I had headers imported from someone on ebay from the states and it wasnt that bad. about 225 all in delivered but they arent stainless.

As for an MOT find a friendly tester and tell him you have a new engine fitted from a 1991 car. That way they cant test for the cat. Its what I do on mine!!!

What is the power output of the japanese 2.5i engine? I have a jap import and assumed it was the same engine and output as uk car.

**kenholland** · 11-7-04, 8:15

Hi Barry,
It's 200 bhp (well, 197) as opposed to 164 on UK spec cars.

is that why its even thirstier than i expected. What are its performance figures like 0-60?

**kenholland** · 11-7-04, 16:13

No idea - but it's certainly quicker than my old KL03 engine as the Boxster I see regularly on the way home will testify.
As for fuel, I've not noticed an increase in consumption with the KLZE - it's sometimes even better.

depends how much you have your foot down. My jspec will do as little as 100 miles to a tank but then that requires me to get it off the clock and stay there most of the time!!! I personally thought it was a little thirstier but only just.

I have a question,

Why has the jspec got 195 bhp as compaired to the british model?

**cruisemad** · 11-22-04, 19:47

compression ratio is 10:1 not 9.2:1. Heads are flowed better, No egr valve, Different ecu and vaf, different cams, different inlet manifold and thats about it. You can bolt all of this (including high compression pistons if you really wanted to) to a uk engine. Without the pistons it should get atleast 190bhp. Oh one last thing the fuel rail runs a higher fuel pressure apparently???!!!???

Has anyone made a supercharger kit for the V6?

**Einstein** · 12-13-04, 17:57

Yes.. Thomas Knight Turbos (TKT) they were geeting bad reviews on their turbo kits.. so chamged to doing S/C's instead.. dunno if they still do them..

Much easier to fit than a turbo, (no exhaust pipes to weld)
No turbo lag, but less efficient..

After destroying my clutch & flywheel last month I decided to try using an MX3 V6 flywheel as recommended. When I offered the new clutch up to the flywheel and turned it you could feel that it was catching on the bolts holding the flywheel on. I had to grind the outer edges of the bolts to get some clearance!

Should I have used an MX3 clutch kit? I would have thought it wouldn't be up to the job?

Just slightly worried...

**cruisemad** · 4-11-05, 18:55

no should have been fine as the mx6 and mx3 clutch assemblies are the same and uprated mx3 clutches are the same part no as the uprated mx6 ones.

gilberti · 5-5-05, 14:35

Cruisemad how did you remove the EGR valve without the ECU complaining? Was it worth the effort?

**Mark 626GT** · 6-14-05, 16:13

Kyle, in your original post you made no refrence to nitrous oxide

If you would like me to prepare a text I can do?

**kenholland** · 6-14-05, 16:32

Mark, I'll answer on behalf of all of us:

YES PLEASE!
