Nope.

Then why is it bad ?

lower comp = more boost + fuel means more power... well the old ways LOL.... But with a lower comp, ur lower end torque/power might suffer from my understanding...

Alot of the newer cars have high comp low boost which is really good for a daily, good low end torque...

Its all about torque!!! Thats what puts you back in your seat... flat torque curves will provide good pulling power throughout the rev range

1.6L engines will not provide this on their own and will only come close with forced induction

There are a couple of vtec D - series motors on ebay at the moment just waiting for boost

Unless you're planning to make huge amounts of boost, the vitara pistons lower the engines compression too much. The engine would be an unresponsive pig and low/medium rpm.

hi guys ive built a d16a8/zx twincam turbo motor.and im very happy with it as the punishment ive given it..and put 28 pounds of boost through it.and still holds there cheap and they make good power.i use the vitara piston rod kit from a supplier in the us,the bottom ends a very robust as they have a cradle for the mains and the stock cylinders have not split,i used a block brace an welded it in the machined the deck.the studs i found are from a vw gulf the use 11.5 mm studs not like the sohc that use 10mm,so i could clamp the head right down to about 90 pounds of talk helps to run big boost.made my own intake and exhaust manifolds.and runninga t3/t4 turbo that cost me 200bucks,38mm gate,ebay,microtec ecu the cars been on the road for about 7months now with no probs.but not with 28pis 18-20 for every day use thats my bit.just sorting out the box going to open it up and try an obx lsd if any one has there opinion on these items,cheers

^ Sounds awesome. What kind of power does it make on 18-20 PSI and 28 PSI? Somebody I know was making about 245kw on around 28-30

[beeza]

Awesome mate,SICK!!

[~Sp33~]

the studs i found are from a vw gulf the use 11.5 mm studs not like the sohc that use 10mm,so i could clamp the head right down to about 90 pounds of talk helps to run big boost.

Were all the head studs equal length?

Go with Mfactory LSD, its only 650 or so, better to pay bit extra, an many ppl go by it, obx not so much, might be cheaper but it breaks easier

Bottom line is before,top is after.I lost no high end and pick up all the to red line,so stoked!

It was 1 deg. retarded,now it's 7 deg. advanced and $220

Sick, what race track is that beeza, don't think i've been to that one before.
