Wow...With the Local BMWCCA, I would get bumped

Don't some organizations have hp/weight ratio-based classes?

Different clubs have different classing rules. My club and SCCA are very similar points based rules, can't speak for BMWCCA though.

Grrr

Tony, I wish I'd seen your post earlier this week.
You make a great case for keeping the stock i, and since I already have a base DIYPNP tune from the last build of this engine, it would have been easier.

Not having seen the post however, on Wednesday I went ahead with the frankensteining the m20.

The 2.5i engine that came with the car was in pieces. Looking at the rods, I was really worried that they were all mismatched (only three seemed to have matching pairs of upper and lower lobes and the remaining three seemed to be different).

As a result I've put the eta crank and rods in the i block using the i pistons. (I realized that the head bolts were probably left in Alabama where I picked up the car, so I didn't get a chance to put the head on)

If this combination will yield such a low compression (7.xx:1) I wonder if I should pull out the pistons and go back to the original setup...

I'll monitor this tread more closely from now on...

That combo will put the pistons to low in the cylinder at TDC, won't work. You would need to deck the block like 2.5-3mm IIRC which is not advisable. Its been a while since I ran all these numbers so validate anything I say, but to do what you want, you either need sETA or 528e pistons from '88 model years respectively which would let you run 135mm (i) rods on the 81mm 'e' crank, and the 885 'i' head. That would put you back at the stock 'i' 8.8:1 CR and allow stock head gasket thickness.

Thanks Tony.
I'm getting off the stroker wagon for the moment. I've just spent the evening removing the frankensteined bottom end and putting together the standard 2.5i configuration.
I have concerns as some one of the rod caps looked pretty beat up, on of the rods wasn't spinning very freely on its connecting pin (to the piston) and the crank had some damage (which may have occurred during the transportation).
In any case, I'm starting from the beginning in hope of learning from what i have.
This is my first time putting the whole engine together and I have a growing suspicion that this engine will not last very long.
In the meantime I may look for a M52 crank and prep a 2.8 for next year or for when the faithful moment a bearing blows out or something else fails.
It looks like there are some events happening at Blackhawk farms in August.
If I can get this thing put together, I wll try to make it.
Even if I can't get it ready, I will come out to check out the crowd.

My suggestion is buy a used b25 for a few hundred bucks, throw it in and go racing. That will give you a running car and plenty of time to build a solid stroker with the right parts, or just a fresh 2.5. We have a drivers school coming up on Aug, lots of track time and classroom instruction. You get an instructor in car all day. I should be instructing that day so I would likely be assigned to you since your in an e30.

That was my idea with getting the 2.7 lower end... It'll have to wait I've burned through my budget for the year...

As far as the driving school at blackhawk farms I am all for it.
Do I need to be a member? I'm guessing I need to bring my own vehicle.
A lot of things have to go smoothly with the car build for it to be ready by the 3rd.
I only have one seat right now too so it'll be hard to have an instructor riding with me...

yeah you need to be a member for the school, but you don't need to be a member to run at our regular events.

Tony,
I went to the NSSCC school at the autobahn last weekend and put in for my membership to the Midwest Council.
All I have left is to sort out the tuning and address a newly discovered oil leak and I should be good to go.
I look forward to stretching the cars legs this season.

Awesome! Our first points event is at Blackhawk on May 3rd. I have a problem I need to fix too, I wish this damn weather would clear up so I could test drive the car...Have you classed your car yet? That's very important if you want to be competitive, and I was way off my first time around. Post up some pics of the car and all your mods and I'll help you out.

Yep looking forward to it.
I'm afraid I may not be ready for it yet. Worse comes to worst, I have a set of 17" wheels to put on my dd e46 so I can just come and get my beak wet...

I haven't tried to get the car classed yet though looking at the points schedule and I think i'm somewhere in the 20's so at least modified class.

I haven't taken many photos of the car because I haven't taken it out of the garage much.

This is what it looked like when the po raced it:

Are you going to run those R-comps?

How wide are the wheels? What dia?

What suspension upgrades?

Bigger sway bars?

Upgraded brakes (bbk)?

Engine work?

Just from the pics you'll be taking points for aero and weight reduction. I think your going to end up in a race class TBH, depends on your answers to the above questions. I'll go through the GCR later this weekend and see what else I can dig up. I need to anyway to get my car prepped.

Suspension includes Bilstein Sport strut inserts in the front with Ground Control camber plates and coilover conversion. The rear end utilizes Bilstein Sport shocks with JBRacing Solid upper shock mounts and height adjusters. Swaybars are UUC Swaybarbarian 22mm front and 19mm rear adjustable. Eibach race springs.
4 XXR 527 wheels 17x9.75 flat black
2 XXR 527 wheels 17x8.25 flat black
4 Hoosier Koni race slicks 275/40/17
2 Hoosier Koni race slicks 225/45/17

Engine is stockish. VACmotorsports race valve springs (dual spring design, good for 11,000 rpm bursts) factory size valves, CatCams 287 cam and adjustable cam sprocket and 19lbs injectors running on megasqirt.
Looks good on paper though not yet track ready.

Oh the brakes are stock with hawk hp+ pads and the Mini Cooper wheels are 205/65/16 on Bridgestone street tires that probably aren't ideal for track purposes.

Here is our points breakdown:

Just at a glance your pushing 23+ points so your going to be in a Race or Street Tire class.
