Hi there new here!!

I am driving a JDM Spec 1999 Honda Prelude Type S.

What type of cams should i upgrade to which will gain HP but not loose overall drivability ??

Should I change the pistons too?

 

if you have a type s, you're already running 11.5:1, so unless you're running race gas or have really high octane over there, you're not going to be able to go a lot higher in compression on the street. i'm definitely not experienced or an expert on cam choices, but a number of people like the skunk2 pro1's or pro2's; the pro1's will obviously be a bit more tame for the street. jun's are always a good choice too if you can find them.

 

Our Octane level is pretty good here. We have 98. How much more real gains are there with cams.

 

Skunk Pro cams are not going to be very good for drivability.

Something with milder primaries, like the Skunk tuners or JUNs or something like that would be better in that regard.

 

Type S's have 11:1 pistons not 11.5:1. Also the type s has pretty good cams from the factory. I would recommend staying with them and retaining your reliability. Maybe go with a turbo/supercharger setup.

 

Turbo on a 11:1 compression? Are you serious??

 

Ya cause turbo/supercharger will so make his reliability better..

 

Sorry Bro Turbo/SC regulation in Singapore is very strict... easy to get caught, penalty is also heavy. Thats why i not keen in doing force induction..

 

The Turbonator is very discreet

 

yes
With the way aftermarket cams wear away on the h22 heads i wouldnt recommend them for a dd. When i say a forced induction setup im talking about 6pounds. Nothing serious. In this application i would try and get my hands on a JRSC. Stay obdII with either emanage ultimate of AEM FI/C so you can retain atts. Ive seen it done before. Ive seen boosted type s motors before and you should check out 98vtecs newest build.

 

I am sorry Turbonator?? U have a web i can read or see pics? Thanks in advance.

I read a site saying that overpowering the prelude with ATTS will cause ATTS to have problem is it true?

 

Sorry Bro i dunno what a JRSC is?? Do u have a link for me to read up more about this mod? And what is Stay obdII?? Sorry I am not very good with acroms...

 

JRSC = Jackson Racing SuperCharger
OBDII = On-Board Diagnostics II

Aftermarket Cams should not wear on the Head IF they are installed properly.

lol, He was joking.. It's nothing you should even be concerned with.

True. The ATTS system has a threshold of how much power it can handle before it will not be as effective as it was with lower/stock power.

 

O I c haha thanks. I cant find a good site to see cost and pic of the JRSC for Prelude Type S. Any good links?

JRSC with your Type S motor may not be a good idea, especially with the humidity and climate in Singapore. You may need more than 98 Octane in Singapore to reliably tune the JRSC with your 11.0:1 CR Type S motor. I'm also not sure if the Asian octane grades/levels are the same as the levels we have here in North America.

 

Get it tuned, add the usual bolt-ons, then work on lightening it up and the suspension, then after all that.....call it a day. It's just my opinion, but I consider that the same as an Integra Type-R leave the internals alone and add everything else to improve air, exhaust, and fuel flow.

 

Singapore Octane Rating is actually alot better then US. Thats why we have alot of high com 4cyn cars.

 

Tuning is the most diff part in Singapore.... to tell u the truth most garage in SG dun know nuts about tuning.

 

Well get an ecu with a base map on it and learn to tune. That seems like the only other way. It might seem crazy for me to tell you to "learn how to tune" but It's alot of people doing it. So it can't be that hard. And hell if you learn, you'll be one of the only tuners in your area. That's ground for making money. Just an idea.

 

Singapore does have higher grades of Octane than here in North America, but that's also a result of the weather and humidity. As for high CR cars in singapore, I'm no stranger to that as well, as I have friends part of the Singapore Honda Club and also some from Choon Motorworks with very nicely built high CR b-series motors. However, high CR with 6psi (stock for JRSC) of boost from the JRSC, may cause some issues, especially if you are concerned about realibility.

 

I think Garage-R is a HKS dealer and also tuner. They may be able to help you out.

You may want to check Choon Motorsports forum, as that forum is more technical than the Singapore Honda Club Forum.

 

Why not ignore Cams all together. On my Type S is all stock apart from Mahle Gold 11.5:1 pistons and a better panal filter and is pushing closer to an unproven 230Bhp. Stick this with a better manifold and exhaust, bigger throttle body port matched to stock intake manifold and possible Skunk 2 valve train minus the cams and and an ATTS friendly retune is guess closer to 250Bhp. And would be safe, reliable, good daily driver and still give a goo mix between economy and performance.

 

98 octane is going to be about 94 octane in the US. Which is a little higher than the US pump average but not a whole lot.
