Need some advice for 4g93 DOHC

[pinkdotdesigns]

To all the sifu's,
I have a 4g93 GTI engine (MMC Ecu). Currently the engine is 100% stock.
I'm planning to perform a few engine moddifications. I need alil advice on the modifications that I'm about to perform.

My idea is;
1) Change the trottlebody to enlarged Mikuni 4g63 Perdana trottlebody.
2) Change the intake manifold to MIVEC intake. (Which is better MIVEC or GSR?)
3) Port match the trottlebody to the intake manifold to the engine head.
4) Full engine job (Port & Polish, 5angle valve job).
5) After market valves, harder valve springs & highcams (billet prefered).
6) Full engine block rebuilt, ACL bearings, fully balanced, blueprinted & lightened.
7) Oversized pistons (increased compression) 82mm. (Whats compression
should I choose, simmiliar to MIVEC or 1.6 SOHC?)
8) Metal gasket, adjustable campuleys & 4-1 extractor with matching straight flow exhaust pipe.
9) Cold Air Induction, Oil Cooler, Better plug cables & plugs.
10) After market ECU. Will a rechip be sufficient? (Any recommendations?)

Any recommendations to modify my ignition system?

Btw I will be changing clutch to those racing type clutch. Can i still reuse the original 4g93 GTI gbox?

Thanks in advance to all the sifus.

I would suggest an after market ECU because for these kind of modifications a rechip won't make much difference since its still running on the stock ECU. With an after market ECU the tuner can modify the ignition to suit the modifications. Are you planning to use this car for race or street. You can still use your stock gearbox.

Bro not to offend you, but I didnt ask how much will it cost. I asked if there are any suggestions. If you dont have any suggestions, I'd really appereciate if you would not pollute my thread.

Thanks.

This car will be used for street. Ocasional racing. Btw aftermarket ECU, I dun have to go to the standard of a fully standalone ECU rite? I'm guessing that even Emanage with ignation harness will be sufficient rite?

 

[aarion]

since your are already dumping so much, might as well got for standalone. More flexibility and tuning capabilities.

 

[pinkdotdesigns]

hmmm, any concrete reason why I need standalone? If a piggyback can already do the things I need, why do I need to invest & waste money on a standalone tht serves the same function?

 

[aarion]

if there is not different then they wont canll it standalone and piggyback rite?

For the ignition i recommend HKS twin power spark amplifier. Suitable and good for 4g93 series. Racing clutch or semi can be use with ori. gbox.

Pinkdotdesigns,

I would suggest u to use the GSR intake manifold as the flow will be better!From wat u have mention above, a piggyback will be sufficient enough unless u r loaded then u can go for a standalone...hope tis helps!Happy Modding!

 

[pinkdotdesigns]

hmmm gsr intake. i cant use those evo3 tbody's rite?

Tis one im not sure, maybe u should ask ur mechanic!As i know using a mivec throttle body should be enough for 4G93P
