Thread: Hiport Or Lowport

so what do you guys think is the better option out of the two. are there any pro's and cons to either one

reason i ask is my p10 at the moment is a hiport but im not sure whether to do my all motor build on my spare lowport

what do you guys think??

Seriously, lowport.

Flows more than a highport head. Period.

Highport easier to work on, but like he said lowports flow better.

Highport to high port will be the easiest to swap if you already have a high port in the car.

Low port will flow better, but unless your boosted, it shouldn't make that big of a difference.

Easier to stick with whats in there.

And the head will make a difference, stock vs. stock they have the same hp but add the highport cam (which should of came factory) and you got another 8hp.

hi ports do not have the hydralic lash adjusters perturding into the intake ports like the low ports do. This disrups the airflow to the head alil bit. nothing a maching shop or do it yourself tools can't handle.

The UK eGT engine actually got the highport cam as stock.

hmm ok. totally unexpected that. i'd have thought it would all be in the name.

has anyone here had a go at fitting carbs?

Try Payu in Peru, he has done it already.

Another vote for lowport here due to much superior head flow. Around 190 cfm for highport and 240+ from lowports unmodified.
