Engineering!

[greenmac80]

Hey all!

i did a search on engineering but it didn't give me anything that i'm really after!

 

does anyoone know exactly what engineers look at when you've done an engine conversions?

all i know is that everything has been made properly and that brakes are upgraded to suit!

 

anything else?

 

also anyone in adelaide had engineering? how much is the question!

i want my car to be legal!

 

any info would be much appreciated....

or even a link with the correct info!

all found using the search string "Engineering" using the rollaclub search (And some are even directly SA related!), Please try harder in future..

[greenmac80]

I found that first link and read it through!

didn't really give me what i was after!

see i have some chassis rust and i'm worried that unless i get it welded up then they won't register it!

i'm doing everything else properly though!

upgrading brakes and profeesional mounts etc!

[love ke70]

ring your RTA.

ask for list of engineers

talk to engineer

all will be well once u get an engineer on side :S

[spittao@yahoo.com.au]

may i sugest cutting out the old rusty bits as you might know, pressure clean the f@$k out of it and spray the whole thing in that spray tarry stuff, if they do check it what would be the chance of hitting one of the newly welded up bits lol. your from adelaid right, is the car defected or somethin? or is this a first time through moto rego dick people place at beach road lol.

Talk to John at SA Chassis & Suspension in Brompton.

 

He's a Regency approved chassis repairer and welded up both rails and plated them on my 25 for $660 (that also included plating up the massive hole in the bodywork under the battery tray I had).

If I remeber correctly your putting a 4AGE into a KE30 / 55. Pretty sure they won't like it.

 

Tips would be: - Brakes upgraded, but try to keep standard.

- All new bushes

- Keep engine standard. All emisions, no sport exhaust.

- Make sure you don't have rust in the shell . . . they don't like that to much at all.

- Try to keep the interior standard unless advised by an engineer.

- Have reciepts for all custom manifolds or mounts. Have proof of professional workmanship

- See with engineer about upgrades to handling . . ie thicker swaybars or strutbraces.

- I think they like stock ECU's a little more than aftermarket, at least I have heard from a couple of accounts it can be easier to get through with one.

 

Its not going to be easy, but you may have a chance. Maybe the guy in SA whose doing a KE70 4AGE through Regncy may be able to help you :)

 

Cheers Fusion (sorry if its a little blurry . . a little sleepy)

 

PS: Cheers Raven . . . so checking him out one day :S

Yeah, i can help you out if you're doing a ke70 with 4age as i've basically got Regency to allow it to be done without engineering ( :S ), but if its going into a KE30/55 i think you're gonna have a few more issues. Unless you can find a ke30/55 that came out ANYWHERE with a more powerful engine thats within 20% of what you're upgrading to (ie your new motor can have 20% more power without being engineered). Give the modifications branch of regency a call and have a chat - i've called them a few times and they were REALLY helpful.

 

THe way i went about mine was to fill in an application to modify a motor vehicle and put a covering letter with it clearly explaining what i was planning (already done) to the car, and pointing out how everything i'd done was a BOLT IN job with little/no modification. I think the trick is not to sound like a young punk who wants to have the most powerful car on the road, instead, someone who's done their research and taking the steps to make the car safe. First step would be to fill out one of those forms, then Transport SA will send you out a "statement of requirements - vehicle modification" detailing everything they'd want done. I have a feeling it'll involve engineering though, which would be between $1500-$2000 from my research :)

[philbey]

I've also talked to the guys at Regency, and yeh, they were really helpful.

 

The last car I had engineered in Victoria was also simple like turbo_rollas because it was bolt in parts, so nothing too in depth.

 

Not sure if this applies for SA, but it needed a brake upgrade to match the new power, and this required a brake test. 10 stops from speed, cold brakes. The pedal pressure was measured and the braking G forces. Across all 10 stops, these 2 figures had to be within a tolerance band, hence metal compounds are no good as the test was with cold brakes.

 

As for emissions, you should only have to meet the requirements for the year the car was built, so if you keep factory emissions on a motor which is newer you should be fine there.

