beams redtop question Options

[Antz5SFE]

i have searched & i know these parts are hard to find but what do you guys think is my best bet for finding an oem downpipe & airbox? i saw a few 3rd gen 3sge downpipes on ebay maybe 2 weeks ago but they arent there anymore & i dont know if they are interchangeable with the 4th gen since the o2 is in a different spot.

[richee3]

The 3rd and 4th gen down pipes are interchangable, but you said it best- different O2 locations. An exhaust shop could fix that. For the intake, you can buy the intake lid from Vincent_Doggy and use the bottom half of the 5S intake box.

thanks richee. i found the wiring diagrams for the redtop beams on the mr2 forums but i think the link is broken they wont show anymore. if someone could post a link to the wiring diagram or pm me it that would help a lot!

[richee3]

It's in my progress thread, ricochet1490's thread, njccmd's thread, and a couple others. Better than wiring diagrams, it tells exactly which wires get repinned.

hmm im not so sure on this visually they look the same as i myself stated that.

sometimes nengun auctions has an japane exhaust and they say it will fit an beams engine. then when you look on the exhaust system there is a 3-4 inch long extension.

the 3rd and 4th gen share the same engine block and exhaust header and b-pipe are the same visually, except a 3rd 3sge header wont bolt onto a 4th gen 3sge beams block because the flange is different. so what gives??!!

[Antz5SFE]

so bonzai you're saying that i may not be able to use a 3rd gen downpipe even if i change the o2 spot?

it seems your not understanding. you need to see that pic of the beams aftermaket exhaust vs non beams aftermarket exhaust

Check eBay they pop there once in a while, I have an hks adapter for maf you can have for 80 bucks shipped

[BonzaiCelica]

to be honest i'm quite confused as this point. this is true info:

both 3rd and 4th gen 3sge motors have the same length b-pipe, same catylitic converter and have 57mm exhausts.

on this page you can see that little section i speak of its called an adapter.

and page 6 of the same thread of it bolts up to the car.

this little thing



came with my exhaust, it literally is placed between the exhaust and the catalytic converter.

i searched several places for a TEST pipe or decat pipe, since i was not going to pay 200 for a cat.

long story short the exhaust guy gave me the idea to extend. and u can do that with any set of flanges and pipe, nothing special...

that exhaust was meant to be installed in a 3sge engine, so your situation might me different. you may just want to build an e3xhaust from scratch

[BonzaiCelica]

thats what im saying norberto. The exhaust system is the same for 3rd gen 3sge and 4th gen beams up too the catalytic converter then why is that adapter placed there is makes no sense.

anyways he's after the b-pipe. yes go ahead bro get a 3rd gen 3sge b-pipe they have the same part number exact the last digit. which is the relocation of the oxygen sensor

[Antz5SFE]

my beams did come with a trans(non-lsd) but we are going to use mine because everything is brand new. i see most guys switch over to the 3s flywheel & pressure plate, do i need to do this?

[richee3]

Yes.

Edit: Now that I'm not pressed for time, I'll elaborate. The BEAMS has a unique flywheel, not shared with any other engine. At 14-15 lbs, it's lighter than any of the other 3S flywheels and if I'm not mistaken, the 5S flywheel will not fit. In addition to being lighter, the design of the flywheel puts most of the weight closer to the center, helping it act even lighter. Because you will be using the BEAMS flywheel (or lightweight 3S-GTE flywheel,) the 5S pressure plate will not bolt up. I'm using an OEM pressure plate from an ST185, OEM BEAMS clutch disc (same as the '99 Celica GT,) and S54 throw out bearing.

Pic of the BEAMS flywheel compared to a pic of Dustin's lightweight 3S-GTE flywheel. Notice the surface area of the BEAMS flywheel is smaller but closer to center.

how do you guys go about diagnosing the beams?

[richee3]

Like check engine lights? It's in the diagnostic box, use a paperclip or short piece of wire to ground the TC1 pin with the key on then count the CEL flashes.

What's my options for the maf & intake...i saw a few guys rig up the right tubing with a cone filter..i know the beams is very picky when it comes to the intake. I'm really just looking for a cheaper route than buying the top of the oem intake box for $175.

[richee3]

You can buy a SARD intake for $200, which is the only aftermarket intake for a BEAMS. You can also pick up njccmd's HKS intake, or go cheap (by far the cheapest option) and pick up a 97-01 Camry intake from eBay. The MAF is the same as a '97 Avalon, part number 22204-20010. As picky as the MAF is on a BEAMS, you'll definitely want the OEM MAF as opposed to an aftermarket replacement. You can get away with the aftermarket intakes but my butt dyno felt a decent difference between my Camry SRI and the stock intake. To me, it was worth the money for the stock intake, but it seems like most BEAMS owners keep an aftermarket intake.

thanks richee you've really helped a lot. i have the maf part # down as 22204-20010. i'll probably get the oem intake then. one more question for now, about the b pipe. i found a 3rd gen 3sge b pipe, i understand the o2 is in a different location & saw a picture of both. do i have to get another bung hole welded in or can i extend the o2 somehow? have you seen anyone run a 3rd gen b pipe on a 4th gen beams?

I've never seen it done, but a good exhaust shop could probably move the bung for you. If not, it wouldn't be hard to extend the O2 harness, it's only 4 wires. The O2 does very very little on a BEAMS. It doesn't trim fuel, it only reports rich or lean conditions via the CEL. I can't see any issues with moving it to the 3rd gen location, since its still before the cat.

[njccmd2002]

actually i did have problems with that 02 sensor. I failed to plug it on my first few drives and the car ran like crap. would not idle, and turn off. i ran like an old beater, until i went back and checked all my connections, was that i found out what it was, then i just pulled the ecu fuse, and had the ecu learn again, and it made a difference.

just try to put it in the same location, you cant run without it, but slightly moved, wont make a diff.
