I have all the welding and fab skiills needed for any of this...and this is a heck of an idea.
Keep the stock header and 4-2 and 2-1 collector of the stock beams b-pipe, and then put your turbo and turbo flange etc etc under the car. protect it with an underbelly pan like vincent doggy and culpable sell, or make your own..

or put it afte the 4-2 collector and have in the front but down and out of the way towards the front before subframe gets in the way....

Syaoran, nice idea...

But also good idea about taking a gen two manifold and adapting the beams mounting plate... I've got all the welders needed for that.... I just ate how it looks.
Afte the collector feels like it would be a "cleaner" look.

Very interested to see how this turns out.

what do the pros think?

better yet....
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewI...atchlink:top:en

you need atleast a t28 spec turbo for a 2L, that little t25 size turbo will choke at high rpm where the engine would normally flow more air than the turbo can provide, what you will see is 12psi at 2000rpm and slowly go back 11,10,9,8...0psi by 6000rpm

a regular t28bb non-rs would be best bet for a turbo beams, the one on the jdm s15 spec-r or in garretts catalogue "gt2560r"

you really need turbo (low) compression for the gt28rs (gt2860rs) as these things are happy to spool up 22psi faster than your foot can sink to the floor, and thats not the kind of boost you want to be running on a high compression beams motor, so you may aswell save yourself some lag by getting a turbo thats more efficient at lower pressures like 7-10psi which is precisely how the jdm sr20det turbo operates.

that plain "t25" size turbo is more suited to a 1.6-1.8L engine running 7psi, to boost peak hp around 200hp which is already what your beams motor makes so provides Nothing at all.
the idea of this turbo is to give you the power and torque of a high performance 2 litre NA in a small lightweight 1.6 package.

when I chose the turbo for my engine i did alot of research comparing compressor maps, dyno plots. i knew exactly what my goals were in terms of peak power potential, how early torque became available, i had to fit within the limits of factory tuning, i had to have a turbo that spooled early to give me torque outside of (before) the natural 3sgte engine torque band (4000-6000) and also not die off after (6000-7000), and also fit in with my no lag factory w2a setup but not outflow it, etc and while i'm happy to rave about what a great turbo the gt2860rs is, its not the right choice for every 3s setup

Delusionz - I wish we had a "thank" button. that helps provide me with a better range to look in. I'm trying to figure out what it all means all at once and it can sometimes be a little over bearing.... steep learning curve

http://www.turbobygarrett.com/turbobygarrett/turbocharger


What you'd be looking for is a small turbo that has a higher flow rate at a 1.5 pressure ratio up to 2x.

2x pressure ratio means twice atmospheric, so in other words if atmo(0boost) is 1bar/14.7psi then 2x pressure ratio would be 1bar boost, 3x would be 2bar boost etc...

if you work out how much air your engine will ingest on its own at the redline, you need to be well above that with the turbo in order to keep making boost

btw i had another look


wouldnt let me put this one as an image
http://www.turbobygarrett.com/turbobygarre...1&4comp.jpg



seems the GT28RS is better than the T28R at low boost AND high boost (my bad)

Here's an item you could look into:

http://www.ebay.com/itm/MR2-Celica-T25-T28...9d5&vxp=mtr


You could cut the 3s-gte flange off and weld on your BEAMS flange to it, and you'd have a nice manifold ready for a t25 flanged turbo.

I did the same thing have the same manifold, ordered 3rd gen flange from the UK and welded it on...

I would take a read at this mans testimonial...And some others as well.

Turbo Redtop

Supercharged Redtop (long read)


Personally i dont have any advice to offer on my own. Although i am still in the works with my redtop build, its far different from yours and the best advice that can be given, was already typed.

But i would definitely read the links above. Alot of people have traveled down this road from what it seems.

links already posted on page 1. read them both. But thanks for re-iterating the importance!!

And not a lot of people have been down this road from what I can tell... its charted only by those who have $$, no girl friends or wives, and the time and energy to devote to making something fully custom...
Luxerys most of us don't have including myself

Lol no problem, im here to make sure the point gets across....Umm to others, hahahaha....but it sounds like you have much to work past in this endeavor....Good luck and ill just sit back and continue to monitor this thread....

http://www.mr2.com/forums/beams-parts-swap...et-up-sale.html

holy shat..... i'm speecheless

that would be nice!! for $3,600 plus an aem stand alone $1,200 with another $500 in tuning. That setup is capable of another 100whp to the beams motor. $5,000 for another 100-150whp not bad, plus unique factor

after so much money he quit?

he spent years developing that, he barely finished couple months ago, gives you the idea of how much power he did not make, because he wants more..

sorry guys, just look behind the curtains.

the beams is an awesome n/a engine as is, but if you want more power from it, better forget it. as it will cost you, and in the end you wont be satisfied.

thats his story... its sad, but true

He's not quitting. He's going bigger.

I think hes going to sell it... but then again maybe not..

wish him luck.

that is not worth it to me. i wouldnt spend anywhere near that much money for 100 HP

Seems like a lot of work to end up with a 3sgte with vvti.
That might not even make as good of power as a 3sgte swap

GEEZ ALL YOU DEBBIE DOWNERS, we know you can spend that money on a 3sgte a get twice as much hp. price is not what we are after.

i dont know what everyone fascination with the BEAMS is. its still an iron block engine that only makes 200HP to the crank. the power to weight ratio is just not there.

They could have made it out of aluminum.... you and I both know that. But from a cost standpoint i'm sure toyota said hey... we want the same block and we could make it out of aluminum, but that would mean re-making the dies etc etc.

I think of it as a more baller 1/2zz that doesn't burn oil, has better power and torque, and is a direct bolt it that has a really nicely flowing head that looks nice in the engine bay, and looks good with the red valvecover/intake manifold LOL

just a motor smaay.... frankly I"m not impressed with 3.0L+ v6 only making 200 flywheel hp

The v6 is more about the two lol
It feels a lot faster than it should be lol

yea they could of made it aluminum. Also to my surprise the 1990+ Acura NSX already made aluminum engines. I thought it was only late 90's technology.

btw smaay finish your swap already. that way we can have a meet in so cal and would like to see that v6 power!
