First off, you cannot change injector size without compensation. Second, how the heck are you maxing out your injectors on a n/t?

Hello,

A friend just gave me 1995 #00gt injectors, the read SDH-210. IMP-532, can I use these in my 98 GSX.

You really shouldn't use any OEM 3/S injector in your car.

Assuming for now that they are direct replacements (that is, neglecting any low and high impedance differences), those numbers indicate a non-turbo 3/S injector which is smaller than even our non-turbo injectors (210cc vs. 240cc). Even if they were turbo 3/S injectors, you really wouldn't want to run them as they are smaller than our 1G auto turbo injectors (360cc vs. 390cc).

Thank you very much for the reply. I was reading a 3gt forum and found out that even the vr4 owner upgrade to our 450s.

I also have some precision's with a pn of 041-0651, they are supposed to be for domestic, I think for camaro, they flow 65 lb of 650cc, disk type hi impedance, 14mm top and bottom. I don't find much on them. If you know anything about them I would appreciate it. I am waiting for my 255 and fpr so I will try them and find out if I don't find something on them that tells me not to use them.

Jokerman..I do not see any tuning or mods in your profile..So I'm afraid to tell you, you can't just swap in different injectors, and a 255 pump..For the 255 your gonna need a afpr, and to compensate for the bigger injectors and different fuel pressure..Your going to need somehing to compensate with..

Wich means safc, ceddymods, or dsmlink..

 

[jokerman]

Sorry about that, I do need to upgrade my mods. I an running a dsmlynk 2, Injen intake, tubular exhaust mani, 20g turbo, I am waiting for an fpr and the 255.

If you get injectors that you don't have to tune for, that means they were not an upgrade.

 

[Bud92gsx]

Then you should be ready to add bigger injectors, and tune accordinly..If you can wait a couple weeks for injectors..There will be some great black friday deals going on..

Also I would contact ecmlink, and see about an upgrade to v3..

Its a slow process since I don't even have a job. I am getting this from friends and familly. Thanks ofr the help. I am also selling some stuff to get a wideband.

 

[Bud92gsx]

Shouldn't you have gotten a wideband when you installed dsmlink..

I didnt do it I got the car like that when I bough it. I am starting to try and finish it. It was running good and the fuel lines were right before I upgraded the manifold and turbo, now it tells me is running lean, I dont want to tune or mess with it until I get this other stuff installed. I also put in a turbonetics mark 2 external waste gate.

I am not a newbie to this but far from an expert, it is my first turbo car. Any suggestions, advise I always take.. Many of you have helped me out and I been learning little by litle.
