eh?

if the turbo isn't on boost, you're in the wrong gear, that's what he's saying.

If I were starting again I would get a nice low milage z18xe, some headwork, build some nice tb's, get it running right and then plenty of mapping. Im sure 170bhp will be pretty easy to get if done properly and then get some cams and take it from there.

pros: cheap to buy, straight forward fit, healthy amount of torque, light, not been done before, the benefits of tb's over turbos is massive, low milage are easy to find.......

cons: erm.... well.... apart from not being done much before (if at all in the uk?)

Z18XE's over here with induction sorted, decent high flow extractor, exhaust, and a remap has seen just shy of 150-160bhp at the fly. they respond very well to breathing mods, and has been seen previously, they are bloody strong engines. they can handle a lot of power without too much engine strengthening

No reason why a turbo would give bad traction, the throttle is adjustable, and changing gear means you can keep it on boost so no reason for a sudden surge?!
The problem I see with the turbo engine is front end weight, big downside. Add to this the cooling issues with having a red hot lump of metal under ur hood and its a big no-no for constant track use IMO. Lots more to go wrong with turbo engines due to the fact that there are more components. Simpler solutions are nearly always better.
I would recommend a 1.8 small block N/A. 170 bhp should be easily achievable without any negative weight issues, and trust me 170 bhp is plenty for some serious track fun
Also, why is torque such a big issue for u? If the car is prepped for track use (low weight) then torque isn't really an issue

Ha hello chap - i was hoping you would reply! i was talking to Dar about when he took you out and how you was impressed you was

Torque is very important to me. Its what makes the car grip and go!!!

I have come to a conclustion about what im going to do.
Progress thread to follow

I would also like to say thank you to everyone who has contributed to this thread - its nice to see we can have some intelligent car conversation!

I was impressed with dar's car, but I still believe that a 2.0 is a backwards initial step. I agree that they can handle but you put yourself at a disadvantage by placing extra weight over the nose.
IMO torque is required for towing caravans, for heavy cars and for comfortable road driving. For a track car that spends its life 1rpm shy of the limiter torque isn't really that important (correct me if i'm wrong!). My nova puts out a feable 119lbft of torque and is more than a bit nippy.

Yeah thats totally correct.

Bike engines don't produce torque, but wne it only weighs 160kg and revs to 16,000rpm, who needs torque

I want torque

I dont want to spend serious cash to only give myself a 3lb advantage, i agree a small revving smallblock is a good idea, but if i can extract some torque with it then im sure it will make for an entertaining drive.

Another vote here for the 1.8 small block. Its the way foward no need to spend money on new mounts driveshafts and all that just throw it in with some TB's of course.
I think its a faily well tried tested way

Sorry not touching TB's.
Really not my thing considering it will be used most days.

Would the Z18XE really need throttle bodies? I'm not familiar with this engine, but surely just working the head, cams, exhaust, a mantzel/lexmaul inlet type thing (if it has a bad inlet?!), bottom end bolts and a re-map would see circa 160-170bhp

All the above is based on guestimate so don't hold me to it!

Yeah, should be about right, if not a little more.

It's a torquey engine too, far, far more then the 1.6.
