I'm torn between 2 engines *poll*

Why do people always say that m30s suck? They only weigh like 15lbs more than a 24v and they can make over 230hp with just a chip. They aren't hard to put in and the wiring is almost plug and play.

I voted m30 turbo.

Because they are not all that frugal on fuel is my reasoning. Plus they are not as common as they once were.

They don't "suck", but they're getting older. They're heavier and larger, so that weight sits further forward. Save for the timing belt, they're nearly as maintenence intensive as the M20, whereas the M50 is almost a "change the oil & plugs" motor.

I'd say put the ITB's on last when you've got the rest of the mods in place because it's not worth it unless you've got a big spec M30(see below).

big cam circa 290-300 duration
head work done to suit your power target/compliment your other mods
Vernier cam sprocket
pistons to give you roughly 11.0:1 C/R
6 branch manifold
TPS angle based stand alone ECU

I was in the process of making an adapter plate for some E28 M5 ITB's(45mm) but i thought they were too big and to much work.

I've got a mod for the M30 thats admittedly not as cool as ITB's but a bit less work/money, it gets you a decent increase in TB size with out being excessive. It sounds nice with the CDA air filter pod.

This is a twin 60mm TB from a Ford V8 Mustang(?), wheather it's a worth while mod or not i'll have to wait till the 22nd when it's going to be mapped.

Just an idea for you to mull over whilst your in the planning stage of your project.

2.8L M30 maybe.

Those 2 are already done, would you mind explaining the Pro's to having a vernier cam sprocket?

did you modify the firewall at all to mount the engine further back?

seems like you have some more room than most people do in between the distributor and radiator. or maybe its just the angle.

:)

another option i was possibly thinking about was to supercharge it with an m-60 or m-90 charger, or maybe even a belt driven turbo type charger. then blowing through the ITB's and using a small inter-cooler that i have from a isuzu impulse that i used when i helped my friend put an m-30? (the charger from an clk kompressor..the little 2 seater with a 2.5lt) on his 2.1LT golf with ITB's. it worked out nicely. i talked to Dbilas and they told me the throttle shafts have o-rings so they would hold boost with out issues.
you could always add that down the line, for an even cooler sound, and even more torque out of thte m-30

haha your making me sign away more and more of my paychecks man. sounds really cool though. when are you planning on starting your swap?

i'm going to pick up my engine tomorrow. i got a euro l-block with a 292 cam, port and polish, billet race rockers, and oversized intake and exhaust valves. bottom end is stock, but im going to get a u.s. crank and rods with forged pistons in there before the engine touches the car.

with just the U.s. internals i should have somewhere around 3.8 to 3.9 m30. :) and around 240-250 whp with proper tuning. then i'll start fabricating my itb setup. im going with gsx-r 750 throttle bodies.

[der affe]

prob going to start the swap the beginning of summer, maybe spring, i need to get some more stuff lined up to finish the swap, and since i was burned i have to be careful what i do as not to upset the insurance, and i know i am going to have to go for hand surgery and possible dermabrasion (where they sand off the keloiding scars) in my future also. i go see the hand surgeon on Tuesday for a consultation. i also need to pick up another car to drive while doing the swap. i AM NOT going to daily the 914-6 again while i work on a project car. i want to keep the milage down and that car, while fun, is no fun to drive all the time.

why are you putting the us internals in the euro motor. are they stronger? longer stroke crank and longer rods?

what is the manufacture of the 292 cam? i was looking for something around 290 with out going to the 300+ cam. Dbilas was the only company i could find with similar specs.

BTW the chargers are cheap on ebay (m-60 m-90) and can be found at pic-a-parts pretty easily. they are from supercharged t-birds.

2.8L M30 maybe.

Or 3.0L carbed.

S38!

Wonder if this is a 3.8?

A vernier cam sprocket helps you to get the valve timing back in spec if say the head/block has been skimmed(which retards the cam timming) too much but mostly it's allows you to tweak the valve timing which effects the where power delivery is in the rev range to a certain extent.

It is only a tweak or an optimization to suit the rest of the set up and what you are trying to achieve, i've been told that you might be able to squeeze another 5-10bhp out of a cammed M20 by advancing the cam 3 degrees.

My basic understanding of them is below, but this is a generalization as some engines might react differently.

Advanced cam timing = peak torque/power is achieved higher in the rev range, higher peak power might lead to more BHP
Retarded cam timing = peak torque/power is achieved lower in the rev range which might lead to more torque but might negatively affect peak power ?

The way to set them up properly is on an RR so you can measure the changes in the power as you try differing cam timing and optimize it to suit what you want.

Before you do this you need to know the safe range of adjustment you can use before you get a nice set of bent valves :-)

You need to dummy fit and torque the head down with a used H/G and measure the piston to valve clearance to figure out the safe range of adjustment of the venier sprocket.

My engine uses E30.de mounts on P3, i needed to hammer the bulkhead a little but you can't see it normally. I'm not using a rotor arm and dizzy cap, instead i'm using a Ford V6 coil pack which is ran by my stand alone ECU.

[blueapplesoda]

i didnt read the whole thread but turbo all the way

2k for 30hp
or
2k for ~100hp

buy an intercooler if u go turbo though. I still have my a/c, and if you are diligent and smart about things you can too.
