Silly question

I know this sounds stupid but can you run a turbo and throttle body's?

Aye throttle bodies open to the inside of the engine bay? I don't know much about throttle bodies but if they are just open for each cylinder it's a no

28th April 2014, 19:25

Ahhhh okay so it's one or the other

28th April 2014, 20:18

Turbo compresses air and if throttle bodies take it from the engine bay, you can't compress it and release it back into the engine for the throttle bodies

28th April 2014, 20:23

Yes, you can run a turbo and throttle bodies.

All a throttle body is, is a single throttle body per cylinder. You can still have a plenum on the throttle bodies instead of just a filter to air, and then feed compressed air from a turbo / charger feed into the plenum as you would normally.

The gains aren't really worth it for the cost on builds ordinarily though, as really throttle bodies give sharp throttle response on NA engines which will be negated on a boost build anyway.

That's my rough understanding of it.

28th April 2014, 21:13

As above, yes you can

Can anyone remember that track vts that was on bodies and turbo? I'm sure it was barn works motorsport or similar? Trying to find find the thread for someone but to no avail...

28th April 2014, 21:22

Told you I had limited knowledge, just a guess from me!

29th April 2014, 00:43

So what would be better to do?

29th April 2014, 02:26

Wake up from dreaming

29th April 2014, 08:52

there will be zero gains from fitting t/bodies =tirbo over single t/b =turbo

unless it is making its power at over 9k--which it won,t be
so save your money

Thinking about it, you wont get any gain on the sizing intakes of the itbs and when you attach a plenum to it, its gotta go through a single throttle body size hole and through boost pipes of "x" given size so i cant see the attraction only that better flow across all 4 cylinders....

Nope not even that, just change the shape of the intake runners on a normal plenum to achieve that...

So throttle body's or a turbo in your guys opinion as I don't know what road to go down?

Then with the best intentions, I'd really go and read up and decide what you're after and why.

Either represent a sizeable investment, and it doesn't sound as if you'll seriously end up doing it if you don't even really know what you're after at the outset.

What will you use the car for, what support mods will you make, apart from the huge difference which is the general character of the engine. A revvy NA screamer lump is a very different animal from a boosted lump.

I'm not trying to be harsh, but it doesn't sound like you really have an idea of what you want, or what it will cost. I wouldn't be attempting to turbo my car because some people on the internet told me it was better than bodies, or vice versa.

29th April 2014, 11:07

Like I have read up on it like body's give instant power as turbos have to spool up I want to break the 200bhp mark so I was thinking turbo and I'm spending about 8k on the engine

29th April 2014, 11:15

Turbo to break the 200 mark will be piss easy, n/a will cost pretty much the full 8k... For 200bhp you really need a chassis that can take it, boost it, itll be better to drive normally day to day (before anyone jumps in, yes there are a few drivable 200bhp n/a's out there) cheaper todo and spend the money else where... Like a track day...

That's not really reading up on it though is it, that's basic knowledge.

At 200bhp you're going to start chugging through gearboxes fast unless you're doing a BE conversion, so you may want to budget for that.

Sandy Brown built a 220bhp N/A engine for JPSaxo's car on here, but I don't think you'd get far with 8k.

Then there's suspension, brakes, clutch, what sort of management will you running, who will map it, what about turbo oil feed's and drains, exhaust will need to be fabricated, etc etc.

It's not a cheap thing to do, it can be cheaper if you know what you're doing.

I have heard something like camms can't be run with boost is this true?

No?

To get the best out of your car you want a cam profile that's matched to a turbo / charged application rather than an N/A setup.

I don't know enough about turbo builds to put my own setup together dude, I'd be doing way more research into it first. I think that's where you need to start.

29th April 2014, 11:31

I think its best if you go and do your research, look at jpsaxo's thread look at blackie2k12's thread look at sexygt's thread, look at ross's thread, all are over 200bhp and see what you can realistically afford... I dont know what my car has cost, its over 8k now, its about 170ish n/a and i did everything myself, but its a class winning car and power isnt everything....

29th April 2014, 11:50

29th April 2014, 12:21

I just want the car to be as fast or if not faster than 1.8 turbos and stuff in that class like Leon's ect

29th April 2014, 12:30

Why don't you buy something decent to begin with ? Could buy loads with 8k

29th April 2014, 12:36

I think unfortunately you're sounding more and more like you fall into the category of 'dreamer'

I read that the 1.8 20VT engine slots straight into a saxo?? Plug and play pretty much

29th April 2014, 12:48

8K on turbo'ing a Saxo ... fuck that.

Just buy something more powerfuller/reliabler/prettyer/betterer.

If it is turbo'ing the Saxo you have your heart set on then Ross on here has a 400BHP 106 GTI. Pretty sure he could point you in the right direction.

Don't listen to D4MJT, he's just giving advice that he gets from Yahoo Answers, he has had his male status questioned and as a result wears overalls all the time and waves around a greasy spanner in hope of some form of redemption.

No match for B8's and a lower strut brace I'm afraid.

29th April 2014, 12:54

There's no point being bitter about it Bret, I just don't find you attractive, get over it x

Of course! Silly me, but don't forget dem camz!

29th April 2014, 13:01

I'm not doing it purely on speed, I want a sleeper car that's why I chose a Saxo

29th April 2014, 13:04

Surely you'd want something larger if you wanted to sleep in it?

That's a blatant lie.
