Since you're talking conversions...
How would a boxer engine squeeze in? 8)

Not so much a Rexxy 4 banger, but rather the 6 cyl from the liberty?
Massive amounts of torque, would sound absolutely killer wuth a free flowing exhaust and intake. ITs build would keep it low too.

Or maybe the V6 engines kicking about?
The suzi V6 will fit straight onto the sierra 5 speeds (with the divorced transfer case).

The Mitsubishi 6 cylinders also give big numbers from relatively unknown (and cheap) source.
Huh?

I figure this little adventure will cost me the best part of $10k if not more. I gave up keeping receipts a long time ago.


Man, I would have gone for the "Not displaying numberplate" option myself.

But by the sounds of things, the cop didn't give him a ticket for the illegal mods, but reported him to the EPA and gave them a heads up. :|

Ampz,
Not a fan of the Subaru boxers, Don't think they will fit between the chassis rails anyway and then there is the issue of a rwd gearbox that will bolt up. Same issue with the Mitsi V6's and the Suzi motor just doesn't have the aftermarket support.

Bevan,
Spot on, I did go the no plate option. The cop simply informed the epa that he believed my car was too loud, then you get the letter and it all turns to sh!t.

I must say I do like the V8 ideas but getting it legal would be a huge undertaking. Though I will be calling the engineer later to find out the feasibility of a V8.
At the moment it is looking more and more like a SR20det is the best bang for buck option. Will make the power I want with a factory ecu (or power FC), has huge aftermarket support so parts like forged pistons/rods etc are cheap, and has a great gearbox that will handle big power form the factory. Unfortuneately the 350z motor is still way too expensive and the headers would be a nightmare to fit in.
I will be developing a big brake upgrade as well, even though the engineer doesn't require it.

SR20det

Not 100% sure of the facts but I think it was Warwick Gates who won the WA leg of the Dutton Rally a couple of years ago in an SR20det kitted MX5. Then he sold it and it came second in last year's Qld Dutton.

By all reports a very sweet, very well sorted giant-killer of a car.

There's a mob in Perth that do SR20det conversion kits for MX5s too. Okibi should know them.

Is it really that hard to pass emision? My bro has a 1.5L ~125fwkw Mirage with a custom turbo setup with a full 3" exhuast
(including 6" tip on the "fart" canon muffler) and he was able to pass NSW emission an noise standards on his second try. I don't know why he even bothered to do up a mirage but at least it has some power and is road legal.

What ECU is he running? In NSW we are blessed, in that the emissions test doesnt cost us a cent, but in other states, they have to pay big $$$, whether they pass or fail. I can understand why he wants to do an SR20 - Isnt heavy like a V8, mounting kit readily available, huge aftermarket support etc. By putting in a V8, sure its got some power, but it just doesnt feel right

Can someone briefly explan why
1) it is more 'legal' to do an engine swap WITH modifications (sr20det) than to retain the currently turbo'd setup? I can understand an engine swap without mods can be more legal but if you are going to mod the swapped engine how does it make it any better... ??

Insurgence,
The SR20det will make around the same power(~160rwkw) with a good exhaust/front mount IC and some extra boost. With a bolt on turbo and a Power FC you can make an easy 200 - 220 rwkw. If you get an epa letter you put it back to low boost, plug the standard ecu in and change the exhaust and go get it cleared. As long as I run an airbox the front mount IC is legal. I have played with SR's a bit before too, we fitted one up to my brothers Datsun 1600 about 4 years ago now.

I have looked at the fitting kits available and will be doing a custom setup. The plan is to dry sump the engine in order to get the engine as low as possible. The engineer wants 20mm clearance all round so stretching the bonnet a bit may be required even with a dry sump.

As far as the V8's go, 4.0l is max NA engine capacity and that requires a lot more engineering. When I asked the engineer he started talking chassis torsional strength tests amongst other things and the costs associated. So it looks like the SR is out in front at the moment.

This is getting interesting.
Just a plonkers question. What would be the issue with getting a free NSW test done on a stock setup (ie: remove turbo, ECU, exhaust etc), and bring the results back down to Vic?

Does it have to be tested in Vic? Surely the equipment used is similar, or the same?

Jules,
They supply you with a list of approved testers. All are in Vic.

Apsilon,
Where did you get that price from on the 350z frontcut. EKW quoted me $7k if they could find one. At that price it is becomes a contender again.

I am planning the conversion for October. Biggest issue is it needs to be done between rounds of the MX5 vic club championship. I really don't want to miss a round.

SR20DET link. What a great engine. It even looks similar to the BP. 150kw. Easily and safely tunable to 250kw :shock: :shock:
