Hello, recently discovered this website and it is far better than anything available here in England! I`ve almost finished mounting an LS1 into my Capri and have a few questions which probably seem basic to all of you. Our emissions regulations are very relaxed compared to yours(no visible smoke, hydrocarbons<1200ppm, CO2<4%, no visual checks)and I intend to run without EGR and air pump(exactly what does that do!?). Do I physically disconnect them or electronically turn them off via LS1 edit or computer reflash.

 

I physically removed the EGR pipes and disconnected the electrical connections for it. This does produce a trouble code until you disable it in the PCM. I didn't do that yet. No problems from not having it. As for the air pump, I don't have one on my LS1. I think only the california cars get those. SO can't comment.

 

If you disconnect the pipes from the EGR are you not leaving a connection hole in the exhaust manifold??

 

UK Robert you need to make block off plates for the holes. You can use the pieces you took off as a templet

 

Or, you can buy them from www.thunderracing.com pre-fabricated.

 

Thanks very much. This forum is amazing. Technical advice and response is something we lack in UK!

 

...and toothpaste.


Just kidding.

 

I bought a plug from GM over at gmpartsdirect.com. Sorry, I don't have the part number handy. It cost like $6.

 

Wow, those emissions standards are VERY relaxed.... Lucky for you guys!!

Post some pics of the install, if you have them. I'd love to see it!

 

How do I post pictures? By the way, with very little emissions gear on it(ie....none!) and no cats, what would the HP be on the otherwise standard engine? Thanks to everyone for previous advice

 

Oh, behave

Can`t upload photos - file to big(386kb) What now!!

 

Just make the picture smaller using some type of image editing software.

 

MMM... spending lots of time on photos and getting nowhere. Methinks that this is unneccessary agro!

Right then I`ll do it now while I`m at lunch at work. However don`t reply to the attached e-mail address, please communicate via forum!!

On thats clever! I`m hoping to electronically tune this engine once it`s up and running yet I can`t even upload photos....DOH!

 

First you should move that steering wheel to the other side
