[turbocorolla]

hi guys,im in the process of building a ca18det engine for my daily driver. stock bottom end,t3/t4 turbo from M.I.C.boost should be around 20-23 psifor now stock throtlle body,720cc injectors from RC enginering,engine management is going to be microtech(fuel&timing)here on the island we dont have a dynoshop(yet),how much HP is this engine going to make??????i think around 300hp?what else do you guys recomend me?is the stock bottom end capable of this abuse?shave any of you guys already use the microtech on this ca18det engine ?,and what are your remarks/pros and cons of this?????any help is appreciated

come on guys!!!!!! no help here?????boost boy???any one???

Yes it will get you well over 300 whp. And yes the stock bottom end can take it. Boost Boy made something like 312 whp on his sentra with a t3t4 and a sds system (untuned) at only 18 psi.

thnx for replying,do you prefer me to use the sds engine management???i was thinking about it before i choose the microtech system!!!now i think ill switch to sds ,so you guys can help me out with the fuel and timing maps!and wich system you recomend me to use from sds?

Using a T3/T4, a standalone and a set of 720cc injectors would definitely get you above the 300whp mark granted tuning is up to par. I have a couple of friends with microtec computers, but neither one has installed it yet. One has 240sx with CA18DET and the other a 3rd gen RX-7 (whom I've smoked already). Stock bottom ends of CA18's can normally withstand some thrashing, but unless you rebuilt your engine, there's no telling how much hell that engine has been through unless you pull the oil pan. If you decide to use the SDS, just ask myself or Drumma022 who is also using 720c injectors as well as an SDS.

How much were those 720cc injectors and wheres a good place to buy injectors from. I leaning towards 550's but if 720's arent that much more then count me in.

[turbocorolla]

so i should "dump" the 6al and buy a dis-2?do you know any one thats using microtech on their ca18det??ive read that the sds cant datalog and you always have to write down the changes youve made to the maps, is this true?

Once you've tuned your car for optimium street performance, you're basically in the relm of turning up the boost and changing basic parameters to assist in running high boost. It's called SDS (simple digital systems) for a reason and it's simple enough if you have a basic understanding of formulas and the characteristics of the motor you're using. Like I stated before, I have a friend that's has a microtech on his 240sx with CA18DET, but I have yet to see the thing run.

can you keep me posted onyour friends progress???since i wont buy my microtech till the end of this month(july)
