BB turbo’s low pressure car

[ChavyBoy]

Took this out Saturday with Night.Icon...

Wow is all I can say !

It was running just under 200bhp.

It will leave a standard V6 for dead and it has a very smooth torque distribution which is great news for valver owners as the normally asperated valvers suffer from bad low down grunt until about 4 - 4.5k.

The car sounds great when you change up the box (Recirculating bleed valve) with a very quiet hiss and not your RS Turbo hiss that sounds like an air line being diconnected.

1st gear accelartion is fantastic and you dont need to thrash the motor at all to get it going but apply a little throttle and it makes its 17" rubber coated wheels scrabble for traction. Forth gear is like accelarting in third in a modded valver, with plenty of grunt from about 3k onwards.

If anyone is not to sure what route to take with their next engine mod then go down the turbo route as this is such a great mod you wont want to go back to a NA engine again.

This thing can bait scoobies and give then a good run for their money so the high pressure will.... well you can guess...

The guys at BB are very very helpful and certainly know how to make the 16v engine perform at its best top marks.

cb

but 4.5 k for the conversion

i would not expect anything less.

but this is a bolt on conversion aint it. no engine rebuild like nicks

 

[rockport]

if it in included a re-build id be very tempted by this!! £5000 is a lot of money to justify for a turbo bolt on.. not knocking it tho, im sure it is as good as it sounds. £5000 is almost RX7 grounding...

 

[aaronc]

If it was 2-3k i might think about it, but 5k is just way too much.

Bet it goes nicely though.

Chavy;

if its a low compression engine then it would be able to run more boost therefore touching 240BHP which is what Nicks is.

U mean u were out in the high pressure engine (not low comp pistons, etc) dont you?

 

[wongy008]

im sure cb

means low pressure turbo not low compression.

nicks had a full rebuild to handle the high pressure

but the basic conversion does not include this

too much money but if u intend to keep ya clio then why not but het its too much money really

 

[ChavyBoy]

Yerr exactly wongy low pressure as in low pressure turbo, it runs 9psi where as the high pressure runs about 15 psi.

BB will take the engine apart a check all the components to make sure that they are upto the job. They dont scrimp on anything if it needs doing.

5K well spent if you ask me but I am going for the high pressure turbo with low compression pistons.

 

[Tom_16v]

Id love to turbo the clio, I just dont have the money!

Wonder how hard it is to rob a bank.......? lol!

 

[BRUN]

stick a GTT engine in it then for a lot less money

for the same money, a lot more power

 

[wongy008]

brun

old technology and a backward step for a valver mate

i cant see a 1.4 gt 8v pushrod engine pushout out more power that a 1.8 16v doch is the same mods were carried out on both engine

u got more capacity and better breathing on the valver resulting much more power

 

[Nick Read]

GTT a lot less money but like Wongy says its stone age technology. Granted there are a lot of old GTT lumps out there to be had, but running a reliable 200 bhp+ heavily modified GTT 1.4 is not the same as dropping a sh*tty old 15 year old one in straight out of a scrapyard. I might be talking out of my arse, but by the time youd built a 1.4 turbo to run over 200 hp consistently, then got it to fit the engine bay, sorted the wiring etc, surely youd have spent about the same money as a 1.8 16v turbo? And if you want to go more than 200 hp then my 240 bhp is just for starters. If I think I need it later on, the lump will be good for over 300 hp with bigger injectors, a higher pressure map sensor and a more hardcore clutch. Its barely ticking over at 240 hp!

Remember the good old normally aspirated F7P 1.8 16v already makes more power than a standard 1.4 GTT engine and its not turbocharged.

Not that Im knocking the GTT transplant, if I still had my RT Id seriously think about that as the only option if I wanted to run around 150hp, drop in a mildly tuned lump that would make that sort of power reliably all day.

 

[BRUN]

to get the same power out of a GTT, even very reliably, then it would cost 3x less than it would to do the same to a 16v

 

[marcus cliogtt]

I am going for the GTT route for a variety of reasons, the engine may be a push rod but as said before if its good enough for a dodge then its good enough for me!!

To get 200bhp reliably you do need to spend a bit of money but for around 3k you should be hitting that mark, but I believe the most important thing about the conversion is that if something goes wrong with the GTT lump then parts are available of the shelf but if the 16v turbo goes wrong you have to take it back to BB or wherever did the conversion, which will cost you loads of money as they can charge as they please!! Also the valver clutch and box will struggle with 200bhp where as the GTT box will handle this power.

But still fair play if you turbo the 16v unit, just not for me!!

 

[Mikey16vClio]

The GTT box is made for 120BHP and built by Reno aswell so i dont know why you think the GTT box is better than a 16v. My mate with an R5 has a Clio 16v box in his!

Up rated clutches are gonna be needed on any BIG power increases in any car.

 

[marcus cliogtt]

The 16v box isnt a bad box just when you starting hitting power levels of 200bhp then it is doubtful it will last as long as the GTT box, I know a few people who are thinking of using the 16v box with a GTT lump, less gear changes for the 1/4 mile!!

How has your mates handled the power?

 

[ChavyBoy]

Guys the 16v is capable of over 400bhp with bigger injectors and a different map sensor and the same internals put in by BB but its the Drive train that cant handle the power.

Personally I would rather have a 1.8 16v pushing out 250bhp + as you arent even coming close to putting massive load on it were as the 1.4 is under heavy load when pushing that amount of power through it. I mean how many GTT have you seen a year later running 250bhp + that arent smoking like power stations ?

The 1.4 lump is a 8v pushrod engine and a step back in technology the 16v has been proved in the old ice racing series whereby there cars were running over 600bhp out of the same block but through a different transmission. The 1.8 16v has oil sprayers under the pistons which means this engine was initially intended for alot more power than the standard 137bhp.

Dont get me wrong the 1.4 was and still is a good engine and a very cheap one to tune but its old technology now.

I want a car that is quick and reliable and BB build reliable engines and boy there low pressure one is quick so the high pressure one will be an animal.

BTW when running 250bhp you WILL need a williams box as the 16v box wont last that long...

 

[aaronc]

yeah the 16v box dont seem to handle 137bhp let alone turbo power!

Had my gearbox replaced at 60k.

 

[BRUN]

BB also build reliable GTT engines

 

[ChavyBoy]

Yepp they do Brun I agree but if the GTT was so good why bother developing a 1.8 16v turbo, why not just stick a GTT lump in everytime someone wanted to turbo their car ?

Aaron lets face it your car is not running 137bhp is it !!

because people like and buy new things, plus eventually the market for GTT stuff will slow down, so they have gotta develop new things to stay ahead...

 

[Adams_16v]

is it true the phase 1 16v box is better than the phase 2? adis car is running 170bhp+ on the same box it came with i think! and has been for a long time!

 

[Mikey16vClio]

YEAH

In my, my mates whos got a 100k+ box in his 160BHP+ R5 and clean16vs experiance anyway.

BB use a Megane 2lt 16v box on their Clio turbo.

They use a willy box as well..
