327i swap kit:
Head:
ported 325i cylinder head with dual valve springs
intake ports enlarged, smoothed, reshaped
exhaust ports enlarged and smoothed
head milled 0.040" for higher compression
comes with valve cover
Intake manifold:
325i intake ported to match head
325i throttle body
all ICV, PCV, vacuum and booster hoses, and check valves
Fuel rail with FPR
Exhaust manifolds:
325i exhaust manifolds sprayed with aluminum high temp ceramic paint, but need to be resprayed
port matched to cylinder head
New valve cover gasket and cam plugs
Rebuilt 60k miles ago with new cam seal and valve guide seals
Electronics:
87 325i wiring harness- verified direct plug in for 86/87 325e - tach and current fuel consumption on OBC will work with no splicing (this is not true of 88 and later harnesses)
All sensors including the timing sensor at the balancer
plug wires including the #6 wire with sensor needed for Motronic 1.3
All injectors (M50 injectors available +$75)
O2 sensor
ICV
TPS
AFM
ECU
Instrument cluster with 7k tach. Everything works on it except the odometer, but we can talk about having that repaired if you need.
Misc:
All brackets
88 325e (super eta) balancer- this balancer is designed for the longer stroke crank. A 325i balancer can be used- it will drive the water pump slower, but it is not sized for the throw on the crank. I can provide either. It is up to you which you want to use. Discount if you don't need either (but you can't use a Motronic 1.1 balancer.)
thermostat housing with hose to block off port for throttle body heater
plug for engine block to block off other throttle body heater port (never had a problem doing this even in 20 degree weather)
Any drive belts that I have that are still good.
timing belt and tensioner used for 5 minutes (see notes)
Options:
325i catalytic converter with 2 in 2 out
325i cat back exhaust
Late 325i cooling system upgrade- the 327i kit will work with your early radiator just fine. I used my old style radiator with AC on my car for 60k miles with no problem. If, however, you want to increase your cooling system horsepower capacity, I can sell you all of the late model 325i components. This will include the coolant tank with sensor and bracket, late radiator brackets and rubber pieces, all hoses, coolant crossover pipe, fan shroud with clips, and water pump. You may need to redo the wiring for the coolant level sensor, since it will be on the wrong side of the car. You will then be able to run an E36 radiator if you wish.
Notes:
I am NOT currently interested in parting this kit out. I want to sell it to someone that really wants a 327i
I ran this on my 86 and flogged it every day with no problems. The crank took it just fine
These components will work on an 86/87 325e with no problems. Any that do not have a round harness connector will require wiring.
For super eta/ or 325i owners- this head will fit BUT there may be valve clearance issues because of the milled head. It will be up to you to make provisions for this. There is no such problem with any 84-86 325e, but you should still make certain that everything clears properly! I found out that the valve clearance is too close for comfort on a 325i. That is why you will get a brand new timing belt and tensioner pulley and why the pics show the head installed on the 90 325i. I never got a chance to drive the car this way- I had to back off the valve adjustment too far for the valves to clear the pistons. I did not want to run it this way and am ready to pull it all apart again. I will guarantee that there are no bent valves when it leaves the shop.
This kit should be used with an i flywheel (which I cannot provide) and at least a 3.45 diff. I recommend a 3.73. I ran a single mass e flywheel and a 3.25 which was pretty good for towing and fuel economy (31mpg at 75mph), but there is a bit of a lag off idle due to the aggressive porting. This is normal even with a 325i running a 3.25 diff. The top end is fantastic, though.
I recommend finding someone that can provide chip tuning to take advantage of the porting and increased displacement over the stock M20B25 engine the software was originally designed for.
I will not be responsible if you bend valves due to improper installation, handling, etc.
I will photograph, crate, insure, and ship the parts. After that, any damage is not my problem.
I will provide technical support over the internet and will provide daytime contact information and the physical address of the shop I work from- you can rest assured that I will not stiff you.
I spent a lot of time and scronged for a while to put this kit together. I am getting out of E30s for a while, so I want to pass it all on to someone that needs it.
