4AGE turbo..... again

[3T-Rona]

Hi all, sorry for reposting but i would like a straight up opinion on building a 4AGTE. I wanna build an engine thats gonna by used as a daily driver/weekend racer so no massively expensive shit. Budget isnt massive but i dont wanna cut corners, i would rather wait that xtra 3months than have an engine thats gonna blow its arse out 20km' dwn the track.
I no there r a lot of smart mutha's on here so i'd love advice.
Also if we could please refrain from turning this into a 20v vs 16v screaming match
Thanx all

So what are you asking exactly?

[3T-Rona]

Hmm advice on building a 4age turbo, what block to use, what crank, what bearings to buy, what head to use etc

[mike simmonds]

standard blue top turbos are daily drivers on low boost, im guessing that would b ur cheapst option

[EVLGTZ]

Or if wanna go a lil more serious and run say up to 15psi, go for a 4agze and swap s/c for turbo on that. Std ecu, injectors, and fuel pump fine for upto 15psi.

Basic setup would require custom manifold, turbo, intercooler, cheap bov, intercooler piping, change of intake manifold, oil feed and return lines.

Some good details posted by matt dunn in the link below on changing gze to gte viewtopic.php?t=21876

If more serious still, then bigger turbo, injectors and fuel pump, aftermarket ecu etc

The basic setup can yield some pretty good results tho.

[Mr Revhead]

what have you got now?
if you have to buy an engine then silvertop 20v is the cheapest and easiest to get.
for the price difference between that and a 4agze you can fully rebuild it with gze pistons and good bits like TRD bearings etc.

if you have a 16v redtop, then the same thing applys.

all 4age cranks and rods will take turbos (cept maybe ae111 rods) the later ones will take a bit more.

i reckon it all comes down to what you have now, and how much boost you want to run

[3T-Rona]

I dnt have an engine at the moment, im gonna gather all my info b4 starting so i can get it done as quickley as possible so the starlet is off the road for the least amount of time as possible.

well said karl... well said.

[Bazda]

bro.... 3t all the way.
4ages have too many valves.

hahaha



jsut get a ae101 gtz or ae92 gtz front cut, take the sc off like evlgtz said and go for it.
My setup is pretty cheap, still use the standard ecu etc, use the car everyday (uni, work blah blah) and also go to meremere when ever I can.

[event2]

wat turbo would ya use?

daily driven running 14psi?

cheep set up?

woulda turbo off a gsr lancer b about right? or off a evo gsr? or r they the same turbos??

[Bazda]

gsr turbo is small, go for an evo one.

Yes but that is changing from a GZE to a GTE.
Doesn't cover the internals.
If i was starting from scratch I would not start with a GZE as they are too expensive.
Start with a smallport redtop if you want 16V or a silvertop 20V if you want 20V.

Whats your email address?
I'll email you some info I have on conversions on 16V and 20V

[event2]

if i was looking round for an evo turbo to convert a 4agze from supa charged to turbo. whats would i be looking to pay for a evo turbo? am i even looking in the right direction looking at evo turbos or would a wrx or turbo off some other car be better? for daily driven conditions?

[Lloyd]

It really depends on what you want as far as power, where you want the power, lag and various other things. I've got a T3 on mine which comes on full boost at 3500 but you have to wait a while for it to kick in when you put your foot down and it pulls hard all the way to red line and furthur. If thats what you wont, get a decent sized turbo. If you want boost lower and faster at the expense of top end power then get something smaller like a TD04 or T25, T28 etc

[Bazda]

starting from scratch......with a small port redtop, if your going to build this up with forged internals then its going to be way mroe $$$ than buying a 4agze eng!!!!!

u can go smallport redtop, decompress it, link ecu, etc etc, but then thats also going to cost heaps cos u have to run a aftermarket ecu!!

so still the cheapest option for u is to buy a 4agze eng and u can still run the standard ecu, and the internals are very strong as well.

[Caveman]

What sort of power do you want to make?

gze engine, drivetrain, computer. sort out a turbo manifold, ct26/ct20b with intercooler, 12-14psi should be good for at least 140kw

OR

i suggest a red/silver top, use gze pistons, ct26/ct20b, computer, decent sized intercooler. Boost around 6-10psi and you should be right. Anything more than 10psi would need better running gear, which in turn would cost more money

I think you'll find that they will be about the same if not the redtop way will be cheaper. A GZE is vary rare and expensive these days, and the only difference is the pistons which are only about $100 each.

i agree wit matt there, id rather just swap stronger parts ie rods/pistons, instead of startin wit GZE.
Im just rebuilding my bluetop with recond OEM internals, with goodys like aftermarket shells, rod bolts etc. so itl be a strong N/A, get used to the car, engine etc etc, then later i might upgrade to a little boost..
but with boost comes expenses..

-intercooler
-piping and fitting
-exhaust
-injectors
-fuel pump
-wastegates
-ECU
-BOV etc etc

And then with all this power u gotta think about driveline..

[3T-Rona]

Yeh but i gotta upgrade fuel lines and pumps to begin with ne way, and ill also run a strong driveline form the start so the extra power wont be a worry
