n/a is junk huh?
Hey guys my name is Ivan and thats the conclusion I've come. I understand that its a reliable engine and all, but I want to drift and time attack and sadly n/a won't cut it. What I've noticed is that most people will either swap for a bigger and better engine or turbo the n/a. Am I wrong?

Yes. Any engine is only as good as you build it and the car its in. A pro built Bridgeport or P Port in a light race car will dominate in the right hands.
Most people get a reliable NA built up and then switch over to boosting when they are settled and know the cars better.

This info is everywhere on this site and others. Look up "rotary porting".
Basically
stock s4 146 hp
Streetport 170-200 hp
Bridgeport 225-250 hp
peripheral port 275-300 hp

I had an N/A once and it was a fun little car. Not fast in a straight line but it handled well and the rear came out easily. I know guys who drift N/A FC's in local competitions too. Anyone who needs a turbo to drift one of these things should spend more time behind the wheel, in my opinion.

Yeah I want to drift it but it has 200k on the engine and I'm not trying to pop it. I'm currently debating if I should rebuild or swap. Speaking of popping, would porting put a lot of strain on the old engine?

Porting requires rebuilding the engine so no.
If an engine has lasted that long i think the previous owner took amazing care of it and it should keep running great so long as you treat it right with oil changes, maintenance, and maybe premix.
Also you need a new differential or just an LSD to drift properly.

New gaskets, apex seals springs - $500
Streetport and bridgport or only a 25-50 for the templates plus the cost of a dremel and bits. Also if you want hte most out of a bridgeport you need a tune, or carb setup.
PPort is serious business and should be done by a pro. That is big money.

Yup. Transmission changes come into play when you up the torque a bunch. Aaron ran his NA transmissions well over 300 hp for a while before shredding them. ANd that was with a fairly aggressive turbo setup. Im sure a Pport wouldn't really shred an NA transmission so long as you were dropping it like its hot all the time.

Street ports generally cost around $400, not sure on prices of others but I'm sure the peripheral port is well over $1000
From lowest to highest.
1. Streetport
2. Half Bridgeport
3. Full bridgeport
4. Peripheral port
As far as the transmission if you're hard on your transmission its worth it, though Turbo cars obviously benefit more since they can potentially produce alot of torque.
If you take it easy and aren't doing clutch dumps launching, etc all the timethen it should be fine.
Aaron cakes car I think had an open diff, so less strain on the transmission, an LSD with posi obviously puts more stress on the drive train.

my na is beat to **** and i love the power ! its great to learn on and in the rain more than enuf to be sideways all day and i just dont shift lol it just revs and keeps on going and i have no worrys about messing with the engine becouse it just feels bullet proof. but the diff is open so i will need to weld it or put a lsd in to really drift and keep that drift going.
i am a new driver so i only have time in slow as poop cars and craqzy fast v8 suvs so sports cars are new to me. and i learned to drive standard on it so thats hard on the drivline lol

it's documented that the 6 port bridges offer almost no actual horsepower gains unless you were to switch to 4 port irons. you will get the "brap brap" and less fuel economy but that's about it.
n/a is better to start out on, when going turbo you will want to take slower steps in making more power reliably. most people go nuts with turbo swaps and wind up with bricks.

Also you'll only get the full power out of any port if you have a header back exhaust, ported engines with stock exhausts are pointless.
As far as the porting I listed I was just using the list as a reference for pricing.
Street porting being the cheapest because it involves the least work.
A peripheral port would be too loud for the street anyways.
