Idle screw is full closed and it idles at 800rpm at normal temp.

I have everything except the modulating valve. Exhaust shop told me that the bend is too tight for O2 bung. How far back does the bung need to be welded?

I don't understand how idle speed mode would be fine after a few miles of driving.

That was not my choice in the first place. I'm in the process of getting those parts to put them back on. The previous owner removed them. Anways, how would the egr valve drop my vacuum when cold? I checked the plugs for gas saturating and the were fine. So I pretty sure the o2 sensor missing...

Not by my choice. All of the emissions parts were missing when I bought the car. Like I said, I just got the rebuild out of the way. I didn't see how the egr missing would make my engine vacuum drop.

I finally finished my never ending rebuild. I've got all but a couple of problems worked out. First, when I start the car in the morning, it idles at 1500rpm. I'll let it warm up for about 5 minutes. When I come to the first stop the vacuum will drop gradually from 18 to 12in/hg. The funny part...

Thanks for the tips guys. I've heard that when you use MLS headgaskets, you need a seriously great finish on the head/block. How could I make sure my machine shop doesn't bs me? They quoted me $45 for head and $75 for block plus $125 for bore, hone, and clean. Any advice with this or if anyone...

I'm rebuilding my 7mgte b/c of a spun #2 rod bearing. I was hoping to get some opinions and advise on what brands are good and bad. NPR pistons/rings, Eristic gaskets, ROCK gaskets and bearings, Topline, etc. I'm building it for 350-400hp range daily driver. Mods are as follows...ARP head and...

Check out www.importperformanceparts.net. Cheap but quality parts. They carry Topline everything and also ARP and Cometic MHG. I think I also saw a 3.4L stroker kit for the 7m as well. Good luck with your build.

Alright. Finally got a lead on a good used turbo head in NC. My friend knows the guy, so he said it might be a freebee. I figure that I can resurface the head and crank, hone block, and rebuild my 7m with new oil pump, rods, and cometic mhg. How"s that sound to ya'll? I fgure that 300whp will...

The cheapest JDM engine I could find was $1000+shipping. Shipping from CA to SC is an arm and a leg. I plan on rebuilt head/cams, cosmetic mhg, topline gaskets and oil pump, arp mains, and acl duraglide bearings. The bottom end is still untouched and in great shape. Between rebuild, parts, and...

Spun No2 rod bearing. Metal in oil got between cams and journals. That killed the cams, cam journals, No2 rod, and probably oil pump too. I think the prior owner installed a n/a bottom end on a turbo head. What do you think?

I need a new or rebuilt cylinder head and I could use some advice. My best option to date is a rebuilt one from Importperformanceparts.net. There I found one for $590+shipping with new cams installed. Is there anyone that has delt with them before or knows orf a cheaper way. Also, I discovered...

Thanks guys. A couple more questions though. Do all 7mgte have oil squirters? Any recommendations on a importer for a used 7m engine? I think I'm gonna get a jdm n/a 7mge. I'll rebuild the bottom end of the 7mgte and use the n/a 7mge top end. Thanks again.

Got done disassembling block last night. Previous owner must have spun a cylinder #2 rod bearing. There are shavings in the head and pan. Oil pump screen is covered with metal. I think I can get the crank polished out. As for the rest of the engine... I think it's screwed. Anyone got advice on a...

I don't think the machinist did any wrong. I used a oem gasket with arp studs@ 80ft/lbs. I didn't notice anything wrong until I drove it for about a week. I know the guy I bought the car from over torqued the cam caps. I started engine tear down last night and found the oil pump screen was caved...

I have a 88 7mgte. After having my head resurfaced after a blown headgasket, my engine lacked a little power and started to make a piston slap noise. Both the cams are under spec and the cam journal bores are slightly out as well. Is there anyway to avoid replacing the head? There is some...

I'm looking for a universal screw in type. Do I need a heated or unheated or does it really matter? I'm running a 3 inch exhaust without cats and garrett t4. Which one do I need guys? Thanks.

Can you reuse the stock head bolts? If so, does anyone know the specs for the max bolt length? If I use ARP head studs, what do I need to torque them to? I'd appreciate any info or opinions you guys would be willing to give. Thanks.

I'm having the same problem too. I think mine might be a bad ecu. Testing it tomorrow along with other things. It started up yesterday after the exhaust was loosened a little. It would idle at all and would run only when it was given gas at 2k. Today nothing, just some backfires and plenty of...
