My journey into the unknown in a quest for lots of torques (whatever they are) begins. Given the long-stroke nature of the 2.2 Z22se I've eschewed sky high revs, hot cams and throttle bodies in favour of the blower route. Booked in with Courtenay next week. However, instead of their normal route of fitting the standard vx throttle body I've made up a loom extension (with the wires changed over) and supplied them with a 68mm TB (which is what is supposed to go on the s/c and fits without an adaptor). Apparently they've not used one before with the blower conversion so It'll be interesting to see the results -- hopefully more torks piled on to lots of torks. Rods have been changed for beautifully-made Eagle items (very cheap from the US now with the two dollar pound) and, in the final quest for a further torks, a Tsudo (formerly Weapon R) 4-2-1 manifold. the latter required major surgery by Mr Mig Welder to the downpipe section. In the pix I'm indicating a joint which was badly warped and had to be machined/pressed flat to get a gastight joint on my Tsudo. Hope to be posting the results of all this in a few weeks when I've got the clam back on.

Sorry. The system does not seem to want me to add even the smallest jpeg so looks like you'll have to do without the pix.

You'll have to host them on a hosting site, e.g. photobucket.com

I'm really looking forward to the outcome here, hope it works out great. Especially since I'm next

[Robski]

It will be very interesting to see how the graphs differ from the 'standard' s/c installation. I presume you are going straight for the stage 2 level of tune? Is this going to be the basis of the stage 3 level of tune mentioned elsewhere on this site or is this your personal home brew recepie? It does all sound rather interesting though Rob

[slindborg]

supplier for the rods?.......

I can host some pics for you if you wish. Email me @ charles_lovell@hotmail.com

Sweet!

Two questions:

Are you going to run the SC with standard cams?

Is the boost level fixed on that supercharger Courtenay use?

Ok, I have tried to host the pix on photobucket. Not too sure how it all works but these might be the links: <center> <a href="http://i117.photobuc...tsystem003.jpg" target="_blank"> <img src="http://i117.photobuc...em003.jpg"></a> <a href="http://i117.photobuc...tsystem002.jpg" target="_blank"> <img src="http://i117.photobuc...em002.jpg"></a> <a href="http://i117.photobuc...tsystem001.jpg" target="_blank"> <img src="http://i117.photobuc...em001.jpg"></a> As for the other questions: standard cams, Courtenay effectively increase the boost level by fitting a smaller pulley to the blower, there are several U.S. suppliers of Eagle rods if u do a search on e-bay. I think mine came from JBody performace Co Ltd. Rob its a bit of a home brew recipe and the boys at Courtenay have mentioned they are not sure the blower will work well with the Tsudo manifold -- we'll have to see.

Think I deserve a passenger ride for this Looks fantastic...

Did Courtney recommend the Eagle rods, just thinking if I should get some ordered now

[slindborg]

i did aspot of googling in the US last night and found one company that was selling rods for $299... thats jsut bonkers cheap!!!!! what are the rod part numbers so that i/we can get the right ones? Maybe a little "group buy" is in order to save on shipping costs etc.

GM recommend eagle rods, they're good for 600bhp!

Very nice looking! Did you get away with not cutting the boot? Which part is fabbed by you?

Cheers, Paul.

Chaz - Thanks very much for putting the pix on. You are a prince among men. As for the rods, I cant seem to find the documentation right now so dont have a part number as such but as long as you get the Eagle items for the 2.2 litre Ecotec engine they are a direct exchange for the standard rods and there should be no possibility of error. They come complete with ARP rod bolts, torquing data and the correct thread lubricant. I used the OE pistons on them (in the same bores) and refitted the bearing shells since my engine had only done about 12k and the shells were perfect. You can get lower compression (8.9 cr) pistons from the States for about $500 (£250). Courtenay do not recommend changing the rods for their conversion since the standard ones are deemed to be adequate but I just feel better about fitting the Eagles and at current prices it seemed silly not to.

"Which part is fabbed by you?" Paul, There is not need to make any changes the manifold itself, which comes beautifully TIG welded and should really be hung on the wall as a work of art. However, the downpipe (two into one section) does require major restructing for our application. You can see from the crappy MIG welding that I did that bit. It takes a long time, a lot of swearing/cups of tea and you need a powerful welder. My recommendation would be to farm it out to a professional TIG welder then it would look as good as the manifold. Since Courtenay have some doubts about its suitability with the blower, it would be better for anyone considering the blower option not to order a Tsudo manifold until we see how it works on my car.

Yeah, i remember them saying they lost power with the regal manifold, but i can't help thinking it has to come down to the mapping... More flow has got to equal more power?

[MAP18W]

There is no need for steel rods on the Stage 2 conversion due to where we set the rev limit (if there was a requirement for them we'd spec them into the conversion). We do not over rev the engine to get the bhp from the Stage 2 therefore the standard rods are more than capable, as they are operating well within their capabilities.

[slindborg]

theres that high horsey again lol if you read the thread it states that he knows you dont spec them for your "modifications" but he fitted them because he wanted to....... if its above spec then surely there are no grounds to whinge

That wasn't a whinge..... or a high horse That was merely re-itterating a fact... just wanted to clarify the standard rods are more than adequate/capable rather than the stated

deemed to be adequate

Didn't want anyone to think we'd leave in weak components! Sometimes things get misunderstood on a forum...... I now appologise if that was the case.

[NickB787]

Here I was thinking more money to be spent So with standard rods ect and with not changing the rev limit, any idea what you could get out of this engine and still have an everyday RELIABLE car
