Hi there .
I am building a 13BT motor to put in a RX2.
I would like to know what mods i would have to do to make +- 350 hp.Car is going to be used for street and drags.
Would a street port be OK ?
What is a race port ?

What i have at present is :
Hurley 2mm seals and springs.
complete gasket set.
To4E turbo - is this OK - recommendations please !!!
Turboxs dual boost controller.
large intercooler +- 40cm high x 60cm long x 7cm thick
would a chargecooler be better ?
Microtech MTX8 management system.
6 x 550cc injectors on a flowed and port matched manfold.
4 button sintered clutch.
2 bosch Mercedes fuel pumps and a rising rate fuel regulator.

Any advise would be welcome ! ! !



Thanks ! !

 

just out of curiosity....why 6 550's? why so many and not just larger ones? is it because of availibility? i am doing a rx2 turboII to4 in an rx2 right now. PM me.


what are the times you are looking to run?
to give you an example of a similar car, a friend of mine has a turboII motor in his rx3 with 2 420's as additional fuel with a aic...has a t04 and uses the stock tII ecu (for now) with a 9in rear. best time to date was a 11.02 @119 with running extremely rich and IC pipes blowing off at the end of the track

 

Availability is a problem ,fortunately i had spare injectors from a couple of engines that I put in VW Beetles .Fitted engines with 45 sideraughts.
I would be happy to get into the 12/13 sec bracket and improve from there.
Will be fitting a toyota limited slip diff with 4.3:1 ratio.
9inch to big and heavy.

 

it will not break though....
i dont see 12's being unrealistic at all...

 

A nice port would work great I reccomend a side port to everyone. There are several terms for different size and shape of ports. a Street port is usually used to describe a conservative side port, I would assume that a race port would be a larger side port.

It sounds like you have most everything you will need to make that kinda power. Interesting selection in parts though. Will that managment system allow you to run 6 injectors? Why 2 fuel pumps when one pump will support much more than your goal?

You could probably do without the regulator also as 6 550 injectors will support your goal as well.

 

The management system can handle additional injectors
its usually used on 20b's.as for the fuel pumps ,we dont have the high volume pumps available and if you can get them they are extremely expensive.Our currency is the Rand wich is 10.5:1 against the dollar.$100 is to us like you spending $1050.Engines are fairly cheap though at+- R3500 (+-$350)The management system
is Australian and the cheapest available to us at R7500 ($750) Haltech ,wolf are +-R14000($1400).
