hey peepz im keen to know if an r34 gtt fuel pump would be classified as a direct upgrade and if it would easily enough???
also would it be able to flow more fuel??? and could it be directly wired up without having to re-tune my apexi safc....
i want to run atleast 14psi of boost from a r33 turbo on my rb20det with front mount, full exhaust system, safc, pyrometer, electronic boost controller....and i will be adding a adjustable fuel pressure reg and hence the reason asking if it would be of benefit to get a r34 gtt fuel pump....?????
AND THEN RE-TUNE THE SAFC!!!!!
