That sounds like a fun project too! Keep us posted on your rebuild!

Yes, we used the 999s┤s showerinjectors and they are now controlled by the a custom chip by Tom using the 748R┤s stock 16M ECU.

And that is the smartest decision you could have made.

Not really.. We used the 999s -04 throttle bodies that came with our engine. That has the non-linear TPS unlik the linear tps of the 748R, but tomtom reprogrammed the chip used to take the input from the 999s stock TPS. So we are running 999s throttlebodies but using the 16m ECU.

amullo 1. Engine management. 998? xx9? 16M? Obviously, if there were a 16M program, that would be the easiest, b/c it wouldn't involve changing/hacking harnesses, etc.
We used the stock 748R harness. ALL of it.. No hacking or slashing anything. We also used the 16m stock 748R computer with a custom chip made up by tomtom (member here on the board). He has the all the specs saved, so he should be able to burn a chip for a decent price.

2. Throttle bodies. This is dictated by what engine management is used.

3. Frame. This is affected by engine management and throttle bodies. Aparently, coils need to be relocated in any case.
Correct. we used the stock 748R coils after we tried using 999 coils. The 999 coils would have been better, but we never really got around the problem of the signal input to them. We ended up just zip-tying the 748r coils inplace where the 998┤s have theres.
The frame itself was a stock -00 748R frame.

4. Airbox. Still haven't seen one working on anything other than a 748R/998.
We hacked/slashed our own airbox together, using the 999 lower airbox together with the 748R top part. You can use a 998 airbox instead, they still sell them in fiberglass and CF for pretty cheap bucks.

5. Swingarm. Any mods necessary for SSSA to fit XX9 engine?
Nope. Ours bolted straight onto the -04 999s engine.

6. Exhaust. 998 Systems are pretty rare. Are there ways of adapting other systems to fit, or do you have to sped $3k on a full system?
We used an Akrapovic 60mm full system that one of our team had laying in the garage from his old 996R

Hope that answers some bits.. Our 999s -04 engine is completely stock save for some camtiming and setting the squish and a full mapping of both ignitionmap and fuelmap incl. offset. It chucks out 140+ RWHP SAE and pulls away from earlier R1┤s on the straights.

I'm a little surprised that there's no kit to do the conversion for the most common configuration- 16M computer and strada/bip frame. I'd pay decent $$$ for a chip, airbox, headpipes, and throttle body linkages that would make the conversion a painless, no-head-scratching process.
1. engine management- this will probably depend on wether or not the 998 engne you source comes with a harness and ecu, if not i beleive you can use the 916 harness (with apropriate 998 connectors spliced in) and have a chip mapped for an apropriate fuel curve. remember an engine is essentially an air pump, as long as it gets air fuel and spark it dosent care about anything else. finding someone who can tune it is on you.

2. throttle bodies- the 998 throttle bodies will have to be used unless your going to have some custom intakes made as the desmoquattro intakes will not fit on a 998.

3. frame- working around the cross brace in the frame, relocating the coils and sleeving the engine bolts (instead of drilling the 916 frame) are very easy and straight forward.

4. airbox- probably the most time consuming part of the swap, this entails taking the bottom end of a 998 airbox, cutting and mating it to the top rim of a desmoquattro air box. lots of epoxy, lots of patence and it is very doable.

5. swing arm- the swing arm is a direct bolt on, no modifications needed.

6. exhaust- the way im going to do the exhaust is use stock 998 head pipes (ebay) with a slip-on termi system, to keep the cost down a bit.

all of this is simply info i have gathered from others posting on this forum about there swap, it has been done quite a few times and a few members have posted pictures, surprised they havnt chimed in yet.

But since going testastretta, NO issues at all.


//amullo
i don't no if you are crazy or brave...

i have broken my SPS engine with big bore, perfect timing, cylinder head "drill" ( i don't know the correct word but 35 hour's work for each cylinder head...), 54mm arrow full exhaust, power commander setting, big carbon airbox and new 520 sprocket chain : 145.8 rwhp...











At this time i said the desmoquattro's engine, it's over...

And my 998s engine makes better with only big bore, perfect timing, power commander setting, 54mm termignoni full exhaust and old spocket chain : 149.21 rwhp...




And i love make surprises at 1098 track's owners mith my "old 998SPS"...

thats because he said nothing about this conversion starting with a 998/748R frame holding its value better, witch was my main problem with your point of view. yes those frames would be easier to use because you dont have to deal with a few modifications like you do with the 916 frame,, but those of us with ailing 916s dont have 998 or 748R frames.
