Quoting RvlutionMtrsport:
Call JNZ tuning (or pretty much any DSM shop) and buy:
1991 Galant VR4 Complete Engine Gasket Kit
Timing Belt
Balance shaft Belt or bs shaft delete kit
Hydraulic tensioner
Tensioner pulley
Water Pump
rod and main bearings
You might need pistons and rings if you're doing full rebuild.
I would also buy a new set of stainless valves for the head and new bronze guides. The engine gasket kit will have valve guide seals. Get a valve job, r&r the guides, resurface and clean.
I'd use better than stock gaskets on the hot parts (manifold, turbo, o2 housing).
RRE has really good ones. 4 layer manifold - head copper gasket, thick stainless 7cm turbo - manifold gasket, stainless turbo - o2 housing gasket, new o2 housing to down pipe as well. You might want a new front o2 sensor too. I'd also inspect the knock sensor and make sure it's good. If you have any plans to make a good amount of power I'd probably get a set of ARP head studs to put it back together with. Depending on your end goals, you might want to do the mains as well.
I always stick to Mitsubishi parts.
i already have a lot of this stuff so i guess i'm more on my way than i thought. my initial goals are around 400 whp after the rebuild and some more bolt ons. while i am rebuilding i want to go ahead and get the pistons and rods i want, as well as boring the head out. most likely gonna go .020 over. have water pump, all mitsu OEM timing parts, BSEK, and i plan on buying one of the 7cm stainless turbo gaskets from extremepsi.com. they are only like 12 bucks. if u know where to get one cheaper lemme know. as for a full rebuild gasket kit i have found one from cometic and one from fel-pro. the cometis has good turbo gasket parts, but is missing a few things i will have to buy seperately (ie the half moon plug and the spark plug tube gaskets) plus it doesnt come with a head gasket. also CR, you say that i should plan on spending about a grand, huh? well my plans were more like 2500 or more...after the machining and the parts and everything i don't see any reasonn it is going to cost less. also one more question. i have been thinkin about cams lately too. figure if i am rebuilding, might as well get everything i want at once and not have to tear it apart again ya know. what is a good company? i have heard good things about BC but there are a few other brands out there, some cheaper some more expensive, just looking for some personal experiences to go off of. thanks everyone.
