im thinking about buying one of these to replace the tpi setup i just installed on my twin turbo iroc

long story made short is

car was originally a l98 tpi car, previous owner swaped in a 355 with carb, i bolted oon a tpi with a megasquirt and twin turbos

im not happy with the tpi though the setup works great and turbo'ed tpi's have gone low 9's but im looking to go into the 8's and its just going to cost to much to upgrade the tpi setup to get there

engine is 9.2-1 cr
ported 882 heads
224/224 @ 50 cam
twin t3/t4 57 mm turbos .63 hotsides with stage 3 turbine wheels

im thinking about getting that intake and using an intake elbow with 75mm tb

 

Not bad, the center bolts have already been elongated. Excellent price to boot...

 

I just built a 406 SBC with one of those, but it was the polished version.
Its a nice piece, seriously. the ports are very big, much larger than the edelbrock. From the TB/carb opening you actually have a line of sight to all the ports, so you can actually check the port matching visually. The ports were VERY close to the factory ports on the world products Sportsman II's this engine has. The gasket size is a felpro 1205.
I have not run it yet, its a family members streetrod project and I'll have to go finish the wiring this summer. I bought blank fuel rail from a guy on Ebay for 11 bucks a foot ( a 3' stick will do fine) and made the fuel rail brackets with 4 pieces of 1/2" round1" long aluminum with a 1/4" hole. I re-tapped the hold down's to (IIRC)1/4x20 since the factory thread size seemed inadequate to me.
I would buy one for my own engine next time I build a small block.

BTW, for the center bolts it comes with some little inserts for straight or angled bolts.

 

8's with your setup? I'm looking to get 8's on my setup

But that intake is similar to my single plane EFI... victor E EFI. SHould work great for you. Works great on my mild 400. Fuel distribution looked pretty even when I tore the heads off and looked at the pistons and plugs. Good intake IMO.

I run a 90 custom intake elbow from 6061.com but it has a divider in the intake to help even flow to the manifold plenum. I think it works.

 

i found the polished version its only 10 bucks more so ill prolly get that, i found a profesional products fuel rail kit that will fit this intake for 50$'s comes with both finished rails with crossover tube and feed and return fitting

yes 8's im not afriad to push boost levels into the 20's on mine + i have the 2 stage nitrous system on the car, hell i should have enough turbo to do it without the nitrous

how did u hook up the throttle cable did u have to make custom brackets or something, and do u have any pics of how urs is setup ?

 

yeah made my own bracket using a factory GM 98-02 throttle cable and matching throttle body. I dont know exactly what year TB as there are 2 different part numbers for 98-00 and 01-02 I think but you can get an intake elbow with bracket already welded on from 6061.com I do believe.

I had him make me one with 5 vacuum ports on the intake to my exact dimensions but forgot to have the bracket welded on...i figured it came with one but it didnt.

Heres the elbow when I first got it


Only pic you can kinda see, but I took a piece of flat bar steel, about 1/2" to 5/8" wide, maybe 1/8" thick. Cut 2 pieces off. Drilled hole on one end, welded them together in a 90 deg L shape. Notched the top of the L with a cutoff wheel for the throttle cable to slip down in. Took another small piece of bar to triangulate the L for rigidity. Works well. Thing bolts down to the intake top

 

where did you get the fuel rail kit for $50? When I was looking for one it was a lot more, at only 50 I wouldnt have did the rails myself.

 

Pretty sure he's talking used from somewhere, because the Professional Products fuel rail kit for that manifold is much more than just fifty bucks...

found it on ebay it was like 53 bucks + 20 shipping, ill prolly just buy the fuel rail extrusions and make my own though i think the ones i found were -6 and i want atleast -8 rails.


anyone need a stock tpi intake lol

ouch man 225$ for an intake elbow i think ill make my own for that much

 

Victor E rails are 80 bucks and are -8 sized...well I dont think they are -8 o-ring threaded but you can get the -8 to 9/16" or whatever thread size they are. I have -8 line feeding my rails with -8 crossover into -6 return.

yeah the intake elbows are little pricey. I could easily make it for much less but I cant weld aluminum so cost of having someone do the welding just doesnt make it much better than just buying 6061.com's elbow

 

id have made one out of steel before paying 225$+ i dotn have a tig welder anymore but i do have access to a stick welder i can do aluminum with. ill just buy a 1/2 thick carb spacer and pick up some aluminum and make my own

 

The elbow is pretty cake... I actually made one out of cardboard and used that as a template for this design. had him copy it. You can buy sheets from tractor supply or other hardware type stores that sell raw material.
Steel would heat soak too much I would think....

