Turboing 4age Red Top

[DXROLLA]

Im wanting to do a basic but reliable turbo build not looking for massive power if i made 200hp at the wheels id be stocked any more would be a bonus.
I really have no idea where to start. The motor i have is a red top with tvis.
It will be getting re-built but with what i am unsure, could i use gze pistons to lower compression and would they be stronger? Would i need better bearings or should the factory toyota ones be fine? Conrods, should the standard red top ones be suitible or should i look at going gze ones aswell or are the basiclly the same? For the head should a basic clean up be enough? Valve grind, stem seals ect?

Now for what turbo i should use. Im wanting the engine to have good mid-range and not to laggy but if there is no way around that than i gues i will just have to live with it. The motor will be mainly used for sealed hill climbs and track days.

Computer, will the factory one be ok maybe get it chipped or should i just go aftermarket?

Cant think of anything else i need to know at the moment but if you have any ideas let me know. I want to use the engine i have.

Try the search function to find one of the many topics about this. There is LOTS of info.

But to answer you're questions:
- Redtop TVIS is likely to have the smaller early rods and bigends (some people say they do, others say they don't)
- You could use a standard 4age computer in diagnostics mode to get a bit more fuel but you wouldn't get 200hp with standard injectors.
- Go aftermarket ECU
- Use T25, T28, VF10 or small trim TD05 for decent spool.
- Use 4agze 365cc injectors (they will stretch to your 150kw/200hp atw goal)
- redtop tvis compression is only 9.4:1 or somewhere around there so will be fine with standard pistons if tuned right.
- Can't remember if 4agze pistons will fit early rods but are stronger..

Go for gold.

Cheers for the help, i had used the search function but couldnt find anything specific to what i was after.

So a standard re-build should be suitible and will handle the power i am looking for? Just need a good tune and some injectors?

It'll make the power no problem but the weak link with probably be the standard pistons, especially if you are going to be using it for hillclimbs.

If I were you I would look into whether the 4agze pistons will fit the early rods, if you are lucky you may have the later rods which means they are the same a the 4agze anyway.

Try searching for info on the difference types of conrods, that will give you some info on what you have.

Also have a look in the projects sections at various 4agte builds ie Mine, IH8TEC, Bazda (old one), Little Devil, gasman, NOLAW, Flygt4, Caveman (old one), 4agtepwr, bluemaumau, escortman etc etc.

Pleeeenty of info.

the rods will be fine.
its the bluetops that have the smaller CRANK JOURNALS (40mm vs42mm) the bluetop rods them selves are big and chunky.
you will have the biggest rods fitted to the 4ages and they are exactly the same as the first 4agzes.
same with the bearings.
and 4agze pistons are fine
200hp is easy on those parts. not a lot at all.

Sweet cheers for that so the ze pistons will be fine to go on my rods 20mm red top ones?

Phwoar look at the size of those fu-ckers!

Yep.

[escortman]

yep go ze pistons, id recomend the 8.9:1 pistons

talk to mark theres the prices

most people run acl race series bearings, cheap and work well

for head i got a full freshen up with bluetop cams, kelford cams stiffer valves springs and some flash titanium valves cant remember the reason for them now but yeh

like slideways said can run factory ecu in diag mode but best to get aftermarket ecu

turbowise any slideways said will be perfect, if your really wanting no lag something like td04 maybe

[l1ttle_d3vil]

my t25g on 5psi with link g3 is making around 170hp atw, thats on a bigport redtop 4agze with 8.0:1 compression. you obviously wouldn't get that power on stock ecu in diag mode. to get 200hp atw on the cheap you'll be struggling i think.

to do it reliably you'd need ze setup + aftermarket ecu. you could pick them up for cheapish though, especially if you got an older model link and had it configured to your engine. otherwise latest links are $1200 then you got install + tune ontop of that.

Sweet, am going to have a look around town tomorrow get some prices. Im not doing it on the cheap i dont mind spending the money im just not after massive power. I got priced from hpe in chch for around the 3g mark for full recon using forged pistons which i didnt think was to bad.

[Mr Revhead]

just remember that 4agze pistons are forged and well up to 200hp

[DXROLLA]

Yeah those prices do look very good, mite get me a set of them. Do you think itl be worth using some ARP bolts maybe head studs atleast?

Whats the main advantage over the 8.9:1 piston to the 8.0:1? Im guesing you could make more power with the 8.9:1 with the slightly higher compresion? Would that effect how much boost you could run?

yeh ze pistons will handle 200hp easy, i only ran arp rod bolts but all up to you and how much you want to spend

with higher compression you make more/same power on same/less boost
better of boost response, IH8TEC is now running the higher comp pistons in his setup 20+psi

Ah, make that 450hp as they are the same pistons I run.

[gleem]

whats the most hp you can make on a stock ae101 ze bottom end for reliability?

What is you definition of reliability?

It comes down to how hard you drive it, how well you service it, how good the tune was, how good your fuel is, whether the engine was rebuilt or on its last legs, what parts you use, blah blah blah.

You could make 250kw's and have it last 20 years if you only drive it to the movies on the weekend.

Or you could make 120kw's and blow it up first track day due to a million reasons.

how much power can a 4agze handle without stressing??
