story. But, the lower weight is key. That would be cool to see. I wonder if you'd be able to get an EG hatch down to that weight under NASA rules. I think it would be tough. I think you'd have to use a 4th civic or crx to get down to that weight.

I agree with ITAIntegraLS. It's being done already.

A well known engine builder and tuner told me they could get 140+WHP (probably 150 he said) from an SCCA IT legal D16Z6 tuned with hondata. Now that is crazy!! And from the work I've seen them do I really don't doubt them. Of course if you have to ask the price, don't bother having them build it.

Whaaat?? I don't even know what Z6 means but it sure doesn't REMOTELY sound possible to make 140 let alone 150 out of a legal ITA D16 CRX Si Motor - if your engine builder found a way, then put us in ITS cause we have ALL been missing the big boat. I also don't know how you could legally use HONDATA on an ITA ODB0 car either.

I am sorry LS, we can get into the inaccuracies of dynos (or inconsistencies) but in my little bizarro world, there aren't any cars making 130 that I know of. But hey, that's a world of 110-117 hp SMs and sub-180 whp RX7s and all that - maybe I should have added that to my statement.

 

Z6 is a D16Z6 engine for a 92-95 EG EX/Si. half VTEC. not for the CRX in ITA, although it does fit as a hybrid. it lists as 127hp factory hp.

i believe hondata fits inside the ECU casing, making it legal.

OH trust me i have even seen that car run and its very fast. So fast that It beats a E36 BMW ITS car that is very well built. So you need to get out more.

you need to keep up with the rules!! 92-95 Civic Si's and EX's as well as 96-98 Civic EX's have been classed in ITA starting in '05. The d16z6 motor is found in the 92-95 Civic EX/Si and is OBD1 car, so you can use hondata.

i know of a guy around here that gets about 125 WHP out of his D16A6 in his CRX and doesn't have any problems winning. He's been developing his own car for a LONG time though.

Anyway, back on topic. Exospeed, I had bought a 4.7FD for my d16z6 build for my street car. Can't wait to try it out!

Oh so that's a SOHC car? Cool, didn't know that. Don't know my Z6 AY 88 codes either. But in the context of a SOHC Honda ITA car, I don't know many that are pushing 140 hp or even close.

there is a girl racer in Norcal that races a 90 civic hatch and she put down 130whp, HC legal


ooo and about the gearing, nothing can be to short, you will have to get a 5.23FD or something close to sacrafice any top speed, the top speed with that is still above 120mph
