hi all... is ther much difference between an itr b18c and a sir-g b18c,,??if i am swapping for a sir-g b18c engine into a jordan could i use a type r ecu or shud i use the sir-g ecu?
also should i go s80 or s4c both non lsd..:yuno:
 
nice i was unsure,as u probly already know the sir-g is 180 and the itr is 200, wats the best way to go about getting her to the 200 mark without spending a lot of cash...:cool:
 
Isn't the sir-g with a b18c4 and if so change of head to a b18c head will get you close to the jdm b18c but generally exhaust air filter will give you a few ponies
 
It's stamped B18C because its off an import. It's not much quicker than a B18C4.

I'd save your money and get a Type R B18C.
 
I just read up on this and have as c4 but with 10 more HP and still with the dule runner butter fly inlet manifold so as said save money and get a real type r b18
 
the engine is out of a jdm dc2 sir-g and is a b18c on the block,seemingly 178bhp standard as i checked on wikipedia with an s80 box,has a mugen four branch,magnacore leads,oil cooler,no smoke,sounds healthy,exedy clutch(good),I am taking out a b16a2 out of my jordan to replace with the b18c,i know the car as a mate owned it n im getting the conversion at a good price,
i would go the extra few euro for a type r b18c but its hard to get a good one that can be test drove 1st.. wat do us think??
 
I went from an Integra SiR to a '96 Type R.

The power and vtec difference was amazing. Personally I'd hold out for a Type R engine.

Highlights of B18C Spec R compared to standard B18C GSR

1. Camshaft - Wide-angled, high-lift, high-durability camshaft
2. Exhaust Valve Spring - High-lift, dual-layered spring
3. Spark plug - High-heat-type #7 platinum plug
4. Engine Stiffener - Aluminum die-cast, high-durability, one-piece type
5. Crankshaft - Full-counterweight, 8-weight, high-output, custom crankshaft
6. Connecting Rod - Custom TypeR rod, high-durability, lightened
7. Pistons - High-compression, low-friction, custom pistons
8. Inlet Valves - Lightened inlet valves
9. Intake Manifold - Custom tuning, single-port type.
10. Throttle Body - 62 mm (2.4 in) wide-mouth throttle body.
11. Inlet Valve Springs - High-lift, flat-surfaced, dual-layered spring
12. Port Buffing done by hand
13. Fastening of Connecting Rod done with micrometer. Even though all engine component parts are done by a micrometer and not eye balled.
14. All stainless steel headers
 
cheers for d posts, is there a difference with the inlet mani? if so could i put an itr intake mani on it?
 
well,learning somting new everyday:confused:
im getting d whole car pritty right,it will b alot better than a b16a2 nyway..

get the right map, and these are dc2 killers.

As and when you have it tuned, get the IAB's and vtec to both come in together, you will lose a little bit of mid range, but will notice massive gains higher up in the RPM range.

I had a b18c gsr engine that dv8 on here has now and he will vouch its fast. All i done has changed the inlet manifold to a skunk 2 one that has to be specifically a gsr one and a j's racing intake and it made 204bhp with a proper map

true story!^^

GSR lumps are vecious with good maps.

easily get an ek and an eg into the low 14's/14 flats if driven well.
 
cheers for d info nuno and grantek,now what are AIB,s??
and was d skunk 2 inlet mani expensive,did u map it on d standard ecu?
 
The IAB's are the extra butterfly valves u have in the intake manifold, they open at 4.5k and Vtec crossover at 6k.

They help midrange power delivery.

The stock ecu is JDM so you can run it on stock map for now, only issue is ur limited to 112mph I believe, should be just about as you change to 5th gear.

The stock ecu is also mappable if you wanted to do that straight away or at a later stage.

ah now i get ye,thanks,

Wat is the best way to delimit it? rsm?

Also this is going into a jordan,can i use my own loom and will i need a harness for the ecu change?or just plug and play??

also another quick q,i have a s4c and an s80 lsd,witch would be a better box for performance?
 
if its an integra type r s80 i would go with that for performance, much stronger box can take a bit more abuse :drive:

could also put 96 spec 4th and 5th gears into it if its a 98 spec?
