2.8L M52 Swap - Complete engine and then what else?

[dinanm3atl]

No. M3 was N/A. 328iC is N/A as well. I want to boost the M52 :) kekeke

You are having absolutely too much fun with this project. I can hardly wait to see the finished car.

[broach328]

check out godspeedproject.com theyve got some sweet stuff. nice turbos for 450. wastegates for 200. they have almost everything. you should turbo the m52.

[dinanm3atl]

I would probably supercharge. To be honest an e30 with 300whp is a handful and lots of fun. Breakaway on depend but damn quick in a straight line. I don't need the 'extra' power cap that a turbo would offer.

[broach328]

yeah. but supercharging is more pricey and greater load on the motor. regardless it would be pure sex either route you take. would you put together a kit or just order a full kit from AA?

[dinanm3atl]

Nah. S/C kits are going cheap 2nd hand nowadays. Best value in my opinion.

[matt]

supercharging is greater load on the motor?

Cheap supercharger kit + awesome tuning is probably the way to go for under $5k or so.

[broach328]

well it causes more stress on the motor because its constantly being spun by the belt as apposed to exhaust.

[lennon]

lol so that makes it more stressful on the motor? interesting viewpoint.

[dinanm3atl]

For sure Matt... and considering sub 2K for a used kit, many with bigger injectors and multiple belts/pulleys. Done deal!


S/C M52 would be super awesome in E30 me thinks.

[broach328]

yeah how would a turbo be stressful on the motor? exhaust spools it. superchargers are constantly weighing on the pulley. i wouldnt say its a great deal but over time i would say yes its stressful. ive always been told that by people who know much more than i.

[SpecM]

ive always been told that by people who know much more than i.

bingo

s/c don't put any more STRESS on an engine than turbos do. The stress comes from the extra air being rammed into the cylinders, and the treat/risk of detonation

s/c put more DRAG on an enigne, maybe that's what you mean

[broach328]

either way, if i ever boost my m52 it will be a s/c. i like the idea better and i dont want huge power. i think 275-290whp is PLENTY for these cars. 300+ wont get to the ground.

i can atleast do your harness modification if you would like.

crank sensor
cam sensor
knock sensors
engine temp sensor
cluster sensor (drill and tap head/drillout TB coolant hose hole and re tap/rethread sensor)
maf from obd1 vanos motor.
obd1 O2 sensor
413 ecy
obd1 throttle body
obd1 vanos intake manifold
welded obd2 manifolds

what trans are you going with? i would suggest the zf for the plug and play factor.

i am sure this would all still apply for an s52?
would you still be able to use obd1 coils?

[Unearth078]

no help?
