why dont you go 42mm TB's , emerald / omex , freshen up the bottom end. . I'm sure you would see over 180bhp.

Do you actually know what the engine is producing? i.e have you been to a rolling road?

Its quite common that people have not optimised what they have, losing bhp and acceleration through poor intake, exhaust design and non optimal jetting. Is there nice cold air going into the carbs?

A well setup 5jj should be putting out >160bhp (roughly 135 at the wheels) and with a 3.62 should be ideally geared for Brands. What was your top speed on the straight - it should be >120mph. If not it would suggest you are down on what you should have.

Food for thought before you start spending cash on upgrades.

One simple upgrade is to lighten your car - do you know how much it weighs? MNRs are known for being a bit porky.

Personally, if all is well and you just want more grunt, I would put a ZX12 in there. Cheap and plenty of power and can be simply tweaked to give more. Far more reliable solution than super/turbo charging.

The Rotrex kit we had on our EP3 Civic didnt come with an engine oil cooler, only a Supercharger oil cooler,
that car done 20k miles at Snetterton, Brands Hatch, Spa, Nurburgring and had no issues what so ever with oil temps,

The engine made 154bhp on a dyno dynamics dyno at the flywheel.
just looked at a video and at Brands the digidash is saying 121mph when i get scared and jump on the brakes so your pretty much spot on there.

I have no idea how much it weighs but being an older 1 i imagine its a fair bit, its being corner weighted next week so should have an answer.
