346hp,329ft/lbs@15psi w/ the clutch slipping after torque peak. 170k mile untouched motor, head has never been off. Cars getting taken apart for vems and a clutch. Dyno charts and stuff later. No time at the moment, got stuff to make. Im content for the moment.

jon volks car-impressive high mile m20!!!!!!what a guy

[maxfield]

impressive figures especially on a 170k motor untouched

[gcorky]

its just testiment to the ole m20

hes fabbing cool short runner intakes but bit pricey for me...

[jon_volk]

Thanks guys! Im happy so far, theres still plenty more to come. Its a well used lump but its still got more left in it

[gcorky]

what turbo is yours john?

[jon_volk]

Its an hx40

http://www.666fabrication.com/e30.html for most of the specs.

Its getting some changes from that list right now so Ive gotta update it in a few days.

on your M50 manifold picture it looks like wastegate will interfere with compressor hosuing maybe it just that I cant see angle its pointing at

[gcorky]

whats the idea behind the m50 tb.....curious?

It doesnt interfere with the compressor since its a bottom mount manifold w/ the wg facing the exhaust side. The wastegate is not bolted directly to the manifold. Its remotely mounted down by the tranny. A tube just bolts to that flange b/c I cant account for every turbo/downpipe configuration. I sell most of these manifolds through other shops who install on site so its never really an issue. Since there isnt any off the shelf DIY piping kits for e36's really some custom fab is in order no matter what.

The m50 tb is b/c it has a variable tps sensor for the engine management and its slightly larger than the M20 unit. Its also what I will be using for the short runner intake so I wanted to keep things consistent since TB changes would skew dyno results from switching to a short runner intake. The elbow is welded on b/c it needs to be away from the manifold for all the throttle linkage to clear the runners.

What's the low end torque like with the stubby intake manifolds?
