sigh..

this is what I was talking about. Study la bro. My 4G15 only had a cam pulley. Didn't use any ECU other than standard ECU. But that's because the overlap or lift is too much for the ecu to balance out. You'll need the piggyback or a standalone to manage the idling. But with a mild cam you don't have too much to worry about. And you don't need to upgrade your injectors la, you're not going full on high cams.

Seriously find another mech/tuner if this is what this guy is saying....

But again - back to my earlier question - why do you need the cam la? It doesn't do much if your engine is this stock. Maybe a small power gain here and there but SOHC just basically means you move the powerband around a little, not so much have massive gains. You want massive go for turbo
That was why bro. lsm and me talking about snails/siput......lol

hehe not really my place to say this, but i takut he mod and throw lots into the car, then realize, the gains dont really reflect. nanti paranoid xmau mod car liao. This kinda engine imo best left mostly stock.... light mods only....lightened bits here and there are fine (dont significantly buang weight off the flywheel or anything that extreme)

well known fact, the roi for na cars is already so low... and these simple BUT not simple enough engines are not exactly the platforms where the gains are that significant.

**just realized its a carb > efi conversion.... the carb would have been nice here
Carb mod weber can get more power......lol

In other words, let him burn?
let him gain the knowledge he want to have. he is curious to know what are the effects/gains/loss from his modifications. EInstein fails many times before his major success. same goes to jack ma

with permission, read this. @Latebloomer
Dont jump too fast.
nice article. The only thing i disagree with in here is the eManage and the standalone ECU choices. eManage doesn't support full open loop and the siemens VDO will overwrite it in a day. And since this was written in 2010, there has been a lot of newer standalone ECUs to choose from.

yea... in this case particularly... carbs would have made more power... and is probably more mod friendly if the purse strings xmau bukak besar
My mechanic and myself played around those days. The weber in the 3rd Gen Civic was fast. I did it to my 2nd Gen Accord face lift model, that one probably body weight heavy, improve slightly only......lol

Hello guys.. restoration of my car is nearly done.. the carpet had been install, the passenger seat and of course.. the driver seat is a bucket seat. New dashboard, second hand meter with rpm and tinted. Only left now are the door trim, planning to change since the old one are gettin worst since the inside materials are falling off and the radio panel which didnt include with the new dashboard.

On the performance side.. nothing much for now cause spend lot of for the interior. What i had done so far for the performance are the absorber, which is Gab He series.. shud had gone for the Ha series since tat one can be service. I had changed to short shifter and my extractor to 4-1 include thermal wrap. Dont ask why going for 4-1 while mostly are using 421. Since changing the header my car rev quiet easily to 7-8 rpm. On the engine.. i just change the whole timing belt set and the water pump cause the old one is broken. Engine oil gearbox oil brake oil.. all changed. Im quiet happy for what i had done to the car. Tats all for now

Thermal wrap...its a ballancing act.
On the good side, it helps contain the heat inside the piping itself to promote flow and reduce heat in the engine bay. On the bad side, it can potentially traps moisture and promote rust which on normal steel extractor can greatly reduces its lifespan especially if the car is not driven regularly.

I wrap my waja pipe too but only at the curve below the engine. I did that as the curve is just beside the driveshaft boot. Heat and rubber boot does not goes along well, proven by the torn off previous driveshaft. Now i had to drive the waja to kebun every night and early morning.

If wrap on stainless steel pipe then should not be a problem then, right?

The material of the extractor tat i bought is aluminized. Probably have to change the wrap every 6-8 months i guess. On the good side they keep the engine bay less heat.

How about the welding part? Anyway, even stainless steel will get discolored with the heat..........
Not sure abt that but usually the weld area is the strongest part of a joint metal piece.
With wrap, its not discolored...its like your pipe got infected by some weird nasty skin desease.

I read somewhere that titanium wrap does not damages the pipe as it does not traps moisture compared to fiber type.Dunno if its a fact or just marketing gimmick.
I did check online and the price for titanium wrap is....ouch.

Bro Izso, what car are you driving?
