The Elise is now staying with me and no TVR is being purchased. Yay! So last night I ordered some parts. These include a turbo manifold, GT2871R turbo, 630cc injectors and a new funky clutch. The engine is getting pulled out and built so its low compression and bomb proof. Don't aim to make as much power as Franks as he is using a bigger turbo. The 2871R is good for about 370bhp. Hopefully this is what I will make. Car should be ready in about a month or so. Will post pics as and when I get them.

I also have a BWR kit lying about in the garage which once the turbo is sorted and has been running for a few weeks we might stick on. Watch this space.

What gearbox are you going to use? The standard one will be toast at that level.

Cool, glad to see others following....... If you go over 200 ft tq. you will need to get a proper gearbox.....

Check out www.monkeytuner.com for all the gory details. If I can help in any way let me know..

Gearbox will more than likely be the E153 out of the MR2 turbo but I might have a word with quiafe and see what they have available.

Frank, read your thread on monkeytuner with great interest must say you have done an excellent job on yours.

Who is doing the work? Well, I must admit that I alone will be doing it. Its a big project for me and no doubt I will screw up along the way but it will be fun and I should learn a lot. Once the car is put together than its off to the rollers somewhere to get it tuned. Fortunatley for me I have the Motec on the car so its not going to be an issue.

You are taking on a big project best of luck and watch your fingers........ Everything you need to know is on monkeytuner..
Remember the gearing is taller in the E153 so you will want that turbo to light up early...
Quaiff ?..... Good luck...... Have them pay for the R$D..biggrin

Dude quick note...... The E153 gearbox is larger than the C64 you must take that into account when making your turbo manifold. I had to redo the manifold to gain clearance for the compressor inlet when I changed the gearbox........ It's all on monkey..

Learn from others mistakes...banghead

Interesting stuff, good luck.
wonder what the outcome will be also how difficult it was/is and at what cost.

The outcome will be somewhere between 300 and 700 rwhp, cost will depend...

But that what mr darcy will do that about 370hp, that is only the turbo if I read that correctly?
and he will change some internals in the engine.
also a stronger gearbox.

forcedfed? prices or higher...they did not talked about another gearbox, but I can't find them anymore on my link list biggrin are they gone?

edit: found something about them so I guess they are still somewhere http://www.gglotus.org/ggtech/elise-forcedfed/forc...
could be old info though...
Ah I see something about DRS turbo oke, I did not know.(not enough on the web)


after it runs fine and all settings are correct he will maybe add the supercharger, I was wondering that would need a special intake to combine the both.
do you also have to adjust fuel and settings again after that? or do the sensors/computer do that for you.

Forcedfed are out of biz, DRS are a poor tuning shop that have blown a number of engines on their dyno, so I'd stay away from them....

The problem with most tuning shops is that they are using the customers car for their R$D and of course they never talk of their failures....
The gearbox will need upgrading at anything above 180 ft tq. The good thing is that the replacement E 153 has been taking a beating on my car for the past year with no issues.

I've done all the R$D for all the 2ZZ upgrades and you can find the good, the bad and the ugly on www.monkeytuner.com just search and you will find it in detail....
I'm not selling anything so it's all there...
Yes the stock sensors and stock ECU " when tuned" are up to the job

Frank I have to disagree about the Stock ECU. It seems to lack so much compared to the after market ones. I took mine off when it was super charged as, at the time, there was no one into it. The Motec is a much better piece of kit and with the additional add-ons can take a little bit more care of your engine and provide much more info. Its also easier to get tunned as I doubt I could have presuaded Charlie to come over and tune it. remote tune is a definite no-go.

I spoke to toyota motorsport and they are pretty cock sure of themselves that the up most limit the C64 and 2ZZ-FE can take is about 260bhp. Going above this limit and your in serious trouble territory. Gearbox will fail and you stand a good chance of blowning a piston.

Project got underway at the weekend where it took me all bd day to take the rear clam off. This is going to take longer than I suspect. My mechanicing skills are not the best.

hm...thats not as much as I would like to see biggrin Simon (the honda conversion man) also says the standard parts are up to 260hp, after that its asking for trouble.

so if you want to see say 330<>400hp in your Lotus its gonna cost you biggrin
stronger gearbox stronger engine(change some internal stuff) and the SC or Turbo parts...

I guess a Honda swap with gearbox and SC 300<>330hp could be in the same price league then? or even a bit cheaper cause you can sell the toyota parts?

Don't believe the crap from people that are tryin to sell you their product since they have a motive..... I don't

The stock ECU with a proper tune will do anything any aftermarket ECU will do and will still give you the safe guards of the OEM engine management...all the OBD2 codes and functions.
No need to spend thousande on something you don't need, take that money and put it into the engine or gearbox. Sinclaire motorsport can tune your car with Charlie's software.
The stock engine can take 280 rwhp the gearbox can take 180 ft tq. safely.....

Doing a Toyota engine/gearbox build is still cheaper and better than a Honda swap.....

I have no motive but to help you out, it's your time and money, your car...

Frank the Motec is already on the car I also no longer have the lotus dash board - it runs a AIM mpxl dash. The Lotus ECU will not do knock block or control the boost. I know you run the Lotus ECU but you where lucky to have charlie on hand and some other good people around you when you built yours. I unfortunatley don't have access to those people unless Igo through monkey tuner.

The honda conversion is not an option. It will cost me a lot less to build the engine, stick the turbo on then fit the E153 box (if I do indeed use that box and not a quife one.)

I did some short search for the E153 and found this, they also speak from a very strong box

http://newsite.monkeywrenchracing.com/product_info...

so you go from 6 to 5 gears, the gearchance stays the same for feeling?

Sorry to here you spent that money on the Motec, the stock ECU would have done everything minus the boost control.... Charlie could have a visit to his folks if he came over for a tune....

The 5 speed shifts even better than the stock box, Chril Randall had some fun in the car, if you get a chance ask him what he thought...
