Def Turner Motorsports, they have everything. Be prepared to drop some money, theres a load of info on going 2.5 on s14.net. But I must ask why, sometimes a modded 2.3 is just as fast if not faster then a 2.5. A 2.3 with Cams A/N and other minor work will blow away a 2.5.

Dame the complete kit is hot but verry expensive, I was thinking in upgrade my engine to 2.5 becouse a guy in germen have a chipe cramshaft from the 2.5 evo III.
I ´m a litle undecided in what to do in my engine, at the moment I gat a alpha N kit and a carbon air box, in the dino the car is shoing 233 bhp and it´s making 8000 rpm.

Disregard my last post then, thats a nice sounding engine, can you please post some pics of your car or send them to fisher450@sbcglobal.net. I would love to have some e30 M3 cab pics. Thanks.

The 2.5 will have more low end torque and be more driver friendly than a built 2.3. You really can't go wrond either way though:)

A properly done 2.5 that is. The problem with 2.5s is that you have to get quality work done otherwise you could have some problems. Ive seen some last a month and others last yrs. But I suppose this is true with any engine work. The main thing is, if you are going to do it, dont try to be cheap... do it right.

I also recommend going to www.s14.net and do a search. There is tons of info. Make sure you search though...

I wold love to post some picks of my car, but I dont now how to do it, if any one cant teach me how to do that I wiil be grateful.Dhabes i think i´m going to follow your adive, and when I do it I do it well, At the moment I think I´going to chose, in to a new cams or a new complete exaust. I saw in a sapniche compani ( iresa-web.com ) a sport Header System Dtm version, any one now if this is a good Header?

check out gustave stroes' very informative website

Yes, the only way to maxmize spending the money on a 2.5 is to do it right all at once. Speaking from experience (not completed yet) it is not a cheap thing to do, and my engine is only partially assembled at this point due to time.
If you have a 2.3 I wouldnt spend money on a header until you have everything else done, the performance increase is very small with this upgrade. Do cams first, then the header. You will see a nice performance increase with the cams (especially w/ alpha N)

don't do Turner.. I am not too fond of them...

they sell a nice kit and have more BHP for the same $$ as Turner...

I have only heard great reviews for the TMS kit and their service is top notch!!!

VAC is OK, but very bad in communication.

Check to see if you have an airflow meter intact still- Alpha N deletes the airflow meter. Do you have a stock or carbon fiber air plenum?? That would also tell you very quickly.
