3S-GE BEAMS swap

[hmong337]

Any comparisons on the power delivery of this engine compared to the FA20?

[FReSh]

This brings me back to the days of messing with my red-topped '91 MR2... That Glen character that Manji mentioned is quite the source of knowledge with these motors and has (last I read) a pretty nice set-up in his Celica. I know he used to post a bit on the mr2.com forums, but it's been a long while since I've been on there.

I'd like to see an FRS with a blacktop. I'm pretty interested in the weight difference. IIRC when I had the redtop pulled from the MR2 it seemed pretty heavy for a 4cyl engine. Classic Toyota (Yamaha?) iron, I guess.

Also, check this out: www.beams-redtop.com

Yup, I'm with ATS (I'm one of the two that boosted Aaron's car...which is now mine). He's known for awhile you are doing a beams swap, so you must have told him back then.

The 3s ge is an awesome engine. You can hammer it for years as I did mine in my previous car and it just keeps on ticking. Also makes similar power to the fa20 but is no where near as fuel efficient.

Maybe the next gen fa20 will be as reliable and make much more power. Just as how the blacktop is a much better engine than the red top.

As it is I wouldn't do a swap now.

Not really, I started the swap at the end of the drivable season for our area and the car has spent most of the time parked, currently finishing up the turbo setup and will have it at TX2K - just as transportation unless I run into some huge snag.

This is a blacktop swap just in case that wasn't clear. I don't have the exact differences in weight, but couple things to balance out, you have two aluminum heads on the FA20 and only one on the 3sge, I just packaged up a full set of FA20 heads yesterday and they weighed 88lbs boxed. I feel like the 3sge head will be slightly lighter than that. I am throwing out numbers but would guess 50lbs or less on the 3sge fully loaded head. So saving of 30lbs to give to the over weight cast iron block. I don't have full weight of an FA20 block but have the bare block numbers somewhere in the office and have other 4cyl cast iron blocks to get a rough idea of weight and will report back next week. Now the 3sge will definitely have the weight higher distributed.

I think a lot of that has to do with proper tuning. I will wager we will get similar gas mileage with proper EMS and tuning.

[Dustin@Dynosty]

Just figured I would post up a quick picture of the finalized setup. Made 323whp at 8psi revving to 7600rpm before driving it 16hrs to TX2K. When I find some time upon returning, will turn the wick up a little and see what it makes at 8000+RPM.

[hmong337]

This is how Toyota should've built this car!

That's awesome powet for only 8psi. That's better than every stock internal FA20 bolt-on turbo setup I've seen.

Cheers. Will be checking on your progress.

[Manji]

Nice work. It'll keep making power to 8000rpm (that's where mine makes peak power) but it'll fall away in a hurry after 8200.

This is what happened to mine a week ago..

Too many drift runs in 4th gear, sitting on limiter


I'm flattered you copied my plenum

Dont know if it's because I never grew up with the MR2 but i dont see the point at all in swapping this engine. Maybe this swap would be worth it in a car that has a poor engine like a ae86 but I just cant see the point in a twin. It's a old engine, heaver, and just the cost of the swap + a turbo just dosent make sense to me. For anyone who is going to comment on my post saying "twins cant hold power" im going to link you this post http://www.ft86club.com/forums/showp...87&postcount=9 All those threads you have read from engines blowing are from poor installation or a bad tune.

[Manji]

Can't tell if trolling or just stupid

[Teseo]

I dont like the boxer anyomore, i'd like to see those engines with a itb. Its possible to achieve 200+ hp @ 10k rpm?

Thank you for your comments, but this is the swap forum, if you do not want to contribute to it with any thing other than confrontational comments you can please exit this thread. It is comments like these all over the board from people who just want to start a pissing match on the forums that create such a negative environment that no one wants to post any useful information any more and why intelligent vendors shy away from posting anything at all. IF you decide to combat again, I will report you to the moderator of this section.

Report me for what? Making a related post to the thread? I simply stated my thought on the engine and was hoping someone would chime in on something I missed that would make this swap worth it, I just simply wanted to know, also when I first read the whole topic @Manji post never showed up for me until I went on my phone this morning, if I had saw that then I could see why. Sorry you got so butthurt over a post over your love of an old engine.

Seriously, what's your point? I can go on about how shitty your rims fit but I choose not to. You are a troll. Please exit this thread.
