wow.... it took one bad apple...

anyways, it's a 4g93 1.8L mirage manifold.

here's a little port matching to gasket.

here's what it looks like in the plenum chamber(is plenum chamber redundant?). throttle body flange has been bored to 62mm to accept a 1G dsm throttle body.

here's what it looks like with all the intake crap transferred over.

here's what the stock g94 intake manifold looks like next to the ported g93.

okay, so the manifold bolts right up to the head. i didn't port the head or anything cuz i didn't feel like taking it off the engine. what you will have to do is fabricate a plate to mount the throttle body cable to. i just bent a plate into an "L" and drilled holes in it. you'll also need 2 extra stock short throttlebody bolts. the stock intake manifold came with 2 short bolts and 2 longs ones. you're gonna have to buy 2 short ones from the dealer to bolt the stock throttle body back on. you will need to buy a 3/8" hose coupler and maybe 10" of vacuum hose to connect the manifold to the brake booster.

so far i haven't driven it anywhere because my driveway is full of cars. i'm probably going to go take it out in an hour or so cuz i'm going to get a set of nuts and bolts that bite into the metal for the throttle cable bracket. you wouldn't want it coming loose while you're driving. well the worst that could happen is that you won't be able to floor it anymore.

so the gist of it all is that it'll bolt up and fire up. you need to fab a plate for the throttle cable bracket. you need 2 short throttle body bolts.

the big why?

- it was $60 shipped.

- $60 in in porting tools($20 ebay die grinder, $20 non-ferrous carbide burr, $10+ for sanding shank and sand paper rolls)

- my own labor for porting and install

- Dave(Mitsiman) at RPW said it flows better. I wouldn't doubt much from a guy who's been tuning the both the g93 and g94 since forever

= $120 (and maybe 3 days of work) for a ported intake manifold thats better than a stock ported manifold. kinda worth it for me compared to the price of a vendor manifold.

testing will be done later today.

1G DSM throttle body should come in on monday. if anyone wants to know, i got that for $52.10 and is bored to 60mm. throttlebody flange is ported to 62mm because the dsm throttlebody flutes out to 62mm again after the butterfly.
