With the way I build the manifold I kinda fucked myself on the charge pipes. If I would clock the turbo I would have to cut into the framerail to run the charge pipe and I don't want to do that. And actually the charge pipe under the intercooler has tons of ground clearance, the intercooler just sits real high. I'm getting a tig welder so I'm probably going to modify my end tank for a back door style intercooler to get rid of a ton of chargepipe and simplify a lot of the setup.


As for the nitrous I would only use it for the track. Its too pricy for the streets anyways I still haven't had a chance to run my new setup so I don't know how bad lag is going to be, but if its real bad than I'll probably use the nitrous down low. Right now the nitrous is run off a full throttle switch. I actually have a pressure switch that I was using for alchohol injection but I might switch is for use with the nitrous. The switch:





If the lag isn't that bad I'll probably just use the nitrous as a 1000ft button Also the reason I said spraying under boost is dangerous is cause my buddy has a Ford Taurus with a T04 and a DP 120shot and when we used to spray it the boost went through the roof. Every time we used it we melted pistons. And when I mentioned something to Jeff Evans (BoostedHybrid) he said the nitrous wasn't necessary and a turbo is all you need.

Whitey: Ah well, i guess you have to run the charge pipes like that then... kinda sucks though, but whattya gonna do? lol.

As for that Taurus, the boost would probably syrocket for a couple of reasons... one that is a big turbo.. lol. So, when you hit the motor with nitrous, there is a sudden surge of exhaust energy that will in fact spin the turbo even faster (thats why you can use it to help spool the turbo), so when the extra energy hit the turbo, i'd bet that the WG was probably either too small, or located in the wrong place for it to be able to regulate boost properly. Keep in mind, that many of the big turbo race cars out there use two VERY big wastegates on their cars because they ahve a hard time regulating the speed of the huge turbo's they are running... a TiAL 38mm just simply won't cut it.

When you're melting stuff, it could be a combination of the added boost rising way too quickly, and (i'm ASSuming what equipment it has by the way) the RR-FPR trying to add pressure, which could be pushing the engine beyond where it is healthy, possible causing the EGT's to get too high, and melting... or, it is causing a fuel starvation issue maybe, with the nitrous hitting at the same time as the fuel being needed by the turbo, and maybe your fuel pump just can't keep up... way too many variables to really say what it was, but those are just some thoughts for you

By the way, as for Jeff Evans... he's a smart guy, no doubt about it... but as far as nitrous "not being necessary", thats just an opinion. But when he gets beat by a bottled car, he may change his tune. There are MANY fast cars out there that are HAULING that are running nitrous in their setups... the Titan Supra, Gardella's Civic, the Paradise Racing Corrola (Modified class), etc.. some choose to use it, others dont... i'll be using it

The fuel setup on the Taurus is 50lb/hr injectors, chipped ECU, upgraded MAF with a Walboro pump. If you looked at the pics and saw the regulator, that was for the nitrous (you can see there's no lines going to it cause the nitrous wasn't on in those pics) And also when we ran the nitrous the car was running a T3 turbo off a Grand National which was way too small for the car. Also the wastegate is a Deltagate (which is going in the trash soon) The nitrous isn't being used with this new setup cause the turbo alone is more than the car can handle and we keep blowing 3rd gear. The trans has a quaife it just needs some stronger gears.


The reason we were melting ---- with the nitrous was becuase of the cast pistons. The motor was just pushed too far for it to handle. We have a "wall of shame" with about 10 pistons hanging on it from our car beatings. We can change a piston in around 2 hours we got so good at it. With some forged pistons maybe the nitrous will be back on but the turbo itself is nowhere near max potential.



What wastegate are you running?

ComposiMo

Whitey... information is power... you never said that the car was on a T3 and not a T4, so i was basing my 'guess' on misinformation, so of course i may be wrong... heh.

Anyway, here is the latest update for the car... the back of the fenders finally have 'glass on them, so i decided to do a photoshop of what it should/could/would look like painted, and on the ground... enjoy!

Yeah I know, spraying was on the T3, now its got a T4 Thanks for the input though and your car's going to look kickass when its done.


Don't forget to come back and post more pics when its done

ComposiMo

Oh, don't worry, i'll post up more pics.. heh.

"Come back"? Man, i'll always be around... hell, i've been here longer than you have hahahah!

HMT-Admin

I'll just come out and say it... I'm jealous


I'm taking the "pressure washing" business didnt work out?, heheh.

ComposiMo

LoL... yea, it lasted about 2 months before people started calling me back up again for work to be done, and parts that were needed, so i decided to get back in the game... now its a slightly different story... i still have the PW business, and i may keep it going, i may not. We'll see how this year goes.

Don't be jealous... be happy that this stupid pile of sheetmetal is finally having something done to it... haha! You ought to come to AZ for the first NDRA race... this'll be there, even if it has to have a stock motor in it, it'll be there... haha! Gotta have those 100 extra bonus points for perfect attendance ya know

ComposiMo, that is an amazing car, I'm very impressed by your setup. Can't wait to hear how she runs

Also, (engine-wise) how much will you have into the Tacoma? That sounds like an interesting setup, I've never heard of turbo Tacoma's.

ComposiMo

Sinister: Thanks mang! I can't wait to hear how she runs either hehe. As for the Tacoma, engine wise i'll have done: Rods, Pistons, Valvetrain, and port work... basically it'll cost the same as any other motor build, except i won't have to resleeve it, so i'll save about a grand there. Realistically though, you only have to do rods and pistons, and it is recommended to at least do the 1mm oversized valves... otherwise, the engine is good to go. So, at a minimum, you have:

Used Short Block $200
Chromoly Race Rods $600
Racing Pistons $550
Oversized Valves $250~
Assembly (If you can't do it) $350~ (depending on your connections hehe)

Total $1750.00

Just add boooooost

As far as engine management, you can do what i am doing, and try to adapt an AEM EMS to work, or you can go with a fuel controller, and an MSD BTM for spark.
