the trouble for me has been finding either an after market ecu or a god piggy back and someone to tune the dang thing. The closest I've come is 4 hours from my house and they don't even do toyota..... they're all about audi, porche, VW, etc.... #frustrated

There's a shop in Toledo that does toyotas
There called accelerated performance

[Syaoran]

Tuning a car isn't that hard, ESPECIALLY when using a piggy back... start from a very safe point (a lot of fuel and very little timing) and increase bit by bit as you go. A stethoscope to listen for knock and a dyno to tune it would be awesome.

A tuner will charge you a **** ton of money for something that he probably doesn't have a clue on how to do.

Think ill keep my eye on this thread; See how it develops...

theres a booosted Altezza down here...boosted black top... hks everything. came like that from japan

That's what worries me, If I end up S/C or T/C, am I going to be able to find a good tuner that won't waste my time or money. And if I can't my learning curve is going to be pretty steep....

Right now I've PM'd a guy about getting a greddy emanage ultimate that he had installed on a 90 alltrac... I'm assuming I could make it work. but at 400$ (what he's asking) it's a pretty hefty investment to be unsure....

[Syaoran]

The e-manage works on practically any car. You just gotta wire it in. It works on engines with MAFs so it should work on yours.

The supercharger idea seems interesting to me, because both the BEAMS and the SC work best at high RPM. Seems like a better match than turbo. May run into mounting issues, since the 3S-GE is tilted back slightly.

Should be plenty of space behind the block....

But I agree, the SC may be better. One reason is the lack of turbo exhaust manifolds, or even aftermarket ex manifolds period for the BEAMS. Just depends on if you could adapt cheaper parts that work IF your goals are low amounts of boost. I've been trying to acquire an old GM supercharger off of an old buick regal to see if there is any way to dis assemble and mount it up... namely because those parts are plentiful and one could reasonably get one for cheap if you knew where to look

[Syaoran]

A supercharger isn't better or safer than a turbo. Turbo lets you do much more than a supercharger. If you want the turbo to work at high RPMs only, you can put on a GT35R. If you want to compliment the BEAMS, you can do so with a smaller turbo, have it give the engine a little torque before VVT-i then a huge boost in power when the VVT-i goes on.

The supercharger will take away low-end power in exchange for a tiny bit (compared to a turbo) high-end power... And like I said it's not "safer". It would take a lot more fabrication than a turbo.

If you wanted, you could literally weld a flange at the collector of the stock header and put the turbo there. You could cut your stock manifold flange and adapt it to a previous-gen stainless steel manifold (like the 2nd gen 3sgte tubular manifold)... etc etc.

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.

[ricochet1490]

what do the pros think?

better yet....

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

[delusionz]

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

[delusionz]

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

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

[Syaoran]

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.

[Neon90424]

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