Am I doing this right?

New HP: 210
Points Added to VPi: 73
--->NEW VPI: 523
 

 

Looks like you forgot to apply the winter package factor which subtracts as many points as you need, in this particular case the quantity would be 23.

Or I could run a automatic and get -75 without any secret packages or handshakes.

 

Next question (to anyone )

What should be done with the 7 points I have left  in my imaginary build?

But

I may need 5 of those pts if the rad wont work with the swap, no clue till I try... may be 6 mo from now.

ASSuming I can make it fit, can the stock rad deal with 100hp more?

7 points of ducting for the trans cooler.

So, what you should do is get a 325i and do the same swap instead of starting with 325e. Then you get the 64 liter fuel tank instead of 55 liters, the stock diff is better too (3.73 lsd).

 

7 points to max out at 530? 3.5 sq. ft. aluminium shark fin.

The stock rad can handle S54 swaps (330hp) so you should be good to go.

 

Your 7 points will likely go to SQft materials costs to cover the wheels and protect the engine bits

Does the 3:73 diff need any cooling for continuous duty @ that power level?

 

Just figured out where a few pts are going, fender flairs....

 

No.  Its good to go.

530 huh, how about 523 + 25 (trans swap) - 75 (Auto trans) + 20 (trans cooler)= 493

 

Noted, will look for a 325i

Gotcha. I must have missed the change that allowed you to swap to a non-OE automatic and keep the -75. It used to be -75 for OE automatic only. That could be seriously reliable if you stick in whatever tank of an automatic that handles your current infinity v8!

 

Also, you don’t really need a 325i, just claim one. I think once you replace tank with fuel cell, replace engine, trans, diff, there will be no way to tell the 325e from a 325i. Maybe.

The calc is now accurate with what was in the rulebook about using highest trim version.

 

Nope :( 

He chose the highest trim himself, e30(M20B25), which was the correct (but inconsistently applied) way to do it in 2018. 

Since that rule was dropped for 2019 I'm assuming the swap calculator will be updated (soon), but it hasn't been yet.

 

The calculator shows his 325e (E30-M20B27) is still starting at 375pts for now.

Oh, thanks for pointing that out. I too assumed that it had been changed.

We run a stock radiator with our M54B30 swap. Been in there 3 years, never had any issues. We run an electric fan in front of radiator but only use it when stopped for more than a few minutes.

Back to the top

 

Sharky is a blast to drive and could be faster with a bit of dedicated development and $$ but we are getting consumed by consumables, the infiniti/bmw bastard combo has come back top of team talk.

 

With a repurposed  a/c condenser as trans cooler, this concept produces a 473 pt car, assuming we run wide tires and need some material pts for wheel flairs, also assuming I know nothing about this chassis and belong to no bmw forums, what other free and points sucking items will be required to make a e30 work?

 

What e30 specific chassis maintenance is required on a 110,000 mile car to go racing?

 

Bushings=0

Struts=0

Brakes=0

Flairs= material per sq/ft
