[All] [Generic] Throttle Bodies ...

Post by Bender Unit »

Does anyone know of any throttle bodies suppliers. With the excpetion of DTA / Jenvey.

Just investigating throttle body suppliers, before I decide to go for 20v 4age throttle bodies.

If anyone can help that would be cool. They can be anywhere in the world - not fussed.

Cheers

James,

Andi Martin has just done a TB conversion to his Corolla. He used GSX-R 1000 TB's. Might be worth giving him a bell mate... :thumleft:

Is Andi Martin on here? I have been looking at using the GSXR TB’s – but I haven’t had much luck in finding a set.

Also keen to see if I can find an off the shelf bare bones ITB (no manifold so I can cover all bases)



Tried looking at the link Chris, doesn’t display – think it must be the work firewall. Will have a look when I get home.

Sending you a PM in a mo. ;)

The link does take bloody ages to load up James, or at least does on this computer. ](*,)

I used a pair of 'dead' Webber Dcoe 40's with a web con TPS and velocity stacks.

Got 204hp out the 4ag so must have been working well :thumleft:

Zoiks! Why did I know they wouldn’t be cheap. Flaps!

Unless I use old bike carbs then its unlikely I will be able to get anything super cheap. Some Klein’s Slide Carbs would be nice – seeing as the fuel rail and injectors are mounted to the head then I am sure they can be hooked up easily, with a little manifold. Annoyingly Klein’s also seem to command a premium! Champagne taste and beer money!

As I am a spazz, can anyone tell me what sort of bore I should look at bike carb wise (38mm?) There seems to be a massive variation in what’s available. Will want them to run on a 1.6 L up to 200bhp or more? What do the big bikes (1100 – 1300’s run in terms of bike carb size)

I have also considered about this, would mean I would be able to keep the engine bay looking old skool and carbded but with EFI on the fueling. I would need to find some old carbs though, rather than use my Mikuni’s as they would fetch a good amount when sold on. Also the Carb manifold is for a big port – and I am going for a small port head.

How did you rig the TPS up out of interest, got a few ideas but its interesting to see how other tackled it?

My Raw engineering manifold was for small port as i too had a small port head.

As for TPS - check out webcon website - its all there.

I got a set of TB's off a gsxr750 for my brother, they are 42mm tapered bodies.

Got them on ebay for about £80, i think but aint 100% they take the small pico injectors, not small but compact is more the right word.

This is for a 2.0ltr 4pot ford engine, not sure weather they would be suitable for yours but if 42mm are a good size for your application then its another option. If you want any pics or out give me a shout and i will post um up.

For bike carbs, when i had my ford, at one show a guy had an RS1600i on R6 carbs thats obviously a 1600cc but only 8v, so again not sure if they would do.

Regards, Chris.

I started with 40mm bodies but after making up many inserts we found 38mm to be best for mid range torque and not having to rev it as much.

This was with a heavily ported head + TRD BD3 cams

Trawled the site but couldn’t find anything, it’s a pretty crap site. I will try and mock something up which utilises the stock TPS (if its possible and provides the right readings for the ECU).

I got a set of TB's off a gsxr750 for my brother, they are 42mm tapered bodies.


I have looked at the GSXR TB’s and the sizes seem to vary quite a bit, but they also come in cheaply so I will get a set for test purposes. I have noticed that they fit Mikuni Slide carbs so I will roll with a set of those and see how I go. Strangely they seem to have a slide and a conventional butterfly in the carb.

Got them on ebay for about £80, i think but aint 100% they take the small pico injectors, not small but compact is more the right word.


I will utilise the injectors in the head rather than the TB injectors, I will just block the old holes up with JB weld.

Think I will just get a set and have a mess around and see how far I get. For the proper kit I want Keihin FCR slide carbs as they look ace, come in big sizes and also angle up from the head so I can clear the brake servo which is a problem on AE86 carb / ITB set ups. Problem is Keihin’s are pricey!

I started with 40mm bodies but after making up many inserts we found 38mm to be best for mid range torque and not having to rev it as much.


Thanks for that Nathan. I am going to try and get some 36 / 38mm GSXR carbs and go from there. It’s just a project for the time being, so no real fuss if they aren’t optimum performance. I am hoping that the final product will use the Keihin’s and be fitted to a small port, running 310/304 cams though. That is unless I can source some cheap 20v TB’s which is proving difficult at the moment.

IIRC GSXR 600s are (on the whole) 36mm. Be careful as some of the variants are not respacable so may not line up with the ports 100%.

AFAIK the 600 TBs have been used to good effect on the 4AGE. Will have a look for the article. :-k

Edit: Not the article but useful stuff: http://www.msefi.com/viewtopic.php?t=6627 How wrong was I. :oops:

running 310/304 cams though


Crikey, my BD3 profile was 290deg and i had nothing below 4k. 310's will be pretty peakey.

Best get that nitrous on order to pick its feat up low down! And you want a static CR of 11.5-1 MINIMUM!!!!!

N.B - dont even consider trying to run the cams then do the ITB's after as its totally undrivable on the std plenum and idle is non existant.

The ITB's should idle OK with these cams but the mapping has to be bob on to combat the terrible 'jerk' before it comes on cam. The eManage i used was no where near good enough. Even a PFC would be way out of its league at this state of tune.
