Nor can I see the pic.

yeah i noticed that all the old links to the old build is gone.

All the current photos are uploaded to google and not imageshack so these should stay

some minor update:

Waiting for some parts to arrive so I cleaned up the water neck



I've been advised not to reuse the oil cooler because the metal bits might still be inside and is next to impossible to clean it out. Does anyone know where I can source a good one? I'm hoping not to rebuild it again haha

[— kung fu jesus —]

I can't help with the oil cooler, but was there any evidence that described how the rod bearing spun? Which piston rod spun? Just curious.

I remember (vaguely) some racers in the early '00s with FWD BP-powered racecars, like Escort GTs, Protege LXs, etc., would chamfer the oil passages on the crankshaft because of oil starvation issues at higher RPMs or lateral G loads. It's been a long time since I discussed that but I seem to recall the pump was cavitating? The only Miata-related oil pressure change I have discussed with racers was a dip under hard braking. I installed a static baffle in my sump when I rebuilt my engine this year for some protection.

As for forged internals, I have the same opinion. The stock pieces work quite well unless you are running higher than stock RPMs or power levels. Even then, the times I ran F/I, I didn't have issues in the stock engine. This lump was designed for F/I. It made little sense to me to add super-duper internals on an engine that sees more street use than track.

For less than the price of forged parts alone, you can be build a very nice hopped up engine on stock internals.

I got a replacement oil cooler so that should solve the problem.

If I remember correctly the engine builder said bearing damage on cylinder 1 and 4.

finally time to work on it. I had a crazy summer that I had to work every single day till now.

Engine being put together. Will update more soon

I know I haven't been keeping this thread updated. The truth is, there's so much going on in my life for the past year that I put the miata at a pretty low priority. However, there's going to be some new updates soon.

The car is currently up and running, and it's going through the break in process with the new motor right now.

fixed. It's nothing crazy. Will get more photos soon!

[rikaro]

Finally able to get some pics of the car. Excuse the gauge hood cause I cracked it while installing the revilimiter gauges

[Slampen]

Nice car.

I can only see the first picture in the post above.

I've been away for more than half a year but I just wanted to come update you guys with the miata. I still have the car and I have been driving it daily now for the past few months. I'm slowly cleaning things up after the swap.

Restored a momo indy steering wheel over the winter but didn't get to keep it on the car. I still prefer a softer leather wheel





Also replaced my old strap with a leather one. One of my favorite pieces on the car right now.



OLD


NEW




This is probably one of my favorite upgrades on the car. Lotus elise seats with Ryokrob seat rails. Pre-probax isn't as comfortable as the probax one (I have sat in both for long distances) but the seat i got has lumbar support. Top upgrade as I always feel cramped inside a miata so this is a game changer.



Did a track day in July at the Ridge Motorsports Park. If you've followed my thread, I've been going to the same track at around 2013, but the motor died on me so it was parked for a bit (and rebuilt twice. story of my life.) I went back this and was hoping to beat my previous record, which shouldn't be a problem because I have more power now. However, a certain area of the track has been repaved so it runs a new configuration. Most cars are generally 1 second slower than their previous layout. I ran the same 2:04 flat on a really hot day so it's promising that I could get it down to the 2:01s. The VVT engine also requires dyno tune so i can get the most out of it. I was running at the same pace as a 01-05 vvt miata on the straight. I'm now running re71s instead of ra1

Also got some new wheels recently. TE37V 15x8 +25 SL. 4 lbs savings per wheel compared to the drags dr54. I missed the look of the old wheels though





The car currently develops an oil leak from the front. I suspect it's from the front crank seal. I'm am crossing fingers hoping that it's not the BE pump as they previously sent me a size that the front crank pulley wouldn't even go on. Otherwise I believe my engine builder didn't install it properly. It was fine for the first 2000 miles of breaking in but starting to leak when I drove the car down to the track track on a hot day. Now it was leaks whenever i park. Otherwise the car is pretty reliable.

I hope that sums up what happened in the past few months. Not a lot but I'm glad I get to drive the car again.

You could eat off of that engine bay!!

i like cleaning hahaha

Unfortunately it may be the Boundary oil seal; they have been reports of them using cheap Chinese seals for some reason, which is weird to me. In any case, it should be a straightforward job replacing the seal, although a bit tedious as it requires the timing belt to be removed. I would monitor it and go from there.
