RHD Single Turbo Bottom mount setup

[martymil]

Found a wiring bug which I fixed on the side of the road, almost up to 800 miles now.

Done some quick logs up to 4500rpm to see have the vanos is working properly and to check how things are doing.

Should be able to do a full log this weekend after the next oil change.

Keeping it on spring pressure for now, running motors in properly is like nails on the chalkboard bloody annoying.

In for updates - hopefully no news means good news

Bad o2 sensor or a faulty injector issue, Easter weekend so no work.

Plugging along slowly with engine mostly run in. Ripping hard on low boost with the cams.

Seems most issues have been in early tuning and crap Aussie fuel. V8 Bait keeps turning the boost and timing down so we can get our base 98 trouble shooting tune perfected.

My car broke the VTT double barrel bracket badly (likely install error - probably the only thing of others work we didn't double check) so Martymil has simplified the fuelling, back to stock location HPFP with PI when we need it. This is what we were chasing years ago but I wasn't prepared to have batch fire solutions. Now sequential PI on the table.

Dropped on some cheap alloys with the cars final wheel offsets and new Advan A052s. Super impressed with these tyres so far. Sticky and quiet.

Big change from my BBS CH-Rs. Rear 265s clear beautifully with the M3 v8 rear end.

Old rims

Fast forward we are still in lock down so progress has been stagnate.

Car has been sitting at my house and slowly making small improvements as we wait for the guruautowerkes HP28 kit to arrive so we can finally start winding up the boost, 5 year build time and stupid amount of money but we starting to see the light at the end of the tunnel.

This is going to break so hearts at roll racing when we can finally get there.

Marty has been mucking around a fair bit during lockdown stuffing in parts that have been around a while.

M4 Comp Seats go nicely and really hold you in all snug. Heating and memory all functioning perfectly thanks to Marty's wiring and programming.

1M Ohlins replace the BC ERs
New pads and rotors all round to go with the new M3 knuckles.

Nice one. I have the same brakes too

 

[martymil]

They are heavy compared to stock but they do stop extremely well

Who supplied the drexler?

Drexler Australia in Moss Vale NSW.
Speak with Herbert or email and his son, Eric will reply.

Great improvement over the M diff. Power down and control is brilliant.
Also gone back to a 3.45 ratio after trying 3.85 and 3.15s.
I suspect the 3.45 will just break into wheel spin once I turn it up.
Might have to go back to the 3.15
