With the sr20ve, i wouldn't worry to much about the solenoid, it would be easy enough to knock up a small box (similar to what mini's do when running side draughts)to clear the solenoid, assuming firwall mods are allowed, if not they don't stick out a terrible amount so probably wouldn't be to bad. the biggest issue i think would be a suitable gearbox with custom housing, could be expensive. I also got the redline wrong sr20ve redline at 7800 or 7600 not 8200 like the sr16ve but they will still happily rev to 8 with stock valve gear. For more info on sr20ve chesk out www.sr20forum.com they have a whole section on sr20ve as well as hot na sr20 builds. worth a look

Cheers
Nick

Craig,

Found a set of injection perfection throttle bodies on a manifold to suit SR20DE for sale. Slightly used, $900, well below the $2700 buy price.

hey craig found the perfect already built engine for you Tomei SR20
Can take note of the specs its running they are making 265PS @ 7500 and 27kgm at 5500 Shame about the price tag around $17k then you got clutch and pressure plate to worrie about. So say a nice round $20k LOL
I also notice with the 180PS version they run Sr16VE pistons to bring the compresion up
I recon quad throtle bodies cams and a bit of head work should see at least 200 crank hp Good luck with it. $5k budget is for engine build only?/ or injection ect as well??
Cheers Andrew

Go the S15 SR20DE VVT (Japanese lowspec 200sx).

Easy obtainable for under $1200,

96kW at the wheels.

I don't know if you should be so quick to rule out turbos. Spending the sort of money we are talking here on a turbo CA or SR will probably get you as close to the front of the overs as 170rwbhp will to the unders in NSW. And with all that torque and low revving because of the restrictor, you won't need the expensive of a close ratio box. Bang for bucks, the turbo options wins hands down.

Why not use the quad throttle body setup from the Pulsar GTiR, some cam and head work, that should get you up there shouldn't it? run a wolf or similar. should be able to get it under the $5000... maybe or am i talking out of my A$$?

The VE is an interesting animal as I could keep it factory and have great HP.
I can get a VE with ECU and loom for $2000.
Now I believe there are some who have put a VE head on a std block and had the oil tube draining back into the sump and have taken the dizzy out and replaced it with quad coils out of a Hyundai. Also I was wondering how you could change the solenoid for the cams...would anyone know how to change this over.
If I had the quads chipped ECU and VVT then I should be able to get 210 hp which isnt bad at all...

if i was in the same situation in you i would be considering the following options.
1: as you said above cams, quads compression etc. lots of money but lots of fun. But how reliable?
or
2.the sr20ve

I would investigate the sr20ve more. They work exactly the same way as honda's vtec, i.e. two cam lobes. They make about 190hp at the fly standard and have a rev limit of 8200. A custom bell housing would be required as well as a custom plenum and headers as they only came in fwd. but in the us guys are making close to 200 hp at the wheels (FWD) with sr16ve cams, headers and chipped ecu and the limit extended to 8500. If you kept it standard you would be pretty close to your hp goal and it would have factory reliability. Downsides are there aren't alot of hot up parts. (but do you need them?)
the solenoid for the cam lobe switching is on the gearbox side of the head (i.e the back)
the custom parts required may cost a fair bit
and of course the fact that bugger all people have converted sr20ve's to rwd so you would have to learn as you go.
Also i have absolutely no idea how much a sr20ve would cost in oz, that alone might blow the $5000

Basically i just want to see someone do a rwd sr20ve since i don't have the stamina to see it through

just my thoughts
Nick
