It went through to the water passage, but if you seal it up good, it'll be fine. Link to comment Share on other sites More sharing options...
MontyTSI Posted February 27, 2009 Report Share Posted February 27, 2009 So what happened to this other motor? I may be willing to purchae it if its still available. Pm me with details if you want to share Monty Link to comment Share on other sites More sharing options...

Technology Posted March 10, 2009 Author Report Share Posted March 10, 2009 Well, I am assembling my new shortblock with my marnel, which I found has two broken valve stem seals - soon to be replaced though. Here are a couple pics before putting the head on. Forged .030" over wisecos ~8:1, shot peened rods, crank ground 20/20, all rebalanced, no silent shafts, my fidanza and ACT HD street clutch, which will soon need to be upgraded, lol. AJUSA headgasket seen here, ARP head studs and rod bolts, I think the bearings are ACL. What else... I port matched the intake ports on the head and magna so fuel doesn't hit a wall and form droplets (hopefully that works). I'm going to be grinding the exhaust manifold to match the gaskets at the head and the turbo for less turbulence (if that matters). http://www.mitsustyle.com/photopost/data/529/medium/DSC02563.JPG http://www.mitsustyle.com/photopost/data/529/medium/DSC02564.JPG I'll take more pics of the install as it moves along.

Coke Posted June 12, 2009 Report Share Posted June 12, 2009 Andrew...after seeing your setup at Nat's this past weekend, I am very interested in doing the same thing to mine. I'd like to have a word with you, sometime. I could use some advice, tips, etc for when I get ready Justin Link to comment Share on other sites More sharing options...
Technology Posted August 12, 2009 Author Report Share Posted August 12, 2009 It's been a long time since I've updated this thread. Things are going well with the engine, it's held together just fine. I've worked out a bunch of little kinks, but there are a few left. A couple of the valves weren't lashed properly and have "mushroomed" or deformed on the top where the lifter hits them. So, I'm going to get stock length valves and go back to hydraulic lifters for less maintenance. Then I need to track down a couple leaks and get an idle control motor, then it should be ready for the next round of mods/tuning, etc. Link to comment Share on other sites More sharing options...
Technology Posted October 15, 2009 Author Report Share Posted October 15, 2009 (edited) Updates: The engine's back apart to get o-ringed. I made too much power for a stock style head gasket setup. Anyway, I'll let the pics do most of the talking. New clutch.http://www.mitsustyle.com/photopost/data/529/medium/DSC02997.JPG Here's where the #4 cylinder leaked horsepower into the coolant passage.http://www.mitsustyle.com/photopost/data/529/medium/DSC02998.JPG And here you can see where it leaked out the driver side on 2 and 3, #1 escaped on the passenger side. (not the burned looking areas).http://www.mitsustyle.com/photopost/data/529/medium/DSC02999.JPG I took most of the stuff off the block today. Need to get the crank, pistons and rods, out, then take it in for the machine work.http://www.mitsustyle.com/photopost/data/529/medium/DSC03000.JPG And here's a picture of thousands of dollars somewhat well spent.http://www.mitsustyle.com/photopost/data/529/medium/DSC03001.JPG And this is why.http://www.mitsustyle.com/photopost/data/529/medium/DSC03002.JPG I think even on this printout it shows a little clutch slippage right before the torque peak. I could be wrong, but after this point it slipped the clutch and lifted the head. Pretty much at the same time.

dmyers151 Posted October 16, 2009 Report Share Posted October 16, 2009 What size core is your intercooler? I couldn't find where you posted dimensions, if any. Link to comment Share on other sites More sharing options...

Technology Posted October 25, 2009 Author Report Share Posted October 25, 2009 (edited) Once I get it all back together, the foreseeable limits are (in order of what I think they will be):1. Injectors2. Fuel pump3. Transmission? But at the last dyno session it was gaining about 15hp per lb of boost, which is really good. So 9 more psi puts it at just about 500whp, assuming everything stays the same. cross your fingers. Edited October 25, 2009 by Technology Link to comment Share on other sites More sharing options...

Technology Posted November 14, 2009 Author Report Share Posted November 14, 2009 I got the block back, looks amazing. I am waiting on new bearings and piston rings, then I can assemble the short block again. Got the flywheel resurfaced and the new pressure plate balance-matched. I'll take some pictures when it's going back together. The head will be getting late-model hydraulic valves and hydro rockers, and the combustion chambers will be getting all smoothed out and bore-matched with the block. I may have to carry it down to the basement for that, since there's a lot of light down there, and not so much in the garage. Link to comment Share on other sites More sharing options...
jahjah Posted November 16, 2009 Report Share Posted November 16, 2009 Whatcha mean "late model" lifters? Link to comment Share on other sites More sharing options...
Technology Posted November 22, 2009 Author Report Share Posted November 22, 2009 I mean not the mechanical '83 lifters. Anything after that would be late model, I guess, haha. Stock basically. Anyway, back to work on this thing. With the block back, I put the head on and flipped it upside down to see how much of the combustion chamber wasn't supposed to be there. And you can see this picture, and the rest of the cylinders were like this: http://www.mitsustyle.com/photopost/data/529/medium/DSC03015.JPG here's a close-up http://www.mitsustyle.com/photopost/data/529/medium/DSC03016.JPG So, I bought a scoring pick and reached in and did my best to trace around on the head where it was showing in the cylinder. Then I ground it away, and will take all the sharp edges off the chamber, then polish it like Artinist did. I figure it can't hurt at all. It might even drop the propensity for knock with such a proliferation of sharp edges. Link to comment Share on other sites More sharing options...
Dad Posted November 22, 2009 Report Share Posted November 22, 2009 http://www.mitsustyle.com/photopost/data/529/medium/DSC03016.JPG Is that a crack between the valves? Dad Link to comment Share on other sites More sharing options...
Technology Posted November 22, 2009 Author Report Share Posted November 22, 2009 It is. If nothing else, I can use a stock jet-valve head. This pile of crap is fighting me. Link to comment Share on other sites More sharing options...
8ty8starion Posted December 10, 2009 Report Share Posted December 10, 2009 (edited) Keep it up man your inspiring me to keep going with mine! I do know the jet-valve heads are much more likely to crack especially under you circumstances! You may be better just keeping that one!

If you give up now...it will be so bad that you went through all this for nothing. Just keep imagining that 500whp Link to comment Share on other sites More sharing options...
Technology Posted December 11, 2009 Author Report Share Posted December 11, 2009 Well good news, we pressure tested the head up to 30psi and it didn't leak, so it's getting final polishing (by me), skimmed to clean up the surface, and I will be ordering 1mm OS stainless valves pretty soon here. Those will go in, I'll reassemble it with hydraulic rockers, put it on the engine, which will also be done pretty soon, then toss it in the car and get it tuned for more power. It'll go plaid.

Technology Posted December 12, 2009 Author Report Share Posted December 12, 2009 Because I only rev it to 6500, and I don't want to always be checking them (I had solid lifters before). I do plan on taking road trips in this car. I would love to drive to PF or Vegas or whatever. I want the only problem to be not enough leg room. Plus they are quiet.
