RoadRash:

What have you done to your fuel system? Bigger main injectors, any sub-injectors, heavier fuel pump, return line, ... ? Or what are you planning to do to avoid the leaning?

←

nope your technically the first..............

however there was the 1g-gte....

←

I've found a 1g-gte engine...with twin turbos.................... :winky:

←

Couldn't use 1g-gte, even if I found one... Or if it could be operated with the 1g-fe's ECU, maybe then. OBD-II has been mandatory since 2001, and I won't pass MOT without it.

Are 1g-fe and 1g-gte internals inter-changeable? If I found 1g-gte rods and/or pistons, could I use them?

Toyota Electronics are a hard nut to crack.............and i think there lies one of your biggest problems.but as i said, good luck

←

Thanks Mat(e) to remember me...... I KNOW!!!! :tsktsk:

Not only to prevent the fuel cut, the hardest thing where everybody had problems on a turbocharged IS200 is to get enough fuel.

The fuel system is weak, mine leans out over 0.3-0.4bar.

Don't think that 2 turbos would spool up soo much earlier..... 1 turbo on 1L displacement.... not that much.

And it's difficult to make them running synchron..... but quite a difficult project.

And it would be a really good job if you can realize that. :winky:

Anyone else here with twin-turbo'd 1G-FE?

ok.im only saying.............nothing, i repeat, nothing is a walk in the park

OK, maybe I should have put the "walk in the park" in quotes...

And what comes to electronics, I've also noticed that IS200's ECU is way too "smart"... But I'm counting on bigger 440cc injectors and Greddy's Boost Limiter Cut -feature. With that you can clamp the voltage from the MAP to ECU, and make it never see the boost, so it won't do the fuel cut. Under boost conditions the Emanage will be reading from it's own boost sensor. I also have AEM UEGO to take care of the correct fuelling.

And if these won't do, I also have O2-simulators, to prevent the ECU making it's own corrections (=leaning back the mixture).

Think I'll be even in the half way with these?

you have 2 mechanical actuators to control there aswell.......they may well cause you problems

←

I'll control the actuators/wastegates with the Profec e-01. It's got very powerful solenoid made for the BIG turbos, so it shouldn't be a problem. I'll have to splice the vacuum line, and the lag for opening the wg's will double, but if the initial lag is 0.01sec and it doubles to 0.02sec...... :D

SPACE........or lack of it.

its impossible to list all the potential problems, but i think you will run into many

←

Space shouldn't be a problem. The guy who's putting the turbos under the hood, has built e.g. a 402hp/418Nm Golf 1.8T, and a 2.7L V6 Bi-turbo Golf(!) as well. He said that if he can fit a 2.7L V6 in a Golf and even two bigger turbos than mine in between the engine and the firewall, then my car is walk in a park. SOOOO much more space under the bonnet.

i think you will have lots of problems getting this set up, u would have been better using  1 turbo

However good luck, i hope to see it running real soon

←

What makes you say that?

What kind of problems would you think I'll run into?

when do u expect to have the items fitted/manifold made etc as at the mo the turbos are just sitting on a supercharger cradle.

←

Yes, you're right. This was just to see if we can make them fit under the bonnet. I'll be gone for a vacation in Feb, so my friend will be making the manifolds and installation then, while I won't be needing the car for two weeks. The piping, IC and eManage are already fitted. Just waiting for the turbos...

Wow..... heavy mod mate! 

But 2 turbos on 2.0L....  don't think it helps more than only 1 turbo.

But awsome work, did you do it by yourself??   

←

Thanks! :D

Reason for using two turbos, is that it's much easier to make a manifold for only three cylinders than for six. So that's why I get two 3-piston manifolds = 2 turbos... :winky:

And by using two turbos, you can make 'em smaller and still have the same output. And as they are smaller, they spool earlier = better low/mid torque.

All the piping, IC and eManage installation and wiring I made myself, but my friend is going to make the manifolds and downpipes for the turbos. After that I just have to tune it with the eManage.

wicked. Good luck ! I've got forged pistons and steel rods in mine....hoping for 280 with a stage 2 s/c pully kit then a 100bhp NOS shot.........waiting until its run in..........

keep us posted !

I'm interested in those pistons and rods as well. Where did you source them? As to my knowledge no company has those, I take it that yours are custom made, right? Wiseco?

I will keep you posted.

just wondered.........looks like the 1g-fe engine...expected BHP ?

←

Maybe because it IS 1G-FE... :P

Two K03's can support well over 300 bhp, but without new pistons and rods, and before lowered compression, I'm aiming at about 250-280bhp...

mmmm.........where are you based ?

←

Helsinki, Finland. How come...?

