325i on throttle bodies

Post Sun Apr 26, 2009 11:05 pm

Just wanting to know if anybody has converted a 325i to running individual throttle bodies and what the cost, gains etc are? Cheers Chris

not cheap but have a look here http://www.e30zone.net/modules.php?name ... highlight=

Here's some i made earlier

There not quite finished yet,but it's getting there

Manifold is made from 2 standard 6 pot manifolds.
Throttle bodies are by Keihin and from a Suzuki GSX600R

A lot cheaper than Dbilas/Jenvey etc.

im maybe selling some if you twist my arm enough

I'm working on some too, but they're in the draw at the moment as I've got other stuff at the mo:

Have a search for Dbilas, if your having to pay labour in making up a set they work out considerably cheaper and easier to set up

Looks very expensive. Maybe il go down the s14 route.

^What he said

Dbilas is the way forward. I've seen a home made set up and in trying to save money it cost too much time (labour charges perhaps apply) to set up and get running correctly.

If it is simply a case of setting it up for fun then go for it!

Good luck, genuinely, to those having a go with making them themselves. It's great to see all this creativity put in by genuine enthusiasts.

indeed on the dbilas, mines more of a project than anything else just to see if I can make a set

Mine are just being done to a limited budget tbh.
Means a lot less financial outlay for me, and didn't want to pay £350 for a bespoke inlet manifold to run 12 injectors.

IIRC the Dbilas setup still need a mangement systemand mapping to make it work, although it does look very nice.

I have throttle bodies on my 2.7. I don't know of the performance benefits yet as I am still waiting to have it mapped. They make a great noise

I think if you retain the AFM you can use the chip supplied by dbilas to run them

You may well be correct.
I haven't looked that far into the Dbilas setup

Come on man get it mapped !

I need someone (Ant or someone else if he doesn't want to?) to do it. Haven't got the knowledge to fully trust myself to map it properly.

S14 conversion is going to be waaaaaaay more expensive!

If all ok with Ant happy to lend my services for more mappage

Really? I Thought it was just a case of altering the wiring and manifold!

Have a look at S14 engine prices and you will

Thanks for the offer Shakey, appreciated. I'll let you know
