What is the difference between Stage 2 and Stage 3 kits.

[beanfree]

I did a search and could not find any useful info. Also checked Technic Engineering's site. Anybody know what is the difference between Stage 2 and Stage 3 kits. Thanks.

Yes, THANK YOU for asking, I often wondered the same thing. They use the same exact compressor, but other than that, the website is vauge....(or no info at all). Please, Samir, could you link us, or elaborate on what do all four stages include??

Stage II uses a TM15 blower @ 8 PSI
Stage III uses a TM17 blower (which would yeild more torque) @ 9.5-10PSI

They also should have different software, but I'm not sure if the injectors are the same.

Don't quote me on the above, that's just from what I remember.

stage one uses the TM-12 turbomex compressor :)

Do you need internal mods to run the stage III???

No. I am running Stg III wtihout internal modifications (less cams, and a ported and polished head).

Well When I spoke to him yesterday he said that

Stage 2 and 3 run off the same blower Which is TM15 just that stage 2 has a 8psi pulley and that stage 3 has bigger injecters plus a 10psi pulley with ecu re-done.

Also that when going to a stage three it is best to change the headers cause they are only good up to 300whp.

Hope this helps
