Rebuild or Swap???

[NylenS]

I have a 93 Talon TSi and the timing jumped and pistons hit the valves. I am wondering if it owuld be better for be to buy a engine off this sight as posted in the marketplace (which one would be the best bang for your buck?) or if i should spend the money on rebuilding the motor i have. I would deficately do intake and injectors no matter which way i go and i would do a spark tech ignition (are these ignitions any good). I am also planning on putting a Garret 50 trim turbo on so I am just wanting to know which route woule be better for me.

If i rebuilt i would convert my seven bolt motor to a six. What would i need to do this.

If i do all this stuff would i need to upgrade anyhting in my tranny or drivetrain? I dont wanna start breaking axles and driveshafts if im running a motor with alot of power.

To put a 6-bolt engine in there you need a complete 6-bolt lower end including the oil pump and oil pan and everything that attaches to the lower end basically. If your looking to use the 6-bolts bigger rods then you can have a set macheined to fit your 7-bolt crank. I would say 300hp or less would be ok on the stock drive tarrain (the brighter the flame the faster it burns out).

If your gonna rebuild the engine you have in there now you will need to have your block and head inspected for damage that will hinder your results for a good engine build. Did it break a valve or just bend it?

just 6 bolt swap dude...dont even waste time rebuilding the 7 bolt...having a engine that can withstand more hp stock is always a plus!!

A 6 bolt block, 6 bolt crank, 6 bolt front case, 6 bolt rods, 6 bolt pistons, etc, etc. Basically an entire 6 bolt shortblock.

Also for your question about the Spark Tech, the factory DSM ignition is good to about 500 hp. I'd say spend your money elsewhere.

Either engine, 6 blot or 7 bolt, will handle the type of power that you are talking about. Price it out and go with the cheaper option in my opinion.

Hope this helps!

u could just make a cop setup with intrepid coils

His motor is shot, coils (and a COP conversion) are the last thing he needs to be considering right now. However, even when he does get to that point, with the plans that he has mentioned, the stock DSM coil will be more then enough.

 

[1gdsmftw]

understood but he mentioned spark management! just throwing ideas out...

i do say he should just go ahead and pick up a 91 6 bolt block even if it would seem overkill now...what about along the road when he does decide he wants more?

I dont need to get the head and block inspected. Th ecar would still run if i put a new timing belt on. If i just wanted to rebuild this engine all i would neeed is new pistons and a few new falves and it would be good. I already got the head pulled off and that is the only problem with the car.

I am still wondering if it would be better the buy a six bilt motor and rebuild it the way i want or just buy one of the race motors that are posted on this website in the marketplace.

Personally I would not buy a "race motor" that was built by someone else (classifieds) unless I was purchasing it directly from a reputable shop. You have no idea on the quality of the work that was done or if corners were cut to save some cash. Or if it was used and there are any problems. There is no warranty on that kind of purchase.

If you are on a budget then just fix up the 7-bolt that you have, it should hold the power you want to make without any problems. However if you have the funds and really want a 6-bolt then go that route. It's your car, your call.

Hope this helps! Good luck!

go bought not built man

 

[NylenS]

Yeah i was thinking buy one but I donk kno what kind of power they will produce. And then i still need to do intake and injectors and stuff unless you can order one with all that stuff done.

 

[1gdsmftw]

uhm actually you can use a 2g head on a 6 bolt block just gotta port the holes that the head studs go through is all in fact thats an upgrade for the 6 bolt because the 2g head is not only compatible with the evo 3 intake manifold but the head is capable of being ported out further than a 6 bolt 1g head

so long as u invest in a 91+ 6 bolt block you wont run into much issues...the problem with getting a 90 block is the harness will need to be adjusted to run the 90 specific power pack and the 90 specific tach sensor which is a pain..

i believe to do a 6 bolt swap all you need is obviously the block and a few sensors like cas and such...id suggest though that if u do the swap to keep the pistons in the 2g block and put them onto the 1g rods and get the block honed and bored and run the 2g piston setup it raises the compression by 1 point...which trust me makes a difference

Why not just rebuild the 7 bolt and save yourself a boatload of cash? The 1g 7 bolt isnt prone to walking and 7 bolts are more stable to to the fact that they have a crank girdle. 6 bolts do not.

I looked into COP setup and all of what I read on this site said that they are a total PITA. Unreliable, hard to tune, little gains.

cop setup is actually just to increase fuel burn efficiency not to create any hp gains...its pretty much a state of mind...sort of like the whole balance shaft delete its not for gains..just piece of mind..

anyways...how can u say a 7 bolt is more stable than a 6 bolt when the 6 bolt is actually capable of withstanding higher hp numbers? and when the 6 bolt has less reports of walking than any other form of the 4g63?

 

[NylenS]

I am leaning more towards buying an engine off the site and throwing on an intake and thde 50 trim turbo.

 

[NylenS]

But im wondering which engine would be the best bang for my buck?

 

[1gdsmftw]

well...what numbers will you be wanting to run? 6 bolt can run higher numbers safely on stock internals

 

[FLASH1970]

But im wondering which engine would be the best bang for my buck?

Probably a stock 6 bolt rebuilt.

 

[NylenS]

Im hoping to get it down to ten seconds eventually. But i just want to kno which engine would be best.

 

[boosted_ego6985]

If your looking for BEST and want to eventually run 10s then DEF go with the 6bolt. It can be achieved with the 7 bolt but you need a LOT of work and upgrading to get it to those kind of numbers. The 6 will be easier to get there and will cost you less in the long run. Of course this is just my opinion on the matter but I am pretty sure that MANY would agree.

 

[NylenS]

Oh i am definately getting a six bolt but i am wondering which engine in the market place would be the best bang for my buck.

 

[Jt_4g63]

do the swap its the best thing but if u want to keep the 7 bolt then build it

 

[mcneilmg]

I would talk to a machinist with a reeeeaaallllllllllllllllllllllllllllllllllllllll good reputation. Im in process of a 350 olds small block rebuild. Amazing what machinists know

You'll have to clarify some more, when you say "market place" are you talking from a shop/vendors or from the classified?

And whats your goals beside running 10's in the long run?

Are you on a budget or money isn't a problem for you?

Are you/can you do most of the work yourself or will you have a shop doing it for you?

If I were you I'd just find an unmolested 6-bolt and do the swap, and since it's going to be out of the car you could do a B/S delete and some internals/porting etc. if you have the funds.

If you want to go with a race engine I'd consider going with a 2.3l or 2.4l for more torque, but that's just my opinion.

Hope this helps!

my goal is to get a 2.3 stroker in my dsm before i die
