4agze lack of grunt

Hey there.
i really think that my 4agze is running very underpriviledged and not entirely sure as to why. I have put a 4agze into a Ke20 and it really wanted to fly. i went and bought the same modified vehicle and it still has grunt but not nearly as much as the other.
just curious as to any differences there may be i think the air intake and intercooler are worse than my old car but that shouldn't take away as much power as it seems has gone.
also does anyone know if there are any kits to put a sc14 (1ggze supercharger) onto a 4agze? cos i want more power... can there ever be enough power. but yeah any ideas
Regards
Ray

Can't help you on the first problem - are any error codes being thrown up by the ECU ?
For the second question about the SC14 replacing a SC12, its been written on this forum that someone has tried this already, and there is not the physical space available to make this fit.

Re the SC14 fitment. You'll need to put together custom brackets as the SC needs to sit out further from the block so as not to foul the cooling lines. Despite earlier comments these do indeed fit.
Are there any other differences between your cars? IC will makes a difference if its not efficient. Same with the IC pipework. Did the other setup have a larger crank pulley? Thats the best bang-for-buck with the 4AGZE. Maybe a later AE101 SC with the smaller SC pulley (more boost).
In a KE20 (AE20 now?) it should fly. They are quite light.
Just my 2c

Is there something fundamentally different with the engines? Perhaps you have a MAP sensed one and the underperforming is an AFM one?
Boost leak?
Headgasket?

thanx for the suggestions, i don't think it is the pully both were upped to 14 i believe, it may be a different model maybe my new one is an ae92 and my old a ae101??? any way to tell the difference? same with the map sensor i know what it is but i don't know what it looks like  not completely up with everything
better not be a headgasket i will really be peeved if it is.
it may just be that it needs to be retuned. it really ain't very fuel efficient at the moment either, only about 250km per tank and its a 30 - 40L tank i believe, so for a light car thats really bad.
is there definately not enough room in a ke20? it is a RWD conversion...

Hmmm,
The late model AE92 GZE and the AE101 gze are the same basically.
If doesn't have an AFM (Airflow Meter) before the intake, then chances are that it's a MAP sensed model. The MAP sensor is a small black box that's probably been bolted to a bracket on the firewall.

thanx for that info.
i am seriously considering the sc14 SC at the moment, its about 400 for a second hand one just wondering if anyone knows how much i would be looking at to modify the brakets and shizen to make it all fit.
also anyone in victoria that would be able to do it for me?
i am not really an expert when it comes to modifying brackets when all i have is a hammer

You could try Toby Hunt @ Meridian Motorsports.

I would 2nd Toby @ Meridian and suggest that you get them to have a look at the car before buying the SC14. They have quite a bit of experience with the SC motor and Toyota's in general.
Is the car running a O2 sensor? A stuffed sensor or one that isnt fitted will give shit fuel economy.
I would spend the $400 to get the car checked. I have been in a ZE KE20 and they go very well. The difference between AFM and MAP is negligible between the AE92 and AE101 motors (AW11 is different with 8.0:1 compression).
Again, just my 2cents

There are a myriad of reasons why it may be "off tune".
Is this one running aftermarket fuel injection? Was your last one running aftermarket EFI.
Spark plugs?
Your exhaust may have taken it up the tail pipe (ie fucked/ blocked cat etc.)?

again thanx for the input pplz, i found out that it is not running constant boost!?!?!?! i am thinking that may be a real issue. also my a/f ratio is 19??????? i am thinking this is bad too?
i will check the spark plugs and just had the exhaust looked at.
by the way does anyone have an address for topy hunt at meridian motorsprts?

after replacing my dead O2 sensor, i didnt notice any real difference in fuel economy
