Damn, I forgot how much NA sucks. (new intake manifold thread)
2 Attachment(s)
I finally got around to installing the intake manifold I made. Well, it's mostly installed...there's a few things that have to be redone (water bottle catch can FTW) but it's in and the car runs.
The whole point was to be able to run the intercooler pipe thru the fender instead of between the radiator and the engine. I couldn't figure out how to do a decent sized over-the-radiator pipe while keeping A/C. And I had to teach myself how to weld aluminum. :bigtu: I didn't have the time to do the intercooler pipe so I removed the turbos. Thanks to Paul for lending me the RB 4-1 header. As payment I'll fix the cracks in it. Now it's a lot louder and a lot slower. Boo. NA sucks. I honestly have no idea how anyone can stand a non-forced induction miata. Damn. BTW the car needed a decent amount more fuel in the part throttle zones. https://www.miataturbo.net/attachmen...4&d=1191207706 https://www.miataturbo.net/attachmen...5&d=1191207713 |
it looks stealth bomber-ish. Whats that confangled contraption at the tb?
|
Looks like a canooter valve to me. AKA IAC valve.
Cool stuff, n/a sucks though. What sort of FI is in your future? Also, how well did you like welding that cast aluminum to the sheet? |
It's the stock (94) throttle body, just mounted upside-down. Paul also gave me a '99 TB that doesn't have the progressive linkage which will give me more clearance around the headlight motor.
Welding to the intake manifold wasn't as bad as I thought it would be. Welding to the cast waterneck for the coolant reroute was a lot worse (kinda melted like acetone on styrofoam) but fortunately the intake didn't give me as much problems. I welded the inside of the runners and tacked the outside. Then smoothed out/polished the entry to each runner. Next is removing the borrowed header and old Enthuza (again, thanks Paul) cause it sounds horrible and then rigging my 3" exhaust with the OEM header, redoing the coolant reroute in aluminum hard line above the intake runners, oil catch can on the PCV line, overflow tank, 1.8l throttle cable (shorter), and of course the COPs! First on the FI list is getting and installing the larger intercooler and piping. Most likely going to reinstall the TT's, but I may either build a single turbo manifold for the GT2871 (to fit my old 3" single turbo DP) or go with a different TT setup with the 2871 and my 2554. Depends on how long I want to go without boost. |
NA does suck, but great job on the intake manifold. Looks nice.
|
too bad you made that thing to fit the 94 head...
|
i still envy your fuel rail, so simple and effective...
as far as tha mani goes looks beautiful man, can you still reach your oil filter from up top? and will the throttle body being upside down have any affect on the coolant flow? very interesting set up, i like |

I'm surprised you didn't go with a mount for a bigger tb- like a mustang/tbird 5.0 70mm... or have you arranged for that? That's exactly what I need to do. My buddy built a similar approach, though from steel and then used silicone tubes to connect it to the chopped OE mani.

I seriously considered that. I have room for a 65 or 70mm honda TB, but IMHO either are not needed on a turbo'ed car and not worth the $150 or so. But there's room there in case I get convinced otherwise :)
I can always hacksaw the TB flange off and put a mustang one on there too. Damn your friend's manifold looks pretty cool. Good ideas there, I like the runner inlets! EDIT: After further review of his pics, that guy has way too much time...what kind of truck is that? |
i wonder if the new mani futzed with your power curve and dropped your NA power. I can't imagine you spent as much time on a flow bench as mazda ;)
better get that whirlygig back on there. |

Heh, you need to borrow my pup for a "Xander on Manifold" shot :p
|
I figured the big TB would be in line with your lust for lots more power... tho I know it's really not a big deal with even ~300hp.

He has as much time as any of us (young single guys anyway). He just spent it on his truck rather than sleeping... and there's a lot of truth to that. It's a ford courier (b2000 to us in the US). here's his build thread |
yes- it's a "bolt in" for the driveline with the big mazda trans too in the truck.

Hi, I am SOOOOO stoked that you called me young! and also that i'm your buddy :-)
understatement of the year on the sleep deprivation comment, for the last month in nz i was getting less than 5hrs a night everyday. worth it though :-) cheers for the comments. i have no pics of the front in one piece, but this one is pretty much identical to how mine started : http://i50.photobucket.com/albums/f3...ourier1989.jpg http://i50.photobucket.com/albums/f3...rier1989-2.jpg this is mine taken from a video clip a few seconds before locking it up : http://i50.photobucket.com/albums/f323/fredio54/ute.jpg i wish i had a tig to make stuff out of ally like yours :-( one day... fred. |

cheers :-)
beauty was never the aim. something that looks like a ute and drives like a turbo miata was the aim. i'm half way there. (i have the turbo ;-) ) i can weld i promise, most of the project was done looking like this : http://i50.photobucket.com/albums/f3...4/DSC_2274.jpg just got that tonight. i was shocked. taken the night after we got it running. the night we got it running i drove/tuned it alone till 4am. my mate bailed at about 2am :-) it only had one front brake caliper, no rears. was a wee bit scary. got up 8am, worked all day, and thats how i looked about 10pm. ie, not good. the ex mani for example i finished welding at 1:30am. it was all done in a hell of a rush. many many many thanks to Rob. couldnt have done it without his assistance! great guy! but you all know that i'm sure. yeah, the goal is to be able to out track a stock wrx or evo. if i can do that, i've succeeded. holset he351cw similar to hy35 hy9 hx35 good for about 530hp crank. hoping to max it out. in about 2 years i'll be working on it again. till then. it sits waiting. got this pic tonight too, its the only one i have of the whole engine bay as i was driving it : http://i50.photobucket.com/albums/f3...4/DSC_2276.jpg fred. |
god damn! thats a huge ass filter!
|
For such a butt ugly truck that engine bay is beautiful ... i was drooling over that manifold lol

i really like that idea, i may utilize something similar on my mani design, but then again on FI is it needed? deos it help?
