Differences between a S1 L67 TB and S2 L67 TB?
 

I'm looking into a throttle body spacer to serve as a post MAF injection point for an H20/Methanol injection system. Only non-customized solutions I can find are for a Series 2 engine.

As I don't happen to have a Series 2 L67 TB handy, I was wondering what the physical differences are between the two?

Here's an example of a canned solution I found: http://www.pfyc.com/store/merchant.m...ct_Code=WB3017

Any help would be appreciated :-)

you could have one machined for a S1. Looks like a simple part to machine.

Yeah, I suppose I'm going to have to head that way. I was looking for the easy way before I went that route.

You don't have to use a spacer. You only need to inject POST MAF. (trust me on the POST part).

This can be done (ideally) in the SC outelt area, or in the TB itself. ;)

Give me a few days on this. You'll have pics and instructions. It'd be good to know what nozzle manufacturer you've chosen.

So it can be done right into the TB? I ruled that out in my own thinking originally because I was concerned the hole, even plugged by the nozzle would cause some turbulance.

I'm going to be running the Snow Performance MAF kit. I've spoken with them a couple times and they said that it'll work with the Series 1 MAF just fine.

By the way, this is a mid to late March project for me.

You have time. I've identified a spot on the 94/95 TB that can be tapped directly. You'll be the first to see the pics.

Great! I'm looking forward to it.
