Dinan S52 swap confusion

[bimmers1]

Hey guys, I have an interesting scenerio that I havent been able to find all the info for. I have a 6/95 Ti that im doing a swap on. The donor engine is from a 6/99 Mroadster 5spd with a Dinan supercharger (vortech)thats going to stay with the motor. Couple things that im not sure on how to handle if anyone could shed some light it would be much appreciated. 1) The harness on the Ti has one 20 pin round connector; the Mroadster motor has the 20 pin round connector as usual but also has a 12 pin round right next to it that carries a variety of things: slip control or (choke valve for intake), tank press. sensor, two wires to the cluster, DLC power, Charcoal filter shutoff valve and DME date to DLC. My question: is there a way to do this cleanly or what are my options, keeping in mind the vortech charger has its own boost control that is wired into the Mroadster harness. I know this seems like a lot of info and I hope I was clear but this is a mess, can anyone help please?

simply put...
you need the donor harness (M roadster), the Ti harness is for the M42...not to mention that your Ti is a 95' and the donor is a 99', going from an OBDI car to OBDII car/engine as well...
Engine + Harness + DME + EWS + Cluster should make for an easier job with less headaches... and if you have the donor car, I would do a complete rear end swap as well, since it's coming from an M roadster. Good Luck with your project, it sounds like it'll be one quick son of a gun!...

Definately agree with swapping the rear end swap, but I just found out that this will be a daily driver, thus it must pass MO state emissions. Im wondering if there is a chip or software that would delete the secondary air and possibly the tank leak diagnosis pump. LOL the car will be quick for sure however the swap doesnt seem like it will be so quick. Thanks

Cool.

You are ambitious!

Good luck.

As I stated previously... You are going from an OBDI car to an OBDII engine. There are NO chips for OBDII, only DME/Computer Re-programing or Flashing.
The rear end swap will be a must for the Ti to handle all of that power. Most Ti's are open Diff plus the shafts are skinny... The swap will give you the proper final drive with the LSD diff and heftier shafts with the added brake upgrade. I should point out that the front M roadster brakes will be needed as well to stop that power!
This of course if you have the donor car at hand, if not you have a long road ahead, because you will need lots of parts from it to complete the swap and have a working vehicle.
I myself have no experience swapping, but I have read and followed others on this board to know it's not as simple as it looks... even from cars of the same year, not to mention OBDI to OBDII.

Sorry guys, it just occured to me since the Ti is a 5/95 there is no need for it to go in for emissions. Also I feel inclined to tell everyone I am doing this for a customer and is not my personal vehicle, I really wish it was though Now to figure out how to make the wiring look pretty. Ill try to get some pics up soon.

I would only attempt this with the complete front OBDII harness.

You can always fool the ECU flash etc, but the harness makes all the engine accessories work, and some are more important than others.

Is the customer aware that without all the gear the car is not really legal?
Cause if he ever sells it and the buyer tries to smog it it can get ugly....

It is possible to write out the secondary air pump, Technique Tuning and Active Autowerks have done it, not sure how that meshes with your Supercharger though. GL.

Simply put, dinan reflash for the supercharger, SAP Simulator, possibly o2 sims, ews delete, ews cut to the chassis if it still looks for it, and a cluster.

and some driver classes

Well gentlemen I have the Mroadster rear carrier in as of today I swapped over the hydraulic brake lines and ebrake cables from the ti as well. I had to weld on some studs on the control arms for the brake line holders cause the roadster control arms didnt have them. oddly enough i found out the hard way that as far as i can tell the roadster rear hubs are farther apart L to R than the Ti hubs thus the ebrake cables are about an inch too short when i put them into all three holders so I will be welding two more studs (one on each side) to the brake hose/line mounting point to give me enough effective length to insert the ebrake cable into the body. Sorry about no pics yet I thought i could transfer from my phone but my phone didnt agree. Ill be bringing my new digital to work now. PS. Yes the customer is aware of the anti smog campaign im about to unleash on it , I do have the entire harness free of any damage, its still hooked to the motor along with the DME. THanks for the input everyone, im sure ill need more along the way.

Was able to email some photos from my phone to myself so here are a couple of starter ones just from the past couple days, more and better ones one the way! Looking at them side by side.

The poor roadster donor

Are you doing any body work to the rear of the ti so the roadster rear wheels fit?

[M-technik-3]

Big task for you as a shop if you not aware of what all is entailed. One of you will be loosing their shirt tails on hours billed.

Me, I would have converted the S52 to an OBD I engine and ran it with an OBD I wiring harness and had a proper chip burnt for it. Going OBD I would allow you to use the M/S50 manifold which is larger.

The supercharger/s52 combo OBD I set up should be good for about 320 hp depending on trim of SC and ECU setup.

[bimmers1]

As of right now no body work is in order, right now the goal is to get the chassis right and the drivetrain complete. Funny m-tech should mention it but I dont plan on making hours, this seemed like a rare opportunity for everyone involved. Also right now as it sits the roadster was dyno'd at 368hp at the wheels so since it has the same drivetrain I imagine it will be close to that. The harness as of right now no plan on making it obd1 but who knows what could happen. I read on some other threads that jim has a guide that has lots of info of obd2 swaps, how do you get ahold of one of these? Sleepy so im off to bed.
