I've been wanting to add power to my car for a while, and haven't been able to decide what route to go. As I've posted in the past, I would love to do an all motor setup with spray, but the more I look into it, the more expensive it becomes to do correctly. I've kind of given up on the idea of going all out and would like to get the car around 250-275hp to the wheels. I can do this one of three ways:

PnP my head, tune, and a 75 shot

Stage 1 turbo kit

Supercharger w/ slight modification and tuning

I don't really want to get the s/c but not limiting my options. I've been looking into making a custom turbo kit with all toyota parts and should be able to put one together that should get me close to 15lbs of boost for around 1500.00. I'm thinking that doing nitrous correctly is going to cost me a little more then that considering the additional head work.

Opinions?

Wow its possible to get a turbo for $1500? I always thought they were at least $2500-$3000. Ya if I were you I would go with the turbo! Thats what I want sooooo bad! Just my preferance.

The turbo kit that I'm considering building is made with all stock toyota parts and most of them would be used. The most expensive part of the kit would be having the exhaust manifold made and the down pipe. To do it with new parts it would cost substantially more.

As much as I want to do all motor, I just keep leaning more towards turbo. It'll just be so much cheaper. I just put a bid in for the turbos I want, and we'll see what happens. And yes, I said turbos... :twisted:

Wait... Turbos? Now you're talking! Can you imagine that? TT tC? Sexy.

But in general for hp adding, I personally would like to go with the s/c. Easy maintenance, and moddest gain. But it would be really expensive getting it up to 250-275 hp for your goal wouldn't it?

Go with turbo. Sorry, turbos.

Nah man, not if he goes sequencial turbos. Virtually no lag there.

In regards to turbo lag, it really doesn't make a difference. I do not own a tC, but I own a turbo car where the turbo begins to spool at 5,000rpms. Now people would imagine that this is way to much turbo lag, but if you down shift you would never know. At least for my car / setup once I go into boost, I stay in it after every shift.

It just depends on how you want your car to react. A smaller turbo would result in faster spooling thus less turbo lag but less over all power. yada yada yada, this can go on for a long time in regards to setups.

As for the OP. If you can source turbo parts for $1,500<=>$2,000 with everything you need excluding tune. Do it up, you'll love your car so much more afterwards.

We'll see what happens, but I just bought a set of sequential turbos and an intercooler. I'll have to get all custom piping made and I already have an emanage ultimate. Can anyone recommend someone that can make a custom exhaust manifold?

Nitrous FTW! It's there only when you need it! Turbo kits can really lower the life of the car too. Nitrous does too but if used right and installed right not as much as a turbo.

Interesting idea on the twins....how do you intend to get the manifold done? 2 x 2? I assume you'd have to get small turbos to get them to spool right? Also, who is making that manifold for you? I had been calling around to see if I could get a custom manifold made, and some of the quotes I got were just a few hundred dollars less than the turbo kit I have already Granted I've been calling shops who build actual race cars, but I figure if I do it,I'd go balls to the wall and do it right

I bought a set of stock turbos from a supra tt I plan on doing a 2-2 setup on the manifold, and my buddy knows a guy that can make them but said it'll be around 600-800 for jethot coated stainless

I'm shopping around a little to see if there are any other options. If worse comes to worse, I'll make one myself... now where did i put that duct tape...

That is an EXCELLENT price for a custom manifold!!! Just make sure they use the highest rated steel to avoid cracks. I think the lowest price I got quoted for was $1875

This is friend pricing, but I had no idea it was discounted that much.

Yeah yer getting a sweet deal! In fact, if they are doing bench flow testing on it too, you are golden and should jump on that!!!

don't know if he has flow bench capabilities or not. I was looking into trying to get one of those cuz I had no idea how much they cost, and now that i know i understand why some custom piping is so friggin exspensive!

As ideal as it would be to get that done for the exhaust, its going to make a world of difference on the intake side. The exhaust doesn't have to be perfect since its being forced out. Flow benching the exhaust could potentially give a couple extra hp, but on a boosted application it won't make a noticeable difference.

Don't most people/shops do airflow bench testing on manifolds anyway? I thought thats how they knew the manifold worked, haha.

I agree to an extent, but bear in mind that a turbo application is driven by the exhaust gases. Without a proper flow, your exhaust pulse could get wonky so either the compressor wheel doesn't get enough force to drive it properly, or the pulses could be in such a frequency so as to actually slow down the wheel. Either scenario will give you results far below the potential. Add in the fact that you are trying to do a twin application, and you have even more factors regarding exhaust pulse.


Speaking of this....what is our cylinder sequence (facing the engine left to right 1-4)? Is it 1-3-2-4?

I'm with you on the pulsing getting out of whack. This guy does exhaust manifolds among other things for a living, so I'm assuming he does flow bench them, but I can't say for sure. I guess I'll find out soon enough

I'm pretty sure the firing order is 1-2-3-4, but I can't say this for sure. I remember reading it somewhere but I'll have to research it...

Anyone know about the individual hp ratings for our stock internals? Pistons, rods, bearings... I think all of them should be able to hold at least 300hp, and I don't want to go quite that high.
