After reading a couple of builds here including that of @350Butcher i thought time to start my own thread.
First of all some pics of my car. Hate it or love it.
Why the NA build?
Well my engine started to have problems (very low compression test, lose of power) and after helping out friends with their turbo or supercharger projects i wanted something else.
The idea was to go simple and not to go to wild (replace gaskets, different cams, other intake).
But after swapping the engine i got from a friend of mine (he had one in reserve) things started rolling.
A friend of mine ( @Hansburger ) told me that he knew a shop selling some engine upgrade parts for a 350z and after talking to that shop i bought their parts for cheap, like real cheap.
I bought the following items:
- new 350z short block
- Pauter connecting rods (major overkill)
- wiseco pistons 8.8:1 (sold those and bought new £600 Cosworth 11:1 pistons with rings)
- lightly used heads
- lightly used crankshaft
- other minor parts
Well i still wanted different cams because why not and i was looking at the JWT C8 but then i found out a seller near mine location was selling some proper race cams for 1/3 the price of a JWT set. So now im the owner of some 294 duration 12mm lift cams... ow boy.
At this point i was like 'Yeah lets just go full retard and see how far we can go'.
Ordered some parts in Amerika, like gaskets, studs, new rev-up oil pomp (i want to rev higher), etc
So at this point all the parts i needed where in and time to start fitting but we ran into a small problem. The cams didnt fit.
After contacting the manufacture they told us that we needed so special parts to lift the buckets and ofcourse heavy springs.
Right now we can start building!
measuring the weight of the pistons
Setting up the block
Re-measure all the clearances (had a local shop do this first for ordering the correct parts)
But like any other NA build you need a better intake and better exhaust.
So for the intake i have a kinetix high velocity, 75mm throttle body and need to create a custom 3.5 or 4 inch intake tube.
For the exhaust i have bought from Torqen the ISR longtube headers and this will be connected to custom exhaust.
So the goal for now
- 8000 revs.
- lots of noise
- dont care about the horsepower (but a little more then 300whp would be nice)
- Tune it myself
Up next:
- weighing of connecting rods and see what connecting rod and piston go together.
- Assemble short block
