I was reading an old post yesterday.... N i read that when doing a turbo set up, that its best to swap the 95-97 2.2 motor for the 98-up 2.2 (2200) motor because of the fuel rail delivery or something... Cause they said if u use the 95-97 2.2 motor, u gotta make a custom fuel rail (not cheap 2 do) so it can handle the bigger injectors (390-550cc).... They said the 95-97 2.2 motor wont spit out the fuel correctly out the bigger injectors to give off that boost. Whats up with that?? I dont know if its true or not, thats why im asking..... Thnks ; )
It's true that the stock 92-97 injectors won't give enough fuel for more than about 4 psi.
The conversions are getting easier but they still take some work.
TBI has better chance at successful turbo swap than 93 - 97 MPFI! The injector has more room to deliver extra fuel.
You could look into additional injectors or swap to later engine.

so if i jus get bigger injectors n a SAFC, i should be fine??
Whats a TBI and MPFI??
Actually, you can do the injector conversion pretty easily. By having the factory injector bungs opened up on the factory manifold you can use the 98+ fuel rail and regulator, it just so happens that the injector angle lines up with the stock manifold on the 93-97 engines. A machine shop can bore out the manifold to fit the new O-rings, other than that you need to plum the fuel line to the rail. The downside is there's clearance issues with the throttle pulley at WOT clearing the fuel rail, so far the only solution I've found is to either fab up a spacer for between the plenum and the lower intake, or somehow modify the pulley to fit.
Emry was supposed to do a top feed conversion set up, or atleast a plenum spacer.
Here's Emery's conversion post. I was going to do the plenum spacer, but Emery beat me to it,
more info from my thread.
BTW, I need to get back with him about getting a spacer. I ran into some problems and had to put getting mine off for a while, but things should be better soon (knock on wood).
Yeah, I remember talking to him about it a time or two. Did he actually finish it?
The last time I talked to him, his machinest was on vacation, then my problems crept up on me and I haven't gotten back to him. If you look in my link above, he had atleast one made.
I do remember that. He had mentioned offering to make them for people, I gave it thought since he's here in Iowa, I could make the trip to his home town and pick one up, plus I wouldn't mind checking out his ride. He's what, 18 or something like that, and the kid seems to have a lot of talent. I never met someone that young that had the mechanical abilities he has.
I finished mt top feed conversion last year. Here is a
link
I designed the spacer on a 3d-cad machine, and sent it to a 3-axis lathe, and machined it out of t-6061 aluminum.
It came out very nice.
Enjoy. The guy let me use the machine, and gave me the aluminum block. :-)
I used 1" thick.
emry has sold all of his stuff last i knew. i was gonna try and buy it all but someone beat me too it. LoL.
anyways i am getting my local machine shop to just mill mine out for me. man he is charging me awsome prices.

yeah emry got rid of his car and sold his top feed conversion.
I'm 100% finished my top feed conversion but some would argue that its not the most economical way to do it. Also, the way I did it, I dont need to use a spacer.
VTLoki-nice job on that conversion and that spacer looks awesome. wanna do a top feed conversion for me?
Impressive. Are there any clearance issues if one were to install a strut bar? It looks pretty simple and straight froward. And was 1" necessary to get the clearance for the TB, or were you also looking for more plenum volume? Steve, just out of curiosity, how did you do yours? Because I was seriously thinking of going a different route altogether and building an entire upper plenum that would relocate the TB to the side like you see on most other cars. That way I could pick whatever TB I wanted, and I can build the plenum to the exact specs that I need, also as mentioned before, maybe try out some velocity stacks and things of that nature. Just something I've been playing around with, kicking around ideas a bit.

1" was not necessary. But between .5 to .75 would have worked. I only did a rough measurement, and the aluminum stock was close to 1". It may cause problems with a strut bar. I dunno about building a whole plenum. It could definatly be done, but you'd need a big block of amuminum to machine it from, and if it goes through the side, on my car, the brake booster would be in the way, and on the other side, the motor mount is in the way of an intake pipe. But, if you work out the logistics, anything could be done for the plenum.
I thought about this very same idea, just havn't gotten it to the CNC machine yet.

There was a guy in some of the boost forum threads offering an custom upper plenum with a top-feed fuel setup for like $600...looked pretty nice.

/ me goes and searches boost forum for this guy
yeah it was Todd that was offering.. Thats a wicked price for what you get.
definately anyone thinking of spending a little coin to do a nice upgrade, go through Todd.
I just looked at my ln2, and i don't think there is even a fuel rail on it. Looks like the rail is built into the intake manifold.
Can you put a 2200 intake manifold on, will the ports match up. My thought is to convert to a 2200 intake manifold, and use a custom fuel rail to link up a set of top feed injectors.
Any thoughts

IF you're going to build a custom rail, do it for the 2.2L manifold you already have. Actually, scratch that, don't bother with a custom rail on the 2.2L head because you'll have a hard time getting injectors to line up properly. No, you can't just throw a 2200 manifold on, but you can convert to a full 2200 head if you want, STFA for more info on that.
While looking through some old stuff that's collected on my laptop, I came across pics of Tony Gibson's setup and I now realize why he didn't need a spacer to clear the TB. He has the injector tips halfway to the bottom of the ports, which makes the rail sit a lot lower.

Has anyone converted to top feed injectors on this ride? And the 2200 is that still ohv? I thought 2200's were OHC.

Please do a LOT more research before posting again. Thanks.
You could start by reading the posts above yours...

For the D.I.Y.er, check out
Ross Machine Racing. They make Extruded 6061 T-6 aluminum intake manifold parts to make your own intake manifold.
Nice. I figured out a solution to the injector issue, and am now looking into parts to make a good intake. I've got a buddy who used to work for gm who has a CNC, and is willing to help.
