Andre3000 55 Report post Posted June 9, 2009 (edited) Okay, basically theres a sh*t load of people telling me to do different things to achieve 2.8 in my m20 and im going crazy. 1. I dont know much about the vanos system at all, so i need some explaining done. 2. Alloy block m52? - bad?good? what are my limitations? 3. I really want an s52 but cant find one, so if anyone can point me in the direction of someone willing to part with it that would be great. edit: sorry meant s50, european m3 engine Edited June 10, 2009 by André3000 Quote Share this post Link to post Share on other sites
westy 614 Report post Posted June 9, 2009 E36 M52 Vanos is a simple switch on/off system. Works on the intake cam only (advances/retards it). Alloy block not as strong as iron but fine for a modest powered road car. S52 is a US only engine for their M3 Evo. 3.2 litre version of their M52. Theres a big old sticky here that tells you heaps about fitting the M52 to an E30. Quote Share this post Link to post Share on other sites
hybrid 1044 Report post Posted June 10, 2009 the s52 isn't a real engine .. all though the yanks would want you to believe it is Quote Share this post Link to post Share on other sites
mr E34 11 Report post Posted June 10, 2009 Andrew, why not forget all that M20/M50 business, spending thousands trying to get pwr/trq. Just drop in a stock M30 engine & box from an E34, give you well over 200hp @ flywheel + 300-320nm torque. BMW did all the design work for you on this engine. Bulletproof boat anchor of an engine.....blow it up & Paulie Soprano can use it as a substitute for concrete gumboots on someone. Google Alpina's version...E30 B6s or go to: http://www.e30.de/335i/00.htm Have you joined the club yet? Give me a call so i can check out your car.

CamB 48 Report post Posted June 10, 2009 (edited) I have an S50 with 6 speed gearbox - $20k including the car . Seriously, chances of finding one with or without a gearbox for sub approx $8k (my guesstimate) in NZ are somewhat slim. What is the goal? How much power, and why...

Andre3000 55 Report post Posted June 10, 2009 Well im going to have to rebuild anyway because its burning a substntial amount of oil now, so i thought why not upgrade at the same time. In terms of tune-ability, are there gains to be had off a stock m52b28 double vanos? Quote Share this post Link to post Share on other sites
CamB 48 Report post Posted June 10, 2009 If you start replicating the setup of the US M50 based M3s (cams, decent headers, etc) I believe you can start getting quite decent power up top, but it would still struggle I think to get to 250hp. Having said that, anything over 200hp in an E30 is pretty quick... My vote is M52 or a fairly mild M20, otherwise the cost benefit ratio gets way out of whack.

Andre3000 55 Report post Posted June 10, 2009 Yeah im thinking of adding an itb intake (whether s50 or dbilas, im nt sure) and a decent exhaust system and leaving it at that. Who would do a conversion like this in auckland? I think iv sourced the engine. Quote Share this post Link to post Share on other sites

Who would do a conversion like this in auckland? I think iv sourced the engine. baverian motors do a bit of modding etc .there is a good read from a bmw uk mag about power upgrades for m52b28 . m30 is also quite tuneable and loads more torque Quote Share this post Link to post Share on other sites

Andre3000 55 Report post Posted June 10, 2009 (edited) m52 it is!!! Got me a nice engine thats done only a few kms. What a need now is; Manual transmission from a 96-98 e36 328i Drive Shaft from 96-98 e36 328i or e30 m3 Oil Sump from e34 525i (m50 oil sump) e36 engine mount arms e21 brake booster and a z3 or e36 powersteering rack If anyone has these parts id be glad to take them off your hands. Il give Ray a call tomorrow. Anything im missing? Edited June 10, 2009 by André3000 Quote Share this post Link to post Share on other sites

Il give Ray a call tomorrow. Anything im missing? Get a Getrag 250 G gearbox out of a 318I M44.... thats what I'm using.. cheaper and easier to find than a ZF With the sump you'll also need the oil pickup which is different You will also need a radiator.. I'd also use the E36 318 radiator with built in side tank. Many of the 328's in E36's use these. Youll also have to think about what flywheel your going to use and what clutch Youll also need a DME and wiring loom. The DME will have to be recoded or made up for non EWS & Manual You might also want to change the diff ratio further down the track.. I'm using a 3.15:1 or a 2.93:1 The only other things I see that are missing are.... a sh*t load of time and $$$$$$$ You probably wont have change left over from about $10,000 depending on whether you do it yourself or pay someone. BTW...M52B28 is only single vanos Edited June 10, 2009 by *Glenn* Quote Share this post Link to post Share on other sites

westy 614 Report post Posted June 10, 2009 Also, if your car has a Gretrag 260 you can use that and your current driveshaft. Your Gbox crossmember needs modding along with the shifter but probably easier then finding a ZF box and you can keep your diff. Quote Share this post Link to post Share on other sites

Had to mod the gearbox mount bracket and linkages because of the angle it all sits on Quote Share this post Link to post Share on other sites
Andre3000 55 Report post Posted June 10, 2009 Heres the engine: http://www.trademe.co.nz/Browse/Listing.aspx?id=222771318 And a few things im getting from VAC to make the job a little easier: Wiring Loom: https://store.nexternal.com/shared/StoreFro...rs&All=True Brake Booster: https://store.nexternal.com/shared/StoreFro...rs&All=True Oil Filter Lid: https://store.nexternal.com/shared/StoreFro...rs&All=True Clutch and Flywheel Package: https://store.nexternal.com/shared/StoreFro...motors&All= Pulleys: https://store.nexternal.com/shared/StoreFro...motors&All= Oil Pump Upgrade kit: https://store.nexternal.com/shared/StoreFro...motors&All= Iv read up a bit on the various transmissions and im going with the ZF. If you use the 96-98 328i drive shaft and use some part from the e30 drive shaft apparently that works, but il jump that hurdle when i come to it.

*Glenn* 855 Report post Posted June 10, 2009 (edited) That motor is out of an E46 not an E36.... more money to spend.. its also flyby wire throttle body you need a M52B28 motor not that one I would suggest you ring me Andrew Edited June 10, 2009 by *Glenn* Quote Share this post Link to post Share on other sites
westy 614 Report post Posted June 10, 2009 Best thing I can suggest is that you try and find either a written off, or cheap E36 328. It will give you nearly all the parts you need for a much cheaper price. Quote Share this post Link to post Share on other sites
