turboing my silvertop engine .HELLLLP!

[antonio]

So is that All i need bro is pistons rods and a upgraded ecu?

[flygt4]

no.kind of. not really.sort of.

[antonio]

So do u really need to do the ecu upgrade and link can I go around it,
Im only looking to run it at 9 to 10 pound boost.

[flygt4]

you cannot run vvt and positive boost pressure on any standard ecu available for 4age.(that i know of)

you can run a 16valve 4agze with either standard map or afm 4agze ecu's , but there are differences n their effectiveness i dont know enough to comment on.

[Crampy]

There is a guy on here (trueno_20v) running a stock 20 Valve Silvertop with a TDO5H and a link ECU. Had it tuned at 5psi and had something like 133kw's ATW.
Not bad for the completely stock bottom end. Still to get the turbo fabrication and ECU install/tune and everything is gonna cost ya more than $3000 I'd say.

It would be a damn fun car to drive, I'm sure of it.

[Crampy]

A good turbo manifold alone will cost you about $450. Action_Dan and evil_si do them for around that and they are damn good!!!

[Crampy]

You could get an adjustable rising rate FPR and bump the timing back to 5 or so degrees and run it on low boost.

Not sure how long it would last (read: probably not too long) , but at least it would be a lot cheaper than getting another ECU.

Anyways, that's what I'm doing with my AE92 FXGT, but it's a 16 Valve $hitter, so who cares if it blows?
I even got a FMIC on tardme for $32

[crnkin]

tsk tsk tsk.

Yet another 4age turbo.

step one: Save money

Step two: buy a 4agze bare block (500-600). swap everything from the silver top over, with new head gasket (100).

Step three: Buy turbo (100) intercooler (100) log manifold (250/shuddup) oil lines (100) piping and hoses for intercooler (200). Then install it all in the car

Step four: Buy a link ecu, get it wired in (2000 for a new one, 1250ish for a v3 ish)

All up i guess best case scenario $2600 plus sorting out shiit bits and the inlet manifold so 3g basically.

Thats doing ALL the work yourself. will net around 190kw atw at 18psi

Or option 2, bluetop turbo stock, for around $500, netting 120kw atw at 7psi

start saving and researching, with less questions, aye crampy

[Crampy]

My project is getting along very slowly crnkin, but I have been a bit lazy with it. It didn't help I had to move to a new house and work's been busy, etc etc.
All excuses I know, but I'm hoping to have my 4AGTE project done this year!!!

Anyways, there's nothing wrong with asking questions, that's what a forum is for.
BUT, it also helps to search first (research) and then ask more informed and specific questions, rather than just asking how to do everything.

[Caveman]

YOU NEED

turbo manifold
turbo
dump pipe
exhaust system
intercooler pipe
intercooler
pod filter
BOV
new plenum for 20V
intercooler joiners, reducers, bends
probably need an oil filter relocator
boost gauge
ecu + tune
air fuel gauge
stronger clutch
sticky front tyres
optional rebuilt bottom end

you cant do all that for $3000

ecu + tune is $1500, half your budget gone, engine rebuild would be atleast a grand. hot damn what happened to $2500

Its entirely possible, just budget for $5000

go hard

Sell yah GT Appex, buy a GTZ

Turbo that

[crnkin]

Sell yah GT Appex, buy a GTZ

Turbo that

seconded.

you dont "need" things like better clutch, BOV, intercooler, dump pipe (just weld on old exhaust), exhaust system, pod filter, oil filter relocation, air fuel guage, wtf, sticky front tyres?. But all bar two of them would help.

its always a case of do what you can afford, my car has cost about 8k including mags, adjustables, and the car itself doing all of the work by myself, the only thing i payed for was my exhaust.

When i started out i said id do it on 2k in parts! (i then upgraded alot of things).

Buy a gtz, and start saving

ok you probably dont need all of it

but im a big fan of do it once, do it properly and do it right.

none of this half arsed bullshit.

but I agree, going gtz then turbo is a good and proven path.

[crnkin]

dont you have a turbo redtop high comp?

[Caveman]

dont you have a turbo redtop high comp?

yep

but because ive researched and done everything properly I drive it to pukekohe, trash it for the day, then drive it home. Same applies to rallys, autocross, etc

Good bearings, good ring seal, good cooling, good fuel, cool intake temps, free exhaust, correct timing, regular oil changes.

With higher static compression you need to run lower boost. All you are doing when boosting the engine is increasing the compression ratio. Add the two together you get your final 'bang' magnitude. I must admit its a little more complex than this but im a little tired right now lol

I'd just like to say 1998's smallport runs like a racial minority with a stereo... Had to see it to believe but man! awesome car...

[crnkin]

yeah not attacking or anything. But to make sweeping generalisations like not running a free flowing exhaust or, using forged pistons, or using a log manifold, are to say the least "sweeping generalisations", and fit the purpose and the time and place perfectly, and to infact say that doing anything but is half arsed, is a) hipocritical, and b) wrong.

(just opinion, not an attack!)

I mean, for a start, you researched and done everything "properly" (which is good!, saves you and me time), and probably took the high compression route as something someone in "the know" suggested to you, and you researched further, then proceeded?

Did you know there was a stock 4age smallport high comp running 15psi on a t3/4 with 210kw atw 3 years ago?

It was done half arsed, it was on trademe, and it was cheap. It also produced awesome power.

Not saying that "half arsed" as you put it, or "doing the trick" as 50% of the other population would, is better than doing it with lots of time, thought, planning and MONEY, but I am however acknowledging that it is one way of doing it.

I bet we could both throw 5g at a 4age, and come out with completely different characteristics, with you spending the money all around, and me spending it on what I deem to be important, and youd like it, and id like yours.

So, please reconsider "half assed bullshiit" more of like "Hutt stylez/crnkin stylez with power on a budget, with all work done by the owner, and learning along the way, having fun"

Cher

Big post, but just got back from town and the girlfriend still aint back

[Lloyd]

If its on a budget then there is nothing wrong with a log manifold, non free flowing exhaust etc. People build stuff to their budget, sure it may not be pretty and might not be the absolute best way to do things to et the most power and response but that comes down to how much you want to spend on it.

That turbo 5K I had in the Starlet was with a cheap turbo, the "plenum" was the twin carb air filter housing welded up not to leak, fairly standard internals, exhaust manifold was standard with a bit of pipe going down and looping back to the turbo, muffler wasn't even straight through. The thing went bloody well and happily ran up to 19psi through it.

There is no point at thorwing heaps of money at something if you dont have it to get that extra 10hp out of it or whatever




Someone take me for a ride in a high comp turbo 4AGE please
Anyone know what CR you get out of an 8.9 bottom end with standard Silvertop head on btw?

[Chickenman]

But haven't I seen you referred to as Mr Bang or something similar?

[crnkin]

dunno about "mr" bang, but ive been known to test the limits of what i build, yes.

13psi on 4age bluetops, bout as far as you can go. (20psi - too high )
