you got the SR20DET to run with the Almera GTi ECU my mate said there was only a couple of differences and just one extra wire needed for the wastegate or something how did you do yours?

Well , is custom build engine , P10 Block , had oil way for turbo drilled & water ways tapped for turbo, S14 Pistons & Cranks As there stronger ,balenced bottom end, lightented N15 Flywheel & Standard N15 Gearbox, Pulsar top End with almera Temp sensors on custom housing , Compleate N15 Wiring loom used with modded injector plugs for pulsar injectors , thats about it , i have set up Turbo waste gate with mecanical valve for now but have AVCR unit to fit ,

Great little build had it rolling roaded 260 BHP with stock N15 ECU , Was Shocked

Just took her apart again to fit forged 8.0:1 pistons = More boost lol ,

So just to say dont worry with the after market route the nissan Stock Ecu is capable of running it with & few add on mods , (Air fuel Controler, mecanical /Electroninc boost control)

Great little car ,
 
cheers sunnysrule , i wana try and mount mine lower hopefully and get away with using the same exhaust , or try mounting closer to the radiator ? would it be ok losing one of the fans ? was planning on a raised bonnet to help with heat etc
also could you describe the route from filter to engine please , this is roughly how i was planning >
filter------afm-----throttlebody------charger-------re-circ--------- fmic----------plenum with re-circ feeding back in front of charger

looking at the pics from markbutts they leave throttle body in place too , maybe theres no need for me to change ? its an m45 too and it fits snugly with the standard exhaust so bonus again !

been thinkin about leaving out the fmic ? im only planning low boost so do you think id be ok ? saves on all that pipework , also with the use of a pressure switch for the 5th injector i could use water injection instead ?


what sort of running problems has it been having ?

cheers
 
my god this thread is total technical failz!

right you have an M45.. mount it where the aircon pump is us the pully.. run some pipe to an intercooler then to the throttle body then take it to horsham developments and get it mapped its that frigin simple.. the standard injectors will suport well over 200BHP the internals are the same as a 200sx anyway (rods and crank) and whoever said the rods and crank froma 200 are stronger than a pulsars are talking bollox there the same the pulsar has a different bolt pattern on the flywheel and the pulsar rods actually have bigger bearings, so are better!

you want it done cheap theres your answer fit the supercharger plum it in get it mapped youll be able to run upto 10PSI easy on stock 10:1 internals.. thats if you can get the M45 to flow enough air to maintiain 10PSi!!!

forget all your 5th injector crap were not living in 1996 and runing ford escort RS turbos the power is made from the timing and you carnt set that up correctly wihtout remapping the ECU or getting atleast a piggy back ECU..

word to ya mamas!

Damn post of the day.

People might stay away from forums to avoid stupid questions or haterz, but when wheeler dealers are pulling the wool over your eyes about this stuff, you gonna get raped.

If this Tuning bloke has supercharged an SR20DE without remapping the ECU and just using a 5th injector, I would like to see it.

And running a GTiR engine on a GTi ECU, yes it runs, and makes power but that ECU will be doing the same amount of work it did when you had 145bhp to now 260bhp....you can't put your money away on the last most important part...which is Tuning.

Please read the post correctly before slatting people please fella , 200sx rods/ Pulsar rods are stronger than standard N15 Rods & Crank ,

These sites are good buy why must we argue or put people down of our own sort , if some one has done something and it works then why argue or question the fact ? , Some people do not post because they are scared of getting slated , Thats not waht were here for Dan
 
if you read again kurt i said hes done supercharger conversions , never said once he'd done sr20de , my whole point here is ive got the hardware for peanuts and can do these bits on my drive THATS why im only intending on running low boost and using as little extra expensive goodies as possible ! i think were all aware whats needed if i was running massive boost !
my intention is a cheap safe mod using what i already have , all im asking is its limits and what i can get away with before hitting problems
thanks for the advice of the lads generally interseted
 
i think ya gonna have to get a proper remap to get it to work properly, otherwise ya could be runnin rich etc etc, i dont know much bout this kinda thing but thts my 2p, sounds interestin tho
 
the main problem im worried about is running lean , that was the only reason of using the 5th injector as it reaches higher boost , as far as im aware a re-map on standard ecu will reset if the battery ever goes flat ?

Simple fact is it works mate, in theory it should not but it dose , as for the rest of your comment it dosent make sense , Ive tuned my car it dosent need expensive after market piggy back ecus , Stock N15 ecu Dose 95% of the work , just needs tidying up around the edges, fuel controller and boost controller . 300Zx /Skyline fuel pump

The purpose of this thread is for advise on doing the job on a budjet , which ive done and it works very well , Keep things simple and its works, Start fitting aftermarket bits and problems will arise

Regards Dan
 
exactly dan , and if ur ecu handled that sort of turbo power then its gona be more than adequate to run around 6psi/200 ish bhp with my charger , im not even gona question the internals of the engine , theyle be fine , with an air/fuel ratio gauge i will be able to se if it leans off at higher boost levels , my only issue is controlling the extra fuel , how did u do it mate ? a 5th injector can be set to come in at a certain point but the amount of fuel cant really be controlled ?
what is standard bar of sr20de fpr ? is the sr20det 3.5bar + ? is it direct replacement/fitment ?
will my standard fuel pump and injectors flow ok around 200bhp with a slightly higher fuel pressure ?


also what are your views on intercooler ? i know the cooler the better but at the low boost im running is it worth the effort ?

Wouldn't call this arguing, I'd say a good debate...these type of threads are few and far between.

Yeh I read that, but why would he say a remap is a waste of money if he has never done this conversion on this engine.

Yes I see where your coming from and they are very tough engines but you will be slowly killing that engine. From my limited knowledge of ECU's controlling the ignition maps is the most important part and not just adding fuel.

Don't take any of this the wrong way, I just like to debate in threads like these...there isn't enough build threads.

hey man im not putting anyone down the lad asked for advice so i told him.. the nissan ecu is a complicated thing they dont respond well to 5th injectors ect and when its so easy to get an eprom chip installed and mapped, which will do 2 vital thing will stop detonation which will slowly kill the engine and the second will make power setting it up properly will probably be worth in the region off 20WHP..

now as for the rods again this is false almera and 200sx rods are the same they take a 17mm bearing the pulsar rods are thicker buy a few mm and they take a 19mm bearing.. also the N15 and 200sx crank are the same whilst the rnn14 crank is the odd one out...

peace
 
looks like a chip is the way to go but to be honest on this motor i think im just gona push my luck with the bits ive got , i paid peanuts for the car so ive got nothing to lose but to just put a grin on my face for a while lol should be interesting
