Hi guys, I'm looking into building a Westfield and current preference is the S2000.

I've searched the forum and found a few bits relating to my query but no definitive answer as yet.......

Now the Omex TB kit is out does that mean that post 2006 fly by wire engines are an easy option for this build? I've seen people thought maybe it would but are there any hard facts on this now?

Thanks, James

It's my shallow understanding that it should work. If using the AP2 engine you might need a different tune from OMEX due to it being a 2.2L and not a 2.0L.

If I were in your shoes I'd call OMEX and get the straight scoop on it to be 100% sure.

I have an S2000 with the AP1 engine and OMEX ITB's and the car is wonderful. Very quick, it makes all the right sounds and handles just right.

We don't have the 2.2 in the U.K. Dave, ours is a modified 2.0

@IanK did a bit of digging on this, last year, I think, with the parts guy at his localHonda dealer. (Was a bit limited how much of the guy's time could be used up, and if I recall, this was just going by part numbers.)

Nothing insurmountable was found, but not as easy as had been hinted at on Honda forums. But that may just be down to our use of the Omex ecu.

Apart from the obvious, inlet manifold, idle control valve, throttle body etc. I believe Ian also identified that different trigger wheels/patterns were used, I can't recall now if it was cams, or crank or both that were different, but certainly, for use with the Omex ecu, they'd need to match the  pre DBW engine, as those elements are "set in stone" on the Omex S2000 ecu.*

*Not 100% true, but would require them to develop a new version for the different trigger wheels, which to my understanding was  outside the remit of the 630 type S2000 ecu we use.

However, if you used an ecu that was compatible, then it would be much more straightforward. Might even be worth checking if the Omex 710 series was, then existing mapping may carry over, with a few tweaks?

Just looked at Lings Honda spares and indeed there is a different part number for a 2000 yr engine to a later 2006 yr engine .

Hi James, as @Dave Eastwood (Gadgetman) - Club Secretary says, I've looked into this and its 'should' be possible. Are you planning on the Omex ECU via WSC? If so, talk to Mark Walker at the factory as I spoke to him at Stoneleigh and he's also been doing some work on this. 

From memory the crank trigger wheel, sensor and loom plug will need to be changed. There may be other items too, however it would be great to know as pre 2004 engines are clearly getting older and rarer!

Thanks for the replies guys.

Ian, my preference would be to go with the WSC Omex ecu but if not possible I'm not adverse to going for a different one and doing the whole hog. I've had cars on itb's before but never done by myself so suddenly the thought of it all is daunting and I want to make sure I do all my homework before committing to anything.

Ive not ruled out a BEC or a well prepared duratec or similar either but the s2000 route seems more cost effective.

If I did go pre FBW s2000 and eventually the engine gave up are there any places that can still rebuild these motors?

A looked after F20C does seem to last quite well, and in the much lighter Westfield chassis, "using the performance" won't put as much load on the engine as the donor car did.

There are people who can rebuild them, though it's something that you'd need to research as and when. The difficult bit really, seems to be the bores, providing you can avoid doing anything with those, then it's just a case of dealing with an engine with high precision tolerances. The bores are tricky and a specialist area. It's a while since I looked, but from what I recall, it seems to be case of re-lingering them and then reboring/honing as necessary and accepting that they won't be quite the same as original Honda bores. But again, in our application, providing it was done to a high standard and the correct liners used, I don't think it would really be an issue.

Have a look at Emerald ecu's. They do an S2000 ecu . They may already have this later set up on their system.

OK, see my other thread here for more details.

But essentially, Omex have now done a throttle body conversion on an originally drive by wire engine.

The ecu itself can be configured for the new DBW trigger wheels on the cam and crank. This can be done retrospectively too, for existing owners.

Note, some of the connectors are different, so will need raiding off the new engines loom and either swapping on to your existing Mega S2000 ecu loom, or incorporating into a new one.

I also must stress, this is part of a conversion to Omex individual throttle bodies, so does not retain the original drive by wire set up in any way.

What it does do, is suddenly open up a whole raft more of engines available to us, that are newer and potentially lower mileage.
