Cost-Most have found the swap is a bit (if at all with prices these days) more pricy up front but cheaper in the long run.
Bling-Swap....samco hoses, cool IC's, inlet pipes, elbow pipes, sti intake manifold if sti swap.

RS-T's have their merit in that they can be cheap, and they were awesome before swaps became big. But swaps just make sense. It's the motor the gc8 was SUPPOSED to have anyway Yes i'm biased though
You're partially right but:

1.- Anyone with an RS-T that blows the engine doesn't know what he's doing in terms of parts and in terms of tuning. Boosting a N/A car with reliability takes a lot of research, knowledge and experience. I've been boosted for 3 years @ 10-12 psis (daily driver) and my engine is in PERFECT state; about 3 months ago I did a compression test on all four cylinders and guess what? FACTORY READINGS...
2.-As far as reliability, read point no.1 again.
3.-Power.... STI ball park. My average 1/4 mile is 13 flat. My best 12.52 @ 109mph. It takes some serious $$$ to have a 13.00 1/4 mile WRX engine running reliable.
4.-In terms of cost it's a 50/50 issue; depends a good of a shopper you are.
5.-Bling, bling no contest.... but you can always get a few goodies.

AFI all the way....

ps.-You can always build the engine into a MONSTER once all your car related debts are paid in like in my case...... it's time for pistons, springs, valves, retainers, block work, cams.......

Well, also i don't know if i would call just doing a block a swap. yes you are swaping them out, but your still working on the principal of the stock RS ECU and tuning issues. where if you had an STi you wouldn't have to worry about it.

I was thinking swap, and am still alittle. but for what i want to do, STi block so i can crank the boost, and a 6 spd for when i blow the tranny, i might as well just keep my shtuff and go AFI. granted all the shtuff is still in the basement or online needing to be ordered, but wer're getting there! I guess it's all about your plans, and how many cars you have. 2!!! in my case

You're the exception not the rule Congrats, glad to see it works and works well for some.

As for #1 yes, you are right, when i turboed my car i had 0 idea of what i was doing, which is why i like the swap more, it's alot more idiot proof.

Nowadays though with the sti shortblock it seems cheaper to do that and build a turbo kit than to do a swap. It's a great piece by piece solution.

Nonetheless i will still be an ej20 and swap fan, and from the looks of it you will be an AFI fan. That's cool, enjoy your car

Well I do not know wher I fit. I have a '98RS which later intalled a Ludespeed Turbo then sold the kit sold the tranny and sold the DOHC 2.5L. Now we are building a Crawford Performance 2.333L (aka R1) with STI v8 heads and intake manifold with an STI v7 RA spec C 6sp Tranny, R180 Rear Diff (3.90), STI v7 Front and Rear Brembos, USDM STI BBS with Bridgestones 070 and a GP Moto GT32 turbo kit.
Well I guess the GC8 body is just irresistible (specially when it is paid for.

Well my budget had a lot to do with it plus closed deck block. Originally we wanted to do the 2.2 block and the 83mm Monster crank (2452mm)but again for budget reasons we decided to stick to something different that could help keep the v8 heads filled and could do some justice to their rev limmiting capabilities (8300RPM).
Then again the GT32 should help managing a very wide RPM power band.

Thanks,

It all depends on a few factors really in my opinion. If I lived in a smog state, then a swap would be more ideal and less headaches. But since I don't, I like the idea of exploring the FI custom and learning as I go. I guess I get a little more intimate with my car .

Every custom AFI is different. I just don't like to go in there and freaking hack my stock harness. Too troublesome for me. I'd rather just get complete fuel management system and have the freedom to tune however the hell i want.

That's just some of my opinions..

Problem with Swaps usually comes in the harness- if you have the patience or enough money to pay someone with experience doing the harness, it's better. Otherwise, bolt-on is much more accessible - needs more tuning yes, but at the same, it's harder to screw up the install compared to a swap. I'm still torn...

what's crazy is that in a swap, you can expect a given power to come out, with AFI, tuning is essential to get it out and dynoing can get expensive.

So if you can spen $7k on a full swap and know you're going to get 300hp reliably vs. spending $5k on a turbo kit and another $2grand installing/dynoing, then who knows... I guess it's more of what's accessible
