There are retired SSC cars out there for cheap money. Anybody move one to ITS yet?

We ran 2, loved them. First car was a stillborn motorola cup entry with under 10k miles which got rolled. Replacement was a salvage tub we actually built as an EX for ITA then realized that was a huge waste of time and changed it back to an Si for ITS. Sold it to someone in atlanta. There's anotherrunning in florida region, and at least one in the WDCR

They can make weight. They make good power. They have awesome brakes for their weight, and of course honda love. But they aren't quite pointy end of a strong field good.

Chip,

You guys got one to ITS minimum? Wow. Based on the SSC weight, the ITS weight seemed optimistic, considering the rules. We will likely set it up for T4 (lower spec, but not too far off) go for ITS min weight and ballast/fuel her up for T4.

Anything in particular that transformed that car? Anything that wears alarmingly quick?

In SSC trim, the car is a total pig. Really hard on tires given the weight.

Kai in the WDC region runs one. Good overall all car though.

yes, and we had about 25lbs of ballast in the car. they make weight.

transform the car? most updates are cumulative, none are transformative (it's a good platform to start)

recommendations:

Get a good diff. We had a Mugen but there's options - note that the B16's box is sort of a hybrid ITR/CTR/GSR so make sure you know what fits it. we ran stock final drive.

header is always worth ponies on these cars - make sure you get something designed for the purpose. We ran a drag part and it was good but with room for improvement. intakes are pretty run of the mill, most work well.

ECU - tune the thing. lots of power available here. Honda S300 P72,moats demon P72, megasquirt, AEM, chipped P72 - all are viable.

adjustable Fuel pressure, gauge, and an upgraded pump (250 lph walbro or similar). our needed almost absurdly high fuel pressure to run right (50-60 psi at idle), and was a bit finicky about it. some of this was, undoubtedly, in the tune. at the time we were stuck with the recalibrated chip we had in it.

typical Honda ignitor failures - PM or Email me if you want my suggestions but there are a lot of ideas here. simplest answer is to use OEM components and keep them cool, though there are options, particularly with an aftermarket ECU.

internal motor work is typical IT racecar. dot the i's and cross the t's and you should be good. DO replace the oil pump whenever the motor is apart as the gear in it is known to go kablooey every now and then. harmonic dampers should help, but add inertia.

get the best spherical suspension bushings from Kingpin Machine, koni RACE shocks (EG fitment with spacers for the rear LCA mount)

also note the differences between touring and IT rules, like power steering, and don't make the conversion from class to class harder on yourself than it needs to be.

SLOWLY building one now. Making weight is not going to be an issue, even with a 200lb driver. It is amazing how much weight comes off the car (legally). I know of one other running in the SE ( I think it is one of Chip's old cars). They are beginning to get it sorted.

As stated, should be a good car, but probably not dominant at most tracks.

Even in "almost" SSC trim it showed pretty good pace. The loss of 300 lbs should really liven it up.

Just to clarify from the original post, the years in question are 99-00, not '01.

if it's yellow, it likely was ours. now on its second owner since we built it, the guy in the middle used it for track days and I don't know what all he did to it other than move the seat and change the number. good, fun cars.

Completely concur with Chip's suggestions. This is really a lower-powered Integra, so anything/everything that applies to the Integra applies to the Civic.

IMO, this car will do well if wheeled hard, but it's a long row to hoe in the higher-powered world of ITS. Kinda like the CRX Si in ITA. I think will do good on shorter handling tracks, but get its lunched eaten at long fast tracks. - GA

Thanks a lot guys, especially you, Chip.

We are going to start the diet for this pig and see how fast the weight falls off.

Greg, I know you are correct. The pointy end of ITS here in the northeast/midatlantic has some pretty darn fast cars. The bimmers in particular have a lot of grunt.

A Steve Eckerich diff would be great as well.
