FC vs FD?

OK, well here's my predicament. Ive wanted an FD for as long as, well since i got my FC. But current financial situations arent that good, and i cant really afford one. Damn it. Anywhoo, I was probably just gonna buy an 89-91 T2. Now my question is, what would it take to make that as fast( maybe slightly faster ) as a stock FD. What is the top speed of the 89-91 T2's?? I know after like 110 on my gxl a snail could probably accelerate faster, its kinds depressing. Could a slightly moded T2 keep up with an FD on top end?? I love FC's almost as much as FD's, not quite, but they are still sweet, I am just in the need for more speed. I could afford a T2 fc, and there are a few for sale around me, so it wont be a problem getting one. I just wanted anyones opinion on making one run mid-low 13's, RELIABLY!! I know its possibe easily, but I wanted to know what needs to be done exactly and how much it would cost. Thanks for the info, and sorry for the long post.

you can easily make a 2nd gen as fast as a stock FD. and it will be more reliably then a stock FD, and alot less also much easier to work on.

I would think intake, dp, mp, catback, ported wastegate, boost controller set to 10-11 psi and maybe some 720's up high run by a G-Force ECU or Apex-i S-afc should get you where you want to be. A lighter flywheel wouldn't hurt either.

I've only run against one FD and it didn't appear to have anything more than catback although it was making a really brappy sound so I suspect a midpipe as well and we ran from about 60-110.

He was about 3 cars ahead when we went and I was starting to inch him up high in 4th before we had to shut down for a light. (he might have had a passenger - tinted glass at night)

the T2's can certainly be made as fast as the FD's in most cases. getting one is the harder part. i was searching for OVER A YEAR before i found my 1991 TurboII. i would search forum for sales, thepartstrader, autotrader, classifieds2000, yahooclassifieds, local stuff......and could hardly find ANYTHING! either they were beat up, or people were asking too much. so all in all a nice 89-91 T2 is A LOT harder to come by than a decent FD. they usually pop up in cali but elsewhere they are scarce.

i'm sure there's a few people on here with just intake and exhaust and a FCD that run low 14's. with an upgraded fuel system and some more boost, you can run 13's on a T2.

I am not sure i witnessed the speed of my friends TII and he said he could damn near pace third gens with his very few mods. all he had was an Iceman intake, Full 3 " exhaust and removed air pump, power steering, and ac. Thats what he said and he and i kinda messed around when his friend was driving and when i shifted in to 3 he had like 3 or 3 1/2 car lengths on me. I have a stock 87base with a system, and no exhaust but man that thing flew. not sure what the previous owner did to the motor but he autocrossed sevens.

According to Chris, Ari and Rocky at Rotary performance a T2 can be just as fast as any FD stock or modded. Chris actually said the T2 would be more reliable than they FD. But Rocky and Ari said you wont get laid as much in an T2 as you would an FD. So theres is your real delimia. How much do you want to get laid???

Im 32 so Im slowing down in the laid department.... not really just had to say that for my age..... But Im cheap so Im probably gonna go the T2 route, but I need another truck first (V10 in a Dakota???) I can get laid at any country bar cause I know how to dance and leave the girls heads spining when Im done (ok cowgirls really like to be spun around hint hint (and thier tight little a$$es in rockies.....sigh)). But how much do you want to get laid???? Guys do everything to get laid that is why we are alive to get laid everything else it just icing on the cake to attract the women to us.

HMMMMMM maybe i should go to the louge and start a tread on this thought????? Look there for a follow up thread on this line of thinking.

Here's my experience with an all original '87 TII that had 143k miles. Everything worked and it seemed to run perfectly. Probably not as well as a lower mile engine would run. I think a good driver might be a half second quicker than me at each stage of the below modifications, especially with better tires.


Mods for 09-10-99

Fuel Cut Defenser
GReddy Power Extreme 60/80 mm Cat back system
Bönez main converter
Bönez Air Intake
Firestone SH30 205/55 street radials on factory 16" TII wheels.
Modifications running cost total $1,563.00 (Does not include tires)

1/4 Mile data

Lots of tire spin.

09/10/99
14.76
98.21


New mods for 10-30-99

2 1/2" Bönez downpipe
720 cc Secondary Injectors
Apexi Super AFC
Autometer Air:Fuel Ratio Monitor
Autometer Boost gauge
A-Pillar Dual Gauge Mount
Modifications running cost total $2,343.00

1/4 Mile data

The car is not much louder than a stock Turbo II and gets
better gas mileage. Lots of tire spin.

10/30/99
14.51
99.84


New mods for 11-07-99

GReddy Profec B-Spec Boost Controller

I think you're clearly expressing your wishes for a "Sex and My RX-7" area to be set up on the form.

Get your hands on a 89-91 stock, running, TT FC and you are set. This was the problem I had so I opted for a 89 GTUs N/A. No turbo or anything and I still think it is fine (just a little smoke ). Anyway Take the TT and put a new exaust; preferably high flow, along with a new intake and get the Turbos as sequential as possible. Maybe 800 dollars tops. I know this because my friend runs a set up simmilar to this and can kick an older guy in town who just got a stock 94 FD. So happy hunting because it took me three months to find my car however, it took three years for my friend could nab a TT.

FC = Yeah!!!
FD = Boo!!!!

I don't know why, I just don't like the FD nearly as much as the FC.

The cars will mod very similarly. The FDs have tons of kits available, you will have to fabricate some stuff if you go with an FC.

The one leg up that the FD has (in my book) is in the handling department. They handle like they are on rails... an FC can do the same, but be prepared to drop coin on suspension. I'm not sure if a fully suspension modded FC could hang with a fully suspension modded FD... anyone know about this?

88 TII Mild ported engine =$1,200
3" exhaust $ 270 (no cats)
HKS Filter $150
NO OTHER MODS WHATS SO EVER!--Not even a FCD
@10 PSI
on plain street tires
I run 13.5 .....2.1 60 FT

I can keep up or beat stock to low moded 3rd gen's
I've done it several times at the track
and on the street.

It dont take much to beat a 3rd gen
what makes the 3rd gen powerful
is the size of the stock ports
once you port a 2nd gen engine
you close that advantage.

As far as rwhp goes for you to compare to a stock FD. An average FD puts about 215 rwhp and 205 ft/lbs of torque to the rear wheels. My friend has a 89 TII with a fresh engine but 150K turbo that seems to spin nicely. His mods are, bonez intake, full cat back, underdrive pulley, and Redom ECU from Japan. At roughly 10.5 to 11 psi, he made 231 rwhp and 245 ft/lbs of torque to the rear wheels.

Correct me if I'm wrong, but aren't you inadvertantly saying that, a stock FD would only have 3.5 car lengths on your stock SE at the start of your third? Come on Cooper, you know I had you buy more than that!

so the moral of my post was ... if you wanna have a fast *** car and really dont want that many looks get an FC, if you want a nice *** car and be lil fast (some legalness to it, if you goto the street races you'll be stuck with stock Twins or you ll get impounded) get an FD
