Skunk 2 inlet for D series

[spudley1988]

Hey guys just needing a quick bit of advice. Been offered a skunk 2 inlet manifold for my mb3 for £100 but have never had any dealings with changing inlets. Heard it can be very worthwhile but what do you guys thinks of them? Also heard i may need to blank off my EGR valve? Is this an issue or not? Any help and comments will be welcomed.

This intake should have a lot of complementing mods to see a benefit.  And our stock vtec-e cam will not really take advantage of it.

 

A little example, D14 engines that have the crapiest intake manifold like this (http://i55.tinypic.com/2it0y28.jpg). When they change the IM to D16Z6 there is no noticable effect. Of course this is a good uograde but on it's own you can't feel anything different.

 

It's a good investment for the future but if you plan to stay vtec-E I don't think is very worthy.

 

EGR it's not an issue, you'll just have two hanging cables.

Aw that sucks. So def not worth buying? Other modifications i have are a full stainless exhaust manifold back with a de cat and an induction kit. Would the inlet compliment this or still not enough due to our v-tec system?

Well it's certainly a step forward but like I said at this state it's likely that you won't feel any improvement. My advice is use the money for shorter/hybrid gearbox and/or mini-me, those should be your next steps. You must focus on the weak points of this engine, the intake manifold is definitely not one of them. (They are exhaust manifold, gearbox, EGR, vtec-e, ECU. All of them made for economy, not power)

Cool thanks for that guys going to give it a miss and hunt a 1400 gearbox instead lol . Also what benefits will i get by blocking the EGR valve?

If you want stock gearbox, here are your options:

 

D13B2 facelift (only from as 1995 model !!!!):

This is the best stock Honda gearbox:

3.250 1.900 1.250 0.909 0.750 4.437

It has the shortest final drive and gears. With this gearbox you'll have the best acceleration. It's S20 (gearboxes before 96) so it's lighter. Only downside 5th is a little shorter.

 

D16Z6/D16Y8:

3.250 1.900 1.250 0.909 0.702 4.250

This is again a good choice. The best thing is that your MPG will be the same as the stock gearbox (the rpm will be a tiny bit higher).It has short gears and the final drive is reasonably good. D16Z6 is S20 so it's lighter, D16Y8 is S40 so it has stronger shift forks (If you're not going on the track it won't matter that much).

 

D14A7/D14A8:

3.250 1.782 1.172 0.937 0.750 4.437

According to me this is the worst option. It has the shortest final drive which is good but 2nd and 3rd gear are long. So comparing it to D16Z6/D16Y8 you will have a little bit greater acceleration in 4th gear but shorter 5th gear so MPG will be less. It's not worth it but if can't find the other option it' reasonably good.

 

EGR cloggs your manifold with carbon, I don't think it helps with MPG at ALL... And I was told EGR on Hondas work differently   and opens up when you floor it which will cause a decrease in acceleration. Maybe it's a good thing when the car is new but you don't need it.

 

I hope this helps

Thanks very much for that its all veryy helpful indeed. Im guessing the first 2 gearbox options are out of a hatch? sorry about all the questions just not much of an idea about a lot of this lol. Appreciate all your comments though and once i find where these gearboxes come out of ill be hunting one of these bad boy out.

 

I had a corsa sport a few years ago (yea i know crappy cars but ive learnt my ways lol) and i was highly recomended to get rid of the EGR valve on that as well so im guessing its much along the same lines in the hondas.
