Little bit Tuff 1ggeu? Mods for the NA 1GGE motor

[bunkyt18]

I'm thinking of doing something to the 1GGEU I have in my XX. I'm hoping to do a few things that will increase it's performance. So I have gone by the usual route of replacing exhaust with 2.5" jobbie and intake mods (although I don't think the pod Filter is doing me any favours so will be building a CAI setup too).

I have a few questions;

Will using adjustable Cam Timing gears be of any good with the stock ECU?
Would I gain more benefits using the above cam gears with aftermarket ECU?
Does anybody know of similar attempts to get some more grunt out of these motors?

Further down the track, I'm thinking of either a NA/ turbo/ or SC conversion or a more involved NA buildup although I'd prefer to leave the insides of this motor alone because of;
1. cost
2. what seems to be a lack of available aftermarket performance parts (hi comp pistons, cranks cams etc for the 1G motors and in particular the 1GGEU

Any help or ideas would be gratefully appreciated.

Thanks

Adam

Bluddy hell!!! 43 perves and not one response. Well I may have to post another one in the tech section once I have finished the work up on the humble 1GGE.

throttle bodies and all that hoo haa comes to mind.

ooh oooh oooh NOS 2 of the big ones /end F&F quote.

Probably because you don't want to do terribly much to the motor - kind of limits what you will get out of the motor. And then you're going to ditch the whole lot and go forced induction anyway.

Without cams, all the adjustable cam gears will allow you to do is move your available power around. That may (or may not) be handy. Any gains from an aftermarket ECU will more likely come from tune rather than addition of adjustable cam gears. I know of attempts to get a shitload of power out of these things, but halfassed attempts, no, apart from yours .

Beyond the usual easy stuff, anything else is a WOFTAM. There are better 2 litre NA motors to play with. There's a reason you can pick them up for a slab of beer .

Best mod would be to either bolt a turbo to it, bolt a supercharger to it, or replace it with a factory turbo/super motor.

Or replace it with something completely different.



You may need a tin of this if you plan to work the motor.

oh come on, the 1G aint that bad... heh

[crowncustom]

Well I don't think they are that bad.The Mk2 Rona I have the 1G-GE in goes extremely hard.Normal mods would be zorst,cams,head work etc.

Hmmm interesting opinions, thanks for the input guys. I used to always feel a little sorry for people who would ask the 'I have this, what can I do with it' style of questions. Now i am one of those poor unfortunates ... Still there is a lot of value in getting other peoples opinions and or views.... sometimes lol.

Giant tom, there is no set plan for what will happen with this motor... maybe nothing. I'd be interested in what attempts were made to get the 'shitload' of power from a NA 1GGEU.... if you would like to share...

Cruzida, thanks for the polish tip.

Yeah Brett, I reckon they are a nice dependable motor that could be tickled up into a decent street donk. But what would I know...I'm just ignorant but curious question asker...

The topic of this post is pretty clear, I'm not asking whether the 1GGEU is a POS or not, just want to know if anybody had had any cracks at getting these to perform.

[gianttomato]

Look, I was probably being a bit harsh - they're OK for the price. If you have one already to play with, go for it. Typically, I have seen them go where 18Rs used to be and it was a great conversion.

Bunky, a lot of work went into it. Lightened crank, rods, forged hicomp pistons, a lot of head work, cams, valves/springs, ITBs, headers, zorst - was a race motor. I can't remember exactly what power it made - extremely hazy memory seems to recall 250hp flywheel. Cost many many thosands of dollars - not berating it - it had to fit in a particular class for circuit work and it was felt this might be the motor to go racing with.

Buy a 1GGTE. Cost $750. Use search to see what they're making but it would be more than that with a factory ECU, FMIC and a bleed valve. If you really want do the NA thing, I suggest a BEAMS 3SGE rather than tweaking a 1GGE - 210 hp out of the box with a factory ECU and will probably be cheaper than working your 1GGE.

My humble opinion of course.

[CrUZida]

The only reason I say what I said, is because no matter how much power/response you get out of the 1GGE, 200Nm peak in a 1300kg car is never going to be something that will rock your socks.

For a couple of grand you can drop in a 1GGTE or 1GGZE and have a lot more power, a lot more torque, and a lot more reliability.

