tii engine rebuild and 5 speed swap

Definately not too soon, Steve.  Been scoping out a couple of places for the scrape and paint. Once I can get NYNick to do some work on the suspension ?, it’s Re-Ceylon-ification time!
 

 

Nick’s Polaris hot-rod was black when he bought it, Vince. He returned it to the original Polaris. So he might have a few thoughts on the issue of re-painting as well... ?

 

Best regards,

 

Steve

My routine of driving the car onto the trailer, driving it to pit lane, one pace lap, and then go like hell just did not seem like the right advice.

Paul,  your ‘Break-in’ technique sounds pretty tempting. Holding off on going like hell for 500 or more miles is going to be tortuous. 
 

I mean, I’ve just volunteered to get essential groceries for the next couple of months for my household.

Nice work Vince.

Really good choice on pistons and cr.

Street tii cams .360-.380"gross lift 284 duration (Schrick, Schnieder) work really well.

Along with the compression bump the mild cam will give her some balls.

Someone correct me but i was taught years ago that to break in the motor you do in fact go like hell, within reason. You want big explosions in the cylinders to pressurize the piston rings, that the high pressure wants to expand the circumference of the ring increasing its pressure against the cylinder walls helping seat the rings.

Back in 2009 when I redid lots of things to my tii (including new piston rings and rod bearings), I received some good advice from Rob Torres (2002Haus).  He told me it was important to vary the load and rpm of the engine during break in.  Keep the revs below 4500 for a little while and use engine braking occasionally to slow down (to vary the load).  So far, so good.

Always good advice. And M10s are almost completely bulletproof even when run at red line.

 

Which is a good idea to do, daily

I’ll close this thread out with an update.

 

With some break-in oil in the crankcase, did a ‘seat the rings’ drive yesterday with my son. Kept the engine under 4400 rpms and varied load as mentioned by Jim @jgerock.  Indulged myself with a few WOT bursts. 
 

Wow

 

Maybe it’s the 10:1 pistons or that my original engine was really tired... or both likely. My 17yr old was laughing for most of the drive. 
 

Couldn’t be happier ...Smooth and exhilarating power in the wind up, as a tii should. Although pushing the old engine through the gears was fun, this is something else. The improved gearbox certainly makes a difference. Idle is even smoother than it used to be. 
 

Can’t wait to see what happens past 4500 rpm. 
 

Thanks to all that have contributed and followed this thread. Hope to see you at an event once things open up.

Whoa!  Back the thank you train up.  We need to see some photos of the engine in the car first ?.

Vince- I wasn’t talking about the initial drive (for break in).  Dump that oil after a few miles and repeat the process.

Here you go, Paul. My beautiful engine in my ugly engine bay!

That's more like it. Looks new in the photos.

One of the protective caps on your brake fluid reservoir screws is missing.

Engine looks great!  I'm not seeing an ugly engine bay.  

 

I'm a big fan of clean aluminum finishes and shiny black parts.  Nice work.

lol, how did you know this has been bothering for the last 4 years?! ?

I think I read here that they are still available new, either listed with a p/n at that location or at the ignition relay box near the passenger firewall on the roundies...
