itsLeon Posted September 27, 2019 Share Posted September 27, 2019 (edited) 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 Edited September 27, 2019 by itsLeon 7 Quote Link to comment Share on other sites More sharing options...
RobPhoboS Posted September 27, 2019 Share Posted September 27, 2019 Nice one, I'm ordering my last bits and pieces too very, very soon! Would you be able to PM or post up you compression/leak down results ? Quote Link to comment Share on other sites More sharing options...

I will keep following your post as its always fun to read what other people are doing on the hard way of NA power. And just to make you a little more envious of the workshop. Yes we have our own dyno 4 Quote Link to comment Share on other sites More sharing options...

Out of interest I read you’re mapping it yourself, are you using UpRev or changing ecu? Gonna change ECU just to make things easier and the fact i can get it from a friend (he's almost a collector of ECU's :P ) Also if we tune a stock ECU we don't use UpRev but romraider while its more limited then UpRev for most tuning its more then enough (bolt on NA tuning, pops and bangs, removing of limiters rpm or speed) and the best part its open-source! So no need of expensive licenses. What are you planning todo? Changing ECU or UpRev? Edited October 3, 2019 by itsLeon Quote Link to comment Share on other sites More sharing options...

RobPhoboS Posted October 4, 2019 Share Posted October 4, 2019 I'll be pulling my one apart soon too, just need to collect a 2nd car next weekend (hopefully) to run around whilst this happens. So there are at least 3 n/a builds happening on the forum now Quote Link to comment Share on other sites More sharing options...

It'll be good for winter driving, just to get to the gym and see family. I should be good to start around the end of the month, all being well !

Im currently balancing the connecting rods and waiting on the last bolt to come in (was missing a ARP connecting rod bolt). 1 Quote Link to comment Share on other sites More sharing options...

Edited: I just found out what a Syvecs is and my god they are expensive! Sadly good and expensive always seem to come together! I’ll need 100% convincing it’ll deliver what I want it to. It’s also in the queue after a few other bits......one big one being full manifold back custom track day friendly exhaust so it won’t be arriving anytime soon.........plus I’ve got the engine to build first.

Have it in the car in Januari and tune the car in februari. So many other projects also coming in so don't have all the time to build Quote Link to comment Share on other sites More sharing options...

Yeah im eager to. Tonight i will be working on balancing the connecting rods and the last missing bold came in. But i also have to get a car of the dyno and drive to gas station because its out of fuel and trying to make a ghost cam tune on a stock ECU without uprev. 1 Quote Link to comment Share on other sites More sharing options...

Me and my friend will be taking a couple of days off in the beginning of november to finish the engine building so we expect to start tuning the car on the dyno around december.

itsLeon Posted October 16, 2019 Author Share Posted October 16, 2019 Small update: Tried to balance the connecting rods within a 0.1 gram and failed (need some special equipment) now gonna try to balance the connecting rods and pistons so the combination of those 2 are the same. Also balance them around the cilinders so that the weight is not only on one side. 1 Quote Link to comment Share on other sites More sharing options...
itsLeon Posted October 22, 2019 Author Share Posted October 22, 2019 New update: Balancing of the rods and pistons are done Gapping the pistons rings are done Fitting all the rings are done Then we found out the connecting rods don't fit the pistons... Well that sucks (small end is to wide of the rod) Anyone interested in pauter rods? 2 Quote Link to comment Share on other sites More sharing options...
