i know this will have been asked before... 4agte

[h8wrxs]

just want to know how to choose what turbo to run on my 4age turbo trueno

ive seen turbo kits for sale with t3t4s and t25/28s but i dont know the difference, i know that td04s are common on these but i know theyre small and i think id want something bigger...

can anyone explain the t3s and t3t4s and t25s etc to me as in the pros and cons?

what recommendations do you guys make?

cheers

My recommendation...

Start with deciding either how much $ you want to spend
OR how much power you want to make.
Then think about if it's for a road car or for the track.

Bazda power with a big turbo might cost $10,000 or more to do properly (yes I know it's a 7agte)

170 kw might cost $5000ish for it to be reliable.

If it's for the street do you want performance OR be to able to brag about peak power? A turbo that will give good torque at 3500rpm might be a little bit down on peak power but could be quicker from 0 to 100 than a bigger turbo.

the t3/t4 kits you see on tardme are too big in most 1600 applications,

you really need to start with the end in mind as ken says.

I made 200kw wheels out of a t3 skyline turbo, HOWEVER i did not do anything on the cheap each part is genuine (not rip off chinese stuff) or its was custom made for the car, the list of stuff off the top of my head goes,

t3 skyline hybrid (steve murch made it)
550cc injectors from evo
walbro 500hp pump (genuine- beware there are copys out there)
Microtech ecu + x4 ignitor
Bosch coil packs + 8.0mm leads custom made
blitz DD BOV (genuine agn)
2.5" stainless exhaust
custom intercooler plumbing
Custom steampipe manifold (action dan)
Tial 38mm wasgate (again genuine ex usa)
I did use a trademe intercooler and have had no problems however

Im sure there is other parts as well that i have forgotten, as you can see a setup like this is not cheap. (i think im close to 20k now but i stopped counting a LONG time ago as it gets depressing ):lol:

bottom line is before i started i knew i wanted to make 200kw wheels.

work out what u want then soemone can recomend you a turbo no problem

[escortman]

u dont sound to clued up on this so answer these qns

are u doing it yourself?
how much do u have to spend?
what are u using it for?
how much power do u want?

[h8wrxs]

im not worrying about the money side of things, ive spent far too much on my car already so i dont care anymore

i just want a fast street car, but seeing as i live in aussie now and im only in nz for a few weeks of the year i want something wicked to drive...

maybe 200kw - 250kw lol not much

me and some mates are going to build it ourselves (they got a bit more knowldge than me)


i would rather a faster spooling turbo than something thats only good for peak power....

i know its a stupid question cos of all the variables but how fast would 200kw be in a fwd 4age? is there a genral rule of thumb to what 400m time it would do?

[Dell'Orto]

200kw is a shitload of power for a road car, people tend to lose sight of that with all these 300-400-500kw monsters you read about in magazines. It'll do 13's easily, maybe 12's if you can get it to hook up.

[Quirky]

My car is going in for a turbo mod at a performance garage aswell.
Ill be using an S15 Ball bearing turbo. Good choice?
Hope to get 150kw ATW, have been quoted $4000 for the job, including a microtech ecu

[escortman]

what times are u aiming for

i ran 13.8 on factory ecu, walbro pump, aries forged pistons 8.6:1 comp, bluetop head without tvis hooked up, no lsd, td05 16g turbo, was 7-10psi in 1st gear but had a bad leak that would drop boost to 5psi

[l1ttle_d3vil]

maybe 200kw - 250kw lol not much

not much??? that would be huge power for a street car.
im running 168kw atw in my ke25 (approx 200kw at the flywheel). granted it does only weigh 750kg (but does have pretty decent tyres on the rear) it has no problem at all skidding up in the dry without the clutch, in a straight line. just need to give it gas and it'll loose traction.

thats running a t25g on 12psi, not very laggy at all either. obviously a fwd car would handle alot differently from having more weight over the front wheels, but if I had much more power I wouldn't be able to use full throttle at all. i passed someone the other day at 100kmh, the time it took the speedo to go off the clock scared the shit out of me.

I've had a setup like that before, same turbo, standard fuel system and a Link ECU. That made 149kw's atw on 13psi with 8:1 compression.

$4k sounds like a VERY good price if its drive in drive out!

[Quirky]

Roughly $4000, Im going to give some headway to $5000 if need be.

The mechanic guy there said its a guaranteed 150kw at the wheels at 12psi of boost. Its good to know a similar setup makes the right amount of power. Hes also using the same setup on his AE86 race car, and recommended I use the same system as his.

Was at the drags on Saturday, and a RWD Corolla coupe with only 130kw at the wheels ran 13.8 sec on the quarter. My mate with a N13 Pulsar with 150kw ATW did 15.1. Front wheel drive is fail wheel drive? That said, our drag strip is very slippery, its just an old landing strip turned into a racetrack. Otherwise his car runs 12.8secs on a proper track.

$4k sounds like a VERY good price if its drive in drive out!

A good price or a bad job though?

You would need to check and make sure that the place is reputable first,


And I run 12.3 sec 1/4's on 205KW,
and thats too much power for a weekend road car really.
That was on a hybrid S15/GTiR T28 which would be too laggy for a street car.

IMO for a road car, T25,std T28, or maybe go for an early evo turbo ?

[Quirky]

Well I have the quote here in from of me.
Intercooler and piping = $800
Turbo and manifold = $1500
Ecu and tune $2000

The quote is a bit more detailed, but i just gave you the jist of it.
Sounds about right? Add another $300 for other bits like exhausts, mounts spark plugs etc...

hey mate you are asking a lot out of a 1600, with my new setup i am aiming for around the 250kw mark, the turbo ill be using has a HUGE compressor wheel, i have upgraded to race bearings, arp rod bolts and mains, better valve springs and brand new stem seals.

To make this sort of power and be realiable you are gonna spend around the 20k mark, you will need fuel system, computer, coils etc, a really good tuner.

That sort of power with a lsd gearbox and some semi slicks should be capable of low 12's with a fair ammount of seat time as well.

[Quirky]

200kw not much?

Id be happy if I could get at least 130kw ATW.
