I know it can be done, by making the whole for the distrib, but I was curious if it had a spot for the egr valve, and if doing this mod would still be emmisions legal even if it had the egr on it. I tried searching for this but no luck, pics would be great also

Go to LT1intake.com

jovial86

You go to LT1intake.com










and you'll see theres nothing there I want to do an LT1 intake and head swap myself, but everyone says "go to LT1intake.com." Well, theres nothing there and I would definately like the info.

I did go to LT1intake.com and I have had the LT1 intake on my L98 for a year and a half. So no I don't have to go there. I was not aware that John was selling.

jovial86

From what I head John does an excellent job. And thats super for you... but doesnt help us n00bs out.

SydwayzTA 86

yeah i tried going to ltiintake.com
but he's selling

so given that you've had a lti intake on your car for a while could you just atleast tell me if a egr can be mounted still, and if it will be emmisions legal, thats the main part i need to know

Z69

It will interfere with the distributor, so no egr.
If you swap to an eDist it will fit. But that isn't legal either.
It would sort of be legal if no visual inspection is done in your state.
John@lt1intake.com still works for contacting John.
Till I make it forward to me. The soon to be owner.


edit;
Oxnard eh, You might be able to get a First Intake to pass if
you get rid of the logo. Too bad they don't work with a stock TB.

SydwayzTA 86

well i already got a nice setup going, with a ported plenum, slp runners and a edelbrock hi flo manifold, but if i was able to do the swap legaly i wanted to put a lt1 intake on

I have sold the LT1 intake conversion business to Scott Lopez (member Z69) and we are in process of transition. Keep chcking back at www.lt1intake.com for further information.

Thanks all for the last 4 years business. I hope you keep Scott as busy the next 4 years plus.....

im curious how much for??

iTrader: (2)

doesn't the lt1 have an egr valve on the back

why not fab up a pipe to mount the egr out of the way of the distributor and make sure everything is functional then take it to a ref and see if it will pass

A guy at work has a stock 94 LT1. I'll have a look and see what I can figure out.
I'll ask John too.
Might take a month or so for me to fab something up.

damn it i said im sorry about the pics... work(traveling from state to state) is really crimping down on my time at home.. i mostly post on this site from my lap top at airport terminals.. like i am now here in JFK.. sucks..

when i get back i'll do my best to take pictures..


if anyone wants to know what i used.. i used 2 45* 1/2" copper plumbers pipe.. 2 90* bends.. 1/16 gauge steel for mounting plates.. and i used the stock L98 EGR so the computer didnt freak out.. i JB welded the ends to the plates i made.. and this all moved the EGR over 45* from stock.. then up with the 90* bends.. which puts it perfectly next to the FPR, gives enough room for the distributer.. and plenty of room in the back area.. YOU WILL need to have the coolant lines in the front, NOT the rear if you want easier access to things.. its not needed, but it makes the rear less complicated...

then for the cross over tube.. i used a stock LT1 tube.. cut the end off where it meets the Boss on the intake.. added a 1/2 90* pipe to that, right at the boss.. so it take the tube up and over the valve covers.. this also makes room for the distributer hold down clamp..

when i take my vacation time in the next month.. i'll do a write up on it, so you guys know where to cut the pipes and what length.. its actually really easy since i already did the hard part.. which is test and cut.. test and cut.. totall money spent.. was less than 20$ including the stock cross over tube..

my only real concern.. is the heat from the exhaust going into the boss then coming out to the EGR.. the tubes are JB welded and it says that JB weld will hold up to 300*C, which is 587*F i would assume the exhaust is not that hot after going up a tube, then to a remote EGR, if not.. then i'll have to build the pipes out of regular metal and have them welded.. i guess we'll find out once i mount all this and start up the car..

i'll call my wife and see if she can take a few pics for me tonight.. since some of you guys are so impatient...

KiLLJ0Y

iTrader: (1)

wife was kind enough to take these... so im sorry if the angles are not good.. here is what she sent..


KEEP IN MIND.. this is not a finished product.. yes i know i need to notch the EGR boss.. and the studs are too long so i will replace them with bolts.. i have not had time to do the final clean up on these... but the adapters are done, just not painted and it doesnt look "pretty"

for those who will ask... yes i did all the mounting WITH the fuel rail on the manifold.. it does not interfere with it.. the EGR sits close to the FPR but still has room between it.. i measured the top of the EGR to the bottom of the manifold, and it will clear the firewall over hang by over an inch.. and does not come in contact with the wiper motor..

Great Job! Thanks for the pictures. That's a great example of good old TGO Members and their relentless desire to improve, modify and fabricate.

AWESOME ! YES ! thank you for postin those pics, thats what i needed to see, hehehe

Excellent work!

wow im kind of surprised you guys like my crude craftsmanship..i thought it looked like a$$.

there is alot of room for improvement on the design.. for instance the EGR height can be shortend down another 1/2 inch or so.

i forgot to mention but as you can see from the top view.. you will need to mount the distributer hold down boss a little more towards the back right. the crossover tube is right there and you wouldnt want mounting issues with it.



one last thing.. should anyone ask.. i didnt have an aftermarket adjustable fuel pressure regulator to work with...just the stock one.. and i know the AFPR are bigger in diameter, i dont know by how much.. BUT if you were to shorten the height on this.. it "should" be ok..

does anyone want a parts list? everyone i used is from HomeDepot.

