how can I hit 12's w/ internals

[cmptrphreak]

Alright Im looking to hit 12's with just the motor rebuild, just the internals. My goal is 10 sec's. its a 1990 eclipse gsx. So far i bought ross 8.5:1 pistons .30 over , thinking about sticking with the stock rods, federal mogul rod/crank bearings, balance shaft elim kit, and arp rod bolts. What else should I go for? thanx

I would upgrade your rods while you upgrade everything else. Do it all at one time so you wont need to worry about it.

Also, dont set your goal for 10 seconds quite yet. Having a 10 second car is not like pouring a glass of milk. It takes years of learning to get to that stage.

are you implying that your not going to upgrade the turbo, fuel system, intake, ex. system, etc? your just going to build a "race" block and call it quits? Sure a 14 has gone 12's, even 11's, but not w/ out some supporting mods first. You need intake, exhaust, before you try to go running 12's.

For your block though. If your trying to someday go for 10's , then just to be safe, go w/ some Eagle, Scat, or even better, some Crower, or Manley connecting rods. My personal preferene would choose Wiseco pistons over Ross. Id go w/ ACL main and rod bearings, ARP rod, main, and head studs. BSEK, a cometic HG, and so-forth. But w/ an engine built to be race ready like that, Id slap a huge 60-1 turbo on her w/ 750cc injectors, and DSMLink.

And a partridge in a pear tree.

It's good you want to hit 10's and everything and changing your internals would have been neccessary at one point, but you could have hit 12's with a lot of the bolt ons that were previously stated and some good tunning. Even if you didn't get a bigger turbo right away, your 14b with a bigger fuel pump some race gas a SAFC to do some nice tunning and some good driving you could have been there. But if your going for 10's your def gonna need atleast 400awhp and that is if you have some real nice weight reduction. I'm not gonna tell you what turbo setup to go with cause there are a million choices but you need to do some reasrch befor you start buying parts.

Your 90 gsx came stock with the 1g big rods which if you get shotpeened and stress relieved are good for 500 hp. YOu could just go out and get some forged rods and not have to worry about hp limits for the most part. Your pistons should be fine for your goal. You should def look into a performance HG and some arp studs.

Its very slim to nil that you'll run 12s with just swapping internals. They are not one of the key factors to making big power in most of our DSMs. A good 2G Piston/1G Big Rod will take you to 400awhp+, on a good tune with no detonation... Its not boost that kills your internals its the detonation(knock).

If money is no issue, get some Crower rods (Eagle rods will also do great, plus they are considerably cheaper) with Ross pistons (now some will argue, Wiseco or JE, but this isn't a thread for that..) and you'll be set to put down enormous numbers. If your goals are infact 10s down the road, i'd atleast get some Eagle rods to replace the 1G Big Rods... It'll just give you even more room for error, which like it or not is probably likely when tuning is coming into play. Also have your block decked, head re-surfaced and use nothing but a Mitsu MLS Head Gasket & ARP Head Studs.

If your are infact intending to run 12s with your 14B, be prepaired for some race gas, proper cool down times for your stock IC and some good tuning. Alot of people have run 12(even 11s) timeslips on 14b's, but i'm sure most of them agree they are a minority in the community and its not exactly as easy as some of them like to make it out to be.
