what makes you think its aluminum block?
that would be a 4A63?

but in all context it won't be much than 120hp atw

 

Getting 150hp at the wheels on teh 4G94 engine is actually not that hard. The key to it is like anything doing the right mods in the right order.

Now firstly check this link that I have written up on the 4G93 engine. I will when I get a chance do one of rhte 4G94 engine later but it covers basically the same information but with minor variations including manifold work etc.

But for example, we just finished before xmas a 4G93 lancer with rpw stage 2 camshaft, valve springs, cam gear, single intake manifold ported with 60mm throttle body, cold air kit, Haltech plug and play computer, RPW extractors 4-1 race design and a 2 1/2" system.

This vehicle put out a nice 125hp at the wheels with complete stock compression, internals and on our first dyno run. WHat I mean by this is the vehicle will be coming back to us later, to play with camshaft timing and a more aggressive tune on a 98 RON fuel. I fully beleive this vehicle will be producing easily around 135 - 140hp at teh wheels with this combo working right and this car is a very mild combination - it has smooth idle, good power, lots of torque and we picked up 750 rpm on the redline with it rev limited to 7500 rpm.

The point being if we had gone for say a twin throttle body package, some of our higher compression 10.5 or 11.5 : 1 pistons, and head porting with an aggressive tune an easy 175hp at the wheels is attainable. And this is on a 1.8 engine.

Grab the 2.0 engine with its greater torque, and the peak hp woudl be similiar but the torque range would be flatter etc.

This is one of the things that many people forget about RPW, is that whilst we do sell and fit a lot of turbo kits to cars, our heart has always been with the n/a mods which we usually finish a car like this with these sort of mods every 2 - 3 weeks.

THe key to most of it though, is our Haltech Plug and Play computer systems which are removing many of hte limitations in the tuning, and there are no wiring changes to be made at all. This means that come testing time, you can remove the haltech, refit the stock computer in around 15 minutes and have it fully compliant with emmisions again (Depending upon what other mods you have done to it of course).

The majority of fast high horsepower producing Mirage / Lancers in the world usually have RPW gear on them which I think say's the most about us.

WE do have some veyr fast turbo's but the majority of our cars are ones that are built up over several years.

Anyway if its N/A, and you have a quiestion, feel free to ask me cause its what I certainly know best.

A teaser for you - we recently finished a full race engine for a customer in the USA for a autocross team, with haltech, qaud TB system, stage 3 camshaft, head work, 12.5 : 1 pistons, our header kit, RPW Under drive pulley and other minors and that has produced on the break in tune 220hp at the wheels on some VP103 race fuel. Once a more aggressive tune is done it is expected to punch out aroudn 260hp at the wheels - all naturally aspirated. THat is an extreme but a good example of what can be done.

 

I have a question for you. I have a stage 1 camshaft from you guys. If I would want to upgrade my camshaft to stage 2, could you give me some core charge for it?

 

No we wouldn't, you would have to sell your camshaft and purchase a 2nd new one from us. Although I do not beleive you would have many problems selling the camshaft.

 

I know, but I wouldn't sell it for alot either and your camshafts are not cheap either. Ok thanks anyway.