There is absolutely nothing crude about it (let's call it, 'stage 1'). All it takes now is some vision from other TGO members to take you're concept a little bit further....

To be realistic though, it'll never be EPA approved.... unless you have millions to spend paying off those greedy environmentalist's.

Edit: Spelling

KiLLJ0Y

iTrader: (1)

true and true...

expect i dont expect to pass EPA... only a hick at the local smog station...

in all seriousness.. if i was a welder i would have made it out of metal tube..i just lack the tools to do some of the projects i want.. so all they become are card board replica's or something flimsy.

such as my functional SS hood cold air intake... circa '96 SS style cars

but if someone was a welder and could make this from steel pipe and plate... i would willing to send out this "prototype" to them so they can reproduce it in a more "appealing" way..


if anyone is interested.. let me know..

i have been using the LT1 Intake with my EGR for the past 3 weeks... no codes.. car idles and runs AWESOME!!! wow what a difference in power..


my engine consists of

L98 Iron heads, mild port clean up 1.60 exhaust valves, 1.5 summit racing roller rockers, 93 LT1 cam, LT1 24# injectors, 8mm taylor wires, GM coil, stock LT1 FPR, Hooker 2055 headers, 3" cat, 3" custom exhaust with flowmaster 80 series, custom made cold air intake, A/C delete, march under drive crank pulley and alt pulley, stock L98 throttle body, T-56 Tremec 6 speed from McLeod, 4th gen rear with 3:23 gears, LT1 Fuel Pump,

and All emissions systems intact, charcoal canister, EGR, AIR pump, ect.

damn this thing pulls like a bat out hell from 1500 to 5500 with no power loss till i hit about 5600... definately a huge power increase over the TPI.. i want to get this thing to a Dyno ASAP, but since i never had it Dyno'd before, i wont have any #'s to compair it too..

Bring it back to California Speed Way on November 12th and lets see how much did it improve your times. Show us a picture on how it looks under the hood.

ok... pictures i can do later this week when i get a battery for the camera.. not sure about the 12th.. i know i'll be down in thanksgiving time.. i really want to get to the track with it and see what its like.. i just cant wait to get the trick flow's and LT4 hot cam in there..


the Utah tech up here didnt even give it a 2nd glance.. he thought it was a stock LT1.. passed the sniffer and visual..

Z69

So the JB weld is holding up to the heat?

I thought your flanges were a little thin and would warp.

I may have to make time to fab one of these up.
I'd like to do it in SS but I don't have a plasma cutter.

The distributor hold down is put in that location because there is a casting reinforcement on the bottom side there.
So it gives a nice thick pc of AL to thread for the people that like to put 50ftlbs on the dist hold down.

KiLLJ0Y

iTrader: (1)

well i changed the flanges... i made them out of 3/4" of solid JB weld for strength.. and so far they havent seen 500* temps.. JB weld is strong enough for 500* F.. so i didnt think the manifold is going to get that hot...


and you're right.. they were thin.. thats why i changed it up.. what i wanted to do was make the braket out of aluminum but i really couldnt find what i was looking for to use...

Tobias05

hats off to you, great idea, sounds like you're quite a fabricator

KiLLJ0Y

iTrader: (1)

thanks for compliament.. but im no where near a fabricator.. i just got really bored.. and sat and stared at the manifold one day, thinking of ways i can put an EGR on there..

the ones in the pictures above are my "templates".. real fabricators would have used steel tube and proper metal welding to get the job done.. im not a welder or have any cool tools so i just used what i had available to me at the time..

my finished product is metal tubing, but where it connects the tubes to the manifold i used a block of JB weld and went to town on it with a dremel.. then painted it all black to match the manifold, it looks like a stock piece now..

Z69

There's a recycling yard off the east side? of the 5 or 91 as your heading south to Orange.
Might be SantaFe Springs.

I'd need to get an EGR valve and stock supply tube.
The flanges and welding are the easy part for me.

i have a spare L98 '92 EGR that im not using.. its a Genuine GM part i got from the dealer a while back.. cost new was 92$, was used for about 2000 miles... but i mean if you need one just to fab, then get a cheap one..

i find that using auto part store brands are not the same.. they tend to draw too much air in them.. and cause all kinds of problems..

i made a bottom template of the L98 EGR out of paper.. then transfered that to steel plate and cut it out.. you'll notice that 1 port on the EGR is rectangular.. so you need to use a tube thats about 5/8 in diameter.. same with the round hole.. needs to be at least 5/8's for the portion to slide onto the EGR..

i then also made a template from the EGR boss on the manifold, dont forget to notch the boss 1st, then make a template.. i then drilled a new hole and taped it since the existing one will be grinded off.. i did all this in about 5 hours.. didnt take long to get template made up, getting the correct angles to move the EGR over was a pain


the picture above will help show you what it needs to be,.. i used 45* angles for the ones that attach to the manifold itself.. then 90* to bend up.. do what i did and use plumbing pipe at first since its easy to cut and fit, then make your final

the only major issue is the wiper motor.. mine is pretty tight to it.. i could have made the height of the EGR tubes about 1/2" lower. hope this helps
