So... in peoples own opinions, what would be the best engine for a TR/TS Magna (or KR/KS Verada):

1. 6G72 3.0 litre 12v SOHC NA

2. 6G72 3.0 litre 24v DOHC NA

3. 6G74 3.5 litre 24v DOHC NA

4. 6G72 3.0 litre 24v DOHC Twin Turbo

5. Other (if other, please post your alternative)

.

twin turbo has more potential as u just up the boost wen u want more power

personally I'll be sticking to 3L and non turbo, so the 6G72 DOHC 24 valve would be the ultimate upgrade. (What about the 6G72 DOHC mivec's? Would these fit?).

Insurance, I believe, allows engine swaps of the same capacity as standard (3L), and turbo would make the premiums much more $$ive. So the most power out of an NA shouldnt affect insurance at all, as far as I am aware.

If I didn't have to pay insurance then it would definately be the twin turbo. But since I do have to I'll say the 3.5l N/A. With a tt upgrade when I have a rating 1 :badgrin:

MIVEC VTEC etc in insurance terms is only alittle under turbo
mate has an integra was like 4G a yeah
only mate wanted a FTO same situation

i was thinking of puttin the 3.0 MIVEC engine (wen i start searching- wen im older), but after reading killbillys post in nicem8's thread (clicky) (http://www.aussiemagna.com/forums/showthread.php?p=254291#post254291) ive actually changed my mind to hav the DOHC 24v 6G74 3.5l V6 instead

I'm a rating 1 - so not a problem there (but I expect I may have to go to someone like Just Cars or Shannons if I upgrade/mod the engine. So premiums may change anyway. hmmm :doubt:

None of these. I would only use a Naturally Aspirated engine (just me, I dont like Turbo and all its lag).
So in this case, I would get a 6G72 3.0Litre DOHC MIVEC. :P

MIVEC wont fit as has been previously mentioned.

6G74 3.5l DOHC 24v is the goer if you can find one.

If not...6G72 3.0l DOHC 24v is the best bet if you want to stick to N/A

I have a feeling that the TT version is goign to be too much for the TR to handle

what was that? ... hope you didn't need that CV joint huh mate

LOL it's more like "What's all that smoke from?"

"Oh I just slipped on the accellerator...hey where's the nearest JAX?"

would the 6G74 3.5l DOHC 24v be an easy fit? (would it just bolt straight in, as easy as the 3L?)

From my searches I have the following kw stats - which are correct ?
- 6G72 3.0L DOHC 24V Twin Turbo = either 180kw, 206kw or 208kw
- 6G74 3.5L DOHC 24V N/A = either 162kw, 163kw or 198kw.

If the TT = 206kw and the N/A = 198kw why are we so worried about the TR handling the TT when we have no problem with it handling the N/A ??

Or am I missing something ? :redface:

Yeah there's different stats because there's actually two different types of DOHC 24v 6G72.
90-93 and 94+

90-93 had 202hp n/a and about 302hp TT, the 94+ had 220hp n/a and 320hp TT

My concern isnt the kW factor. It's the Torque.

The TT version has 427Nm of torque available form 1500-4500rpm! That's big block V8 territory available from almost as soon as you touch the pedal. That would be most difficult for a TR to handle, thats why my concern is. The N/A's only have about 330-350 or sometihng like that which isn't too dissimilar to a Ralliart (333-335Nm I think).

The TT would be a horror in the wet. I'm not saying it can't be done, I'm saying it'll need serious suspension work to make sure it sticks.

would the 6G74 3.5l DOHC 24v be an easy fit? (would it just bolt straight in, as easy as the 3L?)

Kim

Yep it'll be a bolt in im 99.999999% sure

I need to see Nicem8's in the flesh so I can confirm this though. Because I'll just compare his to mine. Mounts all look the same though. The block is just 18mm taller from what I've read.

What model did the 6G74 3.5L DOHC 24V come out in?
I know what you mean about the torque KillBilly if you were to tt then you'd definately want to put in a better clutch. Otherwise, a lot of smoke lol

Tommo/Killbilly, Would the RPM Clutch Killbilly & I have be enough ?

Also, while I'm typeing, Whatever engine I go for - what are the things to look for and to test/ask. If it's out of a car or in a half-cut - I doubt if I will be able to start it. So what do I do - how do I know it's a good engine? Compression test, etc. ???

The FWD DOHC 24v 6G74 3.5l came out in the Japanese Debonair.

Hmmm, just thought of another consideration - parts.

(Killbilly you may be able to help me out here with your DOHC experience... :bowdown: )

From the selection of engines in the poll, which ones have parts readily available in Aust. ?

Was the GTO (with the 3.0L DOHC or TT) ever sold in Aus. ?
...because I'm pretty sure the Debonair was not - so parts from a DOHC 3.5L (to fit a 2nd gen M) may be hard to get in Aus. :doubt:

its this reason i am staying with my original motor and spending $$ getting it more power..
once something breaks u'll have a nice hard time finding parts for it

Does anyone know if the quad cam head could be placed onto the 3.5l block. Then add supercharger and all wheel drive system and you have.

putting in an AWD system into a 2nd gen is something i would like to do, but i dont hav the cash or an engineers certificate to do such a thing, so its pretty much not worth it unless i am super rich and all that :doubt:

plus would anyone think an awd system would fit in a 2nd gen? sedan or wagon?

