4a-gze internals...

[kingcorolla]

correct me if im wrong...

i take it the 4a-gze conrods/bore width are the same as the 4a-ge,
but compression is lower due to forced induction. So is it the stroke is not as long
as the 4a-ge, ie, shorter crankshaft throws, or bigger combustion chamber in the head? Or even craters in the piston crowns?

someone tell me how they lower comp on the 4a-gze.

(i take it the conrods and the piston width are still the same if different pistons)

Bore and stroke are identical, as are the conrods, and crank to any 7rib 4age, only thing that is different is the pistons.

cheerz dude, guess ill go 4 the forged 4a-ge pistons then! jus wondering if 4a-gze pistons would go into 4a-ge, unless i do sum like, rip the shit off the head face!!

Yip 4agze pistons will go straight in, however all of these have 20mm gudgeon pins and the early 4age's have 18mm. Which model 4age do you want to put them in?

[kingcorolla]

ye i got redtop (20mm)

wouldnt putting 'GZE pistons in lower compression??

sure will

[kingcorolla]

but this isnt 4 a turbo application. jus wanted to see if i can save alot ov cash by goin with o/s 'gze pistons instead ov forgies...... $$$$$$$

i can still go with crank & rods tho

[Bazda]

why do you even want to put 4agze internals in if your not putting a turbo or s/c on it???

4agze internals will prob make it slower as they are much heavier than 4age internals.

[kingcorolla]

jus for overall strength really. able to kope with high hp without me having to rebuild again.
lightening the flywheel & getting internals ballanced will compensate for heavyr parts.

[Bazda]

well to keep your compression up you wont beable to use the 4agze pistons.

you could prob use the rods and crank, but these items usually dont break in a 4age, even when applied to a turbo conversion.

[kingcorolla]

exactly my point

[Bazda]

exactly my point

which one was yoru point, the compression, or that standard 4age internals can handle boost

[ants_ae92]

Intewrnals for both 4age, and 4agze are the same arent they, according to to one other post on this site it is. putting gze pistons in an na application would have to be the dumbest thing ive had all year. You will lose power, torque, and fuel efficency by doing so. Increasing the compression ratio of the motor will increase power, and fuel economy. as you won't have use as much fuel to get the same bang. eg compress same amount of air more with same fuel = more power. So going backwards by reducing c/r you are screwing yourself over for what strength. The standard na 4age pistons are very strong and dont need replacing!!

For a turbo application you are effectively increasing the compression ratio by forcing more air into a cylinder so you need the lower compression pistons. But not for a naturally aspirated application.

If you want more hp/kw in an na application try increasing the compression ratio.

4agze early(bigport) 8.0:1
4agze late(small port) 8.9:1

4age blue/ early redtop(Big port) 9.4:1
****4age Redtop smallport 10.3:1****

This is what you need. 4age redtop small port pistons. Still very strong and a higher compression ratio. 4age internals are very strong don't go backwards!!!

Someone please back me up!

[Bazda]

correct!

[kingcorolla]

so ur sayin that my factory pistons are capable of handling 150hp+ without even breaking a sweat? thats cool. When i posted this topic, i WANTED to know what reduced compression in a gze, so i knew what NOT to replace. But i am contemplating a gze crank and conrods for more strength, any objections??

[kingcorolla]

BTW, this topic is about internal strength, not incresed compression or power.

sorry dude, just red it properly!
thats what i needed 2 know, cheerz!

drifter4ag on here is running 14psi into his standard bluetop engine making 174kws at the wheels!!! put that into hp at the flywheel and it's near 300hp

[gdsup]

by the way gze/redtop0 (i.e crank/rods) internals are heavier and will make it slower, go the bluetop bottom end, may have been said above but cant be bothered reading through the endless bs

[kingcorolla]

fuk that idea then. cheerz 4 savin my wallet guys!

anyone had expiereince with gapless rings? to help eliminate blowby and compress close to 100% charge?

sounds like a good investment to me.

......mite burn more oil tho..
