CA18ET/DET hybrid build.

[Westerlund]

First of all, english is not my first language so im sorry for my bad grammar/spelling.

A couple of months ago i bought a 88 s12 hatch with the CA18ET engine in.
I have decided to build a new engine for it and have starting to prep a DET block that i was going to put the ET head on to keep the old school look and the MOT guys happy.

The setup i was planing to run is:

Bottom:

*CA18det block
*Stock DET pistons and rods
*New oem DET oil pump
*Stock DET fly wheel machined for a Sachs 618 plate.
*New bearings

Head:

*CA18ET head
*Cometic MLS head gasket
*ARP head studs
*Maybe re-grind the stock cam
*Stock manifold (will port it)
*Stock intake

Air/and fuel:

*z32 MAF
*444cc GTR injectors with modified rail.
*Stock s14 turbo gt2860
*300x600 greddy IC
*AEM A/IC piggyback
*Blitz boost controler
*2.5" or 3" custom exhaust


The problems/questions so far i have read or noticed are:

The ET head head studs are 10mm and the DET are 11mm so i will need to drill the holes in the head a bit.

The DET crank is a larger diameter were the timing belt gear sits, have any one machined the ET timing gear to fit it on the DET crank or how did you solve that issue?

Does anyone have any experience of the AEM piggy back? I want to use that beacuse the ability to adjust the ignition to, not just the fuel.
The car will run on E85 so adjusting the ignition is a must to be able to get full advantage of the better fuel.
I've read that some people had problems with the AEM om newer cars like the Lexus GS300 that the stock computer did now want to cope with the AEM, so i was thinking if anyone var had this kind of problems with the s12?


My goal is to get around 300whp with this set up and use as much Nissan OEM parts as possible to make it a sleeper and road legal.

I was hopeing to get some good answers or input abot this set up and how you solve the timing gear issue.

Thanks
