boosted_b16

a b16 or ls swap will be just as powerfull as this built up mini me with a cam and itb's, what a waste of money and effort man if you want decent all motor power with stock parts get an ls block, a set of b16 pistons, a b16 head, and a set of gsr cams, this set up will cost less money than your itb and cammed sohc and i gaurantee will break 180 whp if tuned....

Thanks but I don't really care. I guarantee you I'm going to be spending less on this than I am on either of the above suggestions. I can get a short block for $100, Like I said I just picked up a head for $50, tranny is $75, etc. Those ITBs I mentioned I'm getting for free. I can have all the necessary ingredients for this for less than $500, the full rebuild and swap will probably total less than $1000.

LS or B16A will have a higher buy-in and being detail-oriented like I am I wouldn't feel right swapping it in without rebuilding it first just to make sure it's going to run for a while.

As I've said, straight-line power is not a priority here, I'm just building something for fun in my spare time.

You can try this...same combo as mentioned (a6 block/pg7 or pm7 pistons/z6 head) and run a standard headgasket for the a6. Downfall is it's a composite gasket, but it'll be fine for n/a and is thicker than the z6 one. That will drop you down to the 11.67:1 range, which will work fine.
For the intake and exhaust manifolds, you can use a z6 or y8 intake manifold, but not the old a6 unit...different bolt pattern. For the exhaust you can use any for a d-series (except the newer bastard d17's), but I would HIGHLY reccomend getting some type of aftermarket header. If you could find one with stepped primaries, that would be great, but even a run of the mill ebay header will be ok.
Sure will, but at a price tag of well over $1000, especially when factoring in mounts, linkages, axles, tranny, ecu, etc. Add in the cost of buying those parts to build that b18, and even with awesome cheap deals you're still going to be over $1500. Hell, for under $1000 (maybe even under $500 ) I could build a turbo kit for a d16a6 that would still put down more than 180hp :P
Face it...D-series is king of cheap for all-motor.
