i got an s5 turbo swap for my 88 n/a and when i got the motor, the omp lines were all broken. along with every other hose on that engine. if anybody can tell me where to get these hoses, esp the omp injector lines cause i cant find them anywhere, please tell me. thanks in advance!

Look around at Mazdatrix - Oil Injection Parts

They also have a lot of the other various hoses plus a ton of other parts. They are a bit pricey but they are a good source for Mazda parts.

The OMP lines can also be built out of plastic line and the fittings for much less thanm the cost of the Mazda OEM lines.

Search around on here for OMP Line Rebuild or something.....


Also most of the other hoses like fuel, vacuum and heater hoses can all be replaced with regular hose from the local auto stores...

 

You can make/bend your own using brake hard lines. I did this, and have been very pleased with the results. You can braze the original fittings on each end.

now what do you mean braze? how exactly does that work with the brake lines? i like that idea cause after my rebuild and port, which i have to drive my car down to j&r auto in long island on the 5th of july, i wanted to do like a stainless steel braided line for everything possible. i dont know why i like it so much, its appealing.

 

There is an excellent DIY on this forum detailing how to do this yourself. Includes great step-by-step instructions and part information. Do a search for "Rebuilding the OMP oil injection lines" and check it out.

Edit: Here ya go. I did it for you.

DIY is the way to go.

 

thanks GO48! im gonna get started on this tomorrow!

 

You're welcome. Since you will have the UIM off to do the MOP line replacements, might as well pull the injectors and have them professionally cleaned, refurbished and tested. There are a couple of reputable people who do that for a fairly reasonable price. One that I have had good experience with is http://www.cruzinperformance.com/.

Make sure to replace all the UIM gaskets.

 

yea, sounds like a plan. i need every gasket actually. i bought this engine doing a Tii swap and found out it was an s5. and i was getting ready to have it rebuilt and street ported but i ran into all these problems. so i was like eff it, get it running right, then get the port. so then i ran into this other problem. my 7 is an 88. i need an s5 front harness. any ideas?

 

Look on eBay. If nothing is listed, contact one of the regular eBay parts sellers. There are a handful of sellers that have fairly large collections of parts.

 

nice will do, thanks alot again!

 

Thats what i just did and am very happy with the results.

 

Oh wow, thanks.
