Nilz90 Posted June 4, 2018 Share Posted June 4, 2018 Hi guys I have my starlet gt turbo booked in for a remap with TD. It has a td04 turbo on there will be fitting a frp and emanage ultimate. The car has standard internals. I was wondering is it worth upgrading the injectors too? I found two sets of spares I have. Denso 23250-70080 312cc injectors Denso 195500-2020 550cc injectors What do you guys think or better to leave it standard. Quote Link to post Share on other sites
ashbuxton Posted June 4, 2018 Share Posted June 4, 2018 In my opinion there is no need for bigger injectors if you plan on running around 1 bar or under mate. I run just over 1 bar on td04 standard internals and had no problems so far. If you want to push anymore than a bar I would reccomend bigger injectors but lots haven’t bothered and is not essential.

5T4R7ET N/A Posted June 6, 2018 Share Posted June 6, 2018 Your probably pushing the standard injectors pretty hard at 1 bar, also if you plan to go for more power later on its future proofing them. The standard injectors will be at least around 20 years old now, i would upgrade, but only if you got the right management to go with it Quote Link to post Share on other sites
gorganl2000 Posted June 7, 2018 Share Posted June 7, 2018 (edited) if you are going to stick to a stock td04L...then you can get some mazda gtx 360cc injectors 195500-2130 or toyota 370cc injectors 23250-74160 ----the latter probably have a better spray pattern, but both will work and will require tuning and will meet the needs of any boost u run on a stock td04l if you plan on hybrid td04l or td05 later on, then get mazda rx7 460cc or 550cc----------the latter are not the best to tune at idle due to old design http://www.toyotagtturbo.com/community/index.php?threads/interchangelable-injectors.58014/ luckily we have some of the newer type Subaru WRX/STI available now as well, 420cc and 565cc---easier to tune with better spray pattern https://forums.nasioc.com/forums/showthread.php?t=1218460 PS. try to avoid fake/cheap non-genuine injectors Edited June 7, 2018 by gorganl2000 Quote Link to post Share on other sites
00joeindastarb0 Posted June 7, 2018 Share Posted June 7, 2018 RX8 yellow injectors seem to be favoured by mx5 owners, they can be picked up cheap and have a good spray pattern Quote Link to post Share on other sites
