I'm not sure where to start with this so here goes

Just as the weathers getting reasonable and I can carry on with this project someone on here (Reeco) decides to sell a set of new Jenvey ITB's at not much more than I paid for my knock off OBX ones so just out of curiosity I had to have them 

At first glance they are identical but looking closer the Jenvey ones are far superior.

The castings are better and of better quality aluminium with no impurities unlike the OBX ones

The machining is more accurate, I haven't had to finish tapping holes or countersinking and everything lines up without me re-drilling holes

The throttle bodies themselves open and close more smoothly

The supplied fuel rails will also fit unlike the OBX ones

 

After the initial fitting issues of the OBX ones were sorted the only thing they still occasionally do wrong is not closing fully causing it to idle a couple of hundred rpm faster than it should; on a track car this wouldn't get noticed on a road car it's a little irritating but not a big deal it's also doing it less with use

So without a doubt the Jenvey ones are better but are they worth £1400 more than I paid for the OBX ones an extra £600-700 on a road car I'd say yes but not £1400

but that's just my opinion

 

But now I do have a set of Jenvey ones for near OBX money I'm already preparing to swap them over

I've already drilled and tapped the manifolds for the vacuum system and also made some insulating spacers to go between the manifolds and the throttle bodies to help overcome some of the temperature issues with the current setup 

 

 

 

I’m sorry if I missed it but what are you using for a cable stay for the throttle cable.

Keep up the great work!
