Which is the best engine to go with ITB?

that was my plan, 9a crank and pistons into an ADR, and chop the plenam manifold up with the throttle bodies up by the bulkhead. never happened due to real life getting in the way

 

there's a manifold like that with bike TBs on ebay presently - is it yours?

 

nope, never got that far, do you have a link?

still got the gixxer bodier here under the desk though

 

You do not need to fabricate anything to fit the GSXR ITBs onto an ADR.
Look back at my earlier pics in this thread. 9 x 8mm spacers for the ITBs to be spaced to 88mm bore centres then they fit straight onto the ADR inlet manifold.
If anybody is seriously interested in this set up give me a pm.

 

Aye, Barny had that setup on his at one time.i do seem to keep repeating myself in this thread.

I was going for the long inlet manifold just as an experiment, but we weren't sure what we could get away with compression wise so 9a crank or diesel, didn't get to the dry build stage



I gave up originally due to the cost of the ECU and mapping and just went and bought a complete car with 250bhp

 

If you have a look at coupechamps "now you see it thread", his 20v NA engine seemed to produce good results on a turbo short runner single plenum inlet manifold.
Until it let go that is.

 

do you have a link Danster, can't find a thread with that title or similar

ta muchly

 

Which is the one Adrian/20vkid has in this black Mk1? Is this motor some rarity? I know it's alloy blocked.



AFAIK he 'just' bolted it in, stuck on the TBs and added cams & 4-branch - but maybe that's a simpilification! 190+ bhp IIRC poss more. Brooky? Certainly a rockin' track day toy, makes a great noise and and I know he's had loads of fun with it.

 

That is using a 20v to weber sidedraught carb style inlet manifold similar to the one below. It may have just had flanges welded onto the ADR inlet stubs though.
Those are TBs that use the weber style flange (lumenition perhaps?)
Alloy block could be AKL but that would need a crank change to 1.8. Being 06A they are long nose cranks for the oilpump chain drive.
Cam cover look odd to me though.

 

I've got it in a mag article - will check later.

 

Your Jetta was one of the lowest with 22bhp seen? Are you telling me it was 22bhp lower on k-jet? A well set up k-jet engine with your spec would have closed the gap a lot more than that. Were these people standing at a bar with ten Stellas inside them when they quoted the figures to you?

 

is the alloy blocked 20v a real ALT? only available in a few passats i think

 

I do not know much about the ALT.
Boff and Mad 20v have been back on here lately, so may shed a little light on that. Toyotec may be aware of the engines also.

I know the AKL is a short alloy block 06B type block. 1.6 8v crossflow.
I think there is / are tall 06* blocks though. Some maybe alloy. I thought some folks used the diesel block too IIRC.
I also remember seeing a Seat Toledo on a mates MOT ramp one day, and I it was a NA 20v in it with an alloy block similar to my own AKL one. Presumably a 1.8 or 2.0? That is why it caught my eye. The alloy blocks have lots of ribs all over the block and make it very different in appearance to the iron ones.

 

188bhp it is, standard 20v nasp with a set of cams , tb's and Haltech ECU i think Benny will know better than me

 

Will pass the thread on to Paul, i know he bought an alloy block but when it was looked into it was going to be more hassle than it was worth.

All these engine codes are a bit foreign to me now

 

Seem to have filed it.. it was PVW IIRC a couple of years ago. Anyone?

 

ive got it just need to dig it out

 

yes that is Exactly what I am saying. Same dyno same day.. I swapped all the k-jet off it and fitted the bodies and connected up the dta in the carpark..

when mapped it made 22bhp more than on kjet but instant throttle response and wider torque spread.

the figures are as reported internationally.. I have no reason to doubt them.. and many of the customers are Racers, who have engines worthy of running 45mm bodies or more.. HENCE why I do not, and have never said what they will give. BECAUSE the outcome is entirely down to the spec of the motor to begin with. bodies simply facilitate more power IF the engine wants to give it. simples
