if your going to leave the stock internals don't go crazy and run to much boost if you want the car to last i would say don't run more than 8-10 lbs, also make sure you check your chain tensioners for major wear, i just built my KA this past winter so if you got any questions let me know

why do people insist on saying you can ONLY BOOST A STOC KA TO 8PSI

nissanfanatic made 350whp for like 3 years on a stock head/block......

stock even took him to 53Xwhp

a GOOD tune and proper fuel and a ka can make big power for ever, keep oil fresh and rock out. Orion made over 300whp for over 3years too IIRC.

op please search this is all over the place

^^ +1.

IMO 350 hp is a perfectly safe HP level on a properly tuned Ka. Its been done time and time again.

yeah the stock ECU with a apexi SAFC(i think thats the name) is that pretty much the only computer tunning stuff ill need? ive heard people say if u go turbo get a Z32 MAF sensor is that right? or is the factory KA one fine?and do yall know of some websites i can check out to get information on different sized turbos and other stuff like that?

Read, read, read.

The engine build is part 7 or 8.

15 psi, no issues at all.

well i was looking thru the KA-T.org forums and found this

Average: 300 rwhp to 350 rwhp, you have to start to expect a little more lag. This is about the perfect "street car" limit. No race gas, just good honest street car fun that is fully capable of bring home a 12 second timeslip on a good run.

Turbo Manifold T3/T04E .50 Trim compressor, .60 trim compressor housing / Stg 3 (aka TA31) turbine wheel, .48 to .63 A/R exhaust housing. Internal wastegate optional but not recommended. Downpipe can still be 2.5", but this is as far as I would want to push that. Front Mount Intercooler (FMIC) It's time to upgrade to a larger front mount as the larger will push more air than the smaller sidemount can cool.

Fuel Control 550cc Injectors SAFC2 to control your fuel injectors, along with the stock ecu. MSD BTM At this stage I would be running the BTM to control timing retard. Reflashed ECU-This can be a DIY thing with Megasquirt Tuning or a JWT. Z32 Maf is required, as the stock Maf stops being able to read at around 260 rwhp. Wideband O2 Sensor should be installed for tuning.

Block Internals This is where I would start to consider it necessary to replace you pistons.

is that a pretty good example to follow and maybe go a lil further with maybe a full 3inch downpipe and exhuast and stuff like that?

heh i was going off that too when i turbo. i would get an exhaust anyway but thats me

[samuraijesuss13]

yeah i plan on getting or at least trying to get an HKS Hi power exhaust and a 3 inch downpipe

[samuraijesuss13]

woo got both manifolds off cams out tomarrow im taking the head off pistons and crankshaft then ima start looking for a shop to send the head and block to to have hot tanked and decked if they need it.....then i order parts and get the rebuild under way!!!!!!!!!! oh and mine is an OBDI doesnt have the secondaries wich means its a 95 model KA if im not mistaken.........but yeah what exactly are all of the vacume stuff on the back and what all can be romoved without harm to the engien if anyone knows?
