Would an HX40 be too much with stock injectors? Or should I just wait and do injectors and a turbo at the same time?

I did injectors first, drove it a few weeks, and now just finished the turbo.

I felt the '93 was short on fuel from the get-go... my '90 non-IC spoils me with bigger injectors and smaller turbo. So it only made sense to throw more fuel at it first.

Wanna do a group-buy on pyro's?

Hey Guys...thought I'd jump on this wagon rather than start a new post....

I too am looking to ramp up the stock motor....I have already done the pump turning,

I am looking for what injectors to swap in and Turbo to upgrade to....I am looking for around 100hp increase over all....My motor is getting swapped into a 65 Ford crew cab 4x4, and it will be a daily driver and tow rig....I am sticking a Clark 5 speed behind it, so power won't be an issue thru the trans....

I am thinking HX40 Turbo...Is my stock turbo t3 or T4.....?

with the HX40, what would be the best bet on injectors....?

I will be running 4" exhaust as well...

Thanks for the Info, and sorry of the post hijack...

John.

i really liked my WH1c. made good power down low, you werent going to win any races with it but it was great for a mild build engine. i have nothing bad to say about it really. good cheap upgrade over the H1C

WH1C/HX35 56/58/12
HX40 60/65/16 laggier but will support more up top
an HE351 60/60/9

and i ran 5x.012's for a long time with the stock turbo had no problem clearing them up. temps were well into the safe zone

Depends. Do you want to use that extra 100 HP while towing or just down the strip? If you just want that 100 HP for the strip or stabbing the throttle at green lights, you wouldn't need a turbo upgrade but one would definitely put you over with the right fuel mods. If you want 100 more HP that you can use towing, make conservative fuel mods, increase your turbo size, exhaust and air intake size. 100 HP over sock isn't to hard to do, even to do it right. An HX35 will support a 100 HP increase for towing with the right exhaust housing

What size exhaust housing does the waist gated H1C come with? I know the common H1C non gated housing size was 18cm^. With that size housing, an HX40 wouldn't be much "laggier"

not compared to a h1c and i think maybe its a 21cm??? no quotes there. the h1c suck all the way around anything is an upgrade, 40's have weak shafts and a prone to break if you bark them. the 35's break to0 but not as often.

the 91.5 (1st intercooled) was the 21cm. 92 started the 18cm's, probably around mid model year.
