Default New here (sorta), plans for my vehicles

I am gonna concentrate on my half of the car list of my sigs (its a concatenation of mine and my gf's (VideoNasty)).

my portion of the list:
1979 Porsche 924 w/M471 Option (only 500 924s in 1979 had it, it was for SCCA D-prod homologation)
the engine has already had most of the work done (my friend previously owned it. but instead of typing out all the mods.. i am gonna post a link instead: http://www.p-caronline.com/directory/shadowboy/
other info about the car:
the M471 option includes a 23mm front sway, 14mm rear sway, 23.5mm torsion bars, its very similar to the 944 suspension in the lighter 924 chassis. the A/C has been removed in this car, and the transaxle is not original. the transaxle in this 924 has the gear shafts in front of the differential (generally they are behind) for weight distribution. it also has a dog-leg 5 speed gearbox (first gear is down and left with 2-3-4-5 making up the H-pattern).
this will be a fun autocross car in a couple years.

CRX & Integra

the CRX & Integra are one project.

the CRX will be a not-so-comfortable street car, but will be a street mod 2 car, with the integra as the major parts donor.

the integra will donate its engine (D16A1, 1.6L DOHC 16V MPFI).
the planned mods include: higher comp forged pistons, port & polished head, cam grind (still researching who to go with/which grind), custom fabricated CAI, DC headers, among many others that i am still looking into
my horsepower target is 160 at the crank

i know many of you may be wondering: why not go with a B16A. 2 related reasons why: weight and its affect on handling. the car is an autocross car so i am looking for balance. the D16A1 is a bit heavier than the B16A, so i need the lighter weight up front to help reduce understeer. also b/c of this 160HP in a D16A1 is worth more than 160HP in a B16A (except for the added breadth of torque curve you get in the B16A, but the D16A1 has fewer revs so 160HP means more peak torque than the B16A, of course at the expense of smoothness).

chassis: lightened to the max.. whatever it takes, interior stripped of headliner, sound deadener, and anything not required for use of driving.

suspension: OPM torsion bars up front, coil-overs in the rear. as far as shocks go, due to cost-effectiveness, i may as well use the tokico illuminas that are presently in the integra. i will also need an adjustable panhard bar. i plan on using the integra sway bars as well, or at least the rear integra sway bar. or possibly a suspension techniques kit. i havent worked out the detail on this, balance is important. for those who don't know: the integra has a 19mm front sway bar and 17mm rear sway.

Brakes: integra disc brakes at all 4 corners. i will be either using EBC greenstuff pads, or porterfield R4S pads. or, possibly, a fastbrakes.com 11" disc upgrade, but this would require 15" wheels. the advantage of the integra brakes is that it would allow me to run 13" wheels to reduce unsprung weight and rotational mass at each wheel (i am thinking Volk TE-37s for the wheels, or SSR type Cs, both expensive but not many lighter wheels, both are around 9.2 lbs for a 15x7. thing is the SSR doesnt come in 13" whereas the volk does).
optionally i may compromise between the 2 options by going with a later 10.2" integra or civic brake size.. of course this will require some custom fabrication to relocate the caliper.

my target weight for the CRX is no more than the factory curb weight, but after all the additional stuff (in other words, i wanna at least break even with weight.. in terms of reduction vs addition).

in setting my goals i was trying to set reasonable goals that are not unrealistic, but result in good performance.

i decided to use the 84-87 CRX HF as my base over a year ago, long before i moved to FL. the CRX that i found should make a good base car. much of the plastic body work is broken, and it has a few problems (mostly with the engine & cooling, which is gonna be swapped out ANYWAY). but the chassis is solid. the rocker panels are solid.. the wheel wells are solid. there is about 1 sq. inch of surface rust on the A-pillar (that i can tell for now). i had a carfax check run on the car and its ENTIRE life since it was purchased with 2mi on the odometer was based in or near lakeland (lakeland, winter haven, or bartow). far enough from the coast to be free of the salty ocean air.

Why does your Integra have a D series in it?

the 86-89 integras had a D-series 1.6L engine

all of them coded D16A1, with a DOHC, 16V 1.6L sequential MPFI engine.

they are similar to the ZC engines of japan
the 86-87 integra had 99ft-lbs@5500rpm and 113HP@6250rpm (akin to brown-top ZC)
and the 88-89 integra had 103ft-lbs@5500rpm and 118HP@6500rpm (akin to black-top ZC)

the engine is a direct bolt-in for my 87 CRX (not without work as it will involve a carb->EFI conversion)

3rd gen is also heavier than the 1st gen integra, the heaviest 1st gen integra has a curb weight similar to the lightest 3rd gen

the 1st gen integras ranged from 2200-2500 lbs curb weight

(the 3 door RS is about 2250, and the 5 door LS is a hair under 2500)

i have a 3 door LS, the curb weight of that is about 2355

magazines have tested the 86 5 door RS integra (second heaviest) at 0-60 in 9.6s with a 1/4 mile time of 16.5s@80mph

not bad at all.

stock 0-60 times have been as quick as 8.8s

i have personally done a street start in my integra, from idling in first gear, to 60mph, shifting at redline (not rev limit), in 9.6s (fwiw, shifting at redline means a 2-3 shift, as 2nd gear redlines just shy of 60mph). i have a sound clip of it too.

not that i care about straight line performance.. the 86 5 door RS i mentioned got 0.86g on the skidpad.

the g1 integra was also compared by road & track in a subjective 4-car round-up in 1986. it actually won. (the other cars were a celica GT-S, a scirocco 16V, and a turbo DSM, not an eclipse, and not a mirage, it was FWD so it wasnt a starion, i forget the model offhand but it is one that never even saw the 90s in this country)

Our old beater family wagon was an 86 integra.

It was the best $1,200 I ever spent on a used vehicle.

Once we got the Jetta I wrote for sale for $700 on it with white shoe polish (I should have asked for more, but it was in really rough shape by the time we got rid of it) and it sold in just one day.