Thats one thing I wish to learn is sheet metal fabrication using aluminum. I could easily have made the form, just couldnt weld it shut. Boost probably blow it open

Only tricky part is making a flange for the LS TB...all you'd have to do is cut it right shape and drill/tap few holes for the bolts. I dont like drilling/tapping holes.

 

i dont think a steel elbow would get hot enough to do any harm im willing to bet the base of the aluminum manifold would get hotter then a steel elbow

 

I also dont think the steel elbow will give you any heat problems compared to an aluminum one. The biggest difference with aluminum and steel in this case is how fast the heat transfers from one end to the other. Both will end up warming up to almost the same temp as the intake manifold.

 

I do know my intake gets hot since my coolant temps are hot...plus it gets heat from the block/oil/heads. I use steel on my intake pipes and they get warm and stay warm...i was thinking of the cooling rate during rest periods in the pits at the track Aluminum cools faster. Oh well, kinda late for that now but I was considering a smaller cowl hood which would need a shorter rise elbow...so I could make it out of sheet steel perhaps... decisions.....

 

it wouldnt hurt to try,a steel one wouldnt cost but 20-30 bucks to build, and if it does get to hot u have a perfect part for somone to match and build u one out of aluminum

 

How you doing yours? 90 deg elbow and a throttle body or a carb hat on top of a MPFI throttle body of some sort?

 

90* elbow, i wanted to do a 4barell and carb hat but its way to costly.cheapest 4barrell tb with tps and iac could find was around 650 + the cost of a good carb hat

so elbow and lsx tb will be alot cheaper

 

I just use a LS1 throttlebody. stock no porting no nothing the sensors cost more than the TB itself

 

damn really, i plan on using the ls tb but i never know what i may find when im in the junkyard lol if i find osmething else that will work that i can snag for 10 bucks thats what ill end up using

 

Lsx trucks have them too. Ford TB's can work too, i think they are 90mm off the trucks and you can adapt it to the elbow if you are making your own. Heck if you make your own you can run whatever you want really. Nissan trucks or toyota trucks also use a big single I believe...i'd have to check that out. Mine is only a single 78mm. I'm going to a 85-90 mm eventually with 3.5" pipe to the TB but thats down the road.

 

have you looked at an Infinity Q45 TB? If you just want an inexpensive oem piece I dont know of anything bigger, and its really well made. The bore is around 79.5-80mm and has a neck that will hold a hose well when clamped, unlike the "easy blow-off" LS1 style. You still have to add an IAC someplace, but thats easy. The flange is a 75mm square pattern. One other advantage of the Q45 is it has a very nice roller-cam progressive linkage. Runs $20-40 for a road tested unit at pick-n-pull.

Here's a link to a car with LS1 type engine using the larger Q45 TB.

I have never blown off my intake coupler at the LS1 throttle body, its tight T-clamped. I have blown off couplers on other cold side pipes that were not bead welded around for a lip.

But I was thinking of that Q45 TB...I knew nissan/infinity or someone had a truck type vehicle with a large single TB that could work.

 

i picked up accels ProRam. got mine with the rails (looks close)
using a Lingenfelter Elbow with a V1 Ttrim. on My 427 sbc
intake and rails $505
(AFR 220 Elmtr Heads)

http://www.summitracing.com/parts/ACC-74139/?rtype=10

accel boxed
marked Motown/world prodcts
and having a taller carb Ht then the one in above pics.
looking forward to the install

this is the intake that I have. but all set up w/rails

I know they have a v8 truck, but I'm not sure if it comes with the 80mm TB (some sites claim its 90mm, but thats at the mouth, not the blade). But it DOES for sure come on 90's Infinity Q45 sedan (the V8 infinity).

 

I'm thinking of something else...I thought the Q45 was a SUV type vehicle.
