hi !!

what is it between the front lip and the radiator ?? the red cover , i think "ARP" is printed on it ......

[Rajunz]

The red part is the front radiator support. The chrome looking plate in front of it is a polished aluminum cover plate that I made to cover the Intercooler.

[projectsupramk3]

Nice job, it really is starting to get that muscle car look.

[Rajunz]

Thanks, see here I've added the front lip.

[tectyl]

is it possible to send me a closeup from the cover ???

best regards from peter

looks f##### nice

[r34-gts]

nice rims.

Very sweet ass ride, I bet you could blame a couple over-night pussy plans on that pup.

Damn my 87t will never look that clean, sigh... but at least my under hood view wont have that gimp ass IC pipe going across the engine. I don't get why people go all out on their supra and keep such a restriction as a poor flowing IC set up.

I chopped the stock plenum off of my intake manifold, and welded a 3 1/2" ID aluminium pipe on that ho, cut it in half, ported it with a digrinder, welded halves back together, then went to burnsstainless.com and bought a couple aluminium megaphone and cone transition peices(from turbo outlet 2" to IC pipe 2 1/2" : from 3 1/2" plenum to 2 1/2" TB), and three 2 1/2" mandrel bend IC pipes. [also aluminium, and everything all polished up ]
All that not only to have a high flow intake manifold and huge plenum.... but more importantly so that I can facilitate the use of an IC that flows straight through.

You don't have to go that far into it though, some sell such a creation on ebay.

The sad part is, my brother that does all the fab work for me, won't let me show ANYONE under the hood... much less scatter it on the internet. He says his pie cut turn technology (to make the angle line up with IC pipe) on the plenum is too aggressive to just release to public eye. Not to mention his self fab'd alternator relocation kit, using fucking turnbuckles and spacers made of pipe on one side, plus a support brace from engine block to rear of altnator!!! It drops the alt about 6 1/2", a must in my situation of welding the cone to the plenum pointing right at the back of stock alt position. And so now my stock TB(well its stock looking lol) sits where my alternator was.

God sent my brother to me... to build my supra...

I can't wait to get on the road and stomp the shit out of everything.

All of that pointlessness has what to do with Rajunz's car? Your making statements without facts to back it up, the stock 7M manifold flows very well and very evenly across all cylinders. The 3000 pipe is not a bottleneck unless you have an upgraded turbo, with any ct26 it is in no way a bottleneck seeing as how the turbo outlet is the same size. Did you use a flow bench to test your manifold? Did you do any calculations for plenum size and runner length? A bigger plenum is not always better as I'm sure you must know. The only thing you need to make the stock setup flow is a good IC and a set of hardpipes, spearco makes innercoolers with the in and out on the same side, top-bottom flow and they do it very well. Arguing about two feet less pipe would be rediculious, it will only take a fraction of a second to pressurize it. Congradulations to your brother on building one though, maybe one day he will share the pics with the mk3 community.

[7M > V8]

I never said the 3000 pipe is a bottleneck, i was talking about the in / out on same side intercooler... its 90 degrees of turn I eliminate. (i think thats a good thing, but hey what do i know, i geuss maybe i should try more bends/turns to increase the flow of my intercooler system)

Dude the stock plenum blows ass. I never said it had bad flow JackAss. Why bring all that pipe right across the top of your turbine housing??? I wonder if extreme heat comes off that thing? I wonder if heating your boost raises exhaust temperature?? Maybe im confused... you want exhaust/boost temps lower right?
It IS gimp, suck my balls retard.

And why cover up those sweet ass valve covers?

I did not re create my plenum for size but for position of TB. Yes my manifold is at the machine shop right now, being flowed / finished.

I'm not so sure i have shorter pipe runs. I never said I do.

My runners are stock, just cut stock plenum off and welded pipe on top for TB reposistion, and so i can have 90 degree's less bend in my IC system. But while i have all of the intake manifold off the car i match ported it, and smoothed inside of it from casting marks to babys butt, and am getting the ports in the plenum flow tested.

I'm using 62-1 trim on a ct26. which isn't a big upgrade, but I bet my dyno will be attractive. I can asure you I got 35 hp or more out of my change, that cost me all of about $200.

why flame me, i just dont get why people that deck thier car out dont go the extra mile thats all. I geuss you either just dump pile after pile of cash into your car and like it, or spend some time thinking of what could be a great improvement, that isn't sold in a store.

[projectsupramk3]

Very intelligent, the "suck my balls" comment was the icing on the cake and really made me see things your way, what was I thinking. So what your saying is you eliminated two 90 degree bends around the engine, and put two more on the other side of the engine going down and then foward. Sure you will get margionally lower intake temps by keeping half the pipes on the cold side but there all in the same tiny space which heats up everything almost equally. If you don't want the pipes going directly over the turbo then bend them away with a simple 45* bend over the plug valley. Either way I don't see why your standing up for the fad that is the FF manifold and bashing something that's been proven time and time again to work. I'm not flaming you personally, but you need to get your facts straight before you go making wild opinionated comments. Good luck with that 62-1 also, we have all seen how long a big wheel on a tiny shaft lasts. It's your car and not mine so you do whatever you want to it obviously, why should I try to help you spend your money.

