Throttle body set up.

5th February 2010, 18:57

right, just need to finalize the last few bits and pieces i may be forgetting.

I am getting/got the following parts for the set up.
Depending on the best quote i am either going to go for the two most trusted and well known companies, ATspeed and Northampton motor-sport

Jenvey Bodys
PH3 cams with followers - Got
Omex ECU - In Group buy
Cat cam vernier pulleys

I have spoken to Troy from Northampton motor-sport about a quote on fitting the above parts and asked him what other bits i need, he suggested, maybe upgrading injectors to either pico 270cc, or 330cc.

A fuel pressure regulator? Doesn't the car already have one of these? Or do i need an aftermarket one?

And he also recommended replacing the Cam belt which is a standard thing to do really.

Anything i have missed out on?

Cheers guys!

you will need a fuel pressure regulator as you cant use the standard fuel rail with bodies.

Trumpets and a sausage filter?

Aha! You have/had a bodied sax if i remember correclty! Any idea where i can get hold of one from? Or is it best to leave it up to the tech guys to get one?

Trumpets will come with the Jenvey kit!

Sausage filter will be added to the list

Filters are for women

I just used a fse powerboost valve on mine.got it from some one on here.then i bought a pressure gauge and set it to 3bar.then had it mapped to it.

they maybe arent the best to use as they can be quite hard to map to. you can get the regulators from most places even ebay.

O right nice one thanks!

I will probably leave that to one of the tech guys to source and fit for me then..

What sort of bhp did you get out of your Sax?

Yours was on Jenvey bodies as well iirc?

I strongly recommend using original type fuel regs, adjustable aftermarket ones often cause problems down the road I find.

Really? What sort of problems?

I'm using a weber alpha external housing with the standard 3Bar FPR - seems to work fine

Hmmmm, yeh, i most defiantly will probably just leave that part for the tech guys then.

The next 5 months are going to be very fun and expensive!

lol, definitely expensive!!

Could run the FPR housing from the standard vtr in the back, and use some oem connectors with some fuel hose - would be cheap but work perfectly fine.

I paid around £70 for mine and was silly to tbh - should have gone with the above setup for sub £10.

asw - it's the red thing just next to my bodies

I never knew the power of mine.when it was mapped it made 157 iirc. the guy who mapped it couldnt understand why the power was so low.he thought maybe the cam timing was out.It turns out that one of the spark plugs was loose so the compression was leaking right out of one of the cylinders and making a popping sound.

once it was sorted I never had it rr'd again. it absolutely flew though. i miss it like mad.

5th February 2010, 20:02

dont expect huge power with bodies will be round 160 unless you go with head work and pistons to see bigger power

5th February 2010, 20:03

We use Turbosmart fuel pressure regulator's. Very high quality products. But not cheap.

er yes you can, both of my TBd engines ive had ran the stock fuel rail

it depends on the bodies you are using, its not a case of all wont allow it.

you could use a different type of t/body setup which can use standard fuel reg .
you can also have an itg type air filter (foamtypoe + back plate ) ready drilled

Don't really need uprated injectors unless you've got a wilder cam, and then I'd go for clio 182 injectors..

Fuel pressure variations that throw the map out, continuous and transient. Very frustrating.

Seems like a wild guess dont you think.

6th February 2010, 21:10

Suppliers will often tell you whatever size they have in stock is perfect for your needs, but well matched injectors always map better in my experience, so it's better to get them right if you can. As a rough guide for four cylinder naturally aspirated engines on normal pump petrol, to get the minimum size:

Divide expected bhp by eight and then multiply by eleven for cc/min per cylinder.

For example, expecting around 160bhp.... 160/8= 40, 40x11=220, so around 220cc/min.

For boosted engines it's more like divide by seven, times by eleven.

Sorry i missed this post sandy! That very helpful, thanks for that!

May be getting some headwork done by you! Just trying to source an engine in its own for a rebuild as i need my car daily!

definitely run a filter. As long as its not the crap socks then airflow and pulse tuning is virtually unaffected. A sausage filter is best as the air round the trumpet bell mouth is unaffected by the filter itself.

like we use on the ATP bodies

why would this be i use a adjustable fuel pressure regulator never had any problems

Glad to hear that, but I have had problems on several applications and it's not just me. Whether it's age, heat or quality related, maybe a combination of all three. The consistency of the Weber+Bosch fixed regs has been far better in my experience and ditching adjustable regs from my customer's cars has proven to be a good move for reliability.

listen to sandy -- he is correct --you always use as many OE parts as possible