The 1st series GTO was available in australia locally.

The Jap Diamante F27A was awd/4ws (TR/TS shape)

cool! so its possible, but thats the sedan ay :confused:

Yep...no awd wagon AFAIK

It is possible but you would need to do a fair bit of work. I think you'd also need to change the rear suspension setup so that it's a mcpherson strut setup, I'd do that anyway so that I could put in coilovers :D .
In five years when I've finished my mechanical engineering degree I'll be able to write out my own engineers certificates as well. :badgrin:

what about dumpin a 3000GT in it?

A final post (I think) for those of you that may have been wondering what ever happened to my plans of an engine upgrade (DOHC or DOHC Twin Turbo).

Well in short - it ain't happening :cry: . Why? In short it's the cost thing.


I found DOHC Non-turbo engines - with and without ECUs etc.
I found DOHC Twin Turbo engine – from engine only, up to a complete GTO half cut.
I even found a DOHC 3.5L (that fits a 2nd Gen).

The warning signs started to ring when I started to add up the costs...
- DOHC TT half cut
- time/costs for mechanics
- time/costs for auto elecs (with the modified stock ECU or an aftermarket one)
- aftermarket exhaust/manifold mods.

But the problem doubled when I started looking at keeping the car legal. To keep the car ‘Road-Worthy’ which allows the car to be insured and sold, VicRoads required an engineers certificate. This is required for “Any engine not offered for sale in that vehicle by the manufacturer”.

I asked a few engineers certificate places and got mixed responses.
But most seemed to be pointing towards more costs
The response ranged from…
from….... totally no interested – or - make an appointment (initial interview = $200) and we can talk from there (WHAT!)
thru….... at least some tests, and the engineers certificate costs, (but even this was looking at $1000+)
right up to….... Engineers Certificate ($800), changing the complete braking system from the donor car (GTO) - including custom work to fit it to a Magna ($Big???), Emmisions testing ($3000 :shock: ), ECU testing($???), gearbox/diff replacement (and disabling of the 4wd diff to make it a 2wd) ($???), etc.... ???


Basically the costs were potentially escalating and very unpredictable. - oh yeah, and insurance was also going to cost more each year including a change of insurer.

Add to that, when discussing the engine swap with the only person I know who has swapped a DOHC TT into a Magna, he has lost his Heater - argh! that was the last straw - A heater is needed in ~shiver~ winter Ballarat. lol

Oh and don't forget the future possibility of wear'n'tear on other things like drive shafts, CVs, gearbox, clutch...

When sensibility crept back in :doubt: and I got my priorities straight and added up the known and potential costs - I could spend my many $$$ more wisely by selling the car and spending the whole lot on something else. In fact I could sell the Magna and actually buy a 3000GT or GTO with 4WD the DOHC TT already in it.

So my conclusion was to just keep the car and leave the engine moderately stock (nothing wild for me). When the engine finally goes – it will be rebuilt or replaced with another stock Aussie Magna engine.

Hmmm - oh well - it was a nice dream. I'll leave it to someone who can do the work themselves and who can do without a car while it's being done.

Hope I have not scared too many of you away - it'd be a great project :badgrin: - it IS possible, but the cost will be high and the car could be off the road for a good period of time.

i'm sure some of that is not right, doesn't the emissions testing mean you only have to pass the epa, fuel injection specialists can test this for you and probably fix for somewhere in the hundreds (stock gto should pass as in japan they have tighter restrictions), engineering certificates are expensive but they are probably used to get kids ringing up to put rb26dett's in their civics, you'd need the front cut definately...

when pulling out the engine from a magna and dare i say a gto it requires the gearbox to come with, i wouldn't dream of not using an lsd through the gto in a fwd and the brakes only have a problem with size of the wheels so i believe as the have huge ass quad spot calipers with huge like 15" disks??, custom manifold should go to far over 1K

i would never pay someone else to do it as your have to potential to get ripped off by 10k or so...i'm studying engineering to and hope to be able to have a few hooks ups in terms of certificates...

oh and i believe in japan the legal power output is 206kw or so which is what the evo is stated as having, i think the gto would have a little more and for legal reasons the manufacturers bull**** so i've been told, but im not sure the truth behind it

oh, bugger :(

Killbilly - did you need to get all your emissions testing, engineers certificates, etc. done?

Kim

i'm also unsure if it needs to be engineered, say you twin turbo a lancer does it need an engineers certificate?? killbilly doesn't need one as there was no change in displacement of the engine.

OH and GRDPuck how much were the offers for the front cut??

oh, bugger :(

Killbilly - did you need to get all your emissions testing, engineers certificates, etc. done?

Kim

No none at all.

The NSW regulations stated that as long as there is no more than 10% displacement increase and the original engine mounts are used then all you do is get a 1/2 blue slip which is just for a change in engine number.

Emissions testing wasnt necessary as I used the factory computer that the engine came out with.
