Need Info and Help for 3.4L Conversion

[nmex]

Since Oct of last year I don't have a boxter any more. I sold the car and bought a GT3 ( Love the car but I realy miss my little convertible) So I am going to buy a 99 or 98 Boxter and do a full 3.4l Conversion to it.

Here are my questions:

Do I need a 99 ( none egas ) or 98 egas

Can the 5 speed trany support the new engine

Is there a diference on the wire harnes between 99 and 98 and a new 3.4L engine

One last there use to be a link on the web from someone that did a full convertion step by step. None of you guys have that link by any chance??

Thanks

You should add on to this thread with questions so we can keep the 3.4 stuff together.

Can anyone offer their opinion on what is the best year and model for a 996 engine conversion, GT3 aerokit, performance suspension, upgraded brakes?

For a little autocross and small track performance is the 5-speed or 6-speed geared best?

Given production quality, base versus S, overall cost of car, engine, and conversion, what gives the best value in the end, 3.4L non-egas or 3.4L or 3.6L egas?

Thanks!

I would think that the newest 986 S would make the best swap. Brakes on the S are, I think, the same size as a 996 (or if not exactly the same, pretty close). You could put a 3.6L eGas engine in a late model, which would give you ~30 more HP than a 3.4. Five-speed vs. six-speed pretty much comes down to personal preference.

The only issues with using a later model is that they are heavier than the earlier models, and a late model S would probably cost around $20K more to begin with than an early mode.

You can put a 3.6L E-gas in the 2002, 2003 & 2004, 3.4L E-gas in 2000 & 2001, 1999 and earlier 3.4L mechanical linkage.

Check for compability between the Boxster and 996 ECU for the year you select.

Good luck,

Can you offer any comments on why you have decided on a 99 versus a later model? Thanks.

yea I been looking at some with lots of miles 70k + that I can pick for 9 or 10k so that is why I can spend about 30K more thatn that I would be on Elise territory but after last week Auto cross and seeing the elise lac of power I rather have a 986 :)

Look at the attached picture from Laguna Seca. the Elise could not catch us let alone pass. All the Boxster ever needed was more power. At 3000 lbs the Boxster out handles many cars, all you need is more HP.

When you buy your Elise come and see us on Laguna Seca, & Thunderhill, or Button Willow.

Good luck,
