What needs to be done to cert a subframe like this?

Bellhousing would work with an L3 engine too? 

L3 LF L5 and the 1.8 version as well as Duratec 4 pots in 2.0 and 2.3

Um is there pictures or more details of this somewhere ? 

Not really but its pretty simple,

On the bottom of pic is an NC 5 Speed

And here is a pic of an NA 5 speed

Swap the front halfs over

What gearbox have you got behind the new engine?

NC front housing off the NC 5 speed bolted up to a NA 5 speed box

Did some more drivving, neeed to change a couple setup things then it should be better

what engine is that? LF?

Yeah LF-VE but I havent got the VVT going yet. I think this one was out of a Mazda 6 or Premacy around 06 model

1. So good man! That new engine will be a force with the VVT. How does it feel compared to old?

Yeah should be decent, it pulls hard and smooth but doesnt feel punchy like the 1.6. mid range is a bit flat but heaps of torque. Weight drop is about 40kg over the whole car so nearly sub 900kg and the front being lighter makes it a bit more understeery but the lack of front cambe makes the steering heavy

That was a decent hit on the hillclimb!

I've done similar in the past - mucked up the corner before, thought I'd saved it, threw it down a bank almost instantly. 

Glad to see there wasn't too much damage .

Haha yeah was a bit of a dull moment on my part but fairly easy fix and I drove it home as well as did another run that day

That was a pretty big hit on the hill climb. What was the damage? New engine build looks awesome, looking forward to seeing some vids of it sliding.

Just a broken wheel, couple dents and a bent shock not too bad.

Have been super lazy with up dates but got her all running, tuned and Certed.

Heres dyno graph, sadly no VVT and the exhaust I made is pretty rubbish.

Vid of it drifting for the first time

So bit of work to do as I snapped the clutch slave, the alignment needs changing and I need to drive better. But slowly getting there

Any forseable issues before I get a pro round to weld them in?

Yes, they supply gussets to weld on for support on the plate side

Was it just me that thought 6mm was the go?

I couldnt find anything in here, https://www.lvvta.org.nz/documents/standards/LVVTA_STD_Engine_&_Drive-train_Conversions.pdf

Maybe its in the Hobby car manual thing?

3mm Steel

Moar questions 

Couldnt find anything about the angle of a mount, just the rules saying the mounts have to be able to withstand all forces exerted etc.

Because the Mazda box tilts the motor 11deg the right side mount will come from a higher point than the left side. Basically left side is parallel with ground and right side is pointing down to the motor. As long as they are strong enough this is no issue?

Would I need to supply drawings if I was going to weld brackets like this for the engine mounts? 

It has no effect on any suspension geometry but just wondering if it would need anything more than to be well constructed for cert

At pick a part Mangere, some please save

Depends. If it's got the suspension pick up points on it then it needs design approval. 

If it's just a subframe that mounts the engine then no approval necessary.

Yes would need cert.

So MX5 would defo need one, is approval easy thing to do with pictures or mock up photos/drawings?

If I brought this to the meet would anyone want to trade a burger for it?

Whats the dealio with tube subframes or welding new engine mount pick ups to stock subframe?

Does it need to be approved or crack tested? Or is it more as long as it looks strong etc its fine?

And at the flywheel

So I havent updated in quite a while, been fairly busy.

So heres a quick run down.
Smashed a door at Hampton
Crashed into a bank at a hill climb - 

Smashed another door after a drunk lady hit my car while it was parked and I was trying to get in it.
Went to Dunedin and just missed out on qualifying
Pulled my engine out and made a new bottom end

 

So right now the engine is finished, run in and tuned.

Heres the results which Im quite happy with, and thats at the wheels

Ive missed out the past few meets so should make this one hopefully

Wicked idea, cant wait to see how it goes

Thanks for the push guys