[7M > V8]

I don't understand what your saying. Your first 4 sentences don't piece together in my head.

"So what your saying is you eliminated two 90 degree bends around the engine, and put two more on the other side of the engine going down and then foward."

I have 315 degrees of bend in my entire IC set up, I don't know what he has. Where i lose 90 degrees of bend is the IC itself... I don't really get what you are saying. looking at the car from the front to back, i have 2 90's on the left of the IC, one 90 and one 45 on the right side.

"If you don't want the pipes going directly over the turbo then bend them away with a simple 45* bend over the plug valley"

So your solution to keeping heat from the turbine off your IC pipes is to add 45 degrees at the stock TB position?? You would have to add yet another 45 angle in front of radiator then a hairpen bend to the IC. Thats 270 degrees right there, not to mention from turbo out to IC in(another 135-180degrees). You can also tac on an extra 90degrees from your in/out on one side IC. So a minimum of 495 degrees of bend (probably more) with your on the spot idea, a minimum difference of 180 degrees. Ok i think part of the point of TB relocation is to lower the degrees of bend in the IC pipe, and lower boost temp. Better flow and lower temp are good things right? Keep in mind this didn't cost much.

"I'm not flaming you personally, but you need to get your facts straight before you go making wild opinionated comments."

What are your facts? I can hardly make sense of what your saying. I will get 35+ hp off this cheap upgrade, that will be a fact.

"Either way I don't see why your standing up for the fad that is the FF manifold and bashing something that's been proven time and time again to work."

I wonder why the 1jz / 2jz intake manifold / IC set up is designed the "new" way. Come to think of it, another japanese engine renoun for quality the RB26 is also designed this way... the SR20det is too. I wonder why those famous engines are designed with the TB pointing towards the front bumper. Maybe because its better, or maybe because its dumb as shit not to do so.

"Good luck with that 62-1 also, we have all seen how long a big wheel on a tiny shaft lasts."

Couldn't make sense flaming me, so flame my turbo? I can't afford what i want yet.

Project, it's dumb, flat out dumb to not spend $200 on something that will give you 35+hp when you already dump ass tons of money into your car, like big money up top. We didn't have to ruin this guys pic post. I was just trying to understand why people don't upgrade, I geuss a little thought and a little running around is too much harder than swiping a credit card.

[projectsupramk3]

Alright this is my last try and then I'm done wasting my breath with you, its pointless that your so set in your ways you can't see another point of view. Since you don't understand the IC piping I will try to explain it though, the TB and IC inlets are parallel, so that means there can only be a 180* bend total, one 45 over the plug valley, a 45 at the AFM, and a 90 at the IC. For the FF manifold, you have to have a 90 down, then a 90 foward, incredibly making 180*. The turbo outlet piping will be the same FF or side intake manifold, and your IC problem is solved with a simple top-bottom flow IC, the pipes are on the same side as I've already said a few posts up. If you want to cry about facts then where is it proven a FF manifold will add 35+hp over stock? Yes I am going to flame that turbo, it shouldn't be made and it shouldn't be sold to anyone. It's only a short matter of time till it blows or snaps the shaft, save your money and upgrade it the right way, but again if you think I'm flaming you and not trying to help then that's your right to look at it how you want. A FF manifold will not cost $200 to 99% of the Supra community, the veilside manifold for the MKIV is almost $1K, 7M FF manifold kits using a stock MKIV manifold is close to $500, not everyone can fabricate whatever they please like your brother and myself. Again, if you want the manifold to clean up the engine bay or for the wow factor thats fine, just don't expect huge gains unless someone spends alot of time on a flow bench with it, don't expect a huge drop in intake temps, don't expect a huge gain in throttle responce. Money can be better spent elsewhere IMO. Good job to your brother for fabricating it though, I look foward to seeing some pics of it.

"Since you don't understand the IC piping I will try to explain it though, the TB and IC inlets are parallel, so that means there can only be a 180* bend total[false], one 45 over the plug valley, a 45 at the AFM, and a 90 at the IC."[impossible]

I'm sorry but my brother an I both agree that this is a false statement. You will have to have another 90*. Just because they are parallel does not mean there can only be 180*... i don't know how you come up with that. If you don't understand that your statement is false I don't know what to tell you. Did you think before you posted??

45* toward radiator, then the other 45* will point the IC pipe toward the right headlight... still leaving you with a 180* bend to solve. I mean you do realize that if you eleminate the 3000 pipe and put a 45 off the TB you will put the path of your pipe headed directly to your radiator, unless you cut a hole in your radiator you have to make that 45* turn towards the headlight.

"its pointless that your so set in your ways you can't see another point of view."

it seems to me this portion of your post describes you.

I have enough pvc to make a mock up of your wack sugestion. I can make a pic of my current mock up, and one of your random idea if you like. Your "fact" is false. Don't waste your breath posting partialy thought through ideas.
