The exhaust will restrict you but it will work for the time being. The standard centre and especially rear silencer are the biggest restrictions. Changine them will help a great deal alone. Go to 2 1/2" straight through with that setup Or anything upto 3" if you want to allow for future mods. Make one out of universal pipe and an overaxle bend from demontweeks for cheap enough
 Other worthwhile mods are an electric fan. Grab one from the scrappy if on a budget. A piggyback ecu for the s13 injectors will be needed. Other than that you've pretty much got it planned out very well. Glad to see your not neglecting the fuel pump  the piper cam doesnt really give you much power for money spent so i wouldnt really be too concerned/botherd about doing that unless your planning on using a t28rs or t3 etc

Whilst your bottom end is in bits, take your rods/pistons crank and flywheel to ' Burton power ' and have them lightened/balanced. I priced it up ages ago and it was only about 140. They can also hone your block or bore it to suit!

also might be worth seeing if the crankcase girdle from the DET will fit straight on to stiffen the block. take teh longer bearing cap bolts too

cheers for the info chaps! i've already got a silvia engineering twin kenlow set up but forgot to mention it! haven't really got money for lightened and balanced bottom end coz gettin engine gaskets, rings and shells is gonna use most of wot i've got! i was under the impression that the s13 injectors would just run off the standard ecu! wot sort of piggy back system is needed or could i get away with an uprated pressure reg for a while until sorted?

Its an electronic gismo that you wire in to certain point before the ECU which allows you to change things like fueling etc.
