Ecumaster forum

Thought i would start a project thread , specially as it came out the garage today , still a a few jobs to finish off but getting there .

Nice! I didn't know they made the 205 in yellow. Are you allowed to move the battery, or use something smaller like sealed AGM jet ski battery? It would be good to get your air intake away from hot air from radiator. What intake manifold are you using?

yes im going to fit the filter where the main beam is , will get a slim battery and should have enough room , i can move it but if there is no need i wont . its only there atm so it has a filter on . the intake is a custom made one .


has a st215 head , oversize valves , hks 272 cams , CP pistons and eagle rods i am hoping it will get around 600hp when mapped . Turbo would be the next upgrade something that spools a bit better as this is an older type ( ITS T61 )

Nice. Good idea move battery to place IC tube.

little batter fits in nice , still not sure of that catch can though .

Had 1st bit of mapping today at Jam-Sport , few niggles early on but we got there in the end . need to wired ebc valve into the ecu now and a couple little jobs and can go a bit higher on boost next , was only 1.4 bar so far

thanks to Sam ..

Nice results. Good job

No problems Richard.

Was good to meet you, and was nice to end with a good result.

Now we need to see some videos of it in action

hey Sam , i just been looking at that fuel pump and i have bypassed the resistor and now i have 10.6v to the pump , was hoping to get more tbh , so looks like i have to fit a relay at the back and run cable

I had the same problem. Rewired fuel pump and runs perfect. Ground directly to chassis (rear Seat bolt) and new +12v wire from stock relay.

you bypassed the EFI fuse then ? i get 12.25 there , seems to lose a lot of volts in a few feet

Oh SAM quick question my Torque curve is that wheel or fly ?

Fuel relay (box bolted to radiator) have 2 +12 wire bridged. I removed this pin and add new wire to pump. Before unestable value 9v/11v. Now 13v and my fuel log show richer lambda from 0,85 to 0,80 At 6000rpm and 1,2bar

yes i know center pin of the 3 smaller ones is the one that goes to the pump ( blue with black line ) i will try that tomorrow just run outside the car to test

Tomorrow I will post picture. I think that we arent speaking to the same relay. I mean 5 pin fuel pump relay not EFI relay. Stock wiring, upper left corner and lower right corner are bridged. Sorry my english, tomorrow show you my picture

Torque on the graph is flywheel torque.

rewired now , fitted a relay in the back , nice 13.8v at the pump , pressure is ok at idle so all good

finally how rewired?

ran a wire form the battery , fused 15amp ( amps was a guess ) . fitted a relay in the rear , used the stock pump power wire as a switch for the relay , ground wire in back , cut and taped small power wired that goes to the pump . used thicker wire from the relay to supply power to the pump , job done easy .
