Doesn't anyone know how much they cost about 15M FI heads today :confused:
Nissan was selling them cheaply out of the Motorsport catalog some years back. I bought three of them for dealer cost, which was only $120 back then. They are no longer available.

Yes, I know this, but if I'm going to sell my head, how much I can get from it?

Don't know.

Whatever the market will bear I guess.

Okay, I think that I keep it and put it on top of E15ET block. Then little more grinding to the ports to make them smoother, big intercooler and 15psi :thumbup:

Hi
This particular head came from the states in a motorsports labeled box, but it says 15m on the outside...

I'm building an E16S from an 86 pulsar, and the head is marked 11M as well as the block. The 11M head has restrictive swirl shrouding unlike the 33M head I have now.

Guys,

I have the big valve 15M head from the Motorsport catalog in the USA. Like I said earlier in this thread, I bought three of these brand new about 10 years ago from Nissan. I sold two and am using the last oneon my full race E16. Unfortunately, after 10 years of racing, it broke a rod last week but did not hurt the head at all [luckily]. But it did slightly bend the intake and exhaust valves on one cylinder. I was smart enough to order an extra set of the larger 13202-63A00 31mm ex. valves as spares, [because with an E-series engine if you have a problem with bent valves, it usually always the ex side that gets it]. But I did not forsee a rod failure and a bent intake valve!

So, does anyone here have an extra 13201-15M00 37mm Intake valve for an E15ET Pulsar turbo or 15M F.I. head to sell me? Help! :(

Oh man, that's not good to hear. Hope you find one. Guess maybe I should have bought that thing a couple months ago when we talked... :waving: Just wasn't to be I guess. Loren

Loren,

Good to hear from you. I'm glad I didn't break the car up and sell all of the good stuff now. The car club I belong to just started a new euro-rallycross series and I will be using the car regularly again.

Great news, although there is a mark on it where the piston touched it, the 37mm Motorsport intake valve is not bent after all. I checked it with a dial indicator today. Very lucky indeed. So there was only one slightly bent exhaust valve and I have four spares. Dodged a bullet there. :)

For those of you who have always wanted to know what a chamber looks like on a 15M Motorsport cylinder head here's a pic:

I really wish we could have taken you up that too. I'd be racing now instead of wishing. Keeriste, the power would have been about perfect since I did some figuring. Been taking the daughter's G20 with the SR20DE to the autoX. It's about 2850 lbs. with 145 hp. The Sentra will be sitting at close to 1600lb. and if it got even close 120 hp and comparing it to the acceleration of the G20 it'd be pretty darned fast. 1.5 hp/lb. should make a good difference between the two. Need piston to valve clearance spec so I can get on with it. Good to hear from you too Mike.

since ive never seen one upfront i cant tell...
I have the exact same Nissan, 1987 B12 XE coupe. Where should I start hopping her up? I have some ideas but you can point me in the right direction.

Ever had a problem with head gaskets blowing in the E16? I've been through 2.
