i was wondering if anybody knows how to tune the timing in a turbo neon? like how many degrees advanced or retarted is best for turbo applications?

and also how big of fuel injectors should i run if i plan on running 10 p.s.i or 25 p.s.i.?

 

10 psi or 25psi is a pretty big difference

 

get some 32lb injectors for anything up to 15psi, above that, go with the highest you can find. as far as timing goes, USUALLY, 10-13* retarded is good, seeon some that have been way past that, and some that have been set at 0. what are you using for your timing? adj gear(s) or msd or MS?

***edit*** 32lb injectors will be plenty for the 15psi, you can take fuel out, but you cant add, lol. you could always go bigger and take fuel out as well. 36 would be an all around good choice, and then just take fuel away as needed.

 

i was wondering aobut this kit http://www.howellautomotive.com/inde...ROD&ProdID=383 with the 040 over bore good or no? which pistons should I go with that would work with my turbo? 8.6 10.5 or 12.5???

 

8.6:1

the lower the compression, the better( for turboed engines only)

 

what about the stroker kit? im pretty sure the pistons and rods are good what about the crank? whats the diffrence bettween the non forged crank and a forged crank? i would think that the forged one is stronger

yah i know my whole engine can handle 25 p.s.i. the block has been blueprinted and bored over. and the whole engine is balanced. my bottom end has a stock lightened shaft, eagle rods, wiseco 8.8:1 comp. pistons and plus i have a custom ground camshaft and oversized rods with springs to match to hopefully take care of valve float. so if i used a AEM adjustable camshaft gear with a mopar performance pcm would i still need to retard timing by 10 degrees?

 

i was told that the mopar ecu and turbo's dont like each other, that the ecu has too much timing and you cant compensate for it. thats just what i have been told, thats why i am selling mine.

 

good thing i log onto here before i buy stuff lol. i know the mopar pcm "greatly advances timing" in there sales pitch. so if im trying to retard the timing and advance it im just asking for trouble lookes like. what performance pcm would you suggest? or should i leave it stock?

 

the stock crank can handle up to 600hp..the forged one is stronger...but its pricy.
