hello guys

I want to share my build with you if somone interested in doing a motor swap in any chassis this thread will help a little
so it all started when my bimmer blew coolant hose on m52 engine so i ve decided to just throw all bimmer problems away and start a new swap with something reliable so most fav option doing engine swaps in an e30 is s54 engine from e46 m3 it makes around 330 hp on engine and thats the last good thing about it .
2nd thing i hate about that engine is its the heaviest 6 cylinder you can buy . Iron block around 500lbs with all accessories and also the parts are very expensive for example . Intakes for that motor starts around 500 dollars and goes upto 2500 dollars just for a intake which will give you only 10+ hp and thats it .

.. So i decided not to go that route and find something else . I started searching the best 6 cylinder in the market because of class rules in track racing and auto x .. the rule is if you're engine is under 3.8 litter its a different class . If its over 3.8 its a v8 class ..
so i can choose the engine with maximum cc of 3700 .. so i came o cross a vq37 motor with a accident chassis from rear and guess what it was a nismo 370z 2013 and engine was like a brand new ..

so i ve decided to buy that motor and leave everything else on the wiring guys to do the swap and trust me that was the start of my problems . So i started the swap and sent the car to my friend at auto one performance garage @ on instagram ..this guy can swap anything in any chassis for example now he,s doing a Ls swap in a fisker karma 😂 so you can imagine the madness .. also his most famous work is renault clio with a rear wheel drive conversion with a Ls swap engine on the front and single turbo on it

..so we started with the motor mounts and it was a easy task because of e30 engine bays which can take even a v12 in it ..After that transmission which is very long but it bolts right up on e30 because the shifter hole place up right on where it needed to be ..so not cutting needed for a new shifter .. custom driveshaft and some hammering the firewall because the bellhousing is little big .

. the engine is tall but narrow and small compared to m52 inline six so it saved us lots of engine bay space and you can see in the pictures how much space i have between the radiator and the engine and also the engine is sitting behind the wheels compared to the inline six touching the radiator

the last part ...wiring .. what a nightmare of a wiring nissan made .. lots of small computers and systems inside the cabin which needed to be removed and wiring needs lots of cutting and whatever we tried nothing worked because of immobilizer not letting the car start even after nats delete we did from uprev tuners ... The problem is on these engines ..vvel motor and ecu which runs the 2 motors on each bank .. vvel module controls the throttle on each bank so if your vvel module is not working it will not let the throttles work so you ll start the engine but you cannot rev the motor .. so we took out the vvel ecu from junkyard and swaped it to my car and still not working .. thn we found out that if vvel module is from another car and ecu from other ..it will not work ..you need to take a matching pair from a donor car .. vvel module and ecu should match ... In the end lots of testing with new ecu,s and wiring no luck ..so we ordered a new wiring .... New ecu ..new vvel module from america and sent it to hexagarage which can delete all the extra stuff and make it a standalone wiring and ecu ..so he shipped everything back to midleast and finally the engine started but with some problems .. throttle not working because vvel codes it was throwing i think it was p1090 and p1092 which was vvel motor not working and same problem as before vvel module not working .. in the end we found out the it needs seperate ground wire directly from a battery which gives it full amps and thn vvel will work .. so it started and first time in a year throttle worked and revs upto 7k .. and with a uprev tuning we had to turn off all the extra sensors ..abs ..tcs ...ecs .. airbags .. limp modes etc etc .. in the end engine is sitting 2 inch taller thn the fenders so my hood wont close fully so added some spacers in the hood and works fine . The brake booster is pretty big on e30s so needed to a small one and removed the one from nissan patrol suv clutch booster .. yess this suv comes with a clutch booster and its around 4 inches of diamter... after that took to dyno tune and it made 360hp on engine Its pretty good numbers with shorty intakes and shorty headers and dual 2.5 inch exhaust with a hamman bmw muffler .. driving experiance .. car is really fast like it lifts up the front on wide open throttle and on track and autox no lag on tight corners because of N/A and i ve seen all the turbo cars struggles on autox so am happy with the decission to keep it NA ... Never lost a race to anyone since the swap .. did some runs with srt8 chargers .. 5.0 mustang .. porche 718 spyder .. amg 63 .. list is long .. if you're interested more about this build do follow my id assasin_e30 on instagram
