Michael,
I'd love to, but I won't be able to get to anything other than NASA mission work until after the 13th of this month. I'm already working 14 hour days at work getting this mission study done, so there's not much of me left by the time I get home

Can you realistically commit to doing it then? I can have it to you then.

Have you looked into the cometic mls head gaskets? I found some here.

I run a set of stock subaru gaskets and head bolts on my WRX hybrid. I push 30 psi on race gas and have not had any issues. These should be just as good.

good luck chuck, you're going to need it if you are still going to work on it tomorrow give me a call and i'll swing by after work.

Probably a year. Depends on how long it takes to finish the motor. Then there is break in, a new exhaust and downpipe w/external wastegate, not to mention the FMIC and tune.

I may show up with my mildly modified WRX. I'm making 266 WHP 258 WTQ on a mustang dynojet with that car. Its been real reliable too. That is my daily driver.

Ha Ha. That is too funny

I actually saw these, but I don't know if they actually make them???? They are supposed to be real good though on the 4 cylinders.

Thanks for the hoist and for the offer to help. I'm going to try to do all of the setup work tonight and tomorrow night. I probably won't pull the engine until Saturday morning. I have to do a presentation Friday morning so I don't want to get too greasy. I got the boxes to ship the cams in from Mike yesterday, so I will ship them out on Monday.

Nice Fiero. Good condition. It's going to be sick with the 4 liter northstar engine.

So far I want to make a list of things people will need in order to build or simply rebuild their engines in the future... used motors are thinning out so they are becomming less of an option... this is also and attraction to those of you looking to keep matching #'s


1. Old engine
2. New pistons (OEM or Aftermarket)
3. New set of piston rings... Now these cost a ton from the dealers so I would suggest doing some research on 2.2l rings to see if there are aftermarket matches
4. Piston pins... Your old ones might look good, but not worth it to leave holes in the rebuild
5. Engine seal kit... Contains EVERYTHING for a total overhaul... even new piston pin clips and valve stem seals
6. Find a competant machine shop to hone the cylinders to spec
7. Have a machine shop follow LAN's guide for checking the specs on the crankshaft.
8. Rod bearings- these are the same bearings used in 2.2l's get them in either std sizes or the recomended oversizes. You will need 2 sets or 6 pairs
9. Main Bearings... same deal as the rod bearings. You will need 2 sets
10. Head work- Your valves are probobly still good. But have a shop do a valve job on the heads and clean everything up, not to mention checking for warping in the heads and block
11. Assembly... this is not for a shade tree mechaninc... it is a complex proceedure that requires several specialty tools (some you can make yourself). If you second guess your abilities at ALL... have a professional do it.

There is more and I hope others can copy and paste what is here and add to it

Do you guys want me to cary rings? If I do will anyone actually buy them? I can stock them for $150 for a set of 6.

Stock spec rings? I'd be along for that, $150 is MUCH cheaper than OEM, and I'll be needing some soon-ish.

Will the engine build be accompanied by a new engine management software? I'd imagine that with the new cam profiles and compression ratio it would take some tuning to get the best results.

[longassname]

Yes, stock spec rings.

[SVXelerator]

stock spec, but in different oversizes to account for cylinder wall wear?

moly rings?

different material for compression vs oil, or the same material for both?

Perfect Circle?
