Ben

Going to make some high rise RSM's like these at work next week Does anyone have the PCD of mount holes and general dimensions of OEM RSM's? (cant get to mine atm)

Subaru is a different kettle of fish tbh Mine has a similar size turbo to dsr380 and i have full boost by 3500 and it holds solid till redline and i could probably bring that down lower with a little more tuning Put simply with a smaller turbo your going to need more boost to reach your hp goals so if you want to retain that turbo and shoot for big hp either lower your compression or use a bigger turbo Thicker hg with arp studs works fine going off the usa forums Lower CR pistons would be best Im using standard CR with buckets of overlap and a big mumma turbo for my current build

Nope dont bother with a piggy back dme uses internal ignitors making it difficult to tune ignition timing Either get the dme remapped or use a standalone Ive looked into every alternative including fmu, safc2 etc. and these are the only two that are worth doing imho Just use your megasquirt its been proven to work and it will save you alot of time and effort

Fair enough I used a similar sized turbo on my last setup and had next to no lag Your not worried about boost tapering off at higher revs? I would have thought the dsr430 would have been a better match nissan guys use them and still have a low boost thresh hold Have you lowered compression or standard C/R?

What are you using for tuning?

Yup common practice but you will need to take some meat off the back of the flywheel and use an e21 release bearing. EDIT - beaten to it lol

Awww how cute Jokes aside Why are you using such a small turbo?

Whats the specs on ya turbo?

Ive got one for sale if you need one andy

1100lb sheez stuff that for a road car My subaru is softer than that and the rides so harsh ive contemplated getting a sports bra to hold my slightly overweight man titties in place anyway why dont you just get 1100lb springs that are 40mm shorter than the first ones?

Easy out end of story

Haha I love the extravagance

Lol at your foolishness Its clowns like you that drive away valuable forum members Quality posts made by "rjac001" = 0 Quality posts made by "crunchy" = all

I dunno if i would say making it yourself isnt doing it properly but to each their own It wasnt so obvious at first thought it was just worn bushes then as it got worse It sounded like a wheel bearing. Found out it was the diff mounts when i pulled over in cambridge then drove home to welly with 1 bolt holding my diff in

Mines a 1990 I had the same problem with the diff mounts. mine ripped out 3 of them though. I dont know what the reinforcement plates look like but to fix mine used 6 mm plate folded around the contour of the mount area then welded the crap out of it

Dunno if thats aimed at my post or not but i just assumed he had a new ecu with zero settings on it and as a newbie tuner myself ive found working off a "base tune" is easier than starting from scratch. It might be different for you cause you know what your doing but for a ham fist sausage finger like me I like to know that at one stage that tune worked for someone else so if i mash enough buttons it will eventually work for me

whats tragic is ^that^ post had better spelling than the trademe auction

Go on the mapecu forum and search for m30 turbo map Pretty sure they had a base map or someone had shared one or something along those lines Then just modify maps to suit your setup EDIT- go on mapecu.com > support > base tables > BMW Lists "BMW Turbocharged 535i" as a downloadable table tweak it for your chit and Job done.

This guys trying to sell this as an oem turbo m50b25nv engine Visit My Website lol

What size holset are you using?

m50b20 has a smaller diameter intake to m50b25NV fyi

Has it slipped on you yet? What clutch disc did you use?

I just got off the phone to mp auto in upper hutt they told me the max clamp they have seen from a modified stock M20 pressure plate is 1900lb. Has anyone got more than this? Also is there some sort of guide for clamp vs hp/torque?