If the car was a sub 900kg car, my response would be different.

If you are looking to do up an N/A engine and dont want to open up the bottem end, then basicly do these mods...
ITB's, cams, headwork, extractors, decent flowing exhaust system and top it off with a decent standalone ECU. I dont know the results you would get from doing these, power and tourqe wise, but it would be much better then stock engine for sure.
Might not be cheap but you would get nice responsive engine and more powerful, not as much as turbo or s/c obviously but it would still be nice result. Dont let anyone put you off doing it, if its something you want to do then go for it, if your just after an opinion then it might be better to look at turbo or s/c or an other engine completely.
If you think that your going to turbo or s/c down the track, just do it from the get go.

Cheers

just put a wet nos kit on it and once you blow it up, it was about time a 1ggte went in it

[bunkyt18]

Thanks guys, all this stuff is good. Hope I have not given the impression that I'm a 1GGEU obsessed little fanboy. My actual personal consensus runs pretty much along the lines of what has been put forward by youse in this post.

I find it interesting that the 3tgteu (an engine I have some knowledge of) has a stock hp rating very close to the 1GGEU yet everyone (well maybe not everyone) waxes on about these old T motors like they are the duck's proverbial. People get all excited about putting these in TA's and celicas yet these cars weigh around 1300kg's? Or is it 900kg's?

Anyways, thanks again for your words of wisdom.

And to ViPer, 'Naws and I need it by tonite.!!!!'

[CrUZida]

Older Celicas are around the 900-1000kg mark.

Also, with the 3TGTEU, the hp rating may be the same, but that is at stock boost.
Wind the boost up, and you'll have a lot more power than a 1GGEU.
The other thing is the torque. With 10-12psi in a 3TGTEU you'll have about 50% more torque than the 1GGEU.

When it comes to working an NA motor you are basically limited to ~100Nm/L, regardless of how psycho it is. If you need a faster car then your options become gearing and weight reduction.

With turbo motors you can just add some boost in.


But, at the end of the day, if you want a little project, go for it. Find some RB26DETT ITB's, get some extractors off YahooJapan or build them yourself, port the head yourself, pop a megasquirt ecu on it, get the cams welded/regrinded and you'll have a nice little toy.

Look I'm an N/A fan all the way, and probably spending more on my N/A 2J than I should to get power out of it. Primarily doing this because of the cost associated with getting a TT engine, that and I can't insure myself with a TT for a few years yet either...

In your case however 1G-GTE's are alot cheaper than 2JZ-GTEs, so I have to join the rest and suggest you look at a forced induction route.

Extractors if they are off the shelf will cost you $600, if they are made for the 1G, and if you need to get them custom made it'd probably be closer to $800-1000. Cams and cam gears are also pretty pricey and then you'd need something to tune the stock ECU or go stand alone to get the most of your new mods. So you are probably looking at $2500 to get some quality power out of the 1G-GEU unless you can weld and put alot of this stuff in yourself.

Get a 1G-GTE for around $1000 and you'll have a whole lot more fun than N/A 1G. Having been for a ride in Rods Celica with stock(except FMIC) 1G-GTE, it was a blast, and certainly hauled ass!

Then again, if you want to be different, mod the 1G away Just bear in mind getting power out of an N/A is always expensive....I know I've contradicted myself a few times now, but just my thoughts on the matter....

But, if I was going to mod a N/A engine I'd.....

- New spark plugs
- New HT leads, new Dizzy rotor and oil change
- You'd be amazed how much of a difference they make for starters....
- Extractors
- High flow cat, and cat back system...
- CAI or get a high flow panel filter for your airbox, or replace with a pod if you can get it near the front of the car and get plenty of cold air to it, don't just whack a pod in the engine bay like lots of people do...
- SAFC or something to meddle with the A/F's a bit
- Cams
- Adj. cam gears
- Port & Polish...
- Stand alone ECU, Autronic or Motec
- Forged internals and balance and blueprint for high revving goodness
- Up the compression and idle the car at 2000RPM with the lumpiest cams ever...)
(Yes that's the dreamlist for my N/A, I'm up to the cams bit, but baulking at the costs...)
