16V Questions

[Jihaad]

Hi im busy building a 16v motor ,things i have done so far are ,KR block ,conrods polished ,Nissan CA18 pistons and 2L crank.Now i wanted to know will the pistons not hit the head? Pistons has been worked to clear valves ,but im worried about the dome on the piston hitting the face of the head. also what size cams do i go for was thinking 300? head will be made solid lifter with Toyota ITB's. What Radiator set up? to give a nice clean flow of air. Also i welcome any advice.

contact sarel elof from 8v performance or sent a pm to panic

[Jihaad]

Thanks Wit ARK but I don't like to send PM's as another person might be looking forward to the replies.

Someone ,anyone?

When you build an engine like that then you have to do what is called dummy assembly where you check if that kind of thing does not happen.

300 degree cams on a 16v? revs to infinity & beyond

[Jihaad]

i want something that's quick of the line and cant still maintain to run a 800m stretch.

[panic-mechanic]

All in first gear? or do you mind to shift a couple of times in between?
longest cams for a 16v that you don't want to rev to 10000 rpm is 276's and on an 1800 that will already be too long. Rather go like 276 exhaust and 268 intake. They are nothing like 8v's when it comes to cam choice.

Lol i suppose i would be OK with shifting once or twice.A guy in Cape Town is running 298's and he does a quarter mile in 12.4sec. Do i not need high lift cams for the ITB's? But like you said i don't want to make power at 10 000RPM

[Brat Boy]

he prob just said he runs 298's. it doesnt mean he is really running it!!!

civic radiator ,276 vd cams+headwork, the 43mm silvertop throttles with a rowland intake works best ...we have a similar setup in my bros car

[Jihaad]

I spoke to Nellis today and he advised that i use a 288 cam for my application. I want mid range to top end power. Will a 84.5mm bore not compensate for the low down torque?. Shuaib i think 43mm throttles is a tiny bit to small as well as the 276 cam. i understand that throttles need lift to operate correctly. Also what fuel pump do i use?

43mm is still a bit big and i would say 2x288 is also too big...

288 x 11.7mm is fine for "street & strip" on ITBs (or S/D) @ sea level.

The guys I know use 48-50mm ITB's and 300+ cams here in Jhb on their 16V's and are current record holders. These are drag cars yes. 288's and 45mm ITB's work quite lekker on street cars. If you keep the std long runner 16V intake mani then 276's work well.

[PoLonY]

oh ok everywhere i read on here everyone says 45mm etc is too big...I stand corrected thanks
