i need some help!!!

[1997_GSX_mar]

Hi everyone,
I have a 1998 Eclipse GSX i currently have a 16g set up with some head work done to it full exhaust FMIC, i want to hit the 450whp range SAFELY i have stock internals. The winter is coming soon so I'm sticking the gsx in the shop. I'm under a budget of $2000. what would you guys recommend me doing?

I don't think you'll be able to do it safely for $2000.

Your going to need to:
-upgrade your fuel systems. (Fuel pump, injectors, afpr)
-Bigger Turbo (holset would be your most cost effective route)
-DSMlink or some type of fuel management.

They will pretty much take up your whole budget, and you haven't even touched the bottom end. With your weak 7 bolt rods, you won't be able to get there "safely" or "reliablely." I wish I had pictures of my 7 bolt rods after hitting 260whp(mustang dyno) on a 16g. Needless to say, they were bent pretty good.

Start at the bottom and work your way up if you want to make it to 450whp. Read the upgrade paths in the tech guide. Its not cheap to make it to 450whp. Tech Guide: 2G 4G63t Upgrades - DSMtuners

OK thank you,
if i upgrade internals on my 7bolt will i still have to worry about crank walk? and do you know any good website where i can buy a 6bolt short block? your right it is going to cost me more then 2k if i want to do things right and safe.

you should start with a 6 bolt from a junk yard... a stock 6 bolt will take you to 450hp no problem.. just have it rebuilt with so +.020 pistons and some 272's cams if you dont already have them. thats the most cost effective motor you can get...

also start with dsmlink and fuel system, big injectors and a wally 255 and a AFPR

price all that out it should be between 2-3k

ok see i don't want to buy a 6bolt if i can make the 7bolt better. i was thinking of just buying a stroker kit for my 7bolt? or would it be better to just buy a 6bolt and built it? or just build my 7bolt i only have 85k miles on my 7bolt.? pleas give me idea's Thank you!

You can get away with the 7 bolt with stronger rods. The 6 bolt does have more advantages than the 7 bolt though, beefier crank, better airflow, no cps. If I was you, I'd buy a spare block (6 bolt), and build it while you can still drive your car. Then when the time comes and you have all the parts you need, slap it in.

Why don't you build a 6 bolt this winter and put it in when spring comes? That way you can get to your goals safely without rushing and potentially blowing up your engine

+1 on building a 6 bolt over the winter much safer and cheaper in the long run. I am going to try in do the same I have a na 6bolt block with 67k on that broke a t-belt thats just calling to be rebuilt. Also I picked this car up out of a guys back yard for 100 bucks he had no idea just wanted it gone! So just keep your eyes open and im sure you can pick up a buildable 6 bolt cheap good luck man.

The 7-bolt has a lighter crank(strength doenst matter, people still make a 1000hp on stock cranks), the 7-bolt has a full main girdle(stronger than the 6-bolts two-piece), the 7-bolt has better desined oil gallies for better flow(, even with crankwalk). The airflow part is arguable but just because the ports are bigger DOES NOT mean it flows better. Magnus started removing the oil squirters on the 7-bolts and has yet to see one crankwalk. 7-bolts can handle 450awhp, Curt Brown made 470somethingAWHP on a completely stock 7-bolt WITH A 16G. With that in mind do you really want the pain of swapping a 6-bolt that will just allow you to make more power on a stock block(which is usely used and has a chance of being in worse condition than yours). A built 7-bolt is better than a built 6-bolt, period. Over the winter you can build the 7-bolt(or just throw some evo pistons/rods for ease and no down time) and have a NEW MOTOR that will last if all precautions were taken. Then again a 6-bolt can be had for cheap and there is very little modding needed to swap in.

ok i just bout a 6bolt for 675 dollers. this is what he sed about it [(up for auction is my 4g63T from my 1991 Eagle talon TSI AWD, this Turbo motor ran great, perfect compression (160,158,160,160) test performed right before the motor was pulled. The motor has 89,876 miles on it and about 10,000 miles ago all the gaskets(on the block) and a new front case/Oil pump and rear main seal. Also a Mitsu MLS headgasket was installed too. motor was pulled because i have a larger displacement 2.4 (G4CS) waiting to be put in. The car never burned oil and always started. The motor is being sold as a long block with head, no pan, valve cover, timing cover, as i had to use these items on my 2.4L. I can include a pan,valve cover, and any other accessories needed but bidder will have to pay the buy it now price. The gaskets and seals in the head are the original ones and probably wouldn't hurt to replace. block has never been rebuilt all oem on the inside. I would prefer local pick-up but can ship( buyer will need to pay exact shipping costs calculated at checkout.. I will be happy to assist in any way i can, and will answer any questions you might have as i want this transaction to be smooth as possible for both sides.
forgot to mention that the motor has a balance shaft elimination kit installed already.)] What do you guys think? my plans are to build this motor all winter?...
