I've a Sierra dohc converted to 16v using Scorpio head and also turbed it. Injectors are side feed and is not easy to find good options as with top feed ones. I've tried injectors from skyline (around 370-390cc) but they are not big enough for my boost. Now I'm using injectors from 2.9 24v Bob (removing caps they convert to more than 500cc), but again not enough flow.

I want to convert it to top feed injectors. As now there are new Bosch options not very expensive. I can buy new 1000cc ones for not a lot of money, making me capable of more boost and e85.

Anybody now if there are any engine fuel rail than can fit mine? Rs2000 Scorpio have the same head but again side feed injectors.

Custom billet option.

Would like to see more car pics and engine.

I think it could be the best option, I've to look if there is some place I can buy the rail and injector bosses in mild steel or contact my local lathe man to help me making one



the car is a 3 door 2.0 dohc 92'.







turbo is borg warner EFR 6258, should flow like a T34, but very responsive, like the t3 from 2rm cosworth I had before. Now using boost of around 15-18 psi. I hope to being able of going to 22 psi when changing injectors



engine has forged pistons from C20XE which resumes in near 8:1 CR and forged rods





custom exhaust manifold




I would like to do also a new inlet manifold, as this is masive and it's difficult to do some operations on engine.

for managment, megasquirt MS2

brakes:
front: cosworth 2rm 4pot
rear: scorpio cosworth (vented like cosworth 4wd)

diff:
supra mk3



suspension:
gaz gold

diff and suspension installed last month, didn't tried well...


IC is one RS500 style from ebay, looks worst quality than the pace I've on the cossie, but the numbers on the inlet temps are very good. better than 2wd cossie intercooler I had before. Probably because my boost is low.






I've also a cossie 4wd, but what I like from this engine is that is really cheap comparing with the cosworth and it's capable of making 250-300bhp, which is ok for me on this car (rwd). I've to find the limits of the RWD MT75 , I've broken many conrods before installing the forged ones, but no only one gearbox

I really like that very cool and a good job. Those engines are bullet proof.
