* Based on 2 previous cars (EK K20 & DC5 K24) tuned with AEM then swapped to Hondata & tuned again.
Adrian is that power output typical for a jdm k20a with all the basic bolt-ons with cams? Did you choose/suggest this combo?
The combination used for this car is all Nicks. Nick built it himself & has proved more than capable with the spanners.Quote:

The main power advantages for K-swaps like this over & above the bolt-on parts & cams used are no power steering & no A/C.
(That’s power to the wheels)
Disadvantages include noise & comfort.
Adrian whats your thoughts on the electric power steering pump from the mr2 for the kswapped cars?.
8hp vs 1-2 hp loss
what do you mean 8hp vs 1-2 hp loss?Quote:

Low in power numbers but a great fun car to drive none the less.

Well Claimed Hp Loss when using P/S is around 6-8hp
I've actually tested it on a B-Series track engine & the loss was 5.7kw.Quote:

So that equates to 7.6hp at the wheels...
But it's only right up in the top end, the rest of the rev range is even stevens
NB:This is using an underdrive system vs none but I don't have any info re vs std pulley sizes but it's likley to be a little more.
The electric pump sounds like a good idea though as K's see measurable gains for using such systems (EP3, FN2, CL7)

The above sheet illistrates the power loss from no power steering to using an under drive OEM power steering system. The main loss is up high.
hahahahahaha definitely noiseQuote:

As requested, Nick's (evil R34) before & after dyno sheet.
Please see post # 527 for specs.
evil R34 can elaborate on the changes.

Notes:
* Above graph shows before & after power output (Base is stock - no modifications)
* The head has recived extensive port work based on our latest race engine data.
* There are a few pit falls in using this combination without certain proccesses being performed.
* The midrange could be improved significantly with the use of a better header (Ie Toda)
* Alternative camshafts may also deliver better results (I'll know soon enough anyway)
Impressive all things considered on the above post.....
So a cam change is going to happen?
