93 7 bolt or 92 6 bolt which should i use! HELP (a bit long)

[ekizenbe]

hello. i am currently in the process of restoring a 93 talon tsi. as of now it has the stock 7 bolt that i recently got running. It needs a complete gasket kit and maybe new rings.
But i recently recieved for free! a 91 or 92 6 bolt motor. here is my problem. I was offered 500 bux for the 6 bolt longblock-head,block ,internals and oil pan. I could use that money to rebuild the 7 bolt and go from there, or i could take the 6 bolt assuming the compresion is good, put all new gaskets in it, redo the t belt oil pump water pump and tensioner, remove the balance shafts and put it in using all the external parts from the 7 bolt setup already in the car. My goal is 300-350 hp but someday i might want to go higher(maybe) i dont know yet.

either way i want to remove the balance shafts from whatever motor i use, put in a new t-belt, tensioner and water pump. and make sure the oil pump is in good shape. My goal is between 300-350 hp using an evo 3 16g and exhaust mani, 550 injectors and all the other supporting mods. also seeing as i dont make a terrible amount of money i was going to use the money from the sale of the 6bolt to finance the begining of the 7 bolt redo. but if the 6 bolt is really that worth it , ill bite the bullet and save up some more.

what would you guys do. Are they any other things i should do to the motor i will use to make it daily driver reliable.

thanks so much, i need to make this decision very soon.

Well I dont know if this help you any but my 93 eclipse started out as a 7bolt n/t
and back in I think April I bought a 90s 6 bolt gst motor. My motor was completed 2 weeks ago from this specialist I know who only works with dsm and hes really good.
The motor has new rings, crankshaft, bearings, pistons, and all of those bottom end internals are specially cryotreated ( race proven technology to significantly strengthen metal) and the cylinders were slightly polished, and the exhaust and intake manifold was port and polished, the head was shaved and resurfaced, a new water pump was installed, and the intake manifold was honed. Unfortunantly didnt have the money to get a new oil pump, but this guy really only charged me 600 bucks for all the motor work he did, plus I give him my old n/t engine and tranny, and I payed 500 for the 6bolt gst motor itself including all the turbo assecories needed, and tranny, and ecu. Just not the wiring harness , I am now in the process of wiring it in using my originial n/t harness and only adding 5 new wires needed to the ecu to make it work like any gst. I basically decied to go the long route and do it right the first time, ( of couse lucked up on some of those prices ) but to make a long story shorter, Im not saying go my route but I think you at least should just take your time and do it the right way especially if your serious about the car, serious about making a lot of power, and thinking youll probably keep your car for a pretty long time, just do everything you would to the motor while its out because once its in youll wish you had when something needs to be changed, or your not hitting 12s like you may want.
Unless your on a big budget and have no other car to drive then that always come first, but do what you can do to the best of what you can do in my opinion.

if i were you bro i would get rid of the 7 bolt asap and get the six bolt. you should try looking around about 6 bolts and 7 bolt motors hopfuly you answer in the end will be 6bolt 100%. if i were you i woldnt take opinions and make a quick decision. take your time and read the strait facts about both 4g63 motors and make your decision both will require a good ammount of money so choose what you will be happy with is all i can say. (alot of peole will have somthin to chime in about this question)
just as a jump start check http://www.roadraceengineering.com/walkingcrankshaft.htm http://www.angelfire.com/pa4/crankwalk/<--check the bottom links on this link these are on a 7bolt incase you havent heard about this problem. and good luck bro

I'd have to be the odd one out and say stick with the 7 bolt, simply because this "crankwalk" doesn't occur on EVERY 7 bolt. So I'd say stick with it. I am running a 7 bolt I just removed my balance shafts. I'm running it this way build it up while I search for a 2.4 block as a spare.
