Got the new motor in today. everything fits...FINALLY! haha... It's all bolted in and connected to the trans again. What a fun job that was by myself lol. Oh well wasn't that bad. Some final shots of fitment and the vast amount of space i have now :)

 

engine bay space!!

the tensioner bracket i made to clear the filter, cant really see it but it has a big C-shaped curve in the middle so i can still thread the filter in and out. Just filled the bar on one side with weld and ground out the other to fit around the filter.

alternator is tight... i think ill make some custom brackets for this one too later on to bring it in closer to the motor as well but it's fine for now, it fits!

I couldn't be happier with them! So far so good they look amazing. the TIG welds are phenominal, i worked as a powdercoater for years so ive seen a lot of pro welds and these things are among some of the best ive seen. ill get some pics they look flawless. the flanges are double seam welded and then ported on the inside. very smooth transitions.

but yes, no y pipe and they dont even go close to the stock y pipe, they shoot way further back , especially the passenger side so custom work need be done to make them fit.

 

quality of the product though, they are amazing. especially for what? i think i maybe paid 100$ shipped for them brand new! my buddy who builds v8s said he would have to pay 1000-1500$ for a set of headers of that quality for his v8s lol.

i just ran outside with my gauge, the primaries have ID of 35 mm (1.4"), although they do flare out just slightly right where they meet with the exhaust ports out a little bigger maybe 36-37mm tops, the collectors have 2" slip joints on each end.the OBX headers come with really nice compression clamps as well if u just want to utilize the slip joints, they look solid and shouldn't leak.

 

got the front diff back in today. man that sucked lol, even with 2 people it sucked. last of the heavy stuff is done though, it's all tinkering from here. so happy to have the majority of this swap done now.

sorry buddy you are lookin at it in the pics, i used the old vg30e adjuster to make my vg33e adjuster. cut the ends off end welded them on the other side so they would work on the opposite side of the motor. i do remember off the top of my head though that there wasn't any offset in the bracket, it was just a straight piece of steel. im sure someone else on here can help out with a picture of an un-chopped/welded/ground adjuster lol.

okay so for whoever wants here's some pics of the headers install.

 

there was a small bracket welded to the frame that led to nowhere and I have no idea why it was there. nothing was attached to it and it was in the way of the passenger side header, so i cut it off. it was right by where the trans cooler line comes out out of the trans on that side. after i lopped it off, smooth sailing!

the driver side header isnt seated fully yet, there was a little bolt in the way that holds on the dipstick tube that is different for the vg33 (headers were for the 3.0) but it is literally about 1mm contact, ill grind it tomorrow. they do fit very nicely.

the angles end up being pretty good to make up a Y pipe

keep in mind i do have a 3" body lift so getting them in place might be different for you!

hey no problem man glad some of the pics could help you. I am putting an r50 motor into a 93 as well. We are doing the exact same swap! haha. How are you doing it? Using your accessories or the r50 accessories?

the truck already had a dual exhaust when i bought it but i am taking it out... just more to break on the trails and i want the room later for turbo and air tank. :) im running into a y pipe flared out to 2.5 inch to a side exit.

 

 

the run for the Y pipe into single flows better anyways its a much shorter run and much more straight. this truck only has a single o2 sensor which would have to be put in a crossover pipe. so the 2 pipes must meet (which they didn't before) at some point (and they should anyways). once you re-route the second pipe back over to the other side after the crossover it ends up being a big jumbled mess. lol. the guy who had the truck before me had 'true' dual exhaust with an o2 sensor only in one pipe... im sure that is not good either lol. anyways yeah you will see how much better flowing the single works out to after the pipes meet up at the Y. I got it all planned out

the vg30 if possibe. im trying to mix and match parts form a vg33, vg33e and a vg33i

 

 

vg33 and vg33e are the same thing. there is NO vg33i unless you build one.

 

vg - designation for that series of cast iorn block.

 

33 - displacement, 30 and 33 available in the usa other numbers were custom builds; 31> .060" over pistons; 34> a 33 bored out to 92.5mm to use Q45 pistons

 

e - multipoint fuel injection (mpfi) this letter is often left off when describing a vg30e or vg33e engine.

 

i - throttle body injection (tbi) only 2 injectors. only came stock in vg30i form 87-89 w/d21 this letter is also often left off.

 

also the VG33 used different tentioners in different vehicles.

well there's no contact with the pipes to anything else. though they definitely take up more room than the stock setup! haha. the driver side header is not quite sitting exactly where it will be in the end either as the flange isnt quite seated (need to grind about 1 mm off of the edge of one of the flanges). There is a bolt that holds on a mount for the oil dipstick tube that is different on the vg30e. It would have fit if i still had the vg30e. Will be about 3 seconds with a grinder so not too bad, ill get another pic up once the Y pipe is done. :)
