Ok Me and a friend are doing a Mini me swap soon and I have a few questions. It's a Y8 head with a 90 D15 block. We looked up what the piston to pin clearance is on the D-series and B and there the same. So that tells us that the B16 pistons can be put on his rods.... right?? We found out that we would have to bore to 81mm and the stock d-series bore is 74mm correct? we will be putting new bearings and possibly shot peening the rods.(how much does this run?) also should we plane the deck and resurface the head? We will also be keeping it OBDO and putting his old DX harness on there with an SI Dist. and we will have to convert to MPFI. The PR3 or PWO should be suitible right? Most importantly is if these pistons work will the piston to vaalve clearance be OK? Please add info and comments. We want it to be pretty quick so any cheap tricks or ideas will be appreciated. Lastly, what kind of compression ratio will I be looking at? I'm sure I'm forgeting things so help me out. Thanks.

 

B-series rods can be used with some machining. However, B-series pistons will not work. Boring out the D-series sleeves to 81mm will leave them really thin. It would be a better idea to get aftermarket D-series pistons. For additional info there is a article that was posted here not too long ago.

Thanks alot.... What about an oil line for the Oil pressure switch. I will have to do that right? and if so... where is a good place to get one.

 

You don't need an oil line for a mini me. Just remember to remove the oil control jet in the D15 block before you put the head on.

 

can I get a pic or discription of where that is? Also what power do these minime's usually make..... about the same as a D16y8?(or EX) and what compression due these motors usually put out? Thanks again.

 

Did you look at the link in my previous post? It's got all the info you need.

 

^^^thats a very good write up. also do a search on TurboPanda he was using a hybrid rod/piston set up. B16rod with Supra piston.
I on the other hand was lucky and found some D16A1 rods that was already shotpeened running that with srp. ur looking around 10.2:1 comps. good luck
