boost bug bites

[AE92blktop]

Hey guys I will try to keep this simple
What i have is an aw11 4agze and a ae111 black top both running and in good condition. I would like to end up with something along the lines of a 170kw 4agte, would the gze been such a early version be able to take this safely or would i be better off buying forged goodies for the black top?

I was thinking of using the black top head on the gze bottom end if the motor will be good enough

as long as the 4agze is in good condition, with right turbo computer and fueling stuff, 170kw should be obtainable easily.

Both motors are in very good condition with the gze having done less than 80,000 so thats good to hear, I was thinking gze bottom blacktop head with a good clean up, i have the g box from the aw11 as well which i hear can be made to fit a fwd application as for the turbo i have been told a td05? or a subaru turbo works well (i will look further into it before deciding). Can you get a computer with a 4agte base map as I would like to wire it and get it running myself then get it fine tuned?

Search buddy. The subject has been done to death.


If its only done 80 tho km, don't take off the head, just run the 4agze as is. 170kw would be easy on that.

Will need bigger injectors, if you use the 16v head its top feed. So grab a set of 440, VR4s, or better idea would be 510 or 550 evo ones.

Better grab a fuel pump to be safe.

Go big turbo. T3/T4 style. Or a td05 will do.

Ecu wises, go link G3, around $1300, wire it in yourself, get it running with a laptop computer. Then take it straight to dyno man/tuning man with a wideband oxygen and get it done.

No need for 20v head. 170kws would be easy.

I got 150 on 12psi on my early gen 4agze. Had std injectors though, so I couldnt go further.

Around 18psi and should be around 180kw.

Cheers for the info guys I know its all been asked before and i did have a look but for some reason you cant go past having your question answered personaly
I was mostly wondering about the gze strength as i have not read about many people using the early ones out of aw11s

[slighty_sykotic]

Probably the strongest.

Got the biggest conrods you can get in a 4age.

And its low compression.

Same block and crank.

[AE92blktop]

Good and strong thats what i wanted to hear thanks alot

hmm i crave boost yet i like high revving NAs, shoot looks like i will be building an extension onto the garage!

As per above, 170 is very doable. Dont even need big t3/t4 as someone said. ht18/rb20exhaust turbo will make 195 as per my sig

[TRD_ZERO]

You also have to look at it like this......by say putting the blacktop head on the gze engine or putting forged pistons and bigger rods in the blacktop, ud have to get an aftermarket computer to get it all tuned up and running which will end up being really pricey. Or for the power figure ur looking at you just keep the gze engine as is and turbo it as that wil work best and hell cheapest.

That's the same turbo I've got for my 4AGE. I'm going for lower boost than that though (I'll have a fuel cut at 15psi). Any idea on how much power it'll make with say 7psi and how much at 15psi?

Cheers.

bugger all, put more boost in it cramps

I made 126kw atw on 9 psi before the tune, still managed to pull mid 14's aswell with that power. As above dont really need a big turbo, although my car made 190kwatw on 15 psi, so good flow and less restriction with big ex/housing can certainly help with things

Ha whatever Mr 25 psi! I'm turboing the stock motor Bredon, so I don't have the goodness of 4AGZE pistons to keep things together.

Not going for massive power, just a nice streetable setup. I've still got an open diff as well!

[narlystarly]

think i made 165 on 14-15psi, something like that, will try find dyno plots.

Sweet sounds good cheers.
I've only got 365cc injectors (4AGZE), so I'll be limited to about 150kw at the wheels with those aye?

[narlystarly]

Best to go find some vr4s or evos. Pretty cheap in the long run.