Two pieces of KKK K03 going in with custom manifold, piping, IC, Greddy eManage and Profec e-01 boost controller... :winky:

Can't wait to get it working and on the road!

Let me know what you think.

p.s. Sorry for the picture quality, I only got cell-phone cam within reach...

Anyone? Mark?

I have not (yet) installed any sub injectors, and the main injectors are also std 220cc, because they should be good for over 250hp (220cc * 6 / 5 = 264hp).

Anyone currently running TTE S/C + eManage combination? Just finished installing S/C + eManage, had a test run, it seems to work mecanically ok but running lean all the time under accel. Cruise is more or less stoich but once accel depressed it goes lean. Under heavier acceleration, there's a fuel cut. I used AEM wide band lamda while setting. If anyone has any experiences with this compination could someone please post your configuration file for the eManage as a basis of my setup. I would greatly appreciate it.

Cheers,

Sami

Thank you All for your kind words!

very very nice indeed, them 19" wheels look too small now, time to get some 20"'s

dubs are already on their way! it's only that correct size tires come available not until later in May...

also agree with Mark about the decals

My car is partly sponsored, so I kinda had to put the decals. I work for both Autostudio and BlazeSpeed, and those are also my sponsors.

I hope to get the pictures of the hifi-installation/trunk very soon.

why do all cars around it look bigger

This ones freaky..how big is that Frontera

Hmmzzz... I don't know...

My friend used a Canon D300 and a huge tele-lens and took the pictures from quite a distance.

Hello everyone!

At last I managed to post some (1 picture, and here's 8 more) pictures of my ride to the gallery.

I've now completed 2 stages out of three. First stage was the hifi/multimedia systems (sorry, no pictures of that yet, but behold, there's something quite nice coming out... ), and the second one was the appearance/exterior (there's 9 pictures of that).

I will post more pictures as soon as I get them. But until then, please let me know what you think!

Cheers,

Also an article in there on the new lexii coming out, including some green ones, an IS350GT and then the new GS......

I know this is a little but does anyone have a clue about the engine on that 350GT beast? I tried a search on the AutoEXPRESS site, but not a word on 350GT...

Anyone had any experiences with this? Seems like a value for the money... :D

As for having a non OBD-II engine management, who is going to know? Would never be checked in the UK.

I don'tknow about other countries (I think it should concern other countries including UK as well, since it's an EU regulation), but at least here in Finland they've started to take read-outs from the OBD-II -system from the beginning of 2004 as a part of the MOT. So a newer vehicle (2001->) won't pass the MOT without the OBD-II in tact.

There's even been some debate in the media of the "dead standard" vehicles WITH the OBD-II not passing the MOT, because they've not been driven "correctly". For the OBD-II to work correctly and for it to be able to complete all its self-diagnostics, the vehicle has to be driven along a certain cycle (includes cold-starts, full-throttle accelerations, high-way driving, idling, etc).

That's why some of those "grand-ma's shop-carriages" won't pass MOT, 'cause those grannies have defenitely NEVER even gone full-throttle...

But other than that, thank's for your opinions chaps! :)

Once the engine is cruising then it will rely more on the O2 sensors to make adjustments and therefore wipe out any effect the mod is having.

But that in turn would negate the piggy-back ecu manufacturers' claims of better fuel economy, wouldn't it? You can't make any difference in economy while accelerating, but rather on cruise. And if the std ecu over-rides the piggy-back's effect on cruise, then there's no use trying to lean the mixture to gain better economy -> makes manufacturers' claims bull...

However for big mods then you need to remove engine control from the standard ECU to something else like the HKS F-CON pro.

I guess that wouldn't be an option, 'cause since 01/2001 the OBD-II system has been mandatory in EU. None of those aftermarket ecu's have the OBD-II (at least none that I know of), and they're all "only for of-road use"...

I've read here some talk about the IS200 ecu's ability to re-/self-learn a new program in the course of time after any changes in the engine's operating environment.

Wouldn't that kind of a negate the stuff that a piggy-back ecu does?

e.g.

- air-flow meter senses "a", and sends it to std ecu

- piggy-back ecu catches the message in the way, alters it, and then tells to the original ecu that the air-flow meter said "b".

- then the std ecu, unlike it anticipated, gets the message "b" and acts accordingly

- if the piggy-back ecu from there on then keeps telling that "a is b", wouldn't the std ecu then change it's program "for good"

I recall one member here telling that he's used HKS' F-con (or Greddy eManage?) and that he'd "maxed out" every setting the gadget had, just to make ANY difference and to fight against the std ecu learning the new stuff.

I'm not 100% sure I know what I'm talking about here, but I guess you got the picture what I'm after.

Any one? Mark? :duh:
