Looking at rebuilding my engine. Its fine as it is, has a little over 100,000km on it. (i have a 91 tii) I don't see any point investing in a huge turbo upgrade where a rebuilt motor is nearly the same in cost and would increase reliability tenfold :P

Just wondering if its possible to build my s5 up to REW standards (as close as it can get, REW stationary gears, bearings, extreamly large streetport, clearence rotors etc..) or get a 13b-RE and rebuild that (similar setup)

Only downside to the 13b-RE rebuild/swap is added expense of getting a core + swap stuff.

I'll be rebuilding/porting either regardless so is there any limitations as far as porting/rebuilding goes?

So basically trying to make a ported s5 13bt equal to or greater then a ported s6 13b-rew. If not possible i'll just get a 13b-re and rebuilt that.

edit: Car already has Microtech lt10s, wideband, elec boost controller, 255 walbro, 850cc secondaries. All emissions are removed, OMP gone, running premix.

If the engine is fine as it is, I would dump a bunch of money into external parts such as reliabilty mods, turbo upgrade, fuel management, etc... and run it until it blows... THEN rebuild the engine. No point putting money into rebuilding an engine that doesn't need rebuilt.

^ I edited above. Car came with all the goodies just begging for more boost or bigger ports. I have the stock turbo right now, but its lacking in the top end. If I do a turbo upgrade, I'd want a divided exhaust manifold, twin wastgates and a divided turbo. (trying to keep response stockish but with a larger turbo )

I don't really feel like dumping a bunch of money into a new turbo setup to just boost the crap out of a stock motor that i don't trust.

Would rather rebuild now, and get a drop in like a bnr upgrade to hold me over

Besides, its alot cheaper to rebuild a non-blown motor.

So you gonna rebuild with new parts or used good parts?
