Another S52 swap... but this time with a newb!

plastic is good.... anyway, good work man

Just to update this thread.

Year after the swap everything mechanically was smooth.

The dyno was done about a month ago.

But today, I recently bought a Walbro GSS307 for 40 dollars brand new. My OE pump went bad so it was time for a change.

I started off with this



And ended with this



Hopefully this lasts long enough.

In general in the past year I've done the following since the completed swap:

- New Water Pump (Metal impellar)
- New s52 valve cover gasket for my s52 plastic valve cover
- New Walbro 255lph Fuel Pump
- New a/c drier for my functional a/c

The money and time for this swap was well worth it. Next is boost. =)

You need more rubber before you can think about more power. :p

Wow, I can't believe I just read 36 pages of this thread. Nice car man!!! Doing the same swap right now. Just waiting on the sensors and mounts before I actually get this thing in the car.

Was looking forward to the bolt to drive write up, mainly on the electrical side, but I imagine a year after the fact things get a little blurry. BTW what manuals did you use for your harness? Any more helpful than the other? Most of the diagrams I keep coming up with are for the 318ti.

Anyhow, as someone thats going through this right now for the first time I appreciate the write up. Always interesting to see how everyone pieces their cars together.

Do you happen to have your emmissons test papers and also are you using the pink top injectors with the stock MAF?

Pink injectors are 19lb correct? I'm planning on running these with the Stock M50 HFM. This is ok right?

Hey Sam, I used these two diagrams for the help. Some colors may not match, but I believe all pin orientations should be for the same reason.

Bare in mind, e36 vanos wire colors should all be the same, unlike the e30 engine side/body side vary within different years.




Also, these diagrams are what people already posted within this forum.

Suspension:

-Ireland Engineering Stage 3 springs
-Bilstein Sport Shocks
-Ground Control RSM
-Ireland Engineering Race Subframe Bushings
-Ireland Engineering Polyurethane Trail Arm Bushings
-Treehouse Front Control Arm Bushings

Still need to buy sways and Coil-overs.

Pink top injectors (m52/s52) are 21lb injectors. Running them with the stock 3" hfm should be fine as obd1 95 m3s from the lot came with 3" hfms, and so did m52/s52s.

Do you happen to have your emmissons test papers and also are you using the pink top injectors with the stock MAF?

I have my emissions test papers. I could scan it. The setup I used for the smog is the exact setup I have.

obd1 s52 with 24lb TMS Injectors, 3.5" HFM (540i/740i obd1), Silver Label 413 with Chuck&Stickley Chip for mentioned mods, Obd2 headers, 1998 obd2 m3 midpipes, custom catback. Passed pretty easily.

Let me scan the papers with some editing of course.

Hey thanks! I about to pick up some obd2 midpipes so I hope I can pass now. Thanks again.

As long as the catalysts are still good on the midpipes you should be fine. Here's the test.

[e30s52]

Did they make you do a test at idle too?

[jahnaboi]

There is no idle test.

[e30s52]

There is no idle test.

Alright thanks! I asked because Wa has a at idle test.

[jahnaboi]

I see. Pretty sure if you let your cats warm up enough you will still be fine. Where are you getting it smog at? Wa?

Yes, I have to pass so I can get my tabs but I guess I can pay some shop 150 bucks for a waiver but then they will know I dont have a m20 anymore.
