I want to push for about 300-400 hp but can the stock block handle it. Also I know the oem axels won稚 last at all. What axels and will pushing for 350 or 400hp worry me or stress my engine?

 

I don't think you would want much past 250 horsepower to be safe. Especially on a 25 year old engine with a lot of miles. Your transmission is also unlikely to handle that either.

If you want to do that, take it apart and just do it right, forged pistons, new rings and all that, and I am presuming you are going to turbo it, so then take the tranny out and have it rebuilt (or do it yourself).

The whole car is not made for this at all. But if you spend enough money you can make this work. I'd set about $10K aside to do it right. Engine, cooling, transmission, suspension, etc.

Or swap it out for a different engine, make a K swap.

If you are serious about building up something, then read this and follow the recipe this person used to make a killer setup:

This is an F23A with turbo and correctly built parts to make it hold together.

 

Stock block = 300whp max without sacrificing reliability immediately.

Rod/piston engine = 400whp and stock sleeves will now pop at any time.

Fully built/sleeved engine = you will max out at 550-600whp after dumping many thousands into it trying to overcome the limitations of the cylinder head and platform in general. you will also be destroying transmissions constantly.

Your transmission/axles will be fine up to about 400whp, as long as you're not doing childish things like clutch dumping from a dig on slicks without preloading.

As stated above, you basically have to upgrade the entire car as the suspension, brakes, tires, bushings, etc etc were never designed for the added power and will collapse under the strain. It's getting hard to recommend modifying these platforms anymore as the clean/good examples are gone and parts are getting rarer/much more expensive all the time.
