What power can be achieved without boost or throttle bodies - 172/182
assuming you're including engine internals in the allowed list, about 210-215bhp with high compression pistons, wild cams, headwork, and quite heavily reworked inlet manifold (and some extra parts for strength and reliability) You'll be needing aftermarket management at this level too or it will drive like a dog.
If you're meaning mods to a stock engine, cams, breathing mods (exhaust and proper air filter setup) matched inlets and a good map can see 190-195

No, im saying that they work very well with the RS2, if you ran aftermarket cams with an RS2 you could get more again, but would need to be on aftermarket and it wouldnt be as nice power delivery.
IME the Rs2 and 197 cams is the best combination for a daily clio based on how I like them to drive, its not the only option though, just one I personally like.
No, you get utterly no kick at all, its just a completely smooth delivery really.
In fact on Mike's IIRC there was no more than about 3lbft of variation anywhere between 3k and nearly 8k
If you like the "feels a bit flat, bang big kick, goes ok briefly, nothing again" of the standard engine you would hate it as its the total opposite.
I guess if you really want the kick (which is mainly caused by the utter lack of it doing anything below there) you could get a car with a normally decent power delivery like an RS2 one mapped particuarly badly under 5k to replicate it and then still gain the benefits at the top end of the rev range?
Or you could just drive at half throttle till 5K then floor it if you really dont want any torque under that?
Yeah 421s are still quite a peaky delivery like the standard ones if ran on the standard inlet.

A replacement inlet manifold designed to work with the standard Ecu and just a remap rather than needing aftermarket management like bodies do.
Expensive but simple bolt on mod that is easily reversible.

You will not miss that kick. I went out with Tom (of JMS) with the first RS2 and the power delivery was brilliant, constant torque just pulls and pulls to the redline. He really did design a bit of brilliance there. And Nick had great results even before mapping.
I never drove it but given my 330 has almost exactly the same shape graph on the rolling road, I can imagine the improvements to driving over a standard 1*2 would have been huge.

Without bodies like this thread is asking?
Eh? Standard car is injection and single body as opposed to bodies. Rs2 retains that (and cruise control etc)
WRX
Never mind:banghead:
How expensive?
I've done a couple where the port shape and size has been completely changed in both the head and inlet manifold. It's the level of work I would only really do for a high compression build though. A little bit over the top for a stock bottom end. Mostly my heads are worked to include an enlarged exhuast port (ph1 style) and a tidying of the inlet, then matched to the inlet to be used (be that ITBs or reworked stock manifold)

Dan, when reworking the standard inlet manifold are you able to rework it fully to be optimum? Or is there a compromise so to speak due to the construction of the upper half?
Here is -J- graph before and after RS2. You can see the "5K kick" (which would be better named a "sub 5k hole" really)You could easily map it to still be equally gash under 5K if you wanted though, and then just have the gains at the top end.
Like the look of this graph, I like it smooth as opposed to laaaag and woahhh
Tell me more? Might treat the van unless as I suspect its gonna cost a fortune..
Hhhhmmm I wonder!!!!
