1GGZE - good base for strong NA motor?

[Johnzoku]

ok, time for another of my thinking out loud threads (i know i know but it could help someone in the future as well, etc... )

i have a Gz10 1gge soarer sitting at home, with a W5X box, xmember, tail shaft, pedals, excedy clutch etc... ready to go in.

i also have a gen 1 1ggze minus a few bits, loom and computer, belts, iscv etc..

the idea was to put the 1ggze into the soarer but im having a pain of a time finding loom and a ecu to use, i could get one from japan but by the time i get all the missing parts i'd almost be better off finding a front cut for a few hundered more or turn it into turbo which involves a bit of time/cash etc... to get everything which brings me to my question.

im a big fan of NA, altho a supercharger would of been great ive seen a few awesome examples of Na 1gge's around and though it might be better just to combine the two engines into one and see what happens



i know compression ratio's are different but is there any differences between heads like would the 1ggze head flow better or is just the same unit. are the 1ggze pistons/rods/cranks alot stronger than the 1gge to warrent the hassel of switching blocks over? would running a 1ggze as an Na take quite alot more abuse than a std. 1gge?

also, is it possible to run a 1ggze crank angle sensor and some after market coil packs (or even std. ones) to run on 1gge ecu. i know the 1ggze coils fire 3 at time in pulses rather than how the normal dizzy fires.

ive done a few searches and found not much on this so far (as always ill keep searching)

and if your wondering where that 1G came from then look below...

low compression will be a bit shit.. unless you keep cams small (but lumpy)

NA might sound good on ITB, but by the time you set up ITB, you could have bought turbo bits..
but in the end.. an NA 1G in a soarer will sound good, but be slow as a wet week (or, not quite as slow but..)

[Johnzoku]

sorry for the noobness on this one but is there a possiblity of raising the compression ratio with a thiner HG on the Zge or does the lower compression ratio have to do with the pistons and block as well?

it will be a long time before i'd Put ITBs on it... this is just about a basic set up for now.

also thats the cheepest ecu ive seen so far 50 bucks+around 50 more to get it here... not bad.

[Johnzoku]

AHH found a bit more info to help it along

I will say again as I did in the other thread, all rods are the same length, all pistons are the same diam, all pistons have the same pin height, you can interchange any piston from na to turbo with no difference in compression height. You can also interchange early turbo rods/crank and supercharged rods/crank.

lower compression = pistons or chamber.

thinner gasket maybe, but really you can only gain 0.2 or 0.3mm there safely. deck block or head?
you really need to work out if the rods or crank are different. and even if they are, are the NA versions any less suited to what you want? ie, not such high revs, no ITB, probably not wild cam etc...

$100? hmm if you are lucky. depends on local postage as well. shouldn't be more than $150

[gianttomato]

By the time you build up a decent NA 1G, you could have bought a BEAMS 3S and some ITBs off Glenn and crap all over the poor 1G from a great height.

[Johnzoku]

ahh fair enough... i was thinking a raise in compression would involve decking the block/head and a new gasket.

the guy i use is pretty good so i think about 100au would be close, maybe 120

a beams 3s would be pretty sweet but im just trying to use the parts i already have. if i spend around 1g to make a 1ggz an NA i'd be happy if it results in a stronger engine than the normal 1G.

[oldcorollas]

hmm, 5000 auction + 500 bank fee + 1500-2000local postage, plus up to 4000 postage to aus (maybe a little cheaper)
$120 if they use exactly current exchange and charge no fees at all

[wilbo666]

Crap idea.

Put a turbo on it and stop fluffing around

You could get a modern 1G-FE - is likely to make more power, with a nicer torque spread, using less fuel

[Draven]

and still be slow

[jimmy_a]

Chances are it might be strong, but booooooring.

[Mos]

No slower than a 25+yo 1GGZE with no blower....

[jimmy_a]

LOL. I looked at an s14a 200sx ages ago, NA. It was ridiculous. So loud but uselessly slow. I think it's a bit pointless to be honest, especially considering how cheaply you can pick up decent 1jz's for.

[ill-minded]

i don't think speed was the aim to this

the sound of one of these things on itbs and some cams would be interesting though...
