A Walbro 195 fuel pump would be enough ?
A: Depends How Much Power You Extract And What Are You Needs.......Even To Some Extent Stock Fuel PUMP Will Work Also With AFPR But Its All About How Much You Need.......195LPH Will Be Enough If You Keep It Around 1bar
Should i bore out the 4A-FE block from 81mm to 83mm Stock 4AGZE pistons,
A:: Why??? 4AGZE Also Have 81mm Piston ..Depends What's You Block Condition..Then Piston Fits Accordingly (Over Size If Needed)
Where could I source the rod's and pistons from a 4A-GZE ?
A:: Interesting Question...Simple Answer Is Junkyard or You Need To Order A Set Of NEW....You Won't Be Finding 4AGZE Stuff That Easily...Some People Have Block Of 4AGZE...You Can Check PW
I don't want to go Turbo ATM. Ill build my self a 3S-GTE AWD Corolla later on.
A:: That's Your Choice But Forget A/c With Supercharger Inside.....Even If Somehow You Do......It Will be An Issue Specially With Belts Alignment....4AGZE OEm Setup Is What Can Guarantee You Most Reliable Setup In This Case.....!!
Right now i Just need to get hang of the car with low boost levels. Ill gradually keep increasing in power. Ill take the supercharger to 1 bar. and if i dont feel good with it ill get a turbo conversion done.
A:; Always People Choice What You Like But I Wound Suggest Not To Mess Around So Much ...Do It Once And For All.....! Money Ain't easy To Get And Most IMP Time Also.......Its Not As Easy As You Think.....Swaps Will Take ARM's And Leg's To Complete And Run As Wanted..
Twin charging looks like a hassle there would be not to much space in the engine bay for too many pipes.
A:: Just A BIg NO
What if the mixture is too Rich ? would that cause a problem ?
A::: Black Smoke.....Carbon Deposits...Low Power....Most Interesting....TOOO Much FUEL Refills......Makes Petrol Pump Your 2nd Place To park....!
