Ok cool.

I'm thinking, mine will be a road car, so with the flares, would the following work ok and sit well:

17x8 +15 front with 235/40/17
17x9 +15 rear 255 or 245/40/17

That would solve the strut issue without needing a spacer, though do you think the fitment would be ok with the big flares? It will poke out 12.7mm less than before. Thinking brake clearance would still be good!

What do you reckon?

Yeah that should work.
It will give you that extra grip.

[AusScare]

Yeah with my setup it is.

Ok great thanks. So the spacer is 100% required for the fronts?

Awesome. Looks like I will need big 17s and flares for my setup to get the power down and also fit big brakes. Where did you get these koyas from? I'm thinking 225/40 or 235/40 front and 245/40 rear semi slicks.

Did you end up having to run spacers on the front to avoid the strut?

I got them from Koyo in Brisbane - http://www.koya.com.au/
They are SF02's
I would recommend having a look at the federal 595 RSR semi Slicks, They are the best bang for your buck tyre. I also found them to be outstanding in the wet. I have run them on my daily 325i stroker without any dramas,
Also done plenty of track days with them and they have lasted pretty well.

I'm using A 10mm front spacer at the moment, but a 5mm spacer is better suited, I'll be reducing the spacer soon because I have heaps of clearance off the strut. I also just fitted my front IE Willwood 310mm 16" wheel kit. and there is a massive 2 inches clearance from the calliper to the wheel spokes. very sleek kit indeed.

You've put together a nice built engine but that log manifold is most likely causing the high intake temps from high back pressure.
A nice tubular manifold would be a huge improvement over that log.
Where's your timing at 13psi..?

Interesting! I'm still kicking myself for not getting a tubular manifold to begin with. my first intentions were to be a very low boost build but....
When will your manifolds be ready for the m20?
I Just put in a 600x300x76 cooler.
My tuner said he hadn't put much timing in it yet, so i'm not sure.

So slowly getting there, We have had boost spiking issues which is due to the wastegate being to small. so we are adding external gate and screamer pipe, which will be plumped back in after the downpipe.
Also intake temps were to high so I've had to add a much larger intercooler.
The car will be back on the dyno soon. will add photos soon.
Also we have the Race Pak dash sorted.
The car has had a rough tune on 12 psi making 300rwhp.

You could have this setup for the street, no problems at all. with the flares of course.
I love it.

Looking awesome!

How's clearance with that wheel/tyre combo front and rear? Is it ok for daily driving or just track?

Ill get some videos next week.
We are just having some issues configuring the Race Pak (Haltech) Dash to the Link computer. Hopefully it will be tuned next week.

any video of it running?? i wanna hear this thing..

Normally you would just join into the factory loom and use most of the factory wiring, if it were a road going car I would have got that done but we are only running the engine, brake lights and wipers.

So just splice the wires from the sensors into the ECU ones?
Still figuring out how I'm going to do mine. So much work to think about!
