'88-'91 Honda Civic H/B (4 speed, throttle body injection version)

Fast out of the box, no carbuerator crap to deal with, parts, parts, and more parts available. Also look cool!

I have a friend who just built one of these. The car handles like it's on rails, but has no a$$. He is getting killed on the straights, third gear is a dog and 4th is almost useless. At the very least it needs a gear, but where do you find hop-up parts for the 4-speed? I have seen the older generation run well (85-88 I think), but not the 88-91.

R2 Racing, what do you know that he doesn't know, and would you be willing to share? http://Forums.ImprovedTouring.com/it/smile.gif

A '88-'91 won the 2001 ARRC in ITC.

Yea, and one was leading and about to win the ARRC in '02 before he pulled it off with a minor oil leak. They also hold a couple of the track records here in CenDiv - broke Mid Ohio twice this year. I don't think they get down the straights quite as fast as the '84-'87's but I certainly wouldn't say they get killed. They just have the cornering and braking ability to run circles around the other cars. Usually you can get a good enough run out of the corner to make up that difference.

Your friend will see a big difference in getting a final drive. Just get one out of an Si box and try running real little tires (225/45's). Also, the computer holds some power. Who's your friend anyway? Where are you guys located?

[EV]

His name is Rob Luke DC region. Took his second school this past spring. Here is a link to some pics at spring drivers school. It't #78 http://www.wdcr-scca.org/photos/03SpringSchool.html

I am sure an engine refresh would help, it's got alot of miles, and the ecu is next on the list. The car was rented for a couple of events and driven by someone who knows how and the car still didn't get under .38's.

I would bet a twisty track would make that thing shine.

Maybe next year things will get better.

An Si FD drops in that 4 speed?

[R2 Racing]

Well yea, I'd expect to get walked down the straights with a stock, unopened engine, transmission, and computer. So would any car against a well preped one. Especially in ITC - that extra horsepower makes a huge difference.

I'm not positive if those other final drives will fit because I haven't done it myself. I do know of people who built these cars who claim they did though.

You forgot the original honda! http://Forums.ImprovedTouring.com/it/smile.gif
73-79 Civic 1200
Dont laugh I was looking for a 510 for ITC and drove mine and bought it on the spot.
1710 lbs is the ITC weight, I have to figure out how to get it there legaly though.
The 1200 is a crosflow all aluminum engine
Has a 4.93 Final drive stock, with 4.73 and 4.64 as close as the local wrecker.
Power stock is 55 hp but it gains a bit with the IT header and weber.
If you compare that to the 70 hp stock and 2000+? pounds of the 5th gen Civics, its not unreasonable. Power is down but its handling is unbelivable. Aerodynamics suck but if you look at H-Production results for the last few years I think the old civic still may be ok for ITC.
Parts are hard to find but when you do they are cheap. New Koni's for $25 each http://Forums.ImprovedTouring.com/it/smile.gif, Parts cars for 15 bucks http://Forums.ImprovedTouring.com/it/smile.gif ....

Don - where are you based out of? I want to see that thing when it's done! I love those 1st gen Civic's.

My business website is www.autoracer.net (http://www.autoracer.net) there are a few picures of the suspension on there too.

What other cars can I yank the final drive out of?

[Catch22]

I have a '91 Standard hatch that is doing very well in the southeast where we have to run against multiple ARRC winners at pretty much every race.

The handling is supreme. It has the exact same suspension and brakes as the Civic/CRX ITA cars, so go-fast goodies are plentiful. This also means it will outbrake every car in ITC if you set it up correctly.

The keys to making it fast in a straight line lie in the gearbox and in the ECU. A 4.25 FD from the Si cars is a big step (yes, it fits), but the 4.7 is even better. This doesn't come without a price though as it took us months of work and development (including over 30 dyno pulls) to get the car "right."

It finished 5th at the 2003 ARRC with the motor still "under development." So far this year we've taken a 3rd at Road Atlanta (behind 2 former ARRC winners) and officially declared the motor "developed" this past weekend in winning the sprint and enduro at VIR as well as besting the track record.

All that said, don't forget about the 92-95 Civic CX. On paper this looks like it should be an excellent ITC car and doesn't come with the difficulties of dealing with the 4 speed gearbox from the 88-91 Civic.

And old reliable is of course the 1st gen CRX. Its always been a great ITC car and still is. I just personally hate dealing with carbs.

Good Luck with your choice,

I'm running a 90 Hatchback that we built last winter. It runs well except for running out of breath down the straight. We have played with the computer and fuel pressure, but I think we are going to have to do a final drive to make up some difference. Through the corners its great (I have a tendancy to be quicker through the corners than quite a few ITB cars and Miatas).

I assume I need to find a '88-'91 Si to yank the final drive out of, or find someone to supply me a 4.7 FD for under $950?

Thanks for all the input.

Well, there's your answer Spank. I talked to Roger T. on Sunday and he suspected the same thing. If worse comes to worse I have three spare Si transmissions sitting at the house. How many do I really need?

[spnkzss]

Sounds like we need to talk Gregg. I'm not trying to run any track records so a 4.25 should surfice. That's assuming you'd be willing to come off one for less than $950 http://Forum.ImprovedTouring.com/it/wink.gif

Hit me up when you have a few minutes @ [email protected]

Then again, I've seen you drive, you just might want to save those 3 trannies for yourself ;P

[Catch22]

We started out with the 4.25 from an Si. It was MUCH better than the stock 3.8, but we decided that we wanted more spunk on corner exit and went with a 4.7.

The downside to the 4.7 in the 4 speed is that you might have to run 2 different tire sizes (depending upon the tracks in your region). With the 4.25 I ran 225/45/13 tires everywhere but with the 4.7 I have to run 225/50/13 tires on tracks with longer straights. It's workable, you just need more wheels and more garage space.

BTW - If anyone needs some 13x6 Honda/VW wheels I have a set of nice Enkeis for sale.
$200 plus shipping.

Houseman is currently building me a 4.80. He'll build just about any ratio.

[Catch22]

Yep. I figured that a 4.55 FD was the perfect gear for the 4 speed box. With the exception of places like Daytona you'd be able to run the 225/45/13 tires everywhere and have great corner exit poop.

So I called Houseman and got the $1400 quote to build a 4.55 gear and decided shortly afterwards to go with the 4.7. I couldn't bring myself to spend that kind of money on a gear for an ITC car, and I got a great price on the 4.7.

[EV]

Hey Gregg, I need an Si trans too. Catch-up with me at Summit sometime. I will be there for the nationals working EV.

I will also talk to Rob as he could use my FD from my car.

Sorry to do this here, but I don't have his email address.

Gregg,

I will be at the Tech Day tomorrow Sat. the 27th at J&L Automotive.
