would like info on my FC build

[Turbo vw]

Well this will be my first rotary build, my car is a 88 FC s4 GXL I believe its N/A completely stock was a DD for my buddy and it just shut off on him one day don’t really have any idea what happened or why it happened. Ok iv been talking to a few of my buddies that are on this sight and on another local forum and hears what I have come up with for my billed

Ether use a complete s5 motor,
Or s5 rotors in my s4 case
Street port
up graded springs
Rx8 E-shaft
Header
Full exhaust along with no cats
Custom set up cold air intake
Clutch
Flywheel

I’m open to any advice that any one would like to give me. Don’t want to spend a hole whole lot on the billed. But I want to have a decent car I can go out and play in. Also don’t want to throw a lot of $$$ in because this is my first rotary billed so I don’t want to mess up and have to much in the car


also would be interested in some other info to

Some sort of big brake kit (prefer something I can make using used parts from other cars)
Upgraded springs probably eibocks
Or a set of full coilover’s
Camber caster kit
Strut braces
Sway bar’s upgrade
TII Trans, drive shaft, reared and axles


And if any one has any of these parts around and would like to git rid of them id possible be interested prefer motor parts for now but would considered outers

Sounds like a nice start. If you plan to rev it like it should be revved add and FD oil pressure regulator.

o yea and in the rebild kist im looking at im planing on up grading the springs to with the bild

Keep the S4 keg, upgrade to S5 rotors. I dont see a real reason to use an RX-8 shaft unless you like spending money on something that could be chewed up (seen the insides of a blown renesis and old bearings....its not pretty).

Streetporting is a good idea, choose your apex seals wisely, oem is usually the best.

What header are you going to be using? Any NA with no cats is going to be loud, a header is louder, and no presilencer (like found at racingbeat) is going to be illegally loud and draw lots of attention from johnny law.

Though have you confirmed if this car is really blown? "Just shot off" is not really consistant with a blown motor. Blowing a motor feels like you just got half your power stolen from you and the engine shakes like a beast. Ive DD'd my own FC for a week on 1 rotor, started and ran every day on that one rotor until it was removed and replaced. Sounds more like a spark or fuel issue to me, though confirm its blown by pulling the plugs and just listening to the sounds coming from them. Wooshes indicate 'healthy' seals, while nothing at all means blown.

Good luck and hope my post helped.

i know the preves 2 oners of the car and both complaned of under power the stock motor has 126K on it id say it ant really blow up didnt smoke any except for the useal cold start. i just figer it would be best to go ahead and rebild it and im perty shure the clutch is gone the guy that had it last sed it was and i know this is the car he lernd how to drive a stick on so so you know how that gose

why would you keep the s4 case? insted of giting a complet s5

and from what i was told is the Rx8 E-shaft was a lighter shaft and had better oiling

as for my sils im planing on just the classic kit nothing big with up graded springs

im just going on what i have been toled not trying to question ur resons just trying to lern

Yeah, a actual blown rotor or one running on just one rotor for some reason will sound like flat-4 engine.

lol im cheep to lol but i dont mined spending a we bit extra to git a little bit more power

[TehMonkay]

S4 Shortblock
S5 NA rotors
Race rotor bearings, 3 window bearings in stationary gears
FD front oil pressure regulator spring, rear FD oil pressure regulator
Streetport
S5 NA Intake manifold
6 port sleeves removed
VDI wire open
RB Header to exhaust of your choice
RTEK or some other sort of tuning tool
No need for an RX-8 E-Shaft in a mostly stock build
aluminum flywheel
act street clutch

If you're staying NA i'd rather go with an atkins type B rebuild kit instead of the RA, but it's your choice, definately get the upgrade seal springs though.

Make sure you clean everything properly
Change all coolant hoses, flush your oil cooler and radiator(professionally), change your waterpump and thermostat(OEM thermostat only, no aftermarket POS, buy it from the dealer!!!! or you will kill your engine) while it's still easy to do, buy new stainless oil cooler lines if the old lines look worn.

Also look into cleaning your injectors and changing the wiring connectors for them as well.

After that look into a Racing beat suspension package, poly bushings and koni sport/yellow shocks, with camber/caster plates and a rear camer adjustment bar.

You dont need a big brake kit, get these:

Brembo blank replacement rotors
EBC Green Stuff Pads
corksport Stainless steel brake lines
New Master cylinder
ATE super blue brake fluid (or anything else DOT 4)

That should refresh your brake system a whole lot and let you stop safely on the street. The stock brakes are more than adequate for any turbo car, much more so any N/A car.
