turboing my silvertop engine .HELLLLP!

[Bazda]

so many people who try do this 4agte conversion cheap, and what happens, the engine blows up, everytime!! cos budget is too low and they arent doing it right.

[crnkin]

yeah but had fun, got good power, and i hate sitting watching a car doing nothing while im saving trying to do it "properly".

After throwing 6k at my car, i wish i just left it bluetop turbo on 10psi, much easier, reliable, skidssss oh yea

[IH8TEC]

agree with bazda,

crnkin, alot of people that want to turbo their 4ag's, still want them to be reliable though, and sometimes you have to pay more for reliability.

[Lloyd]

Or not spend $5000 on a bodykit and wheels and then try to spend half of that on the engine

Or spend heaps on the engine and try to muck around with a factory ECu

[crnkin]

Oh i agree with doing it "properly"

If you have the means to do so.

With Snowbaording and Downhilling, even with sponsorship, I have fark all money to throw at my car, so i just do it, even tho i cant afford to do it "properly"

yeah I fully agree there, no point really going the turbo route if you are not putting ecu etc into your budget.

My sh*ta made 126 atw after doing conversion, a pitaful h/p gain from being supercharged really and it never will be worthwhile if your just going to limit its capabilitys with sh*t stock ecus.

I have since spent another 2.6k on a G3, pump bla bla, and still getting money together to get it in and happening. It would of been alot cheaper to buy a gtz already converted and tuned but wheres the fun in that?

I know my car needs a few things to make it a bit more nicer but its not a priority to me, getting the most out of my turbo is.

go before show definately

[Caveman]

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"

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

Sorry I did not mean it as an attack at you

Infact I respect a lot of the work you've done and your contribution to this forum, you appear to be one of the few 'get it done' people, which I think is cool and rarely seen on internet forums.

Because of the way I have been raised I cannot recommend cheap builds where jobs arnt done properly or shortcuts have been taken.

I do believe we have differences in attitudes to quality and presentation. I would not like to show off a 'rugged' build. Some people are and sometimes they turn out cool. I like my jobs to be quality. just my opinion, also not an attack!

I know what its like to be on a budget too Thats the beauty of new zealand, real know-how attitude to get stuff done on as little money as possible. Ofcourse dollars need to be spent but can be spent wisely and make the most of what you have bought.

Either way if you come up to auckland it would be very cool to meet you, would make for interesting converstation

[crnkin]

Im living here already come round to ellerslie if ya want, i just got my rona fired up! w00t!

Cars are the only thing i skimp on though, Im a marine designer and tend to do things ways that the engineers dont like, as i do them "properly" not easily

With my bikes too, if its not working perfect, im not winning, so i have to make them perfect, which is why they get the majority of my cash spent on them

you probly have my number, but its 021 307 515 anyways.

heh i cheated
i bought mine with a pretty fresh engine in and running a roadtune on a link. i also managed to get a good lsd gearbox already setup too. there was a lot of things i did have to tidy up tho , and i bought the car aware of what was required.

the engine turned out to be a strong build tho and hasnt given me any major issues itself. guess i got lucky there as you cant always rely on other peoples work. i also got the bonus of a chassis and driveline that was setup well as the car had seen a lot of the track before.

i had all the bits from the start but it wasnt until I threw a lot of my time+money into it that the results start showing what it was capable of. my power has climbed from 145-172-182-218kw atw.
thats all with the same core engine/turbo setup, and making it more efficient along the way.
im guess im one of those people that doesnt really like to see something done halfassed, if i was id probly be pottering around with my original power output. i cant stand the idea of wasting power that you could otherwise be using, by use of crap manifolds, tired old turbos and half assed ecu's etc.

[IH8TEC]

pfft, my std ecu goes hard. but i think i have reached it's limits, nad it has proved very good, probably becuase it's the afm one and not map sensored. but as limits have been reached, i'm now upgrading, although i would not say my car has been half assed at all. i dont think anyway

[Infinite]

i have a 20v silver top levin with a MINES ecu in it would that be anyuse if turbo'd? its non programable or anyone know what they improve narh im not thinking of making a 4agte lol mite drop my 3sgte into my levin tho cause its setup way better just needs a bit of bodywork :/

[thaphatty]

runs like a racial minority with a stereo...

thats $&#$% crack up

No, it's set up for NA, and will have massively advanced timing over stock, definately not what you need with boost.

[antonio]

Ive heard from friends of people turboing 4afe's and silvertop 4ages, and didn't even muck around with the ecu's, but done some other mods but not sure of what had been done, and ran it around 4 to 8 pound boost and it ran sweet.
Has anyone know of people doing this. I was thinking about doing it to my 4afefor fun and run it low like 5 pound, see what happens, only cause im dropping a worked silvertop in it latter. What use think will it last or my mates
talking poohaa!

[bluemaumau]

do it

[matt dunn]

Anyone know what CR you get out of an 8.9 bottom end with standard Silvertop head on btw?

Not really what the CR is,
but my setup like that takes 18psi fine.

You can put an adjustable rising rate fuel pressure regulator in it, that'll do the fuelling side of things.

Some people put a check valve or a couple of check valves (set it up correctly) in the MAP sensor line, to stop it fuel cutting when it sees boost. Some people just put the car into diagnostic mode and run like that.

Pull the stock timing back to between 0 and 5 degrees BTDC and go.

Be careful though, as it's a pretty risky setup if you're not going to keep the boost low and check for knocking and checking the A/F ratios.


Have a go and see how it goes, as you say, if it blows, you've got another engine to go in it and you don't seem too bothered.

[dash]

yep,
there are literally thousands of turbo conversions this side of the pond rippin it up using rising rate FPRs.
Vortec 12:1 FMU (fuel) and MSD BTM (timing retard) are the most popular components, ~$150-170 each new, half that if used. Both remain transparent until boost. Some of these street cars have 12 second ET & last years.
A piggyback is the next step up for finer tuning. A SAFC fuel tuner perhaps the single most popular device sold. The $300 Greddy emanage has proven itself in the competent DIYer hands also.
Spending lots of money is optional.

That's right dash. My research has been beased on that kind of set up. It's very popular in the states, but not realy used in NZ.
I'm going for an FMU and currently looking to get an MSD BTM, however they are a bit more exspensive than that here. I'm guessing you're in the USA? We don't have many MSD delaers here and they're around $450-$470 new and very very difficult to find second hand.

I'm not going for a 12 sec beast, but just something that will drive like the stock car, until boost comes on and then the FMU and BTM takes over.
