What turbo would create more lag on a 4AGTE??

I was loooking at getting GT28RS, but due to the cost of manifolds getting made i spotted a HKS manifold for $399USD that is a T25 flange. So what turbo would make more lag on a 4AGTE in stock form...
Garret GT28RS or HKS GT-2540?? they both make 350bhp, i wont be looking at making any more than 160rwkW.

A very general assumption would be the one with the smaller exhaust housing/lowest A/R would have least lag. Both are good for well over 160rwkw though so you won't have a problem getting the top end you are after.

if your only looking for 160kw atw why not look at a smaller exhast housing both turbos should be good for close to 190kw atw...
the gt2540 shouldnt be that laggy on a 4agte but i guess it depends on what your defintion of laggy is

for that power level I think you have the wrong choice of turbos, a TD-04 might be better. But I could be wrong I havn't tried it

Both turbos have a T25 flange, right?
Surely cost must be a huge factor here... GT28RS at $1395 or HKS GT2540 at $3k+ ??
As others have mentioned, exhaust housing A/R ratio will have a fair impact on turbo response, i'd be sticking to a 0.64 housing for the little 4AG, not 0.82.
Browse through some silvia/200SX forums, many guys there have used both turbos, and there are mixed reports on the HKS GT2540 in particular, some find it significantly laggy on a 2 litre SR20... but they have the potential to make in excess of 240rwkw, so perhaps you might want to re-assess your power target!

the car is been setup for drift, i wanted that turbo incase i want to make more power later,and my friend has it on his S13 and i like the power band. I only want that 160rwkW due to the internals on my ZE i thought they could only handle 180rwkW before things started to go wrong.

what car will this be in???
if its in a sprinter 180kw atw may cause you more problems with the driveterrain than the engine.....
The stock gze is roumoured to be good for 200kw atw.... supposedley people have made them hold together at that level...
if your thrashing it all the time you might have durability issues

well the car it will be in is a 1984 ke70 corolla, it will run a KAAZ 2 way, with hilux axles or landcruiser ones, i will be matching engine to a W55 or W58 and the T50 would fall apart at the site of that number 160rwkW. It will be used for drift and once a week for practice, so basically it will be thrashed. Does anyone have a idea of a more durable power then? or parts that i could use to strengthen internals and improve durability.

A w5x and hilux diff will take that kind of power all day every day! I would be aiming for more power with that driveline!

it will take 160kw atw fine... I am planning to run close to 190kw at in my bogg stock gze but at the end of the day getting a stock motor to last under high stress you need good support systems like surge tank oil cooler good aftermarket ecu with spot on tuning (most important) a fuel system that isnt at 100% duty etc etc...
You would need these support systems even with a toughned motor...
it dosent matter how strong the motor is if its being bounced off the rev limiter all the time its going to shorten the life of it considerably....
if it were me id run the stock motor until it got tired or went bang then rebuild it with stronger internals when the time came thats my 2 cents

thanx, i will try not to leave it on the limiter all the time, still in the process of building it, i has just been rebuilt and not ran in yet. I have a microtech lt8s, going to get a pwr cooler and oil cooler, running probably a vl style fuel pump 400bhp one or something, got a surge tank sitting in room.

Ian I am pretty sure you will need a hilux rear end to use the hilux axels, they wont go right into a T series...thats a lot of cash dude...
personally id go the GT28RS the 2540 is too big for a 4AGE for drift...
the T series with KAAZ two way will hold 160rwkw fine, simon had one behind his CA spoonter and it didnt miss a beat

sounds like your on the right track you may need a lifter pump to fill the surge tank

the vl pump is external, what would u suggest for a lifter pump for the surge tank??

it dosent have to be anything special it just has to keep the surge tank filled im not 100% sure what youd use on a car that was originally carby but on a efi car usually the standard fuel pump is used as a lifter

Use a cheap low pressure low flow automotive fuel pump, the ones used to replace mechanical pumps on carby cars.

nice sounds good, anyone got a diagram of how it goes together as i would have a clue.
i thought it was like this...
tank ---- fuel pump ----- surge tank ----- engine -----