 

As an engineer (but not the sort that can do a car report..... yet) myself I would suggest that anything you cut and weld is the first thing you would have to worry about. For example, cutting and shutting crossmembers or engine mounts etc. If I was going to approve these mods, I'd want to see

 

- a comparison between the standard and modified parts

- Sketches, drawings, CAD models etc. More so to show you've thought about how and what you need to do, not "cut first think about later"

- details of any extra material/gusseting/strengthening added with the modification

- Xray report on the welds if they were really critical, or at least use a qualified welder to do the work so the engineer knows they will be kosher

- even just seeing the part out of the car, unpainted would be very handy for any engineer.

 

If you are designing the mods yourself, it would be good to ask the engineer what is the best way to do it and how to make it strong etc. Even to the point of getting him to design any really difficult stuff etc.

 

You could do the chassis mods yourself and hide them, but if you are genuinely worried about integrity, get the engineer to advise on this as well. I'd take Ravens route, and pay a good chassis shop to do the work though.

 

My last car was done in Vic by a VACC "engineer" who was a mechanic with some extra knowledge. In SA though they are all done by a Chartered Professional Engineer. They will probably ask you tough questions and tend to pick on you for what seem to be small items. I would suggest you go over the whole car and change every bush, wheel cylinder, brake hose, tie rod etc. You have to realise that once an engineer signs off that document, he opens himself up to liability if your modified drag link fails and you kill someone. Hence, he will want to be certain the WHOLE car is safe, roadworthy and built to a good standard, not just the 2 or 3 little bits you had to cut and shut to get the new motor in.

 

Here is the list of DTEI recognised engineers , call them and start talking. I'm also under the impression that any CP Eng can do these reports as long as they have experience relevant to the mods.

 

Good luck with it, and keep us informed!

 

Cheers

Thanks sooo much!

Well i shouldn't have too much problems then!

i have got all new bushings am buying new lines..

i have completely rebuilt my cressida struts..

the t series diff i'm buying is completely rebuilt!

basically everything is getting done properly!

except the drawings!!

i'm getting other people to do the welding.

a proper performance shop!

so maybe i shouldn't stress sooo much!

all money and time!

[philbey]

With drawings, I wouldnt stress too much, but it would be handy for any engineer to look at and understand what you've done and how, rather than trying to jam his head into tight spots with poor illumination etc.

 

Take lots of photos as you go along as well.

 

Good luck with it.

I've got a mate a regency,

 

they are not to fussy as long as you:

 

go to regency on your own free will (not defected)

 

your brakes and suspension have been upgraded to suit

 

its not rough (looks neat, ect)

 

it wont burn (all wires, fuel lines, ect are far enough from hot parts)

 

and your gearbox/diff will be able to handle it.

 

if you are interested i can get you all the info you need.

send me a message for more info

 

cheers Jarrod.

[kangaroosa]

I'm dealing with an engineer for my conversion at the moment.

The main things he wants to check upon the conversions completion are:

- Crack testing of the Corona Stub axles used in the brake upgrade

-All welds to meet his reccomendations (3mm Mild Steel for engine mounts - No greater than 1.5mm wide Welds - DEFINATELY NOT ANY WELDS ACROSS THE CHASSIS RAILS!!) He emphasised that. Apparently its induces cracking......so the only welds on chassis rails are to be along the length.

- Brake test

- <96db at 3/4 of the max rpm

The rest is pretty much straight forward and should be part of your roadworthy requirements anyway.

 

Any fabrication work (mounts, diif, cages etc) need reciepts to prove the fabrication and welding was done by a pro.

In vic be prepared to shell out $1000 for the final Certificate if you have changed the engine, gearbox, diff, brakes and wheels.

[Fat Bastard Customs]

the street machine magazine website also has a list of all the registered automotive engineers in each stae, with ph. nos. and locations.

[SamboRA65]

Do you guys know if you would pass a RA65 celica though with a 4AGE in it? with out to many mods?

 

Sorry if this is a "noob" question but I would really like some answers ;)

 

I'm in Adelaide by the way if that helps? might be different rules for different states (not to sure.)
