i have a jay tech lower manifold. and am using a 4 barrel throttle body like this one...



but mine has no place for fuel injectors. so iwas thinking of injecting fuel this way...

either getting a 2 inch spacer and tapping it on the sides for injectors like in my crappy paint picture. or getting two 1 inch spacers, and welding in some aluminum sheet on the sides to lift them apart, and adding the injectors on the sides again.

any problems with getting my fuel this way? if you have a better idea, let me hear it...

If you have to get stuff welded, why not just weld injector bungs to the intake mani itself?

i dont really want to drill the cast manifold. i thought about that at first. but didnt really find a spot i would like to put the injectors on the manifold either...

plus i do all my own welding. so making it is no problem.

also one like this... http://www.jegs.com/p/Moroso/743744/10002/-1

Why go thru all that trouble when you can get that allready made with the fuel rails , here is a site that sells it part#JT800http://kgparts.com/index.php?page=jaytech

i've contacted him many times already in the past two years. no responses at all. and have been told by other people none of those products are being made any more. plus when they were bing sold, the prices were ******* crazy...

what trouble though. it would take me 20 minutes to drill the holes and weld on the injector bungs. and with the Moroso 2" spacer only being 65 bucks. dosnt seem like a bad alternative.

so has anyone run one like this? or any other ideas?

Well it sound like your are looking for the most sheep way around , just do like Doc said weld some bungs on the Intake it self and make the F/R and be done with it ! Take it to GATO He'll make it for you , you are near him.

i dont need Gato. im a certified welder myself.

what do you mean by sheap? cheap??? im not trying to do it the cheapest way. thats why im asking if my idea is any good. but what i dont want to do it tap the manifold itself...

i wish i had the TB with the injectors already in it like in the pic i posted. but to late for that now...

If your not trying to do it the cheapest way then why don't you get the correct throttle body?

iTrader: (10)

well, im not rich. so i cant just blow another 700 on a second throttlebody...

Well since you dont need Gato and you are a Certified Welder and you are not CHEAP , There is only one way to find out if your idea works thats call trial and error and see how mutch money you end up wasting . What works for some dont work for others !

https://www.rx7club.com/race-parts-only-228/full-custom-intake-manifold-set-up-sale-762203/ Looking at this build I could only imagine if you wasn't cartified and when the welds done right thet don't need to be ground down for a better look ! I have never seen a custom Intake done by Wilson , Gato and all the rest of the builders with the welds grounded off.

Oh by the way having a welder and knowing how to use it doesn't make you certified

GoodLuck and keep us Posted

yes trial and error is the correct way. but i am just trying to get some ideas going. but people like YOU make forums like these hard to do that. becuase if its not YOUR way, its the wrong way.

that manifold was made over 2 years ago! before i went to school for welding/fabricating. i have since cut it up and remade one. I did that old crappy one with MIG. becuase back then, i didnt know how to TIG. I have my certification for Stick, MIG, TIG and Flux cored welding now. and have passed both bend and x-ray tests.

******* internet know it alls...

this is going know where, i'll do it my way. it will work just fine...

I never stated I know it all nor think I know it all , Life is a learning process each day . All I tryied doing was help you with a product that is offered from a retailer similiar to what you were thinking on making !

Back 13yrs ago I my self was a certified welder for a manufacturing co , use to tig and heliarc and was offered an oppurtinity to get underwater welding certification but was not something of my interest good money but also dangerous . now I only do it ofr my self and family

If you were so sure it will work fine , why you post for opinion n the first place?
Who sound like they know it all now?

I myself would have the injector & bong at a 45 degrees instead of 90 , just a frendly tip . Hope it work out for you

If you only plan on running 4 injectors in my opinion you should put two in the factory location on the center iron and weld two bungs in the secondary runners of the manifold. On my last intake that's what i did. Running the injectors that far away from the motor might cause idle problems. I have some pictures of both of my intake setups but not on this computer. Shoot me a PM next week and i can send you the pictures if you're interested.

Here are some pics of my current setup. i will post up some pics of the old setup later. The old setup actually had bungs welded into the runners.

Many many years ago, Jayect had a "plate"' just like your drawing, I am not sure if they never mass produced it or if it w'plateasn't a popular item. Once thing is for sure, I've never seen any vehicle with that "plate"...

For less than the custom bungs, injectors, and fuel rail you can get an auto-nomics (www.auto-nomics.com) throttle body with everything (400 ish). I did the math a few years ago, but there was no way to do it on a tighter buget. The base TB with no injectors, no rails, no IAC ect was like $70 a few year ago so if you already have that stuff it could be super cheap. As always you get what you pay for, but it worked for me. Below is a picture of mine. The throttle shafts may leak depending the boost you are running, but there are many easy fixes you can do of cheap (see second pic). I run 15 psi with no leaks. I run 6 injectors, four in the TB and 2 on the block and drive it daily to work. The other guys on this forum will know more about race applications but I figured I'd give you a heads up any way.

damn, thats a nice daily driver set up. what CFM is the throttlebody? hows your throttle responce with it over the TII manifold? and can these be modified (like a carb) to flow better?

nice find for the price.

sen2two

iTrader: (10)

damn, now thats a dope set-up. that the E&J throttlebody right? wish i has went with that one. i might sell mine to my brother, and pick up the E&J one. it is so nice, and i wouldnt have this problem.

Supercharged FC

The TB is 750 CFM and I think it can be bored out to 1000 cfm, check out the web site to be sure. Never ran a TII intake to directly compare, I think your turbo will have more to do with responce than the TB. When I hit the dyno I'll post the results and compare them to my friends with the TII intake.

I need that, where did you got it from?


I tried the plastic one that summit racing sells, but the fit wasn't tight, and air leaked from the TB and also from the hat

Thanks.

I do recommend the E&J setup That should take care of all your problems!

I use to help make those intakes a few years back and i do not recommend drilling or tapping those intakes. some of those intakes were inconsistent on wall thickness and would easily break with a few pecks from a screw driver especially at the bottom of the runners. check it!nothing worse than it blowing out and leaking fuel on a hot turbo mid pass...

Is it a tight fit on both sides?
