I do just because there's one set up at work. :p...

I have always just muscled them on, or hit them with a dead blow. Removal sometimes requires a 2 arm puller, or if they are broken, pull the lollipop off and slice the steel insert.

As far...

Ignition timing is independent of the cam timing. The actual ignition event happens when the ECU grounds the coil, but the rotor has a large area as to keep the cam timing independent of ignition - so,...

Missed this sentence until Digger quoted you. That is EXACTLY how it should go. Reiterating above, the engine will tell you what it wants. The same thing happens when tuning, too. People often ask me...

One of the clients saw 4whp increase with retarding a 288 to -4°.

That's quite a blanket statement to say retarding the cam lowers performance when you have no data to make that judgement....

I know they flow more than enough to provide 100psi+ of pressure at 7200rpm when the springs are shimmed lol.

The vanos engines probably have more oil flow analysis done since they use the...

Was that compression number calculated with the 84mm stroke, or 75mm?

Personally, if it were that close, would have just notched the pistons a little deeper. The crowns are very thick....

One could just collaborate a bunch of scraped posts and compile into a book. :P

Cool! I wasn't sure John's build would end up here :)

[ForcedFirebird]

Good catch. I missed that in the read. Sounds like there may be a ground/power reversed....

Those two cars in that link were running on two different management systems (stock m1.3 and MS1 v3, single coil). I tuned them both the same day on the same dyno back to back.

If you have...

IMO, don't let it stop you from the swap. You can get to it from underneath. We actually only use the four 12mm bolts in the endurance cars for quick service (maybe not advisable for all). Actually had...

Check voltage coming out of relays with key on/off. White stripes on red is switched power.

Since no spark and no fuel, suspect CPS signal, bad/wrong relay, no DME power.

Easy/fast...

[ForcedFirebird]

^^^yup. Dead spot in the AFM, or compromised CPS signal/sensor would be my guess.

Since you were working on the head recently, check the CPS and wire. There's a plastic conduit that runs...

I have built a bunch of budget strokers in the years since this thread was posted (2.7 crank/rods, 2.5 pistons) and they put down 180whp with stock cams...

8500rpm redline b25 using VAC with 288 - three seasons, podium finishes, no problems.

Other car has Schrick, 7400rpm, HPDE/track 2014-2017, converted back to a street car and semi-daily...

M1.3 requires the blue temp sensor on the thermostat housing. If the PO forgot to swap it when changing the DME, then the readings are all wonky. If you have the blue sensor, verify the ohms, want to...

A quality stud remover is what decreased my head rebuilding times for 24v. Had three to do in a row one week, and started double-nutting them out. Decided to call the tool truck and see what he could...

[ForcedFirebird]

I have done literally thousands of m20 valve springs. I use a simple 12" c-clamp with a socket that has been notched and welded to the end.

Here's one that still floats around the shop...
