Pictures of the modified oil pan for this kit conversion.
Here are the pics of the modified pan. Note the area clearanced for the subframe, and new, relocated oil drain plug.
Sorry, I forgot to ask a few questions in my PM so I figured I'd ask them here.
1- Will this conversion kit work with a 20B running stock twin turbos?
2- Is the ONLY modification required to make in the intake clear, cutting the LIM? If so, do you have exact numbers or would it be better to test fit the engine and then decide?
3- I noticed you mentioned that in order to make this work you will have to use the FD power steering bracket, and a few other FD components. The question I have is will this kit still work if I plan on removing the powersteering altogether?
Thanks again,
Rizwan

Not trying to put words in anyone's mouth, just trying to help out. I've talked a good deal with GTORX7 and have gone through pretty much all the same crap you are right now.
I ended up with this kit, and I am glad I did.
1) Yes, he has a kit that will allow you to run stock turbos, just specify it before he starts building. The only real difference, I believe, is simply allowing for the rear oil return line for the turbos to reach the block easily.
2) Sort of. . .in lowering the UIM via cutting the LIM, you necessarily lower the intake elbow as well, right where your PS pump goes. However, if you're not using PS, which you don't have to with this kit, this won't be an issue. You will probably have to relocate the alternator, but i'm not sure. Lastly, you will have to modify the oil fill neck, which is MUCH easier than the LIM, so it should in no way be a camel-back-breaking straw.
3) No, although I'd keep the PS, but that's just my opinion, there are many others who disagree. I guess it depends on what you're trying to do with the car.
If you have any questions concerning this kit, I'd be glad to answer them, if you can't tell already, i'm quite happy with it. My setup is C171 block with GT42R, PS in tact with FD everything per this kits instructions.
hope that helps

Thanks Ryan! That was actually very helpful. I'll be PM'ing you shortly regarding a few more questions. I PM'd GTORX7, but I'm guessing he's a little busy. I'm in no hurry though so I'll continue gathering information until then.

These parts are not pictured, but included in the cost of the kit-
-20B oil pan, sent in/ modified
-FD steering rack, sent in/ modified
- P/S and A/C bracket, sent in/modified (pictured)
- Alternator tensioner bracket, sent in/ modified (pictured)
Parts that are made in house, and pictured-
-Two custom steel plate motor mounts
-Two poly bushing mounts
- (6) Machined spacers for the motor mounts
-Machined water pump outlet
- Machined Idler tensioner, spacer
- Ball bearing Idler pulley
- Full hardware, grade 8 bolts, stainless lock nuts
Cost varies with options selected by purchaser, as follows-
Full conversion, MIG welded steel motor mounts- $1,570.00
Full conversion, TIG welded steel motor mounts- $1,670.00
Optional color anodizing of aluminum parts- + $150.00
This conversion kit is different from a subframe kit, as it retains your full factory subframe. It will keep the steering rack in its perfect, original place. The transmission remains unmoved. And lastly, the 20B can be installed without a Fd rear plate, or other tricks. Two downsides to this kit- Stock intake will have to be modified lower! You will loose the A/C compressor, this maybe will change in the future, as more development is done.

Using a FD S6 front cover, no factory 20b CAS!! Just drilled some holes for the front cover in the oil pan, took 5-minutes. Had to cut off the top pressure feed on the steering rack, relocated it to the side, allowed much lower mounting. relocated the alternator to where the a/c was. that was it, no bump steer, ( Very important in a drift/ road race car) all factory placement. Am I the first?? who knows.

ALSO- On my prototype kit, I "notched" the back of the subframe. But now, I simply modify the oil pan to clear the stock subframe. This makes for one very very clean install!!

That all depends, if you have a power steering rack that has been converted, hopfully it still has the pressure fittings. The reason being is you can then have a reservoir holding the p.s fluid and looped from inlet to outlet. If they did it like this, then yes you will have to modify it still. If they just capped off everything, and welded shut the fittings, then the seals might blow out on the rack, or cause extra hard steering.
As can be seen from this thread.

Im glad you decedid to come out with this and hope it goes well.....You think withh all these people talking about doing and are doing these projects with a 20b, that the rx7 shops, one of them or all of them would develop a drop in kit and motor or something, everyone is so worried about making fast money instead of grad. or a residual income not a one time wam bam thank you mam I rapped you thing.........
just my 2 cents but I think your setup is going to do good
