not sure, but a 89 model unit from rx7 is a great upgrade, take the open to another 1-1.5" larger. think it measures 3" total.

I think the one on our XR2's is one of the larger VAF units available. The N/A model is definately smaller.

[moot]

so will aq rx7 one plug in and rocket your saying there big enough as is?

[Rocketman]

I've never messed with them never really felt the need. There are much better areas for improvement, especially upgrading to a full-standalone ECU with electronic igniton and MAP based fueling

[moot]

im not the dumbest guy in the world but i dont think  i could do any of that and those are about 2k right>?

You can pick up a used Haltech for around $600 or even less, they're fairly comprehensive units

Megaquirt is also a great way to go, basic DIY kit starting at $140 and going on up to around $400 depending on what version and hardware you want, You'll need some accesories but usually isnt way expensive especially if you go junkyarding. (http://www.diyautotune.com) Most expensive thing you'll need is wideband O2 setup and basic ones are even pretty reasonable now. But the whole setup allows literally complete control over every aspect of your engine. Definately nowhere near $2k. (There are 2k+ systems out there but not worth it for a little B6T)

There is even a "DIYPnP" Megasquirt out there with the proper female harness connectors, allows you to use your stock harness without splicing. Still needs some internal wiring but its easy to do with a pinout for the harness connectors. See: http://www.diyautotune.com/catalog/diypnp-nippon-denso-52pin-unassembled-kit-p-390.html

As always do as much research as humanly possible before digging into it but the results are well worth it in the end

[moot]

so if i buy an engine manigment system would it come with instructions for wiring and stuff or

[Rocketman]

research.

[rcicustoms]

its simple, research 3 times and build once... or reasearch 1 time and build 3 times....
research, trial, and error is all this is ....

has anyone actually done this to a capri? it doesnt seem that it would be too difficult to do it would just take some time and money...

rocketman this means that it eliminates the need for a chip right? bc every variable can be controlled.. as for the end result would it be better overall than a chipped ecu?

[Rocketman]

Megasquirt or standalone? You replace the entire stock ECU with a new ECU, no need for a chip then.

There are a lot of 323 GTX guys running standalone, and a lot of Aussie guys running various types of standalone. I've run MS on my capri when I was still running the 1.6 but do not have it installed now.

End result = capable of being tuned, can run any size injectors you want, very versatile.

MS has a pretty steep learning curve, if you build it yourself you'll want to have a pretty firm grasp of electronic circuits and soldering/assembly. The tuning can also be a bit tricky you DEFINATELY need wideband.

Here's a decent guideline:

Power goals
Under 200-250 HP - Chipped ECU
Over 250 HP - Standalone.
