So is this SX convoy on or what??

Ah sh!t u guys, I so wish i lived in jhb, I wud so be in with the whole convoy thing as well as the A1.

I hate Cape Town sometimes. 🙁

Freddie how is the SX going??

Well, thanks for asking. One or two lifters still dancing. Severe oil leak back engine crankshaft between gbox and engine. And then since last week, I noticed some puffing white smoke at start while idling. Still need to watch it longer to say what is happening. Still running on closed boost like 0.5. About 3000 kilos on the clock. I will get to all these, budget permitted as always.

Well, well, well. I lovveee my sx again. Must be something between 5 and 10 000 kilos done. I am ready to dyno! Budget permitted end of march 2008. Oil leaks? What oil leaks? Nada. Dancing noisy lifters - yes slightly so. That is OK. Will replace the freeking lifters one day. VC Idle route and dustbin policy works just great. Coil packs replacement next on the list. The sx needs new tekkies tho. And Ero ---- turbo gone??? Nooooooo, don't think so. Well just not yet. 😂 😂 😂

BTW: Scorpions don't forget. Who said : "And he cant even get his own sx running? 😈 😈

Thats cool Freddy, is that now with the Diesel oil?

Glad to hear that your happy with the ride again.

Hey Chem!

Just read your whole thread! Damn man! 😮 😮
You went through all this and you still prevailed! Nice!

Oh and I'm glad your love for the SX is restored again!

Just one more thing... are you running the t28 now? what mods do you need to bolt it to the standard ca18? Oh and is it possible to run it of the stock ecu?

Sorry for all the questions 😳

Cheers Riekert

Thanks, Riekert.
No problems.
Yes it is about a t28. Bolt on std No issues with that. .64 exh housing. Stock ecu is fine with it, altho I use a unichip.

Riekert, I like to stress that I always had the assistance of one or two of the club members with me, while the rebuild was on. Thanks to them again.
Here are some pics of the engine bay, just after the modification done on all idle control pipies removed,

Ah thats cool, was also thinking of doing that t28 mod...

See thats way I'm asking... with guys like you, VC, Vlade and all the rest you can't go wrong....

Do u have dual w/m injectors there Chem 8) ? If they are both w/m injectors, what is the purpose of spreading them out like that? Like having one by the turbo and one by the throttle body?

Love the look of your engine bay with all the red piping btw 🙂

I think it cools the air at the turbo and then just before the intake thus forcing in more air?

Yes, it is dual. The one close to the turbo is a bigger nozzle, and the nozzle close to the tb is smaller in spray pattern. Keep in mind I don't use fmic, When you use fmic, this dual set up would be unnecessary. One nozzle would then be fine.
The choice of nozzle sizes in this set up is paramount. To prevent quenching: In my case the bigger nozzle is 225 ml/min and tb nozzlle 60 ml/min.

I still need to replace the tb nozzle down to 60 ml/min. Currently running a 175ml/min, which I get the gut feeling is slightly to big.

A possibility is then to reduce the pump pressure, but I dont like that.

So, would I be correct in saying that the dual setup is to prevent the temperature dropping too rapidly and having adverse effects on the metal piping?

And then with an intercooler this isn't needed as the temperature has been lowered some what by the intercooler before hand.

Perfect.

Cool thx! 🙂

So it would be a wise choice to go for fmic and w/m?

w/m and an intercooler do the same thing (well in terms of cooling the intake charge that is) and the effects will compound. So, ya I'd say its a good idea. But as Chem :cool: has shown u don't necessarily hava to have an intercooler. w/m could do the job just fine if need be.

You have missed something important about w/m, which fmic cant do? To cool the combustion and up the octane, thereby allowing the timing to be advanced and prevent detonation.

Ya, thats the big advantage of a w\m system. I guess I shld have mentioned that.
