I am looking at getting a Autotech 260 or 270 for my 1995 Jetta. I am wondering which one would be better to get bc I have a kinectic turbo kit with fmic. Any suggestions would be appreciated.
This thread has some input to to the question you are inquiring about.
I have actually read that thread, but it doesn't completely give me what I wanted to know. The 260 is designed for use with turbo cars and the 270 doesn't say anything about being designed for turbo cars. That is where my question really is. If the 260 will out perform the 270 in a turbo car I would go for it. But I know in a N/A car the 270 would be better. Seems like most the people in that thread skipped the 260 for the 270. And the reason its between these 2 cams is I can get a great price on these.
I am leaning towards the 270.
I'd compare what cams that TT carries, they have good explanations to what application you want to run, turbo or NA. You may need to change your springs to HD springs, I think you're running an OBD1 setup. Been debating between AT and TT cams for awhile myself..

Need ENTIRE build info, entire intake manifold specs, EVERY turbo detail (What wheels, what turbine housing, what compressor cover), what engine management, and details of any headwork and flow chart if possible to give good Cam advice.
Other wise, it is all speculation based off others results.
If you are boosted, you want valve springs with a higher seat pressure no matter what cam you are running. "HD" valve springs, as companies like to market them as, is not a end all of valve springs. If a company markets them to you as "HD" and either provide the spring specs before ordering, or ask you for you cam specs, thats a red flag to go with a different company even IF you can find the springs specs.

John, I am running Kinectic Motorsports MKIII Stage 2 turbo kit. T3/T4 turbocharger (with a .48 AR exhaust housing). As far as more details on the turbo all I know its what Kinectic sends with the kit. The kit uses C2 42# engine management. The engine to my knowledge is completely stock OBD1 ABA internals. The intake manifold is a stock manifold, but I plan on building a custom SRI in the future. I do not have a flow chart available.
Thanks for all the input guys.
